Hello all,

This is my first post and I am counting on the experience of all of you to get some help :)

I am working on a C# project and my program has to start different other applications, one by one. When an application finishes it's execution, I want to popup a message box and some other things that are not important. The applications are called from within a thread with a process, and I use an EventHandler to be called after the process finishes, just like some sort of callback function.

This works if the application I call does not call itself other applications. If so, the EventHandler that is called after the thread exits is called prematurely. More precise, I have this problem with an installer that is built with InstallShield. After the progress bar that initializes that installation, the "doneThread" EventHandler is called.

I want "doneThread" to be called when the installation finishes, not after the progress bar and installation initialization is complete.

I hope I make myself clear.. Can anyone help me on this topic?

private string commandName;
private void Begin()
        {
            StartProcess("C:\dummy_app.exe");
        }
....

public bool StartProcess(string FileName)
        {
            try
            {
               commandName = FileName;

                myThread = new Thread(this.threadWork);
                myThread.Start();

                return true;
            }
            catch (Exception)
            {
                MessageBox.Show("BlaBla");
                return false;
            }
        }

private void threadWork()
        {
            EventHandler eh = new EventHandler(doneThread);

            try
            {   
                Process p = Process.Start(commandName);
                p.WaitForExit();
            }
            catch (Exception)
            {
                MessageBox.Show();
            }

            try
            {
                //invoke doneThread when installer exits
                // this is where I do my post-exit things
                this.Invoke(eh);
            }
            catch (Exception)
            {
            }
        }

private void doneThread(object sender, EventArgs e)
        {
           ...
           // unimportant
        }

Thanks a lot for reading it all to this point :)

You can set the EnableRaisingEvents property on the Process
instance to true, and then subscribe to the Exited event.
