Run external Application from Expert Advisor

 
I don't see how it's possible to run an external application from an expert advisor. Is this correct? This is something I think should be included if it isn't.
 
You need to write your own dll for your purposes
import from dlls works ok. see our samples
if You do not need for waiting results from exe then You may assign your exe-file to alert event (Tolls-Options-Events tab). Alert function call from expert advisor launches assigned exe-file
 
Thanks.. The alert exe assignment should work fine :-)
 
Is there any way to run 2 applications? I need to run one if the indicator tells me buy, and a different one if it tells me sell. Can I use a different alert to set this up? I have the one Alert set to buy, I also see an expert advisor sound. How would I code it so I could utilize that to run a different application?
