• several jquery ui theme switcher problems (cookie, different themes for different pages, etc.)

  - by powerboy

  I just try putting the jquery-ui theme switcher on my website. Seems that there are some problems: Cookie does not work. When I close the browser and reopen the webpage, the default theme will load instead of the one selected before. The selected theme is valid for current page only. If jumping to another page, it will load the default. I want to select once and apply to all pages. There is a flash of the default theme before the selected theme get loaded. Anyone know an easy way deal with these problems? I know I can implement my own cookie solution based on that theme switcher, but I was so surprised that the author did not provide options to do these.

• asp.net: moving from session variables to cookies

  - by P a u l

  My forms are losing session variables on shared hosting very quickly (webhost4life), and I think I want to replace them with cookies. Does the following look reasonable for tracking an ID from form to form: if(Request.Cookies["currentForm"] == null) return; projectID = new Guid(Request.Cookies["currentForm"]["selectedProjectID"]); Response.Cookies["currentForm"]["selectedProjectID"] = Request.Cookies["currentForm"]["selectedProjectID"]; Note that I am setting the Response cookie in all the forms after I read the Request cookie. Is this necessary? Do the Request cookies copy to the Response automatically? I'm setting no properties on the cookies and create them this way: Response.Cookies["currentForm"]["selectedProjectID"] = someGuid.ToString(); The intention is that these are temporary header cookies, not persisted on the client any longer than the browser session. I ask this since I don't often write websites.

• Image visualization with canvas. How to resize them?

  - by Luca Matteis

  I'm building a website photo gallery for a friend. Images are loaded as simple DOM image objects (<img src="" />), and the size of these images is based on the browser size. So I resize them with CSS. This isn't an optimal solution since CSS resizing seems to change the quality of the image and pixelate it quite a bit. I was thinking of rendering the image with canvas and then resize it with that so that the quality remains effective, but I can't find any info about this online. Any ideas?

• Are AJAX calls to a sub-domain considered Cross Site Scripting?

  - by AaronPresley

  I have Server A (www.example.com) sending information to Server B. I can only have HTML / JS on Server A (and have to do the "crunching" on Server B) so I'm trying to send form data via AJAX (trying to avoid a form post to Server B - don't ask). Obviously doing an AJAX call cross-domain is considered XSS and a big no-no, but if I were to put Server B in a subdomain (sub.example.com), would that be considered okay? How are cross-domain errors detected? Does the browser look up DNS records? IP address? Thanks in advance for you help.

• Why exactly is server side HTML rendering faster than client side?

  - by mvbl fst

  I am working on a large web site, and we're moving a lot of functionality to the client side (Require.js, Backbone and Handlebars stack). There are even discussions about possibly moving all rendering to the client side. But reading some articles, especially ones about Twitter moving away from client side rendering, which mention that server side is faster / more reliable, I begin to have questions. I don't understand how rendering fairly simple HTML widgets in JS from JSON and templates is a contemporary browser on a dual core CPU with 4-8 GB RAM is any slower than making dozens of includes in your server side app. Are there any actual real life benchmarking figures regarding this? Also, it seems like parsing HTML templates by server side templating engines can't be any faster than rendering same HTML code from a Handlebars template, especially if this is a precomp JS function?

• How to model localized items

  - by tweir

  I'm currently designing a e-commerce solution. One of the primary requirements is for the store to support localized item details. The same store must be able to support multiple languages via the user's language selection and/or browser preference. I have two tables: Item (id, sku, price, ...) ItemDetails (item_id, language, title, ...) For each Item, there will be multiple rows corresponding to the item, where the (item_id,language) pair will be unique. I would like to model this as: class Item { public string sku; public double price; public ItemDetails Details; } Based on the user's session, I would like the items returned to have the Details object corresponds to the user's selected language (from their session). What are some approaches for representing this?

• How do I bind a click to an anchor without a framework (javascript)

  - by Stomped

  I know this is easily done in jQuery or any other framework, but that's not really the point. How do I go about 'properly' binding a click event in pure javascript? I know how to do it inline (I know this is terrible) <a href="doc.html" onclick="myFunc(); return false">click here</a> and this causes my javascript to execute for a JS enabled browser, and the link to behave normally for those without javascript? Now, how do I do the same thing in a non-inline manner?

• Returning a 1x1 .gif as a response in Rails

  - by Avishai

  Hi, I'm building a Rails app that does conversion tracking on outside sites. I'd like to allow users to paste an image tag in their conversion pages (like AdWords), and whenever that image is requested, a conversion registers in my app. respond_to do |format| if @conversion.save flash[:notice] = 'Conversion was successfully created.' format.html { redirect_to(@conversion) } format.xml { render :xml => @conversion, :status => :created, :location => @conversion } format.js { render :json => @conversion, :status => :created } format.gif { head :status => :ok } else format.html { render :action => "new" } format.xml { render :xml => @conversion.errors, :status => :unprocessable_entity } end end This way, the browser gets a non-existent .gif image. Is there a better way to do this?

• html-embedded php code not executing when hosted on iis

  - by Jack

  <HTML> <HEAD> <META NAME="GENERATOR" Content="Microsoft Visual Studio .NET 7.1"> <TITLE></TITLE> </HEAD> <BODY> <?php echo '<p>Hello World</p>'; ?> </BODY> </HTML> When I run the above code in a browser, firefox renders it like this: Hello World '; ?> I am doing my coding in Windows XP/IIS 5.1. I have PHP set up correctly because I have no problem running .php files. The problem, it seems to me, is that IIS can't render php code embedded inside html. Does anyone know how to fix this problem or should i switch to Apache?

• What workflow should I use for JavaScript editing?

  - by Patrick

  Warning: I have very little JavsScript experience. In my past programming experience, I usually have a standalone interpreter/compiler, a text editor and a command line to compile/run my software or my tests (I love test driven development). I really like it this way, since I have the feeling of being in complete control over the tools. However, editing JavaScript I need to put statements in a text file , open my web browser and click on reload. I don't feel comfortable with it, as I cannot really see what is going on (besides some alert boxes). Can you suggest me (I'm on a Mac) another workflow? Perhaps with a debugger? Is there a standalone JavaScript interpreter?

• SSRS 2008 Report.GetDefaultPageSettings returns incorrect information

  - by jhale

  I have an application that retrieves a report from SSRS 2008 and prints it automatically. This works except it always prints the report in Letter/Portrait. This particular report is Letter/Landscape. I have tracked the problem down to when calling the Report.GetDefaultPageSettings() function for this report, it returns PaperSize.Height = 1100 and PaperSize.Width = 850. I even modified the report to a custom size of 11" x 8.4" and it still returns 850 for the width. I cannot get this to print correctly when it renders the image incorrectly based on these settings. The report prints correctly when accessed by a web browser. It is only when I am trying to automatically print it that the issue appears.

• Display indented XML code within a HTML page

  - by Efrain

  I have a programmatically created HTML document on which I would like to show some XML-code, fully formatted with line breaks and tabulators. That is, it should look like if you drag an xml file without a xml-stylesheet directly onto your browser (most browsers do some kind of xml-rendering with some default style sheet). Now, I can of course escape all the characters (like <>, tab and newline) and do the indenting myself (using css styles, for example), but I was wondering whether I couldn't re-use some 'default' xml-stylesheet from somewhere. Preferrably also one that has some javascript node-folding, too. Do you know such a stylesheet/xslt? Or would you suggest another way to achieve this? I'm using C#. PS: I tried to use the XmlNotepad.DefaultSS.xslt from Microsoft's XmlNotepad, but I couldn't really get that working. :T

• Problem loading a contents URL into a string

  - by bebeTech

  I've been using this method for a few weeks now as suggested on my previous question and the app now keeps crashing with a Protocol 443 error - something about unable to resolve the address. Worked fine when first installed and then just stopped. The same with on the device itself, worked fine until this morning and now the same issue?? Nothing wrong with the URL as I can still load in a browser. If I leave it for a couple of days it starts working again?? Is there a more effecient way of using the Http POST and GET functions? All I am trying to do is perform a login and save the resulting page to a string. Is there a more Android friendly way?

• HTML img scaling

  - by rwallace

  I'm trying to display some large images with HTML img tags. At the moment they go off the edge of the screen; how can I scale them to stay within the browser window? Or in the likely event that this is not possible, is it possible to at least say "display this image at 50% of its normal width and height"? The width and height attributes distort the image -- as far as I can tell, this is because they refer to whatever attributes the container may end up with, which will be unrelated to the image. I can't specify pixels because I have to deal with a large collection of images each with a different pixel size. Max-width doesn't work.

• Visualizing branch topology in git

  - by Benjol

  I'm playing with git in isolation on my own machine, and even like that I find it difficult to maintain a mental model of all my branches and commits. I know I can do a git log to see the commit history from where I am, but is there a way to see the entire branch topography, something like these ascii maps that seem to be used everywhere for explaining branches? .-A---M---N---O---P / / / / / I B C D E \ / / / / `-------------' It just feels like someone coming along and trying to pick up my repository would have difficulty working out exactly what was going on. I guess I'm influenced by AccuRev's stream browser...

• Post wall message on facebook account

  - by Zeroshade

  Hello, I am trying to implement some functionality in a blackberry app, that I saw in other application. Basically it's a window that has a message, and a Facebook icon. When you click on the icon it launches a new window, this window asks the user for permissions(user and password), and then the message is posted in the user's wall. So my question is how can I replicate that?. I have been looking at the graph api, but I just can't figure out how to do all of this in one step. I mean just typing the url in the browser, and some post data. Thanks a lot.

• Referencing a different project in the same assembly, different namespaces

  - by Redburn

  I have two projects : Menu and Module and they are both in the same namespace foobar. I am currently referencing the module project from the Menu project to open up certain controls on a tab control in my menu. However I need to launch a new control from one of my controls which is located in the Module project. When I try referencing the menu project, it does not show up in my intellisense when I try to reference it with a using. Am I doing something wrong logically here? Here is an example of what it is : Project Menu Public Void LaunchWPFControl(string pHeader,string pPath) { //Code goes here to launch a WPF control in the browser } Project Module //What I would love to do but doesn't work Using Menu; ... ... ... private void dgModule_MouseDoubleClick(object sender, MouseButtonEventArgs e) { Menu.LaunchWPFControl("Accounts","AccountsControl"); }

• expiring image assets referenced from stylesheets

  - by crankharder

  So rails appends timestamps to CSS, JS and image files: image_tag 'foo.png' => <img src="foo.png?123123123123' /> # or somethin like that ...which is really useful for doing far-future expiration, etc. with Apache's help. But what about images referenced from stylesheets? They don't get an appended timestamp. So it seems to me that it's entirely possible to update one of those images, redeploy, and then not see the file change because the browser doesn't think it's been updated. Unless I'm missing something. If I'm not, is there a decent solution to this problem?

• Are your redirects HTTP compliant (absolute URI)?

  - by webbiedave

  In the Hypertext Transfer Protocol 1.1 spec, it states for the Location header: The field value consists of a single absolute URI. Location = "Location" ":" absoluteURI An example is: Location: http://www.w3.org/pub/WWW/People.html I have coded many an app that doesn't include the scheme and domain (i.e., /thankyou/) and every browser I've ever tested with redirects correctly. I'm wondering if it's imperative to go back and change all my redirect code or just ignore this part of the spec. Have many of you produced code that doesn't comply and will you go back and change it? Or will you just trust that clients will continue to resolve them well into the future? (going forward I will certainly adhere to this)
