  • looping thru a list of checkboxes and saving the values, now working properly

    - by Erez
    Hello all, I'm having a bit of a problem with this code. The program gives me a list of checkboxes but a user ID. then u user can change his selection and push the save button (id="btnSaveUserIntersts") and i am trying to save in the hidden textbox all the values of the checkboxes that was choosen. The problem is that i am getting all the time the same selections that came form the database and not getting the new selection that the user made. Can any one tell me what am i doing wrong here? $(document).ready( function() { $('#btnSaveUserIntersts').bind( 'click', function() { var strCheckBoxChecked = new String(); $('input[type=checkbox][checked]').each( function() { strCheckBoxChecked += $(this).val(); strCheckBoxChecked += ','; } ); $('#hidUserInterests').val(strCheckBoxChecked); } ); } ); 10x

  • When is a Cocoa callback given controll?

    - by Kaspa
    Hi, I've been searching around the web for an answer to this one, but was unable to find an answer, on the other side I think it's something quite common thus there is a possibility I'm missing some keywords here. Anyhow, the problem is as follows: When is control given to a callback function in ObjC (iPhone)? Does it happen after control is given to a high up in the hierarchy class responsible for the runloop? Can it occur in the middle of another function call being executed? As an example, let's take the NSURLConnection, we don't know or can't predict when it's going to call didReceiveResponse or the other callback methods, can it be the case that didReceiveResponse get's called when I'm in the middle of another function? (highly doubt that but was unable to find information on callbacks wating for the end of the run loop) Cheers, Kaspa

  • Submit form if ajax validator returns true using jquery

    - by Anthony
    I am not sure where I'm going wrong. The idea is that before the form is submitted, one of the input fields is sent to a server-side validator via ajax. If the response is 1, the input is valid and the form should be submitted. If the response is 0, the form should not be submitted. The issue is that I can't figure out how to set a variable within the ajax request function that will prevent the form from being submitted. This is what I have: $("#form").submit(function() { var valid= false; var input = $("#input").val(); $.ajax({ type: "POST", url: "validator.php", data: "input=" + input, success: function(msg){ valid = (msg == 1) ? true : false; if(!valid) { $("#valid_input").html("Please enter valid info"); } else { $("#valid_input").html(""); } } }); return valid; });

  • Azure Service Bus Scalability

    - by phebbar
    I am trying to understand how can I make Azure Service Bus Topic to be scaleable to handle 10,000 requests/second from more than 50 different clients. I found this article at Microsoft - http://msdn.microsoft.com/en-us/library/windowsazure/hh528527.aspx. This provides lot of good input to scale azure service bus like creating multiple message factories, sending and receiving asynchronously, doing batch send/receive. But all these input are from the publisher and subscriber client perspective. What if the node running the Topic can not handle the huge number of transactions? How do I monitor that? How do I have the Topic running on multiple nodes? Any input on that would be helpful. Also wondering if any one has done any capacity testing with Topic/Queue and I am eager to see those results... Thanks, Prasanna

  • jquery issues - it wont change it accordingly

    - by chuck
    My coding isnt linking properly , its meant to use jquery to detect the OS and change the link accordingly , however it isn't. In my HTML page I have it linked in the header as <script src="jsquery.js" type="text/javascript"></script> which loads up my jsquery now $(document).ready(function() { if (navigator.appVersion.indexOf("Win") != -1) { // Computers runs windows $("a[href$='.pdf']").each(function() { this.href = this.href.replace("Volumes", "KP01DS0194TG"); }); } if (navigator.appVersion.indexOf("Mac") != -1) { // computer is a Mac $("a[href$='.pdf']").each(function() { this.href = this.href.replace("KP01DS0194TG", "Volumes"); }); } }); Yet on Mac's it still tries to connect to KP01DS0194TG and not to Volumes - it doesnt change it - how can I get it to recognize the OS and change it accordingly?

  • wxPython formatting questions

    - by Kevin
    I have an app I was working on to learn more about wxPython( I have been primarily been a scripter ). I forgot about it now I am opening it back up. It's a screen scraper, and I have it working almost the way I want it, going to build a regex parser to strip out the links in every scrape that I don't need. The questions I have are this. In it current state, if I check more than one site, it goes out and scrapes, and returns it in separate windows, the for:each section in the Clicked function. I want to put them in a frame, in the window, altogether. I also want to know if I can take the list they are read into and send it to a checklist, so someone could check off separate items, I want to build a save function and keep certain ones. In regards to a save function, I want to keep saved checks, are there calls to the widgets to save their states? I know it's a lot, but thanks for the help.

  • Embedded Java Databases for Large Data Sets

    - by ExAmerican
    I would like to port a PHP/MySQL-based client/server application to be a standalone desktop application written in Java. The database has grown to be fairly large, with several tables with hundreds of thousands of rows. I expect these could grow to over a million entries for certain tables. What embedded database would best handle this? HSQLDB and Sqlite seem to be the obvious choices, though I'm guessing there are others out there as well. My main priorities are the ability to perform queries on large amounts of data efficiently (this thread seems to confirm Sqlite can handle this) and the ease with which I can import old data from MySQL (I remember HSQLDB being kind of a pain for that). Note: I am aware that similar questions comparing embedded databases have been posted before (for example here and here) but as my priorities differ somewhat from most applications considering the large data migration I thought it justified a new question.

  • C - memset segfault for statically allocated char array

    - by user1327031
    I get a segfault when trying to memset an array of chars that was allocated statically, but not for an array of the same length that was allocated using malloc. variable definitions: //static char inBuff[IN_BUFF_LEN]; //dynamic char * inBuffD; function call: //static, cast used because char** != char (*) [n] serverInit(portNum, (char**) &inBuff, &serv_addr, &sockfd) //dynamic serverInit(portNum, &inBuffD, &serv_addr, &sockfd) use within the function: memset(*inBuffAdr, 0, IN_BUFF_LEN); I suspect that my problem is in the difference of the function calls, or to be more precise, my incomplete understanding of the "char** != char (*) [n]" situation. But I have been banging at this for too long and can't see the forest from the trees so any hints and advice would be very appreciated.

  • jQuery: Listen to changes within a DIV and act accordingly

    - by Chris
    I have a function that grabs an XML document and transforms it according to an XSL document. It then places the result into a div with the id laneconfigdisplay. What I want to do is, separate to the transformation logic, setup a jQuery change event for that div so I can tell when it has changed, and run some jQuery code. I have tried the following, but it does not work! $(document).ready(function() { $('#laneconfigdisplay').change(function() { alert('woo'); }); //Do XML / XSL transformation here }); <!-- HTML code here --> <div id="laneconfigdisplay"></div> What am I doing wrong?

    - by milan
    The function: #define ASSOC(port) (*(volatile bit_field *) (&port)) The function call: #define SCLK ASSOC(PORTC).bit0 bit_field defined as a struct like this: typedef struct { unsigned char bit0 :1, bit1 :1, bit2 :1, bit3 :1, bit4 :1, bit5 :1, bit6 :1, bit7 :1; } bit_field; I don't know where &port is defined. Can someone please explain how the function is read and how it works please?

  • How do I sub sample data by group using ddply?

    - by Maiasaura
    I've got a data frame with far too many rows to be able to do a spatial correlogram. Instead, I want to grab 40 rows for each species and run my correlogram on that subset. I wrote a function to subset a data frame as follows: samp <- function(dataf) { dataf[sample(1:dim(dataf)[1], size=40, replace=FALSE),] } Now I want to apply this function to each species in a larger data frame. When I try something like culled_data = ddply (larger_data, .(species), subset, samp) I get this error: Error in subset.data.frame(piece, ...) : 'subset' must evaluate to logical Anyone got ideas on how to do this?

  • Uncaught syntax error: Adding <li> elements to an <ul>

    - by ThePagan
    I keep getting an uncaught syntex error which I know usually means your code has a missing closing something. I keep failing to see what it is that I am missing. The idea of the function is that it extracts the a links ID and Text content and add's it to an un-ordered list. The links have a class of 'ingredient_add' and the unordered list has an ID of 'ingredientsAdded'. I can't see what I've missed here. $(document).ready(function() { $('.ingredient_add').click(function() { event.preventDefault(); var id = this.id; var value = this.text(); $('#ingredientsAdded').append("<li id='"+id+"'>"+value+"</li>"); }); //end add to list }); // end document ready()

  • How to kill slave kernel securely?

    - by Alexey Popkov
    Hello, LinkClose[link] "does not necessarily terminate the program at the other end of the connection" as it is said in the Documentation. Is there a way to kill the process of the slave kernel securely? EDIT: In really I need a function in Mathematica that returns only when the process of the slave kernel has already killed and its memory has already released. Both LinkInterrupt[link, 1] and LinkClose[link] do not wait while the slave kernel exits. At this moment the only such function is seemed to be killProc[procID] function I had showed in one of answers at this page. But is there a built-in analog?

  • Javascript Inheritance and Arrays

    - by Inespe
    Hi all! I am trying to define a javascript class with an array property, and its subclass. The problem is that all instances of the subclass somehow "share" the array property: // class Test function Test() { this.array = []; this.number = 0; } Test.prototype.push = function() { this.array.push('hello'); this.number = 100; } // class Test2 : Test function Test2() { } Test2.prototype = new Test(); var a = new Test2(); a.push(); // push 'hello' into a.array var b = new Test2(); alert(b.number); // b.number is 0 - that's OK alert(b.array); // but b.array is containing 'hello' instead of being empty. why? As you can see I don't have this problem with primitive data types... Any suggestions?

  • jQuery - How to Prevent Animation Queue Buildup with Double Animations?

  • mod_rewrite: check if isn't a certain domain

    - by weingage
    I'm migrating some code from a working web app, but can't get it to work on the new server. Everything seems to be configured correctly, but I'm getting internal redirect limit errors in Apache2. Here are my rewrites and explanation This WORKS - any subdomains that aren't cdn. or manage. should be redirected to u.php RewriteCond %{HTTP_HOST} ^(^.*)\.mediasprk\.com$ [NC] RewriteCond ^(.*)$ !^(cdn|manage)$ RewriteCond %{REQUEST_URI} !\.(png|gif|jpg)$ RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^(.*)$ u.php?uri=$1&hostName=%{HTTP_HOST} This is no longer working. Goal here is to handle CName pointing. So if it's not my app domain (mediasprk.com), then handle it by sending it to u.php. RewriteCond %{HTTP_HOST} !^mediasprk\.com$ [NC] RewriteCond %{REQUEST_URI) !\.(png|gif|jpg)$ RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^(.*)$ u.php?uri=$1&hostName=%{HTTP_HOST} Can anyone see the issue here in the second block that would cause the redirect limit errors? Maybe something wrong in the rewrites? Thanks.

Anyway around this?
