Please,
someone knows if ther'is a Windows API to know if an Handle exists? I mean that : i want to check i fan application is already running on system. I had idea to save in Local Database [i need to use a Database for other reasons] the Application.Handle. So when a copy of application starts, it checks in Database and read the last Handle written. Then i thought it could check by some (which one?) if that Handle is currently used. Really i have already an other mechanism to check it : the applicatio writes every TOT seconds in Database a TDateTime field by currently value returned by Now(). Then i used a field named 'Actived' to reset whenthe Application ends. Well, i'd like to have a stronger control by using even the Handler for cases which in the application faults and become not capable to reset the 'Actived' flag. I think it's possibile an Handler (with same value of expired Application) can be used by other applications, but at least i can be really sure [when even Handler-checking works] that the old Application was faulted. I hope someone can help me. Thanks.
