Hi Sunny,
Thank you again and again for helping me, but this time I could not score
with your tip. First I thought, to put the assembly to the GAC would solve
the problem, but the Exception was the same. I did the following:
1. I createt a key pair to get a strong name for the assembly
2. I added the attribute "[assembly:AssemblyKeyFileAttribute(keyFileName)]"
to the struct code
3. I added the assembly to the GAC by using the .NET Framework Configuration
Tool
4. (Here I was not realy sure!) I added a refference to the lokal
(ProjectFolder) stored assembly
I'm not sure, how to reference an assembly placed in the GAC, but I could
not find any other assembly as this one in my ProjectFolder.
Ok, this didn't work, then I wanted to try your tip No. 2, but I could not
find any AppDomain-Object out of my AddIn-File. There I have only a
Microsoft.Office.Interop.Word.Application-Object, but there is no AppDomain
in view. Can you tell me, how to get it out of the OnConnection-Method of my
AddIn?
I hope not to bore you :-)
Thank you and Regards,
Kai
