HWND - Unable to read memory

Renthalkx97 (152)
So I'm working with DirectX 11 and for some reason the debugger is telling me that the memory of my HWND is unreadable. I've even used the Win32 template from Visual Studio and it's still unable to read the memory. This is problematic because my DirectX class constructor takes a HWND as a parameter to set up the swapchain and the CreateDeviceAndSwapChain function fails because of that.

Here's my code to create the window:

	MSG msg;

	ZeroMemory(&msg, sizeof(msg));
	while(msg.message != WM_QUIT)
	{
		if(PeekMessage(&msg, NULL, 0, 0, PM_REMOVE))
		{
			TranslateMessage(&msg);
			DispatchMessage(&msg);
		}
		else

		}
	}
}

LRESULT CALLBACK WndProc(HWND hWnd, UINT msg, WPARAM wParam, LPARAM lParam)
{
	switch(msg)
	{
		case WM_DESTROY:
			PostQuitMessage(0);
			break;
	}

	return DefWindowProc(hWnd, msg, wParam, lParam);
}


EDIT: Fixed the problem. I forgot to set the buffer format. And I thought the HWND was causing the problem but I did some research and it turns out that's the normal value for it.
