  • Is there a good tutorial for figuring out what a website is doing so your program can do the same th

    - by brian d foy
    Is there a good guide or tutorial for people who need to programmatically interact with dynamic websites? There's been a rash of Perl questions about that lately, and I haven't found a good resource to point people toward. I'm asking not because I need one but because I don't want to waste my time writing it if it already exists. Although I'm most interested in Perl, the extra tools and techniques are mostly the same. Typically, I see see these problems in people's questions: Handling, setting, and saving cookies Finding and interacting with forms Handling JavaScript inside your user-agent especially things like onLoad, onSumbit, and Ajax Using HTTP sniffer tools Using Web developer plugins in interactive browsers Interacting with DOM, screen scraping, etc. If there's no good tutorial, I'll add it to my list of things to do (unless someone else wants to do it :). Along the way, if you don't have a suggestion for an existing tutorial, please suggest the things that you think should be in a new one, including links, your favorite tools, and your own user-agent development experiences. I don't care about the particular language you use.

    I enabled HTTPS on the Apache server (2.2.15) Windows 7 Enterprise by uncommenting: Include /private/etc/apache2/extra/httpd-ssl.conf in C:\Program Files (x86)\Apache Software Foundation\Apache2.2\conf\httpd.conf and modifying C:\Program Files (x86)\Apache Software Foundation\Apache2.2\conf\httpd-ssl.conf to include: DocumentRoot "C:/Program Files (x86)/Apache Software Foundation/Apache2.2/htdocs" ServerName myserver.com:443 ServerAdmin [email protected] ...

  • How to embed multiple jQuery line of code in custom HtmlHelpers ASP.NET MVC

    - by embarus
    I 've tried to create my own HTML Helper which work fine for my need but I can't embed many lines of jQuery code in my extension HtmlHelpers class. I've tried @ literal for jQuery code I doesn't work or I need to escape every line of code that I thing I not good for multiple line of code. I don't know if there is another way to achieve this problem like << Therefore, I need to include jQuery plugin file and put implement script after HTML tag. I find it would be convenience if I could put every in HTML helper and put a single line of code in aspx page for example <%= Html.ParentChildSelectList(string parentName, string childName, IEnumerable parentViewData, IEnumerable childViewData, int parentSize, in childSize) % The following code is the way that I used now. the .aspx page Category model.CategoryID)% , new { size = 10 })% model.SubcategoryID,"subcategory") % model.SubcategoryID)% , new { size = 10 })% <script type="text/javascript"> jQuery.sarapadchang.parentChildSelectList( { parentId : "CategoryID" , childId : "SubcategoryID", actionName : "GetSubcategoryList", controllerName : "Json" } ); </script> I put in head tag to include ParentChildSelectList.js the following code for ParentChildSelectList.js (function($) { $.sarapadchang = { parentChildSelectList: function(options) { // $("#CategoryID option").click(function() $("#" + options.parentId).find("option").click(function() { $("#" + options.childId).empty(); //clear data $("#" + options.childId).append('<option>loading...</option>'); $.post("/" + options.controllerName + "/" + options.actionName + "/" + $(this).attr('value'), "", function(data) { var html = ""; $.each(data, function(index, entry) { html += '<option value="' + entry['Value'] + '">' + entry['Text'] + '</option>'; } ); $("#" + options.childId).empty() $("#" + options.childId).append(html); }, "json"); //end getJson }); })(jQuery); To illustrate you, I've attached simple solution, please follow this link. http://www.thaileaguefc.net/ParentChildSelectList.rar Please accept my apologies if my English is difficult to understand.

  • Why is the Clojure Hello World program so slow compared to Java and Python?

    - by viksit
    Hi all, I'm reading "Programming Clojure" and I was comparing some languages I use for some simple code. I noticed that the clojure implementations were the slowest in each case. For instance, Python - hello.py def hello_world(name): print "Hello, %s" % name hello_world("world") and result, $ time python hello.py Hello, world real 0m0.027s user 0m0.013s sys 0m0.014s Java - hello.java import java.io.*; public class hello { public static void hello_world(String name) { System.out.println("Hello, " + name); } public static void main(String[] args) { hello_world("world"); } } and result, $ time java hello Hello, world real 0m0.324s user 0m0.296s sys 0m0.065s and finally, Clojure - hellofun.clj (defn hello-world [username] (println (format "Hello, %s" username))) (hello-world "world") and results, $ time clj hellofun.clj Hello, world real 0m1.418s user 0m1.649s sys 0m0.154s Thats a whole, garangutan 1.4 seconds! Does anyone have pointers on what the cause of this could be? Is Clojure really that slow, or are there JVM tricks et al that need to be used in order to speed up execution? More importantly - isn't this huge difference in performance going to be an issue at some point? (I mean, lets say I was using Clojure for a production system - the gain I get in using lisp seems completely offset by the performance issues I can see here). The machine used here is a 2007 Macbook Pro running Snow Leopard, a 2.16Ghz Intel C2D and 2G DDR2 SDRAM. BTW, the clj script I'm using is from here and looks like, #!/bin/bash JAVA=/System/Library/Frameworks/JavaVM.framework/Versions/1.6/Home/bin/java CLJ_DIR=/opt/jars CLOJURE=$CLJ_DIR/clojure.jar CONTRIB=$CLJ_DIR/clojure-contrib.jar JLINE=$CLJ_DIR/jline-0.9.94.jar CP=$PWD:$CLOJURE:$JLINE:$CONTRIB # Add extra jars as specified by `.clojure` file if [ -f .clojure ] then CP=$CP:`cat .clojure` fi if [ -z "$1" ]; then $JAVA -server -cp $CP \ jline.ConsoleRunner clojure.lang.Repl else scriptname=$1 $JAVA -server -cp $CP clojure.main $scriptname -- $* fi

    I'm trying to run sample Perl script on Windows 7 and I configured IIS 7 to allow ActivePerl to run but I'm getting this error: HTTP Error 502.2 - Bad Gateway The specified CGI application misbehaved by not returning a complete set of HTTP headers. The headers it did return are "Hello World. ".

  • May I open my own device driver twice simultanoiusly from a user program under Linux?

    - by Viktor Gyuris
    Somewhere I read that opening the same file twice has an undefined semantics and should be avoided. In my situation I would like to open my own device multiple times associating multiple file descriptors to it. The file operations of my device are all safe. Is there some part of Linux between the sys call open() and the point it calls the registered file operation .open() that is unsafe?

  • Is there any way to use getaddrinfo() and freeaddrinfo() and still be the program compatible with le

    - by Sam C.
    Hi, in the Winsock2 library getaddrinfo() and freeaddrinfo() was only added in Windows XP and on. I know how to replace them in legacy systems, but a conditional use depending on the Windows version won't help. The application won't start in 9x with a message saying that it was linked to a missing export in WS2_32.dll. I'm using MinGW to compile and link the code and would like to keep using it. Maybe writing those functions by myself? Thank you very much for everything.

  • How to check with program in other programming-language (C,C++, etc) whether JAVA is installed and w

    - by Andreas Hornig
    Hi, I would like to know whether or not JAVA is installed and where (path). Perhaps it sounds strange, but my aim is to let BOINC (coded in C++) check the JAVA installation and then start my JAVA app. But therefore I need to know if BOINC can start JAVA natively, or if I have to also send the JRE and then start my app with this not installed JRE. So is there a way to check the installation first? thank you in advance! Andreas

  • Why does my ActivePerl program report 'Sorry. Ran out of threads'?

    - by Zaid
    Tom Christiansen's example code (à la perlthrtut) is a recursive, threaded implementation of finding and printing all prime numbers between 3 and 1000. Below is a mildly adapted version of the script #!/usr/bin/perl # adapted from prime-pthread, courtesy of Tom Christiansen use strict; use warnings; use threads; use Thread::Queue; sub check_prime { my ($upstream,$cur_prime) = @_; my $child; my $downstream = Thread::Queue->new; while (my $num = $upstream->dequeue) { next unless ($num % $cur_prime); if ($child) { $downstream->enqueue($num); } else { $child = threads->create(\&check_prime, $downstream, $num); if ($child) { print "This is thread ",$child->tid,". Found prime: $num\n"; } else { warn "Sorry. Ran out of threads.\n"; last; } } } if ($child) { $downstream->enqueue(undef); $child->join; } } my $stream = Thread::Queue->new(3..shift,undef); check_prime($stream,2); When run on my machine (under ActiveState & Win32), the code was capable of spawning only 118 threads (last prime number found: 653) before terminating with a 'Sorry. Ran out of threads' warning. In trying to figure out why I was limited to the number of threads I could create, I replaced the use threads; line with use threads (stack_size => 1);. The resultant code happily dealt with churning out 2000+ threads. Can anyone explain this behavior?

  • Best way to hide a window from the Alt-Tab program switcher?

    - by chaiguy1337
    I've been a .NET developer for several years now and this is still one of those things I don't know how to do properly. It's easy to hide a window from the taskbar via a property in both Windows Forms and WPF, but as far as I can tell, this doesn't guarantee (or necessarily even affect) it being hidden from the Alt-Tab dialog. I've seen invisible windows show up in Alt-Tab, and I'm just wondering what is the best way to guarantee a window will never appear (visible or not) in the Alt-Tab dialog. Update: Please see my posted solution below. I'm not allowed to mark my own answers as the solution, but so far it's the only one that works. Update 2: There's now a proper solution by Franci Penov that looks pretty good, but haven't tried it out myself. Involves some Win32, but avoids the lame creation of off-screen windows.

  • How do I program an AVR Raven with Linux or a Mac?

    - by Andrew McGregor
    This tutorial for programming these starts with programming the Ravens and Jackdaw with a Windows box. Can I do those initial steps with avrdude on a Linux or OS X machine instead? If so, how? Is there any risk of bricking the hardware if I just try? I have a USB JTAG ICE MKii clone, which is supposed to work for this. I'm totally new to AVR, but very experienced with C/C++ programming on Linux or OS X, up to and including kernel programming... so any hint at all would be appreciated, I can read man pages, but only if I know what I'm looking for.

  • For how long can a file be locked in windows after program is closed?

    - by Skadlig
    In a couple of scripts that I use I have problem that is intermittent. Sometimes the script fails when trying to delete a file. According to the error log due to the file being accessed by an other process. I'm guessing that windows not had time to release the file after the previous operation performed on the file ended. What amount of time would be a good guesstimate after which windows should have had time to release the file again?

  • How to add my program to the OS X system menu bar?

    - by Joe
    I have created a volume controller for iTunes but I would like this app to place an icon on the OS X system menu bar and have my slider controller drop down. I created this because I have to switch to iTunes to change the volume of the music because I am using the digital-out audio and the keyboard keys do not work in digital-out mode. Any guidance would be greatly appreciated.

  • How can I make my Perl Jabber bot an event-driven program?

    - by TheGNUGuy
    I'm trying to make a Jabber bot and I am having trouble keeping it running while waiting for messages. How do I get my script to continuously run? I have tried calling a subroutine that has a while loop that I, in theory, have set up to check for any messages and react accordingly but my script isn't behaving that way. Here is my source: http://pastebin.com/03Habbvh # set jabber bot callbacks $jabberBot-SetMessageCallBacks(chat=\&chat); $jabberBot-SetPresenceCallBacks(available=\&welcome,unavailable=\&killBot); $jabberBot-SetCallBacks(receive=\&prnt,iq=\&gotIQ); $jabberBot-PresenceSend(type="available"); $jabberBot-Process(1); sub welcome { print "Welcome!\n"; $jabberBot-MessageSend(to=$jbrBoss-GetJID(),subject="",body="Hello There!",type="chat",priority=10); &keepItGoing; } sub prnt { print $_[1]."\n"; } #$jabberBot-MessageSend(to=$jbrBoss-GetJID(),subject="",body="Hello There!
