  • jQuery ui checkboxes drive me crazy

    - by Luca Belluco
    Hello, I'm using a form with checkboxes from jQuery UI and I'm having some problems with them : here is my code : php <input type="checkbox" id="check'. $empl->getAttr('id') .'" class="intervenants" /><label for="check'. $empl->getAttr('id') .'">'.$empl->getAttr('nom').'</label>'; javascript $('.intervenants').each(function() { $(this).attr('checked',false); }); for(i = 0; i < data.list_empl.length; i++) { $('#check'+data.list_empl[i].id).attr('checked',true); } I want, as you can see, uncheck all the checkboxes, then I look in my array and try to check only the checkboxes existing in my array. The problem is that it doesn't work... I don't know what doesn't work, I've tried to put alert, to look in html but it looks like it's totall incoherent. I would really appreciate your help, thanks in advance, Luca.

  • help with Firefox extension

    - by Johnny Grass
    I'm writing a Firefox extension that creates a socket server which will output the active tab's URL when a client makes a connection to it. I have the following code in my javascript file: var serverSocket; function startServer() { var listener = { onSocketAccepted : function(socket, transport) { try { var outputString = gBrowser.currentURI.spec + "\n"; var stream = transport.openOutputStream(0,0,0); stream.write(outputString,outputString.length); stream.close(); } catch(ex2){ dump("::"+ex2); } }, onStopListening : function(socket, status){} }; try { serverSocket = Components.classes["@mozilla.org/network/server-socket;1"] .createInstance(Components.interfaces.nsIServerSocket); serverSocket.init(7055,true,-1); serverSocket.asyncListen(listener); } catch(ex){ dump(ex); } document.getElementById("status").value = "Started"; } startServer(); As it is, it works for multiple tabs in a single window. If I open multiple windows, it ignores the additional windows. I think it is creating a server socket for each window, but since they are using the same port, the additional sockets fail to initialize. I need it to create a server socket when the browser launches and continue running when I close the windows (Mac OS X). As it is, when I close a window but Firefox remains running, the socket closes and I have to restart firefox to get it up an running. How do I go about that?

  • convert password encryption from java to php

    - by Obay
    I'm trying to create a PHP version of an existing JSP program, however I'm stuck at the password encryption part. Could you please tell me how to convert this one? I know it tries to get the md5() but after that, I don't get it. I get lost in the Stringbuffer and for() parts. Can you help me out? public static String encryptPassword( String password ) { String encrypted = ""; try { MessageDigest digest = MessageDigest.getInstance( "MD5" ); byte[] passwordBytes = password.getBytes( ); digest.reset( ); digest.update( passwordBytes ); byte[] message = digest.digest( ); StringBuffer hexString = new StringBuffer(); for ( int i=0; i < message.length; i++) { hexString.append( Integer.toHexString( 0xFF & message[ i ] ) ); } encrypted = hexString.toString(); } catch( Exception e ) { } return encrypted; }

  • My images aren't updating immediately upon changing their src in javascript

    - by Dale
    I'm using the function below to change the img src. It's an array of ten images. When going through the loop, using break points, the images don't all update on the page immediately. Some of them do. If I inspect the unchanged images on the page (while paused at a breakpoint), the src has changed, but the image hasn't changed yet. All of the unchanged images get updated correctly when the function ends. Anyone know why they don't all get updated instantly and how I can force them to update? Also, is there a way I can hold off the updates of all of them until they're all reassigned and thus have them all update on the "simultaneously"? Here's my function. function mainFunction(){ finalSet = calculateSet(); for ( var int = 0; int < finalSet.length; int++) { var fileName = "cardImg" + (int); document.getElementById(fileName).src = "images/cards/" + finalSet[int].name + ".jpg"; } } Thanks for the help.

  • window.location.href not working in Safari when using onkeypress

    - by insanepaul
    I'm using an asp textbox and a search button. In Safari if I click the search button i get redirected to the search results page using javascript window.location.href. But strangely the same javascript will not redirect to the page if I press return in the textbox. Using the alert function I can see that window.location.href has the the correct url and the location bar at the top changes from the search page(default.aspx) to the search results url however when I click OK to the alert box the url at the top reverts back to the default.aspx page. It works on ie7/8/firefox/chrome but not safari. Here is my javascript,cs and aspx code: function submitSearchOnEnter(e) { var CodeForEnter = 13; var codeEnteredByUser; if (!e) var e = window.event; if (e.keyCode) codeEnteredByUser = e.keyCode; else if (e.which) codeEnteredByUser = e.which; if (codeEnteredByUser == CodeForEnter) RedirectToSearchPage(); } function RedirectToSearchPage() { var searchText = $get('<%=txtHeaderSearch.ClientID%>').value if (searchText.length) { window.location.href = "Search.aspx?searchString=" + searchText; } } protected void Page_Load(object sender, EventArgs e) { txtHeaderSearch.Attributes.Add("onkeypress", "submitSearchOnEnter(event)"); } <asp:Panel ID="pnlSearch" runat="server" DefaultButton="lnkSearch"> <asp:TextBox ID="txtHeaderSearch" runat="server" CssClass="searchBox"></asp:TextBox> <asp:LinkButton ID="lnkSearch" OnClientClick="RedirectToSearchPage(); return false;" CausesValidation="false" runat="server" CssClass="searchButton"> SEARCH </asp:LinkButton> </asp:Panel> I've tried return false; which doesn't allow me to enter any characters in the search box. I've spent ages online trying to find a solution. Maybe it has something to do with setTimeout or setTimeInterval but it didn't work unless i did it wrong.

  • How can I load txt file from internet into my jsf app?

    - by Elena
    Hi all! It's me again) I have another problem. I want to load file (for example - txt) from web. I tried to use the next code in my managed bean: public void run() { try { URL url = new URL(this.filename); URLConnection connection = url.openConnection(); bufferedReader = new BufferedReader(new InputStreamReader(connection.getInputStream())); if (bufferedReader == null) { return; } System.out.println("wwwwwwwwwwwwwwwwwwwww"); String str = bufferedReader.readLine(); System.out.println("qqqqqqqqqqqqqqqqqqqqqqq = " + str); while (bufferedReader.readLine() != null) { System.out.println("---- " + bufferedReader.readLine()); } } catch(MalformedURLException mue) { System.out.println("MalformedURLException in run() method"); mue.printStackTrace(); } catch(IOException ioe) { System.out.println("IOException in run() method"); ioe.printStackTrace(); } finally { try { bufferedReader.close(); } catch(IOException ioe) { System.out.println("UOException wile closing BufferedReader"); ioe.printStackTrace(); } } } public String doFileUpdate() { String str = FacesContext.getCurrentInstance().getExternalContext().getRequestServletPath(); System.out.println("111111111111111111111 str = " + str); str = "http://narod.ru/disk/20957166000/test.txt.html";//"http://localhost:8080/sfront/files/test.html"; System.out.println("222222222222222222222 str = " + str); FileUpdater fileUpdater = new FileUpdater(str); fileUpdater.run(); return null; } But the BufferedReader returns the html code of the current page, where i am trying to call managed bean's method. It's very strange thing - I have googled and none have had this problem. Maybe I do something wrong, maybe there us a simplest way to load file into web (jsf) app not using net API. Any ideas? Thanks very much for help! With best wishes)

  • jQuery Validate plugin - password check - minimum requirements - Regex

    - by QviXx
    I've got a little problem with my password-checker. There's got a registration form with some fields. I use jQuery Validate plugin to validate user-inputs. It all works except the password-validation: The password should meet some minimum requirements: minimum length: 8 - I just use 'minlength: 8' at least one lower-case character at least one digit Allowed Characters: A-Z a-z 0-9 @ * _ - . ! At the moment I use this code to validate the password: $.validator.addMethod("pwcheck", function(value, element) { return /^[A-Za-z0-9\d=!\-@._*]+$/.test(value); }); This Code works for the allowed characters but not for minimum requirements. I know that you can use for example (?=.*[a-z]) for a lower-case-requirement. But I just don't get it to work. If I add (?=.*[a-z]) the whole code doesn't work anymore. I need to know how to properly add the code to the existing one. Thank you for your answers! This is the complete code <script> $(function() { $("#regform").validate({ rules: { forename: { required: true }, surname: { required: true }, username: { required: true }, password: { required: true, pwcheck: true, minlength: 8 }, password2: { required: true, equalTo: "#password" }, mail1: { required: true, email: true }, mail2: { required: true, equalTo: "#mail1" } }, messages: { forename: { required: "Vornamen angeben" }, surname: { required: "Nachnamen angeben" }, username: { required: "Usernamen angeben" }, password: { required: "Passwort angeben", pwcheck: "Das Passwort entspricht nicht den Kriterien!", minlength: "Das Passwort entspricht nicht den Kriterien!" }, password2: { required: "Passwort wiederholen", equalTo: "Die Passwörter stimmen nicht überein" }, mail1: { required: "Mail-Adresse angeben", email: "ungültiges Mail-Format" }, mail2: { required: "Mail-Adresse wiederholen", equalTo: "Die Mail-Adressen stimmen nicht überein" } } }); $.validator.addMethod("pwcheck", function(value, element) { return /^[A-Za-z0-9\d=!\-@._*]+$/.test(value); }); }); </script>

  • How can I load a view based on how long I hold a UIButton?

    - by Thomas
    Hello all, I've searched the net and documentation, but haven't found anything quite like what I'm trying to do. I'm working on an app where I want to load one view if a UIButton is held for x seconds, another if it's held for x+y seconds, etc. I found this tutorial. The problem I'm running into is, how do I switch the length of the button press? The tutorial switched the number of taps. -(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { NSSet *allTouches = [event allTouches]; switch ([allTouches count]) { case 1: // Single touch { // Get the first touch. UITouch *touch = [[allTouches allObjects] objectAtIndex:0]; switch ([touch tapCount]) { case 1: // Single Tap. { // Start a timer timer = [NSTimer scheduledTimerWithTimeInterval:2 target:self selector:@selector(showAlertView:) userInfo:nil repeats:NO]; [timer retain]; } break; case 2: // Double tap. break; } } break; case 2: // Double touch { } break; default: break; } } Any suggestions? Thanks! Thomas

  • String.Format Phone Numbers with Extension

    - by ChiliYago
    I am trying to create a an function that formats US phone numbers -- hopefully without looping through each digit. When 10 digits are passed in all is fine. How ever when more than 10 digits are passed in I want the String.Format method to append the extension digits on the right. For example: When 14 digits passed in the result should be:(444)555-2222 x8888 When 12 digits passed in the result should be:(444)555-2222 x88 etc. However what I get with my current attempt is: Passing in 12 digits returns this string '() -949 x555444433' here is what I have so far. public static string _FormatPhone(object phonevalue) { Int64 phoneDigits; if (Int64.TryParse(phonevalue.ToString(), out phoneDigits)) { string cleanPhoneDigits = phoneDigits.ToString(); int digitCount = cleanPhoneDigits.Length; if (digitCount == 10) return String.Format("{0:(###) ###-####}", phoneDigits); else if (digitCount > 10) return String.Format("{0:(###) ###-#### x#########}", phoneDigits); else return cleanPhoneDigits; } return "Format Err#"; } Thanks in advance.

  • Overwriting lines in file in C

    - by KáGé
    Hi, I'm doing a project on filesystems on a university operating systems course, my C program should simulate a simple filesystem in a human-readable file, so the file should be based on lines, a line will be a "sector". I've learned, that lines must be of the same length to be overwritten, so I'll pad them with ascii zeroes till the end of the line and leave a certain amount of lines of ascii zeroes that can be filled later. Now I'm making a test program to see if it works like I want it to, but it doesnt. The critical part of my code: file = fopen("irasproba_tesztfajl.txt", "r+"); //it is previously loaded with 10 copies of the line I'll print later in reverse order /* this finds the 3rd line */ int count = 0; //how much have we gone yet? char c; while(count != 2) { if((c = fgetc(file)) == '\n') count++; } fflush(file); fprintf(file, "- . , M N B V C X Y Í U Á É L K J H G F D S A Ú O P O I U Z T R E W Q Ó Ü Ö 9 8 7 6 5 4 3 2 1 0\n"); fflush(file); fclose(file); Now it does nothing, the file stays the same. What could be the problem? Thank you.

  • Dynamically created operators

    - by Gero
    I created a program using dev-cpp and wxwidgets which solves a puzzle. The user must fill the operations blocks and the results blocks, and the program will solve it. Im solving it using bruteforce, i generate all non repeated 9 length number combinations using a recursive algorithm. It does it pretty fast. Up to here all is great! But the problem is when my program operates depending the character on the blocks. Its extremely slow (it never gets the answer), because of the chars comparation against +, -, *, etc. Im doing a CASE. Is there some way or some programming language wich allows dinamic creation of operators? So i can define the operator ROW1COL2 to be a +, and the same way to all other operations. I leave a screenshot of the app, so its easier to understand how the puzzle works. http://www.imageshare.web.id/images/9gg5cev8vyokp8rhlot9.png PD: The algorithm works, i tryed it with a trivial puzzle, and solved it in a second.

  • How does this Switch statement know which case to execute? (PHP/MySQL)

    - by ggfan
    Here is a code form a PHP+MySQL book I am reading and I am having trouble understanding this code. This code is about checking a file uploaded into a database. (Please excuse any spelling errors if any, I was typing it in) Q1: How does it know which case to echo? In the whole code, there is no mention of each case. Q2: Why do they skip case 5?! Or does it not matter which numbers you use(so I can have case 1, case 18, case 2?) if($_FILES['userfile']['error']>0) { echo 'Problem: '; switch($_FILES['userfile']['error']) { case 1: echo 'File exceeded upload_max_filesize'; break; case 2: echo 'File exceeded max_file_size'; break; case 3: echo 'File only partially uploaded'; break; case 4: echo 'No file uploaded'; break; case 6: echo 'Cannot upload file: no temp directory specified'; break; case 7: echo 'Upload failed: Cannot write to disk'; break; } exit; }

    Hi Everyone, Im working in a game and when the player finished the level , Im asking the Player to enter his name on EditText in Alert Dialog : AlertDialog.Builder builder = new Builder(this); LayoutInflater inflater = getLayoutInflater(); // Inflate and set the layout for the dialog // Pass null as the parent view because its going in the dialog layout builder.setView(inflater.inflate(R.layout.dialog_name, null)) // Add action buttons .setPositiveButton(R.string.alertName, new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int id) { playerText = (EditText) ((AlertDialog)dialog).findViewById(R.id.username); if(playerText.getText() != null && playerText.getText().length() != 0) Helper.currentPlayer.setName(playerText.getText().toString()); //calculate the score // save in data base PlayerDataSource playerDS = new PlayerDataSource(getApplicationContext()); playerDS.open(); Helper.currentPlayer = playerDS.createPlayer(Helper.currentPlayer.getName(), Helper.currentPlayer.getScore(), Helper.currentPlayer.levels, Helper.currentPlayer.times, LanguageHelper.div); playerDS.close(); saveStmc(); mainScene.setChildScene(choicesMenu, false, true, true); } }) .setTitle("Please Enter Your name") .setNegativeButton(R.string.cancel, new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int id) { } }); alert = builder.create(); When the Player enters his name and press OK (Positive button) I will check in database if the name exists or not, if the name is exist : show Toast and not dismiss the alert to write another name. How to do that?

  • Tricky file parsing. Inconsistent Delimeters

    - by Ben Truby
    I need to parse a file with the following format. 0000000 ...ISBN.. ..Author.. ..Title.. ..Edit.. ..Year.. ..Pub.. ..Comments.. NrtlExt Nrtl Next Navg NQoH UrtlExt Urtl Uext Uavg UQoH ABS NEB MBS FOL ABE0001 0-679-73378-7 ABE WOMAN IN THE DUNES (INT'L ED) 1st 64 RANDOM 0.00 13.90 0.00 10.43 0 21.00 10.50 6.44 3.22 2 2.00 0.50 2.00 2.00 ABS The ID and ISBN are not a problem, the title is. There is no set length for these fields, and there are no solid delimiters- the space can be used for most of the file. Another issue is that there is not always an entry in the comments field. When there is, there are spaced within the content. So I can get the first two, and the last fourteen. I need some help figuring out how to parse the middle six fields. This file was generated by an older program that I cannot change. I am using php to parse this file.

  • Java: dangerous self-returning-recursive function by IOException?

    - by HH
    I had very errorsome Exception handling with if-clauses. An exception occurs if not found path. An exception returns the function again. The function is recursive. Safe? $ javac SubDirs.java $ java SubDirs Give me an path. . HELLO com TOASHEOU google common annotations base collect internal Give me an path. IT WON'T FIND ME, SO IT RETURNS ITSELF due to Exception caught Give me an path. $ cat SubDirs.java import java.io.*; import java.util.*; public class SubDirs { private List<File> getSubdirs(File file) throws IOException { List<File> subdirs = Arrays.asList(file.listFiles(new FileFilter() { public boolean accept(File f) { return f.isDirectory(); } })); subdirs = new ArrayList<File>(subdirs); List<File> deepSubdirs = new ArrayList<File>(); for(File subdir : subdirs) { deepSubdirs.addAll(getSubdirs(subdir)); } subdirs.addAll(deepSubdirs); return subdirs; } public static void search() { try{ BufferedReader in = new BufferedReader(new InputStreamReader(System.in)); String s; System.out.println("Give me an path."); while ((s = in.readLine()) != null && s.length() != 0){ SubDirs dirs = new SubDirs(); List<File> subDirs = dirs.getSubdirs(new File(s)); for ( File f : subDirs ) { System.out.println(f.getName()); } System.out.println("Give me an path."); } }catch(Exception e){ // Simple but is it safe? search(); } } public static void main(String[] args) throws IOException { search(); } }

  • WMI Query Script as a Job

    - by Kenneth
    I have two scripts. One calls the other with a list of servers as parameters. The second query is designed to execute a WMI query. When I run it manually, it does this perfectly. When I try to run it as a job it hangs forever and I have to remove it. For the sake of space here is the relevant part of the calling script: ProcessServers.ps1 Start-Job -FilePath .\GetServerDetailsLight.ps1 -ArgumentList $sqlsrv,$destdb,$server,$instance GetServerDetailsLight.ps1 param($sqlsrv,$destdb,$server,$instance) $password = get-content C:\SQLPS\auth.txt | convertto-securestring $credentials = new-object -typename System.Management.Automation.PSCredential -argumentlist "DOMAIN\MYUSER",$password [System.Reflection.Assembly]::LoadWithPartialName('Microsoft.SqlServer.SMO') $box_id = 0; if ($sqlsrv.length -eq 0) { write-output "No data passed" break } function getinfo { param( [string]$svr, [string]$inst ) "Entered GetInfo with: $svr,$inst" $cs = get-wmiobject win32_operatingsystem -computername $svr -credential $credentials -authentication 6 -Verbose -Debug | select Name, Model, Manufacturer, Description, DNSHostName, Domain, DomainRole, PartOfDomain, NumberOfProcessors, SystemType, TotalPhysicalMemory, UserName, Workgroup write-output "WMI Results: $cs" } getinfo $server $instance write-output "Complete" Executed as a job it will show as 'running' forever: PS C:\sqlps> Start-Job -FilePath .\GetServerDetailsLight.ps1 -ArgumentList DBSERVER,LOGDB,SERVER01,SERVER01 Id Name State HasMoreData Location Command -- ---- ----- ----------- -------- ------- 21 Job21 Running True localhost param($sqlsrv,$destdb,... GAC Version Location --- ------- -------- True v2.0.50727 C:\WINDOWS\assembly\GAC_MSIL\Microsoft.SqlServer.Smo\10.0.0.0__89845dcd8080cc91\Microsoft.SqlServer.Smo.dll getinfo MSDCHR01 MSDCHR01 Entered GetInfo with: SERVER01,SERVER01 The last output I ever get is the 'Entered GetInfo with: SERVER01,SERVER01'. If I run it manually like so: PS C:\sqlps> .\GetServerDetailsLight.ps1 DBSERVER LOGDB SERVER01 SERVER01 The WMI query executes just as expected. I am trying to determine why this is, or at least a useful way to trap errors from within jobs. Thanks!

  • Generate number sequences with LINQ

    - by tanascius
    I try to write a LINQ statement which returns me all possible combinations of numbers (I need this for a test and I was inspired by this article of Eric Lippert). The method's prototype I call looks like: IEnumerable<Collection<int>> AllSequences( int start, int end, int size ); The rules are: all returned collections have a length of size number values within a collection have to increase every number between start and end should be used So calling the AllSequences( 1, 5, 3 ) should result in 10 collections, each of size 3: 1 2 3 1 2 4 1 2 5 1 3 4 1 3 5 1 4 5 2 3 4 2 3 5 2 4 5 3 4 5 Now, somehow I'd really like to see a pure LINQ solution. I am able to write a non LINQ solution on my own, so please put no effort into a solution without LINQ. My tries so far ended at a point where I have to join a number with the result of a recursive call of my method - something like: return from i in Enumerable.Range( start, end - size + 1 ) select BuildCollection(i, AllSequences( i, end, size -1)); But I can't manage it to implement BuildCollection() on a LINQ base - or even skip this method call. Can you help me here?
