[VB.NET] Negato l'accessso a certe cartelle. E l'esecuzione si interrompe

[alka]

Grazie per l'intervento. No alka, l'eccezione è gestita. Ma il problema permane

L'eccezione è gestita ma il problema permane, quindi è gestita male.

Non pubblichi altri dettagli né hai risposto ai dubbi esposti, quindi evidentemente non ti serve una mano.

Ecco. La funzione che interessa è questa. Non interviene più il debugger perchè, come ho detto, ho eliminato a mano le cartelle a cui era negato l'accesso
