  • jQuery Tablesorter - column not sorting alphabetically

    - by McGirl
    I'm not sure what's going wrong here. This is the page: http://www.utexas.edu/ssw/cswr/projects/project-list/ The first column sorts, but it isn't returning data in the correct order (alphabetical). The table itself is being generated by a custom PHP function that pulls info from a WordPress database. I thought that might be the issue, but as you can see the fourth column (End Date) sorts correctly. I also thought it might be the links in the first column that were messing things up, but adding the text-extraction code from this page broke the sorting altogether. This is the jQuery code I'm current using to call Tablesorter: <script type="text/javascript" id="js"> jQuery(document).ready(function($) { $(document).ready(function() { // call the tablesorter plugin, the magic happens in the markup $("#projectTable").tablesorter({ // pass the headers argument and assing a object //debug: true, //sortList: [[0,0]], headers: { 0: { // set the column to sort as text sorter: 'text', }, // assign the secound column (we start counting zero) 1: { // disable it by setting the property sorter to false sorter: false, }, // assign the third column (we start counting zero) 2: { // disable it by setting the property sorter to false sorter: false }, 3: { sorter:'digit' } } }); // Works only with plugin modification $("#projectTable").bind("sortStart",function(e) { if( $(e.target).hasClass('header') ) { $("#overlay").show(); } }).bind("sortEnd",function(e) { if( $(e.target).hasClass('header') ) { $("#overlay").hide(); } }); }); }); </script> Thanks for your help!

  • Dynamically populated NSPopUpButtonCell menu in an NSOutlineView

    - by Mo
    I’m working with an NSOutlineView which has two columns. My dataSource supplies the outline view with a tree of items of a custom class which represents file types (that is, you initialise it with a UTI). The first column is the display name of the file type (e.g., “Source code”, “Interface Builder NIB document”, etc.). The second column is an NSPopUpButtonCell which is supposed to allow the user to pick a handler for the given document type (think of Xcode’s “File Types” preference pane, and you’re pretty much there). I can generate an NSMenu for a given item in the tree, populated with options based upon the Launch Services database entries for the UTI, complete with the relevant application icon and and so on. In fact, the menu itself works wonderfully, populated by way of NSPopUpButtonCellWillPopUpNotification. The problem is, try as I might, the cell when the menu isn’t popped up always contains precisely one of two things: either an empty string, or the default text for the cell, the former if the result of -handlerName on the item (the attribute assigned to the column) is non-nil, the latter otherwise. Moreover, I’m manually calling -selectItem: on the NSPopUpButtonCell instance, which just seems Wrong. In contrast, the left-hand column, which is just an NSTextFieldCell, everything just works (although granted, all it’s got to do is read the value from the item and present it). (Disclaimer: I’m fairly new at Cocoa UI stuff; I know Objective-C, and lots of other programming languages, but I’ve not a huge amount of experience of building Mac OS X UIs, so be gentle).

  • ASP.NET output caching - dynamically update dependencies

    - by ColinE
    Hi All, I have an ASP.NET application which requires output caching. I need to invalidate the cached items when the data returned from a web service changes, so a simple duration is not good enough. I have been doing a bit of reading about cache dependencies and think I have the right idea. It looks like I will need to create a cache dependency to my web service. To associate the page output with this dependency I think I should use the following method: Response.AddCacheItemDependency(cacheKey); The thing I am struggling with is what I should add to the cache? The dependency my page has is to a single value returned by the web service. My current thinking is that I should create a Custom Cache Dependency via subclassing CacheDependency, and store the current value in the cache. I can then use Response.AddCacheItemDependency to form the dependency. I can then periodically check the value and for a NotifyDependencyChange in order to invalidate my cached HTTP response. The problem is, I need to ensure that the cache is flushed immediately, so a periodic check is not good enough. How can I ensure that my dependant object in the cache which represents the value returned by the web service is re-evaluated before the HTTP response is fetched from the cache? Regards, Colin E.

  • drupal form textfield #default_value not working

    - by alvin.ng
    I am working on a custom module with multi-page form on drupal 6. I found that #default_value is not working when my '#type' = 'textfield'. However, when '#type'='textarea', it displays correctly with the '#default_value' specified. Basically, I wrote a FormFactory to return different form definition ($form) based on the post parameter received. Initially, it returns the display of directories list, user then selects from radio buttos until a specific directory contains a xml file, it will become edit form. The edit form will have text fields display the data (#default_value) inside the xml file, however the type 'textarea' works here rather than 'textfield'. How can I make my '#default_value' work in this case? Below is the non-working field definition: $form['pageset']['newsTitle'] = array( '#type' => 'textfield', '#title' => 'News Title', '#default_value' => "{$element->newsTitle}", '#rows' => 1, '#required' => TRUE, ); Then I changed it to textarea as shown below to make it work: $form['pageset']['newsTitle'] = array( '#type' => 'textarea', '#title' => 'News Title', '#default_value' => "{$element->newsTitle}", '#rows' => 1, '#required' => TRUE, );

  • PhpBB3: adding background to specific php generated text input without affecting the other text inputs

    - by user1780055
    I have created a custom PhpBB3 style and desperately since a few hours tried to add a background image to a specific comment text area. With firebug I checked if the comment text area had a class and it does, so I tried some css variations and finally tried: sn-inputComment { background: url("{T_THEME_PATH}/images/pencil.png") repeat-x left top #FFFFFF;} { I also tried to find and manipulate the php generated text area but no success. Non of my methods worked. I will provide you all with a tinylink url to my forum with a test user and password access. User: test Password: 123456 url: http://tinyurl.com/9yqpxdb Now when you are logged in you should be redirected to the correct url and you will see a a few text boxes with "Write a comment...". I would be very happy if you could tell me what I did wrong, why im not able to add a background to the text input without having my search boxes and "what is on your mind box" affected. I appreciate your time and hope that this can be somehow solved. Sincerely, Daniel

  • WPF, notify a child in the element tree about an event in a parent

    - by jester
    I am developing a WPF app and I want an event in a parent to be notified to several of its children in the element tree, so that each of them can take an action accordingly. I know that a custom RoutedEvent can be used to signal in the other direction from a child to one of its ancestors by bubbling the event upwards, so that any of the ancestor elements can handle the event. What I want is the children to be notified about an event in the parent and they handle them appropriately. What is the best strategy to achieve this? EDIT: Clarifying the comments : Say I have a parent UserControl. It has a TabControl and its contents are several nested child UserControls. Now consider a scenario where I want the TabControl.SelectionChanged() event to cause some changes in each of the child UserControl. How to achieve this? (The contents of each tab is a UserControl which themselves may contain another few levels of children UserControls. I want the UserControl in the bottom level to know about the SelectionChanged() event and respond accordingly).

  • Mac vs. Windows Browser Font Height Rendering Issue

    - by cdmckay
    I'm using a custom font and the @font-face tag. In Windows, everything looks great, regardless of whether it's Firefox, Chrome, or IE. On Mac, it's a different story. For some reason, the Mac font renderer thinks the font is a lot shorter than it is. For example, consider this test code (live example here): <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> <title>Webble</title> <style type="text/css"> @font-face { font-family: "Bubbleboy 2"; src: url("bubbleboy-2.ttf") format('truetype'); } body { font-family: "Bubbleboy 2"; font-size: 30px; } div { background-color: maroon; color: yellow; height: 100px; line-height: 100px; } </style> </head> <body> <div>The quick brown fox jumped over the lazy dog.</div> </body> </html> Open it on Windows Firefox and on Mac Firefox. Use your mouse to select it. On Windows, you'll notice it fully selects the font. On Mac, it only selects about half the font. If you look at what it is selecting, you'll see that that part has been centered, instead of the full height of the font. Is there anyway to fix this rather large discrepancy?

  • spring - constructor injection and overriding parent definition of nested bean

    - by mdma
    I've read the Spring 3 reference on inheriting bean definitions, but I'm confused about what is possible and not possible. For example, a bean that takes a collaborator bean, configured with the value 12 <bean name="beanService12" class="SomeSevice"> <constructor-arg index="0"> <bean name="beanBaseNested" class="SomeCollaborator"> <constructor-arg index="0" value="12"/> </bean> </constructor-arg> </bean> I'd then like to be able to create similar beans, with slightly different configured collaborators. Can I do something like <bean name="beanService13" parent="beanService12"> <constructor-arg index="0"> <bean> <constructor-arg index="0" value="13"/> </bean> </constructor> </bean> I'm not sure this is possible and, if it were, it feels a bit clunky. Is there a nicer way to override small parts of a large nested bean definition? It seems the child bean has to know quite a lot about the parent, e.g. constructor index. I'd prefer not to change the structure - the parent beans use collaborators to perform their function, but I can add properties and use property injection if that helps. This is a repeated pattern, would creating a custom schema help? Thanks for any advice!

  • How to debug into my apache module built using a Makefile?

    - by AJ
    Firstly, I come from Windows-VisualStudio-C++ background. Now I am developing in a Ubuntu environment. With the help of a Makefile, I built a mymodule.so and copied it to the modules folder within apache. Now, it appears that the module is working fine. But I would like to debug into this module to understand it better. So, first, is there any way I can get something similar to the Visual Studio debugger type of feel while debugging this module? Now, i read that i can use gdb to debug into apache modules, can somebody tell me in detail how this is done or point me to some resource that does it. Ideally, i would like to single step and stuff. I am trying Code::Blocks IDE which has some debugging support. Using the IDE and custom make file, I build the module. Copied it to module location, but how do i debug. How do i hook to the apache process. Should I use Attach to Process. I tried that with the pid of httpd, but with no success. Also, while building is there some flag that i should set so that the .so file is debuggable? I am pretty basic with Linux because i come from windows programming background. Kindly suggest how I go about this. Thanks in advance, Arjun

  • Is there a way to automaticly call all versions of an inherited method?

    - by Eric
    I'm writing a plug-in for a 3D modeling program. I have a custom class that wraps instances of elements in the 3D model, and in turn derives it's properties from the element it wraps. When the element in the model changes I want my class(es) to update their properties based on the new geometry. In the simplified example below. I have classes AbsCurveBasd, Extrusion, and Shell which are all derived from one another. Each of these classes implement a RefreshFromBaseShape() method which updates specific properties based on the current baseShape the class is wrapping. I can call base.RefreshFromBaseShape() in each implementation of RefreshFromBaseShape() to ensure that all the properties are updated. But I'm wondering if there is a better way where I don't have to remember to do this in every implementation of RefershFromBaseShape()? For example because AbsCurveBased does not have a parameterless constructor the code wont even compile unless the constructors call the base class constructors. public abstract class AbsCurveBased { internal Curve baseShape; double Area{get;set;} public AbsCurveBased(Curve baseShape) { this.baseShape = baseShape; RefreshFromBaseShape(); } public virtual void RefreshFromBaseShape() { //sets the Area property from the baseShape } } public class Extrusion : AbsCurveBased { double Volume{get;set;} double Height{get;set;} public Extrusion(Curve baseShape):base(baseShape) { this.baseShape = baseShape; RefreshFromBaseShape(); } public override void RefreshFromBaseShape() { base.RefreshFromBaseShape(); //sets the Volume property based on the area and the height } } public class Shell : Extrusion { double ShellVolume{get;set;} double ShellThickness{get;set;} public Shell(Curve baseShape): base(baseShape) { this.baseShape = baseShape; RefreshFromBaseShape(); } public void RefreshFromBaseShape() { base.RefreshFromBaseShape(); //sets this Shell Volume from the Extrusion properties and ShellThickness property } }

  • Connecting an overloaded PyQT signal using new-style syntax

    - by Claudio
    I am designing a custom widget which is basically a QGroupBox holding a configurable number of QCheckBox buttons, where each one of them should control a particular bit in a bitmask represented by a QBitArray. In order to do that, I added the QCheckBox instances to a QButtonGroup, with each button given an integer ID: def populate(self, num_bits, parent = None): """ Adds check boxes to the GroupBox according to the bitmask size """ self.bitArray.resize(num_bits) layout = QHBoxLayout() for i in range(num_bits): cb = QCheckBox() cb.setText(QString.number(i)) self.buttonGroup.addButton(cb, i) layout.addWidget(cb) self.setLayout(layout) Then, each time a user would click on a checkbox contained in self.buttonGroup, I'd like self.bitArray to be notified so I can set/unset the corresponding bit in the array. For that I intended to connect QButtonGroup's buttonClicked(int) signal to QBitArray's toggleBit(int) method and, to be as pythonic as possible, I wanted to use new-style signals syntax, so I tried this: self.buttonGroup.buttonClicked.connect(self.bitArray.toggleBit) The problem is that buttonClicked is an overloaded signal, so there is also the buttonClicked(QAbstractButton*) signature. In fact, when the program is executing I get this error when I click a check box: The debugged program raised the exception unhandled TypeError "QBitArray.toggleBit(int): argument 1 has unexpected type 'QCheckBox'" which clearly shows the toggleBit method received the buttonClicked(QAbstractButton*) signal instead of the buttonClicked(int) one. So, the question is, how can we specify, using new-style syntax, that self.buttonGroup emits the buttonClicked(int) signal instead of the default overload - buttonClicked(QAbstractButton*)?

  • jQuery: preventDefault() not working on input/click events?

    - by Jason
    I want to disable the default contextMenu when a user right-clicks on an input field so that I can show a custom contextMenu. Generally speaking, its pretty easy to disable the right-click menu by doing something like: $([whatever]).bind("click", function(e) { e.preventDefault(); }); And in fact, I can do this on just about every element EXCEPT for input fields in FF - anyone know why or could point me towards some documentation? Here is the relevant code I am working with, thanks guys. HTML: <script type="text/javascript"> var r = new RightClickTool(); </script> <div id="main"> <input type="text" class="listen rightClick" value="0" /> </div> JS: function RightClickTool(){ var _this = this; var _items = ".rightClick"; $(document).ready(function() { _this.init(); }); this.init = function() { _this.setListeners(); } this.setListeners = function() { $(_items).click(function(e) { var webKit = !$.browser.msie && e.button == 0; var ie = $.browser.msie && e.button == 1; if(webKit||ie) { // Left mouse...do something() } else if(e.button == 2) { e.preventDefault(); // Right mouse...do something else(); } }); } } // Ends Class

  • Visual Studio opening .xml files in Notepad

    - by Portman
    So I'm happily working on a project making heavy use of custom .xml configuration files this morning. All of a sudden, whenever I double-click an .xml file in Solution Explorer, it opens in Notepad instead of within Visual Studio. Thinking that it was the Windows file associations, I right-clicked on a file in Explorer, selected Open With Choose Defaults, and selected Visual Studio 2008. But the problem remains -- now when I open a file from Explorer, Visual Studio Opens, then it opens Notepad. Needless to say, this is very frustrating, and Google is not much help. Has anyone else ever had this problem, and what did you do about it? Notes: This only happens for .xml files. Other text files (.config, .txt) open within Visual Studio just fine. This has nothing to do with Windows file associations, as Windows open up VS2008 just as it should. This is some crazy problem internal to Visual Studio. I've also tried Tools Options General Restore File Associations. No luck. Nothing present in Tools Options Text Editor File Extension This is what my "Open With" menu looks like for .xml files. As you can see, "XML Editor" is set to the default.

  • Different ways to use properties file in j2ee app

    - by Omnipresent
    I have a j2ee app using Struts2. I have a gloabl properties file which is declared in struts.properties which resides in WEB-INF/classes. It has the following setting: struts.custom.i18n.resources=mypropertyfile mypropertyfile also resides in WEB-INF/classes Say for example it contains the following: pdf.test.title=PDF Test then on jsp I use the following to make use of the property file <s:text name="pdf.test.title"/> This setup was working on Sun App server 8.2 but is not working on GlassFish App Server (I see pdf.test.title on the browser rather than PDF Test). I do not have access to GlassFish App server to try and tweak the setting to make it work. So I want to make changes to the code and see if that will help. My question is: What are some other ways to use properties file in a J2EE app? (using Struts2 or not). I'm also open to ways suggested to make changes on glassfish to make this work? Build/version #'s GlassFish = 9.1_02 (build b04-fcs) Struts2 = 2.0.6 JRE6

  • PHP: tips/resources/patterns for learning to implement a basic ORM

    - by BoltClock
    I've seen various MVC frameworks as well as standalone ORM frameworks for PHP, as well as other ORM questions here; however, most of the questions ask for existing frameworks to get started with, which is not what I'm looking for. (I have also read this SO question but I'm not sure what to make of it, and the answers are vague.) Instead, I figured I'd learn best by getting my hands dirty and actually writing my own ORM, even a simple one. Except I don't really know how to get started, especially since the code I see in other ORMs is so complicated. With my PHP 5.2.x (this is important) MVC framework I have a basic custom database abstraction layer, that has: Very simple methods like connect($host, $user, $pass, $base), query($sql, $binds), etc Subclasses for each DBMS that it supports A class (and respective subclasses) to represent SQL result sets But does not have: Active Record functionality, which I assume is an ORM thing (correct me if I'm wrong) I've read up a little about ORM, and from my understanding they provide a means to further abstract data models from the database itself by representing data as nothing more than PHP-based classes/objects; again, correct me if I am wrong or have missed out in any way. Still, I'd like some simple tips from anyone else who's dabbled more or less with ORM frameworks. Is there anything else I need to take note of, simple example code for me to refer to, or resources I can read? Thanks a lot in advance!

  • Python - Why use anything other than uuid4() for unique strings?

    - by orokusaki
    I see quit a few implementations of unique string generation for things like uploaded image names, session IDs, et al, and many of them employ the usage of hashes like SHA1, or others. I'm not questioning the legitimacy of using custom methods like this, but rather just the reason. If I want a unique string, I just say this: >>> import uuid >>> uuid.uuid4() 07033084-5cfd-4812-90a4-e4d24ffb6e3d And I'm done with it. I wasn't very trusting before I read up on uuid, so I did this: >>> import uuid >>> s = set() >>> for i in range(5000000): # That's 5 million! >>> s.add(uuid.uuid4()) ... ... >>> len(s) 5000000 Not one repeater (I didn't expect one considering the odds are like 1.108e+50, but it's comforting to see it in action). You could even half the odds by just making your string by combining 2 uuid4()s. So, with that said, why do people spend time on random() and other stuff for unique strings, etc? Is there an important security issue or other regarding uuid?

    Currently I have a knockout binding that stripes rows in a list which works fine ko.bindingHandlers.stripe = { update: function (element, valueAccessor, allBindingsAccessor) { var value = ko.utils.unwrapObservable(valueAccessor()); //creates the dependency var allBindings = allBindingsAccessor(); var even = allBindings.evenClass; var odd = allBindings.oddClass; //update odd rows $(element).children(":nth-child(odd)").addClass(odd).removeClass(even); //update even rows $(element).children(":nth-child(even)").addClass(even).removeClass(odd); ; } } Triggered from <button data-bind="click: addWidget" style="display:none">Add Item</button> The problem I have is when reloading data from the server , I call addWidget() manually in the view model the stripe binding handler is not applied - all rows appear as same color, if I click the html button then the binding happens and stripes appear var ViewModel = function() { self.addWidget(); }); Is it possible to reapply this custom binding manually in js? Thanks Edit: The stripe binding gets applied like so <div data-bind="foreach: widgets, stripe: widgets, evenClass: 'light', oddClass: 'dark'">

  • CallbackValidator called with empty string

    - by Paolo Tedesco
    I am writing a custom configuration section, and I would like to validate a configuration property with a callback, like in this example: using System; using System.Configuration; class CustomSection : ConfigurationSection { [ConfigurationProperty("stringValue", IsRequired = false)] [CallbackValidator(Type = typeof(CustomSection), CallbackMethodName = "ValidateString")] public string StringValue { get { return (string)this["stringValue"]; } set { this["stringValue"] = value; } } public static void ValidateString(object value) { if (string.IsNullOrEmpty((string)value)) { throw new ArgumentException("string must not be empty."); } } } class Program { static void Main(string[] args) { CustomSection cfg = (CustomSection)ConfigurationManager.GetSection("customSection"); Console.WriteLine(cfg.StringValue); } } And my App.config file looks like this: <?xml version="1.0" encoding="utf-8" ?> <configuration> <configSections> <section name="customSection" type="CustomSection, config-section"/> </configSections> <customSection stringValue="lorem ipsum"/> </configuration> My problem is that when the ValidateString function is called, the value parameter is always an empty string, and therefore the validation fails. If i just remove the validator, the string value is correctly initialized to the value in the configuration file. What am I missing?

  • using mod-rewrite to redirect requests for jquery.js to GoogleAPI cache

    - by Aditya Advani
    Hi All, Our Linux server with Apache 2.x, Plesk 8.x hosts a number of e-commerce websites. To take advantage of browser caching we would like to use Google's provided copy of jquery.js. Hence in the vhost.conf file of each we can use the following RewriteRule RewriteCond %{REQUEST_FILENAME} jquery.min.js [nc] RewriteRule . http://ajax.googleapis.com/ajax/libs/jquery/1.4/jquery.min.js [L] And in vhost_ssl.conf RewriteCond %{REQUEST_FILENAME} jquery.min.js [nc] RewriteRule . https://ajax.googleapis.com/ajax/libs/jquery/1.4/jquery.min.js [L] OK now these rules work fine in the individual vhost.conf files of each domain. However we host over 200 domains, I would like for them to work but cannot seem to get them to work globally in the httpd.conf file. Challenges are the following: Get the rewriterule to work in httpd.conf Detect if HTTPS is on, and if it is and the is is a secure page, rewrite to ... Each individual domain will still have it's own custom mod-rewrite rules. Which rules take precedence - global or per-domain? Do they combine? Is it ok if I have the "RewriteEngine On" directive in the global httpd.conf and then again in the vhost.conf? Please let me know what your guys' suggestions are. Desperate for a solution to this problem.

  • .NET 4.0 Implementing OutputCacheProvider

    - by azamsharp
    I am checking out the OutputCacheProvider in ASP.NET 4.0 and using it to store my output cache into the MongoDb database. I am not able to understand the purpose of Add method which is one of the override methods for OutputCacheProvider. The Add method is invoked when you have VaryByParam set to something. So, if I have VaryByParam = "id" then the Add method will be invoked. But after the Add the Set is also invoked and I can insert into the MongoDb database inside the Set method. public override void Set(string key, object entry, DateTime utcExpiry) { // if there is something in the query and use the path and query to generate the key var url = HttpContext.Current.Request.Url; if (!String.IsNullOrEmpty(url.Query)) { key = url.PathAndQuery; } Debug.WriteLine("Set(" + key + "," + entry + "," + utcExpiry + ")"); _service.Set(new CacheItem() { Key = MD5(key), Item = entry, Expires = utcExpiry }); } Inside the Set method I use the PathAndQuery to get the params of the QueryString and then do a MD5 on the key and save it into the MongoDb database. It seems like the Add method will be useful if I am doing something like VaryByParam = "custom" or something. Can anyone shed some light on the Add method of OutputCacheProvider?

  • Accessing the stringValue from NSTextFields on different NIBs

    - by Kyle Zaragoza
    I'm having an extremely difficult time trying to access information from an object (e.g. an NSTextField) that is located on a NIB other than my "MainMenu.nib". My current setup: I have a MainMenu.xib that contains only a toolbar at the top and an NSView. I have four other .xib files containing custom NSViews and each of their File Owner's are assigned to a NSViewController subclass which I have created for each. My MainMenu.xib contains an object that is set to my WindowController subclass that takes care of swapping the fours views into the NSView on my MainMenu.xib. All of this works fantastic. Where I have a problem: I have another class that acts as the brains to my application which sends and receives data from an online server, all of the methods I have created rely on inputs from the user that are located on the individual .xibs that swap into my MainMenu.xib's NSview. Unfortunately I have no idea on how to grab the information from the NSTextFields, textViews, etc. that are located on my individual .xib files. What I've tried: I have tried setting the File Owner's of the four individual .xibs to my "brains" class and connecting outlets defined in my "brains".h, but when I call [textField stringValue] I receive a NULL response. I'm thinking this is because I'm creating multiple instances of my "brains" class but not totally sure. Any help on accessing information from textFields from other nibs would be a great benefit, thanks in advance.

  • Customize a WCF RIA Services EndpointRSS Feed

    - by Andrew Garrison
    Is it possible to customize the parameters of a WCF RIA Services endpoint? Specifically, I would like to create a custom binding for the endpoint and increase the maxReceivedMessageSize to allow sending the contents of a file that is a few megabytes in size. I've tried meddling in the web.config, but I'm getting the following error: [InvalidOperationException]: The contract name MyNamespace.MyService could not be found in the list of contracts implemented by the service MyNamespace.MyService web.config <system.serviceModel> <bindings> <customBinding> <binding name="CustomBinaryHttpBinding"> <binaryMessageEncoding /> <httpTransport maxReceivedMessageSize="2147483647" maxBufferSize="2147483647" /> </binding> </customBinding> </bindings> <services> <service name="MyNamespace.MyService"> <endpoint address="" binding="wsHttpBinding" contract="MyNamespace.MyService" /> <endpoint address="/binary" binding="customBinding" bindingConfiguration="CustomBinaryHttpBinding" contract="MyNamespace.MyService" /> </service> </services> <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" /> </system.serviceModel>
