title: How to connect two different windows forms keeping both open
body: <p>I have developed a desktop application containing two forms. The 2ND form opens on click of first form. Now after opening second form I want to move both forms simultaneously on desktop.
  and also the location of form should be changed. Means if second form opens on left side and i move both forms to left of screen after reaching extreme left border the second form should open at right side of first form and vice versa.
  now I can open the second form on left or right of first form depending on its location.(If first form is at left side the second will open at its right side and vice versa)
  How to do this? 
  Thanks in advance..!!</p>
