Right, if hInstance is derived from the controlParent then of course
hInstance will always be the same. In addition, you bypass the HWND-child RB
has already created for you. You may want to use this HWND-child to obtain
the hInstance, instead of the hwnd from the REALwindow.

Thus:

 HINSTANCE hinstance =
     (HINSTANCE)GetWindowLong(REALGetControlHWND(instance), GWL_HINSTANCE);

winRwf = REALgetControlHandle(instance);
                   
wHwnd = CreateWindowEx( 0,
                "SysDateTimePick32",
                0, 
                WS_CHILD + WS_BORDER + WS_VISIBLE,
                0, 
                0, 
                rect.right - rect.left,
                rect.bottom - rect.top,
                winRef,
                0, 
                hInstHandle,
                0
                 );

Now your wHwnd lives on the controlHWND and not on the REALwindow,

Alfred
