When you need to pass properties to a report, you can do so using Visual Basic's Property structure:

  
Dim m_someProperty As String
 Public Property Let SomeProperty(myString As String)
 Let m_someProperty = myString
 End Property 

The property can then be accessed by the calling code:

  
Private Sub Form_Load()
 Dim rpt As New rptPublicProperty
 rpt.SomeProperty = "This is the value that has been passed in from frmStartup"
 rpt.Run
 Me.ARViewer21.ReportSource = rpt
 End Sub 

This allows you to pass strings and other values in for use inside your report.

Note: You must have build 1253 or later in order to run the attached sample.
