    - by Kabumbus
    I can and would love to use boost or std for this. Sorry - I am new to C++.

How to add such event listner and event function to my class?

  • Input array is longer than the number of columns in this table

    - by Adam
    I've recently started to use SQLite and began to integrate it into a C# project I'm working on. However, randomly my project will throw the exception: Input array is longer than the number of columns in this table I'm having a hard time trying the trace the problem because it seems to be thrown on a random basis. DataTable table = new DataTable(); //exception is thrown here table = Global.db.ExecuteQuery("SELECT * FROM vm_manager"); Some of the data that gets returned from this query is as follows: http://i.imgur.com/9rlLN.png If anyone has any advice, I'd be grateful. EDIT: I'm unable to show the execute query function as it resides inside a dll from the following sql lite wrapper http://www.codeproject.com/KB/database/cs_sqlitewrapper.aspx

  • Best way to deal with session handling in Zend Framework

    - by JACK IN THE CRACK
    So I'm starting up in Zend framework and looking to implement a site-wide "User" session.... something I can easily access from ALL modules/controllers in the application. I'm like, should I make a new namespace in the library and extend the controller, like: MyLib_Controller_Action extends Zend_Controller_Action { protected $_userSession; function preDispatch(Zend_Controller_Request_Abstract $req) { $this->_userSession = new Zend_Session_Namespace('user'); } } ANd then have all my controllers/modules/etc extend from that? Or should I create a Plugin or what? How would you go about making this plugin to pass the user session to the controller? Or do I do it in the bootstrap?? Again how to pass to controller? Also should I use Zend_Session_Namespace or Zend_Http_Cookie and also how do I encrypt and xss clean the cookie or is that did automagically?

  • Cakephp: Correct way to resolve hasMany - hasMany relation

    - by Chris
    I have three models: Company, Car, Passenger Company hasMany Cars Car hasMany Passenger These relations seem to work independetly: Car shows all Passengers and Company shows all Cars. But I cannot resolve the Company - Passenger (Show all Passengers of a Company). My controller for Company: function index(){ //grab all companies and pass it to the view: $companies = $this->Company->find('all'); $this->set('companies', $companies); } This displays all companies with all their respective cars. However the array does not contain an entry for passenger. What do I have to do to completely resovle the Company - Car - Passenger relation?

  • How do I get secure AuthSub session tokens in PHP ?

    - by robertdd
    I am using the Google/YouTube APIs to develop web application which needs access to a users YouTube account. Normal unsecure requests work fine and I can upgrade one time tokens to session tokens without any hassle. The problem comes when I try and upgrade a secure token to a session token, I get: ERROR - Token upgrade for CIzF3546351vmq_P____834654G failed : Token upgrade failed. Reason: Invalid AuthSub header. Error 401 i use this: function updateAuthSubToken($singleUseToken) { try { $client = new Zend_Gdata_HttpClient(); $client->setAuthSubPrivateKeyFile('/home/www/key.pem', null, true); $sessionToken = Zend_Gdata_AuthSub::AuthSubRevokeToken($sessionToken, $client); $client->setAuthSubToken($sessionToken); } catch (Zend_Gdata_App_Exception $e) { print 'ERROR - Token upgrade for ' . $singleUseToken .

    Hi guys, I am here as a developer of a website. My website got different modules among which one function is to process credit card. In order to process credit card I need to implement SSL layer and process the pages. For rest of modules the SSL is optional. Now my points are: 1.) Is the location of file for http and https same? 2.) Can the session of http and https be shared? this is required as i need user login information and cart item information.

  • Problem with Marshalling char* in c#

    - by chrmue
    I have a problem calling this function from a c++ DLL in c# INT32 WINAPI PM_COM_GetText(INT32 TextId, char* pBuf, INT32 BufSize); It writes a Text in a buffer for a given text id. I try to call it with the following c# code, but I constantly get an access violation and don't undrestand why: public string GetText(Int32 TextId) { Int32 BufSize = 256; StringBuilder Str = new StringBuilder(BufSize); PM_COM_GetText(TextId, Str, BufSize); return Str.ToString(); } [DllImport("ComDll.dll", CharSet = CharSet.Ansi)] private static extern Int32 PM_COM_GetText(Int32 TextId, StringBuilder Str, Int32 BufSize); I don't see what's wrong, it looks to me like many other code snippets I found in the web. Any ideas? Thanks in advance!

  • Probability distribution for sms answer delays

    - by Thomas Ahle
    I'm writing an app using sms as communication. I have chosen to subscribe to an sms-gateway, which provides me with an API for doing so. The API has functions for sending as well as pulling new messages. It does however not have any kind of push functionality. In order to do my queries most efficient, I'm seeking data on how long time people wait before they answer a text message - as a probability function. Extra info: The application is interactive (as can be), so I suppose the times will be pretty similar to real life human-human communication. I don't believe differences in personal style will play a big impact on the right times and frequencies to query, so average data should be fine.

  • Why ruby object has two to_s and inspect methods that do the same thing? Or, so it seems.

    - by prosseek
    The p calls inspect, and puts/print calls to_s for representing its object. If I run class Graph def initialize @nodeArray = Array.new @wireArray = Array.new end def to_s # called with print / puts "Graph : #{@nodeArray.size}" end def inspect # called with p "G" end end if __FILE__ == $0 gr = Graph.new p gr print gr puts gr end I get G Graph : 0Graph : 0 Then, why does ruby has two functions do the same thing? What makes the difference between to_s and inspect? And what's the difference between puts/print/p? If I comment out the to_s or inspect function, I get as follows. #<Graph:0x100124b88>#<Graph:0x100124b88>

  • Getting a char array from a vector<int>?

    - by Legend
    I am trying to pass a value from C++ to TCL. As I cannot pass pointers without the use of some complicated modules, I was thinking of converting a vector to a char array and then passing this as a null terminated string (which is relatively easy). I have a vector as follows: 12, 32, 42, 84 which I want to convert into something like: "12 32 42 48" The approach I am thinking of is to use an iterator to iterate through the vector and then convert each integer into its string representation and then add it into a char array (which is dynamically created initially by passing the size of the vector). Is this the right way or is there a function that already does this?

  • bash bcmath functions

    - by Gordon
    I have two functions for GNU bc in a Bash script. BC_CEIL="define ceil(x) { if (x>0) { if (x%1>0) return x+(1-(x%1)) else return x } else return -1*floor(-1*x) }\n" BC_FLOOR="define floor(x) { if (x>0) return x-(x%1) else return -1*ceil(-1*x) }\n" echo -e "scale=2"$BC_CEIL$BC_FLOOR"ceil(2.5)" | bc Both functions work fine in interactive bc. bc does not seem to allow multiple functions on one line separated by ; though, so I have to echo -n | bc with newlines at the end of each function. The above output is 2.5, not the expected 3.0 that I get if I type it into bc -i myself. It seems that bash calls bc for each line of echo output, rather than echo'ing it all to a single instance. Is there any workaround for this?

  • How to cancel drop event in YUI drag & drop utility?

    - by gk
    We are using drag & drop utility between one source and multiple targets. We have a restriction that one of the target can only have one child element while the other ones can have multiple items. I have tried subscribing dragDropEvent of the proxy item and returning false in case the destination target has multiple child elements, with out much luck. var m = new YAHOO.example.DDList("dli" + j, 'documentSelection'); m.subscribe('dragDropEvent', function(e){ if (e.info == 'ulMasterDocument' && $('#ulMasterDocument').children().length > 1){ e.event.canceBubble = true; return false; } return true; }); Is this code correct? Or do i need to subscribe some other event? Thanks

  • remove json attribute where attribute is a variable

    - by pedalpete
    I have a news feed where items in the feed are created from JSON returned from a server. When the user takes an action on an item, I want to remove it from the object via javascript. The feed looks like this: {"newsFeed":[{"feedId":"1", "title":"item1 title", "desc":"description of the item"}, {"feedId":"2", "title":"item2 title", "desc":"description of the item"}]} I'm trying to remove a JSON attribute or entry where the feedId is passed in via a variable using jQuery. I'm not sure exactly where I'm going wrong here, but when I alert the feed before and after the removal of the object, I'm getting the same response: function removeFromFeed(feedId){ var newsFeed=jQuery('div#newsFeed').data('newsFeed'); alert(newsFeed.toSource()); delete newsFeed.feedId[feedId] jQuery('div#newsFeed').data('newsFeed',newsFeed); alert(newsFeed.toSource()); }

  • How to create Server-side Progress indicator in Javascript

    - by Eli
    Hey Guys, I want to create a section in my site, where a user has a few simple update buttons. Each of these update buttons will be going to the server, and will do a long crunching behind the scene. While the server crunches data, I want the user to have a some kind of progress indicator, like progress bar or textual percentage. I'm using jQuery as my javascript library, and CodeIgniter (PHP) as the server-side framework, if it's important... What I was thinking about is using PHP's flush() function to report progress status to jQuery, but I'm not sure that jQuery's ajax functions are reading the output before it's complete... So any advice/explanation would be useful and helpful! Thanks :)

  • navigateToUrl AS3 is not opening a web browser

    - by Ronnie
    I have a textField on my stage named 'adBuy', which when clicked I want to open up my browser with the defined in URL request. However when I click on the 'adBuy' textField on my SWF it opens Coda, the piece of software I'm using to write this small piece of code? I am puzzled. Here is my code: adBuy.defaultTextFormat = adFormat; adBuy.textColor = 0xFF65CB; adBuy.x = 640; adBuy.y = 455; adBuy.text = "Buy Now"; parent.addChild(adBuy); adBuy.addEventListener(MouseEvent.CLICK, buyAdvert); var request:URLRequest = new URLRequest("http://www.google.co.uk"); function buyAdvert(event:MouseEvent):void { navigateToURL(request, "_blank"); trace("link clicked"); } Is there an error in my code, or is this a common problem for which there is an answer?

  • Compiling OpenSSL for boost asio for Microsoft Visual Studio 2010

    - by user560106
    I compiled boost with bjam, and then I compiled OpenSSL. Both of them work separately. I set up the links in Visual Studio 10 to point to my OpenSSL library directory. But when I attempt to compile example boost ssl asio programs I get 44 unresolved external linker errors like this one: 1testing.obj : error LNK2019: unresolved external symbol _SSLv23_server_method referenced in function "public: void __thiscall boost::asio::ssl::detail::openssl_context_service::create(struct ssl_ctx_st * &,enum boost::asio::ssl::context_base::method)" (?create@openssl_context_service@detail@ssl@asio@boost@@QAEXAAPAUssl_ctx_st@@W4method@context_base@345@@Z) Can you please give me step-by-step instructions on properly linking OpenSSL to boost? Thank you so much

  • Direct2D window black when not in focus

    - by Saul Rennison
    Hi all, I have a Direct2D window which paints fine when in focus; however, when focus moves to another window (same application or another), the entire window goes black. I pinned the issue down to the use of ID2D1HwndRenderTarget::Clear. This function is vital to my application as without it, painting becomes rather... weird. Is there a way an un-focused Direct2D window can paint as normal (note: WM_PAINT is being called as usual, as is Clear, BeginPaint, etc. all without error) Thanks in advance.

  • Xpath and parameters

    - by Daniel
    I am relatively new to XSL and I think this is a basic question. So I better get my apologies in early! Basically, I would like to use a value-of function. This will be in a template and I would like to pass part of the xpath as a parameter. <xsl:variable name="TEST_VAR">"h:elementA/elementB"</xsl:variable> ... and then use the variable (or passed in param) as all (or part) of the xpath: <xsl:element name="transformedElement"><xsl:value-of select=$TEST_VAR/></xsl:element> I would really like to have the xpath to be a mixture of string literals and the vlue of TEST_VAR. Thanks in advance

  • No Binary File Generation

    I've just bought a new laptop for me on the travel, then on my free time, I've started to test MinGW on it by trying to compile my own OS that is written in C++, then I've created all the files needed and the kernel.cpp: extern "C" void _main(struct multiboot_data* mbd, unsigned int magic); void _main( struct multiboot_data* mbd, unsigned int magic ) { char * boot_loader_name =(char*) ((long*)mbd)[16]; /* Print a letter to screen to see everything is working: */ unsigned char *videoram = (unsigned char *) 0xb8000; videoram[0] = 65; /* character 'A' */ videoram[1] = 0x07; /* forground, background color. */ } And tried to compile it with g++ G: g++ -o C:\kernel.o -c kernel.cpp -Wall -Wextra -Werror -nostdlib -nostartfiles -nodefaultlibs kernel.cpp: In function `void _main(multiboot_data*, unsigned int)': kernel.cpp:8: warning: unused variable 'boot_loader_name' kernel.cpp: At global scope: kernel.cpp:4: warning: unused parameter 'magic' G: But it don't create any binary file at C:/, what can I do?

  • How fast can you make linear search?

    - by Mark Probst
    I'm looking to optimize this linear search: static int linear (const int *arr, int n, int key) { int i = 0; while (i < n) { if (arr [i] >= key) break; ++i; } return i; } The array is sorted and the function is supposed to return the index of the first element that is greater or equal to the key. They array is not large (below 200 elements) and will be prepared once for a large number of searches. Array elements after the n-th can if necessary be initialized to something appropriate, if that speeds up the search. No, binary search is not allowed, only linear search.

  • How to use custom drawing in QGraphicsViews in PyQt?

    - by DSblizzard
    I need to view QGraphicsScene in 2 QGraphicsViews with condition that they have different scale factors for items in scene. Closest function which I found is drawItems(), but as far I can understand, it must be called manually. How to repaint views automatically? I have these two code fragments in program: class TGraphicsView(QGraphicsView): def __init__(self, parent = None): print("__init__") QGraphicsView.__init__(self, parent) def drawItems(self, Painter, ItemCount, Items, StyleOptions): print("drawItems") Brush = QBrush(Qt.red, Qt.SolidPattern) Painter.setBrush(Brush) Painter.drawEllipse(0, 0, 100, 100) ... Mw.gvNavigation = TGraphicsView(Mw) # Mw - main window Mw.gvNavigation.setGeometry(0, 0, Size1, Size1) Mw.gvNavigation.setScene(Mw.Scene) Mw.gvNavigation.setSceneRect(0, 0, Size2, Size2) Mw.gvNavigation.show() _init_ works, Mw.gvNavigation is displayed and there are Mw.Scene items in it, but drawItems() isn't called.
