Building an OCX with VS.NET?

What happened to OCX's? Are they no longer possible to create with the latest tools?

I need to create an ActiveX control that I can place in Word, PowerPoint and Excel documents. If I use VS.NET, I can only create a UserControl DLL with COM Interop, but I don't think I can add that using the "More Controls" toolbox of PowerPoint's Developer Tab.

What would you do?

Solution

  • Yes, you can still create them. But you can't create an OCX with a .NET language. Need to be unmanaged C++ (or VB). The DLLs with COM interop you can create in C# or VB.NET are just .NET objects that are invoked via CCW.
