crystal report not refreshing data

hello,

I am using CR8 with vb6. I have created a report using icr designer. The report connects to the database using a system dsn. The report uses the tables emp_mast and pay_det. For testing I put the the fields emp_name and emp_designation from emp_mast in the report and viewed the report. It worked perfectly well.

Now my special requirement is that I will be using separate databases with the same datastructure for reporting at different occasions as I will be receiving different databases from field offices. In other words, I will be selecting the datasource for the reports every time I open the application. To try this, I tried the following code,

VB Code:

Dim Dim strSql As String
Dim rst As ADODB.Recordset
Dim cnn As ADODB.Connection
cnnString As String
Dim Report As New rptAdmitCard
 
    cnnString = "Provider=MSDASQL; DRIVER={Microsoft Access Driver (*.mdb)}; DBQ=c:\mydir\mydb.mdb; UID=; PWD=;"
 
    Set cnn = New ADODB.Connection
    cnn.Open cnnString
    strSql = "select * from emp_mast"
    Set rst = New ADODB.Recordset
    rst.Open strSql, cnn, adOpenStatic, adLockReadOnly, adCmdText
 
    Report.Database.SetDataSource rst
    Screen.MousePointer = vbHourglass
    CRViewer1.ReportSource = Report
 
    CRViewer1.ViewReport
    Screen.MousePointer = vbDefault
    rst.Close
    cnn.Close
    Set rst = Nothing
    Set cnn = Nothing

But the report is still displaying from the old database only, not from mydb.mdb

Will someone pls tell me where I have gone wrong ???
thanx
