Elp,
In addition to the other comments.
Depending on the type of application you are creating, .NET has three
different global exception handlers.
For ASP.NET look at:
System.Web.Http Application.Err or event
Normally placed in your Global.asax file.
For console applications look at:
System.AppDomai n.UnhandledExce ption event
Use AddHandler in your Sub Main.
For Windows Forms look at:
System.Windows. Forms.Applicati on.ThreadExcept ion event
Use AddHandler in your Sub Main.
It can be beneficial to combine the above global handlers in your app, as
well as wrap your Sub Main in a try catch itself.
There is an article in the June 2004 MSDN Magazine that shows how to
implement the global exception handling in .NET that explains why & when you
use multiple of the above handlers...
http://msdn.microsoft.com/msdnmag/is...T/default.aspx
For example: In my Windows Forms apps I would have a handler attached to the
Application.Thr eadException event, plus a Try/Catch in my Main. The
Try/Catch in Main only catches exceptions if the constructor of the MainForm
raises an exception, the Application.Thr eadException handler will catch all
uncaught exceptions from any form/control event handlers.
Hope this helps

Hi,
I've developped a Window Form C# application which main form contains
several activex controls. No problems most of the time but on some
machine, the application crashes when the main form is closed with a
NullReferenceEx ception caused by the DisposeAxContro l which, i guess, is
supposed to dispose one of my ActiveX.
This is not a big problem as the application is closing anyway but i'd
like to suppress this crash message. However, i can't find a way to catch this
exception in my application. Even when putting the whole main method in a
try catch block, this exception is not catched! How can i catch all
unhandeled exceptions in an application?
