if you have Crystal Developer installed on the machine running the Access database, viewing reports with the ActiveX viewer is rather simple...
If you are planning on coding in VB: go here:
If you just want to use the ActiveX objects in an Access form,
1. Place the Crystal Report Control on a form and set the "ReportFileName" property = to your C:\...file path\report.rpt (it will allow you to browse for it.)
Here you can set any additional properties you may need.
2. Place a Command Button on the form, cancel the wizard, and put the this in the On Click() event(no brackets):
Private Sub [commandbuttonname]_Click()
[CRReportControlName].PrintReport
End Sub
This should get you started...but please keep in mind, distributing these reports to users only running Access is a whole different can of worms...
If you're looking to allow others to view reports, it's easiest to create them in Access...
