I would really appreciate any comments since I am quite stuck with this problem.

Thanks again.

Thanks very much for making WmAutoUpdate available. I’ve incorporated it into my current project and it works very nicely indeed!

I don’t have a lot of experience with Windows programming and in particular events and threading so I’m having a little trouble following the code. I’ve got a problem that I can’t seem to resolve.

If I cause the application to crash half-way through updating it is supposed to recover by copying the backup version back into the main directory. This doesn’t work because the exe file is “locked” by the operating system because it is currently in use. I can verify this is the case because I can’t delete it using Windows Explorer either. The error details are:

System.IO.IOException was unhandled
Message=”IOException”
StackTrace:
at System.IO.__Error.WinIOError(Int32 errorCode, String str)
at System.IO.File.Move(String sourceFileName, String destFileName)
at WmAutoUpdate.Updater.assertPreviousUpdate()
at WmAutoUpdate.Updater..ctor(String url)

The error occurs on this line in Updater.assertPreviousUpdate():
File.Move(f, appPath + “\\” + getFilenameFromPath(f));

To be honest I’m amazed that you were able to copy/delete the application exe file while it was running but I can see that the code manages to do this somehow when it updates the application. The problem is that it doesn’t work when rolling back. Do I need to do it in another thread or something?

Thanks again.
