Hi,

I am using .Net 2005 and I am working on Windows application

If I am calling any other application from my application using

System.Diagnostics.Process.Start(Application.StartupPath + @"\Decrypt\vb_passwordDcrypt.exe");

This is starting my application made in .Net 2003

I want that when this application exists then I must know, that the application I opened is closed now

Can I find this in my application

Kind Regards,

System.Diagnostics.Process FProcess =
                new System.Diagnostics.Process();
            FProcess.StartInfo.FileName = Application.StartupPath + @"\Decrypt\vb_passwordDcrypt.exe"
            FProcess.Start();
             FProcess.Kill();//if u want to kill the other process
            FProcess.WaitForExit() //waits till it exists
            FProcess.HasExited // gets whether the other application has exited

and u get many other stuff under FProcess

Thanks for your response.

Can I get from process that the process is completed and now I can continue with my task even if process is not killed.

Many thanks once again

You can also do it with an event.

FProcess.EnableRaisingEvents=true;

And then

private void FProcess_Exited(object sender, System.EventArgs e)
    {
   
    }

Make sure that you have a delegate event handler set up

e.g.
in a form
      this.FProcess.SynchronizingObject = this;
      this.FProcess.Exited += new System.EventHandler(this.FProcess_Exited);

Hi,

I want to do something like this

  if(FProcess.WaitForExit())
            {
                MessageBox.Show("Exited");
            }//waits till it exists
            if(FProcess.HasExited())
            {
                MessageBox.Show("has exited");
            }

How to do this and also, this is error.

Can I get from process that the process is completed and now I can continue with my task even if process is not killed.

Many Thanks

s as nightnman said that would be an option if u dont want to raise events but handle this separately in another thread then u could start a thread after u start the process and and in the function which is called by the thread have an infinite loop like



while (!FProcess.HasExcited)
{

}
 Application.Exit()


but this is necessary if u want to handle ur new process in a new thread ...if u dont want this to be a new process u coudl raise the even as
