  • jquery .children() returning wrong size

    - by i need help
    Hi guys, I just found the children size not consistent. Below attach full code with alert, for easy reference. Is the way I get the data wrong? <body> <table width="100" border="0" cellspacing="0" cellpadding="0"> <tr> <td height="30" valign="top"><strong>Header Title</strong></td> </tr> <tr> <td height="32" valign="top">Date : <strong>01/01/2010 </strong> <br><div><b></b></div><span></span></td> </tr> </table> </body> $("td").each(function() { alert($(this).children().size()); }); //first td showing 1 direct children- <strong> //second td showing 4 direct children- <strong> <br> <div> <span> ----- $("tr").each(function() { alert($(this).children().size()); }); //first tr showing 1 direct children - <td> //second tr showing 1 direct children - <td> ----- $("table").each(function() { alert($(this).children().size()); }); // ERROR // this table showing 1 direct children only.... something WRONG. // I thought there are 2 <tr> inside this table?

  • Beginner error in CUDA

    - by Dimitri
    Hi folks, first all i want to wish you a merry christmas. I am writing a small program in CUDA and i have the following errors : contraste.cu(167): error: calling a host function from a __device__/__global__ function is not allowed I don't understand why. Can you please help me and show me my errors. It seems that my program is correct. Here is a the bunch of code causing the problems : __global__ void kernel_contraste(float power, unsigned char tab_in[], unsigned char tab_out[], int nbl, int nbc) { int x = threadIdx.x; printf("I am the thread %d\n", x); } Part of my main program : unsigned char *dimg, *dimg_res; ..... cudaMalloc((void **)dimg, h * w * sizeof(char)); cudaMemcpy(dimg, r.data, h*w*sizeof(char), cudaMemcpyHostToDevice); cudaMalloc((void **)dimg_res, h*w*sizeof(char)); dim3 nbThreadparBloc(256); dim3 numblocs(1); kernel_contraste<<<numblocs, nbThreadparBloc >>>(puissance, dimg, dimg_res, h, w); cudaThreadSynchronize(); ..... cudaFree(dimg); cudaFree(dimg_res); The line 167 is the line where i call the printf in function kernel_contraste. For information, this program takes an image as an input( a sun Rasterfile ) and a power then it calculates the contraste of that image. Thanks !!

  • Redirect To Another Site With Header Information Attached Javascript

    - by Nick LaMarca
    I am trying to make a client side click and redirect to another site with header information added, my client side code for the onclick is this: function selectApp(appGUID, userId ,embedUrl) { if(embedUrl==="") { var success = setAppGUID(appGUID); window.location.replace('AppDetail.aspx'); } else { $.ajax({ type: "POST", url: embedUrl, contentType: "text/html", beforeSend: function (xhr, settings) { xhr.setRequestHeader("UserId", userId); }, success: function (msg) { //go to slx window.location.replace(embedUrl); } }); } } And the server side code in "embedUrl" is protected void Page_Load(object sender, EventArgs e) { string isSet = (String)HttpContext.Current.Session["saveUserID"]; if (String.IsNullOrEmpty(isSet)) { NameValueCollection headers = base.Request.Headers; for (int i = 0; i < headers.Count; i++) { if (headers.GetKey(i).Equals("UserId")) { HttpContext.Current.Session["saveUserID"] = headers.Get(i); } } } else { TextBox1.Text = HttpContext.Current.Session["saveUserID"].ToString(); } } This seems to work but its not too elegant. Is there a way to redirect with header data? Without (what Im doing) Saving header info in a session var then doing a redirect in 2 seperate pieces.

  • jquery an div tags used in a ordered list

    - by shan2on
    hello everyone, i'm not sure where my errors are lying but here is my scenario... i have an un-ordered list in html that handles my main link bar... <ul id="navlist"> <li><a href="/" id="current">home</a></li> <li><a href="#" id="search">search</a></li> <li><a href="#" id="users">login</a></li> </ul> and what i want done is to call each id and have jQuery handle each and dislpay it where specified in my css file... for now, lets just ignore my "home" link... here is a snippet of my inline jquery $(document).ready(function() { $("a").click(function () { $("div#login").slideToggle("fast"); }); }) Now, whichever div i specify, it calls that ... however it will only call one div, using either from the un-orderd list, as mentioned above in the html. My Goal is to call a search bar when search is clicked, and to call a login box when login is clicked. to my knowledge (noob), i believe use an as a class, however that is what brings me here. i believe my error is in my jquery and not my css, as stated above, either instance will be displayed when the jquery function calls either tag. any help is greatly appreciated. thanks in advance shan2on

  • How to iteratively generate k elements subsets from a set of size n in java?

    - by Bea Metitiri
    Hi, I'm working on a puzzle that involves analyzing all size k subsets and figuring out which one is optimal. I wrote a solution that works when the number of subsets is small, but it runs out of memory for larger problems. Now I'm trying to translate an iterative function written in python to java so that I can analyze each subset as it's created and get only the value that represents how optimized it is and not the entire set so that I won't run out of memory. Here is what I have so far and it doesn't seem to finish even for very small problems: public static LinkedList<LinkedList<Integer>> getSets(int k, LinkedList<Integer> set) { int N = set.size(); int maxsets = nCr(N, k); LinkedList<LinkedList<Integer>> toRet = new LinkedList<LinkedList<Integer>>(); int remains, thresh; LinkedList<Integer> newset; for (int i=0; i<maxsets; i++) { remains = k; newset = new LinkedList<Integer>(); for (int val=1; val<=N; val++) { if (remains==0) break; thresh = nCr(N-val, remains-1); if (i < thresh) { newset.add(set.get(val-1)); remains --; } else { i -= thresh; } } toRet.add(newset); } return toRet; } Can anybody help me debug this function or suggest another algorithm for iteratively generating size k subsets? EDIT: I finally got this function working, I had to create a new variable that was the same as i to do the i and thresh comparison because python handles for loop indexes differently.

  • Undefined test not working in javascript.

    - by James South
    I'm getting the error 'foo' is undefined. in my script when i test my function with an undefined parameter. As far as I understand, This shouldn't be happening. My calling code: //var foo var test = peachUI().stringIsNullOrEmpty(foo) ; My function (part of a larger framework). stringIsNullOrEmpty: function (testString) { /// <summary> /// Checks to see if a given string is null or empty. /// </summary> /// <param name="testString" type="String"> /// The string check against. /// </param> /// <returns type="Boolean" /> var $empty = true; if (typeof testString !== "undefined") { if (testString && typeof testString === "string") { if (testString.length > 0) { $empty = false; } } } return $empty; } Any ideas? Please note. I've had a good read of other similar questions before posting this one.

  • jQuery menu animation

    - by bomortensen
    Hi Stackoverflow, I'm building a website where I'm using jQuery to animate a horizontal tabbed menu. What I want to achieve can be seen here: / link removed / If you hover/mouseover the "Link 1" tab, you'll see that a white div is expanding. Each of the tab menu items are a styled li-tag. What I want to do is, that when you hover/mouseover i.e. the "Link 2" tab, the white div contracts and then expands again with content related to "Link 2" instead of "Link 1". Also, the "Link 1" tab should be expanded by default (i.e. when you just entered the site) Does any of you jQuery ninjas out there know how to do this? What I currently have is this: <script type="text/javascript"> $(document).ready(function(){ var $div = $('#divtest'); var height = $div.height(); $div.hide().css({ height : 0 }); $('#forside').hover(function () { if ($div.is(':visible')) { $div.animate({ height: 0 }, { duration: 200, complete: function () { $div.hide(); } }); } else { $div.show().animate({ height : height }, { duration: 200 }); } return false; }); }); </script> Do I need to have 4 different div's which expands/contracts for every mouseover? If i'm not being clear about what my problem is, please say so and I'll try to elaborate :) Thanks in advance!

  • I just wanted to DES 4096 bytes of data with a 128 bits key...

    - by badp
    ...and what the nice folks at OpenSSL gratiously provide me with is this. :) Now, since you shouldn't be guessing when using cryptography, I come here for confirmation: what is the function call I want to use? What I understood A 128 bits key is 16 byte large, so I'll need double DES (2 × 8 byte). This leaves me with only a few function calls: void DES_ede2_cfb64_encrypt(const unsigned char *in, unsigned char *out, long length, DES_key_schedule *ks1, DES_key_schedule *ks2, DES_cblock *ivec, int *num, int enc); void DES_ede2_cbc_encrypt(const unsigned char *input, unsigned char *output, long length, DES_key_schedule *ks1, DES_key_schedule *ks2, DES_cblock *ivec, int enc); void DES_ede2_cfb64_encrypt(const unsigned char *in, unsigned char *out, long length, DES_key_schedule *ks1, DES_key_schedule *ks2, DES_cblock *ivec, int *num, int enc); void DES_ede2_ofb64_encrypt(const unsigned char *in, unsigned char *out, long length, DES_key_schedule *ks1, DES_key_schedule *ks2, DES_cblock *ivec, int *num); In this case, I guess the function I want to call DES_ede2_cfb64_encrypt, although I'm not so sure -- I definitely don't need padding here and I'd have to care about what ivec and num are, and how I want to generate them... What am I missing?

  • jQuery: How do I rewrite .after( content, content )?

    - by Evan Carroll
    I've got this form working, but according to my previous question it might not be supported: it isn't in the docs either way -- but the intention is pretty obvious in the code. $(".section.warranty .warranty_checks :last").after( $('<div class="little check" />').click( function () { alert('hi') } ) , $('<span>OEM</span>') /*Notice this (a second) argument */ ); What this does is insert <div class="little check"> with a simple .click() callback, followed by a sibling of <span>OEM</span>. How else can I write this then? I'm having difficulty conjuring something working by chaining any combination of .after(), and .insertAfter()? I would expect this to work, but it doesn't: $(".section.warranty .warranty_checks :last").after( $('<div class="little check" />').click( function () { alert('hi') } ).after ( $('<span>OEM</span>') ) ); I would also expect this to work, but it doesn't: $(".section.warranty .warranty_checks :last").after( $('<span>OEM</span>').insertAfter( $('<div class="little check" />').click( function () { alert('hi') } ) ); );

  • retrieve only sub-pages (wordpress)

    - by Radek
    I want to list all sub-pages only one level though of one particular page. I was reading Function Reference/get pages and thought that $pages = get_pages( array( 'child_of' => $post->ID, 'parent' => $post->ID)) ; will do the trick but it is not working. It lists all pages on the same level like the page I call that code from. If I omit parent option I will get all pages even with sub-pages that I want. But I want only sub-pages. The whole function is like function about_menu(){ if (is_page('about')){ $pages = get_pages( array( 'child_of' => $post->ID, 'parent' => $post->ID)) ; foreach($pages as $page) { ?> <h2><a href="<?php echo get_page_link($page->ID) ?>"><?php echo $page->post_title ?></a></h2> <?php } } } and mine is second one

  • Will array_unique work also with array of objects?

    - by Richard Knop
    Is there a better way than using array-walk in combination with unserialize? I have two arrays which contain objects. The objects can be same or can be different. I want to merge both arrays and keep only unique objects. This seems to me like a very long solution for something so trivial. Is there any other way? class Dummy { private $name; public function __construct($theName) {$this->name=$theName;} } $arr = array(); $arr[] = new Dummy('Dummy 1'); $arr[] = new Dummy('Dummy 2'); $arr[] = new Dummy('Dummy 3'); $arr2 = array(); $arr2[] = new Dummy('Dummy 1'); $arr2[] = new Dummy('Dummy 2'); $arr2[] = new Dummy('Dummy 3'); function serializeArrayWalk(&$item) { $item = serialize($item); } function unSerializeArrayWalk(&$item) { $item = unserialize($item); } $finalArr = array_merge($arr, $arr2); array_walk($finalArr, 'serializeArrayWalk'); $finalArr = array_unique($finalArr); array_walk($finalArr, 'unSerializeArrayWalk'); var_dump($finalArr);

  • Pipelining String in Powershell

    - by ChvyVele
    I'm trying to make a simple PowerShell function to have a Linux-style ssh command. Such as: ssh username@url I'm using plink to do this, and this is the function I have written: function ssh { param($usernameAndServer) $myArray = $usernameAndServer.Split("@") $myArray[0] | C:\plink.exe -ssh $myArray[1] } If entered correctly by the user, $myArray[0] is the username and $myArray[1] is the URL. Thus, it connects to the URL and when you're prompted for a username, the username is streamed in using the pipeline. Everything works perfectly, except the pipeline keeps feeding the username ($myArray[0]) and it is entered as the password over and over. Example: PS C:\Users\Mike> ssh xxxxx@yyyyy login as: xxxxx@yyyyy's password: Access denied xxxxx@yyyyy's password: Access denied xxxxx@yyyyy's password: Access denied xxxxx@yyyyy's password: Access denied xxxxx@yyyy's password: Access denied xxxxx@yyyyy's password: FATAL ERROR: Server sent disconnect message type 2 (protocol error): "Too many authentication failures for xxxxx" Where the username has been substituted with xxxxx and the URL has been substituted with yyyyy. Basically, I need to find out how to stop the script from piping in the username ($myArray[0]) after it has been entered once. Any ideas? I've looked all over the internet for a solution and haven't found anything.

  • jQuery .height() property not working

    - by Andrew
    I'm attempting to get the height of an element using jQuery, but am receiving some unexpected results. Here's the code: $(function() { var contentheight = $('#subpage-content-small').height; alert(contentheight); }); Where #subpage-content-small has these CSS properties: #subpage-content-small { width: 400px; float: left; margin: 30px 10px 0 0; padding-bottom: 45px; } What I'm getting as an output for my alert is the following: function (f) { var e = this[0]; if (!e) { return f == null ? null : this; } if (c.isFunction(f)) { return this.each(function (j) {var i = c(this);i[d](f.call(this, j, i[d]()));}); } return "scrollTo" in e && e.document ? e.document.compatMode === "CSS1Compat" && e.document.documentElement["client" + b] || e.document.body["client" + b] : e.nodeType === 9 ? Math.max(e.documentElement["client" + b], e.body["scroll" + b], e.documentElement["scroll" + b], e.body["offset" + b], e.documentElement["offset" + b]) : f === w ? c.css(e, d) : this.css(d, typeof f === "string" ? f : f + "px"); } Any idea why I'm getting this as opposed to an integer of the height? Thanks in advance!

  • Custom Tile Layer Problem

    - by Myra
    Hi,I'm currently implementing logic on custom tile layers via OpenLayers function getTiles() { var res = this.map.getResolution(); var x = Math.round((bounds.left - this.maxExtent.left) / (res * this.tileSize.w)); var y = Math.round((this.maxExtent.top - bounds.top) / (res * this.tileSize.h)); var z = this.map.getZoom(); return ......; } What I need to is to carry this code in Google API v3. As I searched documentation I found this code to work with: var customtile = new google.maps.ImageMapType({ getTileUrl: function (coord, zoom) { .... .... } Unfortonately,I cannot convert logic in OpenLayers code to Google. As I know resolution is 180 * tileSize.w / Math.pow(2, zoom) //where tileSize is 256x256 Since Google projection is same with my tiles WGS84 boundary should be -180,-90,90,180 I need to calculate to extent coordinates,but in function getTileUrl,there are two arguments.One of which is zoom,but the other coord is some x,y pair which I dont understand what that is.What is that exactly ? How can I generalize formula for calculating tile numbers in Google Maps? Thank you Myra

  • Is there a jQuery Equivalent of YUI 2 Custom Event Publish/Subscribe Event Model?

    - by Abe
    Hello! I learned how to develop in Javascript using the YUI 2 library and was wondering if there is a jQuery equivalent of Custom Events (http://developer.yahoo.com/yui/event/#customevent) Specifically, I want to be able to define custom events without having to attach the listeners initially. In YUI, I would create a page class and declare different custom events that can be subscribed to. Below is some example code to demonstrate what I want to do, but with jQuery function ListPage() { var me = this; this.initEvent = new YAHOO.util.CustomEvent("initEvent"); this.init = function() { // initialize events, DOM, etc this.initEvent.fire(me); } } In application Javascript, I would then like to subscribe to the initEvent. var page = new ListPage(); page.initEvent.subscribe( function (type, args) { // do stuff here } ); page.init(); Are there any tutorials/examples of something this in jQuery? I understand I can do something similar using bind() and trigger(), but the impression I get is I have to pass in the event handler when I call bind(). Is it possible in jQuery to create the custom event, but pass in the event handler later? I hope my question makes sense. thanks!

  • Concatenate an each loop inside another

    - by Lothar
    I want to to concatenate the results of a jquery each loop inside of another but am not getting the results I expect. $.each(data, function () { counter++; var i = 0; var singlebar; var that = this; tableRow = '<tr>' + '<td>' + this.foo + '</td>' + $.each(this.bar, function(){ singlebar = '<td>' + that.bar[i].baz + '</td>'; tableRow + singlebar; }); '</tr>'; return tableRow; }); The portion inside the nested each does not get added to the string that is returned. I can console.log(singlebar) and get the expected results in the console but I cannot concatenate those results inside the primary each loop. I have also tried: $.each(this.bar, function(){ tableRow += '<td>' + that.bar[i].baz + '</td>'; }); Which also does not add the desired content. How do I iterate over this nested data and add it in the midst of the table that the primary each statement is building?

  • Text replacement for multiple script/config files

    - by user343804
    I am doing some sort of science with a combination of Python, bash scripts and configuration files with weird syntaxes from old C programs. To run different tests, I have to tune (open text file, edit and save) a number of these files, but it is getting harder and harder to remember which files to edit. Also, the tasks are very repetitive and I end having a bunch of comment lines, switching on and off the settings for a specific run. I dream of a tool that can keep a list of files (regardless of the file format) and allow me to centrally choose from a predefined list of "profiles", taking care of editing the script/config files. For example lets say I have a config and script file: config.cfg var1 = 1.0 #var1 = 1.5 script.sct function(200.0) #function(300.0) I would like to instead have auxiliary text files: config.cfg.tem var1 = $$var1$$ script.sct.tem function($$par1$$) and in a central script or even better, a GUI, just switch from profile1 (e.g. var1=1.0,par1=200.0) to profile2 (e.g. var1=1.5,par1=300.0), and the tool to automatically update the text files. Any idea if such a tools exists?

  • Receiving "expected expression before" Error When Using A Struct

    - by Zach Dziura
    I'm in the process of creating a simple 2D game engine in C with a group of friends at school. I'd like to write this engine in an Object-Oriented way, using structs as classes, function pointers as methods, etc. To emulate standard OOP syntax, I created a create() function which allocates space in memory for the object. I'm in the process of testing it out, and I'm receiving an error. Here is my code for two files that I'm using to test: test.c: #include <stdio.h> int main() { typedef struct { int i; } Class; Class *test = (Class*) create(Class); test->i = 1; printf("The value of \"test\" is: %i\n", test->i); return 0; } utils.c: #include <stdio.h> #include <stdlib.h> #include "utils.h" void* create(const void* class) { void *obj = (void*) malloc(sizeof(class)); if (obj == 0) { printf("Error allocating memory.\n"); return (int*) -1; } else { return obj; } } void destroy(void* object) { free(object); } The utils.h file simply holds prototypes for the create() and destroy() functions. When I execute gcc test.c utils.c -o test, I'm receiving this error message: test.c: In function 'main': test.c:10:32: error: expected expression before 'Class' I know it has something to do with my typedef at the beginning, and how I'm probably not using proper syntax. But I have no idea what that proper syntax is. Can anyone help?

  • Objective-C Result from a Static Method saved to class instance variable giving "EXC_BAD_ACCESS" when used.

    I am trying to store the md5 string as a class instance variable instead of the actual password. I have a static function that will return a md5 string which I'm trying to store in an instance variable instead of the actual password. I have the following setter for my class instance variable: -(void)setPassword:(NSString *)newpass{ if(newpass != password){ password = [utils md5HexDigest:newpass]; } } This will pass back the correct md5 string and save it to the password variable in my init function: [self setPassword:pword];. If I call another instance method and try to access self.password" I will get "EXC_BAD_ACCESS". I understand that the memory is getting released, but I have no clue to make sure it stays. I have tried alloc init with autorelease with no luck. This is the md5HexDigest function getting called during the init (graciously found in another stackoverflow question): + (NSString*)md5HexDigest:(NSString*)input { const char* str = [input UTF8String]; unsigned char result[CC_MD5_DIGEST_LENGTH]; CC_MD5(str, strlen(str), result); NSMutableString *ret = [NSMutableString stringWithCapacity:CC_MD5_DIGEST_LENGTH*2]; for(int i = 0; i<CC_MD5_DIGEST_LENGTH; i++) { [ret appendFormat:@"%02x",result[i]]; } return ret; } Any help/pointers would be greatly appreciated. I would rather have the md5 string saved in memory than the actual password calling the md5 every time I needed to use the password. Thanks in advance.
