One general way would be to have the actions logically detached from the process assoicated with the browser. There are a number of different ways to accomplish this. One way would be to initiate an independent process to carry out the action, e.g. with a fork or a CreateProcess type of approach. Another way is to enter an "action request" into a "queue" and have an independently running process periodically check the queue for work to do and do it. The nature of the queue mechanism could vary all the way from a file that was created in a directory by the browser and deleted by the separate process to an entry stored in a database and deleted by the independent process when performed. Which mechanism was selected would depend on information you haven't provided. **** [EMAIL PROTECTED] <Carl Jolley> **** All opinions are my own and not necessarily those of my employer **** _______________________________________________ Perl-Win32-Users mailing list [EMAIL PROTECTED] To unsubscribe: http://listserv.ActiveState.com/mailman/mysubs
