Is it possible to just deny download from TCP/IP?

- by Kerberos

I want to deny my Internet connection's download properties for all ports. I mean I want to only allow upload. Is it possible?

Limiting network throughput of an already launched process ? (Linux/FreeBSD)

Hello everybody, is there any utility to limit the network throughput of a process after it has been launched ? Simple example: you note that a user takes all your upload bandwidth using scp and you'd like to limit the rate or decrease the priority of the transfer. I guess i could use a combination of iptables/tc or pf to achieve that, but i was wondering if there is a "one-shot" tool available (like tickle with a --pid option ^^) ? Regards, Jean-Baptiste

RSS to e-mail notifications?

- by OverTheRainbow

There's a web site that's supposed to upload a video I'd like to watch but it could be in several weeks. The only way to be notified of any change is through RSS, but I don't use RSS at all, so installing an RSS client just for this seems overkill. Unless there's a better solution I should know about, do you know of a good, free solution on the web that will watch the RSS channel and send me an e-mail when a new item was added? Thank you.

Can I combine two LANs into one to get double speed?

- by Salaam

Hey guys, I have 2 LANs in my own PC & 2 Routers (TP-Link WR941N each) with 2 internet accounts (512Kbps each) connected to the same ISP signal & company using NanoStation 5 from ubnt. As you know the connections work separately by default! (I use Windows 7 64bit) Can I merge them to get double speed (download/upload simultaneously) using regedit or special software or any other method? I'd be much appreciated if u could help me doing that Best Regards, Salaam

Issue with Multiple ModalPopups, ValidationSummary and UpdatePanels

- by Aaron Hoffman

I am having an issue when a page contains multiple ModalPopups each containing a ValidationSummary Control. Here is the functionality I need: A user clicks a button and a Modal Popup appears with dynamic content based on the button that was clicked. (This functionality is working. Buttons are wrapped in UpdatePanels and the partial page postback calls .Show() on the ModalPopup) "Save" button in ModalPopup causes client side validation, then causes a full page postback so the entire ModalPopup disappears. (ModalPopup could disappear another way - the ModalPopup just needs to disappear after a successful save operation) If errors occur in the codebehind during Save operation, messages are added to the ValidationSummary (contained within the ModalPopup) and the ModalPopup is displayed again. When the ValidationSummary's are added to the PopupPanel's, the ModalPopups no longer display correctly after a full page postback caused by the "Save" button within the second PopupPanel. (the first panel continues to function correctly) Both PopupPanels are displayed, and neither is "Popped-Up", they are displayed in-line. Any ideas on how to solve this?

The remote server returned an error: (400) Bad Request - uploading less 2MB file size?

- by fiberOptics

The file succeed to upload when it is 2KB or lower in size. The main reason why I use streaming is to be able to upload file up to at least 1 GB. But when I try to upload file with less 1MB size, I get bad request. It is my first time to deal with downloading and uploading process, so I can't easily find the cause of error. Testing part: private void button24_Click(object sender, EventArgs e) { try { OpenFileDialog openfile = new OpenFileDialog(); if (openfile.ShowDialog() == System.Windows.Forms.DialogResult.OK) { string port = "3445"; byte[] fileStream; using (FileStream fs = new FileStream(openfile.FileName, FileMode.Open, FileAccess.Read, FileShare.Read)) { fileStream = new byte[fs.Length]; fs.Read(fileStream, 0, (int)fs.Length); fs.Close(); fs.Dispose(); } string baseAddress = "http://localhost:" + port + "/File/AddStream?fileID=9"; HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(baseAddress); request.Method = "POST"; request.ContentType = "text/plain"; //request.ContentType = "application/octet-stream"; Stream serverStream = request.GetRequestStream(); serverStream.Write(fileStream, 0, fileStream.Length); serverStream.Close(); using (HttpWebResponse response = request.GetResponse() as HttpWebResponse) { int statusCode = (int)response.StatusCode; StreamReader reader = new StreamReader(response.GetResponseStream()); } } } catch (Exception ex) { MessageBox.Show(ex.Message); } } Service: [WebInvoke(UriTemplate = "AddStream?fileID={fileID}", Method = "POST", BodyStyle = WebMessageBodyStyle.Bare)] public bool AddStream(long fileID, System.IO.Stream fileStream) { ClasslLogic.FileComponent svc = new ClasslLogic.FileComponent(); return svc.AddStream(fileID, fileStream); } Server code for streaming: namespace ClasslLogic { public class StreamObject : IStreamObject { public bool UploadFile(string filename, Stream fileStream) { try { FileStream fileToupload = new FileStream(filename, FileMode.Create); byte[] bytearray = new byte[10000]; int bytesRead, totalBytesRead = 0; do { bytesRead = fileStream.Read(bytearray, 0, bytearray.Length); totalBytesRead += bytesRead; } while (bytesRead > 0); fileToupload.Write(bytearray, 0, bytearray.Length); fileToupload.Close(); fileToupload.Dispose(); } catch (Exception ex) { throw new Exception(ex.Message); } return true; } } } Web config: <system.serviceModel> <bindings> <basicHttpBinding> <binding> <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="2097152" maxBytesPerRead="4096" maxNameTableCharCount="2097152" /> <security mode="None" /> </binding> <binding name="ClassLogicBasicTransfer" closeTimeout="00:05:00" openTimeout="00:05:00" receiveTimeout="00:15:00" sendTimeout="00:01:00" allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard" maxBufferPoolSize="67108864" maxReceivedMessageSize="67108864" messageEncoding="Mtom" textEncoding="utf-8" useDefaultWebProxy="true"> <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="67108864" maxBytesPerRead="4096" maxNameTableCharCount="67108864" /> <security mode="None"> <transport clientCredentialType="None" proxyCredentialType="None" realm="" /> <message clientCredentialType="UserName" algorithmSuite="Default" /> </security> </binding> <binding name="BaseLogicWSHTTP"> <security mode="None" /> </binding> <binding name="BaseLogicWSHTTPSec" /> </basicHttpBinding> </bindings> <behaviors> <serviceBehaviors> <behavior>  <serviceMetadata httpGetEnabled="true" />  <serviceDebug includeExceptionDetailInFaults="true" /> </behavior> </serviceBehaviors> </behaviors> <serviceHostingEnvironment multipleSiteBindingsEnabled="true" aspNetCompatibilityEnabled="true" /> </system.serviceModel> I'm not sure if this affects the streaming function, because I'm using WCF4.0 rest template which config is dependent in Global.asax. One more thing is this, whether I run the service and passing a stream or not, the created file always contain this thing. How could I remove the "NUL" data? Thanks in advance. Edit public bool UploadFile(string filename, Stream fileStream) { try { FileStream fileToupload = new FileStream(filename, FileMode.Create); byte[] bytearray = new byte[10000]; int bytesRead, totalBytesRead = 0; do { bytesRead = fileStream.Read(bytearray, totalBytesRead, bytearray.Length - totalBytesRead); totalBytesRead += bytesRead; } while (bytesRead > 0); fileToupload.Write(bytearray, 0, totalBytesRead); fileToupload.Close(); fileToupload.Dispose(); } catch (Exception ex) { throw new Exception(ex.Message); } return true; }

MediaElement.js setSrc() Loading The File But Not Changing pluginType

- by doubleJ

I'm working on a page that uses mediaelement.js to play mp3/mp4/wmv (yes, we have a lot of wmv). I have a list of links and those links should change the player. My effort is to make the changes to the player through javascript so that the page doesn't refresh. This code is working, but it refreshes every time. See a live demo of the non-ajax version. <?php $file = null; $file = $_GET["file"]; $format = null; if (preg_match("/mp4/i", $file)) $format = "mp4"; if (preg_match("/webm/i", $file)) $format = "webm"; if (preg_match("/wmv/i", $file)) $format = "wmv"; if (preg_match("/mp3/i", $file)) $format = "mp3"; if (preg_match("/ogg/i", $file)) $format = "ogg"; $mime = null; if ($format == "mp4") $mime = "video/mp4"; if ($format == "webm") $mime = "video/webm"; if ($format == "wmv") $mime = "video/wmv"; if ($format == "mp3") $mime = "audio/mp3"; if ($format == "ogg") $mime = "audio/ogg"; $element = "video"; if ($format == "mp3" || $format == "ogg") $element = "audio"; // you have to escape (\) the escape (\) character (hehehe...) $poster = "media\\120701Video.jpg"; $height = "360"; if ($format == "mp3") $height = "30"; ?> <!doctype html> <html> <head> <meta charset="utf-8"> <title>Embed</title> <link rel="stylesheet" href="include/johndyer-mediaelement-b090320/build/mediaelementplayer.min.css"> <style> audio {width:640px; height:30px;} video {width:640px; height:360px;} </style> <script src="include/johndyer-mediaelement-b090320/build/jquery.js"></script> <script src="include/johndyer-mediaelement-b090320/build/mediaelement-and-player.js"></script> </head> <body> <ul> <li><a href="embed.php">Reset</a></li> <li><a href="?file=media/120701Video-AnyVideoConverter.mp4">Alternative (mp4)</a></li> <li><a href="?file=media/120701Video-Ffmpeg-Defaults.webm">Alternative (webm)</a></li> <li><a href="?file=media/AreYouHurting-Death.wmv">Alternative (wmv)</a><li> <li><a href="?file=media/AreYouHurting-Death.mp3">Alternative (mp3)</a></li> </ul> <?php if ($file) { ?> <video src="<?php echo $file; ?>" controls poster="<?php echo $poster; ?>" width="640" height="360"></video> <div id="type"></div> <script> var video = document.getElementsByTagName("video")[0]; var player = new MediaElementPlayer(video, { success: function(player) { $('#type').html(player.pluginType); } }); <?php } ?> </script> </body> </html> This code requires <video> to be loaded, initially and with a file, so that the player mode (pluginType) is set.

I've read a couple pages that referenced refreshing the DOM after the javascript runs, but I haven't been able to successfully do it (I know enough about javascript to hack things around and get stuff working, but not enough to create whole new things). It is worth noting that Silverlight doesn't work with Internet Explorer 8 or Safari (not sure if it's my code, mejs, or the browsers). Also, neither Silverlight nor Flash play mp3 or webm (again, not sure where the problem lies). Is there a way to dynamically load different types of files into mediaelement?

bandwidth throttling C linux

- by bob moch

hi im currently creating a function to create a sleep time i can pause between packets for my port scanner im creating for personal/educational use for my home network. what im currently doing is opening /proc/net/dev and reading the 9th set of digits for the eth0 interface to find out the current packets being set and then reading it again and doing some math to figure out a delay to sleep between sending a packet to a port to identify it and fingerprint it. my problem is that no matter what throttle % i use it always seems to send the same rate of packets. i think its mainly my way of mathematically creating my sleep delay. edit:: dont mind the function declaration and the struct stuff all im doing is spawning this function in a thread and passing a pointer to a struct to the function, recreating the struct locally and then freeing the passed structs memory. void *bandwidthmonitor_cmd(void *param) { char cmdline[1024], *bytedata[19]; int i = 0, ii = 0; long long prevbytes = 0, currentbytes = 0, elapsedbytes = 0, byteusage = 0, maxthrottle = 0; command_struct bandwidth = *((command_struct *)param); free(param); //printf("speed: %d\n throttle: %d\n\n", UPLOAD_SPEED, bandwidth.throttle); maxthrottle = UPLOAD_SPEED * bandwidth.throttle / 100; //printf("max throttle:%lld\n", maxthrottle); FILE *f = fopen("/proc/net/dev", "r"); if(f != NULL) { while(1) { while(fgets(cmdline, sizeof(cmdline), f) != NULL) { cmdline[strlen(cmdline)] = '\0'; if(strncmp(cmdline, " eth0", 6) == 0) { bytedata[0] = strtok(cmdline, " "); while(bytedata[i] != NULL) { i++; bytedata[i] = strtok(NULL, " "); } bytedata[i + 1] = '\0'; currentbytes = atoi(bytedata[9]); } } i = 0; rewind(f); elapsedbytes = currentbytes - prevbytes; prevbytes = currentbytes; byteusage = 8 * (elapsedbytes / 1024); //printf("usage:%lld\n",byteusage); if(ii & 0x40) { SLEEP += (maxthrottle - byteusage) * -1.1;//-2.5; if(SLEEP < 0){ SLEEP = 0; } //printf("sleep:%d\n", SLEEP); } usleep(25000); ii++; } } return NULL; } SLEEP and UPLOAD_SPEED are global variables and UPLOAD_SPEED is in kb/s and generated via a speedtest function that gets the upload speed of my computer. this function is running inside a POSIX thread updating SLEEP which my threads doing the socket work grab to sleep by after every packet. as testing instead of only doing the ports i want to check i make it do all the ports over and over again so i can run dstat on a machine to check bandwidth and no matter what bandwidth.throttle is set to it always seems to generate the same amount of bandwidth to the dstat machine. the way i calculate how much i "should" throttle by is by finding the maximum throttle speed which is defined as maxthrottle = upload_speed * throttle / 100; for example if my upload speed was 1000kb/s and my throttle was 90 (90%) my max throttle would be 900kb/s from there it would find the current bytes sent from /proc/net/dev and then find my sleep time via incrementing or decrementing it via sleep += (maxthrottle - bytesysed) * -1.1; this should in theory increase or decrease the sleep time based on how many bytes used there are. the if(ii & 0x40) statement is just for some moderation control. it makes it so it only sets sleep to a new time every 30-40 iterations. final notes: the main problem is that the sleep timer does not seem to modify the speed of packets being set. or maybe its just my implementation because on a freshly restarted machine where /proc/net/dev has low numbers of bytes sent it seems to raise the sleep timer accordingly on my 60kb/s upload machine (ex if i set the throttle to 2 it will incline the sleep timer until network bandwidth out reaches the max bandwidth threshold, but when i try running it on a server which as been online forever it doesnt seem to work as nicely if at all. if anyone can suggest a new method of monitoring the network to adjust a sleep delay then let me know or if anyone sees a flaw in my code. thank you.

What’s New in ASP.NET 4.0 Part Two: WebForms and Visual Studio Enhancements

- by Rick Strahl

In the last installment I talked about the core changes in the ASP.NET runtime that I’ve been taking advantage of. In this column, I’ll cover the changes to the Web Forms engine and some of the cool improvements in Visual Studio that make Web and general development easier. WebForms The WebForms engine is the area that has received most significant changes in ASP.NET 4.0. Probably the most widely anticipated features are related to managing page client ids and of ViewState on WebForm pages. Take Control of Your ClientIDs Unique ClientID generation in ASP.NET has been one of the most complained about “features” in ASP.NET. Although there’s a very good technical reason for these unique generated ids - they guarantee unique ids for each and every server control on a page - these unique and generated ids often get in the way of client-side JavaScript development and CSS styling as it’s often inconvenient and fragile to work with the long, generated ClientIDs. In ASP.NET 4.0 you can now specify an explicit client id mode on each control or each naming container parent control to control how client ids are generated. By default, ASP.NET generates mangled client ids for any control contained in a naming container (like a Master Page, or a User Control for example). The key to ClientID management in ASP.NET 4.0 are the new ClientIDMode and ClientIDRowSuffix properties. ClientIDMode supports four different ClientID generation settings shown below. For the following examples, imagine that you have a Textbox control named txtName inside of a master page control container on a WebForms page. <%@Page Language="C#" MasterPageFile="~/Site.Master" CodeBehind="WebForm2.aspx.cs" Inherits="WebApplication1.WebForm2" %> <asp:Content ID="content" ContentPlaceHolderID="content" runat="server" ClientIDMode="Static" > <asp:TextBox runat="server" ID="txtName" /> </asp:Content> The four available ClientIDMode values are: AutoID This is the existing behavior in ASP.NET 1.x-3.x where full naming container munging takes place. <input name="ctl00$content$txtName" type="text" id="ctl00_content_txtName" /> This should be familiar to any ASP.NET developer and results in fairly unpredictable client ids that can easily change if the containership hierarchy changes. For example, removing the master page changes the name in this case, so if you were to move a block of script code that works against the control to a non-Master page, the script code immediately breaks. Static This option is the most deterministic setting that forces the control’s ClientID to use its ID value directly. No naming container naming at all is applied and you end up with clean client ids: <input name="ctl00$content$txtName" type="text" id="txtName" /> Note that the name property which is used for postback variables to the server still is munged, but the ClientID property is displayed simply as the ID value that you have assigned to the control. This option is what most of us want to use, but you have to be clear on that because it can potentially cause conflicts with other controls on the page. If there are several instances of the same naming container (several instances of the same user control for example) there can easily be a client id naming conflict. Note that if you assign Static to a data-bound control, like a list child control in templates, you do not get unique ids either, so for list controls where you rely on unique id for child controls, you’ll probably want to use Predictable rather than Static. I’ll write more on this a little later when I discuss ClientIDRowSuffix. Predictable The previous two values are pretty self-explanatory. Predictable however, requires some explanation. To me at least it’s not in the least bit predictable. MSDN defines this value as follows: This algorithm is used for controls that are in data-bound controls. The ClientID value is generated by concatenating the ClientID value of the parent naming container with the ID value of the control. If the control is a data-bound control that generates multiple rows, the value of the data field specified in the ClientIDRowSuffix property is added at the end. For the GridView control, multiple data fields can be specified. If the ClientIDRowSuffix property is blank, a sequential number is added at the end instead of a data-field value. Each segment is separated by an underscore character (_). The key that makes this value a bit confusing is that it relies on the parent NamingContainer’s ClientID to build its own ClientID value. This effectively means that the value is not predictable at all but rather very tightly coupled to the parent naming container’s ClientIDMode setting. For my simple textbox example, if the ClientIDMode property of the parent naming container (Page in this case) is set to “Predictable” you’ll get this: <input name="ctl00$content$txtName" type="text" id="content_txtName" /> which gives an id that based on walking up to the currently active naming container (the MasterPage content container) and starting the id formatting from there downward. Think of this as a semi unique name that’s guaranteed unique only for the naming container. If, on the other hand, the Page is set to “AutoID” you get the following with Predictable on txtName: <input name="ctl00$content$txtName" type="text" id="ctl00_content_txtName" /> The latter is effectively the same as if you specified AutoID because it inherits the AutoID naming from the Page and Content Master Page control of the page. But again - predictable behavior always depends on the parent naming container and how it generates its id, so the id may not always be exactly the same as the AutoID generated value because somewhere in the NamingContainer chain the ClientIDMode setting may be set to a different value. For example, if you had another naming container in the middle that was set to Static you’d end up effectively with an id that starts with the NamingContainers id rather than the whole ctl000_content munging. The most common use for Predictable is likely to be for data-bound controls, which results in each data bound item getting a unique ClientID. Unfortunately, even here the behavior can be very unpredictable depending on which data-bound control you use - I found significant differences in how template controls in a GridView behave from those that are used in a ListView control. For example, GridView creates clean child ClientIDs, while ListView still has a naming container in the ClientID, presumably because of the template container on which you can’t set ClientIDMode. Predictable is useful, but only if all naming containers down the chain use this setting. Otherwise you’re right back to the munged ids that are pretty unpredictable. Another property, ClientIDRowSuffix, can be used in combination with ClientIDMode of Predictable to force a suffix onto list client controls. For example: <asp:GridView runat="server" ID="gvItems" AutoGenerateColumns="false" ClientIDMode="Static" ClientIDRowSuffix="Id"> <Columns> <asp:TemplateField> <ItemTemplate> <asp:Label runat="server" id="txtName" Text='<%# Eval("Name") %>' ClientIDMode="Predictable"/> </ItemTemplate> </asp:TemplateField> <asp:TemplateField> <ItemTemplate> <asp:Label runat="server" id="txtId" Text='<%# Eval("Id") %>' ClientIDMode="Predictable" /> </ItemTemplate> </asp:TemplateField> </Columns> </asp:GridView> generates client Ids inside of a column in the master page described earlier: <td> <span id="txtName_0">Rick</span> </td> where the value after the underscore is the ClientIDRowSuffix field - in this case “Id” of the item data bound to the control. Note that all of the child controls require ClientIDMode=”Predictable” in order for the ClientIDRowSuffix to be applied, and the parent GridView controls need to be set to Static either explicitly or via Naming Container inheritance to give these simple names. It’s a bummer that ClientIDRowSuffix doesn’t work with Static to produce this automatically. Another real problem is that other controls process the ClientIDMode differently. For example, a ListView control processes the Predictable ClientIDMode differently and produces the following with the Static ListView and Predictable child controls: <span id="ctrl0_txtName_0">Rick</span> I couldn’t even figure out a way using ClientIDMode to get a simple ID that also uses a suffix short of falling back to manually generated ids using <%= %> expressions instead. Given the inconsistencies inside of list controls using <%= %>, ids for the ListView might not be a bad idea anyway. Inherit The final setting is Inherit, which is the default for all controls except Page. This means that controls by default inherit the parent naming container’s ClientIDMode setting. For more detailed information on ClientID behavior and different scenarios you can check out a blog post of mine on this subject: http://www.west-wind.com/weblog/posts/54760.aspx. ClientID Enhancements Summary The ClientIDMode property is a welcome addition to ASP.NET 4.0. To me this is probably the most useful WebForms feature as it allows me to generate clean IDs simply by setting ClientIDMode="Static" on either the page or inside of Web.config (in the Pages section) which applies the setting down to the entire page which is my 95% scenario. For the few cases when it matters - for list controls and inside of multi-use user controls or custom server controls) - I can use Predictable or even AutoID to force controls to unique names. For application-level page development, this is easy to accomplish and provides maximum usability for working with client script code against page controls. ViewStateMode Another area of large criticism for WebForms is ViewState. ViewState is used internally by ASP.NET to persist page-level changes to non-postback properties on controls as pages post back to the server. It’s a useful mechanism that works great for the overall mechanics of WebForms, but it can also cause all sorts of overhead for page operation as ViewState can very quickly get out of control and consume huge amounts of bandwidth in your page content. ViewState can also wreak havoc with client-side scripting applications that modify control properties that are tracked by ViewState, which can produce very unpredictable results on a Postback after client-side updates. Over the years in my own development, I’ve often turned off ViewState on pages to reduce overhead. Yes, you lose some functionality, but you can easily implement most of the common functionality in non-ViewState workarounds. Relying less on heavy ViewState controls and sticking with simpler controls or raw HTML constructs avoids getting around ViewState problems. In ASP.NET 3.x and prior, it wasn’t easy to control ViewState - you could turn it on or off and if you turned it off at the page or web.config level, you couldn’t turn it back on for specific controls. In short, it was an all or nothing approach. With ASP.NET 4.0, the new ViewStateMode property gives you more control. It allows you to disable ViewState globally either on the page or web.config level and then turn it back on for specific controls that might need it. ViewStateMode only works when EnableViewState="true" on the page or web.config level (which is the default). You can then use ViewStateMode of Disabled, Enabled or Inherit to control the ViewState settings on the page. If you’re shooting for minimal ViewState usage, the ideal situation is to set ViewStateMode to disabled on the Page or web.config level and only turn it back on particular controls: <%@Page Language="C#" CodeBehind="WebForm2.aspx.cs" Inherits="Westwind.WebStore.WebForm2" ClientIDMode="Static" ViewStateMode="Disabled" EnableViewState="true" %>  <asp:TextBox runat="server" ID="txtName" ViewStateMode="Enabled" />  <asp:TextBox runat="server" ID="txtAddress" /> Note that the EnableViewState="true" at the Page level isn’t required since it’s the default, but it’s important that the value is true. ViewStateMode has no effect if EnableViewState="false" at the page level. The main benefit of ViewStateMode is that it allows you to more easily turn off ViewState for most of the page and enable only a few key controls that might need it. For me personally, this is a perfect combination as most of my WebForm apps can get away without any ViewState at all. But some controls - especially third party controls - often don’t work well without ViewState enabled, and now it’s much easier to selectively enable controls rather than the old way, which required you to pretty much turn off ViewState for all controls that you didn’t want ViewState on. Inline HTML Encoding HTML encoding is an important feature to prevent cross-site scripting attacks in data entered by users on your site. In order to make it easier to create HTML encoded content, ASP.NET 4.0 introduces a new Expression syntax using <%: %> to encode string values. The encoding expression syntax looks like this: <%: "<script type='text/javascript'>" + "alert('Really?');</script>" %> which produces properly encoded HTML: <script type='text/javascript' >alert('Really?');</script> Effectively this is a shortcut to: <%= HttpUtility.HtmlEncode( "<script type='text/javascript'>" + "alert('Really?');</script>") %> Of course the <%: %> syntax can also evaluate expressions just like <%= %> so the more common scenario applies this expression syntax against data your application is displaying. Here’s an example displaying some data model values: <%: Model.Address.Street %> This snippet shows displaying data from your application’s data store or more importantly, from data entered by users. Anything that makes it easier and less verbose to HtmlEncode text is a welcome addition to avoid potential cross-site scripting attacks. Although I listed Inline HTML Encoding here under WebForms, anything that uses the WebForms rendering engine including ASP.NET MVC, benefits from this feature. ScriptManager Enhancements The ASP.NET ScriptManager control in the past has introduced some nice ways to take programmatic and markup control over script loading, but there were a number of shortcomings in this control. The ASP.NET 4.0 ScriptManager has a number of improvements that make it easier to control script loading and addresses a few of the shortcomings that have often kept me from using the control in favor of manual script loading. The first is the AjaxFrameworkMode property which finally lets you suppress loading the ASP.NET AJAX runtime. Disabled doesn’t load any ASP.NET AJAX libraries, but there’s also an Explicit mode that lets you pick and choose the library pieces individually and reduce the footprint of ASP.NET AJAX script included if you are using the library. There’s also a new EnableCdn property that forces any script that has a new WebResource attribute CdnPath property set to a CDN supplied URL. If the script has this Attribute property set to a non-null/empty value and EnableCdn is enabled on the ScriptManager, that script will be served from the specified CdnPath. [assembly: WebResource( "Westwind.Web.Resources.ww.jquery.js", "application/x-javascript", CdnPath = "http://mysite.com/scripts/ww.jquery.min.js")] Cool, but a little too static for my taste since this value can’t be changed at runtime to point at a debug script as needed, for example. Assembly names for loading scripts from resources can now be simple names rather than fully qualified assembly names, which make it less verbose to reference scripts from assemblies loaded from your bin folder or the assembly reference area in web.config: <asp:ScriptManager runat="server" id="Id" EnableCdn="true" AjaxFrameworkMode="disabled"> <Scripts> <asp:ScriptReference Name="Westwind.Web.Resources.ww.jquery.js" Assembly="Westwind.Web" /> </Scripts> </asp:ScriptManager> The ScriptManager in 4.0 also supports script combining via the CompositeScript tag, which allows you to very easily combine scripts into a single script resource served via ASP.NET. Even nicer: You can specify the URL that the combined script is served with. Check out the following script manager markup that combines several static file scripts and a script resource into a single ASP.NET served resource from a static URL (allscripts.js): <asp:ScriptManager runat="server" id="Id" EnableCdn="true" AjaxFrameworkMode="disabled"> <CompositeScript Path="~/scripts/allscripts.js"> <Scripts> <asp:ScriptReference Path="~/scripts/jquery.js" /> <asp:ScriptReference Path="~/scripts/ww.jquery.js" /> <asp:ScriptReference Name="Westwind.Web.Resources.editors.js" Assembly="Westwind.Web" /> </Scripts> </CompositeScript> </asp:ScriptManager> When you render this into HTML, you’ll see a single script reference in the page: <script src="scripts/allscripts.debug.js" type="text/javascript"></script> All you need to do to make this work is ensure that allscripts.js and allscripts.debug.js exist in the scripts folder of your application - they can be empty but the file has to be there. This is pretty cool, but you want to be real careful that you use unique URLs for each combination of scripts you combine or else browser and server caching will easily screw you up royally. The script manager also allows you to override native ASP.NET AJAX scripts now as any script references defined in the Scripts section of the ScriptManager trump internal references. So if you want custom behavior or you want to fix a possible bug in the core libraries that normally are loaded from resources, you can now do this simply by referencing the script resource name in the Name property and pointing at System.Web for the assembly. Not a common scenario, but when you need it, it can come in real handy. Still, there are a number of shortcomings in this control. For one, the ScriptManager and ClientScript APIs still have no common entry point so control developers are still faced with having to check and support both APIs to load scripts so that controls can work on pages that do or don’t have a ScriptManager on the page. The CdnUrl is static and compiled in, which is very restrictive. And finally, there’s still no control over where scripts get loaded on the page - ScriptManager still injects scripts into the middle of the HTML markup rather than in the header or optionally the footer. This, in turn, means there is little control over script loading order, which can be problematic for control developers. MetaDescription, MetaKeywords Page Properties There are also a number of additional Page properties that correspond to some of the other features discussed in this column: ClientIDMode, ClientTarget and ViewStateMode. Another minor but useful feature is that you can now directly access the MetaDescription and MetaKeywords properties on the Page object to set the corresponding meta tags programmatically. Updating these values programmatically previously required either <%= %> expressions in the page markup or dynamic insertion of literal controls into the page. You can now just set these properties programmatically on the Page object in any Control derived class on the page or the Page itself: Page.MetaKeywords = "ASP.NET,4.0,New Features"; Page.MetaDescription = "This article discusses the new features in ASP.NET 4.0"; Note, that there’s no corresponding ASP.NET tag for the HTML Meta element, so the only way to specify these values in markup and access them is via the @Page tag: <%@Page Language="C#" CodeBehind="WebForm2.aspx.cs" Inherits="Westwind.WebStore.WebForm2" ClientIDMode="Static" MetaDescription="Article that discusses what's new in ASP.NET 4.0" MetaKeywords="ASP.NET,4.0,New Features" %> Nothing earth shattering but quite convenient. Visual Studio 2010 Enhancements for Web Development For Web development there are also a host of editor enhancements in Visual Studio 2010. Some of these are not Web specific but they are useful for Web developers in general. Text Editors Throughout Visual Studio 2010, the text editors have all been updated to a new core engine based on WPF which provides some interesting new features for various code editors including the nice ability to zoom in and out with Ctrl-MouseWheel to quickly change the size of text. There are many more API options to control the editor and although Visual Studio 2010 doesn’t yet use many of these features, we can look forward to enhancements in add-ins and future editor updates from the various language teams that take advantage of the visual richness that WPF provides to editing. On the negative side, I’ve noticed that occasionally the code editor and especially the HTML and JavaScript editors will lose the ability to use various navigation keys like arrows, back and delete keys, which requires closing and reopening the documents at times. This issue seems to be well documented so I suspect this will be addressed soon with a hotfix or within the first service pack. Overall though, the code editors work very well, especially given that they were re-written completely using WPF, which was one of my big worries when I first heard about the complete redesign of the editors. Multi-Targeting Visual Studio now targets all versions of the .NET framework from 2.0 forward. You can use Visual Studio 2010 to work on your ASP.NET 2, 3.0 and 3.5 applications which is a nice way to get your feet wet with the new development environment without having to make changes to existing applications. It’s nice to have one tool to work in for all the different versions. Multi-Monitor Support One cool feature of Visual Studio 2010 is the ability to drag windows out of the Visual Studio environment and out onto the desktop including onto another monitor easily. Since Web development often involves working with a host of designers at the same time - visual designer, HTML markup window, code behind and JavaScript editor - it’s really nice to be able to have a little more screen real estate to work on each of these editors. Microsoft made a welcome change in the environment. IntelliSense Snippets for HTML and JavaScript Editors The HTML and JavaScript editors now finally support IntelliSense scripts to create macro-based template expansions that have been in the core C# and Visual Basic code editors since Visual Studio 2005. Snippets allow you to create short XML-based template definitions that can act as static macros or real templates that can have replaceable values that can be embedded into the expanded text. The XML syntax for these snippets is straight forward and it’s pretty easy to create custom snippets manually. You can easily create snippets using XML and store them in your custom snippets folder (C:\Users\rstrahl\Documents\Visual Studio 2010\Code Snippets\Visual Web Developer\My HTML Snippets and My JScript Snippets), but it helps to use one of the third-party tools that exist to simplify the process for you. I use SnippetEditor, by Bill McCarthy, which makes short work of creating snippets interactively (http://snippeteditor.codeplex.com/). Note: You may have to manually add the Visual Studio 2010 User specific Snippet folders to this tool to see existing ones you’ve created. Code snippets are some of the biggest time savers and HTML editing more than anything deals with lots of repetitive tasks that lend themselves to text expansion. Visual Studio 2010 includes a slew of built-in snippets (that you can also customize!) and you can create your own very easily. If you haven’t done so already, I encourage you to spend a little time examining your coding patterns and find the repetitive code that you write and convert it into snippets. I’ve been using CodeRush for this for years, but now you can do much of the basic expansion natively for HTML and JavaScript snippets. jQuery Integration Is Now Native jQuery is a popular JavaScript library and recently Microsoft has recently stated that it will become the primary client-side scripting technology to drive higher level script functionality in various ASP.NET Web projects that Microsoft provides. In Visual Studio 2010, the default full project template includes jQuery as part of a new project including the support files that provide IntelliSense (-vsdoc files). IntelliSense support for jQuery is now also baked into Visual Studio 2010, so unlike Visual Studio 2008 which required a separate download, no further installs are required for a rich IntelliSense experience with jQuery. Summary ASP.NET 4.0 brings many useful improvements to the platform, but thankfully most of the changes are incremental changes that don’t compromise backwards compatibility and they allow developers to ease into the new features one feature at a time. None of the changes in ASP.NET 4.0 or Visual Studio 2010 are monumental or game changers. The bigger features are language and .NET Framework changes that are also optional. This ASP.NET and tools release feels more like fine tuning and getting some long-standing kinks worked out of the platform. It shows that the ASP.NET team is dedicated to paying attention to community feedback and responding with changes to the platform and development environment based on this feedback. If you haven’t gotten your feet wet with ASP.NET 4.0 and Visual Studio 2010, there’s no reason not to give it a shot now - the ASP.NET 4.0 platform is solid and Visual Studio 2010 works very well for a brand new release. Check it out. © Rick Strahl, West Wind Technologies, 2005-2010Posted in ASP.NET

401 Using Multiple Authentication methods IE 10 only

- by jon3laze

I am not sure if this is more of a coding issue or server setup issue so I've posted it on stackoverflow and here... On our production site we've run into an issue that is specific to Internet Explorer 10. I am using jQuery doing an ajax POST to a web service on the same domain and in IE10 I am getting a 401 response, IE9 works perfectly fine. I should mention that we have mirrored code in another area of our site and it works perfectly fine in IE10. The only difference between the two areas is that one is under a subdomain and the other is at the root level. www.my1stdomain.com vs. portal.my2nddomain.com The directory structure on the server for these are: \my1stdomain\webservice\name\service.aspx \portal\webservice\name\service.aspx Inside of the \portal\ and \my1stdomain\ folders I have a page that does an ajax call, both pages are identical. $.ajax({ type: 'POST', url: '/webservice/name/service.aspx/function', cache: false, contentType: 'application/json; charset=utf-8', dataType: 'json', data: '{ "json": "data" }', success: function() { }, error: function() { } }); I've verified permissions are the same on both folders on the server side. I've applied a workaround fix of placing the <meta http-equiv="X-UA-Compatible" value="IE=9"> to force compatibility view (putting IE into compatibility mode fixes the issue). This seems to be working in IE10 on Windows 7, however IE 10 on Windows 8 still sees the same issue. These pages are classic asp with the headers that are being included, also there are no other meta tags being used. The doctype is being specified as <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//" "http://www.w3.org/TR/html4/loose.dtd"> on the portal page and <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> on the main domain. UPDATE1 I used Microsoft Network Monitor 3.4 on the server to capture the request. I used the following filter to capture the 401: Property.HttpStatusCode.StringToNumber == 401 This was the response - Http: Response, HTTP/1.1, Status: Unauthorized, URL: /webservice/name/service.aspx/function Using Multiple Authetication Methods, see frame details ProtocolVersion: HTTP/1.1 StatusCode: 401, Unauthorized Reason: Unauthorized - ContentType: application/json; charset=utf-8 - MediaType: application/json; charset=utf-8 MainType: application/json charset: utf-8 Server: Microsoft-IIS/7.0 jsonerror: true - WWWAuthenticate: Negotiate - Authenticate: Negotiate WhiteSpace: AuthenticateData: Negotiate - WWWAuthenticate: NTLM - Authenticate: NTLM WhiteSpace: AuthenticateData: NTLM XPoweredBy: ASP.NET Date: Mon, 04 Mar 2013 21:13:39 GMT ContentLength: 105 HeaderEnd: CRLF - payload: HttpContentType = application/json; charset=utf-8 HTTPPayloadLine: {"Message":"Authentication failed.","StackTrace":null,"ExceptionType":"System.InvalidOperationException"} The thing here that really stands out is Unauthorized, URL: /webservice/name/service.aspx/function Using Multiple Authentication Methods With this I'm still confused as to why this only happens in IE10 if it's a permission/authentication issue. What was added to 10, or where should I be looking for the root cause of this?

HTML: Place an image on top of another one

- by Dimitris Baltas

Inside a div, there is a picture that should have 10px margin in all directions from the DIV's border. On the left bottom corner of the picture there is an about-image. The picture is only displayed when its loaded in the DOM through jquery. The problem is that the existence of the about-image dislocates the picture downwards as many pixels as the height of the about-image. I am looking for the cleanest possible alternative to keep the picture inside the DIV and still display the about-image on top of it. Setting the picture as background will not work since i need the picture to load at once. Any improvement on the #about css would be greatly appreciated. Below is a full html page that reproduces the issue <html> <head> <title>Troubleshooting :: align the main picture inside the DIV</title> <style type="text/css"> html, body { background-color: #000000; } #about { z-index:2; position:relative; top:82%; left:3%; } #pic { width:100%; height:96%; } #main-content-image { height:100%; margin-right:10px; margin-left:10px; margin-top:10px; margin-bottom:10px; } #main-content { height:490px; border-width: 1px; border-style: solid; border-color: #777777; } #main-content-image.loading { background: url(http://farros.gr/images/ajax-loader2.gif) no-repeat center center; } a { text-decoration: none; text-decoration: none; color: #868686; outline:none; } .hide { display:none; } </style> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"></script> <script type="text/javascript"> <!-- $(document).ready(function(){ $(function () { var img = new Image(); $(img).load(function () { $(this).hide(); $(this).width('100%'); $(this).height('96%'); $('#main-content-image').removeClass('loading').append(this); $(this).fadeIn(); }).error(function () { // notify the user that the image could not be loaded }).attr('src', 'http://farros.gr/images/bg.jpg'); }); }); </script> </head> <body> <div id="main-content"> <div id="main-content-image" class="loading"> <a href="#"><img id="about" src='http://farros.gr/images/about.png' alt='Haris Farros'/></a> </div> </div> </body> </html>

Mouseover triggered on absolute positioned div

- by Tauren

Objective Have a small magnifying glass icon that appears in the top right corner of a table cell when the table cell is hovered over. Mousing over the magnifying glass icon and clicking it will open a dialog window to show detailed information about the item in that particular table cell. I want to reuse the same icon for hundreds of table cells without recreating it each time. Partial Solution Have a single <span> that is absolutely positioned and hidden. When a _previewable table cell is hovered, the <span> is moved to the correct location and shown. This <span> is also moved in the DOM to be a child of the _previewable table cell. This enables a click handler attached to the <span> to find the _previewable parent, and get information from it's jquery data() object that is used to populate the contents of the dialog. Here is a very simplified version of my HTML: <body> <span id="options"> <a class="ui-state-default ui-corner-all"> <span class="ui-icon ui-icon-search"></span> Preview </a> </span> <table> <tr> <td class="_previewable"> <img scr="user_1.png"/> <span>Bob Smith</span> </td> </tr> </table> </body> And this CSS: #options { position: absolute; display: none; } With this jQuery code: var $options = $('#options'); $options.click(function() { $item = $(this).parents("._previewable"); // Show popup based on data in $item.data("id"); Layout.renderPopup($item.data("id"),$item.data("popup")); }); $('._previewable').live('mouseover mouseout',function(event) { if (event.type == 'mouseover') { var $target = $(this); var $parent = $target.offsetParent()[0]; var left = $parent.scrollLeft + $target.position().left + $target.outerWidth() - $options.outerWidth() + 1; var top = $parent.scrollTop + $target.position().top + 2; $options.appendTo($target); $options.css({ "left": left + "px", "top": top + "px" }).show(); } else { // On mouseout, $options continues to be a child of $(this) $options.hide(); } }); Problem This solution works perfectly until the contents of my table are reloaded or changed via AJAX. Because the <span> was moved from the <body> to be a child of the cell, it gets thrown out and replaced during the AJAX call. So my first thought is to move the <span> back to the body on mouseout of the table cell, like this: else { // On mouseout, $options is moved back to be a child of body $options.appendTo("body"); $options.hide(); } However, with this, the <span> disappears as soon as it is mouseover. The mouseout event seems to be called on _previewable when the mouse moves into the <span>, even though the <span> is a child of _previewable and fully displayed within the boundaries of the _previewable table cell. At this point, I've only tested this in Chrome. Questions Why would mouseout be called on _previewable, when the mouse is still within the boundaries of _previewable? Is it because the <span> is absolutely positioned? How can I make this work, without recreating the <span> and it's click handler on each AJAX table referesh?

swap a div to an embed form when user tweets using the @anywhere function box

- by Jeff

I'm using the @anywhere twitter function on the front page of my site (vocabbomb.com) and right now it works great to allow users to tweet straight away. Problem is, when they click tweet, it just reloads the twitter box, empty. I want it to load something new, like a "thank you, now fill in this email form" and show a mailchimp form. Ok so this is the @anywhere code currently working fine: <div id="tbox"></div> <script type="text/javascript"> twttr.anywhere(function (T) { T("#tbox").tweetBox({ height: 100, width: 400, defaultContent: " #vocabbomb", label: "Use the word foo in a tweet:", }); }); </script> So this is fine, and when the user writes a tweet, it just re-displays the twitter box. I understand there is a function that lets you specify stuff after the tweet is made: (example from http://dev.twitter.com/pages/anywhere_tweetbox) <div id="example-ontweet"></div> <script type="text/javascript"> twttr.anywhere(function (T) { T("#example-ontweet").tweetBox({ onTweet : function(plaintext, html) { console.log(plaintext); alert(html); } }); }); </script> Is this the best way to attempt this? Or do I need a function or something that changes what's in the div to something else? I want the mailchimp email form to show up after the tweet. It includes a ton of script and tags and starts like this:    <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.2.6/jquery.min.js"></script> <script type="text/javascript" src="http://downloads.mailchimp.com/js/jquery.validate.js"></script> <script type="text/javascript" src="http://downloads.mailchimp.com/js/jquery.form.js"></script> <div id="mc_embed_signup"> <form action="http://faresharenyc.us1.list-manage.com/subscribe/post?u=106b58b4751a007d826715754&id=2fe6ba4e6a" method="post" id="mc-embedded-subscribe-form" name="mc-embedded-subscribe-form" class="validate" target="_blank" style="font: normal 100% Arial, sans-serif;font-size: 10px;"> ... So my attempt to just require it inside the function didn't work at all: <div id="tbox"></div> <script type="text/javascript"> twttr.anywhere(function (T) { T("#tbox").tweetBox({ height: 100, width: 400, defaultContent: " #vocabbomb", label: "Use the word foo in a tweet:", onTweet: function(plain, html){ <?php require_once('mailchimp.html'); ?> } }); }); </script> Nettuts had a brief discussion here: http://net.tutsplus.com/tutorials/javascript-ajax/using-twitters-anywhere-service-in-6-steps/ I am seeing now that the 'onTweet' function simply adds some text above the twitter box, but doesn't actually replace the entire twitter box. How do I do that? Is it possible? Thanks!

What are the principles of developing web-applications with action-based java frameworks?

- by Roman

Background I'm going to develop a new web-application with java. It's not very big or very complex and I have enough time until it'll "officially" start. I have some JSF/Facelets development background (about half a year). And I also have some expirience with JSP+JSTL. In self-educational purpose (and also in order to find the best solution) I want to prototype the new project with one of action-based frameworks. Actually, I will choose between Spring MVC and Stripes. Problem In order to get correct impression about action-based frameworks (in comparison with JSF) I want to be sure that I use them correctly (in bigger or lesser extent). So, here I list some most-frequent tasks (at least for me) and describe how I solve them with JSF. I want to know how they should be solved with action-based framework (or separately with Spring MVC and Stripes if there is any difference for concrete task). Rendering content: I can apply ready-to-use component from standard jsf libraries (core and html) or from 3rd-party libs (like RichFaces). I can combine simple components and I can easily create my own components which are based on standard components. Rendering data (primitive or reference types) in the correct format: Each component allow to specify a converter for transforming data in both ways (to render and to send to the server). Converter is, as usual, a simple class with 2 small methods. Site navigation: I specify a set of navigation-cases in faces-config.xml. Then I specify action-attribute of a link (or a button) which should match one or more of navigation cases. The best match is choosen by JSF. Implementing flow (multiform wizards for example): I'm using JSF 1.2 so I use Apache Orchestra for the flow (conversation) scope. Form processing: I have a pretty standard java-bean (backing bean in JSF terms) with some scope. I 'map' form fields on this bean properties. If everything goes well (no exceptions and validation is passed) then all these properties are set with values from the form fields. Then I can call one method (specified in button's action attribute) to execute some logic and return string which should much one of my navigation cases to go to the next screen. Forms validation: I can create custom validator (or choose from existing) and add it to almost each component. 3rd-party libraries have sets of custom ajax-validators. Standard validators work only after page is submitted. Actually, I don't like how validation in JSF works. Too much magic there. Many standard components (or maybe all of them) have predefined validation and it's impossible to disable it (Maybe not always, but I met many problems with it). Ajax support: many 3rd-party libraries (MyFaces, IceFaces, OpenFaces, AnotherPrefixFaces...) have strong ajax support and it works pretty well. Until you meet a problem. Too much magic there as well. It's very difficult to make it work if it doesn't work but you've done right as it's described in the manual. User-friendly URLs: people say that there are some libraries for that exist. And it can be done with filters as well. But I've never tried. It seems too complex for the first look. Thanks in advance for explaning how these items (or some of them) can be done with action-based framework.

L2S DataContext out of synch: row not found or changed

- by awrigley

The Problem I am getting a number of errors that imply that the DataContext, or rather, the way I am using the DataContext is getting out of synch. The error occurs on db.SubmitChanges() where db is my DataContext instance. The error is: Row not found or changed. The problem only occurs intermitently, for example, adding a row then deleting it. If I stop the dev server and restart, the added row is there and I can delete it no problem. Ie, it seems that the problem is related to the DataContext losing track of the rows that have been added. IMPORTANT: Before anyone votes to close this thread, on the basis of it being a duplicate, I have checked the sql server profiler and there is no "Where 0 = 1" in the SQL. I have also recreated the dbml file, so am satisfied that the database schema is in synch with the schema represented by the dbml file. Ie, no cases of mismatched nullable/not nullable columns, etc. My Diagnosis (for what it is worth): It seems to be a problem related to how I am using the DataContext. I am new to MVC, Repositories and Services patterns, so suspect that I have wired things up wrong. The Setup Simple eLearning app in its early stages. Pupils need to be able to add and delete courses (Courses table) to their UserCourses. To do this, I have a service that gets a specific DataContext instance Dependency Injected into its constructor. Service Class Constructor: public class SqlPupilBlockService : IPupilBlockService { DataContext db; public SqlPupilBlockService(DataContext db) { this.db = db; CoursesRepository = new SqlRepository<Course>(db); UserCoursesRepository = new SqlRepository<UserCourse>(db); } // Etc, etc } The CoursesRepository and UserCoursesRepository are both private properties of the service class that are of Type IRepository (just a simple generic repository interface). Sql Respoitory Code: public class SqlRepository<T> : IRepository<T> where T : class { DataContext db; public SqlRepository(DataContext db) { this.db = db; } #region IRepository<T> Members public IQueryable<T> Query { get { return db.GetTable<T>(); } } public List<T> FetchAll() { return Query.ToList(); } public void Add(T entity) { db.GetTable<T>().InsertOnSubmit(entity); } public void Delete(T entity) { db.GetTable<T>().DeleteOnSubmit(entity); } public void Save() { db.SubmitChanges(); } #endregion } The two methods for adding and deleting UserCourses are: Service Methods for Adding and Deleting UserCourses: public void AddUserCourse(int courseId) { UserCourse uc = new UserCourse(); uc.IdCourse = courseId; uc.IdUser = UserId; uc.DateCreated = DateTime.Now; uc.DateAmended = DateTime.Now; uc.Role = "Pupil"; uc.CourseNotes = string.Empty; uc.ActiveStepIndex = 0; UserCoursesRepository.Add(uc); UserCoursesRepository.Save(); } public void DeleteUserCourse(int courseId) { var uc = (UserCoursesRepository.Query.Where(x => x.IdUser == UserId && x.IdCourse == courseId)).Single(); UserCoursesRepository.Delete(uc); UserCoursesRepository.Save(); } Ajax I am using Ajax via Ajax.BeginForm I don't think that is relevant. ASP.NET MVC 3 I am using mvc3, but don't think that is relevant: the errors are related to model code.

How to Load In Content with jQuery?

- by ClarkSKent

Hello, I am trying to add ajax functionality to my pagination so the content loads in the same page instead of the user having to navigate to another page when clicking the page links. I should mention that I am using this php pagination class. Being new to jquery, I am unsure of how to properly do this with the pagination class. This is what the main page looks like: <?php $categoryId=$_GET['category']; echo $categoryId; ?> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.1/jquery.min.js"></script> <script type="text/javascript" src="jquery_page.js"></script> <?php //Include the PS_Pagination class include('ps_pagination.php'); //Connect to mysql db $conn = mysql_connect('localhost', 'root', 'root'); mysql_select_db('ajax_demo',$conn); $sql = "select * from explore where category='$categoryId'"; //Create a PS_Pagination object $pager = new PS_Pagination($conn, $sql, 3, 11, 'param1=value1&param2=value2'); //The paginate() function returns a mysql //result set for the current page $rs = $pager->paginate(); //Loop through the result set echo "<table width='800px'>"; while($row = mysql_fetch_assoc($rs)) { echo "<tr>"; echo"<td>"; echo $row['id']; echo"</td>"; echo"<td>"; echo $row['site_description']; echo"</td>"; echo"<td>"; echo $row['site_price']; echo"</td>"; echo "</tr>"; } echo "</table>"; echo "<ul id='pagination'>"; echo "<li>"; //Display the navigation echo $pager->renderFullNav(); echo "</li>"; echo "</ul>"; ?> <div id="loading" ></div> <div id="content" ></div> <a href="#" class="category" id="marketing">Marketing</a> <a href="#" class="category" id="automotive">Automotive</a> <a href="#" class="category" id="sports">Sports</a> Any help on this would be great. Thanks.

Help with Jquery and multiple forms on a page.

- by Will

I have a several forms that are output from a database on the same page. It works fine when I don't use ajax. When I use Jquery it will only work for the first form. Could anyone point me in the right direction please? Jquery..... $('.updateSubmit').live('click', function() { var id = $('.id').val(); var hardSoft = $('.hardSoft').val(); var brand = $('.brand').val(); var subCat = $('.subCat').val(); var subSubCat = $('.subSubCat').val(); var tProduct = $('.tProduct').val(); var description = $('.description').val(); var quantity = $('.quantity').val(); var price = $('.price').val(); var tCondition = $('.tCondition').val(); var featured = $('.featured').val(); var theData = 'id=' + id + '&hardSoft=' + hardSoft + '&brand=' + brand + '&subCat=' + subCat + '&subSubCat=' + subSubCat + '&tProduct=' + tProduct +'&description=' + description + '&quantity=' + quantity + '&price=' + price + '&tCondition=' + tCondition + '&featured=' + featured; $.ajax ({ type: 'POST', url: '/updateGrab.php', data: theData, success: function(aaa) { $('.'+id).append('<div class="forSuccess">'+aaa+'</div>'); } // end success }); // end ajax return false; }); // end click and my php form...... while ($row = $stmt->fetch()) { echo " <form action='http://www.wbrock.com/updateGrab.php' method='post' name='".$id."'> <input type='hidden' class='id' name='id' value='".$id."' /> Hardware/Software <input type='text' class='hardSoft' name='hardSoft' value='".$hardSoft."' /> Brand <input type='text' class='brand' name='brand' value='".$brand."' /> Sub-category <input type='text' class='subCat' name='subCat' value='".$subCat."' /> Sub-Sub-Cat <input type='text' class='subSubCat' name='subSubCat' value='".$subSubCat."' /> Product <input type='text' class='tProduct' name='tProduct' value='".$tProduct."' /> Description <input type='text' class='description' name='description' value='".$description."' /> Qty <input type='text' class='quantity' name='quantity' value='".$quantity."' /> Price <input type='text' class='price' name='price' value='".$price."' /> Cond <input type='text' class='tCondition' name='tCondition'value='".$tCondition."' /> Featured <input type='text' class='featured' name='featured' value='".$featured."' /> <input type='submit' id='".$id."' class='updateSubmit' name='updateSubmit' value='Update' /> </form> <span class='".$id."'></span> "; // end echo } // end while loop from database This is the first time I've posted here so sorry if its not in the right format. Thanks in advance for the help.
