Difference between error handling and exception handling

[jsknight1969]

I'm not sure of the technical difference, but I believe they are just a difference in languages. VBScript/ASP is an Error object. Other languages that are object oriented (.NET, C++, Java) (3GL) use an exception object for errors.

VBScript example

Code:

on error resume next
a = 1/0
if err.number <> 0 then
  msgbox err.description
end if

VB.NET example

Code:

Try
  a=1/0
Catch (ex as exception)
  msgbox ex.message
End Try

C#

Code:

try
{
  a=1/0
}
catch (exception ex)
{
  msgbox ex.message
}

The exception is more powerful. It is also not dependent on the vague and often odd Microsoft Error codes to trigger a handle condition. For example, you can actually test for an exception of type System.IO.Exception instead of trying to case all the -214XXXXX error codes.

Hope this helps.
