Question

I’m trying to implement an interface in VB6. I have defined the class Cast_Speed like this…

Public Function Run_Time() As Long

End Function

and the implementation like this…

Option Explicit
Implements Cast_Speed

Public Function Cast_Speed_Run_Time() As Long
    Cast_Speed_Run_Time = 0
End Function

but attempting to compile it gives ‘object module needs to implement ‘Run_Time’ for interface ‘Cast_Speed’. Can anyone see what I am doing wrong? My subroutines seem to be quite all right, but all the functions I try have this problem.

Answer 1

It doesn’t like the underscore character in the method name. Try using RunTime() instead.

I just tested it without the underscore and it works fine for me:

'// class Cast_Speed
Option Explicit

Public Function RunTime() As Long

End Function


'// class Class1
Option Explicit

Implements Cast_Speed

Public Function Cast_Speed_RunTime() As Long
  Cast_Speed_RunTime = 0
End Function
