  • Registry remotley hacked win 7 need help tracking the perp

    - by user577229
    I was writing some .VBS code at thhe office that would allow certain file extensions to be downloaded without a warning dialog on a w7x32 system. The system I was writing this on is in a lab on a segmented subnet. All web access is via a proxy server. The only means of accessing my machine is via the internet or from within the labs MSFT AD domain. While writing and testing my code I found a message of sorts. Upon refresing the registry to verify my code changed a dword, instead the message HELLO was written and visible in regedit where the dword value wass called for. I took a screen shot and proceeded to edit my code. This same weird behavior occurred last time I was writing registry code except on another internal server. I understand that remote registry access exists for windows systems. I will block this immediately once I return to the office. What I want to know is, can I trace who made this connection? How would I do this? I suspect the cause of this is the cause of other "odd" behaviors I'm experiencing at work such as losing control of my input director master control for over an hour and unchanged code that all of a sudden fails for no logical region. These failures occur at funny times, whenver I'm about to give a demonstration of my test code. I know this sounds crazy however knowledge of the registry component makes this believable. Once the registry can be accessed, the entire system is compromised. Any help or sanity checking is appreciated.

  • Help getting MVVM ViewModel to bind to the View

    - by cw
    Okay guys, I'm new to this model and Silverlight in general. I have the following code (changed object names, so syntax/spelling errors ignore). public class ViewModel { ViewModelSource m_vSource; public ViewModel(IViewModelSource source) { m_vSource= source; m_vSource.ItemArrived += new Action<Item>(m_vSource_ItemArrived); } void m_vSource_ItemArrived(Item obj) { Title = obj.Title; Subitems = obj.items; Description = obj.Description; } public void GetFeed(string serviceUrl) { m_vFeedSource.GetFeed(serviceUrl); } public string Title { get; set; } public IEnumerable<Subitems> Subitems { get; set; } public string Description { get; set; } } Here is the code I have in my page's codebehind. ViewModel m_vViewModel; public MainPage() { InitializeComponent(); m_vViewModel = new ViewModel(new ViewModelSource()); this.Loaded += new RoutedEventHandler(MainPage_Loaded); this.DataContext = m_vViewModel; } void MainPage_Loaded(object sender, RoutedEventArgs e) { m_vViewModel.GetItems("http://www.myserviceurl.com"); } Finally, here is a sample of what my xaml looks like. <!--TitleGrid is the name of the application and page title--> <Grid x:Name="TitleGrid" Grid.Row="0"> <TextBlock Text="My Super Title" x:Name="textBlockPageTitle" Style="{StaticResource PhoneTextPageTitle1Style}"/> <TextBlock Text="{Binding Path=Title}" x:Name="textBlockListTitle" Style="{StaticResource PhoneTextPageTitle2Style}"/> </Grid> I know I'm missing something, but I'm just not knowledgable enough which is why I'm asking you guys :) Is there anything I'm doing wrong here? Thanks!

  • Python/YACC: Resolving a shift/reduce conflict

    - by Rosarch
    I'm using PLY. Here is one of my states from parser.out: state 3 (5) course_data -> course . (6) course_data -> course . course_list_tail (3) or_phrase -> course . OR_CONJ COURSE_NUMBER (7) course_list_tail -> . , COURSE_NUMBER (8) course_list_tail -> . , COURSE_NUMBER course_list_tail ! shift/reduce conflict for OR_CONJ resolved as shift $end reduce using rule 5 (course_data -> course .) OR_CONJ shift and go to state 7 , shift and go to state 8 ! OR_CONJ [ reduce using rule 5 (course_data -> course .) ] course_list_tail shift and go to state 9 I want to resolve this as: if OR_CONJ is followed by COURSE_NUMBER: shift and go to state 7 else: reduce using rule 5 (course_data -> course .) How can I fix my parser file to reflect this? Do I need to handle a syntax error by backtracking and trying a different rule?

  • Using "ocamlfind" to make the OCaml compiler and toplevel find (project specific) libraries

    - by CharlieP
    Hello, I'm trying to use ocamlfind with both the OCaml compiler and toplevel. From what I understood, I need to place the required libraries in the _tags file at the root of my project, so that the ocamlfind tool will take care of loading them - allowing me to open them in my modules like so : open Sdl open Sdlvideo open Str Currently, my _tags file looks like this : <*>: pkg_sdl,pkg_str I can apparently launch the ocamlfind command with the ocamlc or ocamlopt argument, provided I wan't to compile my project, but I did not see an option to launch the toplevel in the same manner. Is there any way to do this (something like "ocamlfind ocaml")? I also don't know how to place my project specific modules in the _tags file : imagine I have a module name Land. I am currently using the #use "land.ml" directive to open the file and load the module, but it has been suggested that this is not good practice. What syntax should I use in _tags to specify it should be loaded by ocamlfind (considering land.ml is not in the ocamlfind search path) ? Thank you, Charlie P. Edit : According to the first answer of this post, the _tags file is not to be used with ocamlfind. The questions above still stand, there is just a new one to the list : what is the correct way to specify the libraries to ocamlfind ?

  • Does Internet Explorer 7 have a CSS parsing issue with the "background-image" property?

    - by user312003
    Having CSS layout issues with Internet Explorer 7 (big surprise). Upon using the Developer Tools to inspect the CSS, I discovered that some properties defined in the stylesheet are not appearing in the parsed CSS structure... THEN I saw THIS being shown as the parsed value for the background-image property: background-image : url(/trunk/httpdocs/images/layout/HCBL_Homepage_01.jpg); WIDTH: 1200px; pretty much obliterating the width that was defined property. The actual code in the CSS file for this element: div#header { width: 1200px; height: 100px; margin-left: auto; margin-right: auto; background-image: url('/trunk/httpdocs/images/layout/HCBL_Homepage_01.jpg'); background-repeat: no-repeat; } If anyone could offer any insight, or provide a link describing this problem (and maybe a workaround...) I would be very appreciative. Also, I am only interested in this from a parsing of the stylesheet and CSS syntax perspective. I am not concerned with rendering and display issues at the moment; I simply want to get IE 7 (and I have a feeling IE 6 will have similar issues) to recognize and parse ALL of the CSS properties that have been defined in the stylesheet. Thanks in advance guys!

  • Creating a form dynamically

    - by Nathan
    Hi, I use a search button that creates a form dynamically at the server side and returns it with Jquery syntax. After I fill-up the form and click on submit button, there is another .submit() Jquery function that suppose to be called to validate input before data is sent to the server. But, for some reason, this function is never called, and the data is request is sent. In more details: This is the form that the serach button creates dynamically at the server side and "prints" to html page with Jquery: <form action=... name="stockbuyform" class="stockbuyform" method="post"> <input type=text value="Insert purchasing amount"> <input type="submit" value="Click to purchase"> </form> And here is the .submit() function : $(".stockbuyform").submit(function() { alert("Need to validate purchasing details"); } But whaen I click on purchase button, the .submit() function is never called. Does it mean that I can't use another Jquery call with the answer I got in the first call?

  • jQuery/Javascript: Click event on a checkbox and the 'checked' attribute.

    - by b. e. hollenbeck
    The code: $('input.media-checkbox').live('click', function(e){ e.preventDefault(); var that = $(this); if (that.attr('checked') == 'checked'){ var m = that.attr('media'); var mid = 'verify_' + m; that.parents('div.state-container').find('ul.' + mid).remove(); that.attr('checked', false); } else { var url = AJAX_URL; $.ajax({ type: 'GET', url: url, dataType: 'html', success: function(data){ that.parents('li').siblings('li.verification').children('div.media-verification').append(data).fadeIn(500); that.attr('checked', 'checked'); } }); } return false; }); I am ajaxing in a form, then firing the click event on relevant checkboxes to ajax in another partial if necessary. The form is inserted nicely, and the click events are fired, checking the boxes that need to be checked and firing the second ajax, since the checked attribute of the checkbox was initially false. What's curdling my cheese is if I UNCHECK one of those boxes. Despite e.preventDefault(), the checked attribute is set to false BEFORE the test, so the if statement always executes the else statement. I've also tried this with $.is(':checked'), so I'm completely baffled. It appears that unchecked - checked state reads the original state, but checked - unchecked doesn't. Any help?

  • Can I specify the files to commit in subversion in a file rather than on the command line?

    - by René Nyffenegger
    I have renamed (with svn move) a lot of files in a subversion project. Now, I am trying to commit these on Window's cmd.exe. It seems that I hit a limit (probably by cmd.exe) in that the number of files is too long for the command line to swallow. Now, I thought and hoped that I could list the files to commit in a seperate file that I could specify with the commit command (something like svn ci --files-to-commit=renamed-files.txt -m "Renamed a lot of files" Yet, either such an option does not exist or I am unable to find this. Unfortunately, I cannot do a svn ci . as I have done other changes in the project as well. Neither can I do a svn ci *pattern-of-renamed-files* since this would only check in the added files, not the deleted ones. Before I start checking in the files with smaller chunks of files to check in (and thus increase the revision number uneccesserily without giving a hint as to the 'atomicity' of the operation) I thought I ask if this is indeed impossible to do.

  • Extract attributes from NSManagedObject array.

    - by Pavel Peroutka
    NSFetchRequest *req = [NSFetchRequest init]; NSEntityDescription *descr = [NSEntityDescription entityForName:@"City" inManagedObjectContext:context]; [req setEntity:descr]; NSSortDescriptor *sort = [[NSSortDescriptor alloc] initWithKey:@"streetName" ascending:YES]; [req setSortDescriptors:[NSArray arrayWithObject:sort]]; [sort release]; //fetch NSError *error; NSArray *result = [context executeFetchRequest:req error:&error]; //extract names NSMutableArray *streets = [[NSMutableArray alloc] init]; for () { ??? = [array objectAtIndex:i]; [streets addObject:name]; } I expected Core Data to be little more intuitive. I am new in it and I could use some help. I fetched all objects(rows) from the entity (table) City. Now I have an array of objects. From the array I need to extract the attribute “streetName” to an array which will feed the picker. I figured I need to do it in the loop but I could not figure out the way to do it. Please help. I have a background with SQL but Core Data is still a big mystery to me. Is there any publication which would take a SQL statement and show comparable Core Data syntax? Thanks.

  • bind event handler on keydown listen function JavaScript jQuery

    - by user1644123
    I am trying to bind a handler to an event. The event is a keydown function. The handler will listen for hit variables to produce one of two conditions. The 1st condition (odd number of hits) will perform 1 function, the 2nd (even number of hits) will perform another function. To elaborate, the 1st function will scroll to one element, the 2nd will scroll to another element. My syntax may be the wrong approach, but it works for the 1st condition, but not the 2nd. I think I have the conditional statement in the wrong place. How can I rewrite this to work as intended? Thank you kindly, in advance! $(document).keydown(function(e) { switch (e.which) { case 37: break; case 38: break; case 39: break; case 40: //bottom arrow key var hits = 0; if (hits % 2 !== 0) { $('#wrap').animate({ scrollTop: $("#scrollToHere").offset().top }, 2800); } else { $('#wrap').animate({ scrollTop: $("#scroll2ToHere").offset().top }, 2800); } hits++; return false; break; } })? *I moved "var hits = 0;" to the top, but it only works! But is there a way I can reset the whole thing after every two hits? I want to reset because when there is a bug and if I press a 3rd time it scrolls to the very top of the page, where there is no element to make it scroll to the top. Why would it scroll to the top of the page if I never scripted it to do so?? *

  • Has form post behavior changed in modern browsers? (or How are double clicks handled by the browser)

    - by Alex Czarto
    Background: We are in the process of writing a registration/payment page, and our philosophy was to code all validation and error checking on the server side first, and then add client side validation as a second step (un-obstructive jQuery). We wanted to disable double clicks server side, so we wrote some locking, thread-safe code to handle simultaneous posts/race conditions. When we tried to test this, we realized that we could not cause a simultaneous post or race condition to occur. I thought that (in older browsers anyway) double clicking a submit button worked as follows: User double clicks submit button. Browser sends a post on the first click On the second click, browser cancels/ignores initial post, and initiates a second post (before the first post has returned with a response). Browser waits for second post to return, ignoring initial post response. I thought that from the server side it looked like this: Server gets two simultaneous post requests, executes and responds to them both (unaware that no one is listening to the first response). From our testing (FireFox 3.0, IE 8.0) this is what actually happens: User double clicks submit button Browser sends a post for the first click Browser queues up second click, but waits for the response from the first click. Response returns from first click (response is ignored?). Browser sends a post for the second click. So from a server side: Server receives a single post which it executes and responds to. Then, server receives a second request wich it executes and responds to. My question is, has this always worked this way (and I'm losing my mind)? Or is this a new feature in modern browsers that prevents simultaneous posts to be sent to the server? It seems that for server side double click prevention, we don't have to worry about simultaneous posts or race conditions. Only need to worry about queued up posts. Thanks in advance for any feedback / comments. Alex

  • Java (or possibly other languages) learning path

    - by bgo
    I am familiar (as a self-learner) with C, python and php such that i can solve some problems involving simple steps (for example, i easily do calculations for physics lab reports with python which normally would take 4x-5x times longer with a calculator). The point here is, as doing such things, i learnt the idea / concepts of programming language and problem solving along with oop or fuctional programming etc. Recently i have started Java and, with the familiarity of other languages, i am doing well for starters but i need guidence. -I am thinking of learning syntax from sun java tutorials and then practicing with codingbat.com or similar sites. I need a reference book that i can study deeper aspects of the topics i am learning. What do you suggest about these? -The problem is (and always have been) the lack of practice. I need coding and problem-solving practices sources. I stuck at the point where i can't figure out what to do next. Can you suggest any source (possibly like codingbat)? If i could plan a learning trail, i can progress faster and efficiently. So i need ideas, comments, suggestions. Thanks in advance.

  • Scrolling to the bottom of a div on page load: issue with syntaxhighlighter

    - by Rayne
    I've been using this code: var objDiv = document.getElementById("code"); objDiv.scrollTop = objDiv.scrollHeight; to scroll to the very bottom of the div. It worked perfectly in FF and Chrome (I asked a question about it not working in Chrome a few days ago, but it appears the guy who was testing it on Chrome was incorrect, so I tested it myself) until I started syntax highlighting the code that I put in the div with SyntaxHighlighter. Before, I was putting the code in a <p> and breaking lines with <br />, but the <br /> stuff doesn't fly with SyntaxHighlighter, so I replaced all of those with newlines (not entirely certain if this is important, but it's worth mentioning). Now, when the page loads, it does scroll, but not all the way down. It scrolls nearly to the bottom. I've tried all the methods listed in the other question I mentioned but they all do the same thing, or nothing at all. Is there anything else I can try? Here is the relevant piece of the generated HTML. Forgive the poor formatting, I'm not writing the HTML by hand, but rather using Hiccup with Clojure, and it doesn't bother with formatting. <div class="scroll" id="code"><pre class="brush: clojure">=> (doseq [x (range 1 100)] (println x)) 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 nil </pre></div><script type="text/javascript">var objDiv = document.getElementById("code"); objDiv.scrollTop = objDiv.scrollHeight;</script>

  • Can any linux API or tool watch for any change in any folder below e.g. /SharedRoot or do I have to

    - by Simon B.
    I have a folder with ~10 000 subfolders. Can any linux API or tool watch for any change in any folder below e.g. /SharedRoot or do I have to setup inotify for each folder? (i.e. I loose if I want to do this for 10k+ folders). I guess yes, since I've already seen examples of this inefficient method, for instance http://twistedmatrix.com/trac/browser/trunk/twisted/internet/inotify.py?rev=28866#L345 My problem: I need to keep folders time-sorted with most recently active "project" up top. When a file changes, each folder above that file should update its last-modified timestamp to match the file. Delays are ok. Opening a file (typically MS Excel) and closing again, its file date can jump up and then down again. For this reason I need to wait until after a file is closed, then queue the folder of that file for checking, and only a while later do I go and look for the newest file in its folder, since the filedate of the triggering file could already be back-dated to its original timestamp by Excel or similar programs. Also in case several files from same folder are used/created, it makes sense to buffer timestamping of that folders' parents to at least get a bunch of updates collapsed into one delayed update. I'm looking for a linux solution. I have some code that can be run on a windows server, most of the queing functionality is here: http://github.com/sesam/FolderdateFollowsFiles/blob/master/FolderdateFollowsFiles/Follower.vb Available API:s The relative of inotify on windows, ReadDirectoryChangesW, can watch a folder and its whole subtree; see bWatchSubtree on http://msdn.microsoft.com/en-us/library/aa365465(VS.85).aspx Samba? Patching samba source is a possibility, but perhaps there are already hooks available? Other possibilities, like client side (various windows versions) and spying on file activities in order to update folders recursively?

  • Any high-level languages that can use c libraries?

    - by Isaiah
    I know this question could be in vain, but it's just out of curiosity, and I'm still much a newb^^ Anyways I've been loving python for some time while learning it. My problem is obviously speed issues. I'd like to get into indie game creation, and for the short future, 2d and pygame will work. But I'd eventually like to branch into the 3d area, and python is really too slow to make anything 3d and professional. So I'm wondering if there has ever been work to create a high-level language able to import and use c libraries? I've looked at Genie and it seems to be able to use certain libraries, but I'm not sure to what extent. Will I be able to use it for openGL programing, or in a c game engine? I do know some lisp and enjoy it a lot, but there aren't a great many libraries out there for it. Which leads to the problem: I can't stand C syntax, but C has libraries galore that I could need! And game engines like irrlicht. Is there any language that can be used in place of C around C? Thanks so much guys

  • asp.net 4.0 webforms - how to keep ContentPlaceHolder1_ out of client id's in a simple way?

    - by James Manning
    I'm attempting to introduce master pages to an existing webforms site that's avoided using them because of client id mangling in the past (and me not wanting to deal with the mangling and doing <% foo.ClientID % everywhere :) GOAL: use 'static' id values (whatever is in the server control's id attribute) except for data-bound / repeating controls which would break for those cases and therefore need suffixes or whatever to differentiate (basically, Predictable) Now that the site migrated to ASP.NET 4.0, I first attempted to use ClientIDMode of Static (in the web.config) but that broke too many places doing repeating controls (checkboxes inside gridviews, for instance) since they all resulted with the same id. So, I then tried Predictable (again, just in the web.config) so that the repeating controls wouldn't have conflicting id's, and it works well except that the master page content placeholder (which is indeed a naming container) is still reflecting in the resulting client id's (for instance, ContentPlaceHolder1_someCheckbox). Certainly I could leave the web.config setting as static and then go through all the databound/repeating controls switch them to Predictable, but I'm hoping there's some easier/simpler way to get that effect without having to scatter ClientIDMode attributes in those N number of places (or extend all those databound controls with my own usercontrol that just sets clientidmode, or whatever). I even thought of leaving web.config set to static and doing a master or basepage handler (preinit? not sure if that would work or not) that would go walk Controls with OfType<INamingContainer() (might be a better choice on the type, but that seems like a good starting choice looking at repeater and gridview) and then set those to Predictable so I'd get static for all my 'normal' things outside of repeating controls but not have to deal with static inside things like gridview/repeater/etc. I don't see any way to mark the content placeholder such that it 'opts out' of being included in child id's - setting the ID of the placeholder to empty/blank doesn't work as it's a required attribute :) At that point I figured there was a better/simpler way that I was missing and decided to ask on SO :) Edit: I thought about changing all my 'fetch by id' jquery calls from $('#foo') to fetch_by_id('foo') and then having that function return the 'right one' by checking $('#foo').length and then $('#ContentPlaceHolder1_foo').length (and maybe other patterns) or even just have it return $('#foo, #ContentPlaceHolder1_foo') (again, potentially other patterns) but changing all the places I fetch elements by id seemed pretty ugly too, and I'd like to avoid that abstraction layer if possible to do so easily :)

  • Help making userscript work in chrome

    - by Vishal Shah
    I've written a userscript for Gmail Pimp.my.Gmail & i'd like it to be compatible with Google Chrome too. Now i have tried a couple of things, to the best of my Javascript knowledge (which is very weak) & have been successful up-to a certain extent, though im not sure if it's the right way. Here's what i tried, to make it work in Chrome: The very first thing i found is that contentWindow.document doesn't work in chrome, so i tried contentDocument, which works. BUT i noticed one thing, checking the console messages in Firefox and Chrome, i saw that the script gets executed multiple times in Firefox whereas in Chrome it just executes once! So i had to abandon the window.addEventListener('load', init, false); line and replace it with window.setTimeout(init, 5000); and i'm not sure if this is a good idea. The other thing i tried is keeping the window.addEventListener('load', init, false); line and using window.setTimeout(init, 1000); inside init() in case the canvasframe is not found. So please do lemme know what would be the best way to make this script cross-browser compatible. Oh and im all ears for making this script better/efficient code wise (which is sure there is)

  • Creating an SQL variable character column > 255 characters supporting multiple databases

    - by Piers
    I have an application that stores data through an ODBC data source of the user's choosing. So far it has worked well on a range of database systems (e.g. JET, Oracle, SQL Server), as the SQL syntax is fairly simple. Now I am running into a problem where I need to store more than 255 characters in my strings. Previously I created the table using column type VARCHAR (255). Now if I try to create a table using, e.g. VARCHAR (512) then it falls over on Access databases. I know that I can use the MEMO type for Access, but this is non-standard SQL and will thus likely fail on other database systems (e.g. Oracle). Is there any widely supported SQL standard for creating text columns wider than 255 characters, or do I need to find another solution? The alternatives seem to me to be: 1) Profile the database system and customise the SQL CREATE TABLE command based on the database system. I don't like this as it defeats the purpose of using ODBC. 2) Add extra columns of 255 chars as required (e.g. LONGSTRING1, LONGSTRING2, ...) and concatenate after reading. I don't like this because it means the number of columns can vary between tables and it complicates read/write. Are there any other viable alternatives to these two options? Or is it possible to have an SQL compliant CREATE TABLE command supported by the majority of database vendors, that supports strings longer than 255 chars?

  • Running an executable on network share with CustomAction with wix?

    - by martin
    Hello, i have created a msi-package which compresses some xml-files to a zip-file during installation. I have created a CustomAction for this purposes: <CustomAction Id="CompressMy" BinaryKey="zipEXE" ExeCommand="a -tzip &quot;[TEMPLATE_DIR]my.zip&quot; &quot;[TempSourceFolder]data.xml&quot;" Return="check" HideTarget="no" Impersonate="no" Execute="deferred" /> The installation works fine, if i try to install to a local drive, but recently a customer wanted to install [TEMPLATE_DIR] to a network drive on Windows Vista. The CustomAction fails, because of the elevated install-user hasn't mapped the network drive, even if the installer-calling user has mapped the drive. This happens also, if I try to install to an unc-path. I use 7zip for compressing. I have added it to my msi-package. I have tried to set Impersonate="yes", but then the Installations fails, if my TEMPLATE_DIR is f.e. the ProgramData-dir. Do you have any idea what i can do? I thinked about checking if TEMPLATE_DIR is a network path, but I didn't know how i can check this. Or do you have any other Ideas how I can provide a local and a network installation while using this custom action. Would be great if there are any advices, greetings, Martin

  • [iphone,twitter] Accessing the Twitter API through a proxy using NSURLConnectionsm, OAuth problem

    - by akaii
    I'm having no problems with sending an update directly via hxxps://api.twitter.com/, but the app (for the Iphone, I'm using NSURLConnections) I'm working is supposed to allow the user to select a preferred proxy (e.g. hxxps://twitter-proxy.appspot.com/api/ or hxxps://nest.onedd.net/api/), and I keep getting a 401 error (Failed to validate oauth signature and token) whenever I try to get an access token via these proxies. Even though I send my POST request to the proxy, I am still using the direct url for the api (https:// api.twitter.com/[rest api path]) in the base string. Despite the 401 error message above, the status code I'm actually getting from connection:didReceiveResponse: is 200, probably because it was able to successfully contact the proxy... Is there anything else that I need to consider when using a proxy to access the API? Should anything in the authorization header change, for example? Or the base string? I can manage to connect via Basic Auth without issue, but support for that will be dropped in a month. On a somewhat unrelated note... What are the possible causes of Twitter's error 403, and how do you distinguish between them? Is the only way to differentiate an error due to exceeding the status update limit for an hour (150 per hour) vs for a day (1000 per day) by checking the string reply returned in the response? Is there any way for me to simulate a status update limit error without going through the motions of actually sending 150/1000 tweets?

  • Zend_Form using subforms getValues() problem

    - by wiseguydigital
    Hi all, I am building a form in Zend Framework 1.9 using subforms as well as Zend_JQuery being enabled on those forms. The form itself is fine and all the error checking etc is working as normal. But the issue I am having is that when I'm trying to retrieve the values in my controller, I'm receiving just the form entry for the last subform e.g. My master form class (abbreviated for speed): Master_Form extends Zend_Form { public function init() { ZendX_JQuery::enableForm($this); $this->setAction('actioninhere') ... ->setAttrib('id', 'mainForm') $sub_one = new Form_One(); $sub_one->setDecorators(... in here I add the jQuery as per the docs); $this->addSubForm($sub_one, 'form-one'); $sub_two = new Form_Two(); $sub_two->setDecorators(... in here I add the jQuery as per the docs); $this->addSubForm($sub_two, 'form-two'); } } So that all works as it should in the display and when I submit without filling in the required values, the correct errors are returned. However, in my controller I have this: class My_Controller extends Zend_Controller_Action { public function createAction() { $request = $this->getRequest(); $form = new Master_Form(); if ($request->isPost()) { if ($form->isValid($request->getPost()) { // This is where I am having the problems print_r($form->getValues()); } } } } When I submit this and it gets past isValid(), the $form-getValues() is only returning the elements from the second subform, not the entire form.

  • Ideas for jumping in 2D with Actionscript 3 [included attempt]

    - by befall
    So, I'm working on the basics of Actionscript 3; making games and such. I designed a little space where everything is based on location of boundaries, using pixel-by-pixel movement, etc. So far, my guy can push a box around, and stops when running into the border, or when try to the push the box when it's against the border. So, next, I wanted to make it so when I bumped into the other box, it shot forward; a small jump sideways. I attempted to use this (foolishly) at first: // When right and left borders collide. if( (box1.x + box1.width/2) == (box2.x - box2.width/2) ) { // Nine times through for (var a:int = 1; a < 10; a++) { // Adds 1, 2, 3, 4, 5, 4, 3, 2, 1. if (a <= 5) { box2.x += a; } else { box2.x += a - (a - 5)*2 } } } Though, using this in the function I had for the movement (constantly checking for keys up, etc) does this all at once. Where should I start going about a frame-by-frame movement like that? Further more, it's not actually frames in the scene, just in the movement. This is a massive pile of garbage, I apologize, but any help would be appreciated.

  • Is this an example for parametric polymorphism?

    - by mrt181
    Hi i am educating myself oop principles. I would like to know if this is a correct example of Cardellis definition of parametric polymorphism. Please enlighten me. The example is in cfml's script based syntax. <cfcomponent> <cfscript> public numeric function getlength(any arg, string type){ switch (arguments.type){ case "array": return arraylen(arguments.arg); break; case "struct": return structcount(arguments.arg); break; case "string": return len(arguments.arg); break; case "numeric": return len(arguments.arg); break; case "object": // gets the number of parent classes, substracting the railo base class return -1 + arraylen(structfindkey(getmetadata(arguments.arg),"extends","all")); break; default: // throw was added to railo as a user defined function to use it in cfscript throw("InvalidTypeArgument","The provided type argument is invalid for method getlength"); } } </cfscript> </cfcomponent>
