  • Is there a function that can read a php function post-parsing?

    - by Rob
    I've got a php file echoing hashes from a MySQL database. This is necessary for a remote program I'm using, but at the same time I need my other php script opening and checking it for specified strings POST parsing. If it checks for the string pre-parsing, it'll just get the MySQL query rather than the strings to look for. I'm not sure if any functions do this. Does fopen() read the file prior to parsing? or file_get_contents()? If so, is there a function that'll read the file after the php and mysql code runs? The file with the hashes query and echo is in the same directory as the php file reading it, if that makes a difference. Perhaps fopen reads it post-parse, and I've done something wrong, but at first I was storing the hashes directly in the file, and it was working fine. After I changed it to echo the contents of the MySQL table, it bugged out.

  • In Python, how to use a C++ function which returns an allocated array of structs via a ** parameter?

    - by Jon-Eric
    I'd like to use some existing C++ code, NvTriStrip, in a Python tool. SWIG easily handles the functions with simple parameters, but the main function, GenerateStrips, is much more complicated. What do I need to put in the SWIG interface file to indicate that primGroups is really an output parameter and that it must be cleaned up with delete[]? /////////////////////////////////////////////////////////////////////////// // GenerateStrips() // // in_indices: input index list, the indices you would use to render // in_numIndices: number of entries in in_indices // primGroups: array of optimized/stripified PrimitiveGroups // numGroups: number of groups returned // // Be sure to call delete[] on the returned primGroups to avoid leaking mem // bool GenerateStrips( const unsigned short* in_indices, const unsigned int in_numIndices, PrimitiveGroup** primGroups, unsigned short* numGroups, bool validateEnabled = false ); FYI, here is the PrimitiveGroup declaration: enum PrimType { PT_LIST, PT_STRIP, PT_FAN }; struct PrimitiveGroup { PrimType type; unsigned int numIndices; unsigned short* indices; PrimitiveGroup() : type(PT_STRIP), numIndices(0), indices(NULL) {} ~PrimitiveGroup() { if(indices) delete[] indices; indices = NULL; } };

  • How to declare a function that accepts a lambda?

    - by Andreas Bonini
    I read on the internet many tutorials that explained how to use lambdas with the standard library (such as std::find), and they all were very interesting, but I couldn't find any that explained how I can use a lambda for my own functions. For example: int main() { int test = 5; LambdaTest([&](int a) { test += a; }); return EXIT_SUCCESS; } How should I declare LambdaTest? What's the type of its first argument? And then, how can I call the anonymous function passing to it - for example - "10" as its argument?

  • Checking if parsed date is within a date range

    - by Brett Powell
    So I am using a scripting language with c++-like syntax, and I am trying to think of the best way to check if a date is within range. The problem I am running into is that if the current day is in a new month, the check is failing. Here is what my code looks like: if(iMonth >= iStartMonth && iMonth <= iEndMonth) { if(iDay >= iStartDay && iDay <= iEndDay) { if(iYear >= iStartYear && iYear <= iEndYear) { bEnabled = true; return; When I have something like this: Start date: 3 27 2010 End Date: 4 15 2010 Current Date: 3 31 2010 The day check fails because if (iDay <= iEndDay) does not pass. The scripting language doesn't have a lot of time related functions, and I can't compare timestamps because I'm allowing users to put like "03:27:2010" and "04:15:2010" as start/end dates in a config file. I'm assuming I am just not thinking straight and missing an easy fix.

  • Finding many local max in an image (using MatLab)

    - by wenh42
    How do you go about figuring our multiple max in a 2D image where the max aren't necessarily all the same height? I have found that the imregionalmax(), imextendedmax(), and findpeaks() functions aren't necessarily that helpful because they give many local max that are really just maxes within the background noise. I tried bw=arrayimdilate(array,[1 1 1; 1 0 1; 1 1 1]) but that also is kind of limited for the same reasons (same thing with expanding the matrix that it uses). I'd definitely appreciate some help..

  • How to have favicon / icon set when bookmarklet dragged to toolbar?

    - by Pistos
    I've made myself a bookmarklet, and it functions just fine, but when added to a toolbar in Opera or Firefox, it just takes on the default bookmark icon for the browser (a globe and a star, respectively). My site has a favicon, and the window, tab and even [site] bookmark uses the favicon I've specified. Just not my bookmarklet. How can I code my site or bookmarklet so that the bookmarklet gets the favicon, too? I'm aware of various manual hackery techniques users can use to set the favicon after the fact, but those are undesirable solutions.

  • PHP: $_POST array to XML file and display results.

    - by user633264
    I'm creating a "Madlibs" page where visitors can create funny story things online. The original files are in XML format with the blanks enclosed in XML tags (Such as blablabla <PluralNoun></PluralNoun> blablabla <Verb></Verb> ). The form data is created using XSL and the results are saved using a $_POST array. How do I post the $_POST array between the matching XML tags and then display the result to the page? I'm sure it uses a "foreach" statement, but I'm just not familiar enough with PHP to figure out what functions to use. Any help would be great. Thanks, E

  • How to modify the HTML and BODY tags in an ASP.NET page without adding runat=server to the elements?

    - by jon333
    In an ASP.NET web forms project that is not quite ready to be upgraded from 2.0 to 4.0 , there is a change that needs to be made to allow modifications to the HTML and BODY tags on the pages without adding runat=server to the tags which results in the 2.0 styled "ugly ids" like "ctrl_100..." For example, how could we change these using JavaScript, a Response Filter (the regex to find these specific tags would really help on this one), or something else...from: <html xmlns="//www.w3.org/1999/xhtml"> <body> To: <html lang="jp=JP" xmlns="//www.w3.org/1999/xhtml" dir="rtl"> <body dir="rtl"> JavaScript seems like a possibility, but functions from the server-side could would determine the language and direction the page should have.

  • Read Text From Windows Form

    - by omghai2u
    I would like, if for no other reason that an academic exercise, to be able to read text written to a form on a Windows Application. The program appears to be written in non-.NET, but in .NET terms, I think you would describe the program as having a Form with a Label and I would like to read the text from that label. I believe I can see that text being written to the screen with the User32!TextOut (and in other areas User32!DrawString) function. However, it would be nice if I didn't have to hook that function to get the information I'm looking for, but instead if I could just read it from the form directly. So, given a handle to a Window, is it possible to read the text that has been written to that window with functions like TextOut and DrawString using some similar API or other clever means? Or am I going about this the wrong way? Should I just hook the function and look for the text in every call and pray? Thanks!

  • C++ Thread Safe Integer

    - by Paul Ridgway
    Hello everyone, I have currently created a C++ class for a thread safe integer which simply stores an integer privately and has public get a set functions which use a boost::mutex to ensure that only one change at a time can be applied to the integer. Is this the most efficient way to do it, I have been informed that mutexes are quite resource intensive? The class is used a lot, very rapidly so it could well be a bottleneck... Googleing C++ Thread Safe Integer returns unclear views and oppinions on the thread safety of integer operations on different architectures. Some say that a 32bit int on a 32bit arch is safe, but 64 on 32 isn't due to 'alignment' Others say it is compiler/OS specific (which I don't doubt). I am using Ubuntu 9.10 on 32 bit machines, some have dual cores and so threads may be executed simultaneously on different cores in some cases and I am using GCC 4.4's g++ compiler. Thanks in advance...

  • PHP APC - Why is loading cached array op codes slow?

    - by Aaron Kreider
    I'm using APC to reduce my loading time for my PHP files. My files load very fast, except for one file where I define more than 100 arrays. This 270 kb file takes 200 ms to load. The rest of the files are full of objects, methods, and functions. I'm wondering: does OP code caching not work as well for arrays? My APC cache should be big enough to handle all of my classes. Currently 40% of my cache is free. My hit rate is 99%. apc.shm_size=32 M apc.max_file_size = 1M apc.shm_segments= 1 APC 3.1.6 I'm using PHP 5.2, Apache 2, and Windows Vista.

  • Is is possible to make a shaped, alpha-blended dialog?

    - by jgaa
    I'm making a non-rectangular dialog, modelled over an image from Photoshop (the image is the background of the dialog, and the user will see trough the transparent part of the image). I'ts like a dashboard-style window for a media-app with a few custom-drawn controls. Most of the background-image is either opaque or 100% transparent - but in between there is a thin area of partially transparent pixels, ment to blend the image smootly into the background. This works great for web-graphics, but I have not found a way to make this work for Windows windows. I'm using the Windows Template Library (WTL), msvc 2008 - and the app must run on Windows XP as well as Vista and Windows 7. Currently, I'm simply using the opaque part of the background-image to create a GDI clipping-region, but this gives pretty rough edges. Does anyone know about any API functions to accomplish this (part of WTL, or reachable from WTL)?

  • External GUI/Helper Library for Visual C++?

    - by Psychic
    I am looking for some kind of library, either open source or bought in, that provides advanced GUI components, helper functions & classes etc. It needs to be something that integrates relatively easily into Visual Studio, and should be based around C++ and Windows. Cross platform isn't needed, and can somtimes make things a little more complex and restricted than single platform, but it is still acceptable. It also needs to be up-to-date and active. There appears to be a number of 'retired' libraries that offer little or no support, so these would not be suitable, as I'm going to need help every now and then! It also needs good documentation. I know about wxWidgets but I'm wondering what other alternatives there are? At first glance, wxWidgets doesn't strike me as what I want/need, especially in the GUI area where the visual components seem striking similar to the stock components. I want more custimization! Is there much out there that meets these requirements?

  • Creating a PHP call home "time bomb" to protect my interests

    - by RC
    Hi everyone, I produced a PHP web app for a client some months back that is hosted on their own server. I have still not been paid for this work, and they are giving me the runaround. It turns out that I still have remote admin access to their server, so I can make code changes. What I was thinking of doing was to move the core kernel off-site onto one of my own servers, and program in some kind of callback or include that gets the kernel (critical functions) from my server. Give it two weeks or so for their backups to catch this change, and then pull the plug and exercise leverage. If I do this, they will pay immediately, because the site is a critical one for a very large and influential client of theirs. What is the most effective and easiest way of doing this? What code do I use? Thanks for any pointers.

  • Perl passing argument into eval

    - by ehretf
    I'm facing an issue using eval function. Indeed I have some function name inside a SQL database, my goal is to execute those functions within perl (after retrieve in SQL). Here is what I'm doing, considering that $RssSource-{$k}{Proceed} contains "&test" as a string retrieved from SQL: my $str2 = "ABCD"; eval "$RssSource->{$k}{Proceed}";warn if $@; sub test { my $arg = shift; print "fct TEST -> ", $row, "\n"; } This is working correctly and display: fct TEST -> However I would like to be able to pass $str2 as an argument to $RssSource-{$k}{Proceed} but I don't know how, every syntax I tried return an error: eval "$RssSource->{$k}{Proceed}$str2" eval "$RssSource->{$k}{Proceed}($str2)" eval "$RssSource->{$k}{Proceed}"$str2 eval "$RssSource->{$k}{Proceed}"($str2) May someone tell me how to properly pass an argument to the evaluated function? Thanks a lot for your help Regards. Florent

  • fHow can I get Opera speed-dial and password management features in other browsers?

    - by Howard Guo
    I heavily rely on Opera's speed dial and password management features. Lack of these two features is really stopping me from switching to another web browser such as Chrome or Firefox. Opera's password management has two unique characteristics which I rely on heavily: It saves passwords on all pages, (apparently) despite the page's meta data asking not to save passwords. It offers keyboard shortcut and button to automatically fill in username/passwords and all other fields in a login form, then automatically submit the form. How can I get those functions in other browsers? Thank you!

  • Recursive compilation using gcc

    - by curiousexplorer
    I am using the gcc compiler. My project source tree looks like somewhat like this test$~: tree . . |-- folder | |-- hello.cpp | `-- hello.h `-- main.cpp 1 directory, 3 files test$~: The file main.cpp contains the main() function and all the functions invoked by main.cpp lie in the directory named folder So far in all my little projects I never had to put some source code under a sub-directory. What I am looking for, in short, is some gcc command for recursive compilation in sub-directories and their subdirectories and so on... This command should be invoked from the home directory of the code project.

  • How to solve this problem with lists?

    - by osabri
    what i don't understand in my task here what kind of list i can use, and if it should have 2 attributes key and value ? or only value? with pointers to another node ofc the task: "design a function which create a list using input from the keyboard _ the prefered solution. Assume that some magic stops the input; so the length of a list is not known in advance.(alternative solution: a function which creates explicitly a fixed list. However, all other function can not assume any knowledge about the length of lists). Necessary utilities( additional functions to be created): a function which deallocates the memory used for lists and a function which prints the content of the list. let the element of lists contain a letter. Design a function which create a copy of such list. can't also understand the list line !!!!!???

  • Capturing stdout within the same process in Python

    - by danben
    I've got a python script that calls a bunch of functions, each of which writes output to stdout. Sometimes when I run it, I'd like to send the output in an e-mail (along with a generated file). I'd like to know how I can capture the output in memory so I can use the email module to build the e-mail. My ideas so far were: use a memory-mapped file (but it seems like I have to reserve space on disk for this, and I don't know how long the output will be) bypass all this and pipe the output to sendmail (but this may be difficult if I also want to attach the file)

  • jQuery Click event on object added with JavaScript not working.

    - by Hultner
    I'm work on a quiz for school but I've bumped into a problem. I got a javascript file for custom radio buttons (CUSTOM FORM ELEMNTS by Ryan Fait if it's helping). The script hides the input buttons and adds custom styled spans instead. Now what I want, when I click one of these JavaScript added spans I want to remove disabled for a button called "Next Question" which when pressed takes you to the next question. The reason for this is that I don't want people to accidently got to the next question without choosing a answer. The problem is when I press the added spans nothing happens but when I press another identical span which I have added in the html it works just as intended. The span got the class radio which is the class I'm looking for in the jQuery. Here's the test page with the error on: http://hultner.se/graphicsquiz/livetest/livetest.php Short: Can't get jQuery .click() functions to work with spans added using JavaScript earlier in the document.

  • Fastest PHP Routine To Match Words

    - by Volomike
    What is the fastest way in PHP to take a keyword list and match it to a search result (like an array of titles) for all words? For instance, if my keyword phrase is "great leather shoes", then the following titles would be a match... Get Some Really Great Leather Shoes Leather Shoes Are Great Great Day! Those Are Some Cool Leather Shoes! Shoes, Made of Leather, Can Be Great ...while these would not be a match: Leather Shoes on Sale Today! You'll Love These Leather Shoes Greatly Great Shoes Don't Come Cheap I imagine there's some trick with array functions or a RegEx (Regular Expression) to achieve this rapidly.

  • Display fraction with numerator/denominator with empty fields for users to enter text

    - by Anil
    Hi all I have a scenario in which I need to design online keyboard with buttons implementing different mathematical functions in ASP.NET. For example 1) A button called "Fraction" Onclicking= should display A numerator and a denominator separated by '-' with empty fields. Just as we write fractions manually. Now when the user clicks on this button the cursor should focus on numerator displaying 'the division line' and then by pressing 'Down' arrow key(on computr keyboard) should focus on denominator allowing users to enter both fields. Keeping it simple the user should be able to toggle between numerator and denominator. Please help me with some sample code. I have got no idea. Thanks in advance

  • Jquery - How to make $.post() use contentType=application/json?

    - by JK.
    I've noticed that when using $.post() in jquery that the default contentType is application/x-www-form-urlencoded - when my asp.net mvc code needs to have contentType=application/json (See this question for why I must use application/json: http://stackoverflow.com/questions/2792603/aspnet-mvc-why-is-modelstate-isvalid-false-the-x-field-is-required-when-that) How can I make $.post() send contentType=application/json? I already have a large number of $.post() functions, so I don't want to change to $.ajax() because it would take too much time If I try $.post(url, data, function(), "json") It still has contentType=application/x-www-form-urlencoded. So what exactly does the "json" param do if it does not change the contenttype to json? If I try $.ajaxSetup({ contentType: "application/json; charset=utf-8" }); That works but affects every single $.get and $.post that I have and causes some to break. So is there some way that I can change the behavior of $.post() to send contentType=application/json?

  • Ways not to write function headers twice?

    - by mee
    Hi, I've got a C/C++ question, can I reuse functions across different object files or projects without writing the function headers twice? (one for defining the function and one for declaring it) I don't know much about C/C++, Delphi and D. I assume that in Delphi or D, you would just write once what arguments a function takes and then you can use the function across diferent projects. And in C you need the function declaration in header files *again??, right?. Is there a good tool that will create header files from C sources? I've got one, but it's not preprocessor-aware and not very strict. And I've had some macro technique that worked rather bad. I'm looking for ways to program in C/C++ like described here http://www.digitalmars.com/d/1.0/pretod.html

  • Efficient implementation of threads in the given scenario

    - by shadeMe
    I've got a winforms application that is set up in the following manner: 2 buttons, a textbox, a collection K, function X and another function, Y. Function X parses a large database and enumerates some of its data in the global collection. Button 1 calls function X. Function Y walks through the above collection and prints out the data in the textbox. Button 2 calls function Y. I'd like to call function X through a worker thread in such a way that: The form remains responsive to user input. This comes intrinsically from the use of a separate thread. There is never more than a single instance of function X running at any point in time. K can be accessed by both functions at all times. What would be the most efficient implementation of the above environment ?
