title: opening excel file via c# application
body: <p>My application using excel file in order to read data from web (using excel web query and reading the data from the excel file)<br>
  The excel file I'm using called webGate.<br>
  my problem is that I don't want webGate to be presented to the user.<br>
  if the user opens excel file (any other file) while my application is reading the webGate file the webGate file is presented with the user file<br>
  (i.e. user opens excel file and two files are being presented one of them is the webGate)<br>
  Any idea about how can I use the file but it will never be presented to the user?<br>
  Thanks<br>
