Hi I am Tarun Mangukiya And I had a same problem in May, 2010.
So. I Solved it as below.
Use This Code
Add this line above the
Class Form1
<br />
Imports CrystalDecisions.CrystalReports.Engine<br />
Imports CrystalDecisions.Shared<br />
Then Add this line to your Report On load code
<br />
Dim report As New ReportDocument()<br />
Dim connection As IConnectionInfo<br />
Dim server As String = Application.StartupPath & "\Data.mdb"<br />
report.Load(Application.StartupPath & "\MYReport.rpt")<br />
CrystalReportViewer1.ReportSource = report<br />
For Each connection In report.DataSourceConnections<br />
report.DataSourceConnections(connection.ServerName, connection.DatabaseName).SetConnection(server, "", "", "")<br />
Next<br />
And Your Problem will be solved.
Thank you. :)
