WScript.Shell without dos screen

Exec always shows the console window.



But if you don't need to access StdIn/StdOut/StdErr streams, you can use Run. It hides the console window if you set the 2nd parameter to 0:

var WScriptObj = Sys.OleObject("WScript.Shell");



// Run the command and wait for completion

WScriptObj.Run("...", 0, true);



// Run the command but don't wait for completion

WScriptObj.Run("...", 0, false);

Hi Chris,



As Helen wrote, setting third parameter to True delays script execution until the called command completes :

What is not possible?

You can check the return (exit) code, but there is no need in timeout as by design the method waits until the called command completes.

If you need a timeout, you may call .Run asynchroniously (using its third parameter) and then check in a loop if the command completed and terminate the started process if timeout expired.



BTW, may I wonder why it is so critical that DOS window must be not visible in the test?

Ok.



But i would like to wait the end of command also?

How configure the timeout?

How test the return status?

So, it is not possible with "WScriptObj.Run".

An example to test the return?
