UserControl
 

I think I'm going a bid mad.

I've acquired an Excel Application and Opened a Workbook within it (from C#).

I then execute the code

xlApp.Visible = true ;
xlApp.UserControl = true ;

The correct workbook displays for about 3-5 seconds, then closes. For the
life of me, I can't understand why.

Desperately, anyone have any suggestions ?
