  • Problems with multi-line comments jquery

    - by c0mrade
    Hello, I'm making a image website with a bunch of images on the website, and below every image there is possibility of commenting the image and after that comments gets displayed without page loading and the comment content, the problem is when I have long comments which break the current line they don't get displayed since my comment box css overflow is hidden. Here is example : This is a comment - This is displayed properly This is a comment This is a comment This is a comment - this is not displayed properly since it break line. Here is the jQuery code for this : $.ajax({ type: "POST", url: "<?=base_url()?>imagesform/post_comment", data: datas, success: function () { $("#image-comments-" + image_id).attr("class", "comments"); $("#image-comments-" + image_id).append("<li id=\"new_append_" + image_id+ "\">" + $("#image").find(".comment").val() + "</li>").children(':last').height($('.comments li:last').height()).hide().slideDown(500, function () { var bodyHeight = $('html').height(); $('.addComment').fadeOut(300, function () { $('html').height(bodyHeight); }); }); alert($("#image").find(".comment").val()); } }); Here the $("#image").find(".comment").val() is the value of the text-area in which comment is inputted, when I alert it the whole multi line input is there put its not being appended to the li properly, that is part when I get confused, any suggestions why only part of the inputted string is appended?

  • Jquery ajax ($.ajax) not working on chrome. please help

    - by racky
    Hi, I need a little help to figure out why the following code does not work on google chrome 5/windows xp. It works well on all other browsers (IE, FF, Safri, Opera etc). Can someone shed some light around this? /* AJAX Request */ jq("#a-post-request").unbind("click").bind("click", function(e){ //jq("#loading").css({"display":"block"}); jq.ajax({ url: "search_data_table.html", type: "get", cache: false, error: function(){alert ("No data found for your search.");}, success: function(data){ jq("#search-results-table tbody").empty().append(data); jq("#search-results").css({"display":"block"}); jq("#search-results-table").trigger("update"); // this one is for the table sorter plugin // set sorting column and direction, this will sort on the first column. var sorting = [[0,0]];// this one is for the table sorter plugin // sort on the first column . jq("#search-results-table").trigger("sorton",[sorting]);// this one is for the table sorter plugin e.preventDefault(); } }); }); Many thanks, Racky

  • iMX31 dependencies?

    - by Abhi
    Dear all I am beginner in an silverlight application. So at first i looked on demo application which is provided by wince 6.0 r3 at location WINCE600\PUBLIC\COMMON\OAK\DEMOS\XAMLPERF - this contains c++ code and WINCE600\PUBLIC\COMMON\OAK\FILES\XAMLPERF - this contains xaml file with the images Now before running this application in an emulator. I at first proceeded with the following: I have first taken my workspace went to catalog item and added "Silverlight for Windows Embedded" from the drop down menu of an catalog item Then right clicked on solution explorer and choosed on properties and under configuration in drop down menu i have selected environment variables where i have added new variable called "sysgen_samplexamlperf" and assigned value as 1 for that variable. Now after rebuiding the application, i have dumped the image into emulator and i found that at desktop of device emulator i can see the exe file to which i run and i can see the application is working fine with 3d effects. Now same thing i proceeded in iMX31 hardware and i was not able to see the application running in a proper manner as it was performing in an emulator. So now what i feel is that there be any dependency when we run the application on hardware. So what can be the dependency? Also in this location "WINCE600\PUBLIC\COMMON\OAK\FILES\XAMLPERF" the images are in png format. So is there any dependency with an image format? Thanks and regards

  • How to make buttons in python/pygame?

    - by user1334014
    I'm making a game in pygame and on the first screen I want there to be buttons that you can press to (i) start the game, (ii) load a new screen with instructions, and (iii) exit the program. I've found this code online for button making, but I don't really understand it (I'm not that good at object oriented programming). If I could get some explanation as to what it's doing that would be great. Also, when I use it and try to open a file on my computer using the file path, I get the error sh: filepath :Permission denied, which I don't know how to solve. #load_image is used in most pygame programs for loading images def load_image(name, colorkey=None): fullname = os.path.join('data', name) try: image = pygame.image.load(fullname) except pygame.error, message: print 'Cannot load image:', fullname raise SystemExit, message image = image.convert() if colorkey is not None: if colorkey is -1: colorkey = image.get_at((0,0)) image.set_colorkey(colorkey, RLEACCEL) return image, image.get_rect() class Button(pygame.sprite.Sprite): """Class used to create a button, use setCords to set position of topleft corner.

  • Anyone Experiencing Slow Builds With VS2010?

    - by MrKWatkins
    Hi, We've recently upgraded to the final release of VS2010 and are experiencing very slow build times compared to the same code under 2008. I was wondering if anyone else is experiencing the same so I can work out whether it's just our environment or not? A few details: Using VS2010 Ultimate on Windows 7 with fairly beefy machines, talking to TFS 2010. The solution has been upgraded from VS2008 but still builds against .NET 3.5 and ASP.NET MVC 1.0. It doesn't seem to be the compilation itself taking long but something else in the build process. This is because even projects that are up to date and don't need compiling are taking a few seconds or so to process. It's not due to an Visual Studio addin because a couple guys in the team haven't installed any. The first build after loading VS2010 is pretty quick, then they seem to slow down over time. For example on of the projects in my solution just took 00:00:00.08 to process after a restart. (The project was up to date and didn't need compiling) I then immediately hit rebuild and it jumps to 00:00:01.33. We're also experiencing the problem with another solution that uses .NET 4.0 that was building perfectly fine under VS2010 RC. There are no build events or anything like that I can blame, just straightforward assembly builds. The IDE is not very responsive during the slow builds. Anyone else has similar problems? Update: It looks like the resolving assembly references is taking a long time. Looking at the MSBuild diagnostic output or the example above the first build has 30ms for ResolveAssemblyReferences, the second build has 800ms. Subsequent builds seem to be taking longer copying stuff around, e.g. CopyFilesToOutputDirectory jumps from 1ms to 27ms.

  • Is it possible to cache all the data in a SQL Server CE database using LinqToSql?

    - by DanM
    I'm using LinqToSql to query a small, simple SQL Server CE database. I've noticed that any operations involving sub-properties are disappointingly slow. For example, if I have a Customer table that is referenced by an Order table, LinqToSql will automatically create an EntitySet<Order> property. This is a nice convenience, allowing me to do things like Customer.Order.Where(o => o.ProductName = "Stopwatch"), but for some reason, SQL Server CE hangs up pretty bad when I try to do stuff like this. One of my queries, which isn't really that complicated takes 3-4 seconds to complete. I can get the speed up to acceptable, even fast, if I just grab the two tables individually and convert them to List<Customer> and List<Order>, then join then manually with my own query, but this is throwing out a lot of what makes LinqToSql so appealing. So, I'm wondering if I can somehow get the whole database into RAM and just query that way, then occasionally save it. Is this possible? How? If not, is there anything else I can do to boost the performance besides resorting to doing all the joins manually? Note: My database in its initial state is about 250K and I don't expect it to grow to more than 1-2Mb. So, loading the data into RAM certainly wouldn't be a problem from a memory point of view. Update Here are the table definitions for the example I used in my question: create table Order ( Id int identity(1, 1) primary key, ProductName ntext null ) create table Customer ( Id int identity(1, 1) primary key, OrderId int null references Order (Id) )

  • jQuery adding a function to a link question

    - by wali
    Hello all, I have a dynamically created table which in the last <td> there is a hidden <div> which is shown when the user hovers over a link in the <td>. That all works fine but there are several links in the div that I want to fire a function based on the id of the link concat'd with an string captured from a <td> from the parent row. I can capture the the variables I need from the id and <td> but something is wrong with the click function I have created. I monitored the function in FireBug and the function appears to be firing on all of the links instead of the one that is clicked. Here is my working code: function fixLink() { $('a.batchMatchLink').click( function() { var r = $(this).parent().parent().parent().parent().parent(); var x = $(this).attr("id"); var a = $(r).find('td:nth-child(6)').text(); var st = x + "." + a; fireLink(st); } ); } function fireLink(st) { $.ajax({ type: "POST", url: "AjaxWcf.svc/MatchBatch", contentType: "application/json; charset=utf-8", data: st, dataType: "json", success: function(msg) { alert("Entry has been updated"); }, error: AjaxFailed }); Why are all of the links firing? Thanks!!!

  • JavaScript Fails to load content correctly on start

    - by Gaz_Edge
    I have inherited an image gallery constructed using javascript. I believe it uses a variation of JQuery, but it seems to have been heavily edited. The gallery loads the first image on page load. Each image has comments below them. There are forward and backward arrows that move between images. The problem I seem to have is that if there is a comment on image one, it is not loaded on page start, the only way to get it to display is to click forward to the next image, then click back to image one. The comment is then shown. All the comments are loaded into a script in the header under var sent_comments = [{COMMENTS}] The comment HTML code on loading is as follows; <div id="comments_container"> <div id="comments"> </div> </div> Once I have clicked to image two and then back to image one, the code is; <div id="comments_container"> <div id="comments"> SOME COMMENT </div> </div> Previous image button is: <a class="prev save_state" href="#"> <img src="/next.png?" alt="Next"> </a> Im new to javascript so not really sure what I will need to do to ensure the comment is loaded for the first image when the page loads. Code here: http://static.albumexposure.net/assets/presentation-9f47b054d96f9ec2459e89619a5fe9b4.js http://static.albumexposure.net/assets/presentations/book-699d82a2beb39df264e54c5d2578e0e4.js

  • Another php array looping question

    - by Dan
    Been battling with this one for what seems, like forever. I have an array: $url_array It contains this info: Array ( [ppp] => Array ( [0] => stdClass Object ( [id] => 46660 [entity_id] => 0 [redirect_url] => http://www.google.com [type] => Image ) [1] => stdClass Object ( [id] => 52662 [entity_id] => 0 [pixel_redirect_url] => http://www.yahoo.com [type] => Image ) [2] => stdClass Object ( [id] => 53877 [entity_id] => 0 [redirect_url] => http://www.msn.com [pixel_type] => Image ) ) [total_count] => 3 ) I need to loop through it, and do things to each variable. I can get this to work: foreach ($piggies_array as $key => $value) { $id = $value[0]->id; $redirect_url = $value[0]->redirect_url; } Not unsurprisingly, it's only echoing the first value of those variables, but no matter what I try I cannot get it to loop through: $value->redirect_url; $value=>redirect_url; I would appreciate any help.

  • game currency convert: math efficient

    - by Comradsky
    For variables:4 text views named diamondText, goldText, silverText, and bronzeText;money variable unsigned int money;and an NSTimer, every .1 sec,runs function: -(void)updateMoney{ money++; bronzeText.text = [NSString stringWithFormat:@"%d",money]; silverText.text = [NSString stringWithFormat:@"%d",money%10]; goldText.text = [NSString stringWithFormat:@"%d",money%100]; diamondText.text= [NSString stringWithFormat:@"%d",money%1000]; } Given that my currency is diamond = 10 gold = 10 silver = 10 bronze = 1; What would be most efficient way to calculate and display the money labels? How would you store this variable, with GameCenter and NSDictionary or GameCenter and something else? More details are below if you don't understand. To clarify: bronze has the last 2 numbers, silver has the next 2 numbers, and so on. I understand I could use 4 ints or an array, but i would rather try to use this method, unless theres a much more efficient way. Example: When money = 1000;bronzeText = nothing, silverText = 10,goldText = nothing, diamondText = nothing; What other ways would you do this that you think would be more efficient? I will be calling a function (void)collisionDetector that detects if my player.frame crosses with a flyingObject.frame, and if that object is a coin it gives an added value to money and then calls (void)updateMoney. Im just using the timer to test this and spawn these flying objects.

  • Where to start to create an HTML website with 2 tables read from csv files using anything but php

    - by CodingIsAwesome
    I want to design a website which displays on loading two tables each with it's respective data from a csv file. Then every minute the website automatically refreshes. This problem seems so simple! But yet the solution eludes me. All of the files will be contained in 1 directory, not on a server but on a local machine. Such as sitting on the desktop. I understand if I use javascript I have to use ADO, and I'm still trying to work out how to use ASP. I am new with both languages. So far the only restriction is that I can't use PHP. So the jist so far as I can think right now is: 1. read the file 2. place the file into an array by splitting at the commas 3. write the array into td's ????? 4. then print all this out into a div ???? I have googled my heart out and can't seem to find what I'm looking for. or even piece together what I'm looking for. Everything with javascript and ADO's leads me to dead ends, I can't find anything on ASP that is helpful. Could someone please write up some sample code for a resource? Or have a better solution?

  • Form.Show() is not showing it's child controls

    - by Refracted Paladin
    I have a form, frmPleaseWait, that has a MarqueeProgressBar and a Label that I want to use when the UI is loading the data in a poorly structured app we have. The problem is that frmPleaseWait.Show() shows the form but not the controls in it. It is just a white rectangle. Now frmPleaseWait.ShowDialog() shows the child controls but doesn't let the UI load it's data. What am I missing? Below is a code snippet from where I am trying this. PleaseWait = new frmPleaseWait(); PleaseWait.Show(this); // Set all available HUD values in HUD Object HUD.LastName = GetCurrentRowVal("LastName").Trim(); HUD.FirstName = GetCurrentRowVal("FirstName").Trim(); HUD.PersonId = Convert.ToInt32(GetCurrentRowVal("PersonID").Trim()); HUD.SSn = GetCurrentRowVal("SSN").Trim(); HUD.MiddleName = GetCurrentRowVal("MiddleName").Trim(); HUD.MasterID = ConnectBLL.BLL.DriInterface.CheckForDriId(HUD.PersonId).ToString(); // This loads numerous UserControls with data shellForm.FormPaint(HUD.PersonId); PleaseWait.Close();

  • C++ and Dependency Injection in unit testing

    - by lhumongous
    Suppose I have a C++ class like so: class A { public: A() { } void SetNewB( const B& _b ) { m_B = _b; } private: B m_B; } In order to unit test something like this, I would have to break A's dependency on B. Since class A holds onto an actual object and not a pointer, I would have to refactor this code to take a pointer. Additionally, I would need to create a parent interface class for B so I can pass in my own fake of B when I test SetNewB. In this case, doesn't unit testing with dependency injection further complicate the existing code? If I make B a pointer, I'm now introducing heap allocation, and some piece of code is now responsible for cleaning it up (unless I use ref counted pointers). Additionally, if B is a rather trivial class with only a couple of member variables and functions, why introduce a whole new interface for it instead of just testing with an instance of B? I suppose you could make the argument that it would be easier to refactor A by using an interface. But are there some cases where two classes might need to be tightly coupled?

  • Java JCheckBox ArrayList help needed

    - by user2929626
    I'm new to Java and struggling with something which I'm sure must have a simple answer but I can't seem to find it. I have an array of checkbox objects defined as: ArrayList<JCheckBox> checkBoxList A JPanel is created with a grid layout and the checkboxes are added to the JPanel and the ArrayList: for (int i = 0; i < 256; i++) { JCheckBox c = new JCheckBox(); c.setSelected(false); checkBoxList.add(c); mainPanel.add(c); } Yes, there are 256 checkboxes! The panel is added to a JFrame and eventually the GUI is displayed. The user can select any combination of the 256 checkboxes. My class implements Serializable and this ArrayList of checkboxes can be saved and restored using 'Save' and 'Load' GUI buttons. My code to load the saved object is as below: public class LoadListener implements ActionListener { public void actionPerformed(ActionEvent a) { try { // Prompt the user for a load file JFileChooser fileLoad = new JFileChooser(); fileLoad.showOpenDialog(mainFrame); // Create a object/file input stream linking to the selected file ObjectInputStream is = new ObjectInputStream(new FileInputStream(fileLoad.getSelectedFile())); // Read the checkBox array list checkBoxList = (ArrayList<JCheckBox>) is.readObject(); is.close(); } catch (Exception ex) { ex.printStackTrace(); } } On loading the ArrayList object, the values of the checkboxes are correctly populated, however I want to update the checkboxes on the GUI to reflect this. Is there an easy way to do this? I assumed as the array of checkboxes had the correct values that I could just repaint the panel / frame but this doesn't work. I'd like to understand why - does my loaded array of checkbox objects no longer reflect the checkbox objects on the GUI? Any help would be much appreciated. Thanks!

  • Android designing an app to keep me logged into a wifi access point

    - by MrGibbage
    At the gym where I work out, they have an open wifi access point. The way it is set up, once you "connect", you have to navigate to a web page (it is a 1.1.X.X ip address) and click the "I agree" button, after presumably reading the user agreement. The problem is, they have it set up to log you out once an hour, which always happens in the middle of my workout. I have the SSID remembered, so it connects automatically when I come in range, but I get an android notification that further action is needed to fully connect. What I was wondering is if there a work around so that I don't have to click-through every hour? I was thinking of writing an app that could detect when I was in range, or when "half-connected", and then have it somehow complete the registration process. Perhaps this will have to be done by loading the web page in memory and then somehow clicking the "I agree" button. What I would like help with is: 1) what is the terminology involved here? What state is the connection in when I am connected, but I haven't clicked through? What other connection states may apply? If I knew that, I might just be able to research this and come up with a solution. Are these different states "detectable"? It seems like it is since I get a notification that I need to complete the registration process when I am "half-connected". 2) I know there are plugins for desktop browsers that can click buttons (like the keepass plugins, which will log you into a site). How could I replicate this in Android? Ideally I would like to do it internally, in memory, rather than firing up a browser. Possible? Comments? Is my understanding and thought process sound here, or am I overlooking something?

  • Image does not update when file name remains the same in XCode 3.1.2

    - by vman049
    Hi Everyone, I'm using XCode version 3.1.2 and am developing for iPhone using the Simulator with iOS 2.2.1 on Leopard. I had an image file named "img.jpg" in my project which I decided to switch for a different file. After adding the new file into the XCode Resources folder, I removed the first file and renamed the new file to the same name as the previous one, "img.jpg." When I run my program, however, the Simulator loads the old image instead of the new one, even though the old one has been deleted from disk (not just the reference). I tried changing the name of the file to "img2.jpg," and it worked like it should - loading the new image, but I want to keep the name "img.jpg." I ran a search with Spotlight for "img.jpg" to see if there was another copy stored somewhere that XCode was using, but it only returned my new image file. I have tried uninstalling the app from the Simulator and running the application again, but that also does not fix the problem. What must I do for XCode to recognize that I want to use the new image file and not the old one? Thanks for your help!!

  • Populate on demand a TreeView with datas in an XML

    - by m6a-uds
    Hi I have a large XML file (3000+ nodes) that I want to represent in a TreeView on ASP.NET. I cannot databind it to a XMLDataSource because loading the TreeView will then be way too slow (I never even waited long enough to see it finish...) So the solution for this would be to use the PopulateOnDemand property of the TreeNodes to load data only when needed. Problem is, I can't think of a way to acheive this... How can-I, based on the ID of a node, search a XMLDocument to get all the childnodes of the node having this ID? XML would look like that: <document ID=1> <document ID=2> <document ID=3> </document> </document> <document ID=4> </document> </document> There are nor rules on how much levels it can go down or anything...

  • Parallelize or vectorize all-against-all operation on a large number of matrices?

    - by reve_etrange
    I have approximately 5,000 matrices with the same number of rows and varying numbers of columns (20 x ~200). Each of these matrices must be compared against every other in a dynamic programming algorithm. In this question, I asked how to perform the comparison quickly and was given an excellent answer involving a 2D convolution. Serially, iteratively applying that method, like so list = who('data_matrix_prefix*') H = cell(numel(list),numel(list)); for i=1:numel(list) for j=1:numel(list) if i ~= j eval([ 'H{i,j} = compare(' char(list(i)) ',' char(list(j)) ');']); end end end is fast for small subsets of the data (e.g. for 9 matrices, 9*9 - 9 = 72 calls are made in ~1 s). However, operating on all the data requires almost 25 million calls. I have also tried using deal() to make a cell array composed entirely of the next element in data, so I could use cellfun() in a single loop: # who(), load() and struct2cell() calls place k data matrices in a 1D cell array called data. nextData = cell(k,1); for i=1:k [nextData{:}] = deal(data{i}); H{:,i} = cellfun(@compare,data,nextData,'UniformOutput',false); end Unfortunately, this is not really any faster, because all the time is in compare(). Both of these code examples seem ill-suited for parallelization. I'm having trouble figuring out how to make my variables sliced. compare() is totally vectorized; it uses matrix multiplication and conv2() exclusively (I am under the impression that all of these operations, including the cellfun(), should be multithreaded in MATLAB?). Does anyone see a (explicitly) parallelized solution or better vectorization of the problem?

  • Prolog Beginner: How to unify with arithmentic cmparison operators or how to get a set var to range

    - by sixtyfootersdude
    I am new to prolog. I need to write an integer adder that will add numbers between 0-9 to other numbers 0-9 and produce a solution 0-18. This is what I want to do: add(in1, in2, out) :- in1 < 10, in2 < 10, out < 18. I would like to be able to call it like this: To Check if it is a valid addition: ?- add(1,2,3). true ?- add(1,2,4). false With one missing variable: ?- add(X,2,3). 1 ?- add(1,4,X). 5 With multiple missing variables: ?-add(X,Y,Z). % Some output that would make sense. Some examples could be: X=1, Y=1, Z=2 ; X=2, Y=1, Z=3 ...... I realize that this is probably a pretty simplistic question and it is probably very straightforward. However cording to the prolog tutorial I am using: "Unlike unification Arithmetic Comparison Operators operators cannot be used to give values to a variable.

  • Server sends json data correctly. Client parses it wrong

    - by alois.wirkes
    I have a PHP code that generates a JSON string to send to my Android app. This part works. The problem is when my app captures that string and try to convert it into a JSONArray object. The main idea is to store that data inside a SQLite database. Here's the code that captures the JSON string: public void getPostResponse(){ try{ br = new BufferedReader(new InputStreamReader(is,"iso-8859-1"),8); sb = new StringBuilder(); line = null; while((line = br.readLine()) != null){ sb.append(line+"\n"); } is.close(); result = sb.toString(); Log.e("getPostResponse","result= "+sb.toString()); }catch(Exception e){ Log.e("log_tag","Error converting result "+e.toString()); } } And this is the result in the LogCat: 10-11 16:27:01.171: E/getPostResponse(9155): result= [{ "establecimientos":[]},{ "rutas":[]},{ "formularios":[]},{ "clientes":[]},{ "mediciones":[]}] This is why I think there's an error, the result variable should contain the whole JSON string and it doesn't. Any ideas? Variables br, sb, line and result are declared globally. JSON sent from server is already a JSONArray (starts with '[' and ends with ']'), is this what's causing the problem?

  • Binding a TextBox's Width to its parent container's ActualWidth

    - by Praetorian
    Hi, I'm loading a Textbox and a Button into a horizontal StackPanel programmatically. The size of the button (which only contains an Image) is fixed, but I can't get the textbox to fill the available width of its parent. This is what the code looks like: StackPanel parent = new StackPanel() { Orientation = Orientation.Horizontal, HorizontalAlignment = HorizontalAlignment.Stretch, VerticalAlignment = VerticalAlignment.Top, }; TextBox textbox = new TextBox() { HorizontalAlignment = HorizontalAlignment.Stretch, VerticalAlignment = VerticalAlignment.Top, //MinWidth = 375, }; Button btn = new Button() { Content = new Image() { MaxHeight = 40, MaxWidth = 40, MinHeight = 40, MinWidth = 40, Margin = new Thickness( 0 ), Source = new BitmapImage( new Uri( "btnimage.png", UriKind.Relative ) ), }, HorizontalAlignment = HorizontalAlignment.Right, BorderBrush = new SolidColorBrush( Colors.Transparent ), Margin = new Thickness( 0 ), }; btn.Click += ( ( s, e ) => OnBtnClicked( s, e, textbox ) ); parent.Children.Add( textbox ); parent.Children.Add( btn ); If I uncomment the MinWidth setting for the textbox it is displayed as I want it to, but I'd like to not have to specify a width explicitly. I tried adding a binding as follows but that doesn't work at all (the textbox just disappears!) Binding widthBinding = new Binding() { Source = parent.ActualWidth, }; passwdBox.SetBinding( TextBox.WidthProperty, widthBinding ); Thanks for your help in advance!

  • Getting information from servlet created html

    - by user541597
    I have a servlet that creates an html text box and then redirects to another servlet on submit. How can I access the value of the html text box from the new servlet? I am able to access servlet variables from the new servlet but I am not aware of how to access the value of the html generated code. thanks, Here is the servlet that gets the text input public class ServletB extends HttpServlet { public void doGet(HttpServletRequest request, HttpServletResponse response) throws IOException, ServletException { response.setContentType("text/html"); String value = System.getProperty("card"); PrintWriter out = response.getWriter(); out.println("<center><h1>Your preffered method of payment is "+value+"</h1><br />"); out.println("Please Enter Card Number<input type =\"text\" name = \"number\"/><form action=\"http://codd.cs.gsu.edu:9999/cpereyra183/servlet/ServletC\"><input type =\"submit\" value=\"Continue\" /><input type=\"button\" value=\"Cancel\" /></center>"); } }} This is the servlet the first servlet redirects to all I do is try to do is output the text input public class ServletC extends HttpServlet { public void doGet(HttpServletRequest request, HttpServletResponse response) throws IOException, ServletException { response.setContentType("text/html"); String value = System.getProperty("card"); PrintWriter out = response.getWriter(); out.println(request.getParameter("number")); } }

  • Unknown ListView Behavior

    - by st0le
    I'm currently making a SMS Application in Android, the following is a code snippet from Inbox Listactivity, I have requested a cursor from the contentresolver and used a custom adapter to add custom views into the list. Now, in the custom view i've got 2 TextViews (tvFullBody,*tvBody*)... tvFullBody contains the Full SMS Text while tvBody contains a short preview (35 characters) The tvFullBody Visibility is by default set to GONE. My idea is, when the user clicks on a list item, the tvBody should dissappear(GONE) and the tvFullBody should become visible (VISIBLE). On Clicking again, it should revert back to its original state. //isExpanded is a BitSet of the size = no of list items...keeps track of which items are expanded and which are not @Override protected void onListItemClick(ListView l, View v, int position, long id) { if(isExpanded.get(position)) { v.findViewById(R.id.tvFullBody).setVisibility(View.GONE); v.findViewById(R.id.tvBody).setVisibility(View.VISIBLE); }else { v.findViewById(R.id.tvFullBody).setVisibility(View.VISIBLE); v.findViewById(R.id.tvBody).setVisibility(View.GONE); } isExpanded.flip(position); super.onListItemClick(l, v, position, id); } The Code works as it is supposed to :) except for an undesired sideeffect.... Every 10th (or so) List Item also gets "toggled". eg. If i Expand the 1st, then the 11th, 21th list items are also expanded...Although they remain off screen, but on scrolling you get to see the undesired "expansion". By my novice analysis, i'm guessing Listview keeps track of 10 list items that are currently visible, upon scrolling, it "reuses" those same variables, which is causing this problem...(i didn't check the android source code yet.) I'd be gratefull for any suggestion, on how i should tackle this! :) I'm open to alternative methods aswell....Thanks in advance! :)
