I am calling a report designed in Crystal Report in a VB Project.
I want to replace the current selection formula by another simple formula
(the same field is being in use)
But it gives the following error
example source

Private Sub Command1_Click()
Dim strSQL As String
strSQL = "{TableName.SerialNo} > " & Val(Text1.Text)
CrystalReport1.ReplaceSelectionFormula strSQL
CrystalReport1.Action = 1
End Sub


Run Time error '20536'
Unable to connect:incorrect log on parameters


HOW TO GO AHEAD?
