Question

How can I prevent DDE TimeOut messages when launching ArcView GIS 3.x from a Visual Basic application?

Answer

Set the LinkTimeOut property of the Visual Basic control to allow time for ArcView GIS to initialize. For example,

theControl.LinkTimeOut = 600.

This allows 60 seconds for ArcView GIS to start.
