Need help with ApplicationExce ption

[Charles]

I need to find a way to share information between two classes, one is an
employee class and the other is a custom error class that inherits from
ApplicationExce ption. These two classes are part of a ClassLibrary project.
The other project has all the web page classes.

My project allows employees to log in using Forms Auth, I do some checking
on the person that is logging in and then after that is good I create an
employee object and that is stored in a session variable.

What I would like is if this employee that logged in gets an error message
at anytime during their use of the web site that the error gets logged with
their userid name. I can log errors and all that, I am logging them to a
database. What I need is just how do I get the error message with the userid
name.

Thanks,
Charles

Okay, I'm assuming that somewhere in this employee object stored in a
session variable is the "userid name." If so, and you're creating your own
custom Exception class (why are you inheriting ApplicationExce ption instead
of Exception?), you can create a field named "userid" in the custom
Exception class, and implement a constructor method that includes the
"userid" as a parameter. Then in your Try/Catch (you ARE using Try/Catch,
aren't you???), you do something like the following:

catch (Exception ex)
{
throw new MyCustomExcepti on(ex.Message, ex,
((employee)Sess ion["CurrentEmploye e"]).userid);
}

Of course, what you do with your new Custom Exception is up to you, but I
hope you get the idea.

Thank you for your reply!

Yes there is a "userid name" variable in the employee object.

I am not sure why I am using ApplicationExce ption instead of Exception. The
only reason that I do have is that I found it on an example. Why should I be
using Exception and not ApplicationExce ption?

I wanted to try to avoid implementing a constructor method that includes the
"userid" as a parameter and having other programmers remember how to add the
userid to a Throw New line. But, if there is no other way to do it besides
the way that you explined that I guess I am stuck doing it that way. I am
using a Try/Catch block.

I was hoping for something along these lines,
Public Class InvalidRetrieve Exception
Inherits ApplicationExce ption

Public Sub New()
MyBase.New()

End Sub
Public Sub New(ByVal message As String, ByVal InnerException As
Exception))
'_userName comes from Employee object (somehow)
MyBase.New(mess age & ": " & _userName, InnerException)
WriteToLog(mess age & ": " & _userName, InnerException)
End Sub

End Class

Thanks again,
Charles
