• RichFaces demo dataTableScrollerBean.java location

  - by Mark Lewis

  Hello, I've noticed from here that the contents is only the header Revision 16532: /tags/3.3.2.SR1/samples/richfaces-demo/src/main/java/org/richfaces/demo/dataTableScroller and no listing of the dataTableScrollerBean.java file which the Edit Table/Modal Panel demo JSF code refers to. Where can I access it? I'd like to try the demo out on my machine. I've posted to RichFaces but SO tends to respond faster. Thanks Mark EDIT I've found some code (here) on a forum fortunately which is as close as I've come so far. Looks like it was written by one of the RichFaces authors, but when I included it, Eclipse is complaining about the Facet object which together with another forum and these import javax.ejb.Stateful; import javax.ejb.Stateless; suggest I may be missing j2ee.jar. But I'm running this out of Tomcat which is not an ejb container. I didn't think this RichFaces component required JBoss or equivalent so I must be doing something wrong. All I'm trying to do is try out an Edit Table! Thanks

• Perl on MacOS X 10.6.2: GDBM_File missing, how to install or work around?

  - by jdmuys

  When I need a Perl module, I typically use CPAN. It works fine. But not this time. I want to use MARC::Charset, but this one uses GDBM_File, and I can't seem to install GDBM_File from CPAN. CPAN finds it all right, but trying to install it, it starts installing the full Perl 5.10.1 distribution. MARC::Charset is a rather old module, so there should be a way to use it from some common Perl version (Mac OS X 10.6.2 has 5.10.0 and 5.8.9 by default). While installing the full blow Perl 5.10.1 is not an option, modifying MARC::Charset to stop using GDBM_File might be one. What would be the best course of action to do so? This last option might also be the only one. googling GDBM_File uncovers a few items that suggest that gdbm is not even available on the Mac. Those items typically went over my head though. While I don't expect a silver bullet, somebody may have a pointer or two on where I should start. After all, MARC::Charset only does character transliteration to/from the marc8 char set, which unfortunately, iconv doesn't seem to support.

• Sparse parameter selection using Genetic Algorithm

  - by bgbg

  Hello, I'm facing a parameter selection problem, which I would like to solve using Genetic Algorithm (GA). I'm supposed to select not more than 4 parameters out of 3000 possible ones. Using the binary chromosome representation seems like a natural choice. The evaluation function punishes too many "selected" attributes and if the number of attributes is acceptable, it then evaluates the selection. The problem is that in these sparse conditions the GA can hardly improve the population. Neither the average fitness cost, nor the fitness of the "worst" individual improves over the generations. All I see is slight (even tiny) improvement in the score of the best individual, which, I suppose, is a result of random sampling. Encoding the problem using indices of the parameters doesn't work either. This is most probably, due to the fact that the chromosomes are directional, while the selection problem isn't (i.e. chromosomes [1, 2, 3, 4]; [4, 3, 2, 1]; [3, 2, 4, 1] etc. are identical) What problem representation would you suggest? P.S If this matters, I use PyEvolve.

• jQuery AJAX slow in Firefox, fast in IE

  - by Brandon Montgomery

  I'm using jQuery to post to an ASP .NET Web Service to implement a custom auto-complete function. The code works great, except it's slow in FireFox (can't get it to go faster than 1 second). IE is blazing fast - works great. I watch the post in Firefox using Firebug. Here's the service code: <ScriptService(), _ WebService(Namespace:="http://tempuri.org/"), _ WebServiceBinding(ConformsTo:=WsiProfiles.BasicProfile1_1), _ ToolboxItem(False)> _ Public Class TestWebSvc Inherits System.Web.Services.WebService <WebMethod(), _ ScriptMethod(ResponseFormat:=Script.Services.ResponseFormat.Json, UseHttpGet:=True)> _ Public Function GetAccounts(ByVal q As String) As Object 'Code taken out for simplicity Return result End Function End Class And the jQuery ajax call: $.ajax({ beforeSend: function (req) { req.setRequestHeader("Content-Type", "application/json"); }, contentType: "application/json; charset=utf-8", type: "GET", url: "http://localhost/Suggest/TestWebSvc.asmx/GetAccounts", data: "q='" + element.val() + "'", dataType: "json", success: testWebSvcSuccess }); As you can see, I've tried to use the HTTP GET verb instead in hopes that that would make the call faster. As it does not, I'll probably switch it back to using POST if I can. Right now I'm just focused on why it's super fast in IE and super slow in Firefox. Versions: jQuery 1.3.2; Firefox 3.0.11; IE 8.0.6001.18783 (64-bit) Thank you for any insight you can provide.

• XMLOutputStream, repairing namespaces, and attributes without namespaces

  - by comment_bot

  A simple task: write an element with an unnamespaced attribute: String nsURI = "http://example.com/"; XMLOutputFactory outF = XMLOutputFactory.newFactory(); outF.setProperty(XMLOutputFactory.IS_REPAIRING_NAMESPACES, true); XMLStreamWriter out = outF.createXMLStreamWriter(System.out); out.writeStartElement(XMLConstants.DEFAULT_NS_PREFIX, "element", nsURI); out.writeAttribute(XMLConstants.DEFAULT_NS_PREFIX, XMLConstants.NULL_NS_URI, "attribute", "value"); out.writeEndElement(); out.close(); Woodstox's answer: <element xmlns="http://example.com/" attribute="value"></element> JDK 6 answer: <zdef-159241566:element xmlns="" xmlns:zdef-159241566="http://example.com/" attribute="value"></zdef-159241566:element> What?! Further, if we add a prefix to the element: out.writeStartElement(ns, "element", nsURI); JDK 6 no longer attempts to emit xmlns="": <ns:element xmlns:ns="http://example.com/" attribute="value"></ns:element> I'm fairly sure this is a bug in JDK 6. Am I right? And could anyone suggest a work around that will keep both libraries (and any others) happy? I don't want to require woodstox if I can help it.

• Custom Facelets components and attributes defined in taglib

  - by michael lucas

  Defining custom components in Facelets is easy and quick but there's one thing I can't figure out. Is it possible with Facelets to define what attributes my custom component has? I.e: I've created a component which is used in such a way: <blue:modalWindow id="editFeesWizard" width="500" height="440" title="Wizard"> and is defined in taglib.xml as follows: <!DOCTYPE facelet-taglib PUBLIC "-//Sun Microsystems, Inc.//DTD Facelet Taglib 1.0//EN" "http://java.sun.com/dtd/facelet-taglib_1_0.dtd"> <facelet-taglib> <namespace>http://blue/</namespace> <tag> <tag-name>modalWindow</tag-name> <source>components/modalWindow.xhtml</source> </tag> </facelet-taglib> Taglib doesn't contain any information on component attributes (id, width, height, title) and IDE cannot therefore check my syntax nor can it suggest attributes while I'm typing. I cannot find anything on this subject in Facelets documentation. Thought you could help. Thanks!

• The best way to package iPhone/iPad static libraries?

  - by Derek Clarkson

  Hi everyone, I have a couple of static Phone/iPad libraries I an working on. The problem I am looking for advise on is the best way to package the libraries. My objective is to make it easy to use the libraries in other projects and include the correct one in a build with minimal problems. To make it more interesting I currently build 4 versions of each library as follows armv6/armv7 release (devices) i386 release (simulator) armv6/armv7 debug (devices) i386 debug (simulator) The difference between the release and debug versions is that the debug versions contain a lot of NSLog(...) code which enables people to see whats going on internally as an aid to debugging. Currently when I build the whole projects I arrange the libraries into two directories like this: release lib-device.a lib-simulator.a debug lib-device.a lib-simulator.a This works ok except that when include in projects, both paths are added to the library search path and switching a target from one to the other is a pain. Or alternatively I end up with two targets. The alternative I am thinking of is to change the directories like this: release device lib.a simulator lib.a debug device lib.a simulator lib.a In playing with XCode is appears that all xcode uses the lbrary references of a project for is to get the name of the library file, which it then looks up in the library paths. Thus by parameterising the library path with the current built type and target device, I can effectively auto switch. What do you guys think? Is there a better way to do this? ciao Derek

• Does Google Maps API v3 allow larger zoom values ?

  - by Dr1Ku

  If you use the satellite GMapType using this Google-provided example in v3 of the API, the maximum zoom level has a scale of 2m / 10ft , whereas using the v2 version of another Google-provided example (had to use another one since the control-simple doesn't have the scale control) yields the maximum scale of 20m / 50ft. Is this a new "feature" of v3 ? I have to mention that I've tested the examples in the same GLatLng regions - so my guess is that tile detail level doesn't influence it, am I mistaken ? As mentioned in another question, v3 is to be considered of very Labs-y/beta quality, so use in production should be discouraged for the time being. I've been drawn to the subject since I have to "increase the zoom level of a GMap", the answers here seem to suggest using GTileLayer, and I'm considering GMapCreator, although this will involve some effort. What I'm trying to achieve is to have a larger zoom level, a scale of 2m / 10ft would be perfect, I have a map where the tiles aren't that hi-res and quite a few markers. Seeing that the area doesn't have hi-res tiles, the distance between the markers is really tiny, creating some problematic overlapping. Or better yet, how can you create a custom Map which allows higher zoom levels, as by the Google Campus, where the 2m / 10ft scale is achieved, and not use your own tileserver ? I've seen an example on a fellow Stackoverflower's GMaps sandbox , where the tiles are manually created based on the zoom level. I don't think I'm making any more sense, so I'm just going to end this big question here, I've been wondering around trying to find a solution for hours now. Hope that someone comes to my aid though ! Thank you in advance !

• InterIMAP, Viewing UNREAD IMAP mail and Downloading Attachments in C#

  - by Erika

  I was wondering if anyone can help me on this cause its driving me mad trying get this working I was working with the trail of mail.dll from http://www.lesnikowski.com/mail/ which is an extremely fantastic tool which unfortunately i cannot afford being a student (even though its around 150eur, its still very expensive to me :/) and this would be a small module in my thesis and my faculty cannot afford to buy these things for students either :/ so anyway I had to go for a free tool (so please dont suggest any non open source ones - trust me i have tried them ALL).. Well, i'm trying to explore InterIMAP, and for several hours have been trying to list unread emails from my gmail account but it just doesn't seem to be working. I can connect just fine but finding the unread emails seems to be no easy task.. I have tried countless approaches but non seem to give me unread emails in my inbox (I have loads of emails in my inbox and i just want the unread ones). Would someone please assist me? I have been trying to get this working for ages now, but documentation is rather lacking and my every attempt has resulted in a fail so far. Please help!! Some code i currently have: ` IMAPConfig config = new IMAPConfig("myhost", "username", "pass", true, true, ""); config.CacheFile = ""; IMAPClient client = null; try { client = new IMAPClient(config, null, 5); } catch (IMAPException e) { Console.WriteLine(e.Message); return; } Console.WriteLine(DateTime.Now.ToString()); IMAPFolder f = client.Folders["INBOX"]; IMAPSearchResult sResult = f.Search(IMAPSearchQuery.QuickSearchNew()); // <--- Gives me no results even though i do have unread messages!

• PHP: Detect encoding and make everything UTF-8

  - by marco92w

  Hello! I'm reading out lots of texts from various RSS feeds and inserting them into my database. Of course, there are several different character encodings used in the feeds, e.g. UTF-8 and ISO-8859-1. Unfortunately, there are sometimes problems with the encodings of the texts. Example: 1) The "ß" in "Fußball" should look like this in my database: "Ÿ". If it is a "Ÿ", it is displayed correctly. 2) Sometimes, the "ß" in "Fußball" looks like this in my database: "ß". Then it is displayed wrongly, of course. 3) In other cases, the "ß" is saved as a "ß" - so without any change. Then it is also displayed wrongly. What can I do to avoid the cases 2 and 3? How can I make everything the same encoding, preferably UTF-8? When must I use utf8_encode(), when must I use utf8_decode() (it's clear what the effect is but when must I use the functions?) and when must I do nothing with the input? Can you help me and tell me how to make everything the same encoding? Perhaps with the function mb-detect-encoding()? Can I write a function for this? So my problems are: 1) How to find out what encoding the text uses 2) How to convert it to UTF-8 - whatever the old encoding is Thanks in advance! EDIT: Would a function like this work? function correct_encoding($text) { $current_encoding = mb_detect_encoding($text, 'auto'); $text = iconv($current_encoding, 'UTF-8', $text); return $text; } I've tested it but it doesn't work. What's wrong with it?

• Pseudocode help

  - by vatsag

  Hello All I've been banging my head over few hours for realising this particular logic My task is to have a masterlist ListM elements of which shall be list(again) in the form of ListA(type A) and ListB(type B) and ListC(type C)(some generic type). Also the lists A and ListB can contain elements of type C(some generic type). Coming to the preconditions 1. ListA can contain only 50 elements of type 'A', rest of the elements can be of generic type C 2. ListB can contain only 50 elements of type 'B', rest of the elements can be of generic type C 3. Also the lists(ListA or ListB) can take at max of 100 elements. 4. ListC can contain elements of generic type C and can take max of 100 elements For ex: Now, If i have 200 elements of type A and 200 elements of type B and 600 elements of type C then i should be able to get 4 Lists(50 elements in each list) of type...ListA (because each ListA can contain at max of 50 elements of type A only, rem 50 is typeC) 4 Lists(50 elements in each list) of type...ListB (because each ListA can contain at max of 50 elements of type B only, rem 50 is typeC) 2 Lists(50 elements in each list) of type...ListC i shall be glad to explain it again if my explanation is quite confusing. Can anyone suggest a better way for implementing such a requirement in the form of a pseudocode ? Thanks in advance VATSAG

• Status of VB6/ Best Desktop Application Language with Native Compilation

  - by Sandeep Jindal

  I was looking for a Desktop Application Programming Language with one of the biggest constraint: - “I need to output as native executable”. I explored multiple options: Java is not a very good option for desktop programming, but still you can use it. But Java to Exe is a problem. Only GCJ and Excelsior-Jet provides this. .Net platform does not support native compilation. Only very few expensive tools are available which can do the job. Python is not an option for native compilation. Right? VB6 is the option I am left with. From the above list, if I am correct, VB6 is the only and probably the best option I have. But VB6 itself has issues like: It is no more under development since There are questions on support of VB6 IDE with Vista Thus my questions are: From the list of programming language options, do you want to add any more? If VB6 is good/best option, looking at its development status, would you suggest using VB6 in this era?

• How to set the tableview's top using contentinset property while being at the bottom of the table

  - by neha

  Hi all, I'm having a tableview with 20 rows and 250 as their rowheight. While I'm at the bottom of the tableview, I want to shift the tableview upwards by 65px. I tried doing self.tableView.contentInset = UIEdgeInsetsMake(-65.0f, 0.0f, 0.0f, 0.0f); Also self.tableView.contentInset = UIEdgeInsetsMake((4633.0f - 65.0f), 0.0f, 0.0f, 0.0f); where 4633.0f is my contentoffset.y, but with no success. When the last cell is pulled upwards, I'm showing a view below the last cell with an activity indicator on it to depict that more data is getting loaded. I need to keep that view visible for 2 seconds so I want to push the tableview cells up and after that I want to bring the tableview to its original position and reset the view below that. I'm doing this [UIView beginAnimations:nil context:NULL]; [UIView setAnimationDuration:0.2]; // self.tableView.contentInset = UIEdgeInsetsMake((4633.0f - 65.0f), 0.0f, 0.0f, 0.0f); self.tableView.contentInset = UIEdgeInsetsMake(- 65.0f, 0.0f, 0.0f, 0.0f); [UIView commitAnimations]; and then calling a function to reset it back as self.tableView.contentInset = UIEdgeInsetsMake(0.0f, 0.0f, 0.0f, 0.0f); Can anybody please suggest how to do it? Thanx in advance.

• Telerik MVC Combobox AutoComplete error

  - by Roachmans

  I am using the Telerik autocomplete option In the header: <script type="text/javascript"> function onAutoCompleteDataBinding(e) { var autocomplete = $('#AutoComplete').data('tAutoComplete'); autocomplete.dataBind(["Product 1", "Product 2", "Product 3"]} </script> In the body of the View: <%=Html.Telerik().AutoComplete() .Name("AutoComplete") .ClientEvents(events => events.OnDataBinding("onAutoCompleteDataBinding")) %> http://demos.telerik.com/aspnet-mvc/combobox/clientsidebinding I have managed to get this working on other applications and it is really quite simple. I have pasted this example on top to show that this one also bombs out on : this.trigger = new $t.list.trigger(this); Think i might have mixed up the .js files and now my auto complete is not working. Any sugesions which js files and in what order they must be for this to work right My Page master relevant parts: <body> <% Html.Telerik().ScriptRegistrar() .DefaultGroup(group => group .Add("MicrosoftAjax.js") .Add("MicrosoftMvcAjax.js") ); %> <div class="MainTableBody"> <asp:ContentPlaceHolder ID="ContentPlaceHolder" runat="server" /> </div> <% Html.Telerik().ScriptRegistrar().Render(); %> </body> </html> In my web.config <add namespace="Telerik.Web.Mvc.UI" /> Any help or comments would be greatly appreciated

• Drupal image management

  - by vian

  Please suggest how should I approach these requirements. What ready-to-use solutions (modules) are best suited to achieve something like this: What I need is an image library that has searchable, tagged images that are already resized when we publish them. If the author searches the library and the image he needs isn’t there, he can upload one and have it added to the index. The important thing is that images in the library can be sorted into three categories: News images, top story images and feature images so that, over time, we don’t end up with hundreds of images crammed into one folder, thus making browsing a pain (and to prevent someone from something like: Searching for a keyword so they can find an image for the news, picking an image, and then seeing it’s 1600X. 1200). Also, I need something which will assemble thumbnail galleries easily. I don’t want to have to go to the image library, get a URL, go back, paste it in, etc. I should be able to pick, say, 8 images and say “create gallery”. How this objective is achieved is flexible, but I am looking for a shortcut to get around assembling screenshot galleries by hand.

• Building Cross Platform app - recommendation

  - by Ben

  Hi, I need to build a fairly simple app but it needs to work on both PC and Mac. It also needs to be redistributable on a disc or usb drive as a standalone desktop app. Initially I thought AIR would be perfect for this (it ticks all the API requirements), but the difficulty is making it distributable, as the app would require the AIR runtime to be installed to run. I came across Shu Player as an option as it seems to be able to package the AIR runtime with the app and do a (silent?) install. However this seems to break the T&C from Adobe (as outlined here) so I'm not sure about the legality. Another option could be Zinc but I haven't tested it so I'm not sure how well it'll fit the bill. What would you recommend or suggest I check out? Any suggestion much appreciated EDIT: There's a few more discussions on mono usage (though no real conclusion): Here and Here EDIT2: Titanium could also fit the bill maybe, will check it out. Any more comments from anyone? Ben

• Scroll Position in a Table Body

  - by Craig Walker

  I want to implement infinite scrolling (with an AJAX-based loader) in an HTML table body. My HTML looks something like this: <table> <thead> <tr><th>Column</th></tr> </thead> <tbody> <tr><td>Row 1</td></tr> <tr><td>Row 2</td></tr> </tbody> </table> I get a scroll bar on the <tbody> like so: tbody { height:10em; /* Otherwise the tbody expands to fit all rows */ overflow:auto; } To be able to do anything when the user scrolls to the bottom, I need to be able to get the scroll position of the <tbody>. In all of the (jQuery) infinite scroll implementations I've seen (such as this one), they subtract the content height from the container height and compare it to the .scrollTop() value. Unfortunately this may not work with <tbody>, which is both the viewport and the container for the scrolled content. $("tbody").height() returns the viewable (ie: "shrunken") size, but I don't know how I can get the full (viewable + hidden) size of the table body. (FWIW, $("tbody").scrollTop() returns a "large" number when scrolled to the bottom, exactly as I would expect it to). Is there any way to accomplish this?

• Hibernate: OutOfMemoryError persisting Blob when printing log message

  I have a Hibernate Entity: @Entity class Foo { //... @Lob public byte[] getBytes() { return bytes; } //.... } My VM is configured with a maximum heap size of 512 MB. When I try to persist an object which has a 75 MB large object, I get an OutOfMemoryError. The names of the methods in the stack trace (StringBuilder, ByteArrayBlobType.toLoggableString, pretty.Printer.toString) suggest that hibernate is trying to write a very large log message that contains my object.

• Getting chart data to work within a function

  - by StealthRT

  Hey all i am in need of some help trying to figure out how to pass a string into an array field for a chart. The chart i am using is this [http://www.highcharts.com/] Here is the chart code: function drawChart(theDATA) { var chart = new Highcharts.Chart({ chart: {renderTo: 'container',defaultSeriesType: 'column'}, title: {text: 'March 2010 Confirmed User Visit\'s'}, xAxis: {categories: ['1','2','3','4','5','6','7','8','9','10','11','12','13','14','15','16','17','18','19','20','21','22','23','24','25','26','27','28','29','30','31']}, yAxis: {min: 0,title: {text: 'User Visit\'s'}}, legend: {layout: 'vertical',backgroundColor: '#FFFFFF',style: {left: '100px',top: '70px',bottom: 'auto'}}, tooltip: {formatter: function() {return this.y;}}, plotOptions: {column: {pointPadding: 0.2,borderWidth: 0}}, series: [{name: 'Confirmed Users Visit\'s', data: [theDATA] }] }); } With the code above, you would think that theDATA would work but it does not display the data within it. Say that theDATA is '2,5,4,7,8,9'. If i had this: data: [2,5,4,7,8,9] Then it would work just fine. But if i use those same numbers... theData = "2,5,4,7,8,9" data: [theData] It does nothing on the chart... So what am i doing wrong???? David

• HtmlAgilityPack giving problems with malformed html

  I want to extract meaningful text out of an html document and I was using html-agility-pack for the same. Here is my code: string convertedContent = HttpUtility.HtmlDecode(ConvertHtml(HtmlAgilityPack.HtmlEntity.DeEntitize(htmlAsString))); ConvertHtml: public string ConvertHtml(string html) { HtmlDocument doc = new HtmlDocument(); doc.LoadHtml(html); StringWriter sw = new StringWriter(); ConvertTo(doc.DocumentNode, sw); sw.Flush(); return sw.ToString(); } ConvertTo: public void ConvertTo(HtmlAgilityPack.HtmlNode node, TextWriter outText) { string html; switch (node.NodeType) { case HtmlAgilityPack.HtmlNodeType.Comment: // don't output comments break; case HtmlAgilityPack.HtmlNodeType.Document: foreach (HtmlNode subnode in node.ChildNodes) { ConvertTo(subnode, outText); } break; case HtmlAgilityPack.HtmlNodeType.Text: // script and style must not be output string parentName = node.ParentNode.Name; if ((parentName == "script") || (parentName == "style")) break; // get text html = ((HtmlTextNode)node).Text; // is it in fact a special closing node output as text? if (HtmlNode.IsOverlappedClosingElement(html)) break; // check the text is meaningful and not a bunch of whitespaces if (html.Trim().Length > 0) { outText.Write(HtmlEntity.DeEntitize(html) + " "); } break; case HtmlAgilityPack.HtmlNodeType.Element: switch (node.Name) { case "p": // treat paragraphs as crlf outText.Write("\r\n"); break; } if (node.HasChildNodes) { foreach (HtmlNode subnode in node.ChildNodes) { ConvertTo(subnode, outText); } } break; } } Now in some cases when the html pages are malformed (for example the following page - http://rareseeds.com/cart/products/Purple_of_Romagna_Artichoke-646-72.html has a malformed meta-tag like <meta content="text/html; charset=uft-8" http-equiv="Content-Type">) [Note "uft" instead of utf] my code is puking at the time I am trying to load the html document. Can someone suggest me how can I overcome these malformed html pages and still extract relevant text out of a html document? Thanks, Kapil

  - by Bas Bossink

  In the project I'm currently working on there is a need to save a sizeable data structure to disk. Being in optimist I thought their must be a standard solution for such a problem however upto now I haven't found a solution that satisfies the following requirements: .net 2.0 support, preferably with a foss implementation version friendly (this should be interpreted as reading an old version of the format should be relatively simple if the changes in the underlying data structure are simple, say adding/dropping fields) ability to do some form of random access where part of the data can be extended after initial creation (think of this as extending intermediate results) space and time efficient (xml has been excluded as option given this requierement) Options considered so far: Protocol Buffers : was turned down by verdict of the documentation about Large Data Sets since this comment suggest adding another layer on top, this would call for additional complexity which I wish to have handled by the file format itself. HDF5,EXI : do not seem to have .net implementations SQLite : the data structure at hand would result in a pretty complex table structure that seems to heavyweight for the intended use BSON : does not appear to support requirement 3. Fast Infoset : only seems to have buyware .net implementations Any recommendations or pointers are greatly appreciated. Furthermore if you believe any of the information above is not true please provide pointers/examples to proove me wrong.

  - by BibiBuBu

  Good Day! i have a question that how can i use animation extender in datalist control in asp.net with c#. i want the animation when i click the delete button (delete button will be in repeater). so that when i remove one record then it shows animation to bring the next record. it is in update panel. <cc1:AnimationExtender ID="AnimationExtender1" runat="server" Enabled="True" TargetControlID="btnDeleteId"> <Animations> <OnClick> <Sequence> <EnableAction Enabled="false" /> <Parallel Duration=".2"> <Resize Height="0" Width="0" Unit="px" /> <FadeOut /> </Parallel> <HideAction /> </Sequence> </OnClick> </Animations> </cc1:AnimationExtender> now if i put my button id in the Target control id then it gives error that it should not be in same update panel etc... but over all nothing working for animation. i am binding my datalist in itemDataBound....e.g. ImageButton imgbtn = (ImageButton)e.Item.FindControl("imgBtnPic"); Label lblAvatar = (Label)e.Item.FindControl("lblAvatar"); LinkButton lbName = (LinkButton)e.Item.FindControl("lbtnName"); Can somebody please suggest me something. thanks

• JavaScript call to page method: error 500. JSON

  - by Ryan Ternier

  I'm using the auto complete control here:http://www.ramirezcobos.com/labs/autocomplete-for-jquery-js/comment-page-2/ And i've modified it as: var json_options; json_options = { script:'ReportSearch.aspx/GetUserList?json=true&limit=6&', varname:'input', json:true, shownoresults:true, maxresults:16, callback: function (obj) { $('#json_info').html('you have selected: '+obj.id + ' ' + obj.value + ' (' + obj.info + ')'); } }; $('#ctl00_contentModule_txtJQuerySearch').autoComplete(json_options); I have the following method in C# Code behind (aspx.cs) [System.Web.Services.WebMethod] [System.Web.Script.Services.ScriptMethod] public static string[] GetUserList(string input) { List<string> lUsers = new List<string>(); Server.DAL.SQLServer2005.User user = new Server.DAL.SQLServer2005.User(); Server.Info.AuthUser aUser = (Server.Info.AuthUser)HttpContext.Current.Session["AuthUser"]; List<Server.Info.User.UserDetails> users = user.GetUserList(aUser, input, 16, true); users.ForEach(delegate(ReportBeam.Server.Info.User.UserDetails u) { lUsers.Add("(" + u.UserName + ")" + u.LastName + ", " + u.FirstName); }); return lUsers.ToArray(); } The error I get back is: Server Error in '/WebPortal4' Application. Unknown web method GetUserList. Parameter name: methodName If I change any of the paraemeter names I get an error telling me the paremeter names are not in match. now that everything is as it should, it's bombing. Any help would rock.
