Apologies if this isn't the correct area to post, but I'm in a bit of a rush. We have a hastily deployed app that uses the serial port to communicate to the Zebra RFD8500 scanner (not using SDK). We are seeing very frequent exceptions thrown in the field with a stack trace of:
Exception info: System.ObjectDisposedException
at System.Runtime.InteropServices.SafeHandle.DangerouAddRef(Boolean ByRef)
at System.StubHelpers.StubHelpers.SafeHandleAddRef9System.Runtime.InteropServices.SafeHandle, Boolean ByRef)
at Microsoft.Win32.UnsafeNativeMethods.GetOverlappedResult(Microsoft.Win32.SafeHandles.SafeFileHandle, System.Threading.NativeOverlapped*, Int32 ByRef Boolean)
We are awaiting our second scanner to arrive so we can try and reproduce this, but thought I would post for any ideas you may have?
thanks in advance!
