Dig into GetHWND code, you will see that a Ctrl need to be top and no parent and be created to have non-null HWND.

In you case, if you call a Open() to have it created before calling to GetHWND(), you have a better chance to get what you want.


GUI_APP_MAIN
{
	MyApp a;
	DUMP(a.GetHWND());
	a.Open();
	a.Hide(); // call this if you don't want the window actually opened
	DUMP(a.GetHWND());
	
	
	a.Sizeable().MinimizeBox().MaximizeBox().Run();
}

Output

a.GetHWND() = 0x00000000
a.GetHWND() = 0x000402d8

HTH,
