DialogBox trouble

**Sevko** · 01-10-2011

Hi, my app uses Dialog boxes for new gamae, changing settings and etc. But the problem is that while they work fine on my computer and on my friends(we all sue win 7) it doesn't work in school(they use win xp). It only works on 4 computers which aren't setup according to the schools settings. The app runs fine playing the game but when it comes to a part that uses a DialogBox the app froze(doesn't crash or anything no error mesages from windows). So what could the problem be?

Check your code... make sure there are no calls or controls in the dialog that are not supported on XP. (Win7 introduced some new stuff). Looking the items up in the SDK will tell you which versions are supported.

I have alot of diffrent dialogs. But none have things that shouldn't be supported in XP. It worked on one computer which has XP OS. I added WS_VISIBLE to all and ShowWindow in the dialogs. If it still won't work I'll just disable win XP visual styles.

Ok the pushbuttons and radiobuttons should be a problem... but you might want to check the LTEXT against the SDK...

Another way to test it is to run your program in XP compatibility mode on the win7 machines and see what messes up.
