title: how to control mouse movement in visual c++?
body: <p>I am doing a project where a regular monitor could be converted into a touchscreen.
  For this purpose i have designed a grid of ir sensors and installed them into a frame that could be put around the screen. That concludes the hardware.</p>
  
  <p>What i want to do is control the mouse movement using the grid, so that when the user moves his/her finger inside the frame it moves the mouse on the screen. Thus giving the effect of a touchscreen. I hope I am clear in explaining my problem. I am using Windows,MS Visual C++.</p>
  
  <p>If there is any suggestion other than visual C++, please let me know.
  Thank you.</p>
