My WinForm solution calls my reports via menu options. As a result each menu item has _click event handlers. Here's an example:

Private Sub mnuReportAlpha_click(........) Handles.....
Dim frmCurrent as FrmReportNHGAlpha
frmCurrent = New FrmReportNHGAlpha
FrmCurrent.ShowDialog()
end sub

The CrystalReportViewer1 properties for the frmReportNHGAlpha are basic. This report has a formula "Add2" --> Formula = trim({NHGList.City}) + ", " + {NHGList.State} embedded into the Cyrstal report's formula editor.
