Re: Window messages

    I am new to Windows programming and have a few questions regarding
Windows with 
DirectX.  I'm using Direct Input to handle mouse and keyboard input, but
have hacked around going through the windows messaging while still doing
tests. The outline of a game loop, from what I gather, is to PeekMessage if
one is present, and handle it, and if not, then go on with your game loop. 
But what Messages do I need to keep the default mouse pointer from
appearing in a fullscreen app.  I do a SetCursor(NULL) to get rid of it
now, but if  I pass it to the DefWindowsProc(), it reappears.  I assume I
need to handle a certain message, but do not know which. Any help would be
appreciated.  In addition to this, if anyone could point me in the
direction of a list of WM messages I am going to need with a fullscreen app
to make Windows happy when various things like multitasking and such happen
I would appreciate it.  I know this list probably consists of quite a few,
but any help is appreciated.

AFAIK, WM_SETCURSOR is a message that is sent just after WM_CREATE, but is
usually passed to the DefWindowProc(). I think that this is a good place to
hide the cursor (and I think that FALSE, i.e. 0, is what it expects, not
NULL, i.e. (void *)0, even if they ultimately do the same thing).

BOOL FAR PASCAL MainWndProc(HWND hWnd, UINT Msg, WPARAM wParam, LPARAM
lParam) {
	if(Msg == WM_SETCURSOR) {
		ShowCursor(FALSE); /* hide cursor */
		. . .
		return TRUE;
	}
	else if(Msg == WM_DESTROY) {
		ShowCursor(TRUE); /* show cursor */
		. . .
		return TRUE;
	}
	. . .
}

With DirectX, it is also important to know when your app is activated and
deactivated, but I'm still hacking my way around that one because I gave up
trying to figure out WM_ACTIVATE and WM_ACTIVATEAPP (for some reason, they
don't seem to work as documented, or at all, on my machine).
