Hi,
I need to do some important cleanup before my console application
exists. I got some ideas from the groups and I used the console ctrl
event. This is working well and it fires for all cases, including the
CTRL_CLOSE_EVENT (if I close the application from the X botton). But on
the contrary to what the MSDN indicates, ending my process from the
task manager did not fire the CTRL_CLOSE_EVENT.
I also tried to use the Appdomain processexit, which didn't work for
any of the cases.
This is the code as I tried it:
public enum ConsoleEvent
{
CTRL_C = 0,
CTRL_BREAK,
CTRL_CLOSE,
CTRL_LOGOFF = 5,
CTRL_SHUTDOWN
}
public delegate void ControlEventHandler(ConsoleEvent consoleEvent);
public event ControlEventHandler ControlEvent;
ControlEventHandler eventHandler;
public ConsoleCtrlEventsSetup()
{
// save this to a private var so the GC doesn't collect it...
eventHandler = new ControlEventHandler(Handler);
SetConsoleCtrlHandler(eventHandler, true);
}
~ConsoleCtrlEventsSetup()
{
Dispose(false);
}
public void Dispose()
{
Dispose(true);
}
void Dispose(bool disposing)
{
if (disposing)
{
GC.SuppressFinalize(this);
}
if (eventHandler != null)
{
SetConsoleCtrlHandler(eventHandler, false);
eventHandler = null;
}
}
private void Handler(ConsoleEvent consoleEvent)
{
if (ControlEvent != null)
ControlEvent(consoleEvent);
}
[DllImport("kernel32.dll")]
static extern bool SetConsoleCtrlHandler(ControlEventHandler e, bool
add);
}
class CrashHandler
{
public static void
MyProcessExitHandler(ConsoleCtrlEventsSetup.Consol eEvent consoleEvent)
{
StopAllMotions();
}
public static void StopAllMotions ()
{
StreamWriter y = File.AppendText(@"c:\temp\test.txt");
y.WriteLine("stopping all motions");
y.Flush();
y.Close();
}
}
public static void Main()
{
ConsoleCtrlEventsSetup cc = new ConsoleCtrlEventsSetup();
cc.ControlEvent += new
ConsoleCtrlEventsSetup.ControlEventHandler(MyProce ssExitHandler);
Console.WriteLine("Press any key to exit");
}
Any ideas?
Thanks. 2 4378

Am I being a bit too obvious? Have you tried try ... finally?
public static void Main() {
try {
// Normal run code here
}
finally {
// Clean up code here
}
}

Any ideas? Thanks.

The ultimate truth is that there is no ultimate truth
Should work, make sure you stop the task from the Applications list, not the
process from the Process list.!
