    Hi Guys,
    I am trying to re direct the DataFlex sourced crystal reports to use a SQL connection using DataFlex 18.2

    Starting with Hans van de Laar Code from and calling it from Procedure OnInitializeReport
    I get the location and login box for the files.

    Click image for larger version.

    What am I missing our here?
    Where should I have connections.ini or ConnectionIds.Ini located?

       Set pbAutoLocateDFFiles to False
       //Hans van de Laar Code
       Procedure InitializeODBConnection Handle hoReport
          Boolean bAttached 
          Handle hoConnectionProperties 
          Variant vConnectionProperties 
          String sTable 
          Integer iTableItem iTableCount
          Handle[] hoTables
          Handle hoDatabaseTable
          Boolean bOk
          Get TableObjects of hoReport to hoTables
          Move (SizeOfArray(hoTables)) to iTableCount
          For iTableItem from 0 to (iTableCount-1)
             Get ComName of hoTables[iTableItem] to sTable
             Get GetTableObjectByName of hoReport sTable to hoDatabaseTable
             Move (hoDatabaseTable) to bOk
             If bOk Begin
                Get create U_cCrystalConnectionProperties to hoConnectionProperties
