Sending data to a notepad using processes

Question

I want to send every item from my listbox to a notepad,but my logic is kinda beating me.

private void send_Click(object sender, EventArgs e)
{
    var notepad =          


        

Answer 1

From @GillBates suggestion I used System.Threading.Thread.Sleep(); and it seem to work great now.

private void send_Click(object sender, EventArgs e)
{
 var notepad = Process.GetProcessesByName("Notepad").FirstOrDefault(p => p.MainWindowTitle == "Untitled - Notepad");

            if (notepad != null)
            {
                if (IsIconic(notepad.MainWindowHandle))
                    ShowWindow(notepad.MainWindowHandle, 9);

                SetForegroundWindow(notepad.MainWindowHandle);
                string text = "";

                foreach (var item in listBox1.Items)
                {
                    text = item.ToString();
                    Clipboard.SetText(text);
                    SendKeys.Send("^V");
                    SendKeys.Send("{ENTER}");
                    System.Threading.Thread.Sleep(150);
                }

            }
}
