Nenad,
In addition to the other comments:
My idea was to have exception which is logged (in file) every time when
it is thrown, without any other actions.
If one has to log exception every time he catch it, it is possible for
him to forget to log it. Beside, it is the same code in every catch()
block, so it is dull and tiresome.
Depending on the type of application you are creating, .NET has three
different global exception handlers.
For ASP.NET look at:
System.Web.HttpApplication.Error event
Normally placed in your Global.asax file.
For console applications look at:
System.AppDomain.UnhandledException event
Use AddHandler in your Sub Main.
For Windows Forms look at:
System.Windows.Forms.Application.ThreadException 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/issues/04/06/NET/default.aspx
For example: In my Windows Forms apps I would have a handler attached to the
Application.ThreadException 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.ThreadException handler will catch all
uncaught exceptions from any form/control event handlers.
Hope this helps
