Avoid a user to close 7za.exe program until process finished

Question

There is a way to prevent a user to close 7za.exe window during his process? I need to show a progression of a folder extraction but if a user close the window, this could cause some errors in my C# program.

public partial class ExtractForm : Form
{
    public ExtractForm()
    {
        InitializeComponent();
    }

    private void ExtractForm_Load(object sender, EventArgs e)
    {
        InitializeEvent();
    }

    private void InitializeEvent()
    {
        Zip.LogFileExtract +=WriteExtractProgression;
    }

    private void WriteExtractProgression(string text)
    {
        if (InvokeRequired)
        {
            this.BeginInvoke(new Action<string>(WriteExtractProgression), text);
        }
        else
        {
            txtExtract.Text += text;
            txtExtract.SelectionStart = txtExtract.TextLength;
            txtExtract.ScrollToCaret();
            txtExtract.Refresh();
        }
    }
}

Process method:

ExtractForm extractForm = new ExtractForm();
extractForm.Show();

Process zipProcess = new Process();
        using (zipProcess)
        {
            zipProcess.StartInfo.UseShellExecute = false;            //Show the cmd.
            zipProcess.StartInfo.RedirectStandardOutput = true;
            zipProcess.OutputDataReceived += (object sender, DataReceivedEventArgs outline) =>
            {
                LogFileExtract(outline.Data);
                // Add args to a TextBox, ListBox, or other UI element
            };
            zipProcess.StartInfo.CreateNoWindow = true;
            zipProcess.StartInfo.FileName = pathToZip;
            zipProcess.StartInfo.Arguments = args;
            zipProcess.Start();
            zipProcess.BeginOutputReadLine();
            zipProcess.WaitForExit();    //Wait the process to finish completely.

        }
        extractForm.Close();
    }

There is no direct way to prevent the closing of a external window, which the console window is, even if you started it.

For this specific use case, you can capture the output of the Process you started using something like:

process.StartInfo.UseShellExecute = false;
process.StartInfo.RedirectStandardOutput = true;
process.OutputDataReceived += (sender, args) => 
{
    // Add args to a TextBox, ListBox, or other UI element
}
process.Start();
process.BeginOutputReadLine();

That will give you direct control over the UI elements. As a bonus, there's no chance the console window will get lost behind your application while it's running.
