We are using a system that allows ActiveX extensions through .ocx files.

I need to write an extension to plot some specific proprietary graphics. After lots of searches, I found out Visual Basic 6.0 can create these ActiveX controls and deploy them as .ocx files.

So, is VB6 the only option? I’m reluctant to believe no other options have been introduced by microsoft since 1998.

In response to RichieHindle and Arnshea,

During the research, I found out ActiveX controls might be created using C++, but I couldn’t find a way to deploy them as .ocx files. Just as dll’s.

    You can create ActiveX controls in C++ using Visual Studio 2005 or 2008, via ATL or MFC. There are wizards to help – the process is relatively painless. 😎

    An OCX is a DLL – it’s exactly the same, just with a different file extension. (Pedant’s corner: I know the inverse is not true; not all DLLs are ActiveX controls.)
