Run exe with javascript and get response

Question

Here is my code for running exe using javascript. It's working fine. Is there a way for me to know:

1. When the exe closed.
2. Get a return value from this app.

Also, what is the difference between using ShellExecute & Run?

     var sExePath = "c:\\Debug\\WebToCardReader_Test.exe";
     var oShell = new ActiveXObject("Shell.Application");
     var oExec = oShell.ShellExecute(sExePath, "", "", "open", "1");

Answer 1

1. Run allows you to set the boolean bWaitOnReturn flag, which blocks your script until the program returns.

2. On that page, the VBScript sample simply assigns the command to a variable (as you've done with ShellExecute). I'm not sure if this works in JavaScript, but it's worth a shot.

   However, as you know, ShellExecute does allow you to store a return value.
