I am new to latex i want to set a width and height of the mdframed. can any one help me to achieve this task.  \documentclass{article} \usepackage{xcolor} \usepackage{mdframed} \newtheorem{mdtheorem}{Theorem}  \newenvironment{theorem}%  {\begin{mdframed}[backgroundcolor=lightgray]\begin{mdtheorem}}%  {\end{mdtheorem}\end{mdframed}} \begin{document} \begin{theorem} Sample \end{theorem} \end{document}     My current output is ,  My expected output is
Consider this:  \documentclass{article} \usepackage[framemethod=TikZ]{mdframed}  \begin{document} \begin{mdframed}[innerrightmargin=0pt] TEXT\end{mdframed} \end{document}   This produces a frame that is much wider than its content:    I know this is not a bug: the mdframed documentation mentions a userdefinedwidth parameter that defaults to \linewidth. But how can I get a mdframed frame that has the same width as its content?   (What I actually need is a box with rounded corners and shading options; breaking over multiple pages isn't necessary. mdframed seemed like the easiest way to get the box, but if it's too much hassle to make it size to content, it would be useful to know so I can try pure tikz.)
How to find Oracle's installed version and release from a program? I've noticed the text of the Hot Meta Posts box is not within its limits. I guess this would happen for any question with a word that's long enough: "'Hello', says he. 'Hello', says I" — is this correct? I'm reading a novel in which once in a while a character says something like "I are", "He do", and similar stuff. I understand the author is just reproducing the way people talk on the streets.  However I've found a piece of text of which I'm not sure if it's proper English. One of the characters, who almost always speaks proper English, is reproducing a conversation that happened many years ago using the present tense in the following manner:     I was with this guy and "Hi", says he, "how are you", says I...   and so on.  My question is if the "says I" is proper English (a special case in which "I" is treated as a third person because we are relating in present tense something that happened in the past) or it's just kind of slang.  I was also a bit surprised by how the usual order is switched ("says he" instead of "he says") but to me it's secondary to the "says I" issue. How do I rename a domain and preserve SEO?

Personally counted every answer twice. What's the rationale for requiring that a field be a $\boldsymbol{non}$-$\boldsymbol{trivial}$ ring? The title pretty much says it all.  Of course, one answer (IMO unsatisfactory) to such questions goes something like "a definition is a definition, period."  In my experience, mathematical definitions are rarely completely arbitrary.  Therefore I figure there must be a good reason for insisting that a field be a non-trivial ring (among other things), but it's not obvious to me.  I realize that a trivial ring would make for a very boring field, but it is also a rather boring ring, and yet it is not disallowed as such.  EDIT: I found a hint of a rationale in the statement that "the zero ring ... does not behave like a finite field," but I could not find in the  for this assertion exactly how the zero ring fails to behave like a finite field. When searching on a site with  enabled (), I saw some  rendering issues: (and currently it's also in the )        Even though the LaTeX rendering is fine when opening the :        The LaTeX code is:  $f(n) = \begin{cases} 0,  &amp; \text{$ \omega&lt;0, \omega=1, \omega&gt;3 $} \\[2ex] -\omega + 1,  &amp; \text{$ 0\le\omega&lt;1 $} \\[2ex] \omega^2 - 1,  &amp; \text{$ 1&lt; \omega \le 2 $} \\[2ex] 3 \omega,  &amp; \text{$2 &lt; \omega \le 3 $} \end{cases}$ What are the functions that are their own inverse?  (thus functions where $ f(f(x)) = x $ for a large domain)  I always thought there were only 4:  $f(x) = x , f(x) = -x , f(x) = \frac {1}{x} $ and $ f(x) = \frac {-1}{x} $   Later I heard about a fifth one     $$f(x) = \ln\left(\frac {e^x+1}{e^x-1}\right) $$ (for $x &gt; 0$)  This made me wonder are there more? What are conditions that apply to all these functions to get more, etc. What is the reason for the top secret two space newline markdown weirdness? Will a bullet dropped and a bullet fired from a gun horizontally REALLY hit the ground at the same time when air drag is taken into account? How can I count unique selections from multiple selections in a drop down list (Excel) I would like to count the number of unique selections from a column that contains multiple selections from a drop down list.  For example, column B3 contains,     Monday, Tuesday, Wednesday   The count function returns a value of 1 instead of 3 - is there any way to count the three days distinctly? Thank you!  Multiple selections from a drop down list was made possible using the VBA code from: Why does the reputation need to be publicly displayed? Names of close-voters are not visible in the post notice but in the revision history and timeline I am not a user with close/reopen votes privileges on Travel Stack Exchange, therefore I can't see the names of the close voters :    However, they are visible when going to the revision history:    or the timeline of the post:    This also happens when I am not logged in: I cannot see the banner (and so if the question has been closed), but from the revision history/timeline of the post I can get that information.  Shouldn't names of close-voters be completely hidden from people without close/reopen privileges (even if the revision history is a little hard to find)? Delete all files to which no corresponding file with another extension exists My goal is to find a Linux command sequence, which deletes some files if a special condition is fulfilled:  All files with the extensions .cut or .cut.bak in the current directory shall be removed, IF there is no file having the same name, but extension .rec or .mpg in the current directory.  Background: I am developing a tool for a Linux-based PVR, that allows cutting of recorded programs. For each recording (extension .rec or .mpg) the segment markers are stored in a .cut-file with the same name. When some recording gets moved/renamed/deleted, then the corresponding cut-file remains orphaned and shall be deleted. I already have implemented the removing of those useless cut-files in C. But I am wondering, whether there may be a (simple) system based solution. In this case it could be run via 'system' and &amp; in the background, which would make my application more responsive...  I already asked a similar question for the recursive case (browsing also into subdirectories), . There has been a (nearly) perfect answer by kos - but unfortunately it removes too many files, so it is not usable, and I was not able to figure it out... But the same idea can be used here, IF it is possible to parse and pipe the result of 'ls' linewise... Apex compile error : variable does not exist I'm having issues with creating a pretty simple test Utility Class. I want to create two records: an account and a related child contact. The error I see in the developer console is:     Variable does not exist: a.ID   My code, based on the Salesforce Apex Workbook, is as follows.

(Microsoft.SqlServer.SmoExtended) System.Data.SqlClient.SqlError: The database was backed up on a server running version 10.50.1600.

Either restore the database on a server that supports the backup, or use a backup  that is compatible with this server. (Microsoft.SqlServer.Smo)   Is there a way to get a backup which is compatible with the older (in my case 10.00.2531) version from the newer (in my case 10.50.1600) version of SQL Server Express? Removing OS from Dual Boot computer, and recovering HD space. I have a computer that dual boots Linux Mint, and Ubuntu, I am wondering what the best way would be to remove Linux Mint, then recovering the hard drive space that is resides in so that Ubuntu will be able to access it. Vote for Tag Synonyms Directly on the Page Before:  After:   The pros:  Speeds up the tag synonym voting process. Easier to locate (as opposed to navigating to each individual tag wiki page). Encourages users to vote on more than one at a time.  The cons:  Serial up/downvoting. But this really isn't even an issue because, (1) only experienced users can vote on tag synonyms, and (2) more than one vote is required to approve a tag synonym, so the occasional serial up/downvoter won't significantly impact the overall process. Do the Ents go to the Undying Lands? What is the best way to clean lenses and filters? After removing dust with an air pomp and a brush, what are you using to remove stains from the lens and filters?  So far I'm using the liquid from a Giotto's CL 1002 cleaning kit for the lens, but I'm not sure what should I use for the filters, and if there is some better alternative.  Also, what kind of brushes are recommended?
