[RESOLVED] Crystal reports - Pass parameters and change connection string

Hello guys,

I have a report which datasource is a stored procedure in a SQL2005 database. I designed the report with a parameter value as an example to view results. Now I need to send the parameter programmatically and also I need to change the connection string for the report to connect with the database.

Thanks!! :wave:

Hope this help:

VB Code:

Dim rpt As New crpYourReport
        rpt.PrintOptions.PaperOrientation = PaperOrientation.Landscape
        Try
            Dim rptViewer As New frmReport
            rpt.SetDataSource(mydataset.Tables(TBL_NAME))
            rptViewer.crpViewer.ReportSource = rpt
 
            Dim paramFields As New ParameterFields
            Dim paramField As New ParameterField
            Dim discreteVal As New ParameterDiscreteValue
            paramField.ParameterFieldName = "paramname"
            discreteVal.Value = modGeneral.strCompanyName
            paramField.CurrentValues.Add(discreteVal)
            paramFields.Add(paramField)
 
            rptViewer.crpViewer.ParameterFieldInfo = paramFields
 
            rptViewer.crpViewer.Zoom(7)
            rptViewer.Show()
        Catch Excep As Exception
        End Try

Thanks lingsn, your code worked!!
