developing a .net - activex control for visio

[Purrer Wolfgang]

I try to develop a activex Control which in can use in visio.

I already managed to create an activex control with c#. But when
insert this control the following message appears:


An Error (1442) occured during the action Insert Control.
Visio cannon insert this control because its TypeInfo did not merge
correctly. Ensure all parameter types are VBA freindly. Delete Temp
*.exd
file if necassary.

Does someone have a idea what to do.. i didn't find an answer through
google!

Got an answer from Microsoft Suppoert => in short it is not not
possible (or only with a lot of troubles)


Description of the supportability of Winforms controls in unmanaged
applications http://support.microsoft.com/kb/897863/en-us

Some research within our databases has shown that .NET Framework
controls can only be embedded in containers, which explicitly support
them, like Internet Explorer or MFC.

ActiveX control containers that support .NET controls

If this is not the case, then problems will arise in the following
areas:
- Keyboard handling, tab-order, window activation, function keys,
accelerators.
- Threading, apartments and global objects.


Alternative Solutions:
- Host the control within Internet Explorer.
- Create a MFC wrapper control.
