Hi, Use the JclAppInst unit from the JEDI library, in the dpr file just add two lines of code, the job will be done.
program MidServer; uses JclAppInst, //line one begin // Do not allow another instance to run JclAppInstances.CheckSingleInstance; //line two Monir -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Rainer von Saleski Sent: Sunday, September 23, 2007 10:14 PM To: [email protected] Subject: Preventing Multiple Simultaneous Executions What's the best (easiest effective) way to prevent multiple copies of a single Delphi program from attemtping to execute simultaneously? The problem is that users are double clicking to launch the program (when Control Panel is configured for single clicks), and then when things aren't happening fast enough, they click twice again, and again, and again, until there are 12 or more copies of the program trying to launch ... and none of them are getting off the ground. My users don't seem able to learn patience, so I need to help them out. Any ideas? Thanks, Rainer _______________________________________________ Delphi mailing list -> [email protected] http://www.elists.org/mailman/listinfo/delphi _______________________________________________ Delphi mailing list -> [email protected] http://www.elists.org/mailman/listinfo/delphi
