You can set the visible property of a window to false
w_window.visble = false
To keep the window visible but not in the task bar, define the external function
FUNCTION ulong SetWindowLongA( ulong hWnd, int nIndex, long newValue ) & LIBRARY "USER32.DLL"
long ll_rc ll_rc = SetWindowLongA(Handle(This), -20, 128) IF ll_rc = 0 THEN // something wrong on the kingdom! END IF
