I have a c# application that used IIS 10, that has been working for many years with using the session id to track the users selections across the site.
I did an update this week and I messed something up and I can't seem to pinpoint where the change was made.
I added a textbox on the same page on both test and production.
<asp:TextBox runat="server" ID="txtSession" ></asp:TextBox>
protected void Page_Load(object sender, EventArgs e)
{
txtSession.Text = Session.SessionID.ToString();
}
On test when I refresh the session id stays the same, but when I'm on production the session id changes when I refresh or go to a different page. I'm reviewed my web.config on both sides and can't see where this is an issue. This is the only session row in web.config on both side
<sessionState mode="InProc" timeout="120"/>
Within the global.asax.ca has the following
protected void Session_Start(object sender, EventArgs e)
{
Session.Timeout = 60;
Session["User"] = "";
Session["UserLevel"] = 0;
Session["EmptyFields"] = -1;
//Session["SelectedID"] = "";
}
So it is Any help would be greatly appreciated. I've been going over this for almost 2 days and I can't seem to find the issue. Part of my updated including updating to oracle managed data access dlls. This also exists on test and it working fine.
I figured out the issue was the following files were deleted from the bin directory.
App_global.asax.compiled
App_global.asax.dll
As soon as I copied them back everything started working.
I have a Moto Mc9096 device, EDMK SDK, VS2008 etc all of the prereq's
I'm having an issue where once I've scanned a barcode it constantly repeats the event. normally when this happens its a flag or status needs changing but there are no obvious settings to stop it reading again.
code below
private void Barcode_Read(object sender, ReaderData readerdata)
{
if (readerdata.Text != null)
{
if (readerdata.Text == "abc")
{
MessageBox.Show(readerdata.text);
}
}
}
Notes
I've tried
bar.Dispose();
bar.Reader.Actions.Flush();
bar.ReaderData.Dispose() ;
with no success. the EnabledScanner is set on form load and off during form close.
My expectation was when the user scans a barcode it fires the read event once.
but it constantly fires after the users first scan.
You might want to check the aimType property, by default it should be AIM_TYPE_TRIGGER but other settings allow a single trigger pull to perform multiple scans (AIM_TYPE_CONTINUOUS_READ) so perhaps that has been changed.
You should have some samples installed by the SDK at file:///C:/Users/Public/Motorola%20EMDK%20for%20.NET/v2.9/SampLauncher2008.htm (by default) that show best practice.
I'm facing a very buggy issue, in ASP.NET application after viewing the same report many times simultaneously I got this exception:
The maximum report processing jobs limit configured by your system
administrator has been reached.
Wait I know there are tons of solutions out there but all of them are not working with me.
I put ReportDocument.Close(); ReportDocument.Dispose(); in CrystalReportViewer_Unload event, and still throw the exception.
Private Sub CrystalReportViewer1_Unload(ByVal sender As Object, ByVal e As System.EventArgs) Handles CrystalReportViewer1.Unload
reportFile.Close()
reportFile.Dispose()
GC.Collect()
End Sub
I edit the PrintJobLimit registry in HKEY_LOCAL_MACHINE\SOFTWARE\SAP BusinessObjects\Crystal Reports for .NET Framework 4.0\Report Application Server\InprocServer and HKEY_LOCAL_MACHINE\SOFTWARE\SAP BusinessObjects\Crystal Reports for .NET Framework 4.0\Report Application Server\Server to -1 even to 9999, and still throw the exception.
Here is the code snippet where I call my report:
Table_Infos = New TableLogOnInfos()
Table_Info = New TableLogOnInfo()
Con_Info = New ConnectionInfo()
With Con_Info
.ServerName = ConfigurationManager.AppSettings("server_name")
.DatabaseName = ConfigurationManager.AppSettings("DB")
.UserID = user_name
.Password = pass_word
.Type = ConnectionInfoType.SQL
.IntegratedSecurity = False
End With
Table_Info.ConnectionInfo = Con_Info
If Session("recpt_lang") = "Arabic" Then
reportFile.Load(Server.MapPath("/Reports/") & "collectrecpt_new_ar.rpt")
ElseIf Session("recpt_lang") = "English" Then
reportFile.Load(Server.MapPath("/Reports/") & "collectrecpt_new.rpt")
End If
For Each mytable In reportFile.Database.Tables
mytable.ApplyLogOnInfo(Table_Info)
Next
CrystalReportViewer1.ReportSource = reportFile
CrystalReportViewer1.SelectionFormula = Session("SelectionForumla")
CrystalReportViewer1 = Nothing
You have to Dispose your report instance after all.
If you Dispose the report after showing it, you will never see the error "The maximum report processing jobs limit configured by your system administrator has been reached" again.
Dim report1 As rptBill = clsBill.GetReport(billNumber)
rpt.Print()
'Cleanup the report after that!
rpt.Close()
rpt.Dispose()
I would recommend moving your close/dispose/gc.collect code outside of that unload process. In other words:
Load report
Assign to Viewer Control
Show Report in Viewer Control
Close Viewer Control and Unload (completely)
Then close/dispose/gc.collect outside of any viewer control code
My guess is the viewer control is not completely closed when the report is being cleaned up.
Crystal is a very memory intensive process and very finicky.
Crystal Report document implements IDisposable interface. So all you have to do is to enclose the report's instance with using statement. It will be automatically closed and disposed once the using statement is completed. You can write something like that:
using(var report = GetInvoiceReport())
{
// your logic here
}
or (depends on your context):
using(var report = new ReportDocument())
{
// your logic here
}
Greetings I am too late to have answer on it,
all reply are working and i have seen but in case still you are facing same problem and error then please once go in to TEMP folder under "windows" directory and delete all instances of crystal report.
I am saying this because all above option will work but you are still in the maximum reach so first of all delete all instance then apply all the above suggestion.
thanks
Make sure you are using PUSH model to display your reports. Next you have to make one change in your Server's registry: Follow the path:
"HKEY_LOCAL_MACHINE\SOFTWARE\SAP BusinessObjects\Crystal Reports for .NET Framework 4.0\Report Application Server\InprocServer"
and you will see an item " PrintJobLimit" and you will see that its default value is 75. that means the server can only handle 75 reports at a time.
Dont worry about that and just modify the value to -1
Make sure IIS user have sufficient permission to delete files present in "c:/windows/temp" folder.
I face the same issue once I provide write permission to that folder then it solved my issue.Also make sure dispose that object after generating the file
I was working on local report server. I have hosted my web application in other pc. When I got such error I just did IISRESET and working fine now.
Try this, this could help you.
You have to Dispose your report instance after all. If you Dispose the report after showing it, you will never see the error:

Code:
Dim report1 As rptBill = clsBill.GetReport(billNumber)
rpt.Print()
'Cleanup the report after that!
rpt.Close()
rpt.Dispose()
In my case, the report had 4 subreports...
What solved for me was changing the value of "PrintJobLimit", from 75 to 500, in the following Regedit paths:
\HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\SAP BusinessObjects\Crystal Reports for .NET Framework 4.0\Report Application Server\InprocServer
\HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\SAP BusinessObjects\Crystal Reports for .NET Framework 4.0\Report Application Server\Server
I know this thread is older, but if you configure the app pool setting "Recycling..." to recycle at, say, 180 minutes instead of 1740 minutes (the default), this might free up the needed resources.
Use These methods when unload the page
ReportDocument crystalReport;
protected void Page_Unload(object sender, EventArgs e)
{
if (crystalReport != null)
{
crystalReport.Close();
crystalReport.Dispose();
}
}
OR
protected void Page_Unload(object sender, EventArgs e)
{
if (crystalReport != null)
{
crystalReport.Close();
crystalReport.Clone();
crystalReport.Dispose();
crystalReport = null;
GC.Collect();
GC.WaitForPendingFinalizers();
}
}
I ended up using GC.WaitForPendingFinalizers in addition to the GC.Collect, close and dispose. I believe my web page was perhaps unloading and stopping thread processing prematurely before the garbage was properly processed (really?)

' yes, use of the GC.Collect (and even more the GC.WaitForPendingFinalizers) is highly controversial
'
' the reality is that rendering crystal reports is rather slow compared to most web operations
' so it is expected that waiting for GC will have relatively little performance impact
' and will in fact, help tremendously with memory management.
'
' try setting these values to 1 and confirm for yourself by instantiating multiple crDocuments in different browsers if you don't believe it:

'
' or google this error: The maximum report processing jobs limit configured by your system administrator has been reached
'
' I believe the problem is that on very fast servers, the page unloads and stops processing code to properly cleanup the Crystal Report objects
'
' This is done in 3 places:
' Report Viewer (Page_Unload and CrystalReportViewer1_Unload) rendering a report will of course always using a processing job
' Report Parameter Selector (Page_Unload) loading a crDocument without rendering a report still counts towards CR processing job limit.
' Custom Control crReportParameterSelectionTable (Public Overrides Sub dispose())

I am invoking a compiler command but the compiler messages are not getting displayed in the Eclipse Console View consistently.
I have my launch() method implemented the same way as first code block of
this question; I have the command-line string setup which I use to call DebugPlugin.exec() method. However, unlike the the author of the question above, my output Eclipse console is very inconsistent. T
There is no activity in the console when I invoke the command and the console continues to display the "No console to display at this time." But after invoking the command numerous time and activating different consoles from the drop-down menu, the console occasionally does become active and message is displayed.
I am confused with how the eclipse is behaving and not sure how to resolve this issue. Any comment and/or recommendation would be appreciated.
Thanks!!
--
EDIT
To add some more info, running the external process using External Tools works fine. I add the compiler process c:\path\myprocess.exe in Locations field and the file to compile in the Arguments field within the External Tools Configuration window. When I run it, all the output is displayed fine. It just won't display when I run it programmatically through LaunchConfigurationDelegate class.
Maybe try bringing the console to front programmatically see if it helps:
* Bring the console to front.
*/
public static void showConsole() {
Display.getDefault().asyncExec(new Runnable() {
#Override
public void run() {
IWorkbenchWindow window = CUIPlugin.getActiveWorkbenchWindow();
if (window != null) {
IWorkbenchPage page = window.getActivePage();
if (page != null) {
IViewPart consoleView =
page.findView(IConsoleConstants.ID_CONSOLE_VIEW);
if (consoleView == null) {
IWorkbenchPart activePart = page.getActivePart();
try {
consoleView =
page.showView(IConsoleConstants.ID_CONSOLE_VIEW);
} catch (PartInitException pie) {
CUIPlugin.log(pie);
}
// restore focus stolen by the creation of the
// console
page.activate(activePart);
} else {
boolean bringToTop = true;
if (bringToTop) {
page.bringToTop(consoleView);
}
}
}
}
}
});
}
Finally got it to work. The main change I've made is having my MyLaunchConfigurationDelegate extend LaunchConfigurationDelegate instead of just implementing ILaunchConfigurationDelegate. When observed through the debugger, the launch() method went through similar code path as external process that was launched via External Tools when MyLaunchConfigurationDelegate extended LaunchConfigurationDelegate.
I guess it was lack of information on my part but I wasn't sure which part of the code was more important to share.
Another piece of code that was removed was:
IProcess dbgProcess = DebugPlugin.newProcess(launch, compilerProcess, "XVR Compiler", processAttributes);
...
launch.removeProcess(dbgProcess);
I've added it while attempting different approach in debugging this issue and it actually caused more issues by removing the debugProcess before it has chance to display output to the console.
We're trying to play around with RIA Services. I can't seem to figure out how to delete a record. Here's the code I'm trying to use.
SomeDomainContext _SomeDomainContext = (SomeDomainContext)(productDataSource.DomainContext);
Product luckyProduct = (Product)(TheDataGrid.SelectedItem);
_SomeDomainContext.Products.Remove(luckyProduct);
productDataSource.SubmitChanges();
The removing the object from the Entity part works fine, but it doesn't seem to do anything to the DB. Am I using the objects like I'm supposed to, or is there a different way of saving things?
The error system is a little finicky. Try this o get the error if there is one and that will give you an idea. My problem was dependencies to other tables needing deletion first before the object could be. Ex: Tasks deleted before deleting the Ticket.
System.Windows.Ria.Data.SubmitOperation op = productDataSource.SubmitChanges();
op.Completed += new EventHandler(op_Completed);
void TicketsLoaded_Completed(object sender, EventArgs e) {
System.Windows.Ria.Data.SubmitOperation op = (System.Windows.Ria.Data.SubmitOperation)sender;
if (op.Error != null) {
ErrorWindow view = new ErrorWindow(op.Error);
view.Show();
}
}
In the code snippet above, I'd suggest using the callback parameter rather than an event handler.
productsDataSource.SubmitChanges(delegate(SubmitOperation operation) {
if (operation.HasError) {
MessageBox.Show(operation.Error.Message);
}
}, null);
The callback model is designed for the caller of Load/SubmitChanges, while the event is designed for other code that gets a reference to a LoadOperation/SubmitOperation.
Hope that helps...
