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 ApplicationEvents.

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 ApplicationEvents, where you
can add an event handler for unhandled exceptions.

To get to the ApplicationEvents, double-click on "My Projects" to bring up
project properties, then select the tab "Application", 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 "(MyApplication Events)". Then pull down the right dropdown at
the top. The one you want is UnhandledException.

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 UnhandledException encapsulates .Net Winform
Application.ThreadException. .Net provided 3 different types of global
error handler for unhandled exceptions based on the application types.

..Net Winform -- Application.ThreadException event
..Net Console -- AppDomain.UnhandledException event
Asp.net -- HttpApplication.Error event, which is defined in Global.asax as
Application_Error 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
