title: web browser set javascript variable value
body: <p>Is there a way for me to get and set the values of JavaScript variables in a win form web browser so it can communicate with my application.
  The only way I can think of accomplishing this is by using a proxy of an invisible element such as a div that will have an attribute or inner HTML set to the value I want to read/write. </p>
  
  <p>Also, is there a JavaScript function that gets me the cursor's current position.
  Not event based callsbacks that have the position in its parameters. This is for a complicated application.</p>
