Rodrigo,

I'm not sure what you mean by global error handler. If you want to put one
in that will catch any error not captured by a *local* Try/Catch structure,
you can put one in ApplicationEven ts.

Exceptions bubble up the call tree until they are handled (or they hit the
top and blow up). The top of the tree is in ApplicationEven ts, where you
can add an event handler for unhandled exceptions.

To get to the ApplicationEven ts, double-click on "My Projects" to bring up
project properties, then select the tab "Applicatio n", and click on the
button "View Application Events".

To see what events you can capture, pull down the left dropdown at the top
and select "(MyApplica tion Events)". Then pull down the right dropdown at
the top. The one you want is UnhandledExcept ion.

There are also events for the application starting up and shutting down,
etc.

Is this what you're looking for?

Hi Rodrigo,

Glad to see your problem is resolved. Below is some more information:

Actually, VB2005 UnhandledExcept ion encapsulates .Net Winform
Application.Thr eadException. .Net provided 3 different types of global
error handler for unhandled exceptions based on the application types.

..Net Winform -- Application.Thr eadException event
..Net Console -- AppDomain.Unhan dledException event
Asp.net -- HttpApplication .Error event, which is defined in Global.asax as
Application_Err or method.

Please refer to the article below:
"Unexpected Errors in Managed Applications"
http://msdn.microsoft.com/msdnmag/issues/04/06/NET/

Hope this helps.

Best regards,
Jeffrey Tan

Application_Error event in global.asax.cs

There appear to be several ways to get the global error handler in global.asax.cs to fire repeatedly in a nasty endless loop. Is there a way to keep this event from firing only a handful of times over the course of a minute, so that if it's obviously caught in a vicious loop, it will stop? In our global error handler, we send an email warning developer's of the problem. However, if the global error handler fires repeatedly, we get...

Global subroutines

by: fd123456 | last post by:

Er... Sorry to interrupt, but you CAN put methods and functions in the Global.asax file. You just have to make them static (Shared in VB). You can even use functions normally not available outside of a page, like LoadControl, like this : in an aspx code-behind file, for instance in the Page_Load handler : System.Web.UI.Page p = this; bool IsLoaded = Global.GlobalMethod(ref p);
