Hi, just did that yesterday:

1. In VB -> new project -> ActiveX DLL
2. Name the Project (lets say "MyLibrary")
3. Name the ClassModule (lets say "Functions") and set Instancing to MultiUse
4. Write your functions, Public Functions will be accessible (lets say Public MyFunction(Param))
5. Compile and Save your DLL (lets say to "C:\MyLibrary.dll")
6. Goto Start->Run-> "regsvr32 C:\MyLibrary.dll" (the DLL is registred in Windows no, to unregister run "regsvr32 -u C:\MyLibrary.dll")
7. Use it like:
Dim Object
Set Object = CreateObject("MyLibrary.Functions")
