Thread: AdjustWindowRect

I want the client area to be 320 x 240.
Not the whole window.

Now, here is my code.

Code:

HWND WinClass::Create ( HINSTANCE hInstance, LPSTR class_name, LPSTR wnd_name, HWND parent,
					    DWORD dwStyle, int x, int y, int width, int height )
{

	RECT rect = { 0, 0, width, height };
	AdjustWindowRect ( &rect, dwStyle, true );
	
	hWnd = CreateWindow ( class_name, wnd_name, dwStyle, x, y, width, height,
						  parent, NULL, hInstance, NULL );


	return hWnd;

}

Isnt this the correct way to makesure your "client" area is the desired resolution?

You get the rect needed but don't use it.

>>CreateWindow ( class_name, wnd_name, dwStyle, x, y, width, height,

should be

CreateWindow ( class_name, wnd_name, dwStyle, rect.left, rect.top,rect.right-rect.left,rect.bottom-rect.top,

(as the top and left may not be zero)

edit
try
AdjustWindowRect(&rect, GetWindowLong(hWnd,GWL_STYLE), TRUE);
