c# - Windows Service Exception Handling and Timers -


I have a problem with System.Timers.Timer does not throw any exceptions in this here: My code is here: < / P> 

  Private Timer Mitimer {Receive; Set; } Public MyService () {InitializeComponent (); AppDomain.CurrentDomain.UnhandledException + currentDomain_UnhandledException; MyTimer = New Timer (10 * 1000); MyTimer.Elapsed + = MyTimer_Elapsed; } Safe Override Zero Onstart (string [] args) {MyTimer.Enabled = true; } Private Zero CurrentDomain_UnhandledException (Object Sender, UnhandledExceptionEventArgs e) {if Event! LoggerLock.Com } EventLog.WriteEntry (EVENTLOGSOURCE, "UnhandledException \ r \ n" + e.ExceptionObject, EventLogEntryType.Error); EventLog.WriteEntry (EVENTLOGSOURCE, "Unlocked Expressionergart.Etestimating:" + E.I.S.Termitting, Event LogENTER TypeError); If (EITTETING) {this.ExitCode = 100; //this.Stop (); }} Private Zero MyTimer_Elapsed (Object Sender, ElapsedEventArgs e) {MyTimer.Enabled = false; CurrentDomain_UnhandledException (AppDomain.CurrentDomain, New UnhandledExceptionEventArgs (New Exception ("FakeExceptionForTestPurposeOnly: It Will Be Logged!", False)); Int32 i = Convert ToInt32 ("10_ForSureGeneratesException_10"); }

Then, in my event log "FakeExceptionForTestPurposeOnly: it will be logged!" But this is only one!

After that, the bad part is the service that is still going on. How is this possible? Please note I have already solved this problem, in that case the use of the timer is not mandatory. threading. Thread trick and works as a clockwork. I'm just curious ...

The question is then: Why MyTimer_Elapsed () "CurrentDomain_UnhandledException (Object Sender, UnhandledExceptionEventArgs e ) Will never be removed during the event of any uncontrolled exception

Any help, suggestions, comments will be appreciated

< Div class = "post-text" itemprop = "text">

In a Windows service, the "main" thread is owned by service control manager , Which calls onstart and OnStop methods. When an exception occurs on the "Main" thread, then Servicebase is in charge of dealing with class exceptions, thus takes care of the exception and does not promote the call series.

Although there should be no synchronization context inside a Windows service, hence the Elapsed event is set on a separate ThreadPool thread Should be removed, I can suggest instead, you are trying to do System.Threading.Timer , and see that the exception spreads when Elapsed events Calls callback.

c# - Showing a SelectedItem's Property -

So I have enabled a rightclick option for my DataGrid. I want to display the only chosen property but it is not behaving like what I would like it to display my name and additional. Public category Paymentinfo {public int PaymentNo {get; Set; } Public string date {get; Set; } Public Double Pay {get; Set; } Public Double Principle {get; Set; } Public Double Interest {get; Set; } Public Double Balance {Received; Set; }} Private Zero MenuItem_OnClick (Object Sender, RoutedEventArgs e) {MessageBox.Show (AmortGrid.SelectedItem.ToString ()); } I'm trying to apply it without using a View Module! If I place a breakpoint where the messagebox and the recipient place it on selected ITEM, then this property will display the payment. A date-payment-principle-interest-balance is the only value that needs payment. Was hoping that it would be something like this MessageBox.Show (AmortGrid.SelectedItem.PaymentNo.ToString ()); When you call ToString () So you get the class typ
