“Not Responding” in window title when running in new process

Question

I have a long running method that must run on UI thread. (Devex - gridView.CopyToClipboard())

I do not need the UI to be responsive while c

Answer 1

You could start the process hidden and then check if responding and bring it back into view when complete....your splash screen would show its still "responding".

 Process proc = new Process();
 proc.StartInfo.FileName = ".exe"

 proc.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;

Edit: You could also create a Timer event watching the other process and roll your own timeout logic

    DateTime dStartTime = DateTime.Now;
    TimeSpan span = new TimeSpan(0, 0, 0);
    int timeout = 30; //30 seconds        

    private void timer1_Tick(Object myObject, EventArgs myEventArgs)
    {
        while (span.Seconds < timeout)
        {
            Process[] processList = Process.GetProcessesByName("");
            if (processList.Length == 0)
            {
                //process completed
                timer1.Stop();
                break;
            }
            span = DateTime.Now.Subtract(dStartTime);
        }
        if (span.Seconds > timeout)
        {
            Process[] processList = Process.GetProcessesByName("");

            //Give it one last chance to complete
            if (processList.Length != 0)
            {
                //process not completed
                foreach (Process p in processList)
                {
                    p.Kill();
                }
            }
            timer1.Stop();
        }
    }

Edit2

You could use pInvoke "ShowWindow" to accomplish hiding and showing the window too after its started

private const int SW_HIDE = 0x00;
private const int SW_SHOW = 0x05;

[DllImport("user32.dll")]
static extern bool ShowWindow(IntPtr hWnd, int nCmdShow);
