[RESOLVED] CRXI and SQL Server Connection Problems
Hi,
I've built and rolled out an app that contains a Crystal Reports Viewer for reporting purposes which connects to a Db on a SQL Server. The code I'm using to connect is below.
The problem I'm having is everytime the user opens a new or different report they are opening a new process on the server which is causing performance issues.
Can anyone tell me how I can close the connection each time the load report has been completed.
Thanks
VB Code:
Try
'Loop through each table in the report and set the connection info
crTables = crReportDocument.Database.Tables
For Each crTable In crTables
crtableLogoninfo = crTable.LogOnInfo
crtableLogoninfo.ConnectionInfo = crConnectioninfo
crTable.ApplyLogOnInfo(crtableLogoninfo)
Next
Catch ex As Exception
MsgBox("Unable to Log On To report Tables", MsgBoxStyle.Critical)
MsgBox("Loading of " & strReportName & " Cancelled.", MsgBoxStyle.Information)
'MsgBox(ex.ToString)
GoTo StopHere
End Try
Try
' Loop through each section and find report objects
crSections = crReportDocument.ReportDefinition.Sections
For Each crSection In crSections
crReportobjects = crSection.ReportObjects
For Each crReportobject In crReportobjects
If crReportobject.Kind = ReportObjectKind.SubreportObject Then
' If a subreport is found cast as subreportobject
crSubReportobject = CType(crReportobject, SubreportObject)
' Open the sub report
subReportDocument = crSubReportobject.OpenSubreport(crSubReportobject.SubreportName)
crDatabase = subReportDocument.Database
crTables = crDatabase.Tables
' Loop through each table in the sub report and set the connection info
For Each crTable In crTables
crtableLogoninfo = crTable.LogOnInfo
crtableLogoninfo.ConnectionInfo = crConnectioninfo
crTable.ApplyLogOnInfo(crtableLogoninfo)
Next
End If
Next
Next
Catch ex As Exception
MsgBox("Unable to Log On To Sub Report Tables")
' MsgBox(ex.ToString)
End Try
