Ciao a tutti,
devo aprire un excel e salvarlo con i dati presi da DB

scrivo Excel.ApplicationClass oExcel = new Excel.ApplicationClass() ;
.....altre istruzioni

vado in debug e mi dice:

Access is denied.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.UnauthorizedAccessException: Access is denied.

ASP.NET is not authorized to access the requested resource. Consider granting access rights to the resource to the ASP.NET request identity. ASP.NET has a base process identity (typically {MACHINE}\ASPNET on IIS 5 or Network Service on IIS 6) that is used if the application is not impersonating. If the application is impersonating via <identity impersonate="true"/>, the identity will be the anonymous user (typically IUSR_MACHINENAME) or the authenticated request user.

To grant ASP.NET write access to a file, right-click the file in Explorer, choose "Properties" and select the Security tab. Click "Add" to add the appropriate user or group. Highlight the ASP.NET account, and check the boxes for the desired access.

ho messo i permessi ma non ottengo nulla...

Aiuto!!!

grazie a tutti.

saluti

(In fase di debug non si presenta)

Lato server, quando eseguo l'istruzione
