openning an application using a shell command

[Ohad Young]

Hi,

I need to open (launch) an external application from my winform application.
The application is not a dot.net application, for example the windows
calculator.

I'm using the System.Diagnost ics.Process class, for example:
....
System.Diagnost ics.Process proc = new System.Diagnost ics.Process();
proc.EnableRais ingEvents = false;
proc.StartInfo. WorkingDirector y = @"C:\WINDOWS\sy stem32\";
proc.StartInfo. Arguments = "some argument";
proc.StartInfo. FileName = "calc.exe";
proc.Start();
....

Is there a better way to do it?
How can I close the application programmaticall y?
Can I close it automatically when my application exits?

Thanks in advance, Ohad

No, not for the kind of control you want, I think; you've got it right.
How can I close the application programmaticall y?
proc.Kill();
Can I close it automatically when my application exits?
Sure, just call Kill() on some unload or exit event.

Thanks in advance, Ohad

Well certainly im doing the same as you to start a batch file. If you wanted
to stop the process a suggestion would be to move the

System.Diagnost ics.Process proc

to the Class scope and put a listener on the close event of your main
form... so.

this.Closing+=n ew CancelEventHand ler(MainForm_Cl osing);

private void MainForm_Closin g(object sender,
System.Componen tModel.CancelEv entArgs e)

{

proc.Close();

}

I stand corrected, kill then close ;-) And probably dispose too on the proc
object if its a closing event.

Hi Ohad,

Thanks for posting in this group.
For simple application such as calculator, the main window stands for its
program life. So you can use Process.CloseMa inWindow to require its main
window to close.
The behavior of CloseMainWindow is identical to that of a user closing an
application's main window using the system menu. Therefore, the request to
exit the process by closing the main window does not force the application
to quit immediately.
If CloseMainWindow fails, you can use Kill to terminate the process. Kill
is the only way to terminate processes that do not have graphical
interfaces.

Hope this helps,

Best regards,
