Crystal also Hangs.

If I try to use fields from more than one table in dataset the report hangs.

I have three tables Customer, Orders, orderdetails. I create a dataset in my project with the three tables with relations:
Customers----> Orders ----> Orderdetails.

I create a report with the wizard that contains the three tables linked in the same manner as the relations. grouped by Orders.OrderId and ordered by this field.

I have a form that executes that has the crystalviewer and the follwing code in the load event.

Code:

---

        Dim connstring As String = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + _
                                    "C:\ReynerioData\Nwind\nwind.mdb"

        Dim conn As OleDbConnection = New OleDbConnection(connstring)

        Dim oledbadap As OleDbDataAdapter = New OleDbDataAdapter("Select * from Customers", conn)
        Dim oledbAdapOrdr As OleDbDataAdapter = New OleDbDataAdapter("SELECT * FROM Orders", conn)
        Dim oledbAdapOrdrDetails As OleDbDataAdapter = New OleDbDataAdapter("Select * from [Order Details]", conn)
        'Dim oledbAdapCustCat As OleDbDataAdapter = New OleDbDataAdapter("Select * from CustCat", conn)

        Dim NwindDataset1 As New nwindDataSet

        oledbadap.Fill(NwindDataSet1.Customers)
        oledbAdapOrdr.Fill(NwindDataset1.Orders)
        oledbAdapOrdrDetails.Fill(NwindDataset1.Order_Details)

        Dim rpt As New CrystalReport3

        rpt.SetDataSource(NwindDataset1)

        Me.CrystalReportViewer1.ReportSource = rpt

When I execute the code if I have fields from more than one of the tables the form hangs.

It works fine if I use ado but not if I use ado.net.

It is using OLEdb (Access).

Any suggestions?

PS Do you all use the crystal for reporting in VB or do you think there is something better out there?

If you use ado.net then its different as you need to deploy the merge modules depending on your CR version. Are you setting the logon info for all tables?

I'm getting thi8s problem in development mode. The application has not been deployed.

I dont see in your code where you are using the .SetlogonInfo credientials.

I don't need to set logon info. The database and ado.net manage the connections to the database.

Besides if I use fields from only one table it will work ok. but if I use more than one table thats were it will hang.:mad:
