  • My AJAX is only firing once,

    - by sea_1987
    Hi There, I ahave some ajax that is fired when a checkbox is clicked, it essentially sends a query string to a PHP script and then returns the relevant HTML, however, if I select a select it works fine if I then slect another checkbox as well as the previous I get no activity what so ever, not even any errors in firebug, it is very curious, does anyone have any ideas? //Location AJAX //var dataObject = new Object(); var selected = new Array(); //alert(selected); $('#areas input.radio').change(function(){ // will trigger when the checked status changes var checked = $(this).attr("checked"); // will return "checked" or false I think. // Do whatever request you like with the checked status if(checked == true) { //selected.join('&'); selected = $('input:checked').map(function() { return $(this).attr('name')+"="+$(this).val(); }).get(); getQuery = selected.join('&')+"&location_submit=Next"; alert(getQuery); $.ajax({ type:"POST", url:"/search/location", data: getQuery, success:function(data){ //alert(getQuery); //console.log(data); $('body.secEmp').html(data); } }); } else { //do something to remove the content here alert($(this).attr('name')); } });

  • Passing char * into fopen with C.

    - by Rhys
    Hey there, I'm writing a program that passes data from a file into an array, but I'm having trouble with fopen (). It seems to work fine when I hardcode the file path into the parameters (eg fopen ("data/1.dat", "r");) but when I pass it as a pointer, it returns NULL. Note that line 142 will print "data/1.dat" if entered from command line so parse_args () appears to be working. 132 int 133 main(int argc, char **argv) 134 { 135 FILE *in_file; 136 int *nextItem = (int *) malloc (sizeof (int)); 137 set_t *dictionary; 138 139 /* Parse Arguments */ 140 clo_t *iopts = parse_args(argc, argv); 141 142 printf ("INPUT FILE: %s.\n", iopts->input_file); /* This prints correct path */ 143 /* Initialise dictionary */ 144 dictionary = set_create (SET_INITAL_SIZE); 145 146 /* Use fscanf to read all data values into new set_t */ 147 if ((in_file = fopen (iopts->input_file, "r")) == NULL) 148 { 149 printf ("File not found...\n"); 150 return 0; 151 } Thanks!

  • Bind members of different classes

    - by 7vies
    In a C++ program I have two classes (structs) like struct A { int x; double y; // other members }; struct B { int x; double y2; // other members }; I'd like to somehow "bind" the corresponding members, e.g. A::x to B::x and A::y to B::y2. By "bind" I mean ability to obtain a reference to the bound variable, for example given a member of class A I could assign it to the value of the corresponding B member. Once I have such bind, I'd like to build a bind table or something similar which I could iterate over. This would allow, for example, copying the corresponding fields from A a; to B b; like CopyBound(a, b, bind_table);, but probably also doing some other things not limited to Copy interface. The problem with this bind_table is that I want static typing and the bind_table would have to contain different types in this case. For example, a table of pointers to class members would contain &A::x and &A::y, but they are of different type, so I cannot just put them say into an array. Any ideas how this can be conveniently implemented, having as much compile-time type checking as possible?

  • Wordpress and Anythingslider Navigation Thumbnails

    - by Tom
    So I am using AnythingSlider in Wordpress. This is why I am trying to call the thumbnails from the original posts. Anything slider will configure thumbnail navigation like this: function formatText(index, panel) { return index + ""; } $(function () { $('.anythingSlider').anythingSlider({ navigationFormatter: formatText // Details at the top of the file on this use (advanced use) }); }); As you can see, the navigationFormatter will allow me to format the nav (including thumbnails) however I want. For example, to format thumbnails, I could do this: navigationFormatter : function(i, panel){ // add thumbnails as navigation links return '<img src="images/th-slide-' + ['civil-1', 'env-1', 'civil-2', 'env-2'][i - 1] + '.jpg">'; } So my issue is getting the wordpress slide images to show up there dynamically, rather than in a folder (as the above example shows). For reference, this is my php query that is pulling the posts image (from a script I've already written: <img class="slider-img" style="float:left;" src="<?php if(function_exists('wp_get_post_image')){ echo wp_get_post_image(array( 'return_html' => false, 'width' => 500 )); } ?>" /> I hope this update helps. Thank you guys so much. The Stack overflow community is great!

  • Adding an observer to UIImageView? observer & notifications

    - by sagar
    Each class has almost one method named addObserver [imgVURL addObserver:<#(NSObject *)observer#> forKeyPath:<#(NSString *)keyPath#> options:<#(NSKeyValueObservingOptions)options#> context:<#(void *)context#>] Here, imgVURL is an image which is going to be load an image asynchronously. When image will be loaded dynamically - other class will set an image from loaded data. Now, my question is how can we add an observer to UIImageView's instance. Observer and notifications are same or not ? If it is not then what's different ? Let's have some sample code That I did in my project to understand my question. // locating image view from Scroll view by it's tag imgVURL=(UIImageView*)[scrMain viewWithTag:(kTagImagesTag+i)]; // ImageViewURL is a class which contains methods of // didReceiveResponse // didReceiveData // connection ImageViewURL *tmp=[[ImageViewURL alloc] init]; // it has a nonatomic property which will take the reference of my image view tmp.imgV=imgVURL; // now I will pass a url from my an array to property strURL // in strUrl I have custom setter // in which I am initializing a connection tmp.strUrl=[NSURL URLWithString:[[tblmain objectAtIndex:i] valueForKey:@"url"]]; // from ImageViewURL.m file -(void)connectionDidFinishLoading:(NSURLConnection *)connection { [[UIApplication sharedApplication] setNetworkActivityIndicatorVisible:NO]; // NSLog@"ImageView Ref From - %@",imgV); // see imgV has reference of my -> imgVURL (nonatomic,assign) imgV.image=[UIImage imageWithData:myWebData]; [connection release]; connection=nil; } // as you can see in above code many many images are loaded asynchronously // now How can I add an observer to an imageview whether it received or not.

  • Find unique vertices from a 'triangle-soup'

    - by sum1stolemyname
    I am building a CAD-file converter on top of two libraries (Opencascade and DWF Toolkit). However, my question is plattform agnostic: Given: I have generated a mesh as a list of triangular faces form a model constructed through my application. Each Triangle is defined through three vertexes, which consist of three floats (x, y & z coordinate). Since the triangles form a mesh, most of the vertices are shared by more then one triangle. Goal: I need to find the list of unique vertices, and to generate an array of faces consisting of tuples of three indices in this list. What i want to do is this: //step 1: build a list of unique vertices for each triangle for each vertex in triangle if not vertex in listOfVertices Add vertex to listOfVertices //step 2: build a list of faces for each triangle for each vertex in triangle Get Vertex Index From listOfvertices AddToMap(vertex Index, triangle) While I do have an implementation which does this, step1 (the generation of the list of unique vertices) is really slow in the order of O(n!), since each vertex is compared to all vertices already in the list. I thought "Hey, lets build a hashmap of my vertices' components using std::map, that ought to speed things up!", only to find that generating a unique key from three floating point values is not a trivial task. Here, the experts of stackoverflow come into play: I need some kind of hash-function which works on 3 floats, or any other function generating a unique value from a 3d-vertex position.

  • jQuery Autocomplete plugin (Jorn Zaefferer's) - how to dynamically change the list of displayed valu

    - by Max Williams
    I'm using Jorn Zaefferer's Autocomplete query plugin, http://bassistance.de/jquery-plugins/jquery-plugin-autocomplete/ I have options set so it shows all the values when you click in the empty text field, a bit like a select, and the option is also set so that the user can only choose from the list of values used by the autocomplete (so it's kind of like a select but with autocomplete functionality). I have two radio buttons below the text field, which determine whether the user chooses from a long list or a short list of possible values. I want to update the values used in the autocomplete when one of these radio buttons is clicked. Currently i'm doing this in a not very clever way by calling autocomplete again on the same text field, with the different array of values, but this creates a situation where both are active at once, and i can see the long list peeking out from behind the short list. What i need to do is either a) dynamically change the values used in the autocomplete or b) remove (unbind?) the autocomplete from the text field before re-initialising it. Either of these would do tbh though option a) is kind of nicer. Any ideas anyone? Here's my current code: function initSubjectLongShortList(field, short_values, long_values){ $(".subject_short_long_list").change(function(){ updateSubjectAutocomplete(field, short_values, long_values); }); updateSubjectAutocomplete(field, short_values, long_values); } function updateSubjectAutocomplete(field, short_values, long_values){ if($(".subject_short_long_list:checked").attr('id') == "subject_long_list"){ initSubjectAutocomplete(field, long_values); } else { initSubjectAutocomplete(field, short_values); } } function initSubjectAutocomplete(field, values){ jQuery(field).autocomplete(values, { minChars: 0, //make it appear as soon as we click in the field max: 2000, scrollHeight: 400, matchContains: true, selectFirst: false }); } cheers, max

  • Having Uploadify e-mail a link to download the file

    - by kwek-kwek
    Uploadify is a jQuery plugin that allows the easy integration of a multiple (or single) file uploads on your website. It requires Flash and any backend development language. An array of options allow for full customization for advanced users, but basic implementation is so easy that even coding novices can do it. I wanted to ask if It is possible to sends out a link of a file that has just been uploaded wioth the e-mail notification of Uploadify. Here is the code for uploadify.php : <?php if (!empty($_FILES)) { $tempFile = $_FILES['Filedata']['tmp_name']; $targetPath = $_SERVER['DOCUMENT_ROOT'] . $_REQUEST['folder'] . '/'; $targetFile = str_replace('//','/',$targetPath) . $_FILES['Filedata']['name']; // $fileTypes = str_replace('*.','',$_REQUEST['fileext']); // $fileTypes = str_replace(';','|',$fileTypes); // $typesArray = split('\|',$fileTypes); // $fileParts = pathinfo($_FILES['Filedata']['name']); // if (in_array($fileParts['extension'],$typesArray)) { // Uncomment the following line if you want to make the directory if it doesn't exist // mkdir(str_replace('//','/',$targetPath), 0755, true); move_uploaded_file($tempFile,$targetFile); echo "1"; // } else { // echo 'Invalid file type.'; // } } //define the receiver of the email $to = '[email protected]'; //define the subject of the email $subject = 'Test email'; //define the message to be sent. Each line should be separated with \n $message = "Hello World!\n\nThis is my first mail."; //define the headers we want passed. Note that they are separated with \r\n $headers = "From: [email protected]\r\nReply-To: [email protected]"; //send the email $mail_sent = @mail( $to, $subject, $message, $headers ); //if the message is sent successfully print "Mail sent".

  • SimpleXML - "Node no longer exists"

    - by SubZane
    Hi I'm trying to get the video data from this youtube playlist feed and add the interesting data to an array and use that later, but as you can see from the feed some videolinks are "dead" and that results in problems for my code. The error I get is "Node no longer exists" when I try to access $attrs['url']. I've tried for hours to find a way to check if the node exists before I access it but I have no luck. If anyone could help me to either parse the feed some other way with the same result or create a if-node-exists check that works I would be most happy. Thank you in advance $url = 'http://gdata.youtube.com/feeds/api/playlists/18A7E36C33EF4B5D?v=2'; $sxml = simplexml_load_file($url); $i = 0; $videoobj; foreach ($sxml->entry as $entry) { // get nodes in media: namespace for media information $media = $entry->children('http://search.yahoo.com/mrss/'); // get video player URL $attrs = $media->group->player->attributes(); $videoobj[$i]['url'] = $attrs['url']; // get video thumbnail $attrs = $media->group->thumbnail[0]->attributes(); $videoobj[$i]['thumb'] = $attrs['url']; $videoobj[$i]['title'] = $media->group->title; $i++; }

  • SVN: Release branch headaches, how to merge in website revisions as and when cleared to go live?

    - by Pete Duncanson
    I need a sanity check here if we can, any ideas on correcting/changing the following are very welcome! We've been getting ourselves in knots of late with our SVN and are trying to correct it by putting a Trunk/Release system in place. We have a large website that we develop on and we store it all in SVN. Heres what we had in mind: We have trunk and a release branch All work gets checked into Trunk. When a feature is deemed ready for the next release it is merged into a Release branch. We only have one release branch and just tag "Latest" when we do a push to live We hope to be able to get all the files changed from Latest to Head to give us a zip that we can upload (any ideas on an easy way to do this via scripting?) So we set all this up and where very happy with ourselves. Except its not working and heres why. We work on lots a different features/fixes/problems at once and they don't all get nicely checked in feature complete (but always working at least). Then sometimes you have to wait for Clients to sign off. As a result you end up with revisions which are "ready for live" being scattered with ones which are "still being worked on" in trunk. That means that the completed revisions are not getting merged in sequentially but out of order. I thought SVN could handle this, clever little thing it is, but apparently not. Heres an example: Pete changes some CSS to make a new button look pretty (Revision 1) Dave add some CSS to the bottom of the same CSS file as Pete's for a new feature (Revision 2) Dave's mod gets the nod so he merges it into Release and commits it with a log message mentioning revision number and bug tracking id. Pete adds more buttons to finish this mod, no CSS changes here though (Revision 3) Pete then merges his mods (Revision 1 and 3) into the Head of Release (which has Daves merge in it) but this over-writes Daves CSS additions which now dissapear completely. This leads to the site being broken and the Release branch being pretty much useless. So we tried some other ideas like reverting Release back to "Latest" and then just merging in all the Revisions 1,2 and 3 in order. This worked fine until we had Revision 4 which was not ready for live and Revision 5 which was. Suddenly we are getting ourselves in knots again with exactly the same problem! Ok so take three. Revert to Latest, merge in Revision 5, then do any update back to Head. Tree conflicts galore! So thats a no no. I cracked in the end and built it all up manaually but its not something I want to do regular, ideally I want to script our deployment but can't while Release is in such a mess. HELP! What the heck are we doing wrong? I can't seem to find any solutions to this problem of wanting different none sequential Revisions in Release. If its not possible thats fine but how the heck are we meant to get stuff live easily. We can't branch for every single change, the site takes 30 minutes+ to check out it would take too long. Side note, we are using TortoiseSVN so can we keep command line examples to a minimum in any answers? Latest version of TSVN and SVN Version 1.6 so we have the funky merge tracking etc. EDIT: An excellent blog post which deals with the dev/release cycle (although using GIT but still relivant) thought everyone would like to read it if they found this question interesting. (http://nvie.com/git-model) EDIT 2: I wrote a blog post on how to show which branch you are working on in your website which others have asked me about (http://www.offroadcode.com/2010/5/14/which-svn-branch-are-you-working-on.aspx). Hope that helps. In the meantime we are looking at Kiln and hoping to make the switch next month (gulp!)

    - by Lekensteyn
    I've been trying to get OpenVPN to work for three days. After reading many questions, the HOWTO, the FAQ and even parts of a guide to Linux networking, I cannot get my an Internet connection to the Internet. I'm trying to set up a OpenVPN server on a VPS, which will be used for: secure access to the Internet bypassing port restrictions (directadmin/2222 for example) an IPv6 connection (my client does only have IPv4 connectivity, while the VPS has both IPv4 and native IPv6 connectivity) (if possible) I can connect to my server and access the machine (HTTP), but Internet connectivity fails completely. I'm using ping 8.8.8.8 for testing whether my connection works or not. Using tcpdump and iptables -t nat -A POSTROUTING -j LOG, I can confirm that the packets reach my server. If I ping to 8.8.8.8 on the VPS, I get an echo-reply from 8.8.8.8 as expected. When pinging from the client, I do not get an echo-reply. The VPS has only one NIC: etho. It runs on Xen. Summary: I want to have a secure connection between my laptop and the Internet using OpenVPN. If that works, I want to have IPv6 connectivity as well. Network setup and software: Home laptop (eth0: 192.168.2.10) (tap0: 10.8.0.2) | | (running Kubuntu 10.10; OpenVPN 2.1.0-3ubuntu1) | wifi | router/gateway (gateway 192.168.2.1) | INTERNET | VPS (eth0:1.2.3.4) (gateway, tap0: 10.8.0.1) (running Debian 6; OpenVPN 2.1.3-2) wifi and my home router should not cause problems since all traffic goes encrypted over UDP port 1194. I've turned IP forwarding on: # echo 1 > /proc/sys/net/ipv4/ip_forward iptables has been configured to allow forwarding traffic as well: iptables -F FORWARD iptables -A FORWARD -m state --state RELATED,ESTABLISHED -j ACCEPT iptables -A FORWARD -s 10.8.0.0/24 -j ACCEPT iptables -A FORWARD -j DROP I've tried each of these rules separately without luck (flushing the chains before executing): iptables -t nat -A POSTROUTING -s 10.8.0.0/24 -o eth0 -j SNAT --to 1.2.3.4 iptables -t nat -A POSTROUTING -s 10.8.0.0/24 -o eth0 -j MASQUERADE route -n before (server): 1.2.3.4 0.0.0.0 255.255.255.0 U 0 0 0 eth0 0.0.0.0 1.2.3.4 0.0.0.0 UG 0 0 0 eth0 route -n after (server): 1.2.3.4 0.0.0.0 255.255.255.0 U 0 0 0 eth0 10.8.0.0 0.0.0.0 255.255.255.0 U 0 0 0 tap0 0.0.0.0 1.2.3.4 0.0.0.0 UG 0 0 0 eth0 route -n before (client): 192.168.2.0 0.0.0.0 255.255.255.0 U 2 0 0 wlan0 169.254.0.0 0.0.0.0 255.255.0.0 U 1000 0 0 wlan0 0.0.0.0 192.168.2.1 0.0.0.0 UG 0 0 0 wlan0 route -n after (client): 1.2.3.4 192.168.2.1 255.255.255.255 UGH 0 0 0 wlan0 10.8.0.0 0.0.0.0 255.255.255.0 U 0 0 0 tap0 192.168.2.0 0.0.0.0 255.255.255.0 U 2 0 0 wlan0 169.254.0.0 0.0.0.0 255.255.0.0 U 1000 0 0 wlan0 0.0.0.0 10.8.0.1 128.0.0.0 UG 0 0 0 tap0 128.0.0.0 10.8.0.1 128.0.0.0 UG 0 0 0 tap0 0.0.0.0 192.168.2.1 0.0.0.0 UG 0 0 0 wlan0 SERVER config proto udp dev tap ca ca.crt cert server.crt key server.key dh dh1024.pem server 10.8.0.0 255.255.255.0 push "redirect-gateway def1" ifconfig-pool-persist ipp.txt keepalive 10 120 tls-auth ta.key 0 comp-lzo user nobody group nobody persist-key persist-tun log-append openvpn-log verb 3 mute 10 CLIENT config dev tap proto udp remote 1.2.3.4 1194 resolv-retry infinite nobind persist-key persist-tun ca ca.crt cert client.crt key client.key ns-cert-type server tls-auth ta.key 1 comp-lzo verb 3 mute 20 traceroute 8.8.8.8 works as expected (similar output without OpenVPN activated): 1 10.8.0.1 (10.8.0.1) 24.276 ms 26.891 ms 29.454 ms 2 gw03.sbp.directvps.nl (178.21.112.1) 31.161 ms 31.890 ms 34.458 ms 3 ge0-v0652.cr0.nik-ams.nl.as8312.net (195.210.57.105) 35.353 ms 36.874 ms 38.403 ms 4 ge0-v3900.cr0.nik-ams.nl.as8312.net (195.210.57.53) 41.311 ms 41.561 ms 43.006 ms 5 * * * 6 209.85.248.88 (209.85.248.88) 147.061 ms 36.931 ms 28.063 ms 7 216.239.49.36 (216.239.49.36) 31.109 ms 33.292 ms 216.239.49.28 (216.239.49.28) 64.723 ms 8 209.85.255.130 (209.85.255.130) 49.350 ms 209.85.255.126 (209.85.255.126) 49.619 ms 209.85.255.122 (209.85.255.122) 52.416 ms 9 google-public-dns-a.google.com (8.8.8.8) 41.266 ms 44.054 ms 44.730 ms If you have any suggestions, please comment or answer.

  • Cocoa Touch UITableView Alphabetical '#' Match All Unmatched

    - by Kevin Sylvestre
    I have a UITableView containing names that I would like to group (and sort) by the first letter (similar to the Address Book application). I am currently able to match any section ('A'-'Z') using: // Sections is an array of strings "{search}" and "A" to "Z" and "#". NSString *pattern = [self.sections objectAtIndex:section]; NSPredicate *predicate = nil; // Ignore search pattern. if ([pattern isEqualToString:@"{search}"]) return nil; // Non-Alpha and Non-Diacritic-Alpha (?). if ([pattern isEqualToString:@"#"]); // Default case (use case and diacritic insensitivity). if (!predicate) predicate = [NSPredicate predicateWithFormat:@"name beginswith[cd] %@", pattern]; // Return filtered results. return [self.friends filteredArrayUsingPredicate:predicate]; However, matching for the '#' eludes me. I tried constructing a REGEX match using: [NSPredicate predicateWithFormat:@"name matches '[^a-zA-Z].*'"]; But this fails for diacritic-alpha (duplicate rows appear). Any ideas would be greatly appreciated! Thanks.

  • Looped jQuery slideshow with smooth cross-fades

    - by artlung
    I'm trying to do a simple rotating image on the home page. Under the hood I'm reading a directory and then populating urls for the images into an array. What I want to do is cross-fade the images. If it was just a matter of showing the next one, it's easy, but since I need to cross-fade, it's a bit harder. I think what I want to do is do the fades by calling animate() on the opacity value of the <img> tag, and in between swapping out the css background-image property of the enclosing <div>. But the results are not that great. I've used tools for more full featured slideshows, but I don't want the overhead of adding a plugin if I can avoid it, and a simple crossfade seems like it should be easier. Here's my JavaScript (I'm using jQuery 1.3.2): var slideshow_images = ["http:\/\/example.com\/wordpress\/wp-content\/themes\/testtheme\/sidebar-home-bg\/bg1.jpg","http:\/\/example.com\/wordpress\/wp-content\/themes\/testtheme\/sidebar-home-bg\/bg2.jpg","http:\/\/example.com\/wordpress\/wp-content\/themes\/testtheme\/sidebar-home-bg\/bg3.jpg"]; var slideshow_index = 0; var delay = 4000; var swapSlides = function() { var slideshow_count = slideshow_images.length; // initialize the background to be the current image $('#home-slideshow').css({ 'background-image': 'url(' + slideshow_images[slideshow_index] + ')', 'background-repeat:': 'no-repeat', 'width': 200, 'overflow': 'hidden' }); slideshow_index = ((slideshow_index + 1) == slideshow_count) ? 0 : slideshow_index + 1; // fade out the img $('#home-slideshow img').animate({opacity: 0}, delay); // now, the background is visible // next change the url on the img $('#home-slideshow img').attr('src', slideshow_images[slideshow_index]); // and fade it up $('#home-slideshow img').animate({opacity: 1.0}, delay); // do it again setTimeout('swapSlides()', 4000); } jQuery(document).ready(function(){ if (swapSlides) { swapSlides(); } }); And here's the markup I'm using: <div id="home-slideshow"><img src="http://example.com/wordpress/wp-content/themes/testtheme/sidebar-home-bg/bg1.jpg" alt="" /></div>

  • YUI DataTable - Howto have just one paginator?

    - by Rollo Tomazzi
    Hello, I'm using the YUI DataTable in a Grails 1.1 project using the Grails UI plugin 1.0.2 (YUI being 2.6.1). By default, the DataTable displays 2 paginators: one above and another one below the table. Looking up the YUI API documentation, I could see that I can pass an array of YUI containers as a config parameter but - what are the names of these containers? I've tried loooking at the HTML of the page using Firebug. The ID of the divs containing the paginators are: yui-dt0-paginator0 (above) and yui-dt0-paginator1 (below). If I use them to configure the containers for the navigator, then the navigator is just not displayed at all. Here's the relevant extract of the GSP page containing the Datatable element. <div class="body"> <h1>This is the List of Control Accounts</h1> <g:if test="${flash.message}"> <div class="message">${flash.message}</div> </g:if> <div class="yui-skin-sam"> <gui:dataTable controller="controlAccount" action="enhancedListDataTableJSON" columnDefs="[ [key:'id', label:'ID'], [key:'col1', label:'Col 1', sortable: true, resizeable: true], [key:'col2', label:'Col 2', sortable: true, resizeable: true] ]" sortedBy="col1" rowsPerPage="20" paginatorConfig="[ template:'{PreviousPageLink} {PageLinks} {NextPageLink} {CurrentPageReport}', pageReportTemplate:'{totalRecords} total accounts', alwaysVisible:true, containers:'yui-dt0-paginator1' ]" rowExpansion="true" /> </div> </div> Any help? Thanks! Rollo

  • Project Euler: Programmatic Optimization for Problem 7?

    - by bmucklow
    So I would call myself a fairly novice programmer as I focused mostly on hardware in my schooling and not a lot of Computer Science courses. So I solved Problem 7 of Project Euler: By listing the first six prime numbers: 2, 3, 5, 7, 11, and 13, we can see that the 6th prime is 13. What is the 10001st prime number? I managed to solve this without problem in Java, but when I ran my solution it took 8 and change seconds to run. I was wondering how this could be optimized from a programming standpoint, not a mathematical standpoint. Is the array looping and while statements the main things eating up processing time? And how could this be optimized? Again not looking for a fancy mathematical equation..there are plenty of those in the solution thread. SPOILER My solution is listed below. public class PrimeNumberList { private ArrayList<BigInteger> primesList = new ArrayList<BigInteger>(); public void fillList(int numberOfPrimes) { primesList.add(new BigInteger("2")); primesList.add(new BigInteger("3")); while (primesList.size() < numberOfPrimes){ getNextPrime(); } } private void getNextPrime() { BigInteger lastPrime = primesList.get(primesList.size()-1); BigInteger currentTestNumber = lastPrime; BigInteger modulusResult; boolean prime = false; while(!prime){ prime = true; currentTestNumber = currentTestNumber.add(new BigInteger("2")); for (BigInteger bi : primesList){ modulusResult = currentTestNumber.mod(bi); if (modulusResult.equals(BigInteger.ZERO)){ prime = false; break; } } if(prime){ primesList.add(currentTestNumber); } } } public BigInteger get(int primeTerm) { return primesList.get(primeTerm - 1); } }

  • Marshalling a big-endian byte collection into a struct in order to pull out values

    - by Pat
    There is an insightful question about reading a C/C++ data structure in C# from a byte array, but I cannot get the code to work for my collection of big-endian (network byte order) bytes. (EDIT: Note that my real struct has more than just one field.) Is there a way to marshal the bytes into a big-endian version of the structure and then pull out the values in the endianness of the framework (that of the host, which is usually little-endian)? This should summarize what I'm looking for (LE=LittleEndian, BE=BigEndian): void Main() { var leBytes = new byte[] {1, 0}; var beBytes = new byte[] {0, 1}; Foo fooLe = ByteArrayToStructure<Foo>(leBytes); Foo fooBe = ByteArrayToStructureBigEndian<Foo>(beBytes); Assert.AreEqual(fooLe, fooBe); } [StructLayout(LayoutKind.Explicit, Size=2)] public struct Foo { [FieldOffset(0)] public ushort firstUshort; } T ByteArrayToStructure<T>(byte[] bytes) where T: struct { GCHandle handle = GCHandle.Alloc(bytes, GCHandleType.Pinned); T stuff = (T)Marshal.PtrToStructure(handle.AddrOfPinnedObject(),typeof(T)); handle.Free(); return stuff; } T ByteArrayToStructureBigEndian<T>(byte[] bytes) where T: struct { ??? }

  • Can't send client certificate via SslStream

    - by Jonathan
    I am doing an SSL3 handshake using an SslStream, but, in spite of my best efforts, the SslStream never sends a client certificate on my behalf. Here is the code: SSLConnection = new System.Net.Security.SslStream(SSLInOutStream, false, new System.Net.Security.RemoteCertificateValidationCallback(AlwaysValidRemoteCertificate), new System.Net.Security.LocalCertificateSelectionCallback(ChooseLocalCertificate)); X509CertificateCollection CC = new X509CertificateCollection(); CC.Add(Org.BouncyCastle.Security.DotNetUtilities.ToX509Certificate(MyLocalCertificate)); SSLConnection.AuthenticateAsClient("test", CC, System.Security.Authentication.SslProtocols.Ssl3, false); and then I have AlwaysValidRemoteCertificate just returning true, and ChooseLocalCertificate returning the zeroth element of the array. The code probably looks a little weird because the project is a little weird, but I think that is beside the point here. The SSL handshake completes. The issue is that instead of sending a certificate message on my behalf (in the handshake process), with the ASN.1 encoded certificate (MyLocalCertificate), the SslStream sends an SSL alert number 41 (no certificate) and then carries on. I know this from packet sniffing. After the handshake is completed, the SslStream marks IsAuthenticated as true, IsMutuallyAuthenticated as false, and its LocalCertificate member is null. I feel like I'm probably missing something pretty obvious here, so any ideas would be appreciated. I am a novice with SSL, and this project is off the beaten path, so I am kind of at a loss. P.S. 1: My ChooseLocalCertificate routine is called twice during the handshake, and returns a valid (as far as I can tell), non-null certificate both times. P.S. 2: SSLInOutStream is my own class, not a NetworkStream. Like I said, though, the handshake proceeds mostly normally, so I doubt this is the culprit... but who knows?
