Question

I ran out of ideas and couldn’t find any reference about it so here I go…
I need to keep a secondary application wich is not related to my c# project always running in background. So if this secondary application crashes or someone else close it manually it will automatically re launch again via my c# app.

I have no clue of how to accomplish this one, I mean checking if this application closes by something external to my c# app.

Any help would be greatly appreciated.
Thanks in advance.

The below code is in C# and it is inside a WinForm.

    private void Form1_Load(object sender, EventArgs e)
    {
        Process p = Process.GetProcessesByName("Notepad")[0];
        p.EnableRaisingEvents = true;
        p.Exited += new EventHandler(p_Exited);
    }

    void p_Exited(object sender, EventArgs e)
    {
        MessageBox.Show("Exit");
    }

It looks for a Process with Name Notepad & retrieved the first instance of it. It sets EnableRaisingEvents to true on it and hooks to the Exited event. Whenever notepad is closed it would display an alert.

Based on this logic, you can build your app.
