I need to add the ability to cancel a job which is running. My first attempt works, but it takes a while for the module to stop. Has anybody done anything similar or could offer any advice on where I am going wrong?

The below code snippet shows how my current methodology works. (It is nicely tabbed on my machine but the forum seems to have removed them all...)

The module c:\TestModule.yxmd takes 1:45 hours to run via the gui.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading;
using System.Runtime.InteropServices;

namespace CancelJob
{
class Program
{
static void Main(string[] args)
{
Module TestModule = new Module(@"c:\TestModule.yxmd");
Thread RunModuleThread = new Thread(new ThreadStart(TestModule.Run));
Console.WriteLine(DateTime.Now.ToString() + " Starting Thread");
RunModuleThread.Start();
Thread.Sleep(5000);
Console.WriteLine(DateTime.Now.ToString() + " Aborting Thread");
RunModuleThread.Abort();

while (RunModuleThread.ThreadState != ThreadState.Aborted && RunModuleThread.ThreadState != ThreadState.Stopped)
{
}
Console.WriteLine(DateTime.Now.ToString() + " Thread Aborted");
Console.ReadKey();
}
}

class Module
{
string Path;

public Module(string _Path)
{
Path = _Path;
}

public void Run()
{
try
{
Alteryx.AlteryxApi.CallbackMessage pCallbackMessage = new Alteryx.AlteryxApi.CallbackMessage(this.CallbackMe ssage);
Alteryx.AlteryxApi.AlteryxRunModule2(Path, null, null, pCallbackMessage, 0);

}
catch (ThreadAbortException err)
{
Console.WriteLine(DateTime.Now.ToString() + " ThreadAbortException caught");

}
catch
{

}
}

private int CallbackMessage(System.Int64 userData, System.Int32 nToolId, Alteryx.AlteryxApi.E_CallbackStatus nStatus, [MarshalAs(UnmanagedType.LPWStr)]string pMessage)
{
return 0;
}
}

}

The above code produces this:

07/09/2010 08:30:45 Starting Thread
07/09/2010 08:30:50 Aborting Thread
07/09/2010 09:02:00 ThreadAbortException caught
07/09/2010 09:02:00 Thread Aborted

So it's taking about half an hour for the thread to abort. Next stage I'm thinking of looking at is the other api method for running jobs, but thought I would see if anyone here had any ideas first.

Thanks
