Problem beim Programmneustart mit Instanzkontrolle

[Sir Rufo]

Ich würde vor dem Aufruf des Programms den Mutex wieder freigeben ...

BTW

Den Code in finalization kannst du dir sparen, denn

Zitat:

Use the CloseHandle function to close the handle. The system closes the handle automatically when the process terminates. The mutex object is destroyed when its last handle has been closed.

schön ist auch

Zitat:

If you are using a named mutex to limit your application to a single instance, a malicious user can create this mutex before you do and prevent your application from starting. To prevent this situation, create a randomly named mutex and store the name so that it can only be obtained by an authorized user. Alternatively, you can use a file for this purpose. To limit your application to one instance per user, create a locked file in the user's profile directory.
