  • HTML relative links on various domains

    - by Adam Kiss
    I have quickie: When you code/develop themes, how do you link to various files in your html/css code? Example: We at our firm use mostly <base target="http://whatever"> in our main template and then just <img src="./images/file.png"> in our html, "/category/page" as links and something alike in our css. However, when testing on different machines, we use ip address rather than localhost on main dev station of coder, so all base links don't work (because localhost goes to viewing machine, not coder's, in our network). Same thing happens when updating pages - on dev server, we have to edit base target, so browsing site won't take us to live site - this part is actually rather simple PHP (if ... echo else echo something else), but it still not solve problem of more coding-testing problems. So, my question is, how do YOU solve it? How do you use relative links, which basically don't care for what domain is the page on and don't care for url rewrite? (because ../images/ is different for / and different for /something/somethingElse/page)?

  • Should conditional expressions go inside or outside of classes?

    - by Rupert
    It seems that often I will want to execute some methods from a Class when I call it and choosing which function will depend on some condition. This leads me to write classes like in Case 1 because it allows me to rapidly include their functionality. The alternative would be Case 2 which can take a lot of time if there is a lot of code and also means more code being written twice when I drop the Class into different pages. Having said that, Case 1 feels very wrong for some reason that I can't quite put my finger on. I haven't really seen any classes written like this, I suppose. Is there anything wrong with writing classes like in Case 1 or is Case 2 superior? Or is there a better way? What the advantages and disadvantages of each? Case 1 class Foo { public function __construct($bar) { if($bar = 'action1') $this->method1(); else if($bar = 'action2') $this->method2(); else $this->method1(); } public function method1() { } public function method2() { } } $bar = 'action1' $foo = new Foo($bar); Case 2 class Foo { public function __construct() { } public function method1() { } public function method2() { } } $foo = new Foo; $bar = 'action1'; if($bar == 'action1') $foo->method1(); else if($bar == 'action2') $foo->method2(); else $foo->method1();

  • Iphone - cannot grant permission for publishing on a Facebook page that i administer

    - by user323817
    I want to open a dialog on the IPhone so a user can grant my application permission to post on a Facebook page that the user administers. Following the docs, I can grant permissions for the user's stream and I can even post on a page that he is a fan of. However, the post on the page is listed as from the username, not on behalf of the page itself, even though he is an administrator of the page. According to the Prompting for Permissions section at: http://wiki.developers.facebook.com/index.php/Authorization_and_Authentication_for_Desktop_Applications I should be able to create a prompt on the IPhone for granting permission to publish_stream on a Facebook page that he administers. The sample url they give for a web "popup" dialog is: http://www.facebook.com/connect/prompt_permissions.php?api_key=YOURAPIKEY&v=1.0&next=http://www.facebook.com/connect/login_success.html?xxRESULTTOKENxx&display=popup&ext_perm=read_stream,publish_stream&enable_profile_selector=1&profile_selector_ids=1234%2C5454 This works as expected and a drop down of the pages is displayed. However, since my application is on the IPhone, I change the display=popup to display=touch. This does not seem to work and I've tried fiddling with the parameters several ways but the drop down never comes up. Anyone find a way around this? The popup option doesn't seem to work since I get an error trying to display it.

  • Python 3, urllib ... Reset Connection Possible?

    - by Rhys
    In the larger scale of my program the goal of the below code is to filter out all dynamic html in a web-page source code code snippet: try: deepreq3 = urllib.request.Request(deepurl3) deepreq3.add_header("User-Agent","etc......") deepdata3 = urllib.request.urlopen(deepurl3).read().decode("utf8", 'ignore') The following code is looped 3 times in order to identify whether the target web-page is Dynamic (source code is changed at intervals) or not. If the page IS dynamic, the above code loops another 15 times and attempts to filter out the dynamic content. QUESTION: While this filtering method works 80% of the time, some pages will reload ALL 15 times and STILL contain dynamic code. HOWEVER. If I manually close down the Python Shell and re-execute my program, the dynamic html that my 'refresh-page method' could not shake off is no longer there ... it's been replaced with new dynamic html that my 'refresh-page method' cannot shake off. So I need to know, what is going on here? How is re-running my program causing the dynamic content of a page to change. AND, is there any way, any 'reset connection' command I can use to recreate this ... without manually restarting my app. Thanks for your response.

  • ASP.NET MVC twitter/myspace style routing

    - by Astrofaes
    Hi guys, This is my first post after being a long-time lurker - so please be gentle :-) I have a website similar to twitter, in that people can sign up and choose a 'friendly url', so on my site they would have something like: mydomain.com/benjones I also have root level static pages such as: mydomain.com/about and of course my homepage: mydomain.com/ I'm new to ASP.NET MVC 2 (in fact I just started today) and I've set up the following routes to try and achieve the above. public static void RegisterRoutes(RouteCollection routes) { routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); routes.IgnoreRoute("content/{*pathInfo}"); routes.IgnoreRoute("images/{*pathInfo}"); routes.MapRoute("About", "about", new { controller = "Common", action = "About" } ); // User profile sits at root level so check for this before displaying the homepage routes.MapRoute("UserProfile", "{url}", new { controller = "User", action = "Profile", url = "" } ); routes.MapRoute("Home", "", new { controller = "Home", action = "Index", id = "" } ); } For the most part this works fine, however, my homepage is not being triggered! Essentially, when you browser to mydomain.com, it seems to trigger the User Profile route with an empty {url} parameter and so the homepage is never reached! Any ideas on how I can show the homepage?

  • asp.net mvc 2 - return JavaScript with View

    - by Tomaszewski
    Hi, using ASP.NET MVC 2 I have a navigation menu inside my Master Page. In the navigation menu, I am trying add a class to the that the current page relates to (i.e., home page will add class="active" to the Home button). I'm trying to consider scalability and the fact that I don't want to change individual pages if the navigation changes later. The only way I can think of doing this is: Add JavaScript to each individual View that will add the class when the DOM is ready Return JavaScript when return View() occurs on point (2), I am unsure how to do. Thusfar I have been doing the following in my controller: public ActionResult Index() { ViewData["messege"] = JavaScript("<script type='text/javascript' language='javascript'> $(document).ready(function () { console.log('hi hi hi'); }); </script>"); return View(); } but in my view, when I call: <%: ViewData["messege"] %> I get: System.Web.Mvc.JavaScriptResult as the result Would you guys have any ideas on How to solve the navigation menu probelem, other than the solutions I've listed return JavaScript along with your view from the Controller Thanks, in advanced!

  • "Finding" an object instance of a known class?

    - by Sean C
    My first post here (anywhere for that matter!), re. Cocoa/Obj-C (I'm NOT up to speed on either, please be patient!). I hope I haven't missed the answer already, I did try to find it. I'm an old-school procedural dog (haven't done any programming since the mid 80's, so I probably just can't even learn new tricks), but OOP has my head spinning! My question is: is there any means at all to "discover/find/identify" an instance of an object of a known class, given that some OTHER unknown process instantiated it? eg. somthing that would accomplish this scenario: (id) anObj = [someTarget getMostRecentInstanceOf:[aKnownClass class]]; for that matter, "getAnyInstance" or "getAllInstances" might do the trick too. Background: I'm trying to write a plugin for a commercial application, so much of the heavy lifting is being done by the app, behind the scenes. I have the SDK & header files, I know what class the object is, and what method I need to call (it has only instance methods), I just can't identify the object for targetting. I've spent untold hours and days going over Apples documentation, tutorials and lots of example/sample code on the web (including here at Stack Overflow), and come up empty. Seems that everything requires a known target object to work, and I just don't have one. Since I may not be expressing my problem as clearly as needed, I've put up a web page, with diagram & working sample pages to illustrate: http://www.nulltime.com/svtest/index.html Any help or guidance will be appreciated! Thanks.

  • Is a control's OnInit called even when attaching it during parent's OnPreRender?

    - by Xerion
    My original understanding was that the asp.net page lifecycle is run once for all pages and controls under normal circumstances. When I attached a control during a container's OnPreRender, I encountered a situation where the control's OnInit was not called. OK, I considered that a bug in my code and fixed as such, by attaching the control earlier. But just today, I encountered a situation where OnInit for a control seems to be called after the normal OnInit has been done for everyone else. See stack below. It seems that during the page's PreRender, the control's OnInit is called as it is being dynamically added. So I just want to confirm exactly what ASP.NET's behavior is? Does it actually keep track of the stage of each control's lifecycle, and upon adding a new control, it will run from the very beginning? [HttpException (0x80004005): The control collection cannot be modified during DataBind, Init, Load, PreRender or Unload phases.] System.Web.UI.ControlCollection.Add(Control child) +8678663 MyCompany.Web.Controls.SetStartPageWrapper.Initialize() MyCompany.Web.Controls.SetStartPageWrapper.OnInit(EventArgs e) System.Web.UI.Control.InitRecursive(Control namingContainer) +333 System.Web.UI.Control.InitRecursive(Control namingContainer) +210 System.Web.UI.Control.AddedControl(Control control, Int32 index) +198 System.Web.UI.ControlCollection.Add(Control child) +80 MyCompany.Web.Controls.PageHeader.OnPreRender(EventArgs e) in System.Web.UI.Control.PreRenderRecursiveInternal() +80 System.Web.UI.Control.PreRenderRecursiveInternal() +171 System.Web.UI.Control.PreRenderRecursiveInternal() +171 System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +842

  • Can't make HREF change based on PHP value

    - by Liso22
    I want to retrieve the user's location and then show a link that points to an URL that changes according to that location. I just want to place the user's city name at the end of the HREF. I need this work on my wordpress site, on a static page. I use a plugin called Exec-php which let's me run PHP in pages. I have a plugin that provides me the user's city through the shortcode "[mmjs-city]". I tried to make it work through different paths but I never get the link to work. Here I tried assigning that shortcode to a value, <?php $city= "[mmjs-city]"; echo $city; echo "<a href='?s=" . $city ."'>Search for your city</a>"; ?> I added the first two lines to check whether the shortcode is working or not and if it's correctly assinged to the value $city. That part works. Then it creates the link and put's the value $city at the end of it. But when trying it instead of taking me to: /?s=new+york It takes me to: /?s=%3Cscript%20language=%22javascript%22%3Edocument.write(geoip_city());%3C/script%3E I have no idea what to do. I would be really thankful for any info on how to make it work, it's really an important feature for my site. Please ask for any further info or idk anything. Also this is where I tested that code: http://chusmix.com/?page_id=1129 Thanks

  • Linking how PHP/HTML

    - by Azzyh
    Hello. Alright so im done doing pages with frames, and know i splitted up my design to top.php and bottom.php. In top.php it's linking to style.css and ajax_framework.js and such.. Now this works great until i tried to include top.php & bottom.php in videos/index.php (another dirr), i did like this: include "../top.php"; <-- and the originally index.php --> include "../bottom.php"; Now when i enter the site, it wont load style.css, probably because it thinks that style.css needs to be in videos/ directory, same goes with ajax_framework.js that are both files are on the parent ../ directory. Now what do i do? Some method or technique to solve this in a good way? So i dont have to copy style.css and ajax_framework.js into every directory i have, because then later if i want to change something i would need to change in all directories, which would be my last thing i want to do.. hope you got some nice techniques thank you

  • SIlverlight Navigate: how does it work? How would you implement in f# w/o VS wizards and helpers?

    - by akaphenom
    After a nights sleep the problem can be stated more accurately as I have a 100% f# / silverlight implementation and am looking to use the built in Navigation components. C# creates page.xaml and page.xaml.cs um - ok; but what is the relationship at a fundamental level? How would I go about doing this in f#? The applcuation is loaded in the default module, and I pull the XAML in and reference it from the application object. Do I need to create instances / references to the pages from within the application object? Or set up some other page management object with the proper name value pairs? When all the Help of VS is stripped away - what are we left with? original post (for those who may be reading replies) I have a 100% silverlight 3.0 / f# 2.0 application I am wrapping my brain around. I have the base application loading correctly - and now I want to add the naigation controls to it. My page is stored as an embedded resource - but the Frame.Navigate takes a URI. I know what I have is wrong but here it is: let nav : Frame = mainGrid ? mainFrame let url = "/page1.xaml" let uri = new System.Uri(url, System.UriKind.Relative) ; nav.Navigate uri Any thoughts?

  • drupal hook_menu_alter9) for adding tabs

    - by EricP
    I want to add some tabs in the "node/%/edit" page from my module called "cssswitch". When I click "Rebuild Menus", the two new tabs are displayed, but they are displayed for ALL nodes when editing them, not just for the node "cssswitch". I want these new tabs to be displayed only when editing node of type "cssswitch". The other problem is when I clear all cache, the tabs completely dissapear from all edit pages. Below is the code I wrote. function cssswitch_menu_alter(&$items) { $node = menu_get_object(); //print_r($node); //echo $node->type; //exit(); if ($node->type == 'cssswitch') { $items['node/%/edit/schedulenew'] = array( 'title' => 'Schedule1', 'access callback'=>'user_access', 'access arguments'=>array('view cssswitch'), 'page callback' => 'cssswitch_schedule', 'page arguments' => array(1), 'type' => MENU_LOCAL_TASK, 'weight'=>4, ); $items['node/%/edit/schedulenew2'] = array( 'title' => 'Schedule2', 'access callback'=>'user_access', 'access arguments'=>array('view cssswitch'), 'page callback' => 'cssswitch_test2', 'page arguments' => array(1), 'type' => MENU_LOCAL_TASK, 'weight'=>3, ); } } function cssswitch_test(){ return 'test'; } function cssswitch_test2(){ return 'test2'; } Thanks for any help.

  • How to direct link to an attribute set?

    - by monocat
    I have created attributes; “Shop by Type” and “Shop by Color”. They work great within the layered navigation and extended search. I’ve designed graphics and placed them in the home page and would like to link to the respective attribute’s assigned products. Been searching the webs, but so far have been unsuccessful. If there’s no direct possible way, the next method would be creating cms pages and linking to it directly. How can I display products that are assigned to a specific attribute? Specifically “Multiple Select” types. I know you guys prefer at least some attempts, but as mentioned, been playing with it with no luck. I would appreciate some kind of starting point. Happy Holidays! Edit: I was able to put together this code that lists all the products assigned to said category id. Tried to filter it down where it only displays products that have an assigned same attribute with no luck yet. Any ideas? <?php $cat_id = 123; // category id $category = Mage::getModel('catalog/category')->load($cat_id); $_products = $category->getProductCollection() ->addAttributeToSelect('shop_by_color'); if (($this->getProductCollection()) && $_products->getSize()): ?> By the way, $cat_id is a sub category of root. Is there an easier way to point to it instead of using direct id number?

  • RewriteRule to store thousands of files in subdirectories

    - by Brandon
    I have a website that will have millions of pages in a directory. I'd like to store those files on-disk in a bunch of subdirectories based on the first characters of the page name. For example http://mysite.com/hugedir/somefile.html would be stored in /var/www/html/hugedir/s/o/m/e/f/ile.html That is fairly trivial to do with a RewriteRule like so: RewriteRule ^hugedir/(.)(.)(.)(.)(.)(.*).html /hugedir/{$1}/{$2}/{$3}/{$4}/{$5}/$6.html RewriteRule ^hugedir/(.)(.)(.)(.)(.*).html /hugedir/{$1}/{$2}/{$3}/{$4}/{$5}.html RewriteRule ^hugedir/(.)(.)(.)(.*).html /hugedir/{$1}/{$2}/{$3}/{$4}.html RewriteRule ^hugedir/(.)(.)(.*).html /hugedir/{$1}/{$2}/{$3}.html RewriteRule ^hugedir/(.)(.*).html /hugedir/{$1}/{$2}.html RewriteRule ^hugedir/(.*).html /hugedir/{$1}.html However, the file name may contain hyphens or other non-standard characters and I'd really like to avoid having a directory named with a strange character. Ideally, I'd like to have a list of 'approved' characters and either eliminate or transform the unapproved characters to an underscore. Can anybody think of a way to do that? Or something else equivalent? Part of the requirement is that these be physical files on disk and it not be parsed with a scripting language.

  • PHP - dynamic page via subdomain

    - by Phil Jackson
    Hi, im creating profile pages based on a subdomains using the wildcard DNS setting. Problem being, if the subdomain is incorrect, I want it to redirect to the same page but without the subdomain infront ie; if ( preg_match('/^(www\.)?([^.]+)\.domainname\.co.uk$/', $_SERVER['HTTP_HOST'], $match)) { $DISPLAY_NAME = $match[2]; $query = "SELECT * FROM `" . ACCOUNT_TABLE . "` WHERE DISPLAY_NAME = '$DISPLAY_NAME' AND ACCOUNT_TYPE = 'premium_account'"; $q = mysql_query( $query, $CON ) or die( "_error_" . mysql_error() ); if( mysql_num_rows( $q ) != 0 ) { }else{ mysql_close( $CON ); header("location: http://www.domainname.co.uk"); exit; } } I get a browser error: Firefox has detected that the server is redirecting the request for this address in a way that will never complete. I think its because when using header("location: http://www.domainname.co.uk"); it still puts the sub domain infront i.e. ; header("location: http://www.sub.domainname.co.uk"); Does anyone know how to sort this and/or what is the problem. Regards, Phil

  • Loading dynamic external content into the Div of another on click

    - by Robin I Knight
    Trying to load an external php file into another onClick. Iframes will not work as the size of the content changes with collapsible panels. That leaves AJAX. I was given a piece of code HTML <a href="#" id="getData">Get data</a> <div id="myContainer"></div> JS $('#getData').click(function(){ $.get('data.php', { section: 'mySection' }, function(data){ $('#myContainer').html(data); }); }); PHP: <?php if($_GET['section'] === 'mySection') echo '<span style="font-weigth:bold;">Hello World</span>'; ?> I have tested it here http://www.divethegap.com/scuba-diving-programmes-dive-the-gap/programme-pages/dahab-divemaster/divemaster-trainingA.php and get the most unexpected results. It certainly loads the right amount of items as it says in the lower bar on safari but I see three small calendars and that is it. Can anyone see where I have made a mistake?

  • MVC Html.ActionLink with post funtionality?

    - by Levitikon
    I'm checking to see if anyone has written an MVC extension for Html.ActionLink that you can pass in Post parameters like such: <% Html.ActionLink("Click me", "Index", "Home", new { MyRouteValue = "123" }, null, new { postParam1 = "a", postParam2 = "b" }); %> That would render the link like normal but having an onClick event that submits an also rendered form with an Action url for the Action, Controller, and Route Values with additional hidden inputs from the Post Parameters like such: <a href="#" onClick="$('#theform').submit(); return false;">Click me</a> <form id="theform" action="/Home/Index/123" method="post"> <input type="hidden" name="postParam1" value="a"> <input type="hidden" name="postParam2" value="b"> </form> I'm looking to redirect users to various pages with potentially a lot of data. Not only from page to page, but from email to page also. This would be highly reusable and I think would clean up a lot of code, and would save a bunch of time writing this if its already floating around out there. I hate recreating the wheel when I don't have to. Thanks!

  • How to use RewriteBase in .htaccess to rewrite img tags?

    - by Eileen
    I guess I don't understand RewriteBase. I have a (drupal) site built on my dev server and everything works perfectly. I created a fake URL for it in my own apache and hosts file, so I get to my local version with "local-examplesite.com". Eventually it will live at www.examplesite.com, but I want to put up a draft with a temp URL at my hosting company like so: 123.45.67.89/~examplesite . I set the RewriteBase in .htaccess to /~examplesite . All the pages work fine, and all the navigation links go to the right places. But none of my images work! They are of the format src="/sites/default/images/blah.png", and so the tags are getting rendered as src="http://123.45.67.89/sites/default/images/blah.png", instead of src="http://123.45.67.89/~examplesite/sites/default/images/blah.png". Is there any way I can get the site to point to right images? I thought that's what rewritebase was for, but after reading up a bit I guess it is for URLs only (the ones that get rewritten, natch).

  • What's the best way to "shuffle" a table of database records?

    - by Darth
    Say that I have a table with a bunch of records, which I want to randomly present to users. I also want users to be able to paginate back and forth, so I have to perserve some sort of order, at least for a while. The application is basically only AJAX and it uses cache for already visited pages, so even if I always served random results, when the user tries to go back, he will get the previous page, because it will load from the local cache. The problem is, that if I return only random results, there might be some duplicates. Each page contains 6 results, so to prevent this, I'd have to do something like WHERE id NOT IN (1,2,3,4 ...) where I'd put all the previously loaded IDs. Huge downside of that solution is that it won't be possible to cache anything on the server side, as every user will request different data. Alternate solution might be to create another column for ordering the records, and shuffle it every insert time unit here. The problem here is, I'd need to set random number out of a sequence to every record in the table, which would take as many queries as there are records. I'm using Rails and MySQL if that's of any relevance.

  • Exclude subdirectory from rewrite rule in web.config

    This question comes up often, but I can only find solutions for PHP, Apache, htaccess etc but not for web.config I would like my pages to return in HTTP not HTTPS, except for forms within certain subdirectories. I have created the following web.config file, but how do I exclude a subdirectory called forms. <configuration> <system.webServer> <rewrite> <rules> <rule name="Force all to HTTP" stopProcessing="true"> <match url="(.*)" /> <conditions> <add input="{HTTPS}" pattern="on" ignoreCase="true" /> </conditions> <action type="Redirect" redirectType="Found" url="http://www.mysite.com/{R:1}" /> </rule> </rules> </rewrite> </system.webServer> </configuration> Many thanks all you clever clogs.

  • TypeError when using v 0.8.1 of FLOT library, but no error with v. 0.7

    - by DanielAttard
    I need some help to figure out why I am getting an error when trying to create a simple graph using the jQuery FLOT library. When I reference version 0.7 of the FLOT library, the page renders correctly: http://attardpropertytax.ca/flot07.html But when I switch to version 0.8.1 of the FLOT library, the page returns an error saying: Uncaught TypeError: Cannot read property 'left' of null http://attardpropertytax.ca/flot81.html The HTML is the same for both pages, so I cannot figure out why the new version 0.8.1 of FLOT returns an error, but the old version 0.7 does not. Any ideas? I somehow stumbled across a work-around that managed to fix my problem. I'm nut sure why, but I had to comment-out the following two sections of code from the v. 0.8.1 FLOT library: This was the first spot: // If the grid is visible, add its border width to the offset for (var a in plotOffset) { if(typeof(options.grid.borderWidth) == "object") { plotOffset[a] += showGrid ? options.grid.borderWidth[a] : 0; } else { plotOffset[a] += showGrid ? options.grid.borderWidth : 0; } } And this was the second spot: if (isNaN(v) || v < axis.min || v > axis.max // skip those lying on the axes if we got a border || (t == "full" && ((typeof bw == "object" && bw[axis.position] > 0) || bw > 0) && (v == axis.min || v == axis.max))) continue; I'm sure eventually @DNS will be taking a look at this question and maybe he will be able to help me understand what is going wrong with my code. Thanks.

  • Website. VoteUp or VoteDown Videos. How to restrict users voting multiple times?

    - by DJDonaL3000
    Im working on a website (html,css,javascript, ajax, php,mysql), and I want to restrict the number of times a particular user votes for a particular video. Its similar to the YouTube system where you can voteUp or voteDown a particular video. Each vote involves adding a row to the video.votes table, which logs the time, vote direction(up or down), the client IPaddress( using PHP: $ip = $_SERVER['REMOTE_ADDR']; ), and of course the ID of the video in question. Adding votes is as simple as; (pseudocode): Javascript:onClick( vote( a,b,c,d ) ), which passes variables to PHP insertion script via ajax, and finally we replace the voteing buttons with a "Thank You For Voting" message. THE PROBLEM: If you reload/refresh the page after voting, you can vote again, and again, and again, you get the point. MY QUESTION: How do you limit the amount of times a particular user votes for a particular video?? MY THOUGHTS: Do you use cookies, and add a new cookie with the id of the video. And check for a cookie before you insert a new vote.? OR Before you insert the vote, do you use the IPaddress and the videoID to see if this same user(IP) has voted for this same video(vidID) in the past 24hrs(mktime), and either allow or dissallow the voteInsertion based on this query? OR Do you just not care? Take the assumption that most users are sane, and have better things to do than refresh pages and vote repeatedly.?? Any suggestions or ideas welcome.

  • System Calls in windows & Native API?

    - by claws
    Recently I've been using lot of Assembly language in *NIX operating systems. I was wondering about the windows domain. Calling convention in linux: mov $SYS_Call_NUM, %eax mov $param1 , %ebx mov $param2 , %ecx int $0x80 Thats it. That is how we should make a system call in linux. Reference of all system calls in linux: Regarding which $SYS_Call_NUM & which parameters we can use this reference : http://docs.cs.up.ac.za/programming/asm/derick_tut/syscalls.html OFFICIAL Reference : http://kernel.org/doc/man-pages/online/dir_section_2.html Calling convention in Windows: ??? Reference of all system calls in Windows: ??? Unofficial : http://www.metasploit.com/users/opcode/syscalls.html , but how do I use these in assembly unless I know the calling convention. OFFICIAL : ??? If you say, they didn't documented it. Then how is one going to write libc for windows without knowing system calls? How is one gonna do Windows Assembly programming? Atleast in the driver programming one needs to know these. right? Now, whats up with the so called Native API? Is Native API & System calls for windows both are different terms referring to same thing? In order to confirm I compared these from two UNOFFICIAL Sources System Calls: http://www.metasploit.com/users/opcode/syscalls.html Native API: http://undocumented.ntinternals.net/aindex.html My observations: All system calls are beginning with letters Nt where as Native API is consisting of lot of functions which are not beginning with letters Nt. System Call of windows are subset of Native API. System calls are just part of Native API. Can any one confirm this and explain.

  • Kohana Auth Library Deployment

    - by Steve
    My Kohana app runs perfectly on my local machine. When I deployed my app to a server (and adjust the config files appropriately), I can no longer log into the app. I've traced through the app login routine on both my local version and the server version and they both agree with each other all the way through until you get to the auth.php controller logged_in() routine where suddenly, at line 140 - the is_object($this-user) test - the $user object no longer exists!?!?!? The login() function call that calls the logged_in() function successfully passes the following test, which causes a redirect to the logged_in() function. if(Auth::instance()->login($user, $post['password'])) Yes, the password and hash, etc all work perfectly. Here is the offending code: public function logged_in() { if ( ! is_object($this->user)) { // No user is currently logged in url::redirect('auth/login'); } etc... } As the code is the same between my local installation and the server, I reckon it must be some server setting that is messing with me. FYI: All the rest of the code works because I have a temporary backdoor available that allows me to use the application (view pages of tables, etc) without being logged in. Any ideas?
