for the recordset to be passed to Crystal at runtime u have to follow the following steps

1. When designing the report you have to select custom reports sqlodbc.
2. This will pop up another screen where you have to select Active Data (Field Definitions Only).
3. This will pop another screen called Select data source (data Definition) click on the new option Button
4. This will bring another screen where you have to enter the fields and their data types which are to be shown on the report.Save the file (extension .ttx)
and use that to design your report.
    The report will be a dumb report because you are not connected to any data source at this moment.

The requirement is that you have to use vb6.0 with Crystal 7.0 or you can download the report designer component from the seagate web site for free.

In Vb under the project menu you will have add crystal report click that.

This will bring the designer up say import report and bring the report which you have created above.

Then another screen will pop up which will ask if you need the viewer and if you want it to be the starting form.
Say yes to the viewer wanting option and say no to make the viewer the startup object.

For more than one report you can say no to both the options as you can use the same viewer for all the reports.

The declaration will have something like this

Dim Report As New CrystalReport1
(The report which you have imported
You can give the name you want to give)

Dim cnn1 As New ADODB.Connection
Dim rstTest As ADODB.Recordset
Dim rstUser As ADODB.Recordset
Dim strCnn As String
Dim varDate As Variant
Dim sql As String

Now connect to the database
Private Sub Form_Load()
   ' Open connection.
   strCnn = "Data Source=blackhawk;User=dba;Password=chelios; " 
   Set cnn1 = New ADODB.Connection
   cnn1.Open strCnn

Fire the sql query
     
sql = "select us.user_guid,us.user_last_name, us.user_first_name,us.user_middle_name,ir.lilevel,ir.listatus," & _
    " ir.palevel,ir.pastatus,ir.swlevel,ir.swstatus,ir.wclevel,ir.wcstatus,ir.scon,ir.pclevel,ir.pcstatus" & _
      " from blackhawk01.dba.users us,blackhawk01.dba.ir_history ir where us.user_guid = ir.student_guid " 

( Open the recordset and dump the recorset with the result of the query)

   Set rstUser = New ADODB.Recordset
   rstUser.CursorType = adOpenKeyset
   rstUser.LockType = adLockOptimistic
   rstUser.Open sql, cnn1, dOpenKeyset, adLockOptimistic

Screen.MousePointer = vbHourglass
(the report source is the report which is created)

CRViewer1.ReportSource = Report
(Set the datasource of the report with the recordset you have created)

Report.Database.SetDataSource rstUser
CRViewer1.ViewReport
Screen.MousePointer = vbDefault
