Maybe you can find more information here: Crystal Report Login Prompt[^]

It seems the good people at CodeProject are a bit tired of all those Crystal Report problems.
So if no one answers your question take a look at an alternative like FastReport,
see: open-source-reporting-tools[^]

Provide login info for each datatable in crystal report

VB
With TblInfo.ConnectionInfo
            .ServerName = Utils.getConStr("Datasource")
            .DatabaseName = Utils.getConStr("DataBase")
            .UserID = Utils.getConStr("user")
            .Password = Utils.getConStr("pwd")
        End With

        With pReport
            .Database.Tables(0).SetDataSource(pDS.Tables(0))
            .Database.Tables(0).ApplyLogOnInfo(TblInfo)
            .RecordSelectionFormula = ""
            For i As Integer = 0 To pReport.Subreports.Count - 1
                If .Subreports(i).Database.Tables.Count > 0 Then
                    .Subreports(i).Database.Tables(0).ApplyLogOnInfo(TblInfo)
                    .Subreports(i).Database.Tables(0).SetDataSource(pDS.Tables(.Subreports(i).Database.Tables(0).Name))
                    '.Subreports(i).RecordSelectionFormula = ""
                End If
            Next
        End With
