I have a situation where I want to show/hide my SharePoint list column / Fields in a list form based on the value of some other field on the form.   Example :  I have 2 dropdowns say "IssueType", "Level" and a TextBox, I want that my TextBox should be visible only when value from dropdowns are "Error" and "High" respectively.  How can I achieve this in the form?  I am OK with using JS, CSR or any other option available as this is for my own learning purpose.
I need to hide field 'B' when the value in field 'A' is NOT equal to 'Other'.  This is a custom list form.  Is jquery the way to go?
ResultSet: Retrieving column values by index versus retrieving by label When using JDBC, I often come across constructs like    ResultSet rs = ps.executeQuery(); while (rs.next()) {     int id = rs.getInt(1);     // Some other actions }   I asked myself (and authors of code too) why not to use labels for retrieving column values:    int id = rs.getInt("CUSTOMER_ID");   The best explanation I've heard is something concerning performance. But actually, does it make processing extremely fast? I don't believe so, though I have never performed measurements. Even if retrieving by label would be a bit slower, nevertheless, it provide better readability and flexibility, in my opinion. So could someone give me good explanation of avoiding to retrieve column values by column index instead of column label? What are pros and cons of both approaches (maybe, concerning certain DBMS)? In H. P. Lovecraft's The Case of Charles Dexter Ward, Dr. Willett      Enters Joseph Curwen's dungeon and resurrects a dead person identified as No. 118 by reciting the incantation of the Ascending Node over his salts.   Dr. Willett is told by      The resurrected Joseph Curwen, impersonating Charles Dexter Ward, who he secretly murdered,   that   " 'twas Number 118, and I conceive you would have shook had you looked it up in my list in t'other room."  No. 118 himself gives Dr. Willett a note asking the doctor to      kill Joseph Curwen.   It soon becomes clear that No. 118 is opposed to the nefarious dealings that have been transpiring and desirous of being an ally of Dr. Willett.  Who is No. 118?  Earlier in the story,      The grave of Ezra Weeden, a primary instigator in Joseph Curwen's initial downfall and the romantic rival of Curwen, is robbed. There doesn't seem to be any other mention of Weeden in the 20th century occurrences, so without a further connection the passage seems superfluous.   The shared goals of these two people seem to indicate that No. 118 may, in fact, have been that person, but the      Note given by No. 118 to Dr. Willett in eighth century Latin seems to indicate someone much older than Ezra Weeden.   It also occurred to me that No. 118 could be      The recently murdered Charles Dexter Ward himself. Ward's reference to killing Dr. Allen (who is actually an alias of Curwen) and dissolving his body with acid and No. 118's mention of doing the same to Curwen seem to support the idea, but that still doesn't explain the archaic note. Ward is described as writing in a somewhat modern style, at least as opposed to Curwen. It also doesn't explain why Curwen would want to murder Ward if he was going to resurrect him later anyway. (Ubuntu/Linux)"find" command gives different results based on quotation marks I was using   find -iname *prib*   and getting only one result "./prib09jack.pdf" with   find -iname "*prib*"    I get many more results that I was looking for such as  ./Dir1/PRIB09/prib09jackTFF1.pdf   and many more, but why did it matter that the quotation marks were around "prib"?

Yes, this is a pedagogical question. While answering another recent question, I wanted to refer the OP to concise instructions for using superposition to solve circuits. I found that all the easily found resources online were somewhat deficient. Typically they were unclear about what kinds of circuits superposition applies to, or about the actual method to apply the superposition theorem to a circuit problem. So,   What kinds of circuits can be solved by superposition?  How are different kinds of sources treated when solving by superposition?  What are the steps to solve a circuit using the superposition theorem? What is the likelihood of ever discovering the graviton? How would one look for and confirm existence of a graviton?  Someone was speaking to me about perhaps one day discovering the graviton, but to me it seems unlikely, although I'm young and essentially quite naive, so am coming to you physicists to ask    What actually is the likelihood of finding it?  How would we find it? Is this an equivalent formulation of "surjective" resp. "epimorphism"? Is it correct to omit preposition before date? Way to play shared game that is in use in steam?

TikZ Adding Text I'm a recent convert to TikZ from xy-pic, and am still trying to get a hang for it. I see that one can add labels to the end of arrows and the like using \node.
