title: Close popup from c#
body: <p>I have an exe program called &quot;workcall.exe&quot; which I don't have access to the source code.
  workcall.exe occasionally throws a popup.</p>
  <p>I want to write a c# program to close the popup from &quot;workcall.exe&quot; if it occurs. How can I identify the popup of this &quot;workcall.exe&quot;?</p>
