Error Message :The instruction at "0x7c82f8c7" referenced memory at
"0x00000586". . The memory could not be "read" Platform: Windows 2003 server sp1, Visual Studio 2005 using VB (SP1) I developed a simple appication in vb2005, using crystal reports ReportDocument Object. The program running fine, in debug and release mode, but when you close the program, the above error message appears. I use the debug mode to trace the problem, understand that some memory leakage. So I used the close and dispose methods of Reportdocument object in Form1_Disposed event, but the program indefenitely waiting for something. So I commented the statements in form1_Disposed event The following is the code, Imports CrystalDecisions.CrystalReports.Engine Imports CrystalDecisions.Shared Public Class Form1 Private northwindCustomersReport As ReportDocument Private Sub ConfigureCrystalReports() northwindCustomersReport = New ReportDocument() Dim reportPath As String = Application.StartupPath & "\myReport.rpt" northwindCustomersReport.Load(reportPath) Dim myConnectionInfo As ConnectionInfo = New ConnectionInfo() myConnectionInfo.ServerName = "myserver" myConnectionInfo.DatabaseName = "myDatabase" myConnectionInfo.IntegratedSecurity = True SetDBLogonForReport(myConnectionInfo, northwindCustomersReport) myCrystalReportViewer.ReportSource = northwindCustomersReport End Sub Private Sub SetDBLogonForReport(ByVal myConnectionInfo As ConnectionInfo, ByVal myReportDocument As ReportDocument) Dim myTables As Tables = myReportDocument.Database.Tables For Each myTable As CrystalDecisions.CrystalReports.Engine.Table In myTables Dim myTableLogonInfo As TableLogOnInfo = myTable.LogOnInfo myTableLogonInfo.ConnectionInfo = myConnectionInfo myTable.ApplyLogOnInfo(myTableLogonInfo) Next End Sub Private Sub Form1_Disposed(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Disposed 'If northwindCustomersReport IsNot Nothing Then ' northwindCustomersReport.Close() 'End If GC.Collect() End Sub Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load ConfigureCrystalReports() End Sub End Class |
