Hi - i'm a new user to this forum. I'm using VS2005

I have a report which takes information from an access database. The database has a password. I want the report to work without prompting the user for a password. Looking at various posting i've tried to make the report use a dataset for the datasource

Private Report32 As InspectorErrorReport

Dim Rdataset As ReportDataSet

Dim Rtable As ReportDataSet.InspectorFaultTableDataTable

Dim Radapter As ReportDataSetTableAdapters.InspectorFaultAdapter

Private Sub ReportForm_Load(ByVal sender As Object, ByVal e As system.EventArgs) Handles Me.Load

Rdataset = New ReportDataSet

Radapter = New ReportDataSetTableAdapters.InspectorFaultAdapter

Rtable = New ReportDataSet.InspectorFaultTableDataTable

Rtable.Clear()

Radapter.Fill(Rtable)

Report32 = New InspectorErrorReport

Report32.SetDataSource(Rtable)

CrystalReportViewer1.ReportSource = Report32

CrystalReportViewer1.DisplayGroupTree = False

End Sub

The error that i keep getting is

Overload resolution failed because no accessible 'SetDataSource' is most specific for these arguments: 'Public Overridable Sub SetDataSource(dataTable As System.Data.DataTable)': Not most specific. 'Public Overridable Sub SetDataSource(enumerable As System.Collections.IEnumerable)': Not most specific.

Please can anyone help. Thanks in advance

Instead of creating a new DataTable, have you tried just setting it like this:

Report32.SetDataSource(ReportDataSet.InspectorFaultTableDataTable)

I work in C#, not in VB, but here's what I've done in the past in a Windows app:

In the code for the viewer form, I modify the constructor to take a DataSet as a parameter. The main code for the viewer form looks like this:


public ViewerForm(DataSet ds)

{
  InitializeComponent();
  ConfigureCrystalReports(ds);
}
private void ConfigureCrystalReports(DataSet ds)

{
  rpt = new BOEUserAuditRpt();
  rpt.SetDataSource(ds);
  rptViewer.ReportSource = auditRpt;
}[\code]
 
The code that calls this looks like this:[code]

private void RunReport()

{
  ViewerForm viewer = new BOEAuditRptViewer(dsAuditInfo);
  viewer.Show(); 
}
