I am developing extension for Firefox 3.0-3.5 versions using VS2008.
I want to set attribute to a tab once the document load request completes within that tab window.
So in OnStateChange method, I am checking for document load.
I have used STATE_STOP & STATE_IS_DOCUMENT for it.
I want to determine which tab window has been associated with particular document request.
I have valid DOM Document pointer got from nsIWebProgress *aWebProgress which is 1st input
parameter of OnStateChange.
if ((aStateFlags & STATE_STOP) && (aStateFlags & STATE_IS_DOCUMENT))
{
nsCOMPtr<nsIDOMWindow> domwin;
nsCOMPtr<nsIDOMDocument> domDoc;
aWebProgress->GetDOMWindow(getter_AddRefs(domwin));
domwin->GetDocument(getter_AddRefs(domDoc));
}
I have tried to get nsIDOMDocumentXBL pointer by QIing nsIDOMDocument pointer(domDoc in my example) but it fails with Error code 0x80004002 (2147500034) i.e.NS_ERROR_NO_INTERFACE.
How do I get the tab element corresponding to document load request.
Could any one please help me?
Thanks in Advance,
Vaibhav D. Gade.
IF I understood the question correctly and you want a for a content window, you probably need https://developer.mozilla.org/en/Working_with_windows_in_chrome_code#Accessing_the_elements_of_the_top-level_document_from_a_child_window to get the chrome window, then run the implementation of gBrowser.getBrowserForDocument in the chrome window.
You'd save yourself a lot of time if you stopped writing C++ and switched to JS for such things.

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 am currently trying to access URL of the active window for Firebox browser using Pywinauto 0.6.0, as part of a python app that can track website usage. I am a newbie python programmer, so if I have made some obvious mistakes then this is why.
I have read all the material I can find on Google and the Pywinauto docs, but there are no clear indications of how to do this, atleast not without using "Typekeys" after connecting to a window.
In fact, I have been able to access to the URL the "hack" way by connecting to the browser window with pywinauto, then using "TypeKeys()" to grab the URL and copy it to clipboard. But this approach will not work for me, as it interrupts the user and my app must run in the background whilst the user is accessing their system as usual. Using the typekeys method introduces some odd mouse and window behaviour when changing or refreshing windows and then trying to grab the URL - so the approach has proven unworkable for me.
Currently the code I have is as follows (I have used the window text title='' of a specific window I am using for testing, in practice it is whichever the active tab on the browser is):
from pywinauto import *
app = application.Application()
app.connect(title=u'Facebook - Log In or Sign Up - Mozilla Firefox', found_index=0)
window = app.top_window_()
window.PrintControlIdentifiers()
titlebar = window.child_window(title=u'Facebook - Log In or Sign Up - Mozilla Firefox')
toolbar = titlebar.child_window(title=u'Navigation Toolbar')
combobox = toolbar.child_window(title=u'Search or enter address')
edit = combobox.child_window(title=u'Search or enter address')
I use PrintControlIdentifiers() in order to see which elements I can interact with, but this returns only
MozillaWindowClass - 'Facebook - Log In or Sign Up - Mozilla Firefox' (L-32000, T-32000, R-31840, B-31944)
[u'Facebook - Log In or Sign Up - Mozilla Firefox', u'MozillaWindowClass', u'Facebook - Log In or Sign Up - Mozilla FirefoxMozillaWindowClass']
I can access the Firefox Window fine with the current active tab, but next when trying to access the ChildWindow and subsequent ChildWindow there is no error, until I try and do something with the childwindow e.g., Click() function on what I think in the URL bar UI element. However, I am not sure even if the code is even accessing the child window element correctly in the first place. Or if this the right way to try and filter through the child elements to get to the URL edit control element.
As can be seen in the below image of the tree view of the UI elements (using UISPY.exe), the following tree to access the firefox browser edit control element that contains the URL is:
Tree view of Firefox UI elements via UISPY
"window" -> "title bar" -> "tool bar" "Navigation Toolbar" -> "combo box" -> "Search or enter address" -> "edit" "Search or enter address
where the "edit" control contains the attribute Value, Value:"url", which I need to extract to a variable.
Any help with this would greatly appreciated.
This is probably too late to post but incase any future developers has similiar question. Here is working solution.
Just pass backend='uia' as argument like application.Application(backend='uia'). Now, accessing and performing actions on child_window is possible.
Here is complete code snippet for any url.
url='https://google.com'
app = application.Application(backend='uia').connect(title_re=".*Mozilla Firefox")
main_firefox_winspec = app.window(title_re=".*Mozilla Firefox")
address_bar = main_firefox_winspec.child_window(title_re=".*or enter address", control_type="Edit")
address_bar.set_edit_text(url)
time.sleep(3)
main_firefox_winspec.child_window(title="Go to the address in the Location Bar").wrapper_object().click_input()
I need a qtf script that selects a line and proceeds. Recording the steps gave the following code:
Window("[windowname]").WinList("ListBox").Select "[Name of the item] "
But when I try to run it I see an error box: Cannot identify the specific item of the ListBox object.
This does not work with any of the lines. I cannot even select one with the arrow down key, the error is always the same.
Please try to highlight WinList from object repository before you run the script. If the object cannot be found, using an updating function to update the object property.
Also, make sure that every time you are running your script for standard window, your screen doesn't minimize.
I am running RStudio on a server and I created a RMarkdown (.Rmd) file. It works fine if I create it as a static HTML but it does not work if I want it to be interactive (by adding runtime:shiny).
The issue is that when I add runtime:shiny and press the Run Document button the application will try to open at 127.0.0.1:xxxx (here xxxx is a random port). In order to make it work I would have to be able to change the host parameter to '0.0.0.0'. This is an option in the runApp function from the shiny package but I don't know how to add this option in RMarkdown.
Can anyone help me with this?
Thank you.
The ::run command from rmarkdown invokes shiny::runApp internally. You can set the option shiny.host before running the document:
options(shiny.host="0.0.0.0")
rmarkdown::run("myfile.Rmd")
You an also pass arbitrary paramters to runApp, so this should work too:
rmarkdown::run("myfile.Rmd", shiny_args=list(host="0.0.0.0"))
Neither of these will work with the Run Document button; that button starts a new R session in which to render the document. To change the shiny.host option in that session, you'll need to add the option to your .Rprofile.
Set the default values you want to initialize in (~/.Rprofile) under user directory
Sys.setenv(TZ = "UTC") # for Timezone
options(shiny.port = 9999)
I am writing a small app that links into Umbraco (a small stand-alone console application that will eventually run as a scheduled task on the server) and I'm using the Umbraco APIs (4.5.2) to make changes to the database/document.
Here is a fragment of what I'm doing:
IEnumerable<Document> documents = Document.GetChildrenForTree(parentDocumentId);
foreach (Document doc in documents.Where(d => d.Published))
{
doc.getProperty("myData").Value = "some data"; // Exception here
// ...other stuff here...
}
However I always get a NullReferenceException because there are no properties. This confuses me because I can see that there are 5 properties in the umbraco interface.
A colleague suggested that I use a Node instead of a document, however I can't even create one as I get a NullReferenceException from the Node class constructor.
Node myNode = new Node(-1); // NullReferenceException here
Does anyone have any ideas?
The document class gets/sets information from the umbraco database. Since your running code in an out of band console application it can't find the umbraco context. Therefore throwing a null reference exception.
You need to run the code inside of the umbraco process. There is a asmx webservice that exists for third party integration. /umbraco/webservices/api/documentservice.asmx
Another way of achieving this could be to use linq2umbraco.
for further details see http://our.umbraco.org/forum/core/41-feedback/7699-UmbracoLinq-in-console-app--Having-some-troubles
I checked out the 4.5.2 source recently, to find that populating Document and Node objects only requires a connection using umbracoDbDsn. So if you have an AppSetting called umbracoDbDsn which points to a valid Umbraco database instance, you'll be good.
HTH,
Benjamin
