I'm running a web service with large data sets, and in order to speed up response to the user have added a method that merely validates the data and sends back a reply to tell the user to check back later to see if the data made it into the database.
What I'm doing is to fire up a new thread, passing the data to it, and then execution of the web service method continues and finishes while the new thread processes the data. This works fine, except when I want to log the new thread's progress by writing to a text file. I get a system event log entry description that says: Event Source: .NET Runtime 2.0 Error Reporting Description: EventType clr20r3, P1 aspnet_wp.exe, P2 2.0.50727.832, P3 461ef1db, P4 mscorlib, P5 2.0.0.0, P6 461eee3d, P7 331e, P8 15a, P9 system.unauthorizedaccess, P10 NIL. Oddly enough, if I make the app itself try to make an entry to the system event log the attempt fails with an event log entry that says: EventType clr20r3, P1 aspnet_wp.exe, P2 2.0.50727.832, P3 461ef1db, P4 system, P5 2.0.0.0, P6 461ef191, P7 3725, P8 115, P9 system.security.security, P10 NIL. I've set generous permissions on the target folder, and this doesn't seem to matter. Here's the source code starting up the thread: ExternalProxy p = new ExternalProxy(); ParameterizedThreadStart pts = new ParameterizedThreadStart(p.AddAGRBatchTransmission); Thread proxyThread = new Thread(pts); proxyThread.Start(batchTransmission); Any ideas how to give the spawned app enough permission to write to a log? Or a way to otherwise get around the security problem? =================================== This list is hosted by DevelopMentor® http://www.develop.com View archives and manage your subscription(s) at http://discuss.develop.com
