"Unspecified Error" placing DrawingControl on a form

[Vic Spainhower]

Hello,

I'm re-posting this message in hopes of getting a reply. I have a 30-day
Visio Evaluation kit which now only has about 2 weeks left. I'm creating a
VB6 app and using the DrawingControl. However, as soon as I place the
control on the form I get "Unspecified Error" and I'm unable to add the
control to the form. I've uninstalled/Re-installed which did not help.

Any ideas?

Vic

Try placing the control on the form via code.

I've had many problems with the visio control disappearing from the (VS.NET)
designer after weeks of coding. You then have to go in and re-add the
control, wondering all the time which code you've broken.

So what I did was write a wrapper class that adds the visio control to a
Panel control at startup. It's a strategy primarily aimed at .NET, but it
might work for your VB6 problems too.
