title: How to post/trigger events to invisible controls in PowerBuilder?
body: <p>I have a scenario where some windows are required to be automated non-visually from a controller window, that opens, sets parameters and send events to the other windows controls, like SetFocus (mostly text boxes) and Clicked (exclusively to buttons).</p>
  
  <p>The process works fine when the controlled windows are visible, but it doesn't work when they are invisible.</p>
  
  <p>It's a MDI application.</p>
  
  <p>I tried to set the Width and Height of controlled windows to 0, but the title bar still shows up. The controller window can't be application modal (Response kind).</p>
  
  <p>Some ideas on how to do that?</p>
  
  <p>Thanks in advance.</p>
