[ADVANCED-DOTNET] Which way is the better way to trap all unexpected exception !

[Th�i Tr� H�ng]

Hi all , 
I'm looking for a way to trap all unexpected exception , and I found two
: 

- The first is trap at the appliction run point : (C# code)
     
[STAThread]
static void Main() 
{ 
        try
        {
                string strConnect="Provider=Microsoft.Jet.OLEDB.4.0;Data
Source=db.mdb;Persist                 Security Info=False;";
                OleDbConnection conn=new OleDbConnection(strConnect); 
                conn.Open();
                Application.Run(new MainForm(conn));
        }
        catch(Exception ex)
        {
                BugTracking.LogException(ex);
                Application.Exit();
        } 
}

- The second is use OnThreadException (VB.NET code)

AddHandler Application.ThreadException, AddressOf Me.OnThreadException
...

Sub OnThreadException(ByVal sender As Object,_
                            ByVal t As
System.Threading.ThreadExceptionEventArgs)
        BugTracking.LogException(t;
        Application.Exit();             

End Sub


Could anyone explain me which way is better - I guest is is the same ?

And a further question - how can I determine when I must use
Appliction.Exit and when I can let user continue his job ? (In VB6.0 I
know a good mechanism to do that but I can not use this in .Net or I
don't know how to do that - may be ) 

Save me !
