RE: [GD-Windows] Messed up windows after fullscreen

[Philip T. <pt...@mi...>]

WM_CREATE is a post-notification of window creation. at that point, you =
should be able to use the window handle with other Win32 API calls.

I suspect that is why OGL is initialized during WM_CREATE.

note if for some reason you want to fail the creation of your own =
window, you need to handle WM_NCCREATE, which is the pre-notification of =
window creation. by returning either FALSE or -1 ( cant remember off the =
top of my head, its been a while since I wrote custom controls where =
this can be important ) then you will get an invalid window handle back =
from CreateWindow.

any good introductory Win32 tome should discuss, somewhat, the =
initialization sequence of messages duing window creation. serious =
spelunkers should be familiar with Matt Pietreks' work.
