  • JavaScript source file not loading in IE8 Popup

    - by dkris
    I have an issue where the JavaScript source file is loading in popup for IE6, Chrome, Firefox, Safari and Opera. But the same source file is not loading up in IE8. As a result of this the HTML is not being replaced in the Popup and I am getting an error in IE8 popup saying tinyMCE is not defined I have referred to http://stackoverflow.com/questions/2949234/formatting-this-javascript-line and solved issue on all browsers except IE8. The JavaScript function is as follows: function openSupportPage() { var features="width=700,height=400,status=yes,toolbar=no,menubar=no,location=no,scrollbars=yes"; var winId=window.open('','',features); winId.document.open(); winId.document.write('<html><head><title>' + document.title + '</title><link rel="stylesheet" href="../css/default.css" type="text/css">\n'); var winDoc = winId.document; var sEl = winDoc.createElement("script"); sEl.src = "../js/tiny_mce/tiny_mce.js";/*TinyMCE source file*/ sEl.type="text/javascript"; winDoc.getElementsByTagName("head")[0].appendChild(sEl); winId.document.write('<script type="text/javascript">\n'); winId.document.write('function inittextarea() {\n'); winId.document.write('tinyMCE.init({ \n'); winId.document.write('elements : "content",\n'); winId.document.write('theme : "advanced",\n'); winId.document.write('readonly : true,\n'); winId.document.write('mode : "exact",\n'); winId.document.write('theme : "advanced",\n'); winId.document.write('readonly : true,\n'); winId.document.write('setup : function(ed) {\n'); winId.document.write('ed.onInit.add(function() {\n'); winId.document.write('tinyMCE.activeEditor.execCommand("mceToggleVisualAid");\n'); winId.document.write('});\n'); winId.document.write('}\n'); winId.document.write('});}</script>\n'); window.setTimeout(function () {/*using setTimeout to wait for the JS source file to load*/ winId.document.write('</head><body onload="inittextarea()">\n'); winId.document.write(' \n'); var hiddenFrameHTML = document.getElementById("HiddenFrame").innerHTML; hiddenFrameHTML = hiddenFrameHTML.replace(/&amp;/gi, "&"); hiddenFrameHTML = hiddenFrameHTML.replace(/&lt;/gi, "<"); hiddenFrameHTML = hiddenFrameHTML.replace(/&gt;/gi, ">"); winId.document.write(hiddenFrameHTML); winId.document.write('<textarea id="content" rows="10" style="width:100%">\n'); winId.document.write(document.getElementById(top.document.forms[0].id + ":supportStuff").innerHTML); winId.document.write('</textArea>\n'); var hiddenFrameHTML2 = document.getElementById("HiddenFrame2").innerHTML; hiddenFrameHTML2 = hiddenFrameHTML2.replace(/&amp;/gi, "&"); hiddenFrameHTML2 = hiddenFrameHTML2.replace(/&lt;/gi, "<"); hiddenFrameHTML2 = hiddenFrameHTML2.replace(/&gt;/gi, ">"); winId.document.write(hiddenFrameHTML2); winId.document.write('</body></html>\n'); winId.document.close(); }, 300); } Additional Information: Screen shot of the page Rendered HTML Original JSPF please help me with this one.

  • CSS/JavaScript/hacking: Detect :visited styling on a link *without* checking it directly OR do it fa

    - by Sai Emrys
    This is for research purposes on http://cssfingerprint.com Consider the following code: <style> div.csshistory a { display: none; color: #00ff00;} div.csshistory a:visited { display: inline; color: #ff0000;} </style> <div id="batch" class="csshistory"> <a id="1" href="http://foo.com">anything you want here</a> <a id="2" href="http://bar.com">anything you want here</a> [etc * ~2000] </div> My goal is to detect whether foo has been rendered using the :visited styling. I want to detect whether foo.com is visited without directly looking at $('1').getComputedStyle (or in Internet Explorer, currentStyle), or any other direct method on that element. The purpose of this is to get around a potential browser restriction that would prevent direct inspection of the style of visited links. For instance, maybe you can put a sub-element in the <a> tag, or check the styling of the text directly; etc. Any method that does not directly or indierctly rely on $('1').anything is acceptable. Doing something clever with the child or parent is probably necessary. Note that for the purposes of this point only, the scenario is that the browser will lie to JavaScript about all properties of the <a> element (but not others), and that it will only render color: in :visited. Therefore, methods that rely on e.g. text size or background-image will not meet this requirement. I want to improve the speed of my current scraping methods. The majority of time (at least with the jQuery method in Firefox) is spent on document.body.appendChild(batch), so finding a way to improve that call would probably most effective. See http://cssfingerprint.com/about and http://cssfingerprint.com/results for current speed test results. The methods I am currently using can be seen at http://github.com/saizai/cssfingerprint/blob/master/public/javascripts/history_scrape.js To summarize for tl;dr, they are: set color or display on :visited per above, and check each one directly w/ getComputedStyle put the ID of the link (plus a space) inside the <a> tag, and using jQuery's :visible selector, extract only the visible text (= the visited link IDs) FWIW, I'm a white hat, and I'm doing this in consultation with the EFF and some other fairly well known security researchers. If you contribute a new method or speedup, you'll get thanked at http://cssfingerprint.com/about (if you want to be :-P), and potentially in a future published paper. ETA: The bounty will be rewarded only for suggestions that can, on Firefox, avoid the hypothetical restriction described in point 1 above, or perform at least 10% faster, on any browser for which I have sufficient current data, than my best performing methods listed in the graph at http://cssfingerprint.com/about In case more than one suggestion fits either criterion, the one that does best wins.

  • IE8 Crashes Strangely on JavaScript Popup

    - by dkris
    Hi, I am facing a strange issue after the popup is created onclick. The popup opens up but hangs immediately on IE8 (works fine on all the other browsers including IE6). But on adding the alertbox as show in the JavaScript code, the popup works fine. I am using **https** and not **http** and i feel popup is not able to load the JS file because of SSL. Here is the how i am generating the onclick event: <a id="forgotPasswordLink" href="#" onclick="openSupportPage();"> Some Text </a> The onclick function is defined this way: function openSupportPage() { var features = "width=700,height=400,status=yes,toolbar=no,menubar=no,location=no,scrollbars=yes"; var winId = window.open('', '', features); winId.focus(); winId.document.open(); winId.document.write('<html><head><title>' + document.title + '</title><link rel="stylesheet" href="./css/default.css" type="text/css">\n'); var is_ie6 = ( window.external && typeof window.XMLHttpRequest == "undefined"); alert(is_ie6);/*The JS include below*/ /*works in popup only with this alert box.*/ /*else IE8 Hangs*/ winId.document.write('<script src="../js/tiny_mce/tiny_mce.js" type="text/javascript">Script_IE8</script>\n'); winId.document.write('<script type="text/javascript">\n'); winId.document.write('function inittextarea() {\n'); winId.document.write('tinyMCE.init({ \n'); winId.document.write('elements : "content",\n'); winId.document.write('theme : "advanced",\n'); winId.document.write('readonly : true,\n'); winId.document.write('mode : "exact",\n'); winId.document.write('theme : "advanced",\n'); winId.document.write('readonly : true,\n'); winId.document.write('setup : function(ed) {\n'); winId.document.write('ed.onInit.add(function() {\n'); winId.document.write('tinyMCE.activeEditor.execCommand("mceToggleVisualAid");\n'); winId.document.write('});\n'); winId.document.write('}\n'); winId.document.write('});}</script>\n'); winId.document.write('</head><body onload="inittextarea()">\n'); winId.document.write(' \n'); var hiddenFrameHTML = document.getElementById("HiddenFrame").innerHTML; hiddenFrameHTML = hiddenFrameHTML.replace(/&amp;/gi, "&"); hiddenFrameHTML = hiddenFrameHTML.replace(/&lt;/gi, "<"); hiddenFrameHTML = hiddenFrameHTML.replace(/&gt;/gi, ">"); winId.document.write(hiddenFrameHTML); winId.document.write('<textarea id="content" rows="10" style="width:100%">\n'); winId.document.write(document.getElementById(top.document.forms[0].id + ":supportStuff").innerHTML); winId.document.write('</textArea>\n'); var hiddenFrameHTML2 = document.getElementById("HiddenFrame2").innerHTML; hiddenFrameHTML2 = hiddenFrameHTML2.replace(/&amp;/gi, "&"); hiddenFrameHTML2 = hiddenFrameHTML2.replace(/&lt;/gi, "<"); hiddenFrameHTML2 = hiddenFrameHTML2.replace(/&gt;/gi, ">"); winId.document.write(hiddenFrameHTML2); winId.document.write('</body></html>\n'); winId.document.close(); } Please help me on this one.

  • Event bubbling with img tags?

    - by Kenny Bones
    I did some googling and figured I'm probably experiencing so called "event bubbling" that I've never heard of but are not surprised by it's existance. I want it to fire only once and I'm wondering how to fix this. Basically, I have this small code snippet: $('.bggallery_images').click(function () { alert('test'); }); This is supposed to fire once from a php snippet that basically adds an image of each image from a specific folder. It then outputs an echo string where each image has the class of "bggallery_images". PHP snippet looks like this: <?php $dirname = "img"; $images = scandir($dirname); $ignore = Array(".", ".."); foreach($images as $file) { if(!in_array($file, $ignore)) { echo "<img class=\"bggallery_images\" src=\"$dirname/$file\" />"; }; } ?> This all generates the html markup that looks like this for each image: <img src="img/WhitePattern6.gif" class="bggallery_images"> What is happening here? Here's the rendered output from FireBug: <div id="gallery_lightbox" style="height: 215px; z-index: 4; display: block;"> <div id="close"></div> <h2><cufon class="cufon cufon-canvas" alt="Velg " style="width: 39px; height: 20px;"><canvas width="49" height="23" style="width: 49px; height: 23px; top: -4px; left: 0px;"></canvas><cufontext>Velg </cufontext></cufon><cufon class="cufon cufon-canvas" alt="bakgrunnsbilde" style="width: 123px; height: 20px;"><canvas width="129" height="23" style="width: 129px; height: 23px; top: -4px; left: 0px;"></canvas><cufontext>bakgrunnsbilde</cufontext></cufon></h2> <div class="bggallery_images">testererererer</div> <img src="img/Bakgrunner/4462-v4.jpg" class="bggallery_images"><img src="img/Bakgrunner/5922.gif" class="bggallery_images"><img src="img/Bakgrunner/BluePattern.gif" class="bggallery_images"><img src="img/Bakgrunner/Brown1.gif" class="bggallery_images"><img src="img/Bakgrunner/Brown2Pattern.jpg" class="bggallery_images"><img src="img/Bakgrunner/BrownPattern.jpg" class="bggallery_images"><img src="img/Bakgrunner/Brownn.gif" class="bggallery_images"><img src="img/Bakgrunner/GrayPattern.gif" class="bggallery_images"><img src="img/Bakgrunner/GreenPattern3.gif" class="bggallery_images"><img src="img/Bakgrunner/OrangePattern.gif" class="bggallery_images"><img src="img/Bakgrunner/PurplePattern.gif" class="bggallery_images"><img src="img/Bakgrunner/PurplePattern2.gif" class="bggallery_images"><img src="img/Bakgrunner/RedPattern3.gif" class="bggallery_images"><img src="img/Bakgrunner/RedPattern4.gif" class="bggallery_images"><img src="img/Bakgrunner/RedPattern5.gif" class="bggallery_images"><img src="img/Bakgrunner/Tiled_Wallpaper__Green_Texture_by_knitetgantt.png" class="bggallery_images"><img src="img/Bakgrunner/WhitePattern4.gif" class="bggallery_images"><img src="img/Bakgrunner/WhitePattern5.gif" class="bggallery_images"><img src="img/Bakgrunner/WhitePattern6.gif" class="bggallery_images"><img src="img/Bakgrunner/WhitePattern7.gif" class="bggallery_images"><img src="img/Bakgrunner/WhitePurple.jpg" class="bggallery_images"><img src="img/Bakgrunner/YellowPattern.gif" class="bggallery_images"><img src="img/Bakgrunner/vintage-wallpaper.jpg" class="bggallery_images"> </div>

  • SQL Server stored procedures - update column based on variable name..?

    - by ClarkeyBoy
    Hi, I have a data driven site with many stored procedures. What I want to eventually be able to do is to say something like: For Each @variable in sproc inputs UPDATE @TableName SET @variable.toString = @variable Next I would like it to be able to accept any number of arguments. It will basically loop through all of the inputs and update the column with the name of the variable with the value of the variable - for example column "Name" would be updated with the value of @Name. I would like to basically have one stored procedure for updating and one for creating. However to do this I will need to be able to convert the actual name of a variable, not the value, to a string. Question 1: Is it possible to do this in T-SQL, and if so how? Question 2: Are there any major drawbacks to using something like this (like performance or CPU usage)? I know if a value is not valid then it will only prevent the update involving that variable and any subsequent ones, but all the data is validated in the vb.net code anyway so will always be valid on submitting to the database, and I will ensure that only variables where the column exists are able to be submitted. Many thanks in advance, Regards, Richard Clarke Edit: I know about using SQL strings and the risk of SQL injection attacks - I studied this a bit in my dissertation a few weeks ago. Basically the website uses an object oriented architecture. There are many classes - for example Product - which have many "Attributes" (I created my own class called Attribute, which has properties such as DataField, Name and Value where DataField is used to get or update data, Name is displayed on the administration frontend when creating or updating a Product and the Value, which may be displayed on the customer frontend, is set by the administrator. DataField is the field I will be using in the "UPDATE Blah SET @Field = @Value". I know this is probably confusing but its really complicated to explain - I have a really good understanding of the entire system in my head but I cant put it into words easily. Basically the structure is set up such that no user will be able to change the value of DataField or Name, but they can change Value. I think if I were to use dynamic parameterised SQL strings there will therefore be no risk of SQL injection attacks. I mean basically loop through all the attributes so that it ends up like: UPDATE Products SET [Name] = '@Name', Description = '@Description', Display = @Display Then loop through all the attributes again and add the parameter values - this will have the same effect as using stored procedures, right?? I dont mind adding to the page load time since this is mainly going to affect the administration frontend, and will marginly affect the customer frontend.

  • How to bind Lists of a custom view model to a dropDownList an get the selected value after POST in A

    - by user187220
    I have following problem. In my view model I defined some list properties as follows: public class BasketAndOrderSearchCriteriaViewModel { List<KeyValuePair> currencies; public ICollection<KeyValuePair> Currencies { get { if (this.currencies == null) this.currencies = new List<KeyValuePair>(); return this.currencies; } } List<KeyValuePair> deliverMethods; public ICollection<KeyValuePair> DeliveryMethods { get { if (this.deliverMethods == null) this.deliverMethods = new List<KeyValuePair>(); return this.deliverMethods; } } } This view model is embedded in another view model: public class BasketAndOrderSearchViewModel { public BasketAndOrderSearchCriteriaViewModel Criteria { [System.Diagnostics.DebuggerStepThrough] get { return this.criteria; } } } I use 2 action methods; one is for the GET and the other for POST: [HttpGet] public ActionResult Search(BasketAndOrderSearchViewModel model){...} [HttpPost] public ActionResult SubmitSearch(BasketAndOrderSearchViewModel model){...} In the view I implement the whole view model by using the EditorFor-Html Helper which does not want to automatically display DropDownLists for List properties! 1. Question: How can you let EditorFor display DropDownLists? Since I could not figure out how to display DropDownLists by using EditorFor, I used the DropDownList Html helper and filled it through the view model as follows: public IEnumerable<SelectListItem> DeliveryMethodAsSelectListItem() { List<SelectListItem> list = new List<SelectListItem>(); list.Add(new SelectListItem() { Selected = true, Text = "<Choose Delivery method>", Value = "0" }); foreach (var item in this.DeliveryMethods) { list.Add(new SelectListItem() { Selected = false, Text = item.Value, Value = item.Key }); } return list; } My 2. question: As you can see I pass my view model to the action metho with POST attribute! Is there a way to get the selected value of a DropDownList get binded to the passed view model? At the moment all the DropDownList are empty and the selected value can only be fetched by the Request.Form which I definitely want to avoid! I would greatly appreciate some ideas or tips on this!

  • Scriptaculous Draggable/Droppable script not working properly when dragging into a scrolling div

    - by George
    I am using the Scriptaculous Draggable/Droppable scripts and have a problem when dragging into a scrolling div. I have the following layout (based on this question): #grid-container { left:33px; position:relative; width:300px; } #grid { width:310px; height:400px; overflow:auto; margin-bottom: 15px; } #grid-container ul { width:400px; list-style-type:none; white-space: nowrap; } #grid-container li { display:inline; list-style-type:none; padding:5px 15px 5px 15px; height:88px; text-align:center } .image-row { margin-left: 10px; } .grid-image { height:50px; margin-left:-20px; } Here is the html: <div id="grid-container"> <div id="grid"> <div id="row1" class="image-row"> <ul> <li><img id="img1" class="grid-image" src="images/img1.jpg"></li> <li><img id="img2" class="grid-image" src="images/img2.jpg"></li> <li><img id="img3" class="grid-image" src="images/img3.jpg"></li> <li><img id="img4" class="grid-image" src="images/img4.jpg"></li> </ul> </div> <div id="row2" class="image-row"> <ul> <li><img id="img5" class="grid-image" src="images/img5.jpg"></li> <li><img id="img6" class="grid-image" src="images/img6.jpg"></li> </ul> </div> </div> </div> I have another div with draggable items, while all of the img elements are droppable. This works very well for most cases, but when there are too many images for the grid and it has to scroll, I run into issues. I can still drag/drop into most items in that div, but when I scroll down and then try to drag onto an item in the bottom of the list, it drops on the row that was at the bottom before I scrolled the div. Even if I set the scroll attribute when creating the Draggable items, it will scroll the grid div, but not use the proper Droppable item. Is there any way to make the Draggable items drop onto the proper Droppable element regardless of if the containing div is scrolled or not?

  • What's the use of Ant's extension-point if/unless attributes?

    - by Robert Menteer
    When you define an extension-point in an Ant build file you can have it conditional by using the if or unless attribute. On a target the if/unless prevent it's tasks from being run. But an extension-point doesn't have any tasks to conditionally run, so what does the condition do? My thought (which proved to be incorrect in Ant 1.8.0) is it would prevent any tasks that extend the extension-point from being run. Here is an example build script showing the problem: <project name = "ext-test" default = "main"> <property name = "do.it" value = "false" /> <extension-point name = "init"/> <extension-point name = "doit" depends = "init" if = "${do.it}" /> <target name = "extend-init" extensionOf = "init"> <echo message = "Doing extend-init." /> </target> <target name = "extend-doit" extensionOf = "doit"> <echo message = "Do It! (${do.it})" /> </target> <target name = "main" depends = "doit"> <echo message = "Doing main." /> </target> </project> Using the command: ant -v Relults in: Apache Ant version 1.8.0 compiled on February 1 2010 Trying the default build file: build.xml Buildfile: /Users/bob/build.xml Detected Java version: 1.6 in: /System/Library/Frameworks/JavaVM.framework/Versions/1.6.0/Home Detected OS: Mac OS X parsing buildfile /Users/bob/build.xml with URI = file:/Users/bob/build.xml Project base dir set to: /Users/bob parsing buildfile jar:file:/Users/bob/Documents/Development/3P-Tools/apache-ant-1.8.0/lib/ant.jar!/org/apache/tools/ant/antlib.xml with URI = jar:file:/Users/bob/Documents/Development/3P-Tools/apache-ant-1.8.0/lib/ant.jar!/org/apache/tools/ant/antlib.xml from a zip file Build sequence for target(s) `main' is [extend-init, init, extend-doit, doit, main] Complete build sequence is [extend-init, init, extend-doit, doit, main, ] extend-init: [echo] Doing extend-init. init: extend-doit: [echo] Do It! (false) doit: Skipped because property 'false' not set. main: [echo] Doing main. BUILD SUCCESSFUL Total time: 0 seconds You will notice the target extend-doit is executed but the extention-point itself is skipped. Since an extention-point doesn't have any tasks exactly what has been skipped? Any targets that depend on the extention-point still get executed since a skipped target is a successful target. What is the value of the if/unless attributes on an extention-point?

  • How to add CSS classes to Zend_Form_Element_Select option

    - by Jah Selassie
    Hi, I'm trying to add a CSS class to a Zend_Form_Element_Select option, but I just can't find a way to do it. The desired output would be something like this: <select name="hey" id="hey"> <option value="value1" style="parent">label1</option> <option value="value2" style="sibling">sublabel1</option> <option value="value3" style="sibling">sublabel2</option> <option value="value4" style="parent">label2</option> <option value="value5" style="sibling">sublabel3</option> <option value="value6" style="sibling">sublabel4</option> </select> But I'm getting this: <select name="hey" id="hey"> <option value="value1">label1</option> <option value="value2">sublabel1</option> <option value="value3">sublabel2</option> <option value="value4">label2</option> <option value="value5">sublabel3</option> <option value="value6">sublabel4</option> </select> I can't seem to pass a CSS class attribute to any of the options in the select element although I can style the select element itselft. My code: $sel = new Zend_Form_Element_Select('hey'); $sel->setRequired(true)->setLabel('Select an Option:'); $sel->addMultiOption('value1', 'label1', array('class' => 'parent')) ->addMultiOption('value2', 'sublabel1', array('class' => 'sibling')) (etc...); After researching a bit I found out that Element_Select doesn't have a method for adding CSS styles to the options in the select box, only for the select itself. So, how can I add them? Should I extend the form_element_select? Or would a custom decorator suffice? Can anyone give me a hint? I'm baffled with this. Thanks in advance!

  • Difficulties getting GraphViz working as a library in C++

    - by DistortedLojik
    Am working on a program that will allow a graph of nodes to be displayed and then updated visually as the nodes themselves are updated.

  • Mapstraction: Changing an Icon's image URL after it has been added?

    - by Paul Owens
    I am trying to use marker.setIcon() to change a markers image. However it appears that although this changes the marker.iconUrl attribute the icon itself is using marker.proprietary_marker.$.icon.image to display the markers image - so the markers icon remains unchanged. Is there a way to dynamically change the marker.proprietary_marker.$.icon.image? Add a marker. Check the icon's image url and the proprietary icon's image - they're the same. Change the icon. Again check the Urls.

  • How can I highlight empty fields in ASP.NET MVC 2 before model binding has occurred?

    - by Richard Poole
    I'm trying to highlight certain form fields (let's call them important fields) when they're empty. In essence, they should behave a bit like required fields, but they should be highlighted if they are empty when the user first GETs the form, before POST & model validation has occurred. The user can also ignore the warnings and submit the form when these fields are empty (i.e. empty important fields won't cause ModelState.IsValid to be false). Ideally it needs to work server-side (empty important fields are highlighted with warning message on GET) and client-side (highlighted if empty when losing focus). I've thought of a few ways of doing this, but I'm hoping some bright spark can come up with a nice elegant solution... Just use a CSS class to flag important fields Update every view/template to render important fields with an important CSS class. Write some jQuery to highlight empty important fields when the DOM is ready and hook their blur events so highlights & warning messages can be shown/hidden as appropriate. Pros: Quick and easy. Cons: Unnecessary duplication of importance flags and warning messages across views & templates. Clients with JavaScript disabled will never see highlights/warnings. Custom data annotation and client-side validator Create classes similar to RequiredAttribute, RequiredAttributeAdapter and ModelClientValidationRequiredRule, and register the adapter with DataAnnotationsModelValidatorProvider.RegisterAdapter. Create a client-side validator like this that responds to the blur event. Pros: Data annotation follows DRY principle (Html.ValidationMessageFor<T> picks up field importance and warning message from attribute, no duplication). Cons: Must call TryValidateModel from GET actions to ensure empty fields are decorated. Not technically validation (client- & server-side rules don't match) so it's at the mercy of framework changes. Clients with JavaScript disabled will never see highlights/warnings. Clone the entire validation framework It strikes me that I'm trying to achieve exactly the same thing as validation but with warnings rather than errors. It needs to run before model binding (and therefore validation) has occurred. Perhaps it's worth designing a similar framework with annotations like Required, RegularExpression, StringLength, etc. that somehow cause Html.TextBoxFor<T> etc. to render the warning CSS class and Html.ValidationMessageFor<T> to emit the warning message and JSON needed to enable client-side blur checks. Pros: Sounds like something MVC 2 could do with out of the box. Cons: Way too much effort for my current requirement! I'm swaying towards option 1. Can anyone think of a better solution?

  • How to write this Linq SQL as a Dynamic Query (using strings)?

    - by Dr. Zim
    Skip to the "specific question" as needed. Some background: The scenario: I have a set of products with a "drill down" filter (Query Object) populated with DDLs. Each progressive DDL selection will further limit the product list as well as what options are left for the DDLs. For example, selecting a hammer out of tools limits the Product Sizes to only show hammer sizes. Current setup: I created a query object, sent it to a repository, and fed each option to a SQL "table valued function" where null values represent "get all products". I consider this a good effort, but far from DDD acceptable. I want to avoid any "programming" in SQL, hopefully doing everything with a repository. Comments on this topic would be appreciated. Specific question: How would I rewrite this query as a Dynamic Query? A link to something like 101 Linq Examples would be fantastic, but with a Dynamic Query scope. I really want to pass to this method the field in quotes "" for which I want a list of options and how many products have that option. from p in db.Products group p by p.ProductSize into g select new Category { PropertyType = g.Key, Count = g.Count() } Each DDL option will have "The selection (21)" where the (21) is the quantity of products that have that attribute. Upon selecting an option, all other remaining DDLs will update with the remaining options and counts. Edit: Additional notes: .OrderBy("it.City") // "it" refers to the entire record .GroupBy("City", "new(City)") // This produces a unique list of City .Select("it.Count()") //This gives a list of counts... getting closer .Select("key") // Selects a list of unique City .Select("new (key, count() as string)") // +1 to me LOL. key is a row of group .GroupBy("new (City, Manufacturer)", "City") // New = list of fields to group by .GroupBy("City", "new (Manufacturer, Size)") // Second parameter is a projection Product .Where("ProductType == @0", "Maps") .GroupBy("new(City)", "new ( null as string)")// Projection not available later? .Select("new (key.City, it.count() as string)")// GroupBy new makes key an object Product .Where("ProductType == @0", "Maps") .GroupBy("new(City)", "new ( null as string)")// Projection not available later? .Select("new (key.City, it as object)")// the it object is the result of GroupBy var a = Product .Where("ProductType == @0", "Maps") .GroupBy("@0", "it", "City") // This fails to group Product at all .Select("new ( Key, it as Product )"); // "it" is property cast though What I have learned so far is LinqPad is fantastic, but still looking for an answer. Eventually, completely random research like this will prevail I guess. LOL. Edit:

  • CSS selectors : should I make my CSS easier to read or optimise the speed

    - by Laurent Bourgault-Roy
    As I was working on a small website, I decided to use the PageSpeed extension to check if their was some improvement I could do to make the site load faster. However I was quite surprise when it told me that my use of CSS selector was "inefficient". I was always told that you should keep the usage of the class attribute in the HTML to a minimum, but if I understand correctly what PageSpeed tell me, it's much more efficient for the browser to match directly against a class name. It make sense to me, but it also mean that I need to put more CSS classes in my HTML. It make my .css file harder to read. I usually tend to mark my CSS like this : #mainContent p.productDescription em.priceTag { ... } Which make it easy to read : I know this will affect the main content and that it affect something in a paragraph tag (so I wont start to put all sort of layout code in it) that describe a product and its something that need emphasis. However it seem I should rewrite it as .priceTag { ... } Which remove all context information about the style. And if I want to use differently formatted price tag (for example, one in a list on the sidebar and one in a paragraph), I need to use something like that .paragraphPriceTag { ... } .listPriceTag { ... } Which really annoy me since I seem to duplicate the semantic of the HTML in my classes. And that mean I can't put common style in an unqualified .priceTag { ... } and thus I need to replicate the style in both CSS rule, making it harder to make change. (Altough for that I could use multiple class selector, but IE6 dont support them) I believe making code harder to read for the sake of speed has never been really considered a very good practice . Except where it is critical, of course. This is why people use PHP/Ruby/C# etc. instead of C/assembly to code their site. It's easier to write and debug. So I was wondering if I should stick with few CSS classes and complex selector or if I should go the optimisation route and remove my fancy CSS selectors for the sake of speed? Does PageSpeed make over the top recommandation? On most modern computer, will it even make a difference?

  • Is x a reserved keyword in Javascript FF/Safari not in IE?

    - by Marco Demaio
    A web page of a web application was showing a strange error. I regressively removed all the HTML/CSS/JS code and arrived to the basic and simple code below. <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html><head> <title>test</title> <script type="text/javascript"> var TestObj = { foo: function() {} } alert(x); //ok displays "undefined" var x = TestObj.foo; var z = TestObj.foo; </script> </head><body> <p onclick='alert(x);'>Click shows function foo!</p> <img onclick='alert(x);' alt='CRAZY click displays a number in FF/Safari not function foo' src='' style='display: block; width: 100px; height: 100px; border: 1px solid #00ff00;'> <p onclick='alert(x);'>Click shows function foo!</p> </body></html> It's crazy: when clicking on P elements the string "function(){}" is displaied as expected. But when clicking on IMG element it shows a number as if x function got in some way removed from memory or deinstantiated (it does not even show x as "undefined" but as a number). To let you test it quickly I placed the working test above also here. This can be reproduced on both Firefox 3.6 and Safari 4.0.4. Everything works properly only on IE7+. I'm really clueless, I was wondering if x is maybe a reserved keyword in JS Firefox/Safari. Thanks to anyone who could help! FYI: if you repalce x() with z() everything work prefectly in all browsers (this is even more crazy to me) adding a real image in src attribute does not fix the problem removing style in img does not fix the problem (i gave style to image only to help you clicking on image thus you can see the imnage border)

  • How to programmatically bind to a Core Data model?

    - by Dave Gallagher
    Hello. I have a Core Data model, and was wondering if you know how to create a binding to an Entity, programmatically? Normally you use bind:toObject:withKeyPath:options: to create a binding. But I'm having a little difficulty getting this to work with Core Data, and couldn't find anything in Apple's docs regarding doing this programmatically. The Core Data model is simple: An Entity called Book An Attribute of Book called author (NSString) I have an object called BookController. It looks like so: @interface BookController : NSObject { NSString *anAuthor; } @property (nonatomic, retain) NSString *anAuthor; // @synthesize anAuthor; inside @implementation I'd like to bind anAuthor inside BookController, to author inside a Book entity. This is how I'm attempting to wrongly do it (it partially works): // A custom class I made, providing an interface to the Core Data database CoreData *db = [[CoreData alloc] init]; // Creating a Book entity, saving it [db addMocObject:@"Book"]; [db saveMoc]; // Fetching the Book entity we just created NSArray *books = [db fetchObjectsForEntity:@"Book" withPredicate:nil withSortDescriptors:nil]; NSManagedObject *book = [books objectAtIndex:0]; // Creating the binding BookController *bookController = [[BookController alloc] init]; [bookController bind:@"anAuthor" toObject:book withKeyPath:@"author" options:nil]; // Manipulating the binding [bookController setAnAuthor:@"Bill Gates"]; Now, when updating from the perspective of bookController, things don't work quite right: // Testing the binding from the bookController's perspective [bookController setAnAuthor:@"Bill Gates"]; // Prints: "bookController's anAuthor: Bill Gates" NSLog(@"bookController's anAuthor: %@", [bookController anAuthor]); // OK! // ERROR HERE - Prints: "bookController's anAuthor: (null)" NSLog(@"Book's author: %@", [book valueForKey:@"author"]); // DOES NOT WORK! :( When updating from the perspective of the Book entity, things work fine: // ------------------------------ // Testing the binding from the Book's (Entity) perspective (this works perfect) [book setValue:@"Steve Jobs" forKey:@"author"]; // Prints: "bookController's anAuthor: Steve Jobs" NSLog(@"bookController's anAuthor: %@", [bookController anAuthor]); // OK! // Prints: "bookController's anAuthor: Steve Jobs" NSLog(@"Book's author: %@", [book valueForKey:@"author"]); // OK! It appears that the binding is partially working. I can update it on the side of the Model and it propagates up to the Controller via KVO, but if I update it on the side of the Controller, it doesn't trickle down to the Model via KVC. Any idea on what I'm doing wrong? Thanks so much for looking! :)

  • SharePoint: Problem with BaseFieldControl

    - by Anoop
    Hi All, In below code in a Gird First column is BaseFieldControl from a column of type Choice of SPList. Secound column is a text box control with textchange event. Both the controls are created at rowdatabound event of gridview. Now the problem is that when Steps: 1) select any of the value from BaseFieldControl(DropDownList) which is rendered from Choice Column of SPList 2) enter any thing in textbox in another column of grid. 3) textchanged event fires up and in textchange event rebound the grid. Problem: the selected value becomes the first item or the default value(if any). but if i do not rebound the grid at text changed event it works fine. Please suggest what to do. using System; using Microsoft.SharePoint; using Microsoft.SharePoint.WebControls; using System.Web.UI; using System.Web.UI.WebControls; using System.Data; namespace SharePointProjectTest.Layouts.SharePointProjectTest { public partial class TestBFC : LayoutsPageBase { GridView grid = null; protected void Page_Load(object sender, EventArgs e) { try { grid = new GridView(); grid.ShowFooter = true; grid.ShowHeader = true; grid.AutoGenerateColumns = true; grid.ID = "grdView"; grid.RowDataBound += new GridViewRowEventHandler(grid_RowDataBound); grid.Width = Unit.Pixel(900); MasterPage holder = (MasterPage)Page.Controls[0]; holder.FindControl("PlaceHolderMain").Controls.Add(grid); DataTable ds = new DataTable(); ds.Columns.Add("Choice"); //ds.Columns.Add("person"); ds.Columns.Add("Curr"); for (int i = 0; i < 3; i++) { DataRow dr = ds.NewRow(); ds.Rows.Add(dr); } grid.DataSource = ds; grid.DataBind(); } catch (Exception ex) { } } void tx_TextChanged(object sender, EventArgs e) { DataTable ds = new DataTable(); ds.Columns.Add("Choice"); ds.Columns.Add("Curr"); for (int i = 0; i < 3; i++) { DataRow dr = ds.NewRow(); ds.Rows.Add(dr); } grid.DataSource = ds; grid.DataBind(); } void grid_RowDataBound(object sender, GridViewRowEventArgs e) { if (e.Row.RowType == DataControlRowType.DataRow) { SPWeb web = SPContext.Current.Web; SPList list = web.Lists["Source for test"]; SPField field = list.Fields["Choice"]; SPListItem item=list.Items.Add(); BaseFieldControl control = (BaseFieldControl)GetSharePointControls(field, list, item, SPControlMode.New); if (control != null) { e.Row.Cells[0].Controls.Add(control); } TextBox tx = new TextBox(); tx.AutoPostBack = true; tx.ID = "Curr"; tx.TextChanged += new EventHandler(tx_TextChanged); e.Row.Cells[1].Controls.Add(tx); } } public static Control GetSharePointControls(SPField field, SPList list, SPListItem item, SPControlMode mode) { if (field == null || field.FieldRenderingControl == null || field.Hidden) return null; try { BaseFieldControl webControl = field.FieldRenderingControl; webControl.ListId = list.ID; webControl.ItemId = item.ID; webControl.FieldName = field.Title; webControl.ID = "id_" + field.InternalName; webControl.ControlMode = mode; webControl.EnableViewState = true; return webControl; } catch (Exception ex) { return null; } } } }

  • Python form POST using urllib2 (also question on saving/using cookies)

    - by morpheous
    I am trying to write a function to post form data and save returned cookie info in a file so that the next time the page is visited, the cookie information is sent to the server (i.e. normal browser behavior). I wrote this relatively easily in C++ using curlib, but have spent almost an entire day trying to write this in Python, using urllib2 - and still no success. This is what I have so far: import urllib, urllib2 import logging # the path and filename to save your cookies in COOKIEFILE = 'cookies.lwp' cj = None ClientCookie = None cookielib = None logger = logging.getLogger(__name__) # Let's see if cookielib is available try: import cookielib except ImportError: logger.debug('importing cookielib failed. Trying ClientCookie') try: import ClientCookie except ImportError: logger.debug('ClientCookie isn\'t available either') urlopen = urllib2.urlopen Request = urllib2.Request else: logger.debug('imported ClientCookie succesfully') urlopen = ClientCookie.urlopen Request = ClientCookie.Request cj = ClientCookie.LWPCookieJar() else: logger.debug('Successfully imported cookielib') urlopen = urllib2.urlopen Request = urllib2.Request # This is a subclass of FileCookieJar # that has useful load and save methods cj = cookielib.LWPCookieJar() login_params = {'name': 'anon', 'password': 'pass' } def login(theurl, login_params): init_cookies(); data = urllib.urlencode(login_params) txheaders = {'User-agent' : 'Mozilla/4.0 (compatible; MSIE 5.5; Windows NT)'} try: # create a request object req = Request(theurl, data, txheaders) # and open it to return a handle on the url handle = urlopen(req) except IOError, e: log.debug('Failed to open "%s".' % theurl) if hasattr(e, 'code'): log.debug('Failed with error code - %s.' % e.code) elif hasattr(e, 'reason'): log.debug("The error object has the following 'reason' attribute :"+e.reason) sys.exit() else: if cj is None: log.debug('We don\'t have a cookie library available - sorry.') else: print 'These are the cookies we have received so far :' for index, cookie in enumerate(cj): print index, ' : ', cookie # save the cookies again cj.save(COOKIEFILE) #return the data return handle.read() # FIXME: I need to fix this so that it takes into account any cookie data we may have stored def get_page(*args, **query): if len(args) != 1: raise ValueError( "post_page() takes exactly 1 argument (%d given)" % len(args) ) url = args[0] query = urllib.urlencode(list(query.iteritems())) if not url.endswith('/') and query: url += '/' if query: url += "?" + query resource = urllib.urlopen(url) logger.debug('GET url "%s" => "%s", code %d' % (url, resource.url, resource.code)) return resource.read() When I attempt to log in, I pass the correct username and pwd,. yet the login fails, and no cookie data is saved. My two questions are: can anyone see whats wrong with the login() function, and how may I fix it? how may I modify the get_page() function to make use of any cookie info I have saved ?

  • How to avoid this PDO exception: Cannot execute queries while other unbuffered queries are active

    - by Vittorio Vittori
    Hi, I'd like to print a simple table in my page with 3 columns, building name, tags and architecture style. If I try to retrieve the list of building names and arch. styles there is no problem: SELECT buildings.name, arch_styles.style_name FROM buildings INNER JOIN buildings_arch_styles ON buildings.id = buildings_arch_styles.building_id INNER JOIN arch_styles ON arch_styles.id = buildings_arch_styles.arch_style_id LIMIT 0, 10 My problem starts on retreaving the first 5 tags for every building of the query I've just wrote. SELECT DISTINCT name FROM tags INNER JOIN buildings_tags ON buildings_tags.tag_id = tags.id AND buildings_tags.building_id = 123 LIMIT 0, 5 The query itself works perfectly, but not where I thought to use it: <?php // pdo connection allready active, i'm using mysql $pdo_conn->setAttribute(PDO::MYSQL_ATTR_USE_BUFFERED_QUERY, true); $sql = "SELECT buildings.name, buildings.id, arch_styles.style_name FROM buildings INNER JOIN buildings_arch_styles ON buildings.id = buildings_arch_styles.building_id INNER JOIN arch_styles ON arch_styles.id = buildings_arch_styles.arch_style_id LIMIT 0, 10"; $buildings_stmt = $pdo_conn->prepare ($sql); $buildings_stmt->execute (); $buildings = $buildings_stmt->fetchAll (PDO::FETCH_ASSOC); $sql = "SELECT DISTINCT name FROM tags INNER JOIN buildings_tags ON buildings_tags.tag_id = tags.id AND buildings_tags.building_id = :building_id LIMIT 0, 5"; $tags_stmt = $pdo_conn->prepare ($sql); $html = "<table>"; // i'll use it to print my table foreach ($buildings as $building) { $name = $building["name"]; $style = $building["style_name"]; $id = $building["id"]; $tags_stmt->bindParam (":building_id", $id, PDO::PARAM_INT); $tags_stmt->execute (); // the problem is HERE $tags = $tags_stmt->fetchAll (PDO::FETCH_ASSOC); $html .= "... $name ... $style"; foreach ($tags as $current_tag) { $tag = $current_tag["name"]; $html .= "... $tag ..."; // let's suppose this is an area of the table where I print the first 5 tags per building } } $html .= "...</table>"; print $html; I'm not experienced on queries, so i though something like this, but it throws the error: PHP Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[HY000]: General error: 2014 Cannot execute queries while other unbuffered queries are active. Consider using PDOStatement::fetchAll(). Alternatively, if your code is only ever going to run against mysql, you may enable query buffering by setting the PDO::MYSQL_ATTR_USE_BUFFERED_QUERY attribute. What can I do to avoid this? Should I change all and search a different way to get this kind of queries?

  • Tridion New UI Preview Site is not reflecting with the changes unless pulished

  • Multiple views and source list in a Core Data app

    - by Ellie P.
    I'm working on my first major Cocoa app for an undergraduate research project. The application is document-based and uses Core Data. One of the entities is an abstract entity, Page. Page is parent of several types of pages: ie PageWithHeaderAndFooter, PageWithTwoColumns, BasicPage etc. Page has attributes, such as title and author, that all pages have in common. Each specific type of page has a certain number of layout blocks (PageWithHeaderAndFooter has three: header, footer, body. BasicPage has one: body. etc.) Additionally, all Page subclasses define layout-specific implementations of certain methods. The other relevant entity is Style, which defines the visual look of a Page. (Think of Pages as HTML and Style as CSS.) I would like my app to have an iTunes/Mail-like source list with sections. (One section would be Pages, the other would be Styles.) I have a pretty good idea how to do the sectioned source list (this was a great help). However, after hours of headbanging and fruitless googling, here's what I can't figure out: Pages and Styles listed in the source list, and when you select one of them, all of the relevant fields for that object appear at the right (mostly NSTextViews, pop up menus, etc). I laid that out and did all of the bindings in Interface Builder. The problem is, if my source list contains different types of pages, how do I get a different view to display at the right depending on the type of page selected? For example, if a BasicPage is selected, I want just what you see above: the general page stuff and one NSTextView that corresponds to the one field body of BasicPage. But if I select a PageWithHeaderAndFooter, I want to display the general page stuff plus three NSTextViews (one for header, body, and footer.) If I have a Style selected, I want to display various pop up menus, color wells, etc. For the pages at least, we're only talking about one or more NSTextViews, each of which corresponds to a String attribute of the respective entity. How would you do this? Thank you for your help!

  • Spring AOP pointcut that matches annotation on interface

    - by seanizer
    Hello, this is my first post here, so I apologize in advance for any stupidity on my side. I have a service class implemented in Java 6 / Spring 3 that needs an annotation to restrict access by role. I have defined an annotation called RequiredPermission that has as its value attribute one or more values from an enum called OperationType: public @interface RequiredPermission { /** * One or more {@link OperationType}s that map to the permissions required * to execute this method. * * @return */ OperationType[] value();} public enum OperationType { TYPE1, TYPE2; } package com.mycompany.myservice; public interface MyService{ @RequiredPermission(OperationType.TYPE1) void myMethod( MyParameterObject obj ); } package com.mycompany.myserviceimpl; public class MyServiceImpl implements MyService{ public myMethod( MyParameterObject obj ){ // do stuff here } } I also have the following aspect definition: /** * Security advice around methods that are annotated with * {@link RequiredPermission}. * * @param pjp * @param param * @param requiredPermission * @return * @throws Throwable */ @Around(value = "execution(public *" + " com.mycompany.myserviceimpl.*(..))" + " && args(param)" + // parameter object " && @annotation( requiredPermission )" // permission annotation , argNames = "param,requiredPermission") public Object processRequest(final ProceedingJoinPoint pjp, final MyParameterObject param, final RequiredPermission requiredPermission) throws Throwable { if(userService.userHasRoles(param.getUsername(),requiredPermission.values()){ return pjp.proceed(); }else{ throw new SorryButYouAreNotAllowedToDoThatException( param.getUsername(),requiredPermission.value()); } } The parameter object contains a user name and I want to look up the required role for the user before allowing access to the method. When I put the annotation on the method in MyServiceImpl, everything works just fine, the pointcut is matched and the aspect kicks in. However, I believe the annotation is part of the service contract and should be published with the interface in a separate API package. And obviously, I would not like to put the annotation on both service definition and implementation (DRY). I know there are cases in Spring AOP where aspects are triggered by annotations one interface methods (e.g. Transactional). Is there a special syntax here or is it just plain impossible out of the box. PS: I have not posted my spring config, as it seems to be working just fine. And no, those are neither my original class nor method names. Thanks in advance, Sean PPS: Actually, here is the relevant part of my spring config: <aop:aspectj-autoproxy proxy-target-class="false" /> <bean class="com.mycompany.aspect.MyAspect"> <property name="userService" ref="userService" /> </bean>

  • Search for multiple values in an xml column

I also have a table Word which has WordId and WordText. Xml for Message.WordIndex has the following schema: <xs:schema attributeFormDefault="unqualified" elementFormDefault="qualified" xmlns:xs="http://www.w3.org/2001/XMLSchema" targetNamespace="http://www.example.com"> <xs:element name="wi"> <xs:complexType> <xs:sequence> <xs:element maxOccurs="unbounded" name="w"> <xs:complexType> <xs:sequence> <xs:element maxOccurs="unbounded" name="p" type="xs:unsignedByte" /> </xs:sequence> <xs:attribute name="wid" type="xs:unsignedByte" use="required" /> </xs:complexType> </xs:element> </xs:sequence> </xs:complexType> </xs:element> </xs:schema> and some data to go with it: <wi xmlns="http://www.example.com"> <w wid="1"> <p>28</p> <p>72</p> <p>125</p> </w> <w wid="4"> <p>89</p> </w> <w wid="5"> <p>11</p> </w> </wi> I need to search for multiple values in my xml column WordIndex either using OR or AND. What I'm doing is fairly rudimentary, since I'm a n00b in XQuery (taken from debug output, hence real values): with xmlnamespaces(default 'http://www.example.com') select m.Subject, m.MessageId, m.WordIndex.query(' let $dummy := 0 return <word_list> { for $w in /wi/w where $w/@wid=64 return <word wid="64" pos="{data($w/p)}"/> } { for $w in /wi/w where $w/@wid=70 return <word wid="70" pos="{data($w/p)}"/> } { for $w in /wi/w where $w/@wid=63 return <word wid="63" pos="{data($w/p)}"/> } </word_list> ') as WordPosition from Message as m -- more joins go here ... where -- more conditions go here ... and m.WordIndex.exist('/wi/w[@wid=64]') = 1 and m.WordIndex.exist('/wi/w[@wid=70]') = 1 and m.WordIndex.exist('/wi/w[@wid=63]') = 1 How can this be optimized?

  • How to call a JavaScript function from one frame to another in Chrome/Webkit with file protocol

    - by bambax
    I have developed an application that has a list of items in one frame; when one clicks on an item it does something in another frame (loads an image). This used to work fine in all browsers, including Chrome 3; now it still works fine in Firefox but in recent versions of Chrome (I believe since 4) it throws this error: Unsafe JavaScript attempt to access frame with URL (...) from frame with URL (...). Domains, protocols and ports must match. This is obviously a security "feature" but is it possible to get around it? Here is a simple test: index.html: <html> <frameset cols="50%,50%"> <frame src="left.html" name="left"/> <frame src="right.html" name="right"/> </frameset> </html> left.html: <html> <body> <a href="javascript:parent.right.test('hello');">click me</a> </body> </html> right.html: <html> <body> <script> function test(msg) { alert(msg); } </script> </body> </html> The above works in Firefox 3.6 and Chrome 3 but in Chrome 5 it throws the above error... Edit: added the @cols attribute to the frameset element in fact it works in Chrome if and only if the pages are served with the http protocol (and from the same domain) but my problem is when pages are local and served from a file:// protocol. Then it works in Firefox (all versions) and Chrome 3 but not Chrome 5 (I don't have Chrome 4 so I'm not shure about that specific version (and don't know if it's even possible to download a specific Chrome version?) -- but for Chrome 5 I'm very sure it doesn't work).
