Native connection in Crystal Report 9 Viewer

Hi All,
I am using Crystal Report 9 and VB6.

I want to display the reports using the native connection to my MS SQL 2005 dbase

And I use the following code to view the crystal report

VB Code Code:

Dim CrystApp As CRAXDRT.Application
Dim CrystRpt As CRAXDRT.Report
 
Set CrystApp = New CRAXDRT.Application
Set CrystRpt = CrystApp.OpenReport(App.Path & "\PymntRpt.rpt")
CrystRpt.Database.Tables(1).SetLogOnInfo "MyServer", "MyDb", "MyUsr", "MyPwd"

I get the following Error :
Details: IM002:[Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified

But when I use the same code to connect using ODBC connection it work properly

VB Code Code:

Dim CrystApp As CRAXDRT.Application
Dim CrystRpt As CRAXDRT.Report
 
Set CrystApp = New CRAXDRT.Application
Set CrystRpt = CrystApp.OpenReport(App.Path & "\PymntRpt.rpt")
CrystRpt.Database.Tables(1).SetLogOnInfo "MyODBC", "MyDb", "MyUsr", "MyPwd"

This code work with ODBC connection.

In my case, I need to connection using Native connection method

How can I solve this problem and connect to my SQL Sever using native connection method in Crystal Report 9.

With regards,
Nasreen

Crystal Reports 9
To use the native driver, try :

Code:

---

CrystRpt.Database.Tables(1).SetLogOnInfo "MyServer", "MyServer", "MyUsr", "MyPwd"

---

Also:
The 'SetLogonInfo' is a deprecated method in Crystal Reports 9
You have to use the 'ConnectionProperty' instead

Hi jggtz
Thanks for your replay.

Your code :
CrystRpt.Database.Tables(1).SetLogOnInfo "MyServer", "MyServer", "MyUsr", "MyPwd"
is the same that I am trying with, but there is not database name in your code. However I get error by this code also

Regarding to the use of 'ConnectionProperty' :
I have no much idea about it. Can u pls give me an example how to use this 'ConnectionProperty' modifying my codes.

With regards,
Nasreen

The next is an example to send data path to a Crystal Reports' report using VB6.
In this example, the report is designed using ADO OLE DB (MS Access) as data source, then you have to modify to your data source requirements;
(in order to know these requirements , enter to Crystal Reports, select: menu / Database / SetDatasourceLocation / Current Data Source / Properties to display the properties you have to provide thru vb code )

Code:

        Set CRConProp = CRTabla.ConnectionProperties("Database Type")
            CRConProp.Value = "OLE DB (ADO)"
        Set CRConProp = CRTabla.ConnectionProperties("Provider")

        Set CRConProp = CRTabla.ConnectionProperties("Data Source")

            CRConProp.Value = "Admin"

            CRConProp.Value = "Access"
        Set CRConProp = CRTabla.ConnectionProperties("Locale Identifier")
            CRConProp.Value = "1033"

    Next MInt2

        Select Case CRReport.FormulaFields(MInt2).Name

                CRReport.FormulaFields(MInt2).Text = "Trim(" & Chr(39) & GTitleA & Chr(39) & ")"
            Case "{@b}"

        CRReport.RecordSelectionFormula = GSelFor
    End If
   
    'frmReport is the form that contains the CR9Viewer
    frmReport.Show vbModal 
   
    'Release resources
    Set CRTabla = Nothing
    Set CRConProp = Nothing
    Set CRReport = Nothing
    Set CRAplicacion = Nothing

And this is the code in frmReport :

Code:

---

Private Sub Form_Load()
   
    Me.Caption = GTitleA
   
    CRViewer1.ReportSource = CRReport
    CRViewer1.Zoom 1
    CRViewer1.ViewReport
   
End Sub
