How can a method used in a VB client connecting to an VB 5.0 Automation server get back a changed parameter?
I defined e.g. in the  Server where Version is passed ByRef:
Public Function GetVersion( Version As String) As Long
  .. changes Version  ...
call in the Client:
MyAppl.GetVersion ( Version )

but Version is not changed !

Hi Philip

The problem is in your calling convention.

The MyAppl.GetVersion(Version) is passing the parameter By value even though your function declares it By Reference.
Change the call to either "MyAppl.GetVersion Version" or "Call MyAppl.GetVersion(Version)"
