Thread: Unable to change the windows background color

Hi there,

well I'll just get to the point:
I tried two methods,

Code:

SetClassLong(hwnd, GCL_HBRBACKGROUND, (LONG)CreateSolidBrush(RGB(255,255,255)));
InvalidateRect(hwnd,0,TRUE);

and

Code:

case WM_ERASEBKGND:
{
	HDC hdc;
	RECT rc;
	hdc = (HDC)wParam;
	GetClientRect(hwnd,&rc);
	FillRect(hdc,&rc,(HBRUSH)CreateSolidBrush(RGB(255,255,255)));
	return 0;
}

Both methods leave my client area windows-grayish, also when I refresh/update/redraw the window.

I use CreateDialog with resources to create my window handle.

Code:

STYLE DS_CENTER | WS_MINIMIZEBOX | WS_POPUP | WS_CAPTION | WS_SYSMENU | DS_3DLOOK
EXSTYLE WS_EX_APPWINDOW

Maybe I just forgot a style needed to change background? Can anyone give advice? Tell me if you need the full code.

Thanks in advance, Hawk.

This page might help [URL="http://www.winprog.org/tutorial/dlgfaq.html"]. I prefer to not to use resources as they prevent the window from being able to resize, even though the background colour defaults to white.

Thanks, this method works

I don't think I can change my style of creating windows, because I've gotten used to it and it's still the fastest way to add stuff to my programs...

I just set the WS_THICKFRAME style and had to notice that my code in WM_PAINT stopped BitBlt-ing. Well I need to find a way around that when I come to writing a program which profits from being able to be resized.
