I am trying to run shell command to open notepad from JavaScript. This is how my code looks like:
<script type="text/javascript">
function runNotepad() {
var oShell = new ActiveXObject("Shell.Application");
var commandtoRun = "C:\\WINDOWS\\Notepad.exe";
oShell.ShellExecute(commandtoRun, null, "", "open", "1");
}
</script>
When i try to run this, it throws me an error saying Microsoft JScript runtime error: Permission denied.
I also have set Allow active content to run in files on my computer in IE but still no luck.
Any idea what am i missing here?

No browser would allow JavaScript to arbitrarily start a process. This functionality is not available in Internet Explorer because of the security implications.
This will work if run from other Scripting Hosts, such as cscript, but not Internet Explorer.
You can't run or create native objects inside webpage javascript. The idea is that if someone could do that, then they could create a FileSystem object. Then, while you idly browse their webpage, they play havoc with your file system.
If you need to do this, and have the file saved on the host's machine, save it as an HTML app (*.hta).

I hava a java program with two buttons, one for chrome and one for firefox. I press one of them, and the browser starts at some particualar location on the screen and with smalles size.
i have try running terminal commands, something like this
"C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --profile-directory="Default" --app="data:text/html,<html><body><script>window.moveTo(198,60);window.resizeTo(1167,708);window.location='https://stackoverflow.com';</script></body></html>"
And it works, but only for chrome. I want at least chrome and firefox on both windows and linux.
Searching a little I have come across other solution. Running javascript on java, somethig like:
ScriptEngineManager factory = new ScriptEngineManager();
ScriptEngine engine = factory.getEngineByName("JavaScript");
engine.eval("window.open('https://stackoverflow.com')");
engine.eval("window.resizeTo(800,600)");
But Im getting compilation errors:
ReferenceError: "window" is not defined in <eval> at line number 1
And I don´t know whats going. Ideas?
For Windows, you can do something like this using Runtime:
Runtime rt = Runtime.getRuntime();
rt.exec("C:\\Program Files (x86)\\Mozilla Firefox\\firefox.exe stackoverflow.com");
I believe that you can do something similar for Google Chrome. I took a look to a code I implemented in the past for Chrome and it was a little different, but previous approach should work as well:
Runtime rt = Runtime.getRuntime();
rt.exec(new String[]{"cmd", "/c","start chrome http://www.stackoverflow.com"});
If you would like to do it for a Linux based OS, then you can use Runtime as well:
Runtime rt = Runtime.getRuntime();
rt("/usr/bin/firefox -new-window http://www.stackoverflow.com");
I remember I got some references from this page:

Hope it can help you.
ScriptEngineManager runs the script on server side. window is a client-side object, you can't access it from server.
in another word since you are not executing your script in a browser, the window object is not defined.
You can try this way to open a website on your default browser of the operating system:
Desktop desktop=Desktop.getDesktop();
URI url = new URI("http://somewhere");
desktop.browse(url);
to open a non-default browser in Java you should use Runtime.exec()
for Windows OS try this it worked for me:
String browserPath = "C:/Program Files/Mozilla Firefox/firefox.exe";
String url = "http://somewhere";
try {
String[] b = {browserPath, url};
Runtime.getRuntime().exec(b);
}
catch (Exception exc) {
exc.printStackTrace();
}
for further information on how to use Runtime.exec() on others OS read here
I have following javascript code to run notepade.exe:
<SCRIPT type="text/javascript" LANGUAGE="JavaScript">
function executeCommands()
{
var oShell = new ActiveXObject("Shell.Application");
var commandtoRun ="C:\WINDOWS\notepad.exe";
oShell.ShellExecute(commandtoRun,"","", "open", "1");
}
</SCRIPT>
The problem is that, when i run the script then it give error..."Permission denied."
Can anybody help me on this matter?
It's necessary to have two settings turned on.
Enable unsigned ActiveX controls for the current zone
Tools > Internet Options > Security > Custom level...
Enable "ActiveX Controls and plug-ins" > "Initialize and script ActiveX controls not marked as safe for scripting"
Allow Active Content to run files
Tools > Internet Options > Advanced > Security
Enable "Allow Active Content to run in files on My Computer"
** Make sure to close all your IE browser windows.
You may experience a "Permission denied" error, which means that the browser will not let script execute outside the "sandbox". Try solving the issue by changing a security setting in the browser:
Internet Options, Advanced, Security:
"Allow Active Content to run in files on My Computer"
The above is for IE, but most browsers have similar options.
Okay, weirdly, I had this issue when running a .html file I'd created on my desktop into IE... but when I moved the file onto a WAMPServer it worked okay; Not quite sure why that should solve the problem, but maybe that'll help someone!?
I have a situtaion where i need the command prompt to open on the click of a button. for this i started of by usign jsp.
var wsh = new ActiveXObject('WScript.Shell');
command = "cmd /k D:\ & cd testTrial & trial.bat & echo DONE!"
wsh.Run(command);
The problem is that this wont run in firefox as ActiveXObject is a Microsoft propritory.
Is there a way i can check the browser and then run the above code keeping the current browser in mind.
This sounds like a security hole... I don't think you will be able to do that.
As I know for security reason other browsers does not allow to access local resources.
I m trying to open Notepad, Calculator in button click in asp.net with code behind C#. I tried with the code
System.Diagnostics.Process.Start("c:\\windows\\system32\\notepad.exe");
this is working fine in local system but not working in the Server. I even tried with the javascript
function executeCommands(inputparms)
{
alert('ff');
var oShell = new ActiveXObject("Shell.Application");
var commandtoRun = "C:\\Winnt\\Notepad.exe";
if (inputparms != "")
{
var commandParms = document.form1.filename.value;
}
oShell.ShellExecute(commandtoRun, commandParms, "", "open", "1");
}
even this is not working out. Can you please suggest me in on how to open the notepad application in the client end with out disturbing server notepad.
This can't be done. Imagine the security mess we'd be in if a web-page could run arbitrary programs on a client machine. Oh wait... ;-)
This is not possible (in general, though you could possibly get around with with various applets and browser plugins). In fact, I would be quite mortified if any web page could execute an arbitrary program on my computer.
You cannot do this. ASP.NET runs on the server and you cannot run programs on the client computer. The ActiveX object you have shown should work but only in IE and only after the user explicitly authorizes the execution of it. Also the location of notepad.exe might differ depending on the client (could be c:\windows, c:\winnt, ... and some clients running for example on Linux or MacOS don't have such executable)
What you are trying to achieve is not possible because of the nature of application in case of ASP.Net. The application will execute on server and will only send client side HTML to client. Even if your code is syntatically correct, it would open up the utilities on server itself.
This Can be possible by using below code on click of server button or Link.
System.Diagnostics.Process.Start("notepad.exe");
System.Diagnostics.Process.Start("C:\Windows\System32\calc.exe")
Works fine, though you may have to adjust settings on your browser. Be sure calc.exe is in the directory.
I wrote a javascript function in my html page to execute an .exe file. for this i used ActiveXObject.
my function is:
//~~~~~~~~~~~~~~~~~~~~~~~~~~~JavaScript~~~~~~~~~~~~~~~~
function openWin(url)
{
if (!document.all) {
alert ("Available only with Internet Explorer.");
return;
}
var ws = new ActiveXObject("WScript.Shell");
ws.Exec(url);
}
//~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
It works fine but there is a alert "An ActiveX control might be unsafe to interact with other parts of the page. Do you want to allow this interaction?" comes up to confirm. If i say YES only it will get loaded.
Pls anyone help me on this how to avoid this pop-up coming every time when i reload my html page.
You can't. Your users can, by giving your page trusted access to their computer (e.g., by adding the URL to the "Trusted Sites" zone).
You should enable activeX in Internet explorer security settings.

If you want your users to not seeing this message, then they should enable it. But you can't force them to do it because of security issues.
