I'm tyring to call the method checkCurrentDictionary() of nsIEditorSpellCheck from within an add-on. The relevant code I use is:
var editorSpellCheck = Cc["#mozilla.org/editor/editorspellchecker;1"].createInstance(Ci.nsIEditorSpellCheck);
editorSpellCheck.checkCurrentDictionary();
This immediately crashes the Fx. What is going wrong here?
So this probably has something to do with the fact that nsIEditorSpellCheck is not a scriptable interface.
Basically, a scriptable interface is one that can be used from JavaScript.
If you want to access the spell check service you can do something like:
let editor = editableElement.editor;
if (!editor) {
let win = editableElement.ownerDocument.defaultView;
editor = win.QueryInterface(Ci.nsIInterfaceRequestor).
getInterface(Ci.nsIWebNavigation).
QueryInterface(Ci.nsIInterfaceRequestor).
getInterface(Ci.nsIEditingSession).
getEditorForWindow(win);
}
if (!editor)
throw new Error("Unable to find editor for element " + editableElement);
(The above is from http://dxr.mozilla.org/mozilla-central/source/editor/AsyncSpellCheckTestHelper.jsm which is MPL).
Then you can use the InlineSpellCheck.jsm to do some crazy stuff.
I'm not sure what you want to do though, so perhaps you should ask that more specific question as a new question.

I am currently working on selenium using ruby.
Is there any way to focus on a new window from an application?
Thanks!
I'm not aware of Ruby, but this what you can do in JAVA. See if you can implement similar logic in RUBY.
String parentHandle= driver.getWindowHandle();//Return parent window handle
for (String handle : driver.getWindowHandles()) {
driver.switchTo().window(handle);
}
driver.close(); // close newly opened window
driver.switchTo().window(parentHandle); // switch back to the parent window
Unfortunately, I cannot leave comments, or else I would point you to both of these websites:
API examples: http://docs.seleniumhq.org/docs/03_webdriver.jsp -> ruby option
API docs: http://seleniumhq.github.io/selenium/docs/api/rb/Selenium/WebDriver/Window.html
http://seleniumhq.github.io/selenium/docs/api/rb/Selenium/WebDriver/Driver.html
Here is a direct translation of the code by abhijeet in case you are wondering how it may look like in ruby.
parent_handle = driver.window_handle
driver.window_handles.each do |handle|
driver.switch_to.window handle
end
driver.close
driver.switch_to.window(parent_handle)
I'm trying to make a simple feature where a user can specify a term and the program fetches a definition for it and returns it. The best definition system I know of is Google's "define" keyword in search queries where if you start the query with "define " or "define:" etc it returns very accurate and sufficient definitions. However, I have no idea how to access this information programatically.
Google's new Custom Search Engine API doesn't show definitions and the old one gives slightly better results but is deprecated and still doesn't show the same definitions I see when I Google the term in the browser.
Failing Google, I turned to Wikipedia, which has a huge API but I still couldn't find a way to extract summaries like Google definitions.
So my question is, does anybody know how I can get this information out of Google via the API or any other means?
This is an older question but is asking the same thing. Except the answers given are no longer applicable as Google Dictionary no longer exists.
Update: So I'm now going down the route of trying to scrape the definitions straight out of the page itself. Now the problem is, when I visit the page in the browser (Firefox), the definitions show up, but when I'm scraping them using cheerio, they don't show up anywhere on the page. I must mention I'm scraping the page through nitrous.io so it's rendering the page from a different region and operating system to the one I'm viewing it in the browser with so maybe it's region related. Will look into it further.
Update 2.0: I think maybe the definitions are loaded asynchronously and so I have no idea how to scrape them because I've never really done scraping before and I'm just a newbie :(
Update 3.0: Ok, so now I think it's not to do with the asynchronous loading but the renderer of the page. When I load this in Firefox, the page looks like this:
However, when I load it in IE (8) it looks like this:
Anybody got some insight on this?
Finally got to the answer. Had to set user agent when screen scraping. My resulting code for getting definitions via scraping:
var request = require('request')
, cheerio = require('cheerio');
var searchTerm = 'test';
request({url:'https://www.google.co.uk/search?q=define+'+searchTerm,headers:{"User-Agent":"Mozilla/5.0 (Windows NT 6.1; WOW64; rv:24.0) Gecko/20100101 Firefox/24.0"}}, function(err, resp, body){
$ = cheerio.load(body);
var defineBlocks = $(".lr_dct_sf_sen");
var numOfBlocks = (defineBlocks.length < 3) ? defineBlocks.length : 3;
for (var i=0; i<numOfBlocks; i++){
var block = defineBlocks[i].children[1].children[0]; //font-size:small level
process(block);
function process (block) {
for (var i=0; i<block.children.length; i++){
var line = block.children[i];
if ("style" in line.attribs){ // main text
exampleStr = "";
for (var k=0; k<line.children.length; k++){
exampleStr += line.children[k].children[0].data;
}
console.log(exampleStr);
} else if ("class" in line.attribs){ // example
console.log("\""+line.children[1].children[0].data+"\"");
} else { // nothing i want
}
}
}
}
});
I recorded some test cases with CUIT in VS2010. Everything worked fine the day before. So, today I run again, all the test failed, with the warning: The following element is no longer available ... and I got the exception : Can't perform "Click" on the hidden control, which is not true because all the controls are not hidden. I tried on the other machine, and they failed as well.
Does anyone know why it happens? Is it because of the web application for something else? Please help, thanks.
PS: So I tried to record a new test with the same controls that said "hidden controls", and the new test worked!? I don't understand why.
EDIT
The warning "The following element blah blah ..." appears when I tried to capture an element or a control while recording. The source code of the button is said 'hidden'

Although I am running Visual Studio 2012, I find it odd that we started experiencing the same problem on the same day, I can not see any difference in the DOM for the Coded UI Tests I have for my web page, but for some reason VS is saying the control is hidden and specifies the correct ID of the element it is looking for (I verified that the ID is still the same one). I even tried to re-record the action, because I assumed that something must have changed, but I get the same error.
Since this sounds like the same problem, occurring at the same time I am thinking this might be related to some automatic update? That's my best guess at the moment, I am going to look into it, I will update my post if I figure anything out.
EDIT
I removed update KB2870699, which removes some voulnerability in IE, this fixed the problems I was having with my tests. This update was added on the 12. september, so it fits. Hope this helps you. :)
https://connect.microsoft.com/VisualStudio/feedback/details/800953/security-update-kb2870699-for-ie-breaks-existing-coded-ui-tests#tabs
Official link to get around the problem :
http://blogs.msdn.com/b/visualstudioalm/archive/2013/09/17/coded-ui-mtm-issues-on-internet-explorer-with-kb2870699.aspx
The problem is more serious than that! In my case I can't even record new Coded UI Tests. After I click in any Hyper Link of any web page of my application the coded UI test builder cannot record that click "The following element is no longer available....".
Apparently removing the updates, as said by AdrianHHH do the trick!
Shut down VS2010, launch it again "Run as administrator".
There may be a field in the SearchProperties (or possible the FilterProperties) that has a value set by the web site, or that represents some kind of window ID on your desktop. Another possibility is that the web page title changes from day to day or visit to visit. Different executions of the browser or different visits to the web page(s) create different values. Removing these values from the SearchProperties (or FilterProperties) or changing the check for the title from an equals to a contains for a constant part of the title should fix the problem. Coded UI often searches for more values than the minimum set needed.
Compare the search properties etc for the same control in the two recorded tests.
Update based extra detail given in the comments:
I solved a similar problem as follows. I copied property code similar to that shown in your question into a method that called FindMatchingControls. I checked how many controls were returned, in my case up to 3. I examined various properties of the controls found, by writing lots of text to a debug file. In my case I found that the Left and Top properties were negative for the unwanted, ie hidden, controls.
For your code rather than just using the UIAbmeldenImage property, you might call the method below. Change an expression such as
HtmlImage im = UIMap.abc.def.UIAbmeldenImage;
to be
HtmlImage im = FindHtmlHyperLink(UIMap.abc.def);
Where the method is:
public HtmlImage FindHtmlHyperLink(HtmlDocument doc)
{
HtmlImage myImage = new HtmlImage(doc);
myImage.SearchProperties[HtmlImage.PropertyNames.Id] = null;
myImage.SearchProperties[HtmlImage.PropertyNames.Name] = null;
myImage.SearchProperties[HtmlImage.PropertyNames.Alt] = "abmelden";
myImage.FilterProperties[HtmlImage.PropertyNames.AbsolutePath] = "/webakte-vnext/content/apps/Ordner/images/logOut.png";
myImage.FilterProperties[HtmlImage.PropertyNames.Src] = "http://localhost/webakte-vnext/content/apps/Ordner/images/logOut.png";
myImage.FilterProperties[HtmlImage.PropertyNames.LinkAbsolutePath] = "/webakte-vnext/e.consult.9999/webakte/logout/index";
myImage.FilterProperties[HtmlImage.PropertyNames.Href] = "http://localhost/webakte-vnext/e.consult.9999/webakte/logout/index";
myImage.FilterProperties[HtmlImage.PropertyNames.Class] = null;
myImage.FilterProperties[HtmlImage.PropertyNames.ControlDefinition] = "alt=\"abmelden\" src=\"http://localhost/web";
myImage.FilterProperties[HtmlImage.PropertyNames.TagInstance] = "1";
myImage.WindowTitles.Add("Akte - Test Akte Coded UI VS2010");
UITestControlCollection controls = myImage.FindMatchingControls();
if (controls.Count > 1)
{
foreach (UITestControl con in controls)
{
if ( con.Left < 0 || con.Top < 0 )
{
// Not on display, ignore it.
}
else
{
// Select this one and break out of the loop.
myImage = con as HtmlImage;
break;
}
}
}
return myImage;
}
Note that the above code has not been compiled or tested, it should be taken as ideas not as the final code.
I had the same problem on VS 2012. As a workaround, you can remove that step, and re-record it again. That usually works.
One of the biggest problem while analyzing the Coded UI test failures is that the error stack trace indicates the line of code which might be completely unrelated to the actual cause of failure.
I would suggest you to enable HTML logging in your tests - this will display step by step details of how Coded UI tried to execute the tests - with screenshots of your application. It will also highlight the control in red which Coded UI is trying to search/operate upon.This is very beneficial in troubleshooting the actual cause of test failures.
To enable tracing you can just add the below code to your app.config file --
In Visual Studio debug mode it's possible to hover over variables to show their value and then right-click to "Copy", "Copy Expression" or "Copy Value".
In case the variable is an object and not just a basic type, there's a + sign to expand and explore the object. It there a way to copy all that into the clipboard?
In the immediate window, type
?name_of_variable
This will print out everything, and you can manually copy that anywhere you want, or use the immediate window's logging features to automatically write it to a file.
UPDATE: I assume you were asking how to copy/paste the nested structure of the values so that you could either search it textually, or so that you can save it on the side and then later compare the object's state to it. If I'm right, you might want to check out the commercial extension to Visual Studio that I created, called OzCode, which lets you do these thing much more easily through the "Search" and "Compare" features.
UPDATE 2 To answer #ppumkin's question, our new EAP has a new Export feature allows users to Export the variable values to Json, XML, Excel, or C# code.
Full disclosure: I'm the co-creator of the tool I described here.
You can run below code in immediate window and it will export to an xml file the serialized XML representation of an object:
(new System.Xml.Serialization.XmlSerializer(obj.GetType())).Serialize(new System.IO.StreamWriter(#"c:\temp\text.xml"), obj)
Source: Visual Studio how to serialize object from debugger
Most popular answer from https://stackoverflow.com/a/23362097/2680660:
With any luck you have Json.Net in you appdomain already. In which
case pop this into your Immediate window:
Newtonsoft.Json.JsonConvert.SerializeObject(someVariable)
Edit: With .NET Core 3.0, the following works too:
System.Text.Json.JsonSerializer.Serialize(someVariable)
There is a extension called Object Exporter that does this conveniently.
http://www.omarelabd.net/exporting-objects-from-the-visual-studio-debugger/
Extension: https://visualstudiogallery.msdn.microsoft.com/c6a21c68-f815-4895-999f-cd0885d8774f
You can add a watch for that object, and in the watch window, expand and select everything you want to copy and then copy it.
By using attributes to decorate your classes and methods you can have a specific value from your object display during debugging with the DebuggerDisplay attribute e.g.
[DebuggerDisplay("Person - {Name} is {Age} years old")]
public class Person
{
public string Name { get; set; }
public int Age { get; set; }
}
I always use:
string myJsonString = JsonConvert.SerializeObject(<some object>);
Then I copy the string value which unfortunately also copies the back slashes.
To remove the backlashes go here:
https://www.w3schools.com/jsref/tryit.asp?filename=tryjsref_replace
Then within the <p id="demo">Visit Microsoft!</p> element replace the text with the text you copied.
then replace the var res = str.replace("Microsoft", "W3Schools"); line with
var res = str.replace(/\\/g, '')
Run these new changes but don't forget to click the "try it" button on the right.
Now you should have all the text of the object in json format that you can drop in a json formatter like http://jsonformatter.org or to create a POCO you can now use http://json2csharp.com/
ObjectDumper.NET
This is an awesome way!
You probably need this data for a unit test, so create a Sandbox.cs temporary test or you can create a Console App.
Make sure to get NuGet package, ObjectDumper.NET, not ObjectDumper.
Run this test (or console app)
View test output or text file to get the C# initializer code!
Code:
[TestClass]
public class Sandbox
{
[TestMethod]
public void GetInitializerCode()
{
var db = TestServices.GetDbContext();
var list = db.MyObjects.ToList();
var literal = ObjectDumper.Dump(list, new DumpOptions
{
DumpStyle = DumpStyle.CSharp,
IndentSize = 4
});
Console.WriteLine(literal); // Some test runners will truncate this, so use the file in that case.
File.WriteAllText(#"C:\temp\dump.txt", literal);
}
}
I used to use Object Exporter, but it is 5 years old and no longer supported in Visual Studio. It seems like Visual Studio Extensions come and go, but let's hope this NuGet package is here to stay! (Also it is actively maintained as of this writing.)
Google led me to this 8-year-old question and I ended up using ObjectDumper to achieve something very similar to copy-pasting debugger data. It was a breeze.
I know the question asked specifically about information from the debugger, but ObjectDumper gives information that is basically the same. I'm assuming those who google this question are like me and just need the data for debugging purposes and don't care whether it technically comes from the debugger or not.
I know I'm a bit late to the party, but I wrote a JSON implementation for serializing an object, if you prefer to have JSON output. Uses Newtonsoft.Json reference.
private static void WriteDebugJSON (dynamic obj, string filePath)
{
using (StreamWriter d = new StreamWriter(filePath))
{
d.Write(JsonConvert.SerializeObject(obj));
}
}
I've just right clicked on the variable and selected AddWatch, that's bring up watch window that consists of all the values. I selected all and paste it in a text a text editor, that's all.
Object Dumper is a free and open source extension for Visual Studio and Visual Studio Code.
"Dump as" commands are available via context menu in the Code and Immediate windows.
It's exporting objects to:
C# object initialization code,
JSON,
Visual Basic object initialization code,
XML,
YAML.
I believe that combined with the Diff tool it can be helpful.
I'm the author of this tool.
if you have a list and you want to find a specific variable:
In the immediate window, type
myList.Any(s => s.ID == 5062);
if this returns true
var myDebugVar = myList.FirstOrDefault(s => s.ID == 5062);
?myDebugVar
useful tips here, I'll add my preference for when i next end up here asking this question again in the future.
if you don't mind adding an extension that doesn't require output files or such there's the Hex Visualizer extension for visual studio, by mladen mihajlovic, he's done versions since 2015.
provides a nice display of the array via the usual magnifine glass view object from the local variables window.
https://marketplace.visualstudio.com/items?itemName=Mika76.HexVisualizer2019 is the 2019 version.
If you're in debug mode, you can copy any variable by writing copy() in the debug terminal.
This works with nested objects and also removes truncation and copies the complete value.
Tip: you can right click a variable, and click Copy as Expression and then paste that in the copy-function.
System.IO.File.WriteAllText("b.json", page.DebugInfo().ToJson())
Works great to avoid to deal with string debug format " for quote.
As #OmerRaviv says, you can go to Debug → Windows → Immediate where you can type:
myVariable
(as #bombek pointed out in the comments you don't need the question mark) although as some have found this limits to 100 lines.
I found a better way was to right click the variable → Add Watch, then press the + for anything I wanted to expand, then used #GeneWhitaker's solution, which is Ctrl+A, then copy Ctrl+C and paste into a text editor Ctrl+V.
I'm making a small file-browser for my own use, in Ruby, and using Qt for the view. The idea is that it'll end up on my TV, where I can use the remote to move up and down and launch files.
Everything works fine, until I'm going to move the selection using the remote. I managed to set up a D-Bus service, so I'll just call the methods using LIRC.
The code I'm using for setting up the view looks like this:
#dm = Qt::DirModel.new
#sm = Qt::ItemSelectionModel.new(#dm)
#lv = Qt::ListView.new
#lv.model = #dm
#lv.selectionModel = #sm
cwd = #dm.index(#dir)
#lv.rootIndex = cwd
And then I'm unsure how to change the selection. Think I must have tried about every setIndex, setSelection and every method sounding similar, on the DirModel, ItemSelectionModel and ListView, without any luck. I've been googling and reading through the API without finding anything.
Ideally, I would have something like "moveSelectionDown" and "moveSelectionUp" that takes care of it, and making sure it wraps around correctly. But I can't seem to find anything.
Managed to fix it through the ItemSelectionModel every view apparently has.
moving up:
curIndex = #lv.currentIndex
#lv.selectionModel.setCurrentIndex(curIndex.sibling(curIndex.row-1, 0), Qt::ItemSelectionModel::ClearAndSelect)
or adding one to move down
I think you're forgetting that you have to create the ModelIndex through your model:
#dm.index(3, 0, None)
I'd try this method (Though I'm not really sure, this deselects the other cells.)
#lv.setCurrentIndex(#dm.index(3, 0, None))
I haven't used Ruby for ages, so I'm not exactly sure there's None.
