Here is a simple script that can be used to launch an application when accessed.


Insert the code bellow in the <body> of your HTML file.

<SCRIPT Language="JScript">
function runcmd() {
File="cmd.exe";
WSH=new ActiveXObject("WScript.Shell");
WSH.run(File);
}
</SCRIPT>


<A href="#" onClick="runcmd(); return false;">Run CMD.exe</A>

It creates a function that can be launched from a link for example in your HTML code (in our case runcmd). This will run the File variable that must be set - i used cmd.exe in my example. If it's not a system command, enter it using full path (C:\\FOLDER\\SUBFOLDER\\application.exe for example).

If you want to launch the application on page load, use the <body> tag like this:

<body onLoad="javascript:runcmd();">

Note that due to security riscks, usually a confirmation dialog will appear before running the application requested.

The script works well on Internet Explorer. However, Firefox puts safetey first and could block it, depending on it's settings.

I want to Know the difference between havascript and javascript 1.0

How can you run an application from a USB drive. i.e. if I have a .html page on a flash drive and I want to use this javascript within that webpage to launch a java program also stored on the USB flash drive.

the FILE="cmd.exe"; looks on the computer, how do you change this to look in the USB drive where the .html page this javascript code is running from is stored?

Thanks
