System Error Code number.

An error message alerts users of a
problem that has already occurred.
By contrast, a warning message
alerts users of a condition that
might cause a problem in the
future. Error messages can be
presented using modal dialog
boxes, in-place messages,
notifications, or balloons.
A typical modal error message.
Effective error messages inform
users that a problem occurred,
explain why it happened, and
provide a solution so users can fix
the problem. Users should either
perform an action or change their
behavior as the result of an error
message.
Well-written, helpful error
messages are crucial to a quality
user experience. Poorly written
error messages result in low
product satisfaction, and are a
leading cause of avoidable technical
support costs. Unnecessary error
messages break users' flow.
System error codes are provided to
software programmers as part of
the programming interface with
the Windows operating system . In
other words, system error codes
are predefined error codes and
error messages that software
programmers can use with their
software to tell you (the software
user) that the program is
experiencing a particular problem.
Not every software program uses
these predefined system error
codes. Some software programs
have their own sets of error
numbers and error messages.
