Err.Number -2147217873

Hi,

In asp I am catching the error that is thrown by COM+ component. I am getting the error number as
-2147217873. I know why this error is coming(Due to unique constraint error in database). But my doubt is whether this error number is common for all runtime errors or it signifies some specific kind of error. Can anyone put some light on this? Also can I get a list of all possible error numbers (ofcourse excluding user defined) along with its description?
