  • Adding Help to a Cocoa App

    - by enchilada
    I want to add a simple one-page HTML page help to my Cocoa app. Can you tell me how to do it? I assume I just have to throw in one lousy .html (and maybe one .css?) file somewhere into my Cocoa project in Xcode?

  • How can I make the C# compiler infer these type parameters automatically?

    - by John Feminella
    I have some code that looks like the following. First I have some domain classes and some special comparators for them. public class Fruit { public int Calories { get; set; } public string Name { get; set; } } public class FruitEqualityComparer : IEqualityComparer<Fruit> { // ... } public class BasketEqualityComparer : IEqualityComparer<IEnumerable<Fruit>> { // ... } Next, I have a helper class called ConstraintChecker. It has a simple BaseEquals method that makes sure some simple base cases are considered: public static class ConstraintChecker { public static bool BaseEquals(T lhs, T rhs) { bool sameObject = l == r; bool leftNull = l == null; bool rightNull = r == null; return sameObject && !leftNull && !rightNull; } There's also a SemanticEquals method which is just a BaseEquals check and a comparator function that you specify. public static bool SemanticEquals<T>(T lhs, T rhs, Func<T, T, bool> f) { return BaseEquals(lhs, rhs) && f(lhs, rhs); } And finally there's a SemanticSequenceEquals method which accepts two IEnumerable<T> instances to compare, and an IEqualityComparer instance that will get called on each pair of elements in the list via Enumerable.SequenceEquals. public static bool SemanticSequenceEquals<T, U, V>(U lhs, U rhs, V comparator) where U : IEnumerable<T> where V : IEqualityComparer<T> { return SemanticEquals(lhs, rhs, (l, r) => lhs.SequenceEqual(rhs, comparator)); } } // end of ConstraintChecker The point of SemanticSequenceEquals is that you don't have to define two comparators whenever you want to compare both IEnumerable<T> and T instances; now you can just specify an IEqualityComparer<T> and it will also handle lists when you invoke SemanticSequenceEquals. So I could get rid of the BasketEqualityComparer class, which would be nice. But there's a problem. The C# compiler can't figure out the types involved when you invoke SemanticSequenceEquals: return ConstraintChecker.SemanticSequenceEquals(lhs, rhs, new FruitEqualityComparer()); If I specify them explicitly, it works: return ConstraintChecker.SemanticSequenceEquals< Fruit, IEnumerable<Fruit>, IEqualityComparer<Fruit> > (lhs, rhs, new FruitEqualityComparer()); What can I change here so that I don't have to write the type parameters explicitly?

  • How to "enable" HTML5 elements in IE that were inserted by AJAX call?

    - by Gidon
    IE does not work good with unknown elements (ie. HTML5 elements), one cannot style them , or access most of their props. Their are numerous work arounds for this for example: http://remysharp.com/2009/01/07/html5-enabling-script/ The problem is that this works great for static HTML that was available on page load, but when one creates HTML5 elements afterward (for example AJAX call containing them, or simply creating with JS), it will mark these newly added elements them as HTMLUnknownElement as supposed to HTMLGenericElement (in IE debugger). Does anybody know a work around for that, so that newly added elements will be recognized/enabled by IE? Here is a test page: <html><head><title>TIME TEST</title> <!--[if IE]> <script src="http://html5shiv.googlecode.com/svn/trunk/html5.js"></script> <![endif]--> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js" type="text/javascript"></script> </head> <body> <time>some time</time> <hr> <script type="text/javascript"> $("time").text("WORKS GREAT"); $("body").append("<time>NEW ELEMENT</time>"); //simulates AJAX callback insertion $("time").text("UPDATE"); </script> </body> </html> In IE you will see the: UPDATE , and NEW ELEMENT. In any other modern browser you will see UPDATE, and UPDATE Solution Using the answer provided I came up with the following piece of javascript to HTML5 enable a whole bunch of elements returned by my ajax call: (function ($) { jQuery.fn.html5Enable = function () { if ($.browser.msie) { $("abbr, article, aside, audio, canvas, details, figcaption, figure, footer, header, hgroup, mark, menu, meter, nav, output, progress, section, summary, time, video", this).replaceWith(function () { if (this.tagName == undefined) return ""; var el = $(document.createElement(this.tagName)); for (var i = 0; i < this.attributes.length; i++) el.attr(this.attributes[i].nodeName, this.attributes[i].nodeValue); el.html(this.innerHtml); return el; }); } return this; }; })(jQuery); Now this can be called whenever you want to append something: var el = $(AJAX_RESULT_OR_HTML_STRING); el.html5Enable(); $("SOMECONTAINER").append(el); See http://code.google.com/p/html5shiv/issues/detail?id=4 for an explanation about what this plugin doesn't do.

  • Smooth scrolling and syntax highlighting in MacVim

    - by mitjak
    Is there any way to get MacVim to scroll more smoothly TextMate style? While I'm here, is there a syntax file I can edit to add syntax highlighting to files? I have Velocity .vhtml files which are largely regular HTML with a bit of VTL thrown in. If I could just add .vhtml as an extension to the HTML syntax highlighter that would already make things 10x better.

  • How can I configure a Factory with the possible providers?

    - by Jonathas Costa
    I have three assemblies: "Framework.DataAccess", "Framework.DataAccess.NHibernateProvider" and "Company.DataAccess". Inside the assembly "Framework.DataAccess", I have my factory (with the wrong implementation of discovery): public class DaoFactory { private static readonly object locker = new object(); private static IWindsorContainer _daoContainer; protected static IWindsorContainer DaoContainer { get { if (_daoContainer == null) { lock (locker) { if (_daoContainer != null) return _daoContainer; _daoContainer = new WindsorContainer(new XmlInterpreter()); // THIS IS WRONG! THIS ASSEMBLY CANNOT KNOW ABOUT SPECIALIZATIONS! _daoContainer.Register( AllTypes.FromAssemblyNamed("Company.DataAccess") .BasedOn(typeof(IReadDao<>)).WithService.FromInterface(), AllTypes.FromAssemblyNamed("Framework.DataAccess.NHibernateProvider") .BasedOn(typeof(IReadDao<>)).WithService.Base()); } } return _daoContainer; } } public static T Create<T>() where T : IDao { return DaoContainer.Resolve<T>(); } } This assembly also defines the base interface for data access IReadDao: public interface IReadDao<T> { IEnumerable<T> GetAll(); } I want to keep this assembly generic and with no references. This is my base data access assembly. Then I have the NHibernate provider's assembly, which implements the above IReadDao using NHibernate's approach. This assembly references the "Framework.DataAccess" assembly. public class NHibernateDao<T> : IReadDao<T> { public NHibernateDao() { } public virtual IEnumerable<T> GetAll() { throw new NotImplementedException(); } } At last, I have the "Company.DataAccess" assembly, which can override the default implementation of NHibernate provider and references both previously seen assemblies. public interface IProductDao : IReadDao<Product> { Product GetByName(string name); } public class ProductDao : NHibernateDao<Product>, IProductDao { public override IEnumerable<Product> GetAll() { throw new NotImplementedException("new one!"); } public Product GetByName(string name) { throw new NotImplementedException(); } } I want to be able to write... IRead<Product> dao = DaoFactory.Create<IRead<Product>>(); ... and then get the ProductDao implementation. But I can't hold inside my base data access any reference to specific assemblies! My initial idea was to read that from a xml config file. So, my question is: How can I externally configure this factory to use a specific provider as my default implementation and my client implementation?

  • Extending Enums, Overkill?

    - by CkH
    I have an object that needs to be serialized to an EDI format. For this example we'll say it's a car. A car might not be the best example b/c options change over time, but for the real object the Enums will never change. I have many Enums like the following with custom attributes applied. public enum RoofStyle { [DisplayText("Glass Top")] [StringValue("GTR")] Glass, [DisplayText("Convertible Soft Top")] [StringValue("CST")] ConvertibleSoft, [DisplayText("Hard Top")] [StringValue("HT ")] HardTop, [DisplayText("Targa Top")] [StringValue("TT ")] Targa, } The Attributes are accessed via Extension methods: public static string GetStringValue(this Enum value) { // Get the type Type type = value.GetType(); // Get fieldinfo for this type FieldInfo fieldInfo = type.GetField(value.ToString()); // Get the stringvalue attributes StringValueAttribute[] attribs = fieldInfo.GetCustomAttributes( typeof(StringValueAttribute), false) as StringValueAttribute[]; // Return the first if there was a match. return attribs.Length > 0 ? attribs[0].StringValue : null; } public static string GetDisplayText(this Enum value) { // Get the type Type type = value.GetType(); // Get fieldinfo for this type FieldInfo fieldInfo = type.GetField(value.ToString()); // Get the DisplayText attributes DisplayTextAttribute[] attribs = fieldInfo.GetCustomAttributes( typeof(DisplayTextAttribute), false) as DisplayTextAttribute[]; // Return the first if there was a match. return attribs.Length > 0 ? attribs[0].DisplayText : value.ToString(); } There is a custom EDI serializer that serializes based on the StringValue attributes like so: StringBuilder sb = new StringBuilder(); sb.Append(car.RoofStyle.GetStringValue()); sb.Append(car.TireSize.GetStringValue()); sb.Append(car.Model.GetStringValue()); ... There is another method that can get Enum Value from StringValue for Deserialization: car.RoofStyle = Enums.GetCode<RoofStyle>(EDIString.Substring(4, 3)) Defined as: public static class Enums { public static T GetCode<T>(string value) { foreach (object o in System.Enum.GetValues(typeof(T))) { if (((Enum)o).GetStringValue() == value.ToUpper()) return (T)o; } throw new ArgumentException("No code exists for type " + typeof(T).ToString() + " corresponding to value of " + value); } } And Finally, for the UI, the GetDisplayText() is used to show the user friendly text. What do you think? Overkill? Is there a better way? or Goldie Locks (just right)? Just want to get feedback before I intergrate it into my personal framework permanently. Thanks.

  • Included php file calling Javascript function

    - by Illes Peter
    Hi there! Here's the deal. I've got index.php which links to an internal JS file in it's header. index.php then includes another .php file, which outputs this: + add file. addFile() is a Javascript function defined in the external JS file. By doing this nothing happens, the included php does not "see" the JS function. Encapsulating the JS in the included PHP makes it all work. But I don't want to do it that way. Any ideas? EDIT: here's the source <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>Archie</title> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/> <link rel="stylesheet" href="/screen.css" type="text/css" media="screen"/> <script src="/lib/js/archie.js" type="text/javascript"></script> </head> <body> ... ... //included php starts here <form action="/lib/course.php" method="post"> <fieldset> <div id="addFileLocation"></div> <a href="#" onClick="addFile()">+ add file</a> <input type="hidden" id="addFileCount" value="0"/> </fieldset> </form> //ends here ... ... </body> </html> and the js: <script type="text/javascript"> //Dynamically add form fields //add file browser function addFile() { var location = document.getElementById('addFileLocation'); var num = document.getElementById('addFileCount'); var newnum = (document.getElementById('addFileCount').value -1)+ 2; num.value = newnum; var newname = 'addFile_'+newnum; var newelement = document.createElement('input'); newelement.setAttribute('name',newname); newelement.setAttribute('type','file'); location.appendChild(newelement); } </script>

  • How do I debug an ASP.NET web service in Visual Studio?

    - by Ben McCormack
    I have an ASP.NET .ASMX web service that I converted to .NET 4.0 with VS 2010 and is hosted in an IIS 7.5 (Windows 7) application pool. I have a simple html page that I use to make the AJAX request to the web service. How can I debug what's going on in the web service in Visual Studio? Because the HTML ajax request doesn't seem "tied in" to the web service, which is located on my local IIS service, I can't figure out how to debug it.

  • What am I missing in this ASP.NET XSS Security Helper class?

    - by smartcaveman
    I need a generic method for preventing XSS attacks in ASP.NET. The approach I came up with is a ValidateRequest method that evaluates the HttpRequest for any potential issues, and if issues are found, redirect the user to the same page, but in a away that is not threatening to the application. (Source code below) While I know this method will prevent most XSS attacks, I am not certain that I am adequately preventing all possible attacks while also minimizing false positives. So, what is the most effective way to adequately prevent all possible attacks, while minimizing false positives? Are there changes I should make to the helper class below, or is there an alternative approach or third party library that offers something more convincing? public static class XssSecurity { public const string PotentialXssAttackExpression = "(http(s)*(%3a|:))|(ftp(s)*(%3a|:))|(javascript)|(alert)|(((\\%3C) <)[^\n]+((\\%3E) >))"; private static readonly Regex PotentialXssAttackRegex = new Regex(PotentialXssAttackExpression, RegexOptions.IgnoreCase); public static bool IsPotentialXssAttack(this HttpRequest request) { if(request != null) { string query = request.QueryString.ToString(); if(!string.IsNullOrEmpty(query) && PotentialXssAttackRegex.IsMatch(query)) return true; if(request.HttpMethod.Equals("post", StringComparison.InvariantCultureIgnoreCase)) { string form = request.Form.ToString(); if (!string.IsNullOrEmpty(form) && PotentialXssAttackRegex.IsMatch(form)) return true; } if(request.Cookies.Count > 0) { foreach(HttpCookie cookie in request.Cookies) { if(PotentialXssAttackRegex.IsMatch(cookie.Value)) { return true; } } } } return false; } public static void ValidateRequest(this HttpContext context, string redirectToPath = null) { if(context == null || !context.Request.IsPotentialXssAttack()) return; // expire all cookies foreach(HttpCookie cookie in context.Request.Cookies) { cookie.Expires = DateTime.Now.Subtract(TimeSpan.FromDays(1)); context.Response.Cookies.Set(cookie); } // redirect to safe path bool redirected = false; if(redirectToPath != null) { try { context.Response.Redirect(redirectToPath,true); redirected = true; } catch { redirected = false; } } if (redirected) return; string safeUrl = context.Request.Url.AbsolutePath.Replace(context.Request.Url.Query, string.Empty); context.Response.Redirect(safeUrl,true); } }

  • Google Chrome extension: Use Javascript inside webkit notifications?

    I have been following the Google Chrome Extensions Developer's guide and have been able so far to create an extension with a browser action without popup that would trigger a webkit notification in HTML format. Fact is that this HTML file contains action buttons, links and javascript, but none of them seems to respond. Is this a by-design behavior or is there a way for embedding javascript/links/buttons in these webkit notifications?

    Hi, I;ve been trying to create a custom button in android using this tutorial - http://www.gersic.com/blog.php?id=56 It works well but it doesn't say how to change the font size or weighting. Any ideas? There was another question on here and the only answer was to use html styling but you can't change a font size in html without using css (or the deprecated font tag). There must be a better way of setting the pixel size of the font used on buttons?

  • java spring and ftl

    - by bobby
    I defined a modelview object named "buttonpressed" in spring controller file and I need to access that modelview object in ftl(freemarker) file which is being returned as a view from a controller like abcd.java The abcd.java controller code is as below if (questionAnswer.getAnswerId() == 1045) { modelAndView.addObject("buttonPressed","You have been added in mailing list"); modelAndView.setViewName("enterCode_nextSteps"); } else { modelAndView.addObject("buttonPressed","Not added in the mailing list"); modelAndView.setViewName("enterCode_nextSteps"); } the below ajax function is working fine currently but I am not sure how to access this object called "buttonpressed" in this ajax function. I have written like the way mentioned below but when i am clicking the submit link its not calling "partner.do" and also throwing error saying #buttonPressed is undefind (but in the script below its working fine and calling "partner.do" and even posting data) So is that problem coming from javsscript code i mean due to incorrect use of "buttonPressed" or might be problem from spring controller abcd.java file. <div class="partnerOptInBox"> <div id="optInContent"> <form name="partnerOptIn"> <h4>Want the Latest</h4> <p class="pad10Top">${partnerOpt.translation}</p> <div class="pad10Top"> <input type="radio" name="questionAnswer['${partnerOpt.questionId}']" value="${partnerOpt.getAnswers()[0].answerId}" class="radioButton" /> <label for="questionAnswer['${partnerOpt.questionId}']" class="formLabel pad20Right">Yes</label> <input type="radio" name="questionAnswer['${partnerOpt.questionId}']" class="radioButton" value="${partnerOpt.getAnswers()[1].answerId}" /> <label for="questionAnswer['${partnerOpt.questionId}']" class="formLabel">No</label> </div> <div id="optInError" class="formError" style="display:none;">Oops... your request did not go through, please try again.</div> <div class="pad15Top"> <a href="javascript:submitOptIn();"><img src="images/theme/btn_opt_in_submit.gif"/></a> </div> </form> <script type="text/javascript"> function submitOptIn() { $('optInError').hide(); dataString = $('#partnerOptIn').serialize(); $.ajax({ data: dataString, url: "partnerOpt.do", timeout: 30000, type: "POST", success: function(html){ var newHtml = "<h4>Thank you</h4><p>We appreciate your time to respond to our request.</p>"; $('#optInContent').html(newHtml); }, */trying this code for sucess is throwing me an error /* <!-- buttonpressed function--> success: function(html){ $('#optInContent').html(${buttonPressed}); }, <!-- buttonpressed function--> error: function(){ $('#optInError').show(); } }); } </script>

  • What's a clean way to break up a DataTable into chunks of a fixed size with Linq?

    - by Michael Haren
    Update: Here's a similar question Suppose I have a DataTable with a few thousand DataRows in it. I'd like to break up the table into chunks of smaller rows for processing. I thought C#3's improved ability to work with data might help. This is the skeleton I have so far: DataTable Table = GetTonsOfData(); // Chunks should be any IEnumerable<Chunk> type var Chunks = ChunkifyTableIntoSmallerChunksSomehow; // ** help here! ** foreach(var Chunk in Chunks) { // Chunk should be any IEnumerable<DataRow> type ProcessChunk(Chunk); } Any suggestions on what should replace ChunkifyTableIntoSmallerChunksSomehow? I'm really interested in how someone would do this with access C#3 tools. If attempting to apply these tools is inappropriate, please explain! Update 3 (revised chunking as I really want tables, not ienumerables; going with an extension method--thanks Jacob): Final implementation: Extension method to handle the chunking: public static class HarenExtensions { public static IEnumerable<DataTable> Chunkify(this DataTable table, int chunkSize) { for (int i = 0; i < table.Rows.Count; i += chunkSize) { DataTable Chunk = table.Clone(); foreach (DataRow Row in table.Select().Skip(i).Take(chunkSize)) { Chunk.ImportRow(Row); } yield return Chunk; } } } Example consumer of that extension method, with sample output from an ad hoc test: class Program { static void Main(string[] args) { DataTable Table = GetTonsOfData(); foreach (DataTable Chunk in Table.Chunkify(100)) { Console.WriteLine("{0} - {1}", Chunk.Rows[0][0], Chunk.Rows[Chunk.Rows.Count - 1][0]); } Console.ReadLine(); } static DataTable GetTonsOfData() { DataTable Table = new DataTable(); Table.Columns.Add(new DataColumn()); for (int i = 0; i < 1000; i++) { DataRow Row = Table.NewRow(); Row[0] = i; Table.Rows.Add(Row); } return Table; } }

  • How to create constant NSString by concatenating strings in Obj-C ?

    - by eric-morand
    Hi guys, I'm trying to instanciate a constant NSString by concatanating other NSString instances. Here is what I'm doing in my implementation file : static NSString *const MY_CONST = @"TEST"; static NSString *const MY_CONCATENATE_CONST = [NSString stringWithFormat:@"STRING %@", MY_CONST]; It leads to the following compilation error : Initializer element is not constant I suppose this is because stringWithFormat doesn't return a constant NSString, but since there is no other way to concatenate strings in Obj-C, what am I supposed to do ? Thanks for your help, Eric.

  • .net Email Template engine...

    - by alex
    I'm looking to create emails, mainly HTML, based on templates - I'd really like to do something like: Set up my template, as an HTML (or similar) file Include tags, that are then replaced with specific data (kind of like mail-merge....) I've seen this: http://www.bitethebullet.co.uk/EmailTemplateFramework/tabid/58/Default.aspx From searching on stack overflow, i understand nVelocity might be another option? But i can't find any examples to do what i want to do... Any other suggestions?

  • Constructor or Explicit cast

    - by Felan
    In working with Linq to Sql I create a seperate class to ferry data to a web page. To simplify creating these ferry objects I either use a specialized constructor or an explicit conversion operator. I have two questions. First which approach is better from a readibility perspective? Second while the clr code that is generated appeared to be the same to me, are there situations where one would be treated different than the other by the compiler (in lambda's or such). Example code (DatabaseFoo uses specialized constructor and BusinessFoo uses explicit operator): public class DatabaseFoo { private static int idCounter; // just to help with generating data public int Id { get; set; } public string Name { get; set; } public DatabaseFoo() { Id = idCounter++; Name = string.Format("Test{0}", Id); } public DatabaseFoo(BusinessFoo foo) { this.Id = foo.Id; this.Name = foo.Name; } } public class BusinessFoo { public int Id { get; set; } public string Name { get; set; } public static explicit operator BusinessFoo(DatabaseFoo foo) { return FromDatabaseFoo(foo); } public static BusinessFoo FromDatabaseFoo(DatabaseFoo foo) { return new BusinessFoo {Id = foo.Id, Name = foo.Name}; } } public class Program { static void Main(string[] args) { Console.WriteLine("Creating the initial list of DatabaseFoo"); IEnumerable<DatabaseFoo> dafoos = new List<DatabaseFoo>() { new DatabaseFoo(), new DatabaseFoo(), new DatabaseFoo(), new DatabaseFoo(), new DatabaseFoo(), new DatabaseFoo()}; foreach(DatabaseFoo dafoo in dafoos) Console.WriteLine(string.Format("{0}\t{1}", dafoo.Id, dafoo.Name)); Console.WriteLine("Casting the list of DatabaseFoo to a list of BusinessFoo"); IEnumerable<BusinessFoo> bufoos = from x in dafoos select (BusinessFoo) x; foreach (BusinessFoo bufoo in bufoos) Console.WriteLine(string.Format("{0}\t{1}", bufoo.Id, bufoo.Name)); Console.WriteLine("Creating a new list of DatabaseFoo by calling the constructor taking BusinessFoo"); IEnumerable<DatabaseFoo> fufoos = from x in bufoos select new DatabaseFoo(x); foreach(DatabaseFoo fufoo in fufoos) Console.WriteLine(string.Format("{0}\t{1}", fufoo.Id, fufoo.Name)); } }
