Open With

I am saving a txt file and I want it to open (execute) in excel after the script creates it.

I probably can't do it in JS and need to do a little doScript in VB and AS

Can anyone show me how to do this.

Something like

function openWith (myFile, myProgram)      {             if ($.os.match(/Mac/i)) app.doScript ("appleOpenWith (" + myFile + ", " +  myProgram + ")", ScriptLanguage.APPLESCRIPT_LANGUAGE);             else app.doScript ("windowsOpenWith (" + myFile + ", " +  myProgram + ")", ScriptLanguage.VISUALBASIC);    }  
function appleOpenWith (myFile, myProgram)     {          \\ SOME APPLE SCRIPT HERE. WHAT????     } 
function windowsOpenWith(myFile, myProgram)     {          \\ SOME VB HERE. WHAT????     }

Thanks
