title: Fooling an app about mouse location
body: <p>First of all if there is any language-specific solutions to this that are only possible in c++/c#/java etc. please say so because im fine with using any one.
  Currently I'm trying to click a button in an app that is at background, and I can manage the "click" part using send/post message. Like so:</p>
  
  <pre><code>            SendMessage(Window, 0x201, 0, 700 * 0x10000 + 700);
  </code></pre>
  
  <p>0x201 here is left mouse button down and supposedly location should be 700, 700</p>
  
  <p><strong>However, when I send that message the app im trying to fool acts based on my current mouse position and not 700,700.</strong></p>
  
  <p>I believe this is due to the fact that the app im trying to fool looks for current mouse position. any way to fool that ? </p>
