  • scanf("%d", char*) - char-as-int format string?

    - by SF.
    What is the format string modifier for char-as-number? I want to read in a number never exceeding 255 (actually much less) into an unsigned char type variable using sscanf. Using the typical char source[] = "x32"; char separator; unsigned char dest; int len; len = sscanf(source,"%c%d",&separator,&dest); // validate and proceed... I'm getting the expected warning: argument 4 of sscanf is type char*, int* expected. As I understand the specs, there is no modifier for char (like %sd for short, or %lld for 64-bit long) is it dangerous? (will overflow just overflow (roll-over) the variable or will it write outside the allocated space?) is there a prettier way to achieve that than allocating a temporary int variable? ...or would you suggest an entirely different approach altogether?

  • setTimeout(fun) with a single argument

    - by Elazar Leibovich
    The HTML5 specifications states that setTimeout can be run without the additional "timeout" argument which is supposed to say after how many milliseconds will the function "handler" be scheduled. handle = window . setTimeout( handler [, timeout [, arguments ] ] ) Schedules a timeout to run handler after timeout milliseconds. Any arguments are passed straight through to the handler. However, I failed to find anywhere which explains what happens when no "timeout" time period is set. An example usage is, the animation implementation int the Raphael library. animationElements[length] && win.setTimeout(animation);

  • Is there good .sol editor for Flash Player 9 Local Shared Objects? Can we build one?

    - by nerdabilly
    There's plenty of them out there but none of them do what I would like them to do. Most of them crash when opening a file or simply corrupt the data. Many don't run at all. It seems to me that most were written 3-4 years ago for AS2 .sols and no longer work with FP9/AS3 sols. I'd attempt to write my own using AIR but I can't find a new spec of the byte format. There's an explanation of the file format here: http://sourceforge.net/docman/display_doc.php?docid=27026&group_id=131628 and another here: http://sourceforge.net/docman/display_doc.php?docid=27026&group_id=131628 but it looks as though both of these docs are a good 4 years old (pre-FP9) and as I'm not skilled or experienced in file formats, writing a new one, especially without an updated spec, is seeming like less and less of a viable option. Ideally I'd like one that can not only read the .sol, but edit and save new values also. Thanks!

  • javascript callback after loop

    - by RobertPitt
    Hey guys, Iv'e just started a new Wordpress blog and i have started to build the JavaScript base! the issue im having is funnction a fucntion that loops several variables and includes the required JS libraries, what i need to do is execute the callback when the loop is finished! Heres my code! var Utilities = { Log : function(item) { if(console && typeof console.log == 'function') { //Chrome console.log(item); } }, LoadLibraries : function(callback) { $.each(Wordpress.required,function(i,val){ //Load the JS $.getScript(Wordpress.theme_root + '/js/plugins/' + val + '/' + val + '.js',function(){ // %/js/plugins/%/%.js Utilities.Log('library Loaded: ' + val); }); }); callback(); } } And the usage is like so! Utilities.LoadLibraries(function(){ Utilities.Log('All loaded'); }); Above you see the execution of callback() witch is being executed before the files are in the dom! i need this called at the end of every library inclusion!

  • error by creating process

    - by Tyzak
    hello i want to get startet with programming with WIN32, therefore i wrote a programm that creates a process but in the line of code where i create the process the programm gets an error an dosn't work (abend). i don't know if the code in programm 1 is wrong or the code in the second programm that should be created by the first. ( I don't know if the code in the first programm after "createprocess" is right because i didn't get further with debugging, because in this line i get the error.(i tested it without the cout,waitforobject and close handle but i didn't work either )). First Programm: #include <iostream> #include <windows.h> #include <string> using namespace std; void main() { bool ret; bool retwait; STARTUPINFO startupinfo; GetStartupInfo (&startupinfo); PROCESS_INFORMATION pro2info; ret = CreateProcess(NULL, L"D:\\betriebssystemePRA1PRO2.exe", NULL, NULL, false, CREATE_NEW_CONSOLE, NULL, NULL, &startupinfo, &pro2info); cout<<"hProcess: "<<pro2info.hProcess<<endl; cout<<"dwProcessId: "<<pro2info.dwProcessId <<endl; retwait= WaitForSingleObject (pro2info.hProcess, 100); retwait= WaitForSingleObject (pro2info.hProcess, 100); CloseHandle (pro2info.hProcess);//prozesshandle schließen retwait= WaitForSingleObject (pro2info.hProcess, 100); ExitProcess(0); } Seconde Programm: #include <iostream> #include <windows.h> #include <string> using namespace std; void main() { int b; b=GetCurrentProcessId(); cout<<b<<endl; cout<<"Druecken Sie Enter zum Beenden"<<endl; cin.get(); //warten bis Benutzer bestätigt Sleep (700); ExitProcess(0); cout<<"test"; } Thanks in advance

  • Using a helper method in a mailer that is defined in a controller

    - by Horace Loeb
    The helper method current_user is defined and made available as a helper in ApplicationController like this: class ApplicationController < ActionController::Base helper_method :current_user def current_user return @current_user if defined?(@current_user) @current_user = current_user_session && current_user_session.record end end My question is how I can use the current_user helper method in a mailer template (obviously it will always return nil, but I'm trying to render a partial that depends on it). Normally when I want to use helpers in a mailer, I do something like add_template_helper(SongsHelper), but since the helper is defined in a class instead of a module I'm not sure what to do

  • How to test an application for correct encoding (e.g. UTF-8)

    - by Olaf
    Encoding issues are among the one topic that have bitten me most often during development. Every platform insists on its own encoding, most likely some non-UTF-8 defaults are in the game. (I'm usually working on Linux, defaulting to UTF-8, my colleagues mostly work on german Windows, defaulting to ISO-8859-1 or some similar windows codepage) I believe, that UTF-8 is a suitable standard for developing an i18nable application. However, in my experience encoding bugs are usually discovered late (even though I'm located in Germany and we have some special characters that along with ISO-8859-1 provide some detectable differences). I believe that those developers with a completely non-ASCII character set (or those that know a language that uses such a character set) are getting a head start in providing test data. But there must be a way to ease this for the rest of us as well. What [technique|tool|incentive] are people here using? How do you get your co-developers to care for these issues? How do you test for compliance? Are those tests conducted manually or automatically? Adding one possible answer upfront: I've recently discovered fliptitle.com (they are providing an easy way to get weird characters written "u?op ?pisdn" *) and I'm planning on using them to provide easily verifiable UTF-8 character strings (as most of the characters used there are at some weird binary encoding position) but there surely must be more systematic tests, patterns or techniques for ensuring UTF-8 compatibility/usage. Note: Even though there's an accepted answer, I'd like to know of more techniques and patterns if there are some. Please add more answers if you have more ideas. And it has not been easy choosing only one answer for acceptance. I've chosen the regexp answer for the least expected angle to tackle the problem although there would be reasons to choose other answers as well. Too bad only one answer can be accepted. Thank you for your input. *) that's "upside down" written "upside down" for those that cannot see those characters due to font problems

    I recently purchased a Sony Bravia TV that comes with Internet capability built in. It supports a number of internet capable widgets and web video streaming apps for sites like youtube, twitter & various yahoo! offerings. I'd like to hack on the SDK, but the only version I can find is Japanese. Is there an English version of the SDK? Where can I find some tutorials/examples?

  • Conditionals in Antlr String Templates

    - by Pat Long - Munkii Yebee
    We are using Antlr StringTemplates to give control over how a Entity's Name is output. The basic Stringtemplate is $FirstName$ $Initial$ $LastName$, $Suffix$, $Degree$ I want to add some smarts to that template so that the commas are only output when necessary i.e. The first comma is only output when there is a Suffix or Degree and the second commas is only output if there is a suffix. I tried the following template string bit it does not work. I guess I have misunderstood $FirstName$ $Initial$ $LastName$ <if(Suffix|Degree)>,<endif>, $Suffix$ <if(Suffix)>,<endif> $Degree$ If it helps we process the templates using this C# StringTemplate stringtemplate = new Antlr.StringTemplate.StringTemplate(template.Data); foreach (Pair<string, string> pair in dictionary) { if (pair.First != null && pair.Second != null) { stringtemplate.SetAttribute(pair.First, pair.Second); } } return stringtemplate.ToString();

  • where to get a wordpress theme review

    - by Ayrton
    Hi I'm currently developing some Wordpress templates and I wanted to get a review by a (semi)professional. I already know quite a bit about Wordpress,CSS, & JS but I was always a lone wolf without any guidance that's why I was wondering where I could find someone (trustworthy) to do something like this and how much he should charge me. It's pure about the code (the PHP, JS & the CSS) I would like to have a review on about (nothing design related). A link to the Wordpress theme I'm talking about: http://demo.wpmonk.com Yours truthfully

  • Computer Vision application(+web interface) for face detection and recognition from database

    - by Kush
    My project is a computer vision java application which should implement the following : A web interface through which the form entry+images(for example a student data) will be stored into a database(Mysql) & images into directory common to my java application. Then the data & images can be retrieved from my java Gui application and I can perform the following operations of image processing through OpenCV. Actually,I want to run the face detection on images retrieved and discard the false entries(no proper face). Also the application user/admin can search an image based on text search(By Id) or By another reference image using face recognition. I am well familiar with Java but the problem is that I need a guidance on how to organise it in a stepwise manner(links appreciated).OpenCv,Php and mySql are really messy.I know doing the openCV stuff within java is real overhead but i really want to do it.But If there is any suggestion to do it elseway please guide me.So any kind of help is a ray of hope for me. Thanks.

  • jquery checkbox help

    - by sea_1987
    The Problem I am trying to run some ajax on one my pages for my website, basically I have three checkboxes all of which on pageload are unselected, when a checkbox is clicked I need to be able load in via ajax the relevant HTML. This system is currently a PHP script that depending on what the POST is set returns a different view, so I think all I need to is send the POST via AJAX, but I need to do everytime a new checkbox is checked. My HTML looks like this, div class="segment"> <div class="label"> <label>Choose region: </label> </div> <div class="column w190"> <div class="segment"> <div class="input"> <input type="checkbox" checked="checked" class="radio checked" value="Y" name="area[Nationwide]" id="inp_Nationwide"> </div> <div class="label "> <label for="inp_Nationwide">Nationwide</label> </div> <div class="s">&nbsp;</div> </div> </div> <div class="column w190"> <div class="segment"> <div class="input"> <input type="checkbox" checked="checked" class="radio checked" value="Y" name="area[Lancashire]" id="inp_Lancashire"> </div> <div class="label "> <label for="inp_Lancashire">Lancashire</label> </div> <div class="s">&nbsp;</div> </div> </div> <div class="column w190"> <div class="segment"> <div class="input"> <input type="checkbox" checked="checked" class="radio" value="Y" name="area[West_Yorkshire]" id="inp_West_Yorkshire"> </div> <div class="label "> <label for="inp_West_Yorkshire">West Yorkshire</label> </div> <div class="s">&nbsp;</div> </div> <div class="s">&nbsp;</div> </div> </div> My current attempt was to ascertain whether the input has been clicked so I have done this with my javascript, though this is probably wrong, $('input.radio').click(function(){ if($(this).hasClass('clicked')) { $(this).removeClass('clicked'); } else { $(this).addClass('clicked'); } });

  • Visualize the depth buffer

    - by Thanatos
    I'm attempting to visualize the depth buffer for debugging purposes, by drawing it on top of the actual rendering when a key is pressed. It's mostly working, but the resulting image appears to be zoomed in. (It's not just the original image, in an odd grayscale) Why is it not the same size as the color buffer? This is what I'm using the view the depth buffer: void get_gl_size(int &width, int &height) { int iv[4]; glGetIntegerv(GL_VIEWPORT, iv); width = iv[2]; height = iv[3]; } void visualize_depth_buffer() { int width, height; get_gl_size(width, height); float *data = new float[width * height]; glReadPixels(0, 0, width, height, GL_DEPTH_COMPONENT, GL_FLOAT, data); glDrawPixels(width, height, GL_LUMINANCE, GL_FLOAT, data); delete [] data; }

  • conversion of a varchar to a smalldatetime results in an out-of-range value

    - by michael
    The code: strSql = "insert into table2 (transactiondate) values ('" & transactiondate & "')" seems to be giving me the runtime error: The conversion of a varchar data type to a smalldatetime data type resulted in an out-of-range value In the code, strSql is a String object and transactiondate is a Date object. In the SQL database however, transactiondate is a smalldatetime object. I've tried changing the smalldatetime to a datetime (in the database) and I've tried transactiondate.toString() but with no success. How can this be fixed? Note: I know about the dangers of inline SQL. I am looking for a quick fix solution here and not a discussion about SQL injection.

  • Options to develop professionally with Microsoft tools and Technologies without spending a lot?

    - by iama
    I would like to develop applications for the Windows platform & at the very least I need a server based Windows OS (2008), SQL Server, IIS and Visual Studio. Looks like VS2010 professional alone will cost over $1K. Is there a cheaper option to get hold of Microsoft software? I remember long time ago there was an MSDN subscription option which allowed user access to server based OS and other server applications with restrictive licensing that was cost effective. I don't see that option anymore. Moreover, I am not a student & I understand Microsoft provides software at discounted rates for students. Any pointers? Many thanks.

  • Linq to SQL ordered child collection

    - by Matt Connolly
    Is there a way to define a default order column from a child collection? In my case, I have a Form entity that has a collection of FormItem entities called FormItems. FormItem has a property called DisplayOrder (int). I want to make sure that any Form entities I return from a method have that collection properly ordered. Is there a way to do this before returning the result? For example, I tried this but the list is not actually sorted: var form = context.Forms.FirstOrDefault(x => x.IsDeleted == false && x.FormName == formName); if (form != null) { form.FormItems.OrderBy(x => x.DisplayOrder); // I can't even figure out a way to cast this next line so that it will compile // form.FormItems = form.FormItems.OrderBy(x => x.DisplayOrder); } return form; Is there a way to do this without using DataLoadOptions?

  • one page over 9 different urls

    - by Ali Demirtas
    Hi I am using prestashop as the cart for my website. I have a problem; the website used to be in dynamic urls. I enabled friendly url writing. The problem is that one page has more than one url. You can access a same page from the dynamic url and static url. In fact a single page has 9 different urls. This obviously creates problems for seo as search engines penalize my website for this. Here are examples of a page with more than 2 urls (http://www.turkishfootballstore.com/lang-nl/product.php?id_product=515) (http://www.turkishfootballstore.com/fenerbahce/515-fenerbahce-thuisshirt-20092010.html) (http://www.turkishfootballstore.com/lang-nl/fenerbahce/515-fenerbahce-thuisshirt-20092010.html) you can see even the static url's have 2 one with language defined and the other without. out fo the three urls above the correct one is the one at the bottom. What can I do to solve this problem? I have no knowledge of programming. Here is the htaccess for the website. Any sample code or help is really appreciated. There is 550 pages and every page is published in 17 different languages I want to use a 301 auto redirect. What is the simplest way to do it? I have no idea of coding. # URL rewriting module activation RewriteEngine on # URL rewriting rules RewriteRule ^([a-z0-9]+)\-([a-z0-9]+)(\-[_a-zA-Z0-9-]*)/([_a-zA-Z0-9-]*)\.jpg$ /img/p/$1-$2$3.jpg [L,E] RewriteRule ^([0-9]+)\-([0-9]+)/([_a-zA-Z0-9-]*)\.jpg$ /img/p/$1-$2.jpg [L,E] RewriteRule ^([0-9]+)(\-[_a-zA-Z0-9-]*)/([_a-zA-Z0-9-]*)\.jpg$ /img/c/$1$2.jpg [L,E] RewriteRule ^lang-([a-z]{2})/([a-zA-Z0-9-]*)/([0-9]+)\-([a-zA-Z0-9-]*)\.html(.*)$ /product.php?id_product=$3&isolang=$1$5 [L,E] RewriteRule ^lang-([a-z]{2})/([0-9]+)\-([a-zA-Z0-9-]*)\.html(.*)$ /product.php?id_product=$2&isolang=$1$4 [L,E] RewriteRule ^lang-([a-z]{2})/([0-9]+)\-([a-zA-Z0-9-]*)(.*)$ /category.php?id_category=$2&isolang=$1 [QSA,L,E] RewriteRule ^([a-zA-Z0-9-]*)/([0-9]+)\-([a-zA-Z0-9-]*)\.html(.*)$ /product.php?id_product=$2$4 [L,E] RewriteRule ^([0-9]+)\-([a-zA-Z0-9-]*)\.html(.*)$ /product.php?id_product=$1$3 [L,E] RewriteRule ^([0-9]+)\-([a-zA-Z0-9-]*)(.*)$ /category.php?id_category=$1 [QSA,L,E] RewriteRule ^content/([0-9]+)\-([a-zA-Z0-9-]*)(.*)$ /cms.php?id_cms=$1 [QSA,L,E] RewriteRule ^([0-9]+)__([a-zA-Z0-9-]*)(.*)$ /supplier.php?id_supplier=$1$3 [QSA,L,E] RewriteRule ^([0-9]+)_([a-zA-Z0-9-]*)(.*)$ /manufacturer.php?id_manufacturer=$1$3 [QSA,L,E] RewriteRule ^lang-([a-z]{2})/(.*)$ /$2?isolang=$1 [QSA,L,E] # Catch 404 errors ErrorDocument 404 /404.php Options +FollowSymLinks RewriteEngine on RewriteCond %{HTTP_HOST} ^***.com [NC] RewriteRule ^(.*)$ http://www.***.com/$1 [L,R=301] Options +FollowSymLinks RewriteEngine on # index.php to / RewriteCond %{THE_REQUEST} ^[A-Z]{3,9}\ /.*index\.php\ HTTP/ RewriteRule ^(.*)index\.php$ /$1 [R=301,L] Header set Cache-Control: "no-store, no-cache, must-revalidate, pre-check=0, post-check=0, max-age=0"

It looks like they are uploading bootlegged DVDs and pirated software. All of my bandwidth and file space is being eaten up. Could this be a shared permissions issue? Where should I look to further investigate this? My security permissions for the directory that is being hit are as followed: Administrators - ALL GRANTED IIS_WPG - Read & Execute, List Folder Contents, Read Internet Guest - DENY SYSTEM - ALL GRANTED Users - Read & Execute, List Folder Contents, Read My Event Viewer is showing many Logon/Logoff with NO IP?

  • display of umlauts in firefox

    - by Mike D
    I was doing some web searching and found some strange things involving umlauts. For example if you do a google or yahoo search for the word "nther" you are likely to find things like G&#xfc;nther which I take to be Gunther with an umlaut over the u. Now my question is what if anything can I do to cause these characters to be properly displayed by Firefox under windows XP? An amazing thing is that I had to introduce spaces in the G & # etc string otherwise it was properly displayed here as u with umlaut!

  • fastest (low latency) method for Inter Process Communication between Java and C/C++

    - by Bastien
    Hello, I have a Java app, connecting through TCP socket to a "server" developed in C/C++. both app & server are running on the same machine, a Solaris box (but we're considering migrating to Linux eventually). type of data exchanged is simple messages (login, login ACK, then client asks for something, server replies). each message is around 300 bytes long. Currently we're using Sockets, and all is OK, however I'm looking for a faster way to exchange data (lower latency), using IPC methods. I've been researching the net and came up with references to the following technologies: - shared memory - pipes - queues but I couldn't find proper analysis of their respective performances, neither how to implement them in both JAVA and C/C++ (so that they can talk to each other), except maybe pipes that I could imagine how to do. can anyone comment about performances & feasibility of each method in this context ? any pointer / link to useful implementation information ? thanks for your help

  • How to do pointer work with accessor methods in Objective-C

    - by Jasconius
    Basic problem statement: I have a very good reason for doing some pointer fanciness in an app where I need to pass a decimal by reference. So I have a class which stores many a decimal, so let's say is has a property as such: @property (nonatomic) double myDecimalValue; I want to pass it by reference to some other class. [someOtherObject sendMyDecimalByReference:&myDecimalValue]; But, a problem emerges! The way that actually has to be written (because it's a property) is [someOtherObject sendMyDecimalByReference:&decimalOrigin.myDecimalValue]; This fails to compile in objective-c I get around it by writing the following - (double *) myDecimalValueRef; [someOtherObject sendMyDecimalByReference:[decimalOrigin myDecimalValue]]; Except I have dozens of these decimals and I don't want to write that stupid wrapper function for every value. Is there a shorthand way to do this in Objective-C using just the Getter functions? Let's just assume I have a great reason for not using NSNumber. Thanks!

  • Selenium and Firefox 9's "Will you help improve Mozilla Firefox" popup

    - by Rup
    I'm trying to test a Java web app using Selenium 2.16.1. When Selenium opens Firefox, I see a band at the top of the page with message "Will you help improve Mozilla Firefox" For some reason this breaks selenium.click("id=submit"); selenium.waitForPageToLoad("60000"); which is trying to log in - it becomes a no-op, and the test fails because it's then expecting to have logged in. If I break on the click line and clear the 'will you help' band before continuing then the form submit succeeds. Is there a way to suppress this band from appearing? (I expect that would mean setting a property in Firefox's default profile - where do I find that?) Or is there a way to get Selenium to spot and dismiss this first? Thanks! I'm using Firefox 9.0.1. Solved - thanks Danny! Just in case it isn't clear from the answers and comments below: This was an issue with 2.16.1 and IMO the best solution is to upgrade to 2.17 or later.
