[resolved] Making Active X Compatible DLL with C#

[umilmi81]

Does anyone know how to make a C# DLL reverse compatible with Active X? I want my C# class to be used in VB6. I know it's theoretically possible, but it's not working for me.

I checked the "Register for COM Interop" box in the build properties, but it didn't work I supposed that would be too obvious.

I'm using VS2005.

I solved this myself.

Steps are as follows:

Include special tag to indicate class interface in front of the class definition

[ClassInterface(ClassInterfaceType.AutoDual)]
    public class YourClassName
    {
        //Your Code
    }

Modify the ComVisible property in the actual assembly file itself

//Orginally set to false
//[assembly: ComVisible(false)]
[assembly: ComVisible(true)]

Finally, check the "Register for COM Interop" option in the build properties of the project.

Couldn't be easier
