make sure your tables are named the same as the typed dataset you generated (also that all fields are there) if it is missing a field/table it will prompt for a database connection.

I've seen this dialog before... sometimes it pops up if the crystal reports shared assemblies are of the wrong version. Is it possible that you have two versions of the Crystal Shared assemblies on the same computer?

HINT: Check the GAC.

The CR gets the values from 2 datasets and 3 tables


DataSet1
------------
---MyTable
------ID
------Name

Dataset2
-------------
---MyTable
------Description
------ID


no in CR i linked the ID of dataset2 mytable to the dataset 1 mytable .

Well in that case, have you tried supplying the login credentials to the database through CR?

Heres a sample of a CR report connection to a Database

 
Imports CrystalDecisions.CrystalReports.Engine
Imports CrystalDecisions.ReportSource
Imports CrystalDecisions.Shared

    Public myReport As New ReportDocument        'Gobal Report Doc
 
  '**** Server Connection Vars *********
    Public sDBServer As String = "MYSERVER"
    Public sUSERid As String = "MYUSER"
    Public sDBName As String = "MYDATABASE"
    Public sDBPass As String = ""

 Private Sub GetReportConnection(ByVal myReport)
        ' Objects used to set the proper database connection information
        Dim tbCurrent As CrystalDecisions.CrystalReports.Engine.Table
        Dim tliCurrent As CrystalDecisions.Shared.TableLogOnInfo
        Dim sMYPATH as string      '<-----Directory for your reports
        Try
            ' Load the report
            myReport.Load(sMYPATH, CrystalDecisions.[Shared].OpenReportMethod.OpenReportByTempCopy)
            ' Set the connection information for all the tables used in the report
            For Each tbCurrent In myReport.Database.Tables
                tliCurrent = tbCurrent.LogOnInfo
                With tliCurrent.ConnectionInfo
                    .ServerName = sDBServer
                    .UserID = sUSERid
                    .Password = ""
                    .DatabaseName = sDBName
                End With
                tbCurrent.ApplyLogOnInfo(tliCurrent)
            Next tbCurrent
        Catch Exp As LoadSaveReportException
            MsgBox("Incorrect path for loading report.", _
                    MsgBoxStyle.Critical, "Load Report Error")
        Catch Exp As Exception
            MsgBox(Exp.Message & "   in GetReportConnection Procedure", MsgBoxStyle.Critical, "General Error")
        End Try
    End Sub

he is using push mode greg. you don't need to give credentials ... most likely it is a misnamed table or a missing field / relationship.

push model. yeah, the only thing I can think of involves referencing the wrong version of the shared assemblies.

But if its not that, i'm not sure. but interested in knowing the end resolution.

crystal is not known for being easy to work with.

as i said make sure your tables have the same names .. that is the major cause I get here using push model ...

DataAdapter.Fill(ds, "CorrectTableName");

in this case the first one brings up a good point but off ... you need to set the datasource for your subreports (not the login)

First go to your report, and VERIFY the database.  This will let you know if you made any changes in your dataset(s) after creating your report.
I generally get the Logon message when I had an error filling my Dataset(s).
Normally one of the Datasets is NOTHING.

Put a break point just before you set your datasource in Crystal; IE.
      myREPORT.SetDataSource(myDATASET)

Then make sure you can see the data within your myDS in all tables.

Hope this helps you out.
