Rendering to a Child Window w/ D3D & Win32

Hey Guys,

Hoping there are some Win32 guys out there since I have a bit of an issue. So I'm rendering to a child window of my Win32 application with D3D11. For the most part, everything is well, and good. However when I go to actually render some geometry to the screen my backbuffer flashes. At first I thought it was Z-Fighting, however having ruled that out, it almost looks as if there are two presents going on.

The one that I know about, the call to the swapChains method to present the backbuffer, and another one buried in Win32 callback code somewhere. I'm wondering if there is a simple fix for this. I don't need the application to run at anything more than 20fps to be completely honest. So throw some suggestions at me, if ya got them.

The child window I render to:

hPanel = CreateWindowEx(NULL, L"RR", L"None", WS_CHILD | WS_VISIBLE | WS_CLIPSIBLINGS, 40, 20, 500, 500, hWnd, nullptr, nullptr, nullptr);

LRESULT CALLBACK WndProc(HWND hWnd, UINT message, WPARAM wParam, LPARAM lParam)
{
	switch (message)
	{
	case WM_DESTROY:
		PostQuitMessage(0);
		break;
	case WM_COMMAND:
		switch (LOWORD(wParam))
		{
		case IDC_BUTTON1:
			//If Button pressed, retrieve text from textArea, and locate it in wide string
			text.resize(GetWindowTextLength(hEdit)+1);
			GetWindowText(hEdit, &text[0], text.size());
			SetWindowText(hEdit, L"");
			break;
		}
		break;
	case WM_PAINT:
		break;
	default:
		return DefWindowProc(hWnd, message, wParam, lParam);
	}

	return 0;
}

I'm a bit of a Win32 noob. One common suggestion I see is to throw the D3D rendering code into WM_PAINT case, but I was wondering if there are other ways.

Thanks,

Marcus
