• How to get VS or Xcode warning with something like "x = x++"?

  - by Jim Buck

  In the spirit of undefined behavior associated with sequence points such as “x = ++x” is it really undefined?, how does one get the compiler to complain about such code? Specifically, I am using Visual Studio 2010 and Xcode 4.3.1, the latter for an OSX app, and neither warned me about this. I even cranked up the warnings on VS2010 to "all", and it happily compiled this. (For the record, VS2010's version added 1 to the variable where Xcode's version kept the variable unchanged.)

• WinForm And Looping

  - by Soo

  I have a WinForm set up and a process that loops until a button is pressed on the form. When I try to run my code, the form does not even display. I suspect this is because the code gets stuck in the loop and doesn't get far enough to display the WinForm. How can I get the form to display and the loop to run after that point?

• Escaping ’ character in PHP

  - by richard

  Hello, I'm having a hard time trying to replace this weird right single quote character. I'm using str_replace like this: str_replace("’", '\u1234', $string); It looks like I cannot figure out what character the quote really is. Even when I copy paste it directly from PHPMyAdmin it still doesn't work. Do I have to escape it somehow?

• 'if' in prolog?

  - by jreid9001

  Probably a stupid question, but I can't find any documentation anywhere for it. Is there a way to do an if in prolog, e.g. if a variable is 0, then to do some actions (write text to the terminal). An else isn't even needed, but I can't find any implementation of if.

• TSQL - MSSQL 2008 add a column and update it in same stored procedure

  if I have a stored procedure say create procure w AS ALTER TABLE t ADD x char(1) UPDATE t set x =1 Even when it lets me create that stored procedure (if I create it when x exists), when it runs, there is an error on the UPDATE statement because column x doesn't exist. What's the conventional way to deal with this, it must come up all the time? I can work around it by putting the UPDATE inside EXEC, is there another/better way? Thanks

• Works on development server but it doesn't on Google App Engine (Sessions).

  - by grep

  Hi, I have this code that works just fine on the development server but when I deploy the application, the session isn't created. What am I doing wrong? HttpSession session = req.getSession(true); session.setAttribute("loggedIn", new String("true")); Edit: The sessions are enabled. What I realized now is that the _ah_SESSION variable is not being created, not even on the development server (although it works).

• How do I get this validationTextBox to focus?

  - by Anurag Chaudhury

  After performing an ajax request if the input in the form was wrong I am trying to get this validatationTextBox to be focussed on and display an indicator message showing the problem. The code is: dijit.byId("passwordField").focusNode.focus() The form element is as mentioned a validationTextBox. The matter that is confusing me even further is that before in dojo 1.5, this piece of code was simply dijit.byId("passwordField").focus() and this worked fine. How can I fix this?
