Crystal Report Deployment (VS 2010, VB code)

Question

I am having trouble previewing the report that i created with crystal report. When i tried running the page, it takes a long time to load and nothing seems to appear. I am using the VB codes as listed below. Can someone please help me?
Imports CrystalDecisions.CrystalReports.Engine, CrystalDecisions.Shared, System.Data, System.Data.SqlClient, System.Configuration
Public Class TestingReportView
    Inherits System.Web.UI.Page
    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        Dim rptDoc As ReportDocument = New ReportDocument
        Dim ds As DataSet3 = New DataSet3 ' .xsd file name
        Dim dt As DataTable = New DataTable()
        ' Just set the name of data table
        dt.TableName = "Crystal Report Example"
        dt = getAllOrders() ' This function is located below
        ds.Tables(0).Merge(dt)
        ' Your .rpt file path will be below
        rptDoc.Load(Server.MapPath("CrystalReport1.rpt"))
        ' set dataset to the report viewer.
        rptDoc.SetDataSource(ds)
        CrystalReportViewer1.ReportSource = rptDoc
    End Sub
    Public Function getAllOrders() As DataTable
        ' Connection string replcae 'databaseservername' with your db server name
        Dim sqlCon As String = "User ID=sa;PWD=sa; server=servername;INITIAL CATALOG=SampleDB;PERSIST SECURITY INFO=FALSE;Connect Timeout=0"
        Dim con As New SqlConnection(sqlCon)
        Dim cmd As New SqlCommand()
        Dim ds As New DataSet()
        Try
            con.Open()
            ' Stored procedure calling. It is already in sample db.
            cmd.CommandText = "getAllOrders"
            cmd.CommandType = CommandType.StoredProcedure
            cmd.Connection = con
            Dim Adapter As New SqlDataAdapter(cmd)
            Adapter.Fill(ds, "Users")
        Catch ex As Exception
            Throw ex
        Finally
            cmd.Dispose()
            If (con.State <> ConnectionState.Closed) Then con.Close()
        End Try
        Return ds.Tables(0)
    End Function
End Class

Ok.
1) Make sure you are using the full framework 4.0, not the client framework
2) Make sure you are using CR VS2010 SP 2:
http://downloads.businessobjects.com/akdlm/cr4vs2010/CRforVS_13_0_2.exe
3) Take a look at the following:

4) Download the developer help files:
SAP Crystal Reports .NET API Guide http://help.sap.com/businessobject/product_guides/sapCRVS2010/en/crnet_api_2010_en.zip
SAP Crystal Reports .NET SDK Developer Guide http://help.sap.com/businessobject/product_guides/sapCRVS2010/en/crnet_dg_2010_en.zip
5) Since you are using ADO .NET datasets, see kb [1525432  - Could not load file or assembly 'file:///<Path>crdb_adoplus.dll' or one of its dependencies|http://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/oss_notes_boj/sdn_oss_boj_bi/sap(bD1lbiZjPTAwMQ==)/bc/bsp/spn/scn_bosap/notes%7B6163636573733d36393736354636443646363436353344333933393338323636393736354637333631373036453646373436353733354636453735364436323635373233443330333033303331333533323335333433333332%7D.do]
Finally, a small recommendation; find a saved data report, create a new app (win or web), throw a CR viewer on the form and the following code (on page load or page init);
CrystalReportViewer1.ReportSource = <path to your saved data report>. That should give you your 1st success - work form there.
Oh, and make sure your dataset is not over a couple of thousand rows. Otherwise, you will m ore than likely run into memory issues.
