[resolved] Making Active X Compatible DLL with C#

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 :cry: I supposed that would be too obvious. :rolleyes:

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

Code:

---

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

---

Modify the ComVisible property in the actual assembly file itself

Code:

---

//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 :sick:
