Problems registering assembly for COM


P

Phil

VB2005
I have created a class library project.
I have created a class using the COM class template.
In the Application tab under My projects if I click on Assembly Information,
the 'Make assembly COM-visible' box is checked.
In the Compile tab the 'Register for COM Interop box is checked.
In the Signing tab the 'Sign the assembly' box is checked, and I have
created a .snk file.
The Delay sign only box is not checked.
I have built the project and checked that I can reference and use it from
VBA project on my machine.
I have copied the dll onto another machine and issued the following command:

regasm mydll.dll /tlb:mydll.tlb /codebase

This appears to run successfully.

When I try to use the dll from a VBA project on this machine, I can add the
reference OK, and it shows up in the object browser, but when the code runs
I get an error saying that the assembly or one of it's dependencies cannot
be found.

Any ideas?
TIA
Phil.

Hi Phil,

Based on my experience, such error is usually caused by some dependent
assemblies cannot be loaded by your assembly. You can either use Reflector
(http://www.aisto.com/roeder/dotnet/) to open your assembly and see which
referenced assemblies are missing or you can use Assembly Binding Log
Viewer (fuslogvw.exe)
(http://msdn2.microsoft.com/en-us/library/e74a18c4(VS.80).aspx) to know
which assemblies are failing to load.

Hope this helps.

Thanks, There shouldn't be any dependencies other than the standard VB
runtime stuff, as I haven't added any references in this project. Other VB
applications have been installed on that machine in the past, so I assumed
everything needed would all be there already.
I expect if I build a proper deployment package it will work, but this was
just a quick test to see if I can access some of my code from VBA. It would
have been much easier and quicker to simply recompile my code in VB6, but I
shall persevere with the new more complicated ways of doing the simple
things in .NET.

Cheers,
Phil.

Have you tried the Assembly Binding Log Viewer, maybe it could give us some
clue.
