If you wish to allow only one instance of your application can be run, use this component. TOneInstance also can catch the loading of new instances, get the new parameters and send them back the first instance for processing.

All you have to do is just put TOneInstance on your form, then give some codes for the eventOnNewInstanceLoad(NewAppHandle: Cardinal; NewCommandLineW: PWideChar). For more information, please visit the homepage.
