Handling exceptions

Hi,

I need some help in this - I have a base abstract class in VB.Net and a
bunch of derived classes inheriting from the base class. One method in the
base class is overriden in the derived class. This method calls other methods
of base class.
Effectively,

MustInherit Class BaseAbstract

Sub Method1()
code..............
Method2()
code..............
End Sub

Sub Method2()
code..............
Method3()
code..............
End SUb

Sub Method3()
code..............
End Sub

Overridable Sub Method ProcessFile()

End Sub
End Class

Class Derived1 : inherits BaseAbstract

Overrides Sub ProcessFile()

'open file
'loop thru the file by reading one line at a time
do while
code................
Method1()
more code..............
loop
End Sub

End Class

My Q is - Where do I handle exceptions? Say for instance, an error occurs in
Method3. Where do I handle this error and if I do it in the method in the
base class, I'll need to inform the Derived class method i.,e original caller
that an error occurred and must skip this and go to next record/line from the
file.

Thanks.
