Hi Raymond,

If you are trying to use variables from your VB .NET code then you need to use the ParameterValues array and the ParameterDiscreteValue class. You create a Paramater Field in Crystal Reports and then in the Record Selection you use the Parameter Field. Here is the VB .NET code to populate the parameter value and then call the report. This sample is using the Northwind Customer table and passing in the CustomerID I want to display. I created a Paramter Field called "MyParam":

Dim oReport As New CrystalReport1()

Dim paramValues As New ParameterValues()
Dim discreteValue As New ParameterDiscreteValue()

' Set your parameter variable here
discreteValue.Value = "ANTON"
paramValues.Add(discreteValue)

oReport.DataDefinition.ParameterFields("MyParam").ApplyCurrentValues.(paramValues)
crystalReportViewer1.ReportSource = oReport

For the Crystal Reports Record Selection, here is what I am using for syntax:

{Customers.CustomerID} = {?MyParam}
