title: How to access the previous form after doing showdialog?
body: <p>Having trouble figuring this one out..</p>
  
  <p>I currently have a frmMain and a frmLoading..</p>
  
  <p>inside frmMain Shown event, I'm doing </p>
  
  <pre>frmLoading load = new frmLoading();
  load.ShowDialog();</pre>
  
  <p>inside frmLoading.. I want to access frmMain..
  I know I could pass the previous form inside constructor
  but I'd like to avoid that if possible..</p>
  
  <p>Was thinking it would be this.Owner, or this.Parent.. nope, searched through all the properties in "this", "Form".. could not find it..</p>
  
  <p>Any idea?</p>
