How to create ActiveX DLL in Visual C++

Question

Is there a tutorial/reference for creating an ActiveX DLL in Visual Studio 2008 C++ ?

I've got a DLL built with the DLLRegisterServer/UnregisterServer, and it's registered, but I'm having a little trouble figuring out what name to use to reference it (from a vbscript) and how to make sure my functions are exported correctly. Do I have to put my functions in a special class?

Thanks!

Answer 1

There are a lot of details to get right. Best thing to do is to use ATL and the built-in ATL object wizard. It auto-generates a bunch of files so that the IDL, type library, registration script, class wrapper and event proxies are all done correctly.

Answer 2

The component's ProgID is normally defined in the project's .rgs file.

Visual Studio contains OleView.exe. You can open your dll from it and see the list of props and methods.
