title: Setting focus to a textbox control
body: <p>If I want to set the focus on a textbox when the form is first opened, then at design time, I can set it's tabOrder property to 0 and make sure no other form control has a tabOrder of 0.</p>
  
  <p>If I want to achieve the same result at run-time, using code, how should I proceed?<br>
  Are there alternatives to using tabOrder?<br>
  I assume any run-time code will be in the form's constructor or its onload event handler?</p>
  
  <hr>
  
  <p><strong>EDIT</strong><br>
  In other words I'd like to be able to type straight into the textbox as soon as the form appears without having to manually tab to it, or manually select it.</p>
