Send signalr message from server to all clients

This is related to http://stackoverflow.com/questions/7549179/signalr-posting-a-message-to-a-hub-via-an-action-method, but my question is a bit different: I'm on version 0.5.2 of signalr, using hubs. In older versions, you were encouraged to create methods on the hub to send messages to all clients, which is what I have: public class MyHub : Hub { public void SendMessage(string message) { // Any other logic here Clients.messageRecieved(message); } ... } So in 0.5.2, I want to send a message to all the clients (say from somewhere in the controller). How can I get access to the `MyHub` instance? The only way I've seen referenced is: var hubContext = GlobalHost.ConnectionManager.GetHubContext<MyHub>(); hubContext.Clients.messageRecieved("hello"); Which is fine, but I want to call the method on my hub.

gdb: exited with code 030000000375

I am teaching myself to use gdb and am running some random tests. It may be worth mentioning that I am using a portable installation of MinGW on Windows 7 x64. I've created a program which I know results in a stack overflow, and as I run through it in gdb I first get two SIGSEGV signals (no surprise), and then it exits (again no surprise) with code 030000000375. Curiosity getting the best of me... what the heck is that code? I googled it and found very little. Thanks!

How do I write my files to an nsbundle?

I am writing an iPhone/iPad app where I have zipped files come in which are basically the contents of a website which I can then run upon extracting. However I would like to put all these files and folders into a single file i.e. an nsbundle file so that I can display it to the user as if it were a single file and where it can then be deleted or moved but not traversed. (My app allows traversal of folders throughout the nsdocuments folder) I know that you can easily import your own nsbundle into your project and then read it into a website. But is it at all possible to write one using an already made directory structure with files and folders that must remain as they are, i.e. the web folder I described earlier? If not, do you have any other suggestions for my predicament Thanks and regards

Performance of parsers: PEG vs LALR(1) or LL(k)

I've seen some claims that optimized PEG parsers in general cannot be faster than optimized LALR(1) or LL(k) parsers. (Of course, performance of parsing would depend on a particular grammar.) I'd like to know if there are any specific limitations of PEG parsers, either valid in general or for some subsets of PEG grammars that would make them inferior to LALR(1) or LL(k) performance-wise. In particular, I'm interested in parser generators, but assume that their output can be tweaked for performance in any particular case. I also assume that parsers are optimized and it is possible to tweak a particular grammar a bit if that's needed to improve performance.

How to change display message in an ExtJs Combobox?

I have an ExtJs Combobox with multiple true and I want to show "X values selected" on the input field instead of "Value 1, Value 2, Value 3". I tried with select listener but when I set the value to the input field and then you call multicombo.getValue() it takes the value from the input field. I would need something like take the value from the valueField (a hidden input). My code: var multiCombo = Ext.create('Ext.form.field.ComboBox', { renderTo: item.id, multiSelect: true, displayField: 'name', editable: false, valueField: 'id', emptyText: 'Select', hiddenName: 'data[Model][' + item.getAttribute('question-id') + '][value]', submitValue: true, inputType: 'hidden', value: selectedOptions, width: 300, store: store, queryMode: 'local', listeners: { expand: function(combo) { var values = Ext.get(combo.hiddenDataEl.dom.lastChild).dom.value; values = values.split(","); Ext.each(values, function(value, i) { values[i] = parseInt(value); }); combo.setValue(values); Ext.get(combo.getInputId()).dom.value = values.length + ' selected'; }, select: function (combo, values) { if (values[values.length - 1].data.id === parseInt(item.getAttribute('not-applicable'))) { combo.setValue(parseInt(item.getAttribute('not-applicable'))); } else { var notApplicable = -1; var newValues = combo.getValue(); if ((notApplicable = combo.getValue().indexOf(parseInt(item.getAttribute('not-applicable')))) != -1) { newValues.splice(notApplicable, 1); } combo.setValue(newValues); } Ext.get(combo.hiddenDataEl.dom.lastChild).dom.value = combo.getValue().join(','); optionsSelected = combo.getValue(); Ext.get(combo.getInputId()).dom.value = optionsSelected.length + ' selected'; }, change: function (combo) { if (item.getAttribute('required') == 'true') { if (combo.getValue().length == 0) { question.findParentNode('li', 1, true).addCls("is_required"); } else { question.findParentNode('li', 1, true).removeCls("is_required"); } //There is no ExtJs equivalent for this $('#' + combo.getInputId()).keyup(); } } } });

MySQL groupwise max by the length of a field

`Product` table: id: int name: varchar(255) info: varchar(8000) I need to get a list of all products, grouped by name, and if some products have the same name then the one with the most data in `info` field should be picked to show. Another requirement is consistency - the same products should be guaranteed to be displayed every time. But performance isn't my concern at all with this. So the best I have come up with so far is this: select * from (select * from product order by length(info) desc) as product group by name My understanding that this *should* work in MySQL but does not guarantee the results. Is there any better way?

Replacing Binary function in a Shared Object with a custom One (Under MIPSEL)

I'm trying to break inside a device of mine which has a MIPSEL core (Little endian MIPS). I mainly want to do that because the software that came on it is kinda broken and doesn't works as intended (and the manufacturer won't help me out because i don't buy thousands of units monthly). This device has a telnet console and i have already a firmware upgrade which modifies a Shared Object (a .so file) which has relocatable code. There's one function i know is called on that .so when i access a certain feature of this device and i've already done a binary to modify /etc/passwd so i can telnet in (this can be done after i manually flash my custom firmware myself). I've already "objdump" both files and have the dissasembly of both. My question is: How can i replace a given function from the original library with my custom one so i can run my code on the box? I know objcopy can work, but its kinda difficult to get documentation on it to achieve this. What i want to do is kind like a virus, although i don't want to distribute it nor break into other's peoples devices (btw, this device i'm talking about is VERY rare).

Google PDF Viewer not able to access restricted areas

The site that I am building requires a user to be logged in at all times, or they'll be redirected to the Login area. I am having a bit of difficulty in that I have an AssetsController which serves out files and images, but this has a `ActionFilterAttribute` on it that redirects users to login if they aren't. This is all fine and desired except that I am using Google PDF viewer to render pdf files embedded within an iframe. With the role on, it returns the page source as a the pdf unless I remove the ActionFilterAttribute. Obviously, this isn't desired as I don't want people to access all of the files on the server without permission. However, Google isn't logged in to my site so I'm wondering how I can remedy this problem. If you need any code to clarify the answer, please just ask.

How to check if Directory is Accessable without catching System.UnauthorizedAccessException

I have searched and searched through the net but couldn't find a good solution for this problem. Here my code: protected bool isFileValid(FileSystemInfo ifo) { if (!ifo.Exists || ifo.Name.StartsWith("$") || ifo.Name.Equals("System Volume Information")) return false; if(ifo is DirectoryInfo){ try { ((DirectoryInfo)ifo).GetFileSystemInfos(); } catch (Exception e) { LogUtil.Debug("Exception in isFileValid" + e.Message); return false; } } return true; } Is there any way to check if i can access the Directory other than to try catch the Exception? The problem with this approche is that it gets realy slow if there are many directories i can not access. What i mean by "access the Directory" is the call of `GetFileSystemInfos()` without exception. `isFileValid` is called by my application for every `FileSystemInfo` to determine if it is accessible in the way i described. Thanks in advance for any ideas how to solve this.

Reading integers from keyboard in Assembly (Linux IA-32 x86 gcc gas)

I'd like to know how to read integers from keyboard in assembly. I'm using Linux/x86 IA-32 architecture and GCC/GAS (GNU Assembler). The examples I found so far are for NASM or some other Windows/DOS related compiler. I heard that it has something to do with the "int 16h" interrupt, but I don't know how it works (does it needs parameters? The result goes to %eax or any of its virtual registers [AX, AH, AL]?). Thanks in advance, Flayshon. :D

I heard that it has something to do with the "int 16h" interrupt, but I don't know how it works (does it needs parameters? The result goes to %eax or any of its virtual registers [AX, AH, AL]?). Thanks in advance, Flayshon. :D

Validation values

I'm trying to validate my values for alphabets and numberic as well as checking from database. I have created a function of validation and declaring my onclick button with validation function. Function: <script> function validate() { var StudentID= document.getElementById('StudentID').value; var StudentName = document.getElementById('StudentName').value; var StudentAdd = document.getElementById('StudentAdd').value; if(StudentID.length ==0 || StudentName.length ==0) { alert("Please do not leave any blanks"); return false; } else { if(isNumeric(StudentID)) { alert("correct") } else { alert("Numbers only!"); return false;} alert("Correct correct"); } return true; } </script> Sample Form: <form id="Student" name="Student" method="post" action="nextpage.php"> <input name="StudentID" type="text" id="StudentID" value="<?php echo $StudentID?>"/> <input name="StudentName" type="text" id="StudentName" value="<?php echo $StudentName?>"/> <input name="StudentAdd" type="text" id="StudentAdd" value="<?php echo $StudentAdd?>"/> <input type="submit" name="submit" value="Submit" onclick="return validate();"/> </form> I have already declared return validate function instead of calling my nextpage.php. But nothing popup for any alert. Kindly advise. Thanks

Match functions and function calls in C using regex

I am fairly new into regexes, so I wrote the following simple regex using positive lookahead that detects functions and function calls in a C source file- \w+(?=\s*\() It works fine, but the problem is it detects non-function syntaxes like `if()`, `while()`etc too. I can easily avoid this by saying- (if(?!\()) | (while(?!\()) But the problem is how to combine the second regex with the first one? I cant `OR` them, cos the first one still matches `if()`, `while()` etc and in an `OR` expression, its enough if one of the term matches. How to combine these regexes or have a better simpler one which will not match non-function syntaxes like `if()`, `while()`

Want to update table row in asp .net mvc 3

I have 2 columns in my table named `CreatedOn` and `ModifiedOn`. Of course, In the form I dont want to show these two fields even as in hidden filed. When I post the same form I want to change `ModifiedOn` by Current DateTime and Want to keep `CreatedOn` value as it is. But as I have no hidden filed name CreatedOn, it sets it to null in the database. So I then I used the code below public ActionResult Edit(User user) { if (ModelState.IsValid) { var OldInsObj = db.Users.Find(user.UserId); DateTime UsersDateCreated = (DateTime)db.Entry(OldInsObj).Property("UsersDateCreated").CurrentValue; user.UsersDateCreated = UsersDateCreated; user.UsersDateModified = DateTime.Now; db.Entry(user).State = EntityState.Modified; db.SaveChanges(); return RedirectToAction("Index"); } } I am getting this error An object with the same key already exists in the ObjectStateManager. The ObjectStateManager cannot track multiple objects with the same key. How can I solve this? Please don't give any blog link to read, I have already read some of them but could not. Thank you.

No moderate comment Box on Facebook-Tab

I try since 5 days to get the moderate status for a comment box on my custom facebook tab (created with woobox). But the only thing what works is the implementation of the comment box at itself. User can post under the content. But i dont get the moderate status so i can't delete or hide post. So i tried again only with the comment box code on a serval testsite. I created a tab with woobox and set on the html-part of the tab following content: > html> head> > > meta property="fb:app_id" content="my App_ID"> > meta property="fb:admins" content="my ID"> > > /head> > > script src="http://connect.facebook.net/en_US/all.js#xfbml=1"> > /script> > > body> > > div id="fb-root"></div> > > fb:comments href="added my link to the facebook_tab"> > /fb:comments> > > /body> /html> This is what facebook said to get the moderate status [here][1] so i tried the full code from there but failed.

How to keep elements hidden until listbox selection in parent is made? (MVVM)

I have a view in XAML where I have a listbox, and a selection in that listbox populates an area to the side with properties from the selected instance of the ChildViewModel. I have a few buttons in the ChildView that are connected to commands in the ChildViewModel. Before I make a selection from the parent listbox, these buttons do nothing as expected. How could I keep these buttons hidden until a selection selection in the parent listbox is made, thus creating an instance of the ChildViewModel. I know how I could accomplish this if these buttons were part of the parent view by binding the visibility of these buttons to {Binding SelectedItem, ElementName=listBoxName}. However, I am having a hard time accomplishing this within the ChildView because I do not have access to (and do not want to be dependent on) the element from the parent view. Please help me accomplish this, preferably purely within the XAML code.

NSTimer vs CACurrentMediaTime()

So I'm amidst my first iOS game and am struggling with how to go about the best way to integrate object movement. The game relies heavily on fast moving objects and constant, fast user input changes. As such, I'm trying to have object integration and the constraint solver run as quickly and accurately as possible (to minimize user input change in between successive game loop calls). More specifically, I'm unsure of the capabilities of the NSTimer class and CACurrentMediaTime() function. It's hard to test empirically because I'm not sure which have the larger error. For example, using an NSTimer with a repeating interval of 0.008 (~2updates/screen refresh) and calling CACurrentMediaTime() on successive calls, I find the time interval between calls varies from 0.0075 - 0.009. Hard to say which is responsible for the (small) inconsistency. So for determining the time step should I be: 1. Assume NSTimer is accurate enough to use the NSTimer time interval as the game loop time step 2. Use CACurrentMediaTime() to determine the time interval between successive game loop calls. Student and new to all of this - please be nice :) Any advice is greatly appreciated. Thanks for your time.

The problem is that I need to retrieve the jnction values that are missing. For example: Table A Table B Table C Table D -------- --------- --------- ---------- 1 4 7 A 2 5 8 B JUNCTION TABLE ----------------- 1 4 7 A 1 4 7 B 1 4 8 A 1 4 8 B 1 5 7 A 1 5 7 B 1 5 8 A 1 5 8 B 2 4 7 A 2 4 7 B 2 4 8 A 2 4 8 B 2 5 7 A 2 5 7 B 2 5 8 A 2 5 8 B So if the column 1 5 8 B is missing, when I run the query it shows 1 5 8 B..

Handling relationships 0- Noob

I have a User model that extends the built in Django User model: class CustomUser(User): objects = UserManager() tasks = models.ManyToManyField(Task) I created a User in the shell using: user=CustomUser.objects.create_user('fred', '[email protected]', 'fredpass') I have another model for Tasks and as you can see CustomUser has a manytomanyfield relating it to Task. How would I add and remove tasks that have already been created to be associated with the user I have created? I am a noob.

Open a Site as a Window in Google Maps

I'm not certain if this is a valid question for this particular site, but I am using the Google Maps API v.3, and I was wondering about a feature. I'm not sure if this is possible given the restrictions Google has on the HTML that it will interpret in an info-window, but I would like to be able to open a new web site in an infoWindow (or something similar to it). The application is a bit involved, but the basics are that I am trying to integrate the information from one site, which I can't actually access, with the data I display in my map. As a temporary fix, I'd like to simply open the secondary website in a window on the map and let the user sign in as normal. Does anyone know if this is possible?

Mock patching from/import statement in Python

I am trying to get mock.patch to work on the following piece of sample code: from mock import patch from collections import defaultdict with patch('collections.defaultdict'): d = defaultdict() print 'd:', d This outputs the following: d: defaultdict(None, {}) Which means that defaultdict was not patched. If I replace the from/import statement with a straight import statement it works: from mock import patch import collections with patch('collections.defaultdict'): d = collections.defaultdict() print 'd:', d Output is: d: <MagicMock name='defaultdict()' id='139953944084176'> Is there any way to patch a call using from/import?

I have a Sencha touch 2 application that uses a navigation view and has a list of items. When someone clicks on an item and I dynamically change title of the navigation bar to be the item the person clicked on and also add 3 buttons to the navigation bar. However when the user clicks on an item and the screen is re-sized to be small the title is not formatted correctly. Is there an event that happens after a panel is rendered so I can call refreshTitlePosition()?

CakePHP plugin models not associating when using Containable

I have a CakePHP plugin named `Foo` that has a component, no controller, and several joined models. It's structured like this: /Plugin/Foo/Model/ -FooModel1.php -FooModel2.php -FooModel3.php -FooModel4.php In order to connect with the standard (non-plugin) code, one of the plugin models is conditionally associated with a standard model called `Bar`. I don't believe this is relevant to the problem, but I want to be thorough. In `FooController` I make use of `Containable`, several layers deep: $params = array( 'conditions' => array('Bar.id' => $bar_id), 'contain' => array( 'FooModel1' => array( 'FooModel2' => array( 'FooModel3' => array('Something', 'FooModel4') ), ), ), ); So in my plugin controller I need to contain plugin models. I've tried prefixing the models with Foo (e.g. `Foo.FooModel1`) but `Containable` thinks I'm trying to get a model named Foo. In the `$hasAndBelongsToMany` array in the plugin models I've tried both `'Model1' => array()` and `'Foo.Model1' => array()`, neither of which work. How do I correctly set up this association? Side note: when I move the models out of the plugin and into the standard `/Model/` directory everything works fine. The problem seems to come from incorrect associations rather than the logic of the code itself. Thanks a lot for the help.

Deploying static media to a server separate from the main environment

I'm having trouble with some changes to a fabric deployment script. We are switching from using a prone to breakage NFS mount for hosting our static media to using a separate webserver that will host and handle all of our static media. The goal is that regardless of environment that we're deploying (test, prod, etc) that the upload_static_content command will only run on the static media server. Right now if we run `fab test upload_static_content` everything works out perfectly. The static content ends up on the correct server in the correct directory. However, if we run `fad test deploy` the static content ends up on the test webserver rather than the intended server. def test(): ... env.hosts=testhosts def prod(): ... env.hosts=prodhosts def deploy(): # Do some deployment stuff ... upload_static_content() ... @hosts([static_server,]) @run_once def upload_static_content() # Upload static content to a different server ...

Maximum number of characters in a field of a csv file using unix shell commands?

For example, given the file below: adf,jlkjl,lkjlk jf,j,lkjljk jlkj,lkejflkj,adfafef, jfje,jj,lkjlkj jjee,eeee,ereq the answer would be 8 because row 3 has 8 characters in the second field. I would like to integrate this into a bash script, so common unix command line programs are preferred. Imaginary bonus points for explaining what the command is doing.

As and when the task got added in the database all desktop browser clients got refreshed except mobile one. so you have any clue why mobile browsers doesn't get notified?

Need suggestions on thesis (Android)

I'm new here Well, long story short, I'm making an Android application for my thesis but still cant decide between two topics (initially three) that I've discussed with my adviser. - Kids tracker There are two modes here; Parents mode (Register a kid, Track now) and Kids mode (will make the app to work in background if activated. Will not show any icons). My adviser also wants that the kids' phone will send an sms to the parents phone every time the kids does not stay in a place for a period of time. The locations of the kids are taken from the service provider. By doing this, the parents can still know their kids whereabouts even if there isn't any internet connection available - Lyrics reader The app will show the lyrics of the played song, taken from either the ID3V2 tag of the mp3 file or the internet. User can also save the lyrics to the tag and edit other kinds of attributes like title, artist, album, etc. The shown lyrics will also be synchronized with the played song (doesn't have to be that exact) So...which one do you guys think will be simpler? I need to finish this in two months (yes, two months for a thesis =.=) and I'm not that familiar with Android programming (only learnt the most basics back then). What will be the hard parts in the development? What kind of codes or features or whatever we call them - will I need to use? Any help will be appreciated. Thanks so much

I have a WCF client, that asks for order confirmation and WCF service with two methods: 1) UpdateOrder - updates order data in database (UpdateOrder call comes from external service) 2) GetConfirmationResult - which holds return of result till order status will change from pending to something else. Question is, how to make notification from UpdateOrder to GetConfirmationResult, that order it is interested in status has changed in WCF? Update: would be best, if I could leave InstanceContextMode as Per-Call. ![enter image description here][1] [1]: http://i.stack.imgur.com/LGwfl.png

But if you put a checkbox in the second form - not necessarily to celebrate in the first. How to make a post-validation? Sorry for my english.

MySQL REGEX a partial word in a word

i try to match a word against other words witg REGEX in mysql but i cant get it right. For example is search for the word 'foo' then it should match the following (case insensitive): foobar barfoo barfoobar foofoo football foo-bar foo_bar And not match spaces between them like: foo bar I searched the web and found some REGEX but they don't match all the above options. This is my current pattern: REGEX '[[:<:]]'.$word.'(![:space:])[[:>:]] thanx in advance :)

Black empty table cell in HTML email showing in Outlook 2003 and less

I have been reminding myself how lovely Outlook and emails are. I have got a problem when my 'empty' spacer table cells are showing up as black table cells in Outlook 2003 or less, any ideas what this could be? I have spacer gifs and I have given width and set bgcolor on the tds but it's still causing this issue. I also had this when using spans to style text however changing them to divs solved this issue. Here is a snippet of my code: <!-- Introduction section --> <table id="intro" bgcolor="#ffffff" border="0" cellpadding="0" cellspacing="0" width="100%" align="center" style="font-size: 15px; line-height: 24px border: none;"> <tr> <td height="16" bgcolor="#fff" colspan="3"> </td> </tr> <tr> <td colspan="3"> <table bgcolor="#ffffff" border="0" cellpadding="0" cellspacing="0" width="100%" align="center"> <tr> <td width="60%" height="1" bgcolor="#99ad26"> </td> <td width="40%" height="1" bgcolor="#ffffff"> </td> </tr> </table> </td> </tr> <tr> <td height="2" bgcolor="#fff" colspan="3"> </td> </tr> <tr> <td colspan="3"> <table bgcolor="#ffffff" border="0" cellpadding="0" cellspacing="0" width="100%" align="center"> <tr> <td width="70%" height="1" bgcolor="#99ad26"> </td> <td width="30%" height="1" bgcolor="#ffffff"> </td> </tr> </table> </td> </tr> <tr> <td height="24" bgcolor="#ffffff" colspan="3"> </td> </tr> <tr> <td width="24" bgcolor="#fff"><img src="http://www.ukgbc.org/sites/files/ukgbc/email/images/spacer.gif" alt="" width="24" height="1" style="display: block;"/</td> <td width="512" align="left" bgcolor="#fff"> <h1 style="font-size: 30px; margin: 0px; margin-bottom: 25px; font-family:Arial, Helvetica, sans-serif; background-color: #fff;" mc:edit="intro_heading">Introduction</h1> <div mc:edit="greeting" mc:hideable style="font-family:Arial, Helvetica, sans-serif; font-size:16px; background-color: #fff;">Dear *|FNAME|*,</div> <br /><br /> <div mc:edit="introduction" style="font-family:Arial, Helvetica, sans-serif; font-size:15px; background-color: #fff;"> Lorem ipsum dolor sit amet, consectetur adipiscing elit.

Shopify: create a smart collection for products that do NOT have a specific tag

In Shopify I have a smart collection for all the product that have the "wholesale" tag. I'd like to create also another smart collection for all the remaining products that do NOT have the "wholesale" tag. Is this possible? Is there a workaround? Maybe creating a smart collection is not the best possible option. What I really need to do is just list 6 products that do NOT have the "wholesale" tag. Is there an easy way to do this? Thanks in advance, Augusto

Create array whose keys and values depend of other arrays

There are some topics narrowing my problem, but no one permits me to solve it.I have a csv file of terms from which i would like to count the number in a table of my db and to write the result in a new csv file. I need to create a new array, where each key would be a term of the first array and the value would be the related number of records in my database. Here are some examples of the input : Lactose Serine And i would like to get something like this: lactose, 25 serine, 3 So i have created an array whose values are the terms in the csv file. Then i input the values of this array in a sql query. And then, i have been unable to find the right way on the Internet or in the php documentation. The last line completely fails, but i tried it because it seemed to be the narrower mean to manage my task. Could someone help me ? Thanks in advance ! $termslist= array(); $file = fopen('fileterms.csv', 'r'); while (($line = fgetcsv($file)) !== FALSE) { //$line is an array of the csv elements foreach ($line AS $molindice => $molvalues) { if ( ! in_array( $molvalue, $termslist ) ) {array_push($termslist, $molvalues);} } } fclose($file); //print_r ($termslist); $molnumbers = array(); foreach ($termslist as $ancientkey => $ancientvalue) { echo $ancientvalue; $sql3 = "SELECT content from mols WHERE content like '% $ancientvalue %'"; $result3 = mysql_query($sql3)or die(mysql_error()); $count3 = mysql_num_rows($result3); echo $count3; $molnumbers [$ancientvalue['molnames']] = $count3['quantities']; }

Newbie: Setup .htaccess to utalise internal and external domain mapping correctly

Having a bad time trying to wrap my head around using a .htaccess file to setup my domain mapping. I have hosing package with 123-reg.co.uk and need to host two sites on one host. i have been advides what i need to do is setup a .htaccess to make the second site work, as currently it is only showing the HTML with broken images and CSS. the primary domain is www.wqbf.org.uk which only has a holiding page, so is setup with index.html and a single image in the root of the folder. This is held by 123-reg.co.uk Next is the 2nd website, www.sanreneguardships.com (Externally redirected and mapped from godaddy.com), which is setup as a site with multiple directories holding everything. The current directory setup looks like this Root - Index.html - image.png - /Sanrene - /Sanrene/HTML - /Sanrene/Images - /Sanrene/CSS - /Sanrene/Files All the files are held in respective folders, and according to 123-reg's "superb" technical help, first I need to contact a web designer and then I need to look at a 301 redirect script that does not do what I want to do. I finally got it out of them that I need to setup a .htaccess to remap the 2nd site to the correct folders Ive looked at the tutorial [Here][1] but cant get my head around it.

Delphi webservice call not in parallel

I developed an application that get messages through TCP server in parallel and calls a webservice from another webserver application. I noted that parallel requests processed by webservice server in serial. I forced webserver to have delay in response to enhance situation. I traced and found that webservice calls are in parallel by low level Delphi webserivce call serialize calls. I sniffed and found only one connection is opened and HTTP requests are sent one by one after getting response. My base web service call is as bellow var HTTPRIO: THTTPRIO; WS: TelephoneDispachServerSoap; begin try HTTPRIO := THTTPRIO.Create(nil); WS := GetTelephoneDispachServerSoap(false, '',HTTPRIO); CoInitialize(nil); r := WS.MaxMethod(10,20); finally CoUninitialize; end; end; What Should I do to send webservice calls in parallel?

Rails button_to with multiple line text

I'm writing a Rails application and I have button that I create as follows: <%= button_to t('.upload_html'), ... %> where the ... stand for the other options. So the button should have the text pointed to by .upload_html and it does. Now I want that text to have two lines. In the YAML file I had upload_html: "turn off" and now I want upload_html: "turn<br>off" with a line break inside the button label text. But this does not work. It displays the string literally including the HTML tag without linebreaking. What can I do to force the line break? Thank you!! Best, Patrick

ASP.NET MVC Patterns for Multiple Tenants and Plugins?

I am trying to understand how I can create an ASP.NET MVC site that exists as a VS2010 project in a solution, and then for multiple "tenants" I would create a site that inherits from that one. That would give the flexibility of adding modular features to one without affecting another one, and both could benefit from core library optimizations. Is that a crazy idea? What patterns exist for that kind of thing? I have done something similar for a webform-based site (adding DLLS as plugins), but not in MVC. All ideas appreciated. Thanks.

Unifying two classes while leaving some extended abilities. Simplicity vs Reusability

Note: My code happens to be in C#, but I don't think that's significant to solving the problem. Problem ======= I'm trying to reduce code duplication in two old classes we have that are both used for loading queries from XML. They both have constructors that take the XML location, both have `Execute` methods that accept a collection of SQL parameters and both provide various static overloaded methods to make it quick and easy to run a query with maybe a single named paramater, or no parameter, or one with a non-default SQL connection object. These static methods also accept the XML location as the parameter, and internally they're calling the constructor, and so on, and finally just returning the first DataTable of the DataSet. public static DataTable GetQuery(string queryName) { ... } public static DataTable GetQuery(string queryName, string parameterName, string parameterValue) { ... } public static DataTable GetQuery(string queryName, Hashtable parameters) { ... } public static DataTable GetQuery(string queryName, Hashtable parameters, IConnection connection) { ... } and so on. The *difference* between the two is that one looks for the XML file in the filesystem, and the other looks for them embedded in the assembly. Possible Solution 1 ======== I was thinking of unifying them into one that can do either, using different implementations of a separate `IQuerySource` interface, passed into the constructor, or something. But this would mean either the constructor would have to always be called ahead of time, or the `GetQuery` methods would need to be passed the `IQuerySource` object every time, as well. I'm trying to avoid things like that, because these `GetQuery` methods are used *everywhere* in the client code, for quick little things like `GetQuery("GetUserDetails","UserID",userId.ToString())`. Possible Solution 2 ======== Alternatively, I could create two very light classes, `FileQuery` and `DllQuery`, that would sit on top of the unified class, and they would always pass `FileQuerySource` and `DllQuerySource` down to the constructor and/or `GetQuery` methods. This would keep the client code small, but I don't want to have maintain (marginally thinner) versions of all the existing `GetQuery` overloads in two more places, in addition to the core class! Possible Solution 3 ======== Another alternative would be like the above, but exposing the unified class so you could call, say, `DllQuery.Q.GetQuery("GetUserDetails","UserID",userId.ToString())`, but then I'm not sure how DllQuery can intercept the call and make sure the Q instance of the unified class always gets the right source for the job. An additional complexity is that to get XML from an assembly, we're currently using `System.Reflection.Assembly.GetCallingAssembly()`, so wherever that's called has to sit directly under the surface of the client code, otherwise we'll get our Data assembly instead of the client assembly. I understand this question might be a bit subjective, but I'm hoping there's some well-understood and well-defined design pattern, or something, for addressing this.

Rotating UIViews become unresponsive

I have a UIViewController subclass that changes its frame when the UI rotates (for example, most commonly, the frame is the same size and centered in both landscape and portrait.) When the view rotates, the view visually changes its frame as expected. But the controls (buttons, scroll views, etc.) that end up in the area of the new frame do not respond to touches. The only controls that respond are the ones that have remained in the original frame (so, if the view moves down and to the left, controls or parts of controls in the upper right corner remain responsive.) Any idea what's going on here? Here's the code that changes the frame: - (void) setLandscape:(bool)bLandscape { if( bLandscape ) [self setFrame:m_landscapeFrame]; else [self setFrame:m_portraitFrame]; } And in the bigger view controller that handles rotation directly: - (void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration { bool bToLandscape= UIInterfaceOrientationIsLandscape(toInterfaceOrientation); [UIView beginAnimations:NULL context:nil]; [UIView setAnimationDuration:duration]; [m_pCurrentWindowViewController setLandscape:bToLandscape]; // (Some unrelated stuff happens here...) [UIView commitAnimations]; } To me this seems like a bug or at least poor design on Apple's part - there should never be a time when a view is in one position visually and another position in terms of control. But I'm just looking for a way to fix this behavior.

Finding the coordinates of a letter placed on TextView

I have a textview which contains longs text that covers half of the screen, In this textview I have two words at different position above which I have to place a blank layout which will give it a glass effect. I can do this by placing the textview in a framelayout and placing the layout above it. The problem is how will I get the coordinates of the words, as the text may be arranged at different position on different devices.

HTML5 Canvas - Performance difference between portrait and landscape on retina display

We're using a scaling technique to improve the resolution of our canvas web apps on the retina display. Basically, the technique described here: http://zsprawl.com/iOS/2012/03/html5-canvas-and-retina-displays/ However, we've noticed a SIGNIFICANT performance difference when running in landscape mode vs portrait mode. I've set up a jsFiddle test app to demonstrate this. You can notice the difference if you view the embedded version: http://jsfiddle.net/SaJ69/embedded/result/ (removing the /embedded/result/ will take you to the original fiddle. I could only have a post with 2 links in it) If you switch between portrait and landscape when viewing this on an iPad3 (you'll need to refresh the browser window between switches) you can see that portrait mode is choppier than landscape. When running this on my own webserver (not through jsFiddle), the results are much more noticeable. I tried to do some frame rate metrics, but they're only measuring the number of times we make draw calls, not the number of times the browser will actually update. Anyone have any insight into this? Is this a hardware related issue? We are theoretically doing the same draw calls and filling the same number of pixels right? -Chris

Is it possible to use Type.GetType with a dynamically loaded assembly?

Say I have this little bit of code: public static void LoadSomething(Type t) { var t1 = Type.GetType(t.AssemblyQualifiedName); var t2 = t .Assembly .GetTypes() .First(ta => ta.AssemblyQualifiedName == t.AssemblyQualifiedName); } What happens is that t1 is **null** and t2 is **not null**. I was confused since if I call it like so... LoadSomething(typeof(SomeObject)); then **neither** are null but what I am actually doing is more like this (not really, this is massively simplified but it illustrates my point): LoadSomething(Assembly.LoadFile(@"C:\....dll").GetTypes().First()); So the first part of my question (for my information) is... In the second case, since the assembly must be loaded up and I found the type out of it why doesn't Type.GetType work? And secondly (to actually solve my problem)... Is there some other way that I could load a type when I only have the assembly qualified name as a string that I know has been previously loaded by using the Assembly.Load methods?

push buttons are not working correctly

I have 2 push buttons, I am trying to state that if "1" button is on, turn off the "2" button, else if the "2" button is on, then turn off the "1" button. But at the moment what is happening is that if I turn on the "2" button, and then turn on the "1" button, then this works fines as "1" button turns on and "2" button turns off. But if I then try and turn "2" button on again, it doesn't turn it on, it remains off and button "1" remains on. Does anyone know why this is happening? Below is code: function btnclick(btn) { var context = $(btn).parents('#optionAndAnswer'); $(btn).toggleClass("answerBtnsOff"); $(btn).toggleClass("answerBtnsOn"); if ($("#answer1", context).hasClass('answerBtnsOn')) { $("#answer2", context).removeClass('answerBtnsOn').addClass('answerBtnsOff'); } else if ($("#answer2", context).hasClass('answerBtnsOn')) { $("#answer1", context).removeClass('answerBtnsOn').addClass('answerBtnsOff'); } return false; } below is html for both 1 and 2 buttons: 1 button: <input class="answerBtns answers answerBtnsOff" id="answer1" type="button" value="1" onclick="btnclick(this);"/> 2 Button: <input class="answerBtns answers answerBtnsOff" id="answer2" type="button" value="2" onclick="btnclick(this);"/>

Symfony 1.4 sfWidgetFormInputFileEditable customization

I am using the sfWidgetFormInputFileEditable widget for my users to upload images. I would like to see if there's a way to alter the way it works be default. When a user is adding a "new" object, I would like for it to show a generic picture, and when it's an "edit" then it can show the existing pic. I tried writing a PHP conditional statement but that's not working for me because when it's a "new" item I can't pull the parameter "getPicture1" because it doesn't exist. Thanks! My widget currently: $this->widgetSchema['picture1'] = new sfWidgetFormInputFileEditable(array( 'label' => ' ', 'file_src' => '/uploads/car/'.$this->getObject()->getPicture1(), 'is_image' => true, 'edit_mode' => true, 'template' => '<div>%file%<br />%input%</div>', ));
