Getting AppDomain.UnhandledException event to work in a Windows Service

Posted By:      Posted Date: August 28, 2010    Points: 0   Category :.NET Framework
Nearly every forum thread I have found on "catching unhandled exceptions in a service" seems to end up where I am.  The supposed solution is the use of the AppDomain.CurrentDomain.UnhandledException event.  But it doesn't work for someone, who then asks why and gets no answer.  Same for me; I can't get the event to happen.  It's as if I need the ServiceProcess version of Application.SetUnhandledExceptionMode(), which doesn't exist. For diagnosing this, I start a timer in a child object of the service and then throw an exception in the timer event handler.  Simple enough to simulate the real situation.  I have tried subscribing to the UnhandledException event in at least a half dozen locations throughout the service, from the Program that runs ServiceBase.Run() to the constructor of the object that owns the Timer, but it never catches this exception. The VS debugger recognizes that the forced exception is unhandled and takes me to the place where is thrown, letting me know it is an unhandled exception. Why doesn't my handler catch it?  Running without the debugger, the exception throws, the timer thread crashes, the service continues merrily along, and nothing gets logged anywhere.  That is NOT the result I need.  What are the people for whom this works doing that I am not doing? How can I at least get the offe

logoff doesn't work through windows service

Dear Friends, I am facing this problem on Windows 2003 and 2008 Server. On XP it works fine. I have written and Windows Service that takes receives the command and executes tasks such as Logoff, Shutdown, etc. All the commands except Logoff works fine. I tried following ways to perform the Logoff. However it didnt work. Try 1:                 Process.Start("shutdown", "-l"); Try 2:     [DllImport("user32.dll")]     public static extern int ExitWindowsEx(int uFlags, int dwReason);     ExitWindowsEx(0, 0); Try 3:     Process _currentProcess = new Process();                _currentProcess.StartInfo = new ProcessStartInfo("shutdown", "-l -f");                _currentProcess.StartInfo.UseShellExecute = false;                 _currentProcess.Start(); Try 4:     Process.Start("logoff.exe", null); If I write a simple C# based applicatin (not Service) it works fine for all the tries that I have made. I am facing this problem only when I put this code

Windows Service Applications Tutorials

You can easily create services by creating an application that is installed as a service. For example, suppose you want to monitor performance counter data and react to threshold values. You could write a Windows Service application that listens to the performance counter data, deploy the application, and begin collecting and analyzing data.

Windows Services: New Base Classes in .NET Make Writing a Windows Service Easy


Windows services are applications that run outside of any particular user context in Windows NT, Windows 2000, or Windows XP. The creation of services used to require expert coding skills and generally required C or C++. Visual Studio .NET now makes it easy for you to create a Windows service, whether you're writing code in C++, C#, or Visual Basic. You can also write a Windows service in any other language that targets the common language runtime. This article walks you through the creation of a useful Windows service, then demonstrates how to install, test, and debug the service.

file upload in Create User Wizard Created User event with UpdatePanel Tag wont work?



In my Create User Wizard1 Created User Wizard Event, I am collecting extra information from text boxes and allowing

the user to uplad a file.



I have put the Submit button within an Update Panel Tag but since I have done this it does not work.

Is there a way round it. In this situation would you use a trigger.?


<br />

  <asp:UpdatePanel ID="UpdatePanel2" runat="server">

  <asp:Button ID="StepNextButton" runat="server"  CommandName="MoveNext"  align="middle"
                                            Text="Submit my Profile" />

Windows SharePoint Services 3 Search Event ID 2424


This error started on 29 April and I cannot get rid of it...  My search works fine, both site and people.  AD profile import works fine.  Full and incremantal crawls work as scheduled.  Just that this error keeps showing up every five minutes in one of two WFE's.  The other WFE does not receive this error


I have verified all Security Configuration/Service Accounts, verified all Services on Server/Search accounts, Stopped/Restarted all search, and verified SSP accounts.  The last thing I did was verify there was an indexer attached to the SSP...

I set the diagnostic logging to verbose and the only thing that stood out around the time of the error was

System.Data.SqlClient.SqlException: Invalid object name 'AR_CacheCounters'.

SqlError: 'Invalid object name 'AR_CacheCounters'.'    Source: '.Net SqlClient Data Provider' Number: 208 State: 1 Class: 16 Procedure: 'proc_ar_GetCacheInvalidationCountersWithCount' LineNumber: 3 Server: 'SERVER'


Any suggestions?







How to get Click event to work with checkbox


I am new to ASP.Net and I'm having trouble figuring out what needs to be where in my code.  I have a webform with 2 listboxes and 2 checkboxes... When I check checkbox1 I want listbox1 to be disabled and checkbox2 to be disabled.  Similarly, when I check checkbox2 I want listbox2 to be disabled and checkbox1 to be disabled.  The code does not show any errors; however, when I run the Page everything appears as it is supposed to but when I check the boxes, nothing happens.  What am I missing that will link the code on the .aspx.vb page to the objects on the .aspx page and make them work together?

Here is my code for Page1.aspx.vb:

Public Class LCPage1
    Inherits System.Web.UI.Page

Windows Identity Foundation Security Token Service can't stay logged in

I'm using the Windows Identity Foundation **(WIF)** Security Token Service **(STS)** to handle authentication for my application which is working all well and good. However I can't seem to get any long running login with the STS. From my understanding I shouldn't care about the client tokens at the application level since they can expire all they want to and it should redirect me to the STS and as long as they're still logged in on the STS it should refresh their application token. Yet it doesn't seem to want to keep them signed in. Here's what occurs in my login.aspx on the STS var cookie = FormsAuthentication.GetAuthCookie(userName, persistTicket); if (persistTicket) cookie.Expires = DateTime.Now.AddDays(14); Response.Cookies.Add(cookie); var returnUrl = Request.QueryString["ReturnUrl"]; Response.Redirect(returnUrl ?? "default.aspx"); Which was taken almost directly from existing application using normal Forms Auth. From my web.config <authentication mode="Forms"> <forms loginUrl="Login.aspx" protection="All" timeout="2880" name=".STS" path="/" requireSSL="false" slidingExpiration="true" defaultUrl="default.aspx" cookieless="UseDeviceProfile" enableCrossAppRedirects="false" /> </auth

Cash Drawer - Method Open threw an exception - Windows Service

Hi All, I'm getting the following exception while calling Open method of Cash Drawer object. Method Open threw an exception.  Could not read the device name key's default value, or could not convert the Programmatic ID it holds into a valid Class ID. Code:   class Class1 { CashDrawer _uniCashDrawer1 = null; DeviceInfo cashDrawerDevice1 = null; PosExplorer posExplorer = new Microsoft.PointOfService.PosExplorer();   public void ClaimCashDrawer() { cashDrawerDevice1 = posExplorer.GetDevice("CashDrawer", "testDrawer"); if (cashDrawerDevice1 != null) { _uniCashDrawer1 = posExplorer.CreateInstance(cashDrawerDevice1) as CashDrawer; if (_uniCashDrawer1 != null) { _uniCashDrawer1.StatusUpdateEvent += new StatusUpdateEventHandler(UniCashDrawer1_StatusUpdateEvent); _uniCashDrawer1.Open(); _uniCashDrawer1.Claim(0); _uniCashDrawer1.DeviceEnabled = true; } } } }   Tha above code works fine if you put the code in WindowsApplication in all POS systems. The same is working if you put the code in Windows Service in all other POS systems. The same is not working if you put the code in Windows Service in Aures Galeo POS systems.  Thanks in advance.
