I have been looking for a way to detect when the a console application has ended. I want the ability to do some cleanup. Similar to Application.ApplicationExit in forms applications. I've scoured google, code project, msdn, etc. but no solid solution.
I thought about simply launching a cleanup thread at the start of the program and have it Join the main thread. Once that happens perform cleanup. I tried a test application (see code below):
static void Main(string[] args)
{
Thread cleanupThread = new Thread(cleanupThreadStart);
cleanupThread.Start(Thread.CurrentThread);
Thread.Sleep(5000);
Console.WriteLine("Main: Ended.");
}
private static void cleanupThreadStart(object state)
{
Thread mainThread = (Thread)state;
Console.WriteLine("cleanupThreadStart: Waiting for main thread to exit.");
mainThread.Join();
Console.WriteLine("cleanupThreadStart: Ended.");
}
Oddly, this solution works from within VS when I start with debugging (F5), meaning that the main thread will end and the cleanup thread will complete the join and I'll see the console printout. However if I start without debugging (ctrl+F5 or simply run the executable directly) the program hangs because the main thread ends but the cleanup thread never completes the Join. I've tried attaching to the process from within VS during the hang and I can see that the main thread is no longer present but the cleanup thread is still waiting for the Join to complete.
Does anybody know why this works with debugging active but not without it? Does anybody have any other clever way of detecting that the application is about to end (similar to Application.ApplicationExit)?
For now I've got a workaround to just create my own "main" thread which executes the normal application code. Then my cleanup thread joins with this thread before cleanup. This seems to work fine.

I'm interested in this sort of thing myself - one of the things I found was
class Program
{
static void Main(string[] args)
{
AppDomain.CurrentDomain.ProcessExit += new EventHandler(CurrentDomain_ProcessExit);
<pre>
}
static void CurrentDomain_ProcessExit(object sender, EventArgs e)
{
Console.WriteLine("exit");
}
}</pre>
Im also working on handling the Ctrl/C, Ctrl/Break, 'X' to detect app shutdown as well

When the debugger is attached, it will keep the main-thread alive, since you're debugging. Without the debugger, the main-thread is halted. The application will close as soon as all foreground threads close.
There is no event that says that a console-application is about to be aborted with Ctrl-C. The mainthread is simply terminated; hence it will not execute any events.

So start with Google, and see what you can find: we aren't a "code-to-order" service - we expect you to put in some effort!

Next time will take care of these points.
Thanks..!!

OK....I would appreciate if you could tell me in what way I can ask a question.
Thanks for your precious time.

When I load the data onto the gridView if the string contains a newline character, and the first line ("\r\n"), the grid in the first row of the gridView down the line when viewed slightly inconvenient to stretch the new grid see lines that are hidden, you want to stop in the gridView grid phenomenon is not ? (Ie if there is a newline character and the beginning of a line also appears on a single line of gridView), instead I have to write more code to browse all the columns in the grid newline character removed and the beginning of the line . Can you help me ?

No, because I have no idea what you are trying to say.
Perhaps an example with what you input, what you get, and what you would like would help?

I'm writing code read data of gridView1 has got using Thread but get an error:
[CODE]
// old-style writing
if (string.IsNullOrEmpty(gridView1.GetRowCellValue(i, "Ghichu").ToString()))
//new style writing
if (string.IsNullOrEmpty(GetGridCellValue(i, "Ghichu").ToString()))
//Declare complement the new style writing
public delegate void GridGetEventArg(int rowHandle, string fieldname);
private string GetGridCellValue(int row, string fieldname)
{
if (gridControl1.InvokeRequired)
{
GridGetEventArg get = new GridGetEventArg(GetGridCellValue); //Error 1 'string Vidu.frmTinh.GetGridCellValue(int, string)' has the wrong return type
return gridControl1.Invoke(get, new object[] { row, fieldname });//Error 2 Cannot implicitly convert type 'object' to 'string'. An explicit conversion exists (are you missing a cast?)
}
else
{
return (gridControl1.MainView as GridView).GetRowCellValue(row, fieldname);//Error 3 Cannot implicitly convert type 'object' to 'string'. An explicit conversion exists (are you missing a cast?)
}
}
[/CODE]
the help you fix ?

Well, the first problem you have is that you defined your GridGetEventArg as a void method, so it doesn't return anything. You can't assign a void to anything.
The second error you are seeing where it tells you that it cannot implicitly convert an object to a string is because you are returning an object from GetGridCellValue, but your method actually expects to return a string so you'd have to either change your method to return object or you need to call ToString() before returning;
