| | I just added a pause button to my game, using most of this code: [URL="http://msdn.microsoft.com/en-us/library/bb195026%28v=xnagamestudio.31%29.aspx"]http://msdn.microsoft.com/en-us/library/bb195026%28v=xnagamestudio.31%29.aspx[/URL] For some reason it changes the Window.Title to "[GameName] - Paused" and even though it's unpaused it still says paused in the title.

| | I have a web project I've been working on in my free time using mostly jsp. It's currently set up so that if a user clicks the login button it takes them to a check-login servlet which will return whether it's a valid login or not through a session.setAttribute("loginstatus","Valid").

| | I keep getting the IndexOutOfRangeException for my XNA game and after printing the indexes it stops at 600. Is that the max limit for arrays in C#? I'm trying to get all of the pixels from an 800x600 image into an array so I can test when a R:20 G:20 …  |

| | Re: For loops 4. Outputs all the numbers that when squared are between 1 and 10. So if firstNum is greater than 3 there won't be any numbers that when squared are between 1 and 10. for (int i=0; i<totalnumbers; i++){ squarednumber = number*number; if ((squarednumber>=1) && (squarednumber<=10)){ System.out.println(squarednumber); } } |

| | NetBeans or Eclipse. I use Eclipse and love it. I'm assuming you can understand the basics and just don't know java's capabilities and syntax. If you really want to jump straight into GUIs, do a google search for "java layouts" and "java swing." |
