  • which one consume less resources? opening text file or make an sql query,both a thousand times ?

    - by imin
    hi I've a php website which displays recipes www.trymasak.my, to be exact. The recipes being displayed at the index page is updated about once a day. To get the latest recipes, I just use a mysql query which is something like "select recipe_name, page_views, image from table order by last_updated". So if I got 10000 visitors a day, obviously the query would be made 10000 times a day. A friend told me a better way (in terms of reducing server load) is when I update the recipes, I just put in the latest recipe details (names,images etc) into a text file, and make my page instead of querying a same query for 10,000 times, just get the data from the text file. Is his suggestion really better? If yes, which is the best php command should I use to open, read and close the text file? thanks

  • Is call to function object inlined?

    - by dehmann
    In the following code, Foo::add calls a function via a function object: struct Plus { inline int operator()(int x, int y) const { return x + y; } }; template<class Fct> struct Foo { Fct fct; Foo(Fct f) : fct(f) {} inline int add(int x, int y) { return fct(x,y); // same efficiency adding directly? } }; Is this the same efficiency as calling x+y directly in Foo::add? In other words, does the compiler typically directly replace fct(x,y) with the actual call, inlining the code, when compiling with optimizations enabled?

  • jquery .click function not getting triggered

    - by aakashbhowmick
    I have the following HTML and Javascript code. I am trying to make a search suggestion system. The list-items in the unordered-list 'search_suggest' are retrieved dynamically using ajax as the user types in the input box 'site_search' and inserted. <form name="search_site_form" method="get" action="search.php"> <input id="site_search" name="q" class="search_input input" autocomplete="off" value="Search the site" type="text"/> <ul id="search_suggest"> </ul> <input value=" " type="submit" class="search_submit"/> <script type="text/javascript"> <!-- $("ul#search_suggest>li").click(function(){ alert('123'); }); //--> </script> </form> Clicking on the list items in search_suggest however is not triggering the click function. Any idea why?

  • Notepad++ or other application to replace string with numeric function

    - by user38963
    Hello. I am using Notepad++ and attempting to replace all numeric strings within a specific tag (xxxxof my XML document with a new string which has been modified by a specific variable. Here's an example (please remove the space between < and start): < start501234< /start round(501234 * 0.9) = 451111 < start451111< /start Is there a way to automatically find all numeric values within the start tag and do replace it by that same value multiplied by 0.9? I don't have to use Notepad++ if there's another tool that can do this. Thanks!

  • Function to get a string and return same after processing in C

    - by C0de_Hard
    I am working on a code which requires a function. This function gets a string as input and returns a string. What I have planned so far is to get a str[], remove all $'s and spaces, and store this in another string which is returned later: char *getstring(char str[]) { int i=0; char rtn[255]; while (i<strlen(str)) { if (str[i] != " " || str[i] != "$" ) rtn[i] = str[i]; else rtn[i] = ''; } return str; } I dont feel like this will work. Any ideas?? :-S

  • How to use different providers for Linq to entities?

    - by Anders Svensson
    I'm trying to familiarize myself a bit more with database programming, and I'm looking at different ways of creating a data access layer for applications. I've tried out a few ways but there is such a jungle of different database technologies that I don't know what to learn. For instance I've tried using datasets with tableadapters. Using that I am able to switch data provider rather easily (by programming against the interfaces such as IDbConnection). This is one thing I would want to achieve. But I also know everyone's talking about LINQ, and I'm trying to get to know that a bit better too. So I have tried using Linq to Sql classes as the data access layer as well, but apparently this is not provider independent (works only for SQL Server). So then I read about the Entity Framework (which just as Linq to SQL apparently has gotten its share of bashing already...). It's supposed to be provider independent everybody says, but how? I tried out a tutorial to create an entity data model, but the only providers to choose from were SQL Server/Express. Just for learning purposes, I would like to know how to use the entity framework with MS Access/OleDb. Also, I would appreciate some input on what is the preferred database technology for data access. Is it LINQ still after all the bashing, or should you just use datasets because they are provider independent? Any pointers for what to learn would be great, because it's just too much to learn it all if I'm not going to use it in the end...!

  • How to call C++ function from C?

    - by claws
    I know this. Calling C function from C++: If my application was in C++ and I had to call functions from a library written in C. Then I would have used //main.cpp extern "C" void C_library_function(int x, int y);//prototype C_library_function(2,4);// directly using it. This wouldn't mangle the name C_library_function and linker would find the same name in its input *.lib files and problem is solved. Calling C++ function from C??? But here I'm extending a large application which is written in C and I need to use a library which is written in C++. Name mangling of C++ is causing trouble here. Linker is complaining about the unresolved symbols. Well I cannot use C++ compiler over my C project because thats breaking lot of other stuff. What is the way out? By the way I'm using MSVC

    Hi again :) I think subject tells everything ... I need this method only. No need to waste about 6Mb of included unit if only thing I need is one method from that unit ( Themes ) ... I was thinking of UxTheme unit, but it did not contain proper function. What Windows DLL do I need to import and what API function this method stands for? Thanks. P.S. Question is intended to cover not only this particular method, but others too as I will need to do same in MSXML and MM units ...

  • Javascript click function for multiple Classes

    - by Jason Bassett
    So basically I have this little social networking site which allow comments. I've built a comment section that will slide down once a user clicks "Comment" and it slides down under the users status. My problem is that right now, the JavaScript only works on ONE post ID, and not the rest obviously seeing you can only use an ID once. But of course if I use classes instead, All the comment sections slide down because now they're all the same class. See below for my HTML and JavaScript. So if someone has a better method out there, please help :) $(function () { $(".comment-box").slideUp(); //when "comment" is clicked, slide down the comment box. if ($(".comment-box-btn").click(function () { $(".comment-box").slideDown(); })); //when "cancel" is clicked, slide up the comment box. if ($(".close-comment-box").click(function () { $(".comment-box").slideUp() })); }); And here's the HTML used //anchor for "Comment" <a class="comment-box-btn" href="#"><i class="icon-comment"></i> Comment</a> //comment box <div class="row comment-box" style="display:none;"> <div class="col-md-12"> <form accept-charset="UTF-8" action="" method="post"> <textarea class="form-control animated" cols="180" id="new-comment" name="comment" placeholder="Comment.." rows="1"></textarea> <div class="text-right" style="margin-top:20px;"> <a class="btn btn-default close-comment-box" href="#"> <span class="glyphicon glyphicon-remove"></span> Cancel</a> <button class="btn btn-info" type="submit">Comment</button> </div> </form> </div> </div>

  • Automatic conversion between methods and functions in Scala

    - by fikovnik
    I would like to understand the rules when can Scala automatically convert methods into functions. For example, if I have following two methods: def d1(a: Int, b: Int) {} def r[A, B](delegate: (A, B) ? Unit) {} I can do this: r(d1) But, when overloading r it will no longer work: def r[A, B, C](delegate: (A, B, C) ? Unit) {} r(d1) // no longer compiles and I have to explicitly convert method into partially applied function: r(d1 _) Is there any way to accomplish following with the explicit conversion? def r[A, B](delegate: (A, B) ? Unit) {} def r[A, B, C](delegate: (A, B, C) ? Unit) {} def d1(a: Int, b: Int) {} def d2(a: Int, b: Int, c: Int) {} r(d1) // only compiles with r(d1 _) r(d2) // only compiles with r(d2 _) There is somewhat similar question, but it is not fully explained.

  • PHP: "Footer function"?

    - by Ricket
    I have a project. It has a good number of PHP files. Each of these files includes a standard header. They don't include a standard footer. Now I want to do something just before the end of every page. I can go through each page and add the footer code, but I was wondering if there is an easier way (and I think I've seen something like it before, though I might be mistaken). Is there a way to set a "hook" or "trigger" function that will be executed at the end of a page, from the included header PHP script? I'm thinking of something like set_error_handler but to handle a page close event. Or like C's atexit function.

  • How to determine magnitude of trigonometric function? C++

    - by seaworthy
    > if (((test>=0) && (test<=90)) || ((test>270) && (test<=360))){n_y=1;} > else {n_y=-1;} I need the magnitude of trigonometric function in order to determine the sign of the trigonometric function for an angle falling into a particular quadrant. My plan is to replace the code above with something equivalent. Here is what I want to do in pseudo-code. n_y = cos(test) / (magnitude of cos (test)); This will give me same thing. Abs() only takes integers. Any help is appreciated.

  • calling javascript function inside orkut iframe

    - by tsetsik
    Hi guys, I'm having a web game loaded in orkut application via iframe so there are the orkut iframe and mine iframe inside the xml. Everything is ok, but now I need to have a button for inviting some friends and wall posts from some features. I didn't find a way for including the orkut javascript in the game's code so the first thing that pops into my mind was to call a custom function in the xml by using: window.parent.myFunction(); but it gives me error: permission denied. I've tried some other ways of reaching that function but the error is the same. Does anybody know a way of doing that or this can't be done ?

  • How to create "lock" (stop updating of cells) in Excel?

    - by Oozi
    My question is pretty simple, but one to which I can't really find a solution myself. I use Excel quite frequently, but rarely the fancy stuff. Anyway, to the point: How do I create a dropmenu that will lock certain cells, rows or columns? (by lock I mean unable to change via hand and stops updating itself). Example: A1 = 5 B1 = A1 * 100 Can I "lock" the B1-cell, so that changing A1 will have no effect on B1 (Will remain at value 500)? I would preferably want to be able to "unlock" the cell as well, instead of simply making function into value. Is this possible? Thanks in advance!
