Just been following the d3d9 tutorial from here: http://www.gamedev.net/reference/articles/article1943.asp and compiled it, it all runs and the window is created but after about a second the window is destroyed and the only output in the debug window is:


Direct3D9: (ERROR) :    [0] : Address 00A3D4CB

Direct3D9: (ERROR) :    [15] : Address 00000000

any ideas on what this could be?

Those errors refer to memory that has not been deallocated correctly. But it gives no clue to why your program is exiting prematurely. Maybe you could post some of the code. The main loop perhaps.

You should have a ShowWindow call after you create the window methinks.

Also, try to put long segments of code into [ code] tags. It makes it a bit easier to read your code.

Just tried ShowWindow and it makes no difference the window is stil created and displayed and then suddenly destroyed?

if(Msg.message = WM_QUIT)

Your loop breaks right away because you're assigning WM_QUIT to Msg.message. You want ==.

Hmm.. you have a return in your while-loop. That would cause your WinMain to exit and is probably the answer to why the window just gets created and destoryed. Try to remove it and I think it should work fine.

	while(1)	{		PeekMessage(&Msg, hWnd, NULL, NULL, PM_REMOVE);		if(Msg.message = WM_QUIT)			break;		else		{			Render();			TranslateMessage(&Msg);			DispatchMessage(&Msg);		}		HERE >>> return ((int)Msg.wParam); <<< HERE	}

That's true too.

excellent thankyou i cant belived i overlooked thoes lol. so that problem is fixed but i have a new error.

now when it runs it comes up with unhandled exception at 0x00411608 in dx_render.exe

and is identifying this line:

	pD3DDevice9->Clear(0, NULL, D3DCLEAR_TARGET, D3DCOLOR_XRGB(0, 0, 255), 1.0f, 0);

That line's correct. The only thing I've done differently was cleared the zbuffer in addition to the target, but that shouldn't affect anything.

Not related to the crash, but remove the hWnd from the PeekMessage call. You will not receive WM_QUIT if you leave it in there.

WM_QUIT is posted to your thread's message queue, not to any particular window.
