Translate VB code into VC++

This is simple: I want a VB6 ActiveX DLL Project to be re-written using Visual Studio 6. The DLL\\\'s main function is to encrypt/decrypt a text into hexadecimal. The crypting code is actually in [login to view URL], Microsoft encryption library and the DLL is barely a wrapper. Only specificity is that the DLL implements an interface and this must be replicated in the VC++ code. This is a first VB project out of a series. If I am happy with the work on this small task, there will be more to follow.
