WS_CLIPSIBLINGS and WS_CLIPCHILDREN

[ARES]

are WS_CLIPSIBLINGS and WS_CLIPCHILDREN realy required window styles for an openGL window? I don't use them but I always see that they are required.

YES, you need WS_POPUP | WS_CLIPCHILDREN | WS_CLIPSIBLINGS, //==Windows style
really, you need them also wenn you write a fullscreen app.
Maybe you should look at the MSDN !!!

I never use them for fullscreen or windowed and my app works just fine. So why would you need them.

Here is a little piece of my Code:

//Window Init
hWnd = CreateWindow(
"ByteZero 23", //CLASS NAME
"ByteZero 23", //Window Name
WS_POPUP | WS_CLIPCHILDREN | WS_CLIPSIBLINGS, //Windows style
0, 0, //Origin of the SCREEN
SCREEN_WIDTH, SCREEN_HEIGHT, //Dimension of the Screen
NULL,
NULL,
hInstance,
NULL);

The WS_ .... Stuff is just for the Windows Style if you don't use it in this Function you get Errors !!!!
Maybe some appz work without WS_ .... Stuff but I 've never tried it.

I haven't had an error with my windowed app and I tested it on 3 different pc's.
only the fullscreen only worked at 1 pc.

I don't know what's happen with your Code please send me your code.
I will try to find the problem !!!
