Changing XML file datasource location in VB.NET

[crisedefoie]

HI

I created a Crystal Report which datasource is a XML file.
This file will be created and destroyed so I have to specify the location of the XML filewith each treatment.

There is my code :

lTblReport = Report.Database.Tables
For i = 0 To lTblReport.Count - 1
Report.Database.Tables(lTblReport.Item(i).Name).Location _
= CurDir() & "\" & XMLFileName
Next

Report.ReportSource = CReportName
etc...

There is the error message I got when it met the instructions in the FOR statement :

Error in 'ReportName'
Incorrect key number

I tought that's a very easy way to change file location but ... Where did I go wrong?

Thank you!
