title: CreateFileMapping - Shared Memory Applications
body: <p>this is my first question here. I hope dont make any mistake, be good with me...</p>
  
  <p>I am very confused with shared files..
  I have two applications and I want to exchange data between them. 
  I tried with CreatefileMapping functions but now I need an event that warn me when the shared file have new data from the other application (is it possible?)</p>
  
  <p>I dont know if it will possible with a filesystemwatcher because i dont have a file path...</p>
  
  <p>Do you recommend working with Messaging instead??</p>
  
  <p>thanks a lot.</p>
