Καλημέρα,
Αντιμετωπίζω ένα πρόβλημα με το Μελωδό στην διαδικασία αποθήκευσης εγγράφων. Αρκετές φορές, όταν παω να αποθηκεύσω ένα έγγραφο, ανοίγει ένα παράθυρο με το εξής μήνυμα·
"Unhandled exception has occurred in your application. If you click Continue, the application will ignore this error and attempt to continue. If you click Quit, the application will close immediately.
Object reference not set to an instance of an object."
Το αποτέλεσμα είναι ότι σε καμμία περίπτωση δεν μπορώ να αποθηκεύσω το έγγραφο, και αναγκάζομαι να το κλείσω και να ξεκινήσω ξανά από την αρχή (!).
Υπάρχει λύση για αυτό το πρόβλημα; Το έχει αντιμετωπίσει κανείς;
-Γαβριήλ
Υ.Γ. Όταν ανοίγει το παράθυρο με το μήνυμα που περιέγραψα, υπάρχει και ένα κουμπί που λέγεται "Details" (Λεπτομέρειες). Δεν ξέρω εάν είναι χρήσιμες, αλλά οι λεπτομέριες είναι ως εξής (συγχωρέστε με το μεγάλο κείμενο)·
See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.
For example:
<configuration>
<system.windows.forms jitDebugging="true" />
</configuration>
When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.
