• [Android] How do I load URL that requires login into variable?

  - by bebeTech

  I am trying to port my usage meter from a JavaScript Gadget (win) / Widget (OSX) to Android. Total newbie when comes to JAVA + Eclipse + Android 2.1 SDK. Essentially what I want to do is load a page, pass through a username and password and load the resulting page into a array that I can then run some regular expressions through. My code from JavaScript (I've replace the actual URL with a dummy one) is: xmlhttp.open("post","https://acme.com.au/your_account/index.php?function=login",false); xmlhttp.setRequestHeader("If-Modified-Since", "Sat, 1 Jan 2000 00:00:00 GMT"); xmlhttp.setRequestHeader("Content-Type", "application/x-www-form-urlencoded"); xmlhttp.send("check_username=" + username + "&password=" + password); I need to know the Android equivalent to the above please. I've played around with WebView but that loads the page in a web browser which isn't what I want.

• Memory leak till crash due to HttpRequest

  - by Alex R.

  I played with HttpRequest and realized that the memory is not cleaned up after any request. After some time the running tab within Chrome will crash. Here is some testing code. Put a large sized file into the 'www' directory and set the URL in the code accordingly. import 'dart:async'; import 'dart:html'; void main() { const PATH = "http://127.0.0.1:3030/PATH_TO_FILE"; new Timer.periodic(new Duration(seconds:10), (Timer it)=>getString(PATH)); } void getString( String url){ HttpRequest.getString(url).then((String data){ }); } Is this really a bug or did I something wrong?

  - by Erik Larsson

  I'm new to cookies, and im trying to set a cookie where to store the referrer (the org ref). But when i try this function: function do_it_cookie() { // Check if cookie exists if (isset($_COOKIE['ref'])) { // It dose exist, do nothing or anything... } else { setcookie ('ref', $_SERVER['HTTP_REFERER'], time() + 60, '/'); header ("Location: http://www.nyttforetag.com/mind-your-own-business/"); } } I want to store the cookie on the user computer for 30 days, if the return i want to know the initial refereeing url.

• Freeing JavaScript object

  - by pion

  I am looking at the example from http://www.javascriptkit.com/javatutors/oopjs.shtml var person = new Object() person.name = "Tim Scarfe" person.height = "6Ft" But there is no mention how to "free" it in order to avoid memory leak. Will the following code free it? person = null; How do you free a JavaScript Object using "new Object()? How do you free a JavaScript Array allocated using "new Array(10)"? How do you free a JavaScript JSON allocated using "var json = {"width": 480, "height": 640}"? Thanks in advance for your help.

• how to "lock" live site when doing (phing) deployment

  - by Jorre

  On http://www.slideshare.net/eljefe/automated-deployment-with-phing in slide 15 they are talking about "locking the live site" when doing deployment. We are running multiple webshops in a SAAS application where it is possible that users are adding products, buying products and paying for products online, and so on... When deploying we want to do this as clean as possible, so that not payments or orders or other critical data will be lost. We have a deployment scenario set up using phing (amazing tool!) but we are missing one crucial step being the "locking of the live site" while deploying. What is a possible way to lock a live site and bring it back online after deploying?

• Some input regarding Dojo (smooth css change on mouseover)

  - by Andy Walpole

  I've been playing around with Dojo over the last couple of days. The script below changes the background position of the list item when the mouse is over the link. dojo.query('a[class=main-menu-link]').forEach(function(linkTwo) { dojo.connect(linkTwo, "onmouseover", function(evt) { dojo.query('#main-menu ul li').forEach(function(linkThree) { dojo.style(linkThree, { "backgroundPosition": "right center", }); }); You can see it in action in the right hand side menu: http://www.mechanic-one.suburban-glory.com/ I'm trying to work out the best of way of giving it a smooth transition between the two states... I've been looking on the Dojo documentation page but I'm not sure what is the best way of approaching it.

• How do you leave comments/like a specific page of a Facebook Canvas app?

  - by Sebastian

  I'm building a tabbed Facebook Canvas app that requires individual images to be "Like"d and commented on. Since each image is loaded up as its own page, in this style: http://apps.facebook.com/appname/image/333/ (which translates to: www.mydomain.com/image/333/) I was hoping I could just get a UID for each "image" page and then comment/like based off that. If that's possible, how exactly do I get the id for dynamically generated pages? Or any page for that matter? Thanks in advance.

• Giving Users an Option Between UDP & TCP?

  - by cam

  After studying TCP/UDP difference all week, I just can't decide which to use. I have to send a large amount of constant sensor data, while at the same time sending important data that can't be lost. This made a perfect split for me to use both, then I read a paper (http://www.isoc.org/INET97/proceedings/F3/F3_1.HTM) that says using both causes packet/performance loss in the other. Is there any issue presented if I allow the user to choose which protocol to use (if I program both server side) instead of choosing myself? Are there any disadvantages to this? The only other solution I came up with is to use UDP, and if there seems to be too great of loss of packets, switch to TCP (client-side).

• Universal App won't build for device

  - by Felix Khazin

  I'm trying to get an iPad/iPhone app to run on my iPad. (it builds and runs fine on the simulator) I went through the menu to create a new universal project. Then I added another library that my app will use (route-me), and i keep getting the following linker errors: "___restore_vfp_d8_d15_regs", referenced from: and "___save_vfp_d8_d15_regs", referenced from: I did a search on Google, and found (http://www.badrit.com/blog/2010/6/6/building-route-me-for-ipad) that it's just a matter of matching up project settings in the library projects. I did that but it didn't help. I still keep getting these linker errors. Anyone have any ideas what I can try?

• Why can't I use relative URLs with IE7?

  - by gomezuk

  Hello everyone. I've been Googling for a while and can't seem to find an answer to this question. My problem is as follows: For my jquery, I need my links to be relative rather than absolute. My PHP is set to return relative urls and everything is working fine, until I test it in IE7. For some reason, IE7 keeps changing my relative urls to abosulute, which breaks my js script. Is this normal? Is there a way to get around it? For example: IE8, Chrome, Firefox, Safari etc - <a href='/page' onclick='click_handler(this);return false;'>clicky</a> IE7 - <a href='http://www.myurl.com/page' onclick='click_handler(this);return false;'>clicky</a>

• Is there a way to make this perl code capture stderr as well as stdout from a tcsh?

  - by mikelong

  open UNIT_TESTER, qq(tcsh -c "gpath $dir/$tsttgt; bin/rununittests"|); while(<UNIT_TESTER>){ reportError($ignore{testabort},$tsttgt,"test problem detected for $tsttgt:$_ ") if /core dumped/; reportError($ignore{testabort},$tsttgt,"test problem detected for $tsttgt:$_ ") if /\[ FAILED \]/; writelog($tsttgt,$_); } close UNIT_TESTER; I have tried to redirect stderr to stdout using this syntax but it didn't work: open UNIT_TESTER, qq(tcsh -c "gpath $dir/$tsttgt; bin/rununittests >& "|); I have also read the discussion on the perl FAQ but that was in relation to bash: http://www.perl.com/doc/FAQs/FAQ/oldfaq-html/Q5.15.html

• Unexpected htaccess behaviour (mod_rewrite and apache)

  - by avastreg

  Yeah, mod_rewrite is driving me crazy. Here is the problem: my htaccess RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^(.*)$ index.php?url=$1 [L,QSA] when i try to access the page advantix (so address was www.mywebsite.com/advantix), i'm being redirected to advantix/?url=advantix Looking at the access log, i have a suspicious 301 in the middle "GET /advantix HTTP/1.1" 301 335 "-" "Mozilla/5.0" "GET /advantix/?url=advantix HTTP/1.1" 200 186 "-" "Mozilla/5.0" There is one important detail: advantix is a directory. So, if i comment that rule, advantix goes to the folder and list the files. Why it applies automatically the / if there's a folder matching? I don't want to reach the folder, i want to reach index.php?url=advantix with a call to advantix. I have the rewriteLogs too, but they didn't help more. My vhost conf has Directory tag with Options All, if helps, i don't know much about that.

• Google says: Sort parameters in URL problematic

  - by feklee

  From Google's recommendations for URL structure: Sorting parameters. Some large shopping sites provide multiple ways to sort the same items, resulting in a much greater number of URLs. For example: http://www.example.com/results?search_type=search_videos&search_query=tpb&search_sort=relevance&search_category=25" When linking from outside, then having URLs differing only by sort parameters is obviously a bad idea: Google will not understand that these links point to the same item, i.e. that the item is popular. Therefore ranking will be lower than it should. But what's the alternative? Using a fragment identifier (#), and then doing the sorting in JavaScript? What else? Some settings in Webmaster tools?

• Should a service layer return view models for an MVC application?

  - by erg39

  Say you have an ASP.NET MVC project and are using a service layer, such as in this contact manager tutorial on the asp.net site: http://www.asp.net/mvc/tutorials/iteration-4-make-the-application-loosely-coupled-cs If you have viewmodels for your views, is the service layer the appropriate place to provide each viewmodel? For instance, in the service layer code sample there is a method public IEnumerable<Contact> ListContacts() { return _repository.ListContacts(); } If instead you wanted a IEnumerable, should it go in the service layer, or is there somewhere else that is the "correct" place? Perhaps more appropriately, if you have a separate viewmodel for each view associated with ContactController, should ContactManagerService have a separate method to return each viewmodel?

• parsing xml attribute value

  I have been parsing xml content using the xmlreader and cannot use the xml document but so far it works getting all elementcontent except for the attribute contents.

• The implicit function __strcpy_chk() call

  - by Summer_More_More_Tea

  Hi everyone: I'm now performing a stack buffer overflow attack test on my own PC( Ubuntu 9.10, gcc-4.4.1 ) based on the article http://www.tenouk.com/Bufferoverflowc/Bufferoverflow4.html. Yet I haven't achieved the goal. Each time a segfault is thrown accompanied with some error informaiton. I compile the source code, and wanna get further information using objdump. Function __strcpy_chk is invoked in the assembly code dumped out, and it's said that "The __strcpy_chk() function is not in the source standard; it is only in the binary standard." Does this the mechanism a compiler employed to protect runtime stack? To finish my test, how can I bypass the protection? Regards.

• POST Ajax call results in not found using jqGrid and ASP.NET MVC 2 on IIS6

  - by Dan

  This is puzzling me. I deployed an MVC 2 application to IIS6 and everything works fine except for my jqGrid calls to get data. All is well on my development machine, but here are the two URLs I'm working with Local dev web server: POST http://localhost:port/Ctrl.mvc/JsonMethod IIS6 (notice https - not sure if that matters) POST https://www.domain.com/AppName/Ctrl.mvc/JsonMethod The latter URL results in a HTTP 404, which is really confusing as all works well on my local machine. The JsonMethod is properly declared with [AcceptVerbs(HttpVerbs.Post)] Let me know if any more info is needed - I appreciate any and all help with this!

• AS3 / Java - Socket Connection from live Flash to local java

  - by PitchBlackCat

  Hey guys, I'm trying to get a live flash that lives on a webserver to talk to a local java server, that will live on the clients PC. I'm trying to achieve this with a socket connection. (port 6000) Now, at first flash was able to connect, but it just sends <policy-file-request/>. After this nothing happens. Now, some people at Kirupa suggested to send an cross-domain-policy xml as soon as any connection is established from the java side. http://www.kirupa.com/forum/showthread.php?t=301625 However, my java server just throws the following: End Exception: java.net.SocketException: Software caused connection abort: recv failed I've already spend a great amount of time on this subject, and was wondering if anyone here knows what to do?

• jQuery code to track clicks on outgoing links (google analystics)

  - by Tristan

  Hello, I found this on the web: $('a[href^=http]:not("[href*=://' + document.domain + ']")').click(function() { pageTracker._trackPageview('/outgoing/' + $(this).attr('href')); }); But it's not working. In my Google Analytics account there are no /outgoing/ links showing (it's been 24+ hours since I implemented it). What's wrong with this code? I'm using jQuery of course ;) (PS : i already have : <script type="text/javascript"> var gaJsHost = (("https:" == document.location.protocol) ? "https://ssl." : "http://www."); document.write(unescape("%3Cscript src='" + gaJsHost + "google-analytics.com/ga.js' type='text/javascript'%3E%3C/script%3E")); </script> <script type="text/javascript"> try { var pageTracker = _gat._getTracker("UA MY CODE"); pageTracker._trackPageview(); } catch(err) {}</script>)
