Restart Delphi Application Programmatically

Question

It should not be possible to run multiple instances of my application. Therefore the project source contains:

CreateMutex (nil, False, PChar (ID));
if (GetLastEr         


        

Answer 1

Your ReleaseMutex is probably failing since you're passing 'False' for 'bInitialOwner' while calling CreateMutex. Either have the initial ownership of the mutex, or call CloseHandle instead of 'ReleaseMutex' passing your mutex handle.
