Question

I have my script on server, so I do not have UI interaction available and have to use DLL instead of console application.

How to call a function in C# DLL from VBScript?

How do I make my DLL to be COMVisible? Do I have to register it?

Answer 1

You need to mark your assembly as COM visible by setting the COMVisibleAttribute to true (either at assembly level or at class level if you want to expose only a single type).

Next you register it with:

regasm /codebase MyAssembly.dll 

and finally call it from VBScript:

dim myObj Set myObj = CreateObject('MyNamespace.MyObject')
