  • Cross-browser curved borders

    - by Gandalf StormCrow
    What is the best way to achieve cross-browser(ff,ie6,chrome,opera,safari) curved corners on a div. I found this article http://jonraasch.com/blog/css-rounded-corners-in-all-browsers and I've followed instructions step by step multiple times, here is my css : #content_wrapper{ -moz-border-radius:25px 25px 25px 25px; -webkit-border-radius: 25px; -khtml-border-radius: 25px; border-radius: 25px; background-color:#F2DADC; border:25px solid #ECD3D5; height:780px; opacity:0.7; width:747px; margin:0px auto; position:relative; display:block; zoom:1; } <!--[if lte IE 8]> <style> #content_wrapper{ behavior: url(template/css/border-radius.htc); border-radius: 20px; } </style> <![endif]--> Can somebody point me what am I doing wrong or is there a better way to achieve the same effect, its working in all browsers except in IE

  • drop down menu will not display outside containing div in IE7..

    - by playahabana
    I am tearing my hair out over this, I have a dropdown menu using CSS and jQuery (thanks to Soh Tanaka) and it works perfectly in Firefox, Safari, Google chrome and I.E. 8, but in IE 7 it will not drop down outside the 'Banner div'. It drops below the nav div however. I have moved the nav div higher in the banner the result is the same, menu drops until it reaches the border of the banner div and then vanishes.... Below is the css. This is my first website and I have some limited understanding of what I am doing. The drop down menu includes transparent png's as links (I know, I know...but it's what the Boss wants...) please could someone take a quick scan at the below CSS and let me know what is wroong? Is this some form of the IE z-index bug? i have tried all different combinations of z-index and still I can't get a different result. . The html is below as well. Thankyou in advance #banner { position: relative; width: 62.5em; height: 12em; background-color: #46280A; background-image: url('images/includes/banner2.jpg'); background-repeat: no-repeat; background-position: center; -moz-box-shadow: -4px 6px 8px #000; -webkit-box-shadow: -4px 6px 8px #000; box-shadow: -4px 6px 8px #000; /* For IE 8 */ -ms-filter: "progid:DXImageTransform.Microsoft.Shadow(Strength=8, Direction=225, Color='#000000')"; /* For IE 5.5 - 7 */ filter: progid:DXImageTransform.Microsoft.Shadow(Strength=8, Direction=225, Color='#000000'); z-index: 1; } /*------------------------------------SCROLLER---------------------------------------------*/ #headlines{ position: absolute; top: 1.3em; right: 2.75em; overflow: hidden; height: 2.5em; width: 24em; background-color: #000000; display: block; z-index: 3; } #news{ position: relative; height: 3.1em; line-height: 2.5em; font-size: 0.8em color: #FFFF99; white-space: nowrap; overflow: hidden; font-family: Georgia,Arial; } #scrollerglass{ position: absolute; top: 0.95em; right: 2em; height: 52px; width: 410px; border: none; padding: 0.2em 0em 0em 0em; line-height: 0.7em; text-align: center; background-image: url('images/includes/scrollerglass.png'); background-color: transparent; background-repeat: no-repeat; background-position: center; opacity: 20; z-index: 10; } #scrollerglass a i { visibility: hiddn ; } /-------------------------------------NAVIGATION-----------------------------------------/ #nav { position: absolute; top: 5.8em; left: 0.2em; font-family: trebuchet, sans-serif; font-size: 1em; line-height: 3.75em; text-align: center; color: #FFFF00; z-index: 3; } ul.navlist { list-style: none; padding: 0em; margin: 1em; float: left; width: 62.5em; background: transparent; font-size: 1em; } ul.navlist li { position: relative; /*--Declare X and Y axis base for sub navigation--*/ float: left; margin: 0em 1.4em; padding: 0em 0.7em 0em 0em; z-index: 1; } ul.navlist li a{ display: block; text-decoration: none; float: left; border: 0px solid; } ul.navlist li img{ border: 0px solid; } ul.navlist li span { trigger styles--*/ width: 1.2em; height: 5.25em; float: left; background: url(images/links/downlogo.png) no-repeat center top; } ul.navlist li span.subhover { background-position: center bottom; cursor: pointer; } ul.navlist li ul.navdrop { list-style: none; position: absolute; float: left; top: 5.3em; left: -2.4em; height: 15.0em; width: 11.25em; margin: 0; padding: 0.5em 0em 0em 0em; display: none; background-position: center; background-image: url('images/includes/slider.jpg'); background-color: transparent; background-repeat: no-repeat; -moz-box-shadow: -4px 6px 8px #000; -webkit-box-shadow: -4px 6px 8px #000; box-shadow: -4px 6px 8px #000; /* For IE 8 */ -ms-filter: "progid:DXImageTransform.Microsoft.Shadow(Strength=8, Direction=225, Color='#000000')"; /* For IE 5.5 - 7 */ filter: progid:DXImageTransform.Microsoft.Shadow(Strength=8, Direction=225, Color='#000000'); z-index:1; } ul.navlist li ul.navdrop li{ margin: 0em 2.3em 0em 0em; padding: 1em 0em 0em 0em; width: 8em; clear: both; } html ul.navlist li ul.navdrop li a { border: 0px solid; width: 11.25em; } html ul.navlist li ul.navdrop li a:hover { background: transparent; } <div id="banner"> <div id="headlines"> <div id="news"> Whatever we want to promote </div> </div> <div id="scrollerglass"> <a href="vintagecigars.php"> <i>------s-c-r-o-l-l-e-r - - - -l-i-n-k-s--------<br /> <br>------s-c-r-o-l-l-e-r - - - -l-i-n-k-s------</i></a> </div> <div id="nav"> <ul class="navmenu"> <li><a href="index.php"><img src="images/links/home.png" alt="Home" ></a></li> <li><a href="ourbar.php"><img src="images/links/ourbar.png" alt="Our Bar" ></a> <ul class="navdrop"> <li ><a href="ourcocktails.php"><img src="images/links/cockteles.png" alt="Our Cocktails" ></a></li> <li ><a href="celebrate.php"><img src="images/links/celebrate.png" alt="Celebrate in Style" ></a></li> </ul> </li> <li><a href="ourcigars.php"><img src="images/links/ourcigars.png" alt="Our Cigars" ></a> <ul class="navdrop"> <li ><a href="edicioneslimitadas.php"><img src="images/links/edicioneslimitadas.png" alt="Edition Limitadas" ></a></li> <li ><a href="cigartasting.php"><img src="images/links/cigartasting.png" alt="Cigar Tastings" ></a></li> </ul> </li> <li><a href="personalroller.php"><img src="images/links/personalcigar.png" alt="Personal Cigar Roller" ></a></li> <li><a href="galleryentrance.php"><img src="images/links/photogallery.png" alt="Photo Gallery" ></a></li> <li><a href="contactus.php"><img src="images/links/contactus.png" alt="Contact Us" ></a></li> </ul></div></div><!--end banner-->

  • Best ways to format LINQ queries.

    - by Aren B
    Before you ignore / vote-to-close this question, I consider this a valid question to ask because code clarity is an important topic of discussion, it's essential to writing maintainable code and I would greatly appreciate answers from those who have come across this before. I've recently run into this problem, LINQ queries can get pretty nasty real quick because of the large amount of nesting. Below are some examples of the differences in formatting that I've come up with (for the same relatively non-complex query) No Formatting var allInventory = system.InventorySources.Select(src => new { Inventory = src.Value.GetInventory(product.OriginalProductId, true), Region = src.Value.Region }).GroupBy(i => i.Region, i => i.Inventory); Elevated Formatting var allInventory = system.InventorySources .Select(src => new { Inventory = src.Value.GetInventory(product.OriginalProductId, true), Region = src.Value.Region }) .GroupBy( i => i.Region, i => i.Inventory); Block Formatting var allInventory = system.InventorySources .Select( src => new { Inventory = src.Value.GetInventory(product.OriginalProductId, true), Region = src.Value.Region }) .GroupBy( i => i.Region, i => i.Inventory ); List Formatting var allInventory = system.InventorySources .Select(src => new { Inventory = src.Value.GetInventory(product.OriginalProductId, true), Region = src.Value.Region }) .GroupBy(i => i.Region, i => i.Inventory); I want to come up with a standard for linq formatting so that it maximizes readability & understanding and looks clean and professional. So far I can't decide so I turn the question to the professionals here.

  • NULL pointer dereference in swiotlb_unmap_sg_attrs() on disk IO

    - by Inductiveload
    I'm getting an error I really don't understand when reading or writing files using a PCIe block device driver. I seem to be hitting an issue in swiotlb_unmap_sg_attrs(), which appears to be doing a NULL dereference of the sg pointer, but I don't know where this is coming from, as the only scatterlist I use myself is allocated as part of the device info structure and persists as long as the driver does. There is a stacktrace to go with the problem. It tends to vary a bit in exact details, but it always crashes in swiotlb_unmap_sq_attrs(). I think it's likely I have a locking issue, as I am not sure how to handle the locks around the IO functions. The lock is already held when the request function is called, I release it before the IO functions themselves are called, as they need an (MSI) IRQ to complete. The IRQ handler updates a "status" value, which the IO function is waiting for. When the IO function returns, I then take the lock back up and return to request queue handling. The crash happens in blk_fetch_request() during the following: if (!__blk_end_request(req, res, bytes)){ printk(KERN_ERR "%s next request\n", DRIVER_NAME); req = blk_fetch_request(q); } else { printk(KERN_ERR "%s same request\n", DRIVER_NAME); } where bytes is updated by the request handler to be the total length of IO (summed length of each scatter-gather segment).

  • Only first word of two strings gets added to db

    - by dkgeld
    When trying to add words to a database via php, only the first word of both strings gets added. I send the text via this code: public void sendTextToDB() { valcom = editText1.getText().toString(); valnm = editText2.getText().toString(); t = new Thread() { public void run() { try { url = new URL("http://10.0.2.2/HB/hikebuddy.php?function=setcomm&comment="+valcom+"&name="+valnm); h = (HttpURLConnection)url.openConnection(); if( h.getResponseCode() == HttpURLConnection.HTTP_OK){ is = h.getInputStream(); }else{ is = h.getErrorStream(); } h.disconnect(); } catch (Exception e) { // TODO Auto-generated catch block e.printStackTrace(); Log.d("Test", "CONNECTION FAILED 1"); } } }; t.start(); } When tested with spaces and commas etc. in a browser, the php function adds all text. The strings also return the full value when inserted into a dialog. How do I fix this? Thank you.

  • EUpdateError exception not recognized when raised in TDatasetProvider.OnUpdateError. Why?

    - by max
    When I re-throw a EUpdateError exception in the TDatasetProvider.OnUpdateError event, it is not recognized as EUpdateError exception in the catch block. It's only recognized as base Excption. try ... //calls the TDatasetPorvider.OnUpdateError event. myClientDataSet.ApplyUpdates(0); ... except on ex: EUpdateError do begin //never goes here //Evaluate ex.ErrorCode end; on ex: Exception do begin //always goes here //the expression (ex is EUpdateError) returns false; end; end; Hiere is the corresponding .OnUpdateError implementaion: procedure MyDataModule.MyDatasetProviderOnUpdateError(..;E: EUpdateError;...); beign //Here, the expression (E is EUpdateException) returns true; raise E; end; The exception is re-thrown, but as it seems the EUpdateError is transformed into a plain base Execption. Does anybody know, why the class type get lost? I would need that type in order to check the .ErrorCode to know what went wrong and to prepare the proper user message.

  • How To Select First Ancestor That Matches A Selector?

    - by Zach
    General: How can I select the first matching ancestor of an element in jQuery? Example: Take this HTML block <table> <tbody> <tr> <td> <a href="#" class="remove">Remove</a> </td> </tr> <tr> <td> <a href="#" class="remove">Remove</a> </td> </tr> </tbody> </table> I can remove a row in the table by clicking "Remove" using this jQuery code: $('.remove').click(function(){ $(this).parent().parent().hide(); return false; }); This works, but it's pretty fragile. If someone puts the <a> into a <div>, for example, it would break. Is there a selector syntax in jQuery that follows this logic: "Here's an element, now find the closest ancestor that matches some selection criteria and return it" Thanks

  • Howto display or view encrypted data in encrypted form?

    - by Brian Gianforcaro
    In the Wikipedia Article on Block Cipher Modes they have a neat little diagram of an unencrypted image, the same image encrypted using ECB mode and another version of the same image encrypted using another method. At university I have developed my own implementation of DES (you can find it here) and we must demo our implementation in a presentation. I would like to display a similar example as shown above using our implementation. However most image files have header blocks associated with them, which when encrypting the file with our implementation, also get encrypted. So when you go to open them in an image viewer, they are assumed to be corrupted and can't be viewed. I was wondering if anybody new of a simple header-less image format which we could use to display these? Or if anyone had any idea's as to how the original creator of the images above achieved the above result? Any help would be appreciated, Thanks Note: I realise rolling your own cryptography library is stupid, and DES is considered broken, and ECB mode is very flawed for any useful cryptography, this was purely an academic exercise for school. So please, no lectures, I know the drill.

  • How to store <TR> id value in array, when I toggle?

    - by James123
    I am toggling 'tr.subCategory1'and its siblings .RegText. at the same time I am trying to store its ids in the array like this list_Visible_Ids[$(this).attr('id')] = $(this).css('display') != 'none' ? 1 : null; (When I collapsed I need store 'null' in array at its id place, If I expand I need store I need store 1 at its id place). But everytime alert($(this).css('display')) showing block. How can I handle this?. So When I collapsed or expanded it is storing 1 only. $(document).ready(function() { $('tr[@class^=RegText]').hide().children('td'); list_Visible_Ids = []; var idsString, idsArray; idsString = $('#myVisibleRows').val(); idsArray = idsString.split(','); $.each(idsArray, function() { if (this != "" || this != null) { $('#' + this).siblings('.RegText').toggle(); list_Visible_Ids[this] = 1; } }); $('tr.subCategory1') .css("cursor", "pointer") .attr("title", "Click to expand/collapse") .click(function() { $(this).siblings('.RegText').toggle(); $(this).siblings('.VolumeRegText').toggle(); //alert($(this).css('display')) list_Visible_Ids[$(this).attr('id')] = $(this).css('display') != 'none' ? 1 : null; }); $('#form1').submit(function() { idsString = ''; for (var index in list_Visible_Ids) { idsString += (idsString != '' ? ',' : '') + index; } $('#myVisibleRows').val(idsString); form1.submit(); }); });

  • Fade in an HTML element with raw javascript over 500 miliseconds.

    - by Juan C. Rois
    Hello everybody, Once again I find myself stuck by something that I just don't understand. Any help would be appreciated. I'm working on a modal window, you click something and the background is masked and a modal window shows some content. I have a div with "display:none" and "opacity:0", and when the user triggers the modal, this div will overlay everything and have certain transparency to it. In my mind, what I need to do is: Set the opacity Perform a "for" loop that will check if the opacity is less than the desired value. Inside this loop, perform a "setInterval" to gradually increment the value of the opacity until it reaches the desired value. When the desired value has been reached, perform an "if" statement to "clearInterval". My code so far is as follows: var showMask = document.getElementById('mask'); function fireModal(){ showMask.style.opacity = 0; showMask.style.display = 'block'; var getCurrentOpacity = showMask.style.opacity; var increaseOpacity = 0.02; var finalOpacity = 0.7; var intervalIncrement = 20; var timeLapse = 500; function fadeIn(){ for(var i = getCurrentOpacity; i < finalOpacity; i++){ setInterval(function(){ showMask.style.opacity = i; }, intervalIncrement) } if(getCurrentOpacity == finalOpacity){ clearInterval(); } } fadeIn(); } As you all can guess, this is not working, all it does is set the opacity to "1" without gradually fade it in. Thanks in advance for your help.

  • Randomizing Div tags using Java Script

    - by Andrew McNeil
    I've looked around and have been able to find a piece of code that does the job but it doesn't work for all of my tags. I have a total of 8 Div tags that I want to randomize and this piece of code only allows me to randomize 7 of them. If I replace the 7 with an 8 it just shows everything in order. I don't work with Javascript very often and have hit a road block. Any help is greatly appreciated. <script type="text/javascript"> $(document).ready(function() { $(".workPiece").hide(); var elements = $(".workPiece"); var elementCount = elements.size(); var elementsToShow = 7; var alreadyChoosen = ","; var i = 0; while (i < elementsToShow) { var rand = Math.floor(Math.random() * elementCount); if (alreadyChoosen.indexOf("," + rand + ",") < 0) { alreadyChoosen += rand + ","; elements.eq(rand).show(); ++i; } } }); </script>

  • Rails exit controller after rendering

    - by codysehl
    I have an action in my controller that I am having trouble with. This is my first rails app, so I'm not sure of the best practices surrounding rails. I have a model called Group and a few actions that go in it's controller. I have written a test that should cause the controller to render an error in JSON because of an invalid Group ID. Instead of rendering and exiting, it looks like the controller is rendering and continuing to execute. Test test 'should not remove group because of invalid group id' do post(:remove, {'group_id' => '3333'}) response = JSON.parse(@response.body) assert_response :success assert_equal 'Success', response['message'] end Controller action # Post remove # group_id def remove if((@group = Group.find_by_id(params[:group_id])) == nil) render :json => { :message => "group_id not found" } end @group.destroy if(!Group.exists?(@group)) render :json => { :message => "Success" } else render :json => { :errors => @group.errors.full_messages } end end In the controller, the first if statement executes: render :json => { :message => "group_id not found" } but @group.destroy is still being executed. This seems counter-intuitive to me, I would think that the render method should exit the controller. Why is the controller not exiting after render is called? The purpose of this block of code is to recover gracefully when no record can be found with the passed in ID. Is this the correct way of doing something like this?

  • Is there a quality, file-size, or other benefit to JPEG sizes being multiples of 8px or 16px?

    - by davebug
    The JPEG compression encoding process splits a given image into blocks of 8x8 pixels, working with these blocks in future lossy and lossless compressions. [source] It is also mentioned that if the image is a multiple 1MCU block (defined as a Minimum Coded Unit, 'usually 16 pixels in both directions') that lossless alterations to a JPEG can be performed. [source] I am working with product images and would like to know both if, and how much benefit can be derived from using multiples of 16 in my final image size (say, using an image with size 480px by 360px) vs. a non-multiple of 16 (such as 484x362). In this example I am not interested in further alterations, editing, or recompression of the final image. To try to get closer to a specific answer where I know there must be largely generalities: Given a 480x360 image that is 64k and saved at maximum quality in Photoshop [example]: Can I expect any quality loss from an image that is 484x362 What amount of file size addition can I expect (for this example, the additional space would be white pixels) Are there any other disadvantages to growing larger than the 8px grid? I know it's arbitrary to use that specific example, but it would still be helpful (for me and potentially any others pondering an image size) to understand what level of compromise I'd be dealing with in breaking the non-8px grid. The key issue here is a debate I've had is whether 8-pixel divisible images are higher quality than images that are not divisible by 8-pixels.

  • initalizing two pointers to same value in "for" loop

    - by MCP
    I'm working with a linked list and am trying to initalize two pointers equal to the "first"/"head" pointer. I'm trying to do this cleanly in a "for" loop. The point of all this being so that I can run two pointers through the linked list, one right behind the other (so that I can modify as needed)... Something like: //listHead = main pointer to the linked list for (blockT *front, *back = listHead; front != NULL; front = front->next) //...// back = back->next; The idea being I can increment front early so that it's one ahead, doing the work, and not incrementing "back" until the bottom of the code block in case I need to backup in order to modify the linked list... Regardless as to the "why" of this, in addition to the above I've tried: for (blockT *front = *back = listHead; /.../ for (blockT *front = listHead, blockT *back = listHead; /.../ I would like to avoid pointer to a pointer. Do I just need to initialize these before the loop? As always, thanks!

  • How to get a category listing from Magento?

    - by alex
    I want to create a page in Magento that shows a visual representation of the categories.. example CATEGORY product 1 product 2 ANOTHER CATEGORY product 3 My problem is, their database is organised very differently to what I've seen in the past. They have tables dedicated to data types like varchar, int, etc. I assume this is for performance or similiar. I haven't found a way to use MySQL to query the database and get a list of categories. I'd then like to match these categories to products, to get a listing of products for each category. Unfortunately Magento seems to make this very difficult. Also I have not found a method that will work from within a page block.. I have created showcase.phtml and put it in the XML layout and it displays and runs it's PHP code. I was hoping for something easy like looping through $this-getAllCategories(); and then a nested loop inside with something like $category-getChildProducts(); Can anyone help me? Thank you!

  • How important is the website logo on a page?

    - by meo
    I have stopped to insert "img" tags for the logo of the page. Because its not an image that is part of the content, its a design element but its still a information I want to have control over. So I just write the title in a "a" element as display: block, overflow: hidden and I push the text out with some padding. I think thats a good solution for SEO because you are keeping control of how important the logo should be on a page. But now my dilemma is starting. How important is the logo of a page? "A list apart" puts the logo in a h1 element. But is the logo really that important? On article pages you have two H1 elements (the logo and the title of the article) Most of the sites just use a img balbal /a, but I don't like this solution. Because I just want to use img for images that are part of the content... Its kinda philosophical question, I hope you can give me some input or some articles to read about that...

    I've got a small script that detects if the user is using Google Chrome var is_chrome = navigator.userAgent.toLowerCase().indexOf('chrome') > -1; if(is_chrome){ $('.ifChrome').attr('style', 'display:block;'); $('.ifChrome').html($('noscript > div').html()); }; If they are using chrome, we want to display a div tag and show the HTML from a different div tag inside. <noscript> <div class="note"> Your browser does not properly support the WMD Markdown Editor.<br /> Please use <a href="/about/markdown" target="_blank">Markdown<.a> to style your input. </div> </noscript> <div class="hidden ifChrome note"></div> What I'm trying to do is show the "not supported" text from inside my <noscript> tag to users who are using google Chrome (because WMD Markdown doesn't work properly with Chrome). My existing Javascript is not working. Any help would be greatly appreciated.

  • Using an iterator without its container

    - by User1
    I am mixing some C and C++ libraries and have only a single pointer available to do some work in a callback function. All I need to do is iterate through a vector. Here's a simplified, untested example: bool call_back(void* data){ done=... if (!done) cout << *data++ << endl; return done; } Note that this function is in an extern "C" block in C++. call_back will be called until true is returned. I want it to cout the next element each time it's called. data is a pointer to something that I can pass from elsewhere in the code (an iterator in the above example, but can be anything). Something from data will likely be used to calculate done. I see two obvious options to give to data: Have data point to my vector. Have data point to an iterator of my vector. I can't use an iterator without having the .end() method available, right? I can't use a vector alone (unless maybe I start removing its data). I could make a struct with both vector and iterator, but is there a better way? What would you do?

  • include ::before pseudo class in javascript

    - by user1955837
    Why is this thing not working? If I remove ::before from javascript and css it works. But due to the design needs there has to be a ::before. How do I point to the class + ::before? $(function () { var sections = $("section"); var navigation_links = $("nav a"); sections.waypoint({ handler: function (event, direction) { var active_section; active_section = $(this); if (direction === "up") active_section = active_section.prev(); var active_link = $('nav a[href="#' + active_section.attr("id") + '"]'); navigation_links.removeClass("selected::before"); active_link.addClass("selected::before"); }, offset: '25%' }) }); css: .selected::before { display: block; content: ""; margin-top: 6px; width: 8px; height: 8px; background: url(../img/sprite.png) -126px -196px; background-size: 400px 480px; float: left; margin-left: 20px; margin-right: 20px; }

  • Holding variables in memory, C++

    - by b-gen-jack-o-neill
    Today something strange came to my mind. When I want to hold some string in C (C++) the old way, without using string header, I just create array and store that string into it. But, I read that any variable definition in C in local scope of function ends up in pushing these values onto the stack. So, the string is actually 2* bigger than needed. Because first, the push instructions are located in memory, but then when they are executed (pushed onto the stack) another "copy" of the string is created. First the push instructions, than the stack space is used for one string. So, why is it this way? Why doesn't compiler just add the string (or other variables) to the program instead of creating them once again when executed? Yes, I know you cannot just have some data inside program block, but it could just be attached to the end of the program, with some jump instruction before. And than, we would just point to these data? Because they are stored in RAM when the program is executed. Thanks.

  • Serialization for memcached

    - by Ram
    I have this huge domain object(say parent) which contains other domain objects. It takes a lot of time to "create" this parent object by querying a DB (OK we are optimizing the DB). So we decided to cache it using memcached (with northscale to be specific) So I have gone through my code and marked all the classes (I think) as [Serializable], but when I add it to the cache, I see a Serialization Exception getting thrown in my VS.net output window. var cache = new NorthScaleClient("MyBucket"); cache.Store(StoreMode.Set, key, value); This is the exception: A first chance exception of type 'System.Runtime.Serialization.SerializationException' occurred in mscorlib.dll SO my guess is, I have not marked all classes as [Serializable]. I am not using any third party libraries and can mark any class as [Serializable], but how do I find out which class is failing when the cache is trying to serialize the object ? Edit1: casperOne comments make me think. I was able to cache these domain object with Microsoft Cache Application Block without marking them [Serializable], but not with NorthScale memcached. It makes me think that there might be something to do with their implementation, but just out of curiosity, am still interested in finding where it fails when trying to add the object to memcached
