I had a similar problem that was solved with the API.<br>
<br>
Declartaion:<br>
<br>
Private Declare Function ShowWindow Lib _<br>
"user32" (ByVal hWnd As Long, ByVal nCmdShow As Long) As Long<br>
<br>
to hide it:<br>
Call ShowWindow(UserControl.hWnd, 0)<br>
<br>
to show it:<br>
Call ShowWindow(UserControl.hWnd, 1)<br>
