VB6: How to create a DLL and use it in C#?

Question

Using a VB6 Class in C#

I have a serialization egnine written in VB6, which makes binary serialization in some mysterious way I didn't get to figure out. I also have a C# program that needs to make serialization the same way the VB6 code does.

So I wanted to make the VB6 serialization code in DLL and use it in the C# program so that the binary serialization would fit. How can I do that?

VB6 classes are COM objects, and C# can use them via COM-interop.

Set your VB project to build an in-process COM server, then add it to the C# project as a COM reference.

What did you mean by saying "an in-process COM server"? what does it have to do with server and how do I do that? Sorry but I didn't understand so well, and I'm new to this. Thanks! – Giora Ron Genender Sep 03 '11 at 03:18
@Giora: It's a setting in your VB6 project properties. – Ben Voigt Sep 03 '11 at 03:52
