Re: How do i do a notnull statement? (If (IsNotNull(..) Then ...)

by "Douglas J. Steele" <NOSPAM_djsteele@[EMAIL PROTECTED] > Dec 3, 2008 at 09:05 AM

To check for either Null or zero-length string (""), use

    If Len(txtSuppliedProductID & vbNullString) > 0 Then
            WHERE = " AND productID=" & txtSuppliedProductID.Text
        Else
            If Len(cmoSuppliedProductName & vbNullString) > 0 Then
                WHERE = " AND productID=" & cmoSuppliedProductName.Text
            End If
    End If
