  • VS Intellisense: can you hide extension methods?

    - by chris
    By default Visual Studio displays all members and its extension methods for a type in intellisense. Sometimes I would like to hide the extension methods to make it easier to find the member I am actually looking for (especially when using Linq). Is there a shortcut or another way to display only the members of a type in intellisense?

  • Disable Intellisense in Blend 3

    - by KShaban
    We are currently building a WPF solution in Blend 3 and Intellisense is extremely slow. Visual Studio 2008 and 2010 beta 2 do not have any problems, Blend 2 did not have any issues either. How would it be possible to disable Intellisense in the XAML editor. Many Thanks, KShaban

  • Javascript in XSL that is loaded by Javascript

    - by James Armstead
    Is there anyway to have javascript run when a XSL sheet has been applied to an XML file by Javascript? I am using a JQuery plugin to apply the sheet to the xml but the javascript that is located inside of the XSL file will not run. I put the Javascript at the bottom of the file and it still does not run.. I can't seem to get an alert to even run?

  • Intellisense fails for boost::shared_ptr with Boost 1.40.0 in Visual Studio 2008

    - by Edward Loper
    I'm having trouble getting intellisense to auto-complete shared pointers for boost 1.40.0. (It works fine for Boost 1.33.1.) Here's a simple sample project file where auto-complete does not work: #include <boost/shared_ptr.hpp> struct foo { bool func() { return true; }; }; void bar() { boost::shared_ptr<foo> pfoo; pfoo.get(); // <-- intellisense does not autocomplete after "pfoo." pfoo->func(); // <-- intellisense does not autocomplete after "pfoo->" } When I right-click on shared_ptr, and do "Go to Definition," it brings be to a forward-declaration of the shared_ptr class in . It does not bring me to the actual definition, which is in However, it compiles fine, and auto-completion works fine for "boost::." Also, auto-completion works fine for boost::scoped_ptr and for boost::shared_array. Any ideas?

  • using javascript onchange to fill a calendar

    - by scatman
    i have a calendar and a textbox in my c# asp.net application. when a user enters a date in the textbox, the selected date in the calendar should become the date entered in the text box. the hard part is that i need to do this in javascript. what i have now is this: <asp:TextBox ID="txtDate" runat="server" onchange="javascript: Changed( this );" /> <asp:Calendar ID="calDate" runat="server" /> <script type="text/javascript"> var calendarID = ''; function Changed(textControl) { var date = Date.parse(textControl.value); //this is giving me the date in seconds var cal = document.getElementById(calendarID); } </script> and i am setting calendarID in this way: <script type="text/javascript"> calendarID = "<%=calDate.ClientID%>"; </script> there is no cal.selectedDate or anything like this... any help?

  • DIY intellisense on XPath - design approach? (WinForms app)

    - by Cheeso
    I read the DIY Intellisense article on code project, which was referenced from the Mimic Intellisense? question here on SO. I wanna do something similar, DIY intellisense, but for XPath not C#. The design approach used there makes sense to me: maintain a tree of terms, and when the "completion character" is pressed, in the case of C#, a dot, pop up the list of possible completions in a textfield. Then allow the user to select a term from the textfield either through typing, arrow keys, or double-click. How would you apply this to XPath autocompletion? should there be an autocomplete key? In XPath there is no obvious separator key like "dot" in C#. should the popup be triggered explicitly in some other way, let's say ctrl-. ? or should the parser try to autocomplete continuously? If I do the autocomplete continuously, how to scale it properly? There are 93 xpath functions, not counting overloads. I certainly don't want to popup a list of 93 choices. How do I decide when I've narrowed it enough to offer a useful lsit of possible completions? How to populate the tree of possible completions? For C#, it's easy: walk the type space via reflection. At a first level, the "syntax tree" for C# seems like a single tree, and the list of completions at any point depends on the graph of nodes you've traversed to that point. Typing System.Console. traverses to a certain node in that tree, and the list of completions is the set of child nodes available at that node in the tree. On the other hand, the xpath syntax seems like it is a "flatter" tree - function names, axis names, literals. Does this make sense? what have I not considered?

  • Javascript clears a variable after there is no further reference it

    - by Praveen Prasad
    It is said, javascript clears a variable from memory after its being referenced last. just for the sake of this question i created a JS file with only one variable; //file start //variable defined var a=["Hello"] //refenence to that variable alert(a[0]); // //file end no further reference to that variable, so i expect javascript to clear varaible 'a' Now i just ran this page and then opened firebug and ran this code alert(a[0]); Now this alerts the value of variable, If the statement "Javascript clears a variable after there is no further reference it" is true how come alert() shows its value. Is it because all variable defined in global context become properties of window object, and since even after the execution file window objects exist so does it properties.

  • JavaScript Data Binding Frameworks

    - by dwahlin
    Data binding is where it’s at now days when it comes to building client-centric Web applications. Developers experienced with desktop frameworks like WPF or web frameworks like ASP.NET, Silverlight, or others are used to being able to take model objects containing data and bind them to UI controls quickly and easily. When moving to client-side Web development the data binding story hasn’t been great since neither HTML nor JavaScript natively support data binding. This means that you have to write code to place data in a control and write code to extract it. Although it’s certainly feasible to do it from scratch (many of us have done it this way for years), it’s definitely tedious and not exactly the best solution when it comes to maintenance and re-use. Over the last few years several different script libraries have been released to simply the process of binding data to HTML controls. In fact, the subject of data binding is becoming so popular that it seems like a new script library is being released nearly every week. Many of the libraries provide MVC/MVVM pattern support in client-side JavaScript apps and some even integrate directly with server frameworks like Node.js. Here’s a quick list of a few of the available libraries that support data binding (if you like any others please add a comment and I’ll try to keep the list updated): AngularJS MVC framework for data binding (although closely follows the MVVM pattern). Backbone.js MVC framework with support for models, key/value binding, custom events, and more. Derby Provides a real-time environment that runs in the browser an in Node.js. The library supports data binding and templates. Ember Provides support for templates that automatically update as data changes. JsViews Data binding framework that provides “interactive data-driven views built on top of JsRender templates”. jQXB Expression Binder Lightweight jQuery plugin that supports bi-directional data binding support. KnockoutJS MVVM framework with robust support for data binding. For an excellent look at using KnockoutJS check out John Papa’s course on Pluralsight. Meteor End to end framework that uses Node.js on the server and provides support for data binding on  the client. Simpli5 JavaScript framework that provides support for two-way data binding. WinRT with HTML5/JavaScript If you’re building Windows 8 applications using HTML5 and JavaScript there’s built-in support for data binding in the WinJS library.   I won’t have time to write about each of these frameworks, but in the next post I’m going to talk about my (current) favorite when it comes to client-side JavaScript data binding libraries which is AngularJS. AngularJS provides an extremely clean way – in my opinion - to extend HTML syntax to support data binding while keeping model objects (the objects that hold the data) free from custom framework method calls or other weirdness. While I’m writing up the next post, feel free to visit the AngularJS developer guide if you’d like additional details about the API and want to get started using it.

  • What should JavaScript be renamed to [closed]

    - by Evan Plaice
    Background: I have been watching Douglas Crockford's series of presentation about JavaScript History (which I highly recommend) lately and a one comment of his specifically piqued my attention. The trademark for 'JavaScript' is owned by Oracle History: Due to time constraints at Netscape, the language was literally written in weeks and released in very buggy form. To make it seem more appealing, Netscape picked JavaScript to appeal to the massively growing population of Java developers. Unfortunately, this pissed off Sun and stirred up a lot of controversy between the two organizations. At some point, they came to an agreement whereby Netscape was given permission to use the name as long as Sun owned the trademark. Some people incorrectly refer to JavaScript as ECMAScript because that's where the standard for the language is registered but, aside from it's current marketing-driven label, it doesn't really have a name. Fast Forward Sun goes down only to be swallowed by Oracle, who has no reservations about litigating for profit, now owns the name. So... If Oracle decides and forces JavaScript to take on a new name, what name would best represent the language?

  • Performance: recursion vs. iteration in Javascript

    - by mastazi
    I have read recently some articles (e.g. http://dailyjs.com/2012/09/14/functional-programming/) about the functional aspects of Javascript and the relationship between Scheme and Javascript (the latter was influenced by the first, which is a functional language, while the O-O aspects are inherited from Self which is a prototyping-based language). However my question is more specific: I was wondering if there are metrics about the performance of recursion vs. iteration in Javascript. I know that in some languages (where by design iteration performs better) the difference is minimal because the interpreter / compiler converts recursion into iteration, however I guess that probably this is not the case of Javascript since it is, at least partially, a functional language.

  • data handling with javascript

    - by Vincent Warmerdam
    Python has a very neat package called pandas which allows for quick data transformation; tables, aggregation, that sort of thing. A lot of these types of functionality can also be found in the python itertools module. The plyR package in R is also very similar. Usually one woud use this functionality to produce a table which is later visualized with a plot. I am personally very fond of d3, and I would like to allow the user to first indicate what type of data aggregation he wants on the dataset before it is visualized. The visualisation in question involves making a heatmap where the user gets to select the size of the bins of the heatmap beforehand (I want d3 to project this through leaflet). I want to visually select the ideal size of the bins for the heatmap. The way I work now is that I take the dataset, aggregate it with python and then manually load it in d3. This is a process that takes a lot of human effort and I was wondering if the data aggregation can be done through the javascript of the browser. I couldn't find a package for javascript specifically built for data, suggesting (to me) that this is a bad idea and that one should not use javascript for the data handling. Is there a good module/package for javascript to handle data aggregation? Is it a good/bad idea to do the data aggregation in javascript (performance wise)?

  • JavaScript evolution -- weeding out the confusion [closed]

    - by good_computer
    There was JavaScript v1.3 (I guess) that we all started with. Then there was JavaScript 2.0 that Adobe implemented (ActionScript) but was abandoned later. Then came E4X. Then ES5. There is also ES harmony. I am really confused about which version is the latest and where is the standards body going. Can someone describe the whole chronology of JavaScript / ECMAScript evolution and the important differences between those versions?

  • XML/XSD intellisense not working in Visual Studio 2010

    - by Jason
    I am working on xml and xsd files in VS 2010 but intellisense isn't working. Intellisense is working for the same files in VS 2008, however. When I type '<xs:' options like "attribute", "complexType", "simpleType", or "element" do not appear. Is there some difference between the VS 2008 and VS 2010 that I'm missing? I add an xsd file to my solution. All the proper namespaces are generated automatically as such: <?xml version="1.0" encoding="utf-8"?> <xs:schema id="XMLSchema2" targetNamespace="http://tempuri.org/XMLSchema2.xsd" elementFormDefault="qualified" xmlns="http://tempuri.org/XMLSchema2.xsd" xmlns:mstns="http://tempuri.org/XMLSchema2.xsd" xmlns:xs="http://www.w3.org/2001/XMLSchema"> </xs:schema> The "xsdschema.xsd" is in the "C:\Program Files\Microsoft Visual Studio 10.0\xml\Schemas" directory. There is a check mark in the "Use" column in the XML Schemas dialog box.

  • IntelliSense and Folding Editor Not Working in Visual Studio 2008 SP1 for Certain Files Only

    - by cplotts
    Ok, I have an issue that is driving me nuts. In certain xaml files only, neither IntelliSense nor the folding editor is working. I have noticed that if I delete the local namespace and add it back, the folding editor starts working. If I delete the local namespace and don't add it back, IntelliSense starts working as well. Of course, I need to remember to add that namespace declaration back before I compile and/or check in ... which is annoying. How can you fix this?

  • Intellisense in header files

    - by David
    I just right now "migrated" from C# to C++/CLR. First I was annoyed, that I had to write all class' declarations twice (into .h and .cpp). Then I figured out, that I could place the code also into the h-files - it compiles at least. Well, I deleted all cpp's of my classes and now I realized, VS won't give me any Intellisense when I work on my h-files. I guess I should not place my code in the hfiles (the code won't be reused in other projects for sure), but I find it terrible to adjust all method declarations at two places... Plus I have to switch back and forth to see what modifier my method etc. and it is not nicely all in one place like in C# (with it's pros and cons). I'm sorry this is a newbie question, but I just wanted to make sure that there isn't any possibility to enable intellisense for hfiles. Or at least to learn, that I am completely on the wrong path... Thanks, David

  • JAVASCRIPT changing on click

    - by Webby
    Hello, Id like some help changing this javascript onclick event to just load the data on page the page load... Preferably not using the body on load tag... So obviously I'd pre set the var for term inside the script term rather than the excisting on click event.. Hope that made sense <p><a id="keywordlink" href="?term=wombats">Get keywords for wombats</a></p> <script type="text/javascript" src="keywords.js"></script> <script type="text/javascript"> var x = document.getElementById('keywordlink'); if(x){ x.onclick = function(){ var term = this.href.split('=')[1]; this.innerHTML += ' (loading...)'; KEYWORDS.get(term,seed); return false; } } function seed(o){ var div = document.createElement('div'); var head = document.createElement('h2'); head.innerHTML = 'Keywords for '+o.term; div.appendChild(head); var p = document.createElement('p'); p.innerHTML = o.toplist; div.appendChild(p); var head = document.createElement('h3'); head.innerHTML = 'Details:'; div.appendChild(head); var list = document.createElement('ol'); for(var i=0,j=o.keywords.length;i<j;i++){ var li = document.createElement('li'); li.innerHTML = o.keywords[i].term + '('+o.keywords[i].amount+')'; list.appendChild(li); } div.appendChild(list); x.parentNode.replaceChild(div,x); } </script>

  • How often do you find javascript disabled on browsers?

    - by Mark Redman
    I have started using ajax/jQuery in our websites / application. There are many plugins that support degrading the javascript to browsers that dont have javascript enabled and techniques to support this. What are peoples thoughts on javascript support, we build applications rather than just websites and are looking to just support javascript enabled browsers as a pre-requisite assuming that most people or companies have javascript enabled. Do you find most people have javascript? do you monitor the percentage of javascript/non-javascript browsers (I guess this can be done with website stats) and what are the numbers regarding this?

  • Scope of This JavaScript Variable

    - by dkris
    I have a question and an issue wrt the code below: My question is what is the scope of the variable loaded here. The reason why i ask this is the onload="if(loaded==1)inittextarea() code is working fine on Firefox and not IE8. Why is this happening? Is there something specific i need to do here? Or is it not a valid practice? <html> <head> <title>Some Page</title> <link rel="stylesheet" href="../css/default.css" type="text/css"> <script type="text/javascript"> var loaded = 0; /*Point of interest*/ function jsLoaded() { loaded =1; } </script> <script type="text/javascript"> function inittextarea() { alert("test") tinyMCE.init({ elements : "content", theme : "advanced", readonly : true, mode : "exact", theme : "advanced", readonly : true, setup : function(ed) { ed.onInit.add(function() { tinyMCE.activeEditor.execCommand("mceToggleVisualAid"); }); } }); } </script> <script src="../js/tiny_mce/tiny_mce.js" onload="jsLoaded()" type="text/javascript"></script> </head> <body onload="if(loaded==1)inittextarea()"><!--Works on Firefox only--> *Usual stuff* </body></html> Any pointers please?
