Hi everyone,

I have a Crystal Report with a subreport in a windows application,
which is to be exported to the pdf file. I followed the instructions
on http://support.crystaldecisions.com/library/kbase/articles/c2010275.asp
to set up the log on information. But I always got the exception at
the statement:
tbl.Location = ...;

The error message is listed below:

An unhandled exception of type
'CrystalDecisions.CrystalReports.Engine.InvalidArgumentException'
occurred in crystaldecisions.crystalreports.engine.dll

Additional information: Error in File C:\tmp2\rptMain.rpt:
Invalid table number.

Can anyone help me on this problem? Thank you so much in advance.

p.s. the datasets in the reports were created against views. But I
don't think this could cause any problem.
 
Here is my code:
/**************************************************************/

Table crTable;
TableLogOnInfo crLogOnInfo = new TableLogOnInfo();
ConnectionInfo crConnInfo = new ConnectionInfo();
foreach(Table tbl in ReportDoc.Database.Tables)
{
crConnInfo.ServerName = "cia_sql2000";
crConnInfo.DatabaseName = "cia";
crConnInfo.UserID = "sa";
crConnInfo.Password = "#ciasql";
crLogOnInfo = tbl.LogOnInfo;
crLogOnInfo.ConnectionInfo = crConnInfo;
tbl.ApplyLogOnInfo(crLogOnInfo);
tbl.Location = tbl.Location.Substring(tbl.Location.LastIndexOf(".")+1);
}
/***********************************************************************/

It always failed at the last statement no matter whether I explicitly
provided the location.
 
Hi Anannj,

I think the last two lines in your code should be reversed. Following is the
Vb.Net code I use for CR report init in my apps.
Private Sub ReportInit(ByVal blRefreshLocation As Boolean)

Dim crSections As Sections
Dim crSection As Section
Dim crReportObjects As ReportObjects
Dim crReportObject As ReportObject
Dim crSubreportObject As SubreportObject

Dim crReportDocument As ReportDocument
Dim crSubreportDocument As ReportDocument

Dim crDatabase As Database
Dim crTables As Tables
Dim crTable As Table
Dim crTableLogOnInfo As TableLogOnInfo
Dim crConnectioninfo As ConnectionInfo

Dim myArrayList As ArrayList = New ArrayList

'declare an instance of the report and the connectionInfo object

crReportDocument = New ReportDocument
crConnectioninfo = New ConnectionInfo

crReportDocument.Load(mstrReportName)

'pass the necessary parameters to the connectionInfo object
With crConnectioninfo
.ServerName = mstrDBServerName
.DatabaseName = mstrDataBaseName
End With

'set up the database and tables objects to refer to the current report
crDatabase = crReportDocument.Database
crTables = crDatabase.Tables

'loop through all the tables and pass in the connection info
For Each crTable In crTables
crTableLogOnInfo = crTable.LogOnInfo
crTableLogOnInfo.ConnectionInfo = crConnectioninfo
If blRefreshLocation Then
crTable.Location = mstrDataBaseName & ".dbo." &
crTable.Location.Substring(crTable.Location.LastIndexOf(".") + 1)
End If
crTable.ApplyLogOnInfo(crTableLogOnInfo)
Next

'set the crSections object to the current report's sections
crSections = crReportDocument.ReportDefinition.Sections

'loop through all the sections to find all the report objects
For Each crSection In crSections
crReportObjects = crSection.ReportObjects
'loop through all the report objects to find all the subreports
For Each crReportObject In crReportObjects
If crReportObject.Kind = ReportObjectKind.SubreportObject Then
'you will need to typecast the reportobject to a
subreport
'object once you find it
crSubreportObject = CType(crReportObject, SubreportObject)

'open the subreport object
crSubreportDocument =
crSubreportObject.OpenSubreport(crSubreportObject.SubreportName)

'set the database and tables objects to work with the
subreport
crDatabase = crSubreportDocument.Database
crTables = crDatabase.Tables

'loop through all the tables in the subreport and
'set up the connection info and apply it to the tables
For Each crTable In crTables
With crConnectioninfo
.ServerName = mstrDBServerName
End With
crTableLogOnInfo = crTable.LogOnInfo
crTableLogOnInfo.ConnectionInfo = crConnectioninfo
If blRefreshLocation Then
crTable.Location = mstrDataBaseName & ".dbo." &
crTable.Location.Substring(crTable.Location.LastIndexOf(".") + 1)
End If
crTable.ApplyLogOnInfo(crTableLogOnInfo)
Next
End If
Next
Next

crystalReportViewer.ReportSource = crReportDocument

End Sub

Cheers, Peter
 
Thanks, Peter.

I swaped the last two statements but the error is still there. It
worked fine if there was no subreport...

Anannj
