Expose a WinForms UserControl as an ActiveX control

问题

How do you expose an WinForms UserControl written in C# as an ActiveX control? My goal is to then use this UserControl from other languages such as VB6 or Delphi.

回答1:

The solution is to use the Interop Toolkit, see http://msdn.microsoft.com/en-us/vbasic/bb419144 and http://www.codeproject.com/KB/vb-interop/VB6InteropToolkit2.aspx.

回答2:

You will need to create a Runnable Callable Wrapper or COM Callable Wrapper depending on your direction.
