Hello all.
I have a application written in the 3.5 Compact Framework running on Windows
Mobile devices. VB.NET VS 2008.
The application communicates with our server using the
System.Net.Sockets.TcpClient class
This code used to communicate works flawlessly in our regular windows
application. It also works wonderfully when the device (Treo 700 is my test
case) is plugged into a PC with the USB cable. When not plugged in and
using the internet over the cell phone it will occasionally crash with:
ObjectDisposedException
at System.Threading.Timer.throwIfDisposed()
at System.Threading.Timer.Change(UInt32 dueTime, UInt32 period)
at System.Threading.Timer.Change(Int32 dueTime, Int32 period)
at System.Net.HttpWebRequest.startReadWriteTimer()
at System.Net.HttpWebRequest.ConnectionClient.Read(Byte[] data, Int32
offset, Int32 length)
at System.Net.HttpReadStream.NetworkRead(Byte[] data, Int32 offset, Int32
length)
at System.Net.ChunkedReadStream.fillBuffer()
at System.Net.ChunkedReadStream.getLine()
at System.Net.ChunkedReadStream.doRead(Byte[] data, Int32 offset, Int32
length)
at System.Net.HttpReadStream.ReadToDrain(Byte[] buffer, Int32 offset,
Int32 length)
at System.Net.HttpReadStream.doClose()
at System.Net.HttpReadStream.Finalize()
It may work great a few times - then crash like this. This error appears
untrappable - all my code is Try/Catched. We don't believe this was a issue
in previous versions of the framework but this is our first release using
2008/3.5 so it's hard to say for sure.
Anyone out there have a clue as to what may be causing this and what steps I
can take to trap the error and/or prevent it?
Thanks so much in advance.
Bob
