    I have a program which generates GUID.Is there a chance that more than one thread spawned at the same time (< 1 millisec) in the same machine to have same GUID?. Thanks, Rane

      There is no chance, unless GUID generation mechanism is broken, I guess. Why don't you make a little test? :)

        I don't think so. The GUIDs will be different.
