  • Div click and AUTOCOMPLETE password dialog problem

    - by ticky
    And what if you want to autocomplete passwords? I am using similar thing here... I am using Div (id=loginButton) and it has some image - I don't want button control in MVC application (), neither image button. I have hidden input control which is hidden button actually (id=submit_btn). So, on div's (id=loginButton) click, I want to call hidden input control (id=submit_btn) and it's submit action. HTML: <div id="loginButton" > </div> <input type="submit" style="display:none" name="submit" id="submit_btn" /> And JQuery: $(document).ready(function() { $('#loginButton').click(function() { $('#LoginForm').submit(); }); $("form[action$='HandleLoginForm']").submit(function() { Login(); return false; }); return false; }); Function Login() is working with Ajax, without downloading file dialog, but I need also auto complete passwords dialog. function Login() { var urlData = $("#LoginForm").serialize(); if (returnUrl != "") { urlData = $("#LoginForm").serialize() + "&returnUrl=" + returnUrl; } $.ajax({ url: $("#LoginForm").attr("action"), type: "POST", data: urlData, dataType: "json", success: function(result) { if (result.Content != null) { if (result.Valid) { window.location = result.Content.toString(); } else { document.body.innerHTML = result.Content.toString(); } } } }); return false; } It is easy when you use only <input type="submit"> instead of DIV. Form knows that it is for auto completing passwords, but if I use div and force hidden button click like in the code from below, it doesn't show autocomplete password dialog. $('#submit_btn').click(); It will not work. User is logged in, but no reminding for browser to store password. I need this.

  • How do I get the collection of Model State Errors in ASP.NET MVC?

    - by Ryan Montgomery
    How do I get the collection of errors in a view? I don't want to use the Html Helper Validation Summary or Validation Message. Instead I want to check for errors and if any display them in specific format. Also on the input controls I want to check for a specific property error and add a class to the input. P.S. I'm using the Spark View Engine but the idea should be the same. So I figured I could do something like... <if condition="${ModelState.Errors.Count > 0}"> DispalyErrorSummary() </if> ....and also... <input type="text" value="${Model.Name}" class="?{ModelState.Errors["Name"] != string.empty} error" /> .... Or something like that. UPDATE My final solution looked like this: <input type="text" value="${ViewData.Model.Name}" class="text error?{!ViewData.ModelState.IsValid && ViewData.ModelState["Name"].Errors.Count() > 0}" id="Name" name="Name" /> This only adds the error css class if this property has an error.

  • What is usefulness of W3C's Semantic Data Extractor in semantically correct XHTML CSS Development?

    - by metal-gear-solid
    What is the usefulness of W3C's Semantic Data Extractor? http://www.w3.org/2003/12/semantic-extractor.html This tool, geared by an XSLT stylesheet, tries to extract some information from a HTML semantic rich document. It only uses information available through a good usage of the semantics defined in HTML. The aim is to show that providing a semantically rich HTML gives much more value to your code: using a semantically rich HTML code allows a better use of CSS, makes your HTML intelligible to a wider range of user agents (especially search engines bots). As an aside, it can give clues to user agents developers on some hooks that could be interesting to add in their product. After checking validation for CSS and HTML. Should i go for Semantic Data Extractor tool. What it does. and how it can improved our coding.? Is anyone using it?

  • More efficient approach to XSLT for-each

    - by Paul
    I have an XSLT which takes a . delimted string and splits it into two fields for a SQL statement: <xsl:for-each select="tokenize(Path,'\.')"> <xsl:choose> <xsl:when test="position() = 1 and position() = last()">SITE = '<xsl:value-of select="."/>' AND PATH = ''</xsl:when> <xsl:when test="position() = 1 and position() != last()">SITE = '<xsl:value-of select="."/>' </xsl:when> <xsl:when test="position() = 2 and position() = last()">AND PATH = '<xsl:value-of select="."/>' </xsl:when> <xsl:when test="position() = 2">AND PATH = '<xsl:value-of select="."/></xsl:when> <xsl:when test="position() > 2 and position() != last()">.<xsl:value-of select="."/></xsl:when> <xsl:when test="position() > 2 and position() = last()">.<xsl:value-of select="."/>' </xsl:when> <xsl:otherwise>zxyarglfaux</xsl:otherwise> </xsl:choose> </xsl:for-each> The results are as follows: INPUT: North OUTPUT: SITE = 'North' AND PATH = '' INPUT: North.A OUTPUT: SITE = 'North' AND PATH = 'A' INPUT: North.A.B OUTPUT: SITE = 'North' AND PATH = 'A.B' INPUT: North.A.B.C OUTPUT: SITE = 'North' AND PATH = 'A.B.C' This works, but is very lengthy. Can anyone see a more efficient approach? Thanks!

  • Post method in Servlet is not being called again after being executed once

    - by SaurabhCsIITKgp
    I am implementing a database based web application using servlets. Now, when I input a parameter using a form in the jsp page, it redirects it to a servlet which subsequently adds the value to the database (the servlet creates a new table if the table doesn't already exist). The creation of the table and the addition of value works fine if the table doesn't already exists. Once it is created however and the parameter is inputted again in the form, the submit button no longer redirects it to the servlet. Nor is the value added to the database. Kindly advise me as to where I am going wrong. Following are the snippets of my code: From the JSP page (/showmanager is the urlpattern of the servlet): <form action="showmanager" method="post"> <h3>Enter name of the show: </h3> <input type="text" name="showname" value=""> <input type="hidden" name="task" value="addshow" /> <input type="button" value="Add Show"> </form> From the servlet (POST method): p rotected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { if(request.getParameter("task").equals("addshow")){ this.addShow(request.getParameter("showname")); response.sendRedirect("showmanager.jsp"); } } Method to add in database: protected boolean addShow(String showname){ try{ statement =con.prepareStatement("INSERT INTO showdb10(name) VALUES ('"+showname+"')"); if(statement.executeUpdate()>0){ return true; } } catch(Exception e) { try{ statement =con.prepareStatement("create table showdb10 (id int NOT NULL AUTO_INCREMENT, name varchar(255) NOT NULL, date varchar(20),time varchar(20), b_total int, o_total int, b_avbl int, o_avbl int, b_price double(10,2), o_price double(10,2), seat_no varchar(20), transaction_id varchar(255), total_sales double(10,2), paymnt_artists double(10,2), paymnt_othr double(10,2), flag varchar(20), PRIMARY KEY(id))"); statement.executeUpdate(); statement =con.prepareStatement("INSERT INTO showdb10(name) VALUES ('"+showname+"')"); if(statement.executeUpdate()>0){ return true; } }catch(Exception e2){} } return false; }

  • Error returning Ajax in IE7

    - by GuiPereira
    Hi everybody! It's my first question here. First of all, sorry for my 'not perfect' english... I'm developing an ASP.NET MVC application with AJAX. I have the following code in the View: <% using(Html.BeginForm(null, "Home", FormMethod.Post, new{id="formcpf"})){ %> <p> <input name="tipo" type="radio" value="GeraCPF" /> CPF <input type="radio" name="tipo" value="GeraCNPJ" /> CNPJ </p> <p> <input type="submit" id="sbmt" value="Gerar" /> <br /><br /> <span id="lblCPF" class="respostaBG"></span> </p> <%} % and the following Javascript to call an Ajax request: $(document).ready(function() { $("form#formcpf").submit(function(event) { $(this).attr("action", $("input[@name='tipo']:checked").val()); event.preventDefault(); hijack(this, update_sessions, "html"); }); }); function hijack(form, callback, format) { $.ajax({ url: form.action, type: form.method, dataType: format, data: $(form).serialize(), success: callback }); } function update_sessions(result) { $("#lblCPF").html(result); } in Firefox and Chrome works fine, but in IE7 sometimes returns the value into the label, sometimes not. I have to keep submiting to get the return. Anyone could help?

  • C# TcpClient, getting back the entire response from a telnet device

    - by Dan Bailiff
    I'm writing a configuration tool for a device that can communicate via telnet. The tool sends a command via TcpClient.GetStream().Write(...), and then checks for the device response via TcpClient.GetStream().ReadByte(). This works fine in unit tests or when I'm stepping through code slowly. If I run the config tool such that it performs multiple commands consecutively, then the behavior of the read is inconsistent. By inconsistent I mean sometimes the data is missing, incomplete or partially garbled. So even though the device performed the operation and responded, my code to check for the response was unreliable. I "fixed" this problem by adding a Thread.Sleep to make sure the read method waits long enough for the device to complete its job and send back the whole response (in this case 1.5 seconds was a safe amount). I feel like this is wrong, blocking everything for a fixed time, and I wonder if there is a better way to get the read method to wait only long enough to get the whole response from the device. private string Read() { if (!tcpClient.Connected) throw (new Exception("Read() failed: Telnet connection not available.")); StringBuilder sb = new StringBuilder(); do { ParseTelnet(ref sb); System.Threading.Thread.Sleep(1500); } while (tcpClient.Available > 0); return sb.ToString(); } private void ParseTelnet(ref StringBuilder sb) { while (tcpClient.Available > 0) { int input = tcpClient.GetStream().ReadByte(); switch (input) { // parse the input // ... do other things in special cases default: sb.Append((char)input); break; } } }

  • Dynamically generated PDF files working in most readers except Adobe Reader

    - by Shane
    I'm trying to dynamically generate PDFs from user input, where I basically print the user input and overlay it on an existing PDF that I did not create. It works, with one major exception. Adobe Reader doesn't read it properly, on Windows or on Linux. QuickOffice on my phone doesn't read it either. So I thought I'd trace the path of me creating the files - 1 - Original PDF of background PDF 1.2 made with Adobe Distiller with the LZW encoding. I didn't make this. 2 - PDF of background PDF 1.4 made with Ghostscript. I used pdf2ps then ps2pdf on the above to strip LZW so that the reportlab and pyPDF libraries would recognize it. Note that this file looks "fuzzy," like a bad scan, in Adobe Reader, but looks fine in other readers. 3 - PDF of user-input text formatted to be combined with background PDF 1.3 made with Reportlab from user input. Opens properly and looks good in every reader I've tried. 4 - Finished PDF PDF 1.3 made from PyPDF's mergePage() function on 2 and 3. Does not open in: Adobe Reader for Windows Adobe Reader for Linux QuickOffice for Android Opens perfectly in: Google Docs' PDF viewer on the web evince for linux ghostscript viewer for linux Foxit reader for Windows Preview for Mac Are there known issues that I should know about? I don't know exactly what "flate" is, but from the internet I gather that it's some sort of open source alternative to LZW for PDF compression? Could that be causing my problem? If so, are there any libraries I could use to fix the cause in my code?

  • generating images with php based on css3 gradient settings?

    - by thrice801
    Hi, Does anyone know if there is a php library, or if there isnt, have any input on how one would go about generating an image via php, from basic HTML element input settings, and CSS 3 gradient parameters. To give an example on why this would be useful, I have found as of a couple days ago, that laying out the wireframe for a webpage using basic Css3 gradient styling speeds up my design and development time by, well, alot. I cant design from photoshop, Ill spend hours tweaking stupid little things that only lead to me tweaking more stupid little things to compensate for stupid little changes. -- So, I had an epiphany to stop using photoshop until the end, and just focus on the main styling of elements, text-shadow, and borders for highlights, and I feel I am able to make super clean, more focused layout by being more restricted to the basics of graphic design with just css. Anyways, so Im planning on after I have the layouts done, to then recreate the graphics in photoshop, so that every browser is able to render the images. This wont take long, but as far as repeating it goes, if I could just do it with PHP, that would be incredible. For instance, take this style for example, which renders a clean looking ipad/pod ish menu/button gradient. [code] background: -moz-linear-gradient(top, #808080, #454545 50%, #313131 51%, #333333); background: -webkit-gradient(linear, left top, left bottom, color-stop(0, #808080), color-stop(.5, #454545), color-stop(.5, #313131), to(#333333));[/code] Basically what Im looking to do is take one or more inputs that control rendering the image as you see there. Take a width and a height input, and then render the image gradient accordingly, so I can save it, upload it and then use it in my designs. So ya, I know PHP has some image generation capabilities but I dont know to what extent, any input on the most effective way to go about doing this or whether it already exists, would be appreciated!

  • Java: Efficiency of the readLine method of the BufferedReader and possible alternatives

    - by Luhar
    We are working to reduce the latency and increase the performance of a process written in Java that consumes data (xml strings) from a socket via the readLine() method of the BufferedReader class. The data is delimited by the end of line separater (\n), and each line can be of a variable length (6KBits - 32KBits). Our code looks like: Socket sock = connection; InputStream in = sock.getInputStream(); BufferedReader inputReader = new BufferedReader(new InputStreamReader(in)); ... do { String input = inputReader.readLine(); // Executor call to parse the input thread in a seperate thread }while(true) So I have a couple of questions: Will the inputReader.readLine() method return as soon as it hits the \n character or will it wait till the buffer is full? Is there a faster of picking up data from the socket than using a BufferedReader? What happens when the size of the input string is smaller than the size of the Socket's receive buffer? What happens when the size of the input string is bigger than the size of the Socket's receive buffer? I am getting to grips (slowly) with Java's IO libraries, so any pointers are much appreciated. Thank you!

  • Java: Infinite loop using Scanner in.hasNextInt()

    - by Tomek
    Hi everyone, I am using the following code: while (invalidInput) { // ask the user to specify a number to update the times by System.out.print("Specify an integer between 0 and 5: "); if (in.hasNextInt()) { // get the update value updateValue = in.nextInt(); // check to see if it was within range if (updateValue >= 0 && updateValue <= 5) { invalidInput = false; } else { System.out.println("You have not entered a number between 0 and 5. Try again."); } } else { System.out.println("You have entered an invalid input. Try again."); } } However, if I enter a 'w' it will tell me "You have entered invalid input. Try Again." and then it will go into an infinite loop showing the text "Specify an integer between 0 and 5: You have entered an invalid input. Try again." Why is this happening? Isn't the program supposed to wait for the user to input and press enter each time it reaches the statement: if (in.hasNextInt()) Thanks in advance, Tomek

  • DVD playback with Windows Media Player 11 works fine, but when copied to HDD and then played back, t

    - by stakx
    I have several DVDs with short documentaries on it. Since the notebook I'm using (a Dell Latitude E6400) has only one DVD drive, and I might play back those short movies very often, I thought of copying them to the HDD and playing them back from there. However, I've run into a problem, namely stuttering audio. Problem description: When I play back these movies directly from DVD (with Windows Media Player 11 under Windows Vista), everything works fine. Smooth video, no significant audio problems (only the occasional click). But as soon as I copy any of these DVDs to the HDD and try to play them back from there (e.g. using the wmpdvd://drive/title/chapter?contentdir=path protocol, I get stuttering audio — audio playback sounds like a machine gun for a third of a second or so, approx. every 8 seconds. I have tried converting the VOB files from the DVD to another format (ie. ripping), but that resulted in a noticeable downgrade of picture quality. Therefore I thought it best to keep the files in their original format, if possible. Still, I suspect that the stuttering audio is due to some (de-)muxing problem, and that changing the file format might help. (After all, video playback is fine; therefore I don't think that the hardware is too slow for playback.) Only thing is, I don't know how to convert the VOB files to another Windows Media Player-compatible format without quality loss. I hope someone can help me, or give me further pointers on things I could try out to get HDD playback to work without the problem described. Some things I've tried so far, without any success: VOB2MPG, in order to convert the .vob file to a .mpg file. But that changes only the A/V container, not the content. No re-encoding takes place at all. Re-encoding with MPlayer/MEncoder. Lots of quality loss there, and I frankly haven't got the time to test all possible settings combinations available. Disabling all plug-ins, equalizers, etc. in Windows Media Player. Disabling all hardware acceleration on the audio playback device. Further info on the VOB files I'm trying to playback: The video format is MPEG ES, PAL 720x576 pixels @ 24/25 frames per second. The sound stream is uncompressed PCM, 16-bit stereo @ 48kHz. (Might it help if I somehow re-encoded the sound stream at a lower resolution, or as an MP3? If so, how would I do this without changing the video stream?) P.S.: I am limited to using Windows Media Player (11). (I previously tried MPlayer btw., but the video playback quality was surprisingly bad.)

  • Java hangs when trying to close a ProcessBuilder OutputStream

    - by Jeff Bullard
    I have the following Java code to start a ProcessBuilder, open an OutputStream, have the process write a string to an OutputStream, and then close the OutputStream. The whole thing hangs indefinitely when I try to close the OutputStream. This only happens on Windows, never on Mac or Linux. Some of the related questions seem to be close to the same problem I'm having, but I haven't been able to figure out how to apply the answers to my problem, as I am a relative newbie with Java. Here is the code. You can see I have put in a lot of println statements to try to isolate the problem. System.out.println("GenMic trying to get the input file now"); System.out.flush(); OutputStream out = child.getOutputStream(); try { System.out.println("GenMic getting ready to write the input file to out"); System.out.flush(); out.write(intext.getBytes()); System.out.println("GenMic finished writing to out"); System.out.flush(); out.close(); System.out.println("GenMic closed OutputStream"); System.out.flush(); } catch (IOException iox) { System.out.println("GenMic caught IOException 2"); System.out.flush(); String detailedMessage = iox.getMessage(); System.out.println("Exception: " + detailedMessage); System.out.flush(); throw new RuntimeException(iox); } And here is the output when this chunk is executed: GenMic trying to get the input file now GenMic getting ready to write the input file to out GenMic finished writing to out

  • Code Golf: Rotating Maze

    - by trinithis
    Code Golf: Rotating Maze Make a program that takes in a file consisting of a maze. The maze has walls given by '#'. The maze must include a single ball, given by a 'o' and any number of holes given by a '@'. The maze file can either be entered via command line or read in as a line through standard input. Please specify which in your solution. Your program then does the following: 1: If the ball is not directly above a wall, drop it down to the nearest wall. 2: If the ball passes through a hole during step 1, remove the ball. 3: Display the maze. 4: If there is no ball in the maze, exit. 5: Read a line from the standard input. Given a 1, rotate the maze counterclockwise. Given a 2, rotate the maze clockwise. Rotations are done by 90 degrees. It is up to you to decide if extraneous whitespace is allowed. If the user enters other inputs, repeat this step. 6: Goto step 1. You may assume all input mazes are closed. Note, a hole effectively acts as a wall in this regard. You may assume all input mazes have no extraneous whitespace. The shortest source code by character count wins. Example mazes: ###### #o @# ###### ########### #o # # ####### # ###@ # ######### ########################### # # # # @ # # # # ## # # ####o#### # # # # # # ######### # @ ######################

  • split line of text

    - by plys
    Hi all, I was wondering if there is an algorithm to split a line into multiple lines, so that the resulting set of multiple lines fit into a square shape rather than a rectangle. Let me give some examples, Input: Hi this is a really long line. Output: Hi this is a really long line Input: a b c d e f Output: a b c d e f Input: This is really such looooooooooooooooooooong line.This is the end. Output: This is really such looooooooooooooooooooong line This is the end. If you see in the above examples, input line fits into a wide rectangle. But the output more or less fits into a square shape. Essentially what needs to be done here is simply count the number of characters in the line, take the square root of that number. Then put square root number of characters in each line. But in the above example, the splitting needs to be done by respecting word wraps instead of characters. Is there any standard algorithm for this? Any code examples/ pointers would be appreciated!

  • I need to get form data from multiple forms on one page using $_POST

    - by CDeanMartin
    My project is a menu that displays daily specials at a cafe. The Pointy Haired Boss(PHB) needs to add/remove items from the menu on a daily basis, so I stored all dishes with MySQL, and created a page which will load all menu items as buttons. When clicked, the button will UPDATE the item, turning it on or off. I need form data to detect which button was pressed, so my query knows which $menuItem to UPDATE. That is the purpose of the hidden fields. <html><head></head> <body> <html><head></head> <body> <?php include("getElement.php"); $keys = array_keys($_POST); echo $keys[0]; echo $keys[1]; //if(isset($_POST["menuItem"])){ //toggleItem($_POST["menuItem"]); //echo print_r(array_keys($_POST));} ?> <form name="b" action="scratchpad.php" method="post" > <input type="hidden" name="b" value="Cajun Gumbo"/> <input type="submit" style="color:blue" value="Cajun Gumbo" /> </form> <form name="a" action="scratchpad.php" method="post" > <input type="hidden" name="a" value="Guacomole Burger"/> <input type="submit" style="color:blue" value="Guacomole Burger" /> </form> </body> </html> Can I get $_POST to identify which button was pressed?

  • When to Store Temporary Values in Hidden Field vs. Session vs. Database?

    - by viatropos
    I am trying to build a simple OpenID login panel similar to how Stack Overflow's works. The goal is: User clicks OpenID/Oauth provider OpenID/Oauth stuff happens, we end up with the result (already made that) Then we want to confirm that the user wants to actually create a new account (vs. associating account with another OpenID account). In StackOverflow, they keep a hidden field on a form that looks like this: <form action="/users/openidconfirm" method="post"> <p>This is an OpenID we haven't seen on Stack Overflow before:</p> <p class="openid-identifier">https://me.yahoo.com/a/some-hash</p> <p>Do you want to associate this OpenID with your Stack Overflow account?</p> <div> <input type="hidden" name="fkey" value="9792ab2zza1q2a4ac414casdfa137eafba7"> <input type="hidden" name="s" value="c1a3q133-11fa-49r0-a7bz-da19849383218"> <input type="submit" value="Associate OpenID"> <input type="button" value="Cancel" onclick="window.location.href = 'http://stackoverflow.com/users/169992/viatropos?s=c1a3q133-11fa-49r0-a7bz-da19849383218'"> </div> </form> Initial question is, what are those hashes fkey and s? Not that I really care what these specific hashes are, but what it seems like is happening is they have processed the openid response and saved it to the DB in a temporary object or something, and from there they generate these keys, because they don't look like Oauth keys to me. Main situation is: after I have processed OpenID/Oauth responses, I don't yet want to create a new user/account until the user submits the "confirm" form. Should I store the keys and tokens temporarily in a "Confirm" form like this? Or is there a better way? It seems that using a temp database object would be a lot of work to manage properly. Thanks for the help. Lance

  • How do I get Bison/YACC to not recognize a command until it parses the whole string?

    - by chucknelson
    I have some bison grammar: input: /* empty */ | input command ; command: builtin | external ; builtin: CD { printf("Changing to home directory...\n"); } | CD WORD printf("Changing to directroy %s\n", $2); } ; I'm wondering how I get Bison to not accept (YYACCEPT?) something as a command until it reads ALL of the input. So I can have all these rules below that use recursion or whatever to build things up, which either results in a valid command or something that's not going to work. One simple test I'm doing with the code above is just entering "cd mydir mydir". Bison parses CD and WORD and goes "hey! this is a command, put it to the top!". Then the next token it finds is just WORD, which has no rule, and then it reports an error. I want it to read the whole line and realize CD WORD WORD is not a rule, and then report an error. I think I'm missing something obvious and would greatly appreciate any help - thanks! Also - I've tried using input command NEWLINE or something similar, but it still pushes CD WORD to the top as a command and then parses the extra WORD separately.

  • Switching from form_for to remote_form_for problems with submit changes in Rails

    - by Matthias Günther
    Hi there, another day with Rails and today I want to use Ajax. linkt_remote_link for changing a text was pretty easy so I thought it would also be easy to switch my form_for loop just to an ajax request form with remote_form_for, but the problem with the remote_form_for is that it doesn't save my changes? Here the code that worked: <% form_for bill, :url => {:action => 'update', :id => bill.id} do |f| %> # make the processing e.g. displaying texfields and so on <%= submit_tag 'speichern'%> It produces the following html code: <form action="/adminbill/update/58" class="edit_bill" id="edit_bill_58" method="post"><div style="margin:0;padding:0;display:inline"><input name="_method" type="hidden" value="put" /></div> <!-- here the html things for the forms --> <input class="button" name="commit" type="submit" value="speichern" /> Here the code which don't save me the changes and submit them: <% remote_form_for bill, :url => {:action => 'update', :id => bill.id} do |f| %> # make the processing e.g. displaying texfields and so on <%= submit_tag 'speichern'%> It produces the following html code: <form action="/adminbill/update/58" class="edit_bill" id="edit_bill_58" method="post" onsubmit="$.ajax({data:$.param($(this).serializeArray()), dataType:'script', type:'post', url:'/adminbill/update/58'}); return false;"><div style="margin:0;padding:0;display:inline"><input name="_method" type="hidden" value="put" /></div> <!-- here the html things for the forms --> <input class="button" name="commit" type="submit" value="speichern" /> I don't know if I have to consider something special when using remote_form_for (see remote_form_for)
