title: Update textbox contained within a different form
body: <p>I have 2 forms. The second form is opened from a method in the first form and I wish to be able to update the textbox that exists within that second form.</p>
  
  <p>Basically I have the following code:</p>
  
  <pre><code>    private void sendAllButton_Click(object sender, EventArgs e)
      {
          SendConsoleGUI sendOutGUI = new SendConsoleGUI();
          sendOutGUI.Show();
          sendOutGUI.sendConsoleTextBox.Text = "Test";       
      }
  </code></pre>
  
  <p>When I press the button the second form (SendConsoleGUI form) opens but "Test" is never added to its textbox.</p>
  
  <p>Am I doing something wrong here?</p>
