asp error handling

[Rob]

I have the following code that works well when I run it on localhost,
but when I browse to it from another computer i get the error message
below.

Dim objUser As New DirectoryEntry("LDAP://cn=myName,ou=Tech
Support,dc=mydomain,dc=com")
Try
objUser.Invoke("ChangePassword", Oldpass.Text,
newpass.Text)
objUser.CommitChanges()
Catch ex As Exception
Response.Write(ex.InnerException.Message)
End Try

Here's the error I Get. It's like ex is no longer exposed. What can I
do to handle different types of errors if I cannot use ex?

Object reference not set to an instance of an object.
Description: An unhandled exception occurred during the execution of
the current web request. Please review the stack trace for more

Rob,

First off you're providing unecessary details to the public about your
passwords. Security best practice for passwords is to write the same error
message no matter what the error is. response.write("Sorry, A problem
occured please try again later.")

Your error was in design not all errors have innerexception or
innerexception.message property initialized

Good Luck
