  • Jquery UI modal dialogs

    - by Anonymous user
    Hi All. I have a problem with Jquery UI modal dialogs. I have modal dialog (dialogA), which can create another modal dialog (dialogB). After the second creation and closure of the dialogB the overlay of dialogA disappear. Here is my code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" > <head><link type="text/css" rel="Stylesheet" href="ui-lightness/jquery-ui-1.8.custom.css" /> <script type="text/javascript" src="jquery-1.4.2.min.js"></script> <script type="text/javascript" src="jquery-ui-1.8.custom.min.js"></script> <script type="text/javascript"> function createDialog(dialogId) { $('#' + dialogId).dialog({ autoOpen: true, modal: true, buttons: { 'close': function() { $(this).dialog('close'); }, 'create': function() { var newDialogId = dialogId + '1'; $('body').append('<div id="' + newDialogId + '">' + newDialogId + '</div>'); createDialog(newDialogId); } }, close: function() { $(this).dialog('destroy'); $(this).remove(); } }); } $(document).ready(function() { $('#button1').click(function() { var dialogId = 'dialog'; $('body').append('<div id="' + dialogId + '">' + dialogId + '</div>'); createDialog(dialogId); }); }); </script> </head> <body> <button id="button1">Create dialog</button> </body> </html> Thanks

  • dynamically created arrays

    - by DevAno1
    My task consists of two parts. First I have to create globbal char array of 100 elements, and insert some text to it using cin. Afterwards calculate amount of chars, and create dedicated array with the length of the inputted text. I was thinking about following solution : char[100]inputData; int main() { cin >> inputData >> endl; int length=0; for(int i=0; i<100; i++) { while(inputData[i] == "\0") { ++count; } } char c = new char[count]; Am I thinking good ? Second part of the task is to introduce in the first program dynamically created array of pointers to all inserted words. Adding a new word should print all the previous words and if there is no space for next words, size of the inputData array should be increased twice. And to be honest this is a bit too much for me. How I can create pointers to words specifically ? And how can I increase the size of global array without loosing its content ? With some temporary array ?

  • Fast, very lightweight algorithm for camera motion detection?

    - by Ertebolle
    I'm working on an augmented reality app for iPhone that involves a very processor-intensive object recognition algorithm (pushing the CPU at 100% it can get through maybe 5 frames per second), and in an effort to both save battery power and make the whole thing less "jittery" I'm trying to come up with a way to only run that object recognizer when the user is actually moving the camera around. My first thought was to simply use the iPhone's accelerometers / gyroscope, but in testing I found that very often people would move the iPhone at a consistent enough attitude and velocity that there wouldn't be any way to tell that it was still in motion. So that left the option of analyzing the actual video feed and detecting movement in that. I got OpenCV working and tried running their pyramidal Lucas-Kanade optical flow algorithm, which works well but seems to be almost as processor-intensive as my object recognizer - I can get it to an acceptable framerate if I lower the depth levels / downsample the image / track fewer points, but then accuracy suffers and it starts to miss some large movements and trigger on small hand-shaking-y ones. So my question is, is there another optical flow algorithm that's faster than Lucas-Kanade if I just want to detect the overall magnitude of camera movement? I don't need to track individual objects, I don't even need to know which direction the camera is moving, all I really need is a way to feed something two frames of video and have it tell me how far apart they are.

  • Running ASP / ASP.NET markup outside of a web application (perhaps with MVC)

    - by Frank Schwieterman
    Is there a way to include some aspx/ascx markup in a DLL and use that to generate text dynamically? I really just want to pass a model instance to a view and get the produced html as a string. Similar to what you might do with an XSLT transform, except the transform input is a CLR object rather than an XML document. A second benefit is using the ASP.NET code-behind markup which is known by most team members. One way to achieve this would be to load the MVC view engine in-process and perhaps have it use an ASPX file from a resource. It seems like I could call into just the ViewEngine somehow and have it generate a ViewEngineResult. I don't know ASP.NET MVC well enough though to know what calls to make. I don't think this would be possible with classic ASP or ASP.NET as the control model is so tied to the page model, which doesn't exist in this case. Using something like SparkViewEngine in isolation would be cool too, though not as useful since other team members wouldn't know the syntax. At that point I might as well use XSLT (yes I am looking for a clever way to avoid XSLT).

  • How do I find, count, and display unique elements of an array using Perl?

    - by Luke
    I am a novice Perl programmer and would like some help. I have an array list that I am trying to split each element based on the pipe into two scalar elements. From there I would like to spike out only the lines that read ‘PJ RER Apts to Share’ as the first element. Then I want to print out the second element only once while counting each time the element appears. I wrote the piece of code below but can’t figure out where I am going wrong. It might be something small that I am just overlooking. Any help would be greatly appreciated. ## CODE ## my @data = ('PJ RER Apts to Share|PROVIDENCE', 'PJ RER Apts to Share|JOHNSTON', 'PJ RER Apts to Share|JOHNSTON', 'PJ RER Apts to Share|JOHNSTON', 'PJ RER Condo|WEST WARWICK', 'PJ RER Condo|WARWICK'); foreach my $line (@data) { $count = @data; chomp($line); @fields = split(/\|/,$line); if (($fields[0] =~ /PJ RER Apts to Share/g)){ @array2 = $fields[1]; my %seen; my @uniq = grep { ! $seen{$_}++ } @array2; my $count2 = scalar(@uniq); print "$array2[0] ($count2)","\n" } } print "$count","\n"; ## OUTPUT ## PROVIDENCE (1) JOHNSTON (1) JOHNSTON (1) JOHNSTON (1) 6

  • I write barely functional scripts that tend to not be resuable and make the baby jesus cry. Please h

    - by maxxpower
    I received a request to add around 100 users to a linux box the users are already in ldap so I can't just use newusers and point it at a text file. Another admin is taking care of the ldap piece so all I have to do is create all the home directories and chown them to the correct user once he adds the users to the box. creating the directories isn't a problem, but I'd like a more elegant script for chowning them to the correct user. what I have currently basically looks like chown -R testuser1 testgroup1 /home/tetsuser1; chown -R testuser2 testgroup2 /home/testgroup2; chown -R testsuser3 testgroup1 /home/testuser3 bascially I took the request that the user name and group name popped it into excel added a column of "chown -R" to the front, then added a column of "/", copied and pasted the username column after it and then added a column of ";" and dragged it down to the second to last row. Popped it into notepad ran some quick find and replaces and in less than a minute I have a completed request and a sad empty feeling. I know this was a really ghetto method and I'm trying to get away from using excel to avoid learning new scripting techniques so here's my real question. tl;dr I made 100 home directories and chowned them to the correct users, but it was ugly. Actual question below. You have a file named idlist that looks like this (only with say 1000 users and real usernames and groups) testuser1 testgroup1 testuser2 testgroup2 testuser3 testgroup1 write a script that creates home directories for all the users and chowns the created directories to the correct user and group. To make the directories I used the following(feel free to flame/correct me on this as well. ) var= 'cut -f1 -d" " idlist' (I used backticks not apostrophes around the cut command) mkdir $var

  • Retrieving dll version info via Win32 - VerQueryValue(...) crashes under Win7 x64

    - by user256890
    The respected open source .NET wrapper implementation (SharpBITS) of Windows BITS services fails identifying the underlying BITS version under Win7 x64. Here is the source code that fails. NativeMethods are native Win32 calls wrapped by .NET methods and decorated via DllImport attribute. private static BitsVersion GetBitsVersion() { try { string fileName = Path.Combine( System.Environment.SystemDirectory, "qmgr.dll"); int handle = 0; int size = NativeMethods.GetFileVersionInfoSize(fileName, out handle); if (size == 0) return BitsVersion.Bits0_0; byte[] buffer = new byte[size]; if (!NativeMethods.GetFileVersionInfo(fileName, handle, size, buffer)) { return BitsVersion.Bits0_0; } IntPtr subBlock = IntPtr.Zero; uint len = 0; if (!NativeMethods.VerQueryValue(buffer, @"\VarFileInfo\Translation", out subBlock, out len)) { return BitsVersion.Bits0_0; } int block1 = Marshal.ReadInt16(subBlock); int block2 = Marshal.ReadInt16((IntPtr)((int)subBlock + 2 )); string spv = string.Format( @"\StringFileInfo\{0:X4}{1:X4}\ProductVersion", block1, block2); string versionInfo; if (!NativeMethods.VerQueryValue(buffer, spv, out versionInfo, out len)) { return BitsVersion.Bits0_0; } ... The implementation follows the MSDN instructions by the letter. Still during the second VerQueryValue(...) call, the application crashes and kills the debug session without hesitation. Just a little more debug info right before the crash: spv = "\StringFileInfo\040904B0\ProductVersion" buffer = byte[1900] - full with binary data block1 = 1033 block2 = 1200 I looked at the targeted "C:\Windows\System32\qmgr.dll" file (The implementation of BITS) via Windows. It says that the Product Version is 7.5.7600.16385. Instead of crashing, this value should return in the verionInfo string. Any advice?

  • Need variable width negative lookbehind replacement

    - by Technoh
    I have looked at many questions here (and many more websites) and some provided hints but none gave me a definitive answer. I know regular expressions but I am far from being a guru. This particular question deals with regex in PHP. I need to locate words in a text that are not surrounded by a hyperlink of a given class. For example, I might have This <a href="blabblah" class="no_check">elephant</a> is green and this elephant is blue while this <a href="blahblah">elephant</a> is red. I would need to match against the second and third elephants but not the first (identified by test class "no_check"). Note that there could more attributes than just href and class within hyperlinks. I came up with ((?<!<a .*class="no_check".*>)\belephant\b) which works beautifully in regex test software but not in PHP. Any help is greatly appreciated. If you cannot provide a regular expression but can find some sort of PHP code logic that would circumvent the need for it, I would be equally grateful.

  • SQL Server search filter and order by performance issues

    - by John Leidegren
    We have a table value function that returns a list of people you may access, and we have a relation between a search and a person called search result. What we want to do is that wan't to select all people from the search and present them. The query looks like this SELECT qm.PersonID, p.FullName FROM QueryMembership qm INNER JOIN dbo.GetPersonAccess(1) ON GetPersonAccess.PersonID = qm.PersonID INNER JOIN Person p ON p.PersonID = qm.PersonID WHERE qm.QueryID = 1234 There are only 25 rows with QueryID=1234 but there are almost 5 million rows total in the QueryMembership table. The person table has about 40K people in it. QueryID is not a PK, but it is an index. The query plan tells me 97% of the total cost is spent doing "Key Lookup" witht the seek predicate. QueryMembershipID = Scalar Operator (QueryMembership.QueryMembershipID as QM.QueryMembershipID) Why is the PK in there when it's not used in the query at all? and why is it taking so long time? The number of people total 25, with the index, this should be a table scan for all the QueryMembership rows that have QueryID=1234 and then a JOIN on the 25 people that exists in the table value function. Which btw only have to be evaluated once and completes in less than 1 second.

  • ploting 3d graph in matlab?

    - by lytheone
    Hello, I am currently a begineer, and i am using matlab to do a data analysis. I have a a text file with data at the first row is formatted as follow: time;wave height 1;wave height 2;....... I have column until wave height 19 and rows total 4000 rows. Data in the first column is time in second. From 2nd column onwards, it is wave height elevation which is in meter. At the moment I like to ask matlab to plot a 3d graph with time on the x axis, wave elevation on the y axis, and wave elevation that correspond to wave height number from 1 to 19, i.e. data in column 2 row 10 has a let say 8m which is correspond to wave height 1 and time at the column 1 row 10. I have try the following: clear; filename='abc.daf'; path='C:\D'; a=dlmread([path '\' filename],' ', 2, 1); [nrows,ncols]=size(a); t=a(1:nrows,1);%define t from text file for i=(1:20), j=(2:21); end wi=a(:,j); for k=(2:4000), l=k; end r=a(l,:); But everytime i use try to plot them, the for loop wi works fine, but for r=a(l,:);, the plot only either give me the last time data only but i want all data in the file to be plot. Is there a way i can do that. I am sorry as it is a bit confusing but i will be very thankful if anyone can help me out. Thank you!!!!!!!!!!

  • JS sort works in Firefox but not IE - can't work out why

    - by Max Williams
    I have a line in a javascript function that sort an array of objects based on the order of another array of strings. This is working in firefox but not in IE and i don't know why. Here's what my data looks like going into the sort call. (I'm using an array of three items just to illustrate the point here). //cherry first then the rest in alphabetical order originalData = ['cherry','apple','banana','clementine','nectarine','plum'] //data before sorting - note how clementine is second item - we wan to to to be after apple and banana csub = [ {"value":"cherry","data":["cherry"],"result":"cherry"}, {"value":"clementine","data":["clementine"],"result":"clementine"}, {"value":"apple","data":["apple"],"result":"apple"}, {"value":"banana","data":["banana"],"result":"banana"}, {"value":"nectarine","data":["nectarine"],"result":"nectarine"}, {"value":"plum","data":["plum"],"result":"plum"} ] //after sorting, csub has been rearranged but still isn't right: clementine is before banana csubSorted = [ {"value":"cherry","data":["cherry"],"result":"cherry"}, {"value":"apple","data":["apple"],"result":"apple"}, {"value":"clementine","data":["clementine"],"result":"clementine"}, {"value":"banana","data":["banana"],"result":"banana"}, {"value":"nectarine","data":["nectarine"],"result":"nectarine"}, {"value":"plum","data":["plum"],"result":"plum"} ] Here's the actual sort code: csubSorted = csub.sort(function(a,b){ return (originalData.indexOf(a.value) > originalData.indexOf(b.value)); }); Can anyone see why this wouldn't work? Is the basic javascript sort function not cross-browser compatible? Can i do this a different way (eg with jquery) that would be cross-browser? grateful for any advice - max

  • Custom Jquery slideshow doesn't want to reset?

    - by Jared
    Hello, Under $(document).ready(function(), I have the following code: num = $("#mainContentCategoryLinksWrapper > div").size(); This makes num equal the length of the children of #mainContentCategoryLinksWrapper. Currently, this equals 4. Above the $(document).ready(function( I have this: var timesRun = 0; function slideshow(){ if(timesRun < num){ $(".arrowIn").stop().animate({color: "#a12324", textIndent: "30px", backgroundPosition: '0px 0px'}, 100, function(){ //the first child in the series has a class of "arrowIn" $(".arrowIn").next().addClass("replaceMe"); //Adds the ".replaceMe" placeholder the the next element. $(".arrowIn").removeClass("arrowIn"); //Deletes the class on the current element $(".replaceMe").addClass("arrowIn").removeClass("replaceMe"); //reassigns ".arrowIn" over ".replaceMe" timesRun = timesRun + 1; //increases number of times run }).prev().animate({color: "#000000", textIndent: "25px", backgroundPosition: '0px -25px'}, {duration: 50}); //puts the previous element back to it's original position }else{ timesRun = 0; $(".arrowIn").removeClass("arrowIn"); $("#mainContentCategoryLinksWrapper:first-child").addClass("arrowIn"); //this is supposed to reset timesRun, and set the first child in the series back to the original ".arrowIn" } } setInterval( 'slideshow()', 1000 ); So here is the what the code does: 1) Animates the first in the series of 4 (#1) timesRun = 1 2) Animates the second in the series of 4 (#2) timesRun = 2 3) Animates the third in the series of 4 (#3) timesRun = 3 4) Animates the fourth in the series of 4 (#4) timesRun = 4 5) timesRun is now longer less than num. Reset class names back to original to .arrowIn, set timesRun to 0. However, when the slideshow() is reexectuted, it doesn't start over. Any ideas? See www.raceramps.com/v3 for an example.

  • PHP regex - find and replace

    - by jay
    Hi, I am trying to do this regex match and replace but not able to do it. Example <SPAN class="one">first content here</SPAN> <SPAN class="two">second content here </SPAN> <SPAN class="three">one; two; three; and more.</span> <SPAN class="four">more content here.</span> I want to find each set of the span tags and replace with something like this Find <SPAN class="one">first content here</SPAN> Change to <one>first content here</one> same way the the rest of the span tags. class="one", class="two" and so on are the only key identifier which I use in the regex match expression. So if I find a span tag with these class then I want to do the replace. My main issue is that I am not able to find the occurrence of first closing tag so what it does is it finds from the start to end which is of no use. So far I have been trying to do this using notepad++ but just found that it has its limitations so any php help would be appreciated. regards

  • updating system's time using .Net

  • WPF: How to connect to a sql ce 3.5 database with ADO.NET?

    - by EV
    Hi, I'm trying to write an application that has two DataGrids - the first one displays customers and the second one selected customer's records. I have generated the ADO.NET Entity Model and the connection property are set in App.config file. Now I want to populate the datagrids with the data from sql ce 3.5 database which does not support LINQ-TO-SQL. I used this code for the first datagrid in code behind: CompanyDBEntities db; private void Window_Loaded(object sender, RoutedEventArgs e) { db = new CompanyDBEntities(); ObjectQuery<Employees> departmentQuery = db.Employees; try { // lpgrid is the name of the first datagrid this.lpgrid.ItemsSource = departmentQuery; } catch (Exception ex) { MessageBox.Show(ex.Message); } However, the datagrid is empty although there are records in a database. It would also be better to use it in MVVM pattern but I'm not sure how does the ado.net and MVVM work together and if it is even possible to use them like that. Could anyone help? Thanks in advance.

  • How to generate an ear file from a maven-archetype-webapp artifact?

    - by Mike
    I currently have a project built with maven-archetype-webapp artifact. The default packaging for this project is war. Is it possible for me to insert the maven-ear-plugin in this webapp pom.xml generate an ear file that contains this project war? I tried that, but the war file doesn't get embedded in the generated ear file. It has everything except the war file. I read many Maven related articles, and perhaps I could use maven-archetype-j2ee-simple artifact. However, I'm reluctant to this use for 2 reasons:- This artifact handles ejbs and all the extra features that I don't use. It makes my project looks bloated. Second, it seems like it requires me to install the web module into the repository first before I can create the ear file. Is this the preferred way to create an ear file? How do I create an ear file that contains the war file using maven-ear-plugin from my webapp's pom.xml? If this way is not possible, what's the preferred way? I'm sorry if my questions sound a little novice, I realized I have whole lot more to learn about Maven. Thanks much.

  • Linking Listbox child categories

    - by Gerardo Abdo
    Hello I have few monhts working with aspx, and now I'm developing a shopping cart website. For the employee to upload the products on the DB, every product needs to be linked to a category and sub category, and sub-sub category, and so on. Sometimes the sub-sub categories are up to 5. For example Electronics-TV-LCD-Samsung-40 inches. First, What I would like to identify is if the SQL table has the apporpiate structure. I have 3 columns Id, Description, Parent_Id. Categories with Parent Id=0 is used for the top ones. Is this the best way to do it? Then I want to use the ListBox control to select main Categories, and once it is selected, filled a second listbox with its childs and so on. Do I need to query SQL DB everytime the change event happens? I heard about linq but have not used yet, What would be your suggestion to do this. If you have seen a sample to understand it better will be appreciated. Thank you

  • VBA compare and sort strings with quirky characters

    - by Smandoli
    I am comparing text values from two DAO recordsets in MS Access. I sort on the text field, then go through both recordsets comparing the values from each. The sets are substantially different and while they're mostly alpha-numeric, spaces and symbols like hyphens and periods are very common. My program depends on predictable sorting and fool-proof comparing. But unfortunately, the sort will rank two values differently than the comparison function. StrComp is the obvious first choice: varResult = StrComp(Val_1, Val_2) RFA-300 14.9044 RFA300 14-2044 But for the two pairs above, StrComp returns a different value than one would expect based on the sort. Including vbTextCompare or vbBinaryCompare affects StrComp's result, but not so as to solve the problem. Note the values must always be compared as strings. Of course I make sure that "14-2044" and "14.9044" aren't evaluated as -2030 and ~15. That's not the cause of my problem. I learned API-based functions are more reliable for quirky texts, so I tried these: varResult = CompareString(LOCALE_SYSTEM_DEFAULT, _ SORT_STRINGSORT, strVal_2, -1, strVal_1, -1) varResult = CompareString(LOCALE_SYSTEM_DEFAULT, _ NORM_IGNOREWIDTH, strVal_2, -1, strVal_1, -1) The first one returns the opposite of StrComp. The second one returns the same as StrComp. But neither yields a result that is consistent with the sort order. (NORM_IGNOREWIDTH is probably not relevant, but I needed a place-holder substitute and it looked as good as any.) UPDATE: This is a complete rewrite of the original post, deleting all the info about why I really need this -- just take my word for it and enjoy the brevity.

  • ExternalInterface issue on loadup with FireFox

    - by Rudy
    Hello, I have an issue with my ExternalInterface. The way it is currently set up is, on the page load up, a boolean is set to true in JavaScript and then checked by ActionScript constructors (using a timer) until it is true. This marks that JavaScript is ready to get calls from AS3. At this point, AS3 will add the callback and do some internal stuff, and at the end of the constructor I call JavaScript. So far so good. JavaScript will at this point call a function in AS3 (that was defined in the callback described above), and this is where it all messes up. On IE this works perfectly fine. On FireFox though, it does not. When I debug it, I see that the javascript function is called but when it tries to call AS3, nothing happens. I also tried to add a timer, but for some reason the function STILL executes straight away (in IE). What is very weird is that a second or two later, that function will work, so it seems that the Flash is not completely loaded in FireFox? But it runs to the last line of my constructor, so I would believe it's loaded. Any idea please, I am really stuck. Thanks a lot, Rudy

  • .net real time stream processing - needed huge and fast RAM buffer

    - by mack369
    The application I'm developing communicates with an digital audio device, which is capable of sending 24 different voice streams at the same time. The device is connected via USB, using FTDI device (serial port emulator) and D2XX Drivers (basic COM driver is to slow to handle transfer of 4.5Mbit). Basically the application consist of 3 threads: Main thread - GUI, control, ect. Bus reader - in this thread data is continuously read from the device and saved to a file buffer (there is no logic in this thread) Data interpreter - this thread reads the data from file buffer, converts to samples, does simple sample processing and saves the samples to separate wav files. The reason why I used file buffer is that I wanted to be sure that I won't loose any samples. The application doesn't use recording all the time, so I've chosen this solution because it was safe. The application works fine, except that buffered wave file generator is pretty slow. For 24 parallel records of 1 minute, it takes about 4 minutes to complete the recording. I'm pretty sure that eliminating the use of hard drive in this process will increase the speed much. The second problem is that the file buffer is really heavy for long records and I can't clean this up until the end of data processing (it would slow down the process even more). For RAM buffer I need at lest 1GB to make it work properly. What is the best way to allocate such a big amount of memory in .NET? I'm going to use this memory in 2 threads so a fast synchronization mechanism needed. I'm thinking about a cycle buffer: one big array, the Bus Reader saves the data, the Data Interpreter reads it. What do you think about it? [edit] Now for buffering I'm using classes BinaryReader and BinaryWriter based on a file.

  • Comet, responseText and memory usage

    - by ithcy
    Is there a way to clear out the responseText of an XHR object without destroying the XHR object? I need to keep a persistent connection open to a web server to feed live data to a browser. The problem is, there is a relatively large amount of data coming through (several hundred K per second constantly), so memory usage is a big problem, because this connection must remain open for at least several minutes. responseText gets very big very quickly, even though the JSON I send back has been crunched as small as it can get. Due to the way the server-side app works, if I use AJAX-style short polling and just destroy the XHR object when I'm done with it, I miss significant amounts of important data even in the few milliseconds it takes to parse the response, create a new XHR and send it out. I do not have the option to use overlapping requests, as the web server only accepts one connection at a time. (Don't ask.) So Comet is exactly the model I need. What I would like to do is parse each JSON chunk as it comes back from the server, and then clear out responseText so that I can keep using the same connection. However, responseText is read-only. It cannot be directly emptied by any method I have found. Is there a part of the picture I am missing here? Does anyone know any tricks I can use to free up responseText when I'm done reading it? Or is there another place the server responses can go? I am not including code because this is really almost a code-agnostic question. The Javascript routines that spawn the XHRs and handle the returned data are very, very simple.

  • How to get DIVs into this code via JQuery

    - by ludz
    Heya everyone I been struggling along with this piece of code for the longest time, its driving me insane. I am trying many different things and looking at past posts here but nothing seems to be helping. Basicly i have a jquery pagination code in place and i want to add animated transitions between pages. With some assistance i got that working correctly however this causes the page to jump around as the new items fade in and out. To fix this i need a DIV wrapped around each selection of results. I have been trying to use .wrap .html .wrapinner .append and i cant get any of it to work properly. The 2 areas where i beleive the code needs to be place are as follows: $('#content').children().slice(0, show_per_page).css('display', 'block'); and $('#content').children().fadeOut('slow').slice(start_from, end_on).fadeIn('slow'); Full original code: http://tutsvalley.com/tutorials/making-a-jquery-pagination-system/ Only the second line of code posted here has been altered. Basicly i want to wrap each group of sliced output in a DIV. I hope that makes sense, if you need anymore information please let me know. Any ideas or suggestions on what to try it would be much apreciated as its currently driving me crazy :) Ludz~
