Title: Error Using .NET Add-ins
Post by: charge on October 08, 2004, 02:24:20 am

There is no variant type in .NET

When I create an add-in in VB.NET I have to implement the interface EA_GetMenuItems(....) as Variant in a COM class

Until version 4.10.737 I used string() as returntype. In version 4.10.738 it does no longer work.

Any suggestions to fix this problem???

The likely reason for this error is that they have improved the interface to .net, and are now providing a strongly typed assembly: Interop.EA.dll.

You should de-reference EA in your VS project, and reference Interop.EA.dll from \program files\sparx systems\ea.

The interop file you compile with should also be included with your installations.

Hi,

Have you tried using 'object' as your return type?

Cheers

using 'object' as return type doesn't fix the problem. You should use the  Interop.EA.dll from EA and then it works fine !
