I have already run in this problem (this is the reason why I thrashed VB 
and now use GTK+ :-); the problem is in the different use of strings 
between VB and C. A workaround that worked for me is the following:

1. change your library function to:
      void _stdcall reportTime (char ** name)

2. change your function declaration to:
      Private Declare Sub reportTime Lib "your.dll"
                               (ByRef name As String)
