• How to store user preferences? Cookie becomes bigger..

  - by ari

  My application (Asp.Net MVC) has great interaction with the user interface (jQuery/js). For example, setting various searches charts, moving the gadgets on the screen and more .. I of course want to keep all data for each user. So that data will be available from any page in the Dumaine and the user will accepts his preferences. Now I keep all data in a cookie because it did not seem logical asynchronous access to the server each time the user changes something and thet happens a lot.When the user logout from the application I save the cookie to the database. The problem is the cookie becomes very large. The thought that this huge cookie is attached to each server request makes me feel that my attitude is wrong. Another problem cookies have size limit. It varies from your browser but I definitely have been close to the border - my cookie easily become 4kb Is there another solution?

• XHtml Strict, Float: Center ?

  - by Axel Myers

  Hi everyone. I'm having hard time with Xhtml Strict 1.0 and Css. And I'm almost out of solutions. My Site Url: http://www.pro-turk.net/beta/ I made a jquery multilevel dropdown menu for my site. It looks like OK, but I have used inline-block property of css display attribute on navigation menu which is a part of css 2.1 and isn't supported by some browsers (including ie6 and ie7). I want to make #nav li elements block level elements, but to do this and having all of them in same line, the only way is using float in #nav li. But I want to center them in their parent (the menu bar). So I need something like float:center (I know it's pretty stupid and doesn't exist). But is there a way to include block level elements as children elements without linebreaks (I mean without making a block level element). Regards.

• How to organize Enterprise scale Composite Applications (CAG)

  - by David

  All QuickStarts and RI examples in the CAG documentation are good but I lack the more Enterprise scale examples. Let's say we have 40+ modules, each containing a Proxy,Facade,PresentationModel,Model and Views. Each module also makes calls to a Module-specific WCF service which is to be hosted in IIS or in a stand-alone console host. Our approach have been to include the UI-module, service-module and related tests into one solution so they can be developed and tested separately from other modules. My problem is how the hosting of the services should be done when the services are in separate modules and how to actually run the separate module together with the rest of the application-modules when I press F5. Is there a best practise for this? I guess it has been done before?

• WPF Dragging causes renderer to stop

  - by Cameron MacFarland

  I'm having a problem with my WPF app, where any sort of drag operation stops the UI from updating. The issue seems periodic, as in, the item drags, stops, drags again, stops, etc. in 2 second intervals. It's affecting all controls, including scroll bars. If checked this question as well as this one, and it doesn't seem to be caused by window transparencies. I'm running Win7 x64 with .NET 3.5sp1. Does anyone know what might be causing this, or a way of figuring out what might be causing this?

• jqueryUI: Drag element from dialog and drop onto main page?

  - by Seth Petry-Johnson

  I am trying to create a drag and drop system consisting of a workspace and a "palette". The workspace currently consists of re-orderable list items, and I want the palette to be a floating window from which I can drag items and add them to a specific position on the workspace. I am currently using the jqueryUI "sortable" plugin for the workspace and the jqueryUI "dialog" plugin for the palette. However, I cannot drag something out of the dialog and on to the main page. When I try, the item being dragged disappears as it crosses the boundary of the dialog (which makes sense). What can I change so that items will remain visible as I drag them out of the palette and allow me to drop them onto the main workspace? Alternatively, are there any jquery plugins that offer this sort of drag-n-drop palette as a primary feature?

• Authkit - deferring action for HTTP '401' response to client application

  - by jon

  Form, Redirect and Forward all send an unauthenticated user to a Form on a login page specified within an Authkit middleware application. I'd like to allow a client application to request a service via XHR and then present a custom 'client side' form if a HTTP status code of 401 is returned, which would then post to Authkit for authentication until valid authentication/authorization occured. Specifically, 1) a jquery $.get request might request a resource. 2) if an Authkit cookie check confirmed previous authorization the content would be returned. 3) if not I would like Authkit to simply return the '401 response' (and not redirect to another page, or return a form template) where a client side exception handler would notify the user and present an authentication form. Can Authkit work like this?

• Ajaxifying Struts2 application

  - by scotty

  I just started working on an application that is build on the Struts2 framework. I am coming from a .Net application with lot of Ajax features like dimming the rest of the site and show dialog box 'please wait while X is happening' ...auto complete and such other ajax features. I searched google for Ajax plugins for Struts2 but did not find anything that looks like it would be worth it. Is my only option to use jquery and its plugins? Is this a pattern that some of you have seen also? Hopefully Java applications are not dead soon because of its inability to cope with ajax...compared to .Net

• No Flash, How do i handle jcupload ?

  - by acidzombie24

  I am using http://www.jcupload.com/ (basic) to upload files. I am considering having a friend write a more custom version or to do magic with ajax; so the solution should be able to work without that. With jcupload i include css, a script and write <div id="jcupload_content"></div> in my html and i am done. Problem is, with no flash i get an object box. Instead i would like is an iframe or a html form to upload the file. How do i do this? Should i detect flash from javascript and overload the div myself if no flash is available? How do i detect if flash is available? with jquery i know i can write something like $('#jcupload_content').innerHtml = blah; How do i handle the flash part?

• Figuring out if overflow:auto would have been triggered on a div

  - by jerrygarciuh

  Hi folks, // Major edit, sorry in bed with back pain, screwed up post One of the ad agencies I code for had me set up an alternate scrolling solution because you know how designers hate things that just work but aren't beautiful. The scrolling solution is applied to divs with overflow:hidden and uses jQuery's scrollTo(). So, this is married in places to their CMS. What I have not been able to sort yet is how to hide the scrolling UI when overflow:auto would not have been triggered by the CMS content. The divs have set heights and widths. Can i detect hidden content? Or measure the div contents' height? Any ideas? TIA JG

• dojo datagrid will make the page "jump" when sorting is changed

  - by Select0r

  Hi, I have a Dojo Datagrid in one of my pages (which contains more content) and the following problem occurs: As soon as I click on a column header to change the sorting, the page will jump up as if I clicked on some HTML-anchor. Funny enough, the page jump will make the grid show only the first two rows after it jumped, instead of (e.g.) have the grid start at the top of the page after the jump, which is the expected behaviour if an anchor is used. The problem occurs in different browsers (tested: Firefox 3.6, Opera 10, IE6), so I guess it might be a Dojo-problem/-bug. Any ideas to make this annoying behaviour stop? Greetings, Select0r PS: this seems to describe a similar problem, only for JQuery (and unfortunately without a solution, too)

• Why does IE8 change flash callback function into object?

  - by Christian Hollbaum

  Hi Guys I have put 2 swf's (using swfobject 2) on the same website; One for playing a movie, and one for controlling the movie (I want to position them seperately, so they can't be in the same swf). I'm doing the communication between the two using javascript with jQuery, and externalcallback functions in both swf's. Everything is running smoothly on all browsers, but IE8. In IE8 I can only call the pause callback function in the control swf once. When it has been called it will not run properly the next time. After trying to debug what is happening live, using javascript's "type of" I have found that IE8 changes the callback function on the flash object from a function into an object when it has been triggered. Can anyone explain why this is happening? .. and maybe suggest how to avoid this? .. or change the object back to a function?

• How to know when a pop-down menu needs to be closed

  - by Pieter

  I'm experimenting with pop-down menus (inside floating DIVs). Making them appear with onmouseover attributes is no problem, but I'm not sure how I can make the menu close properly. I figured the best way to know when to close the menu is wait until the mouse is no longer hovering over the HTML element that called the menu or the menu itself, then wait one second, and then close the menu. Is my idea something that can be implemented, perhaps with some jQuery? Or is there a better and more efficient alternative?

• Dashcode and firefox compatibility

  - by nacho4d

  Hi all, I started to use Dashcode with a Safari Custom Project, my apps work fine, but StackLayout Object does not work in Firefox. I know Dashcode use many wekbit-specific things but is there any way I can get StackLayout object o work in Firefox? I would not mind losing some fancy stuff like transition-animations as long as my Views change. StackLayout also does not work in IE, but I think that is too much to expect from IE. lol. Any suggestions, ideas? Maybe jQuery or Dojo libraries can be used with DashCode in case webkit is not available?. in this case how can I do this? Thanks.

• asp.net MVC Partial Views how to initialise javascript

  - by Simon G

  Hi, I have an edit form that uses an ajax form to submit to the controller. Depending on the data submitted I redirect the user to one of two pages (by returning a partial view). Both pages rely on javascript/jquery and neither use anything common between the pages. What is the best way to initialise these javascripts on each page? I know there is the AjaxOption OnComplete but both pages are quite dynamic depending on the Model passed and I would rather keep the javascript for both pages seperate rather than having a common method. Thanks

• IE7 Animated GIF Appears as a Static Image?

  - by Abs

  Hello all, After a button is clicked to start a process on my web app, I show a small loading gif (animated) that rotates to indicate to the user something is happening. I put the gif img in place of the button like this using JQuery: $('#btn_holder').html('<img src="images/loading2.gif" style="margin-left:40px; margin-top:7px;" />'); This works great in all browsers (Firefox, IE8, Chrome) except IE7 on a windows server 2003. In IE, the gif appears but it is not animated. What's going on with IE7? How can I test what the problem is? Thanks all

• Displaying large file in JTextArea.

  - by Sathish Gopal

  Hi All, I'm currently working in Swing UI Assignment. This work involves showing large file content in JTextArea. The file size can be as large as 2 GB. My initial idea is to lazily load content from the file, say 1 MB of content will be shown to the user. As the user scrolls i will retrieve the next 1 MB of content to be shown. All these operation will be happening in background thread (Swing Worker). I looked at the JTextArea API, the method insert takes String and int(position of the insert) as the parameter. This will suffice, but i'm worried about performance, because the content (1 MB at a time) retrieved will have to be converted to String object. Is there any other work around or any other alternative/better solution for this.

• PerformSelectorInBackground leaking on device

  - by Oysio

  While it seems to not pose a problem on the simulator, using performSelectorInBackground on the device causes memory leaks. Or at least that's what Instruments indicates. Looking at the code I don't have a single clue what the cause could be. I tried to strip the affected code to a bare minimum but still strangely Instruments keeps showing a leak every time this piece of code is executed. Anything unusual going on here? //In viewcontrollerA: -(void)mainLoop { [self.viewControllerB performSelectorInBackground:@selector(calculateTotals) withObject:nil]; //This gives the same problem //[NSThread detachNewThreadSelector:@selector(calculateTotals) toTarget:self.viewControllerB withObject:nil]; //UI stuff ... } //viewControllerB: -(void)calculateTotals { NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; //Heavy calculations ... [pool release]; }

• How do I get all values from a listbox that are not selected in ASP.NET MVC

  - by Nick Reeve

  Hello, I have a form that (amongst other things) contains 2 multi-select listboxes. Basically you can add items to the one on the right from the full list of items on the left using some add/remove buttons. The problem is that I cannot see a way of picking up the contents of the listbox when posting back to the controller. I have followed this example: http://ittecture.wordpress.com/2009/04/30/tip-of-the-day-198-asp-net-mvc-listbox-controls/ This works fine if you have actually selected the items in the listbox before posting. That's not really the way I think this UI should behave though. Hope that makes sense, Nick

• Background settings for a JDesktopPane

  - by EricR

  I'm using a self-made DesktopPaneUI for a JDesktopPane, I've written the proper methods for the class, and I'm running into trouble. When I resize the JDesktopPane, the background image doesn't resize with the frame. The image appears to be clipped at the size it was when the window initially opened. I'm giving it an image larger than the window, and I'm still having this problem. Here's my method call inside the constructor of my desktopUI class. super(); this.background = javax.imageio.ImageIO.read(new File(fileName)); Is there a way I can change my main class where I set the UI, or the myDesktopPaneUI class such that the background still fills the window when the JDesktopPane changes size? setUI(new myDesktopPaneUI("media/bg.jpg"));

• Save a camera photo with an overlayed image - iphone SDK

  - by user157733

  I think this should be simple but I am having some difficulty implementing it. I take a photo from the camera, the user can then move and scale it. They then choose "use" and they get a preview of their image. Now what I want to do is overlay an image on top of this preview image - which is also ok. But the part I am having difficulty is then I want to save the photo taken WITH the image that is over it into the library. I just have a UIView with my overlay image about the UIView where my camera photo is previewed. I guess I just need to take a screen capture of these? I don't want to loose resolution OR end up with my UI buttons etc in the final image. Any suggestions or links would be really useful. Thanks :-)

• asp.net form validation. Server-side or client-side

  - by Jeroen

  Here's (i think) an interesting question. With AJAX more and more common i feel more and more like doing all form validation server-side. Picture a registration form pre-AJAX. You have all your validation client-side using the common asp validation controls and validation summery...except...checking username availability, check emailadress availability, captcha and what not. So you end up with 2 kinds of validation and so presenting the user with 2 different UI's at 2 different moments. 2 words come to my mind. Ugly. Inconsistent. So here's the question. Why not do all the validation server-side (using AJAX or not). (I'm not using JQuery yet, should i?)

• How to make IE 9 Standards Mode the default mode?

  - by Evik James

  I have a web site that works perfectly fine in IE9 when compatibility mode is turned OFF (the compatibility symbol is gray). When compatibility mode is turned on (blue), the jQuery doesn't work at all. I have added the following tag to the site to tell the browser that compatibility mode should NOT be used. <meta http-equiv="X-UA-Compatible" content="IE=Edge" > I have the doctype as this: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> Still, the browser doesn't seem to default to standard mode and the user must manually ensure that they are NOT in compatibility mode. Can I disable IE 9 Compatibility Mode? Have I done what I need to do to disable IE 9 Compatibility Mode? Can the user always override IE 9 Standards Mode?

• Disabling a link tag using JavaScript on my printable page

  - by Fiona Holder

  I have a script that creates a printable page by copying the HTML across and then doing some manipulation, such as disabling the buttons on the page, on page load. I also want to disable the links on the page. I don't really mind if they look like links still as long as they don't do anything, and don't give any JavaScript errors! The anchor tag doesn't seem to have a disabled attribute... Unfortunately, I can't use jQuery, so JavaScript only please! Edit: I want to disable the links, buttons etc on the page so that when the 'printable page' opens in another window, the user cannot mess with it by clicking buttons or links. I want it to essentially be a 'frozen snapshot' of the page that they want to print.
