Hello!
The example is somewhat outdated, the program's name is now feeder8, so it should read:
Sub Back(marketID As Long, selectionID As Long, price As Double, amount As Double, handicapID as Long)
 Dim feed As Integer
 Dim data As String
 feed = Application.DDEInitiate("FEEDER8", "betting")
 If feed > 0 Then
 data = "back/" & marketID & "/" & selectionID & "/" & price & "/" & amount & "/" & handicapID
 Range("AB1000") = data
 Application.DDEPoke feed, "bet", Range("AB1000")
 End If
 End Sub
Is it specifically the VBA code that you need to execute, or do you simply need to collect some information from Excel and process it in MF Pro?
