  • jQuery .html() vs .text() produce different result in .hover() function

    - by Paddy
    I have a issue where in I am using the .hover() function. If I use .text() fuction to add the html (anchor tag) which I am dynamically creating, it works fine, both the functions are called as desired. But when I use the .html() function instead then the second fuction of .hover() is never been called. var i = 0; textItems = new Array(); ////I am putting the value into textItems using the jquery ajax call ////and i get its value from a .each() function. //.text() implementation $('#textArea-id').hover( function() { $('#textArea-id').text(textItems[i]); }, function() { //-->mouseout function is called here } ); //.html() implementation $('#textArea-id').hover( function() { $('#textArea-id').html(textItems[i]); }, function() { //-->mouseout function is never been called } );

  • Slide Effect happening too many times

    - by Abs
    Hello all, I call this functions on onmouseover and onmouseout for several divs. //Takes effect on divs with id, 62,63,64,65... function slide_it(id){ $('#options_'+id).slideToggle('slow'); } The problem is that if I move my mouse over and then mouse out, then again, mouse over and then mouse out. If I do this several times, the slide effect happens the same number of times I moved my mouse over and out of the div, as expected. But I can't figure out how I can do this once? I can set a variable, but I have several divs that this function is used by and I can't think of a simple way of doing this rather than storing things into an array, but this is messy! I really appreciate any help on this that is simple to implement! Thanks all for any help

  • Running a piece of code for a certain amount of time in C#?

    - by Hazem
    Hi I am working on a robot that is capable of motion detection using a webcam. I am doing this in C# The robot moves too fast, so I want to turn it on/off at short time intervals in order to reduce its speed. For example, it will start the engine then wait 0.5 second and turn it off, this cycle repeats every 2 seconds. This way, its speed wont be too fast. I would like to include this in a single function called Move() I just don't know how to do this, especially because my motion detection code runs like 20 times a second. Depending on the position of the obstacle, I may need to disable the Move() function and activate other functions that let the robot move into other directions. Any ideas/suggestions on where am I supposed to start? Thanks a lot!

  • login with users, groups and permissions

    - by Dan Bemowski
    OK, I have a set of tables that I want to use for my user logins. I am guessing that I need a separate model for each table in the database. My tables are as follows: Users - user information such as first and last name, groups_id, status, etc... groups - defines the user groups with id, name, description permissions - defines a list of permissions that a group can have permission_assignments - groups_id and permissions_id. many to many relationship table I am not sure how to go about populating an array that would contain the list of permissions that a user would have based on the group they are in after a successful login. Basically, a user belongs to a group, and the group gets assigned permissions. I want to then be able to validate functions/methods based on weather the logged in user has certain permissions. Any help is appreciated

  • jQuery does not execute on dynamically loaded content,, even on a click events.

    - by sxv
    I have two document.ready functions. The first loads content into div#header. The second one performs a hide function and then a toggle function on the newly loaded content. I am not sure if this is a queueing issue or something, but not even the alert() below is executed when I click the loaded content. Thanks. <script type="text/javascript"> $(document).ready(function() { $("#header").load("/documents/collegeradioheader.txt"); }); </script> <script type="text/javascript"> $(document).ready(function() { $(".hideme").hide(); $(".slick-toggle").click(function() { alert('hi'); $(this).parent().next('div').slideToggle('fast'); .siblings('div:visible').slideUp('fast'); }); }); </script>

  • Did anybody use the constream (constrea.h) lib?

    - by user337938
    Two years ago, I used the conio.h (actually conio2.h for Dev-C++) to create a console form interface. Now I want to make the same thing, but C++ std lib does not provide the needed functions and I don't want to use the old C conio lib. I found some websites which highlights the constream lib, but I have no idea to use it on VS! I tried just copying the header file into my project, but VS show several erros. I believe I am doing something wrong. ps: i got this file: ftp://ftp.cs.technion.ac.il/pub/misc/baram/TC31/INCLUDE/CONSTREA.H

  • Manually manipulating ArrayList

    - by jsan
    I have an assignment where I have to create a deque, however I am not allowed to use any built-in classes or interfaces. I am implementing my deque using an array list. My problem is that when I have to, for instance, add to the beginning of the array list (beginning of the queue), i am not allowed to do this: public void addFirst(ArrayList<Integer> array) { array.add(0, int); } Is there a way to do this without using the add() function? Such as manually adding to the front and shifting the rest of the array to the right? Or maybe creating a new array list and copying...I'm not sure. Any help would be great; I have a bunch of functions to write, and getting the first one done will definitely put me in the right direction. Thanks

  • Storing SQL in MySQL: Insert as Text?

    - by Tim F
    Hey all, Working in a team environment, each one of us has put together our own list of SQL statements that we use to help with our day to day job functions. As the case often is, there may be some redundancy with this, and we are often in need of each other's statements. To circumvent this, I'm looking to put together a small app that can be used to store and search for these SQL statements. To begin with, I'm keeping it basic, just storing and searching the statements. This may build out to be the actual execution at some point in the future, but I'm not concerning myself with this at the time. This will be built with PHP and MySQL - Should I store the SQL as text, or is there something that I need to be concerned with?

  • C++ & C#, how to create wrapper dll in C++ for C# to call instance function in C++ dll?

    - by 5YrsLaterDBA
    Received an unmanaged C++ dll with instance functions which need to be called from my C#. need to write a wrapper C++ dll to bridge the C# and original C++ dll as suggested by experts here. it is new to me and want to learn from you. Header file of the original C++ dll likes this: class EXPORT_MACRO NB_DPSM { private: string sFileNameToAnalyze ; public: NB_DPSM(void); ~NB_DPSM(void); void setFileNameToAnalyze(string FileNameToAnalyze) ; int WriteGenbenchData(string& message) ; }; Start from a Class Library project template or CLR Empty Project template? What's the wrapper code should look like? Anywhere has step by step example for this? thanks,

  • Can single-buffer blocking WSASend deliver partial data?

    - by CodeAngry
    I've pretty much always used send() with sockets and now I'm moving onto the WSA functions. With send(), I have a sendall() helper that ensured all data is delivered even if it didn't happen in one try and a partial send occurred on first call. So, instead of learning the hard way or over-complicating code when I don't have to, decided to ask you: Can a blocking WSASend() send partial data or does it send everything before it returns or fails? Or should I check the bytes sent vs. expected to send and keep at it until everything is delivered? ANSWER: Overlapped WSASend() does not send partial data but if it does, it means the connection has terminated. I've never encountered the case yet.

  • How to reference filtered ng-repeat items from a controller in AngularJS

    - by ParkerDigital
    I have some JSON data that is rendered out via the ng-repeat directive, and the results are then filtered via some checkboxes/drop-downs, and some custom filter functions in my controller. I now want to add a function to my controller that is triggered by an 'ng-change' on some of the checkboxes, that can reference the current list of items in my 'ng-repeat'. I realise I can reference these values from a custom filter, for example $scope.filterProvider = function(item), but this function is then called for each and every item in the ng-repeat, which isn't what I want - I want the function to just be called each time a checkbox is checked/unchecked, and I need that function to be able to reference the items in my ng-repeat...does that make sense to anyone?! And if so, does anyone know how I can do that? Thanks :-)

  • Pass, edit and return variable in C

    - by Supertecnoboff
    I am new to C programming and recently I have been playing around with functions in C programming. But I have a simple problem: Basically I want to pass an integer to a function, have the function edit it and then pass back the integer to the main function. I am working on this but it isn't working..... Here is my code: int update_SEG_values(int DIGIT_1, int DIGIT_2) { // How many tens in the "TEMP_COUNT". DIGIT_2 = ((TEMP_COUNT) / 10); // How much is left for us to display. TEMP_COUNT = TEMP_COUNT - ((DIGIT_2) * 10); // How many ones. DIGIT_1 = ((TEMP_COUNT) / 1); return(DIGIT_1, DIGIT_2); } What am I doing wrong here?

  • How to efficiently render different things at different times in a game?

    - by Baqjohanson
    Sorry for the ambiguous title. What I am wondering is what is an efficient way to alternate rendering between lets say a main menu, options menu, and "in the game." The only two ways I've come up with so far are to have 1 render function, with code for each part (menu, ...) and a variable to control what gets drawn, or to have multiple render functions, and use a function pointer to point to the appropriate one, and then just call the function pointer. I always wonder how more professional games do it.

  • including a string as a parameter to a function in a header file? c++

    - by Nara
    hello everyone, total newbie is here :) i have this header file, zeeheader.h, and i wrote some classes in it, i'm having problems giving a string as a parameter to one of the functions: class DeliTest { public: void DeliCheck(Stack*,string); void ComCheck (unsigned,string); bool EofCheck (unsigned,string); }; as i was implementinng it in the cpp file, i added #include to it, it seemed to be working, for example : as i was writing the "data." i got the "length()" appear by the intellisense, so i thought that it was working, but it wasn't. i got errors like: syntax error : identifier 'string' overloaded member function not found in 'DeliTest' this is one of the fucntions in the cpp file: bool DeliTest::EofCheck(unsigned i, string data) { if (i == data.length()-1) return 1; return 0; } am i supposed to be adding something to the header file??

  • DataTable from TextFile?

    - by Craig
    I have taken over an application written by another developer, which reads data from a database, and exports it. The developer used DataTables and DataAdaptors. So, _dataAdapter = new SqlDataAdapter("Select * From C....", myConnection); and then ExtractedData = new DataTable("CreditCards"); _dataAdapter.Fill(ExtractedData); ExtractedData is then passed around to do different functions. I have now been told that I need to, in addition to this, get the same format of data from some comma separated text files. The application does the same processing - it's just getting the data from two sources. So, I am wondering if I can get the data read into a DataTable, as above, and then ADD more records from a CSV file. Is this possible?

  • C# Get/Set Syntax Usage

    - by RoR
    These are declarations for a Person class. protected int ID { get; set; } protected string Title { get; set; } protected string Description { get; set; } protected TimeSpan jobLength { get; set; } How do I go about using the get/set? In main, I instantiate a Person Tom = new Person(); How does Tom.set/get?? I am use to doing C++ style where you just write out the int getAge() and void setAge() functions. But in C# there are shortcuts handling get and set?

  • Is it possible to wrap calls to statically linked 3rd party library?

    - by robusta
    Hi, I would like to trace calls to some 3rd party library which are made from another 3rd party library. Example: I want to trace calls to library A. My application statically links library B, which in turn is statically linked to library A. In case of dynamic linking I could write library A2 with wrappers for functions which I want to trace of library A and use LD_PRELOAD=A2.so. Then, my wrappers will be called instead, and I will see the trace. In my case I cannot use dynamic linking. Is it possible to achieve the same using static linking? Thanks, Robusta

  • C++: How to design a utility class?

    - by Martijn Courteaux
    Hi, The title says it all. But I don't know if I should go for static methods, just a header, a class, or something else? What would be best practice? But, I don't want to have an instance of a utility class. I want to add functions like: Uint32 MapRGB (int r, int g, int b); const char* CopyString(const char* char); // etc. You know: utility methods...

  • MySQL pivot tables - covert rows to columns

    - by user2723490
    This is the structure of my table: Then I run a query SELECT `date`,`index_name`,`results` FROM `mst_ind` WHERE `index_name` IN ('MSCI EAFE Mid NR USD', 'Alerian MLP PR USD') AND `time_period`='M1' and get a table like How can I convert "index_name" rows to columns like: date | MSCI EAFE Mid NR USD | Alerian MLP PR USD etc In other words I need each column to represent an index and rows to represent date-result. I understand that MySQL doesn't have pivot table functions. What is the easiest way of doing this? I've tried this code, but it generates an error: SELECT `date`, MAX(IF(index_name = 'Alerian MLP PR USD' AND `time_period`='M1', results, NULL)) AS res1, MAX(IF(index_name = 'MSCI EAFE Mid NR USD' AND `time_period`='M1', results, NULL)) AS res2 FROM `mst_ind` GROUP BY `date I need to make the conversion on the query level - not PHP. Please suggest a nice and elegant solution. Thanks!

  • Implementing an iterator over binary tree using C++ 11

    - by user1459339
    I would like to create an iterator over the binary tree so as to be able to use range-based for loop. I understand I ought to implement the begin() and end() function first. Begin should probably point to the root. According to the specification, however, the end() functions returns "the element following the last valid element". Which element (node) is that? Would it not be illegal to point to some "invalid" place? The other thing is the operator++. What is the best way to return "next" element in tree? I just need some advice to begin with this programming.

  • Can jquery capture the dynamic dom events and perform actions

    - by Zombie15
    I just wanted to know if something like this is possible. Jquery should fire some action on certian custom event. Like Whenever a new row is added to dom dynamically to table then i have certain action like change the background color to example red. That should work across the whole site. Somethings like Event listeners in Doctrine2 or Signals in Django EDIT: Basically i want some thing like where i can create custom event $.AddnewEvent(newRowAdded); Then i can customise that event with my own functions like $.newRowAdded(function(){ blah blah });

  • lua function as argument in C

    - by Nil
    I'm going to pass a function to another function which should operate with the passed function. For example: handler(fun1("foo",2)) handler(fun2(1e-10)) The handler is something like calling the passed function many times. I'm going to bind handler, fun1, fun2 to C-functions. fun1 and fun2 are going to return some user data with a pointer to some cpp-class so that I can further recover which function was it. The problem now is that fun1 and fun2 are going to be called before passed to handler. But I don't need this, what I need is the kind of function and its parameters. However, I should be able to call fun1 and fun2 alone without handler: fun1("bar",3) fun2(1e-5) Is it possible to get the context the function is called from? While typing the question, I realized I could do following handler(fun1, "foo",2); handler(fun2, 1e-10);
