UI Loading Cystal Reports 2008 ActiveX Viewer into SAP B1

Question

I have been looking over Code Samples, Help Forums and documentation from Business Objects for pas 5 hours. I made this work with VS2003 and CR10 but now im running VS2005 with CR2008.
Here is my code; It crashes on the bold line with the message: "Invalid cast".
The report is there and valid.
It does not even connect to a database; it has one text field in the header containing "Helloworld"
Oh and one more thing; i dont have this class CRAXDDRT. Im assuming that the class was stopped at CR11...
Imports CrystalDecisions.CrystalReports.Engine
Imports CrystalDecisions.Shared
Public Class cCRViewer
    Protected oForm As SAPbouiCOM.Form
    Protected oDataSources As SAPbouiCOM.UserDataSources
    Protected WithEvents oCRViewer As CrystalActiveXReportViewerLib12.CrystalActiveXReportViewer
    Public ocr As New ReportDocument
    Public Sub New()
        Dim oActiveX As SAPbouiCOM.ActiveX
        Dim oItem As SAPbouiCOM.Item
        Try
            oForm = oApplication.Forms.Add("NewClass", SAPbouiCOM.BoFormTypes.ft_Sizable, "900201")
            oDataSources = oForm.DataSources.UserDataSources
            oItem = oForm.Items.Add("Viewer", SAPbouiCOM.BoFormItemTypes.it_ACTIVE_X)
            oActiveX = oItem.Specific
            oActiveX.ClassID = "CrystalReports12.ActiveXReportViewer.1"
            oCRViewer = oActiveX.Object
            ocr.Load("D:\TEST.rpt")
            oCRViewer.ReportSource = ocr
            oForm.Visible = True
        Catch ex As Exception
        End Try
    End Sub
Thanks

Answer 1

Denis,
I don't know what's wrong will your code, but I can tell I'm using a .NET form to show the ReportViewer.
