I built a gadget that shows an on-call rotation for a team, and I am trying to integrate their communicator presence into that shedule. I am using the GetStatus method from the NameCtrl object to get user presence. It works fine in IE when I run it. The problem I am having is that the gadget has a runtime error whenever it hits the ActiveX object declaration. I know this because I commented it out and it runs fine. Any suggestions?
var communicatorPresence = getCommunicatorPresence(userName);
function getCommunicatorPresence(userName){
var obj = new ActiveXObject("Name.NameCtrl.1")
var presence = obj.GetStatus(userName,"")
return presence;
}
I debugged the gadget in Visual Studio and put a breakpoint there, and the error was "Automation Server can't create object"
Depending on the machines UAC settings it might be that gadget does not have read/write access the registry.

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:
https://www.mkyong.com/java/open-browser-in-java-windows-or-linux/
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 a very simple javascript code in oracle procedure which us used for fetching the Username for Active Directory as my application don't have any user interface.
htp.p('function disp_alert()');
htp.p('{');
htp.p('var WinNetwork = new ActiveXObject("WScript.Network")');
htp.p(' WinNetwork = WinNetwork.UserName');
htp.p('alert(WinNetwork)');
htp.p('}');
It throws exception ActiveXObject creation error: Automation server can't create object
I tried changing browser setting script ActiveX controls marked safe for scripting to enable and it worked.
But in my case the application is accessed by users in client network and we can't tweak security settings for each machine in network. Can anyone suggest an alternative solution or any other method for fetching the windows username?
If you absolutely have to use WScript.Shell for whatever you want to accomplish, you may set the option for your intranet zone by GPO.
You may find the corresponding GPO setting with the help of that site: https://getadmx.com/?Category=InternetExplorer&Policy=Microsoft.Policies.InternetExplorer::IZ_PolicyScriptActiveXMarkedSafe_3
How do i set up a custom protocol handler in chrome? Something like:
myprotocol://testfile
I would need this to send a request to http://example.com?query=testfile, then send the httpresponse to my extension.
The following method registers an application to a URI Scheme. So, you can use mycustproto: in your HTML code to trigger a local application. It works on a Google Chrome Version 51.0.2704.79 m (64-bit).
I mainly used this method for printing document silently without the print dialog popping up. The result is pretty good and is a seamless solution to integrate the external application with the browser.
HTML code (simple):
Click Me
HTML code (alternative):
<input id="DealerName" />
<button id="PrintBtn"></button>
$('#PrintBtn').on('click', function(event){
event.preventDefault();
window.location.href = 'mycustproto:dealer ' + $('#DealerName').val();
});
URI Scheme will look like this:
You can create the URI Scheme manually in registry, or run the "mycustproto.reg" file (see below).
HKEY_CURRENT_USER\Software\Classes
mycustproto
(Default) = "URL:MyCustProto Protocol"
URL Protocol = ""
DefaultIcon
(Default) = "myprogram.exe,1"
shell
open
command
(Default) = "C:\Program Files\MyProgram\myprogram.exe" "%1"
mycustproto.reg example:
Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\Software\Classes\mycustproto]
"URL Protocol"="\"\""
#="\"URL:MyCustProto Protocol\""
[HKEY_CURRENT_USER\Software\Classes\mycustproto\DefaultIcon]
#="\"mycustproto.exe,1\""
[HKEY_CURRENT_USER\Software\Classes\mycustproto\shell]
[HKEY_CURRENT_USER\Software\Classes\mycustproto\shell\open]
[HKEY_CURRENT_USER\Software\Classes\mycustproto\shell\open\command]
#="\"C:\\Program Files\\MyProgram\\myprogram.exe\" \"%1\""
C# console application - myprogram.exe:
using System;
using System.Collections.Generic;
using System.Text;
namespace myprogram
{
class Program
{
static string ProcessInput(string s)
{
// TODO Verify and validate the input
// string as appropriate for your application.
return s;
}
static void Main(string[] args)
{
Console.WriteLine("Raw command-line: \n\t" + Environment.CommandLine);
Console.WriteLine("\n\nArguments:\n");
foreach (string s in args)
{
Console.WriteLine("\t" + ProcessInput(s));
}
Console.WriteLine("\nPress any key to continue...");
Console.ReadKey();
}
}
}
Try to run the program first to make sure the program has been placed in the correct path:
cmd> "C:\Program Files\MyProgram\myprogram.exe" "mycustproto:Hello World"
Click the link on your HTML page:
You will see a warning window popup for the first time.
To reset the external protocol handler setting in Chrome:
If you have ever accepted the custom protocol in Chrome and would like to reset the setting, do this (currently, there is no UI in Chrome to change the setting):
Edit "Local State" this file under this path:
C:\Users\Username\AppData\Local\Google\Chrome\User Data\
or Simply go to:
%USERPROFILE%\AppData\Local\Google\Chrome\User Data\
Then, search for this string: protocol_handler
You will see the custom protocol from there.
Note: Please close your Google Chrome before editing the file. Otherwise, the change you have made will be overwritten by Chrome.
Reference:
https://msdn.microsoft.com/en-us/library/aa767914(v=vs.85).aspx
Chrome 13 now supports the navigator.registerProtocolHandler API. For example,
navigator.registerProtocolHandler(
'web+custom', 'http://example.com/rph?q=%s', 'My App');
Note that your protocol name has to start with web+, with a few exceptions for common ones (like mailto, etc). For more details, see: http://updates.html5rocks.com/2011/06/Registering-a-custom-protocol-handler
This question is old now, but there's been a recent update to Chrome (at least where packaged apps are concerned)...
http://developer.chrome.com/apps/manifest/url_handlers
and
https://github.com/GoogleChrome/chrome-extensions-samples/blob/e716678b67fd30a5876a552b9665e9f847d6d84b/apps/samples/url-handler/README.md
It allows you to register a handler for a URL (as long as you own it). Sadly no myprotocol:// but at least you can do http://myprotocol.mysite.com and can create a webpage there that points people to the app in the app store.
This is how I did it. Your app would need to install a few reg keys on installation, then in any browser you can just link to foo:\anythingHere.txt and it will open your app and pass it that value.
This is not my code, just something I found on the web when searching the same question. Just change all "foo" in the text below to the protocol name you want and change the path to your exe as well.
(put this in to a text file as save as foo.reg on your desktop, then double click it to install the keys)
-----Below this line goes into the .reg file (NOT including this line)------
REGEDIT4
[HKEY_CLASSES_ROOT\foo]
#="URL:foo Protocol"
"URL Protocol"=""
[HKEY_CLASSES_ROOT\foo\shell]
[HKEY_CLASSES_ROOT\foo\shell\open]
[HKEY_CLASSES_ROOT\foo\shell\open\command]
#="\"C:\\Program Files (x86)\\Notepad++\\notepad++.exe\" \"%1\""
Not sure whether this is the right place for my answer, but as I found very few helpful threads and this was one of them, I am posting my solution here.
Problem: I wanted Linux Mint 19.2 Cinnamon to open Evolution when clicking on mailto links in Chromium. Gmail was registered as default handler in chrome://settings/handlers and I could not choose any other handler.
Solution:
Use the xdg-settings in the console
xdg-settings set default-url-scheme-handler mailto org.gnome.Evolution.desktop
Solution was found here https://alt.os.linux.ubuntu.narkive.com/U3Gy7inF/kubuntu-mailto-links-in-chrome-doesn-t-open-evolution and adapted for my case.
I've found the solution by Jun Hsieh and MuffinMan generally works when it comes to clicking links on pages in Chrome or pasting into the URL bar, but it doesn't seem to work in a specific case of passing the string on the command line.
For example, both of the following commands open a blank Chrome window which then does nothing.
"c:\Program Files (x86)\Google\Chrome\Application\chrome.exe" "foo://C:/test.txt"
"c:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --new-window "foo://C:/test.txt"
For comparison, feeding Chrome an http or https URL with either of these commands causes the web page to be opened.
This became apparent because one of our customers reported that clicking links for our product from a PDF being displayed within Adobe Reader fails to invoke our product when Chrome is the default browser. (It works fine with MSIE and Firefox as default, but not when either Chrome or Edge are default.)
I'm guessing that instead of just telling Windows to invoke the URL and letting Windows figure things out, the Adobe product is finding the default browser, which is Chrome in this case, and then passing the URL on the command line.
I'd be interested if anyone knows of Chrome security or other settings which might be relevant here so that Chrome will fully handle a protocol handler, even if it's provided via the command line. I've been looking but so far haven't found anything.
I've been testing this against Chrome 88.0.4324.182.
open
C:\Users\<Username>\AppData\Local\Google\Chrome\User Data\Default
open Preferences then search for excluded_schemes you will find it in 'protocol_handler' delete this excluded scheme(s) to reset chrome to open url with default application
I ran into a nasty problem with Lawnchair (0.6.1). I want to have 2 globally accessible collections/Lawnchairs, both with the webkit-sqlite adapter. This is how I declare them, right after loading Lawnchair and the adapter:
var clientStore = Lawnchair({name: 'clients'}, function () {});
var companyStore = Lawnchair({name: 'companies'}, function () {});
// other global variables
...
In Safari and Chrome on my desktop everything is smooth sailing, same for my iPad and other iOS devices in the emulator using Phonegap (3.0.0). No problems at all, both databases show up in the web inspector and in Weinre. I can use them in any of JQuery Mobile events (version 1.3.2 and 1.4.0 beta). Manually checking the database objects in Weinre confirms that they are indeed using the webkit-sqlite adapter.
But if run the Phonegap app on Android, only the clientStore is accessible and usable. Trying to access the companyStore gives me the following error:
companyStore.all(function (allEntries) {
console.log(allEntries);
...
> TypeError: Cannot call method 'all' of undefined
The only database that shows up in Weinre on the Android device is the clients database. Manually initializing the companies database from the Weinre inspector console after everything loaded up doesn't show any effect on the list of databases on the 'Resources' tab or change anything else (except for the above error visually disappearing).
Trying to access the 'undefined' companyStore programmatically, say when someone switches to a page where all the companies shall be listed, 'crashes' the UI on the Android device. Nothing even gets printed on the console anymore after that. As said, all other platforms work just fine.
Am I just doing something stupidly wrong or did I encounter a bug/feature?
Thanks a ton for the help, this one is driving me up the wall :(.
Edit: using the standard DOM adapter works for me on every platform so far. I guess I'll stick to that one for now. In case someone ran into the same problem, here's how to explicitly use the DOM adapter:
var clientStore = Lawnchair({name: 'clients', adapter: 'dom'}, function () {});
var companyStore = Lawnchair({name: 'companies', adapter: 'dom'}, function () {});
I have a native (windows) application that has an embedded web browser. Currently I'm invoking a javascript function from the backend (c++/c#). However, if javascript is disabled this fails and I'd like to provide a fallback mechanism. Is there a way to determine if javascript is disabled?
In the IE Web Control, you can simply force JavaScript on. Please refer to the following interfaces, which your host has to implement:
IDocHostUIHandler
IDocHostShowUI
IInternetSecurityManager
IServiceProvider
Another approach would be for your HTML page to query the window.external object and call a method on it, which you implement in your host, which sets a flag to true. Not being called would mean the JavaScript was not executed.
Wow, using web browser under mfc is really pain in the ass, you can do it by getting the IInternetSecurityManager, and check if is enabled to execute javascript by current policy, if user select to disable javascript on his IE, you will need to overwrite the value in the registry.
HRESULT hr = CoCreateInstance(CLSID_InternetSecurityManager, NULL,
CLSCTX_INPROC_SERVER,IID_IInternetSecurityManager, (void**)&pSecurityMgr);
int policy = URLPOLICY_ALLOW;
hr = pSecurityMgr->ProcessUrlAction(L"http://www.google.com", URLACTION_SCRIPT_RUN,
(BYTE*)&policy, sizeof(policy), NULL, 0, PUAF_TRUSTED, 0);
if hr = S_FALSE, javascript execution is disabled...
