    Runtime Error '20534' : Error detected by database dll

    I have facing problem with vb6 and crystal report 8 . The error message is "Runtime error '20534' : Error detected by database dll". If i remove the red color line. It don't have any error.

    Private Sub VIButton15_Onclick()
    If docheck = True Then

    Call clearReport

    If optSearch(0).Value = True Then
    Report.SelectionFormula = "{Sales.Receiptno} >='" & txtfrom & "' and {Sales.Receiptno} <='" & txtTo & "'" & temp
    End If
    If optSearch(1).Value = True Then
    Report.SelectionFormula = "{Sales.Salesdate} >=" & changerptdate(txtfrom) & " and {Sales.Salesdate} <=" & changerptdate(txtTo) & temp
    End If



    Report.ReportFileName = Reportpath & "\CustomSales\10Topsalesbyitems.rpt"

    Report.Formulas(0) = "company ='" & Branchid.Text & "'"
    Report.Formulas(1) = "DateRange ='Sales Date from " & txtfrom & " to " & txtTo & "'"

    Report.Action = 1

    End If
    End Sub

    Probably
    This error will occur due to wrong formula or the selection formula so check them first in debug mode.
    As I got error in the red line you are using the date with the wrong selection formula.
    So just read how to use the date in the selection formula. I suggest you that just read the crystal report tutorial at my signature, where I provide example for using date in the selection formula.
