Solution 1

There's really no path from C# to VB6. Tell your friend VB6 has been obsolete for 20 years now, there's no reason to learn or use it.

There's a lot of online converters, see: Google[^]

Any way, i do not recommend to convert anything to VB. As Christian Graus[^] mentioned this programming language is very old and almost useless these days. There's no even chance to compare these languages. If your friend knows VB, he can use VB.NET. This might be good place to start: Hook Unmanaged Processes Using VB.NET DLLs[^]
