Using Crystal Reports in Visual Basic 2010

Question

I am trying to add several Crystal Reports to a new project and having a major problem.  Here's the situation. I created a new Visual Basic 2010 project with only one form, In visual Basic I added Crystal Reports.   I then imported a form that was created in Crystal Reports 8.5.
There were no errors and the report with valid data was visible. I then tried to run...it wouldn't run and 31 errors appeared.
Obviously I missed something. I have searched for a very simple basic tutorial and  either can't find one or didn't recognize one.
Can anyone point me in the right direction.

Ok. So, you added the report to the project. Now we have to add the CR assemblies to the project, add the viewer (if need be) and fire it off. Simplest code would be:
Public Sub New()
        ' This call is required by the designer.
        InitializeComponent()
        ' Add any initialization after the InitializeComponent() call.
        CrystalReportViewer1.ReportSource = ("path to report")
    End Sub
In this case you are using the viewer SDK to runt he report. The report will prompt for any logon parameters - but you can code these also. You can load the report via the engine as bellow. Again, the report will prompt. I prefer to use the engine as it is way more "extensible"...
Public Sub New()
        ' This call is required by the designer.
        InitializeComponent()
        ' Add any initialization after the InitializeComponent() call.
        Dim crReportDocument As New CrystalDecisions.CrystalReports.Engine.ReportDocument()
        crReportDocument.Load("path to report")
        'Bind the report to the viewer
        CrystalReportViewer1.ReportSource = crReportDocument
    End Sub
If you have a report added to the project (strongly typed) the code would be:
CrystalReportViewer1.ReportSource = New myReport()
For more details, I'd recommend looking at the sample app vbnet_win_simplepreviewreport.zip available from the following location:
