Register DLL for COM interop

I am trying to create a vb6 activeX dll in .Net. I used the upgrade wizard in
vs.net to load my vb6 project and it converted it to vb.net. Now I know that
I have to register the DLL from COM interop. I can check the box in vs.net on
the compiler tab to do this.

But how do I register my DLL for COM interop on another machine?

Hi Philip,

I think you may try to use the Regasm tool, which will do the job just as
the IDE do.
Assembly Registration Tool (Regasm.exe)
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cptools/htm
l/cpgrfAssemblyRegistrationToolRegasmexe.asp

Hi Philip,

Technically speaking, you can´t create VB6 ActiveX dlls in .NET. You can
create DLLs using VB.NET / C# that can behave as ActiveX components using
COM Interop.

You have several options:

- Manually you can use the command-line regasm.exe utility, likely with the
/codebase switch. Check the docs about this.

- Programatically you can use the
System.RunTime.InteropServices.RegistrationServices class, using the
RegisterAssembly function, for example.

- If your setup technology is aware of registration of .NET assemblies for
COM Interop, you should instruct the setup to do this.

Can I instruct the Setup project template in vs.net 2005 to register it?

Yes. In your setup project, just set "Register" property for your DLL
file to something containing COM. See
http://msdn2.microsoft.com/en-US/library/z5s1e2wh.aspx for more details.
