Device->SetDialogBoxMode(true);

for some reason i am unable to see any child windows if i call this device member , in msdn it cleary says i should be able to view gdi windows on the device , i have all the param settings set


d3dpp.SwapEffect = D3DSWAPEFFECT_DISCARD;
d3dpp.Flags=D3DPRESENTFLAG_LOCKABLE_BACKBUFFER;
d3dpp.BackBufferFormat = D3DFMT_X8R8G8B8;

in wndproc i have

Code:

case WM_CREATE:
			
	    hmodule = GetModuleHandle(0);

		Child = CreateWindowEx(NULL,
                          "BUTTON",
                          "test",
                          WS_CHILD | WS_VISIBLE ,
                          40,30,
                          50, 60,
                          hWnd,
                          NULL,
                          hmodule,
                          NULL);
		break;

That may only apply to dialog boxes. I would not recommend mixing GDI windows with Direct3D.
