Dim crParameterValues As New ParameterValues
Dim crParameterDiscreteValue As New
ParameterDiscreteValue
crParameterDiscreteValue.Value = TextBox2.Text
crParameterFieldDefinitions = _
cryRpt.DataDefinition.ParameterFields
crParameterFieldDefinition = _
crParameterFieldDefinitions.Item("cpvid")
crParameterValues =
crParameterFieldDefinition.CurrentValues
crParameterValues.Clear()
crParameterValues.Add(crParameterDiscreteValue)
crParameterFieldDefinition.ApplyCurrentValues(crParameterValues)
Form5.CrystalReportViewer1.ReportSource = cryRpt

I would like to pass a parameter to my report and put the report into my project.
I want to pass a user id as parameter to the report.
The id will be different each time.
Can someone help me on this topic how to pass the parameter.
Here is my code so far:
CrystalReportViewer1.Visible = True
Dim rDoc As New ReportDocument()
' Crystal Report Name
rDoc.Load(Server.MapPath("Sucess.rpt"))
' Your .rpt file path
'set dataset to the report viewer.
CrystalReportViewer1.ReportSource = rDoc
You can try something like this:
string ponumber;
string receiptno;
ponumber = TextBox1.Text;
CrystalReportSource CrystalReportSource1 = new CrystalReportSource();
CrystalReportViewer CrystalReportViewer1 = new CrystalReportViewer();
CrystalReportViewer1.ReportSource = CrystalReportSource1;
CrystalReportViewer1.EnableParameterPrompt = false;
CrystalReportSource1.Report.FileName = "Report3.rpt";
CrystalReportSource1.EnableCaching = false;
CrystalReportSource1.ReportDocument.SetParameterValue(0, ponumber);
CrystalReportSource1.ReportDocument.SetParameterValue(1, receiptno);

I am working with VS 2005 and using visual basic for coding.
How do I set up the connection object for my crystal report using vb code.
I have written some code
Dim strcon As String = ConfigurationManager.AppSettings("PhdConnectionString")
Dim getconn As SqlConnection = New SqlConnection(strcon)
Dim rpt As ReportDocument = New ReportDocument
rpt.Load(Server.MapPath("aspirantCrystalReport.rpt"))
// I want to set the connection properties here. How do I do that ?
CrystalReportViewer1.ReportSource = rpt
CrystalReportViewer1.DataBind()
I have not done this using the Crystal Reports .NET API, but I do have a working piece of code written in VB6 that calls the COM API. The API class and member names can't be that different.
