  • How to count the letters in a text with Javascript?

    - by Doguhanca
    I am currently trying to write a ''web application'' that has a simple text area inside, in which I want the letters of the text written to be pointed out. For example, if I write: ''How old are you? I am 19 years old'' I need a code to tell me how many 'A's and 'Y's and 'D's (and all letters of the alphabet from 0-26) are used in this sentence when I press a button on a HTML/ CSS page. Could you please tell me what I must write into my .JS file and what I should write into my .HTML file to do this with a click of a button when something is written in the ? I hope my explanation was detailed enough. Thanks! Edit (I'm very sorry for the problems I caused) - What I have done so far looks like this: HTML: <link rel="stylesheet" type="text/css" href="theme.css"> <meta charset="utf-8"> <script src="test.js" type="text/javascript"></script> <div class='header'> Al.Fa.Be </div> <div class='yaz'> <textarea></textarea> </div> <div class='description'> <a href='http://www.google.com'>Ara</a> </div> <div class='description2'> <input id="clickMe" type="button" value="Hesapla" onclick="doFunction();" /> </div> CSS: body{ background:white; } selection{ background:#CCC; } #clickMe{ background:#CCC; border:1px solid #333; } .header{ font-size:70px; font-weight:bold; font-family:Arial; color:#333; margin-left:580px; padding-top:200px; } textarea{ width:1210px; height:40px; color:black; margin-top:20px; margin-left:100px; padding-left:10px; padding-top:10px; font-size:18px; font-family:Arial; } .description{ background:#f2f2f2; padding:6px; width:50px; text-align:center; border:1px solid #ddd; font-family:Arial; margin-left:620px; margin-top:20px; font-size:14px; } .description a{ color:#555; text-decoration:none; } .description2{ background:#f2f2f2; padding:6px; width:60px; text-align:center; border:1px solid #ddd; font-family:Arial; margin-left:750px; margin-top:-30px; font-size:14px; } .description2 a{ color:#555; text-decoration:none; } .yaz{ color:white; } Javascript: // Input name. Count number of alphabets a-z class program                                                          {     public static void main(String[] args)     {         String name = args[0];         int count[] = new int[29];         int i,p;         int n = name.length();         name = name.toUpperCase();         char c;         for (i=0; i<29; i++)         {             count[i] = 0;           }         for (i=0; i<n; i++)         {             c = name.charAt(i);             p = (int) c;             count[p-65]++;         }         for (i=0; i<29 ; i++)         {             if (count[i] >0)             {                 System.out.println((char)(i+65) + " occurs " + count[i] + " times");             }         }     } }

  • mod_rewrite to change my urls

    - by user319859
    Hi, I've been fighting with mod-rewrite for a while. Basically, I have a website that I'm moving to a difference namespace/directory. What I'd like to do is change urls that look like this: http://mydomain.com/index.php?a=xxxxxxxxxx These urls will always have "index.php?a=". I have a different/new site that also has an index.php file, so it's important that I do a rewrite only when a= is in the URL. The new url should be like http://mydomain.com/ns1/index.php?a=xxxxxxxxxxx Seems pretty simple, but i can't seem to get mod_rewrite to do it for me, here's what I have: # rewrite old urls to new namespace RewriteRule ^/index.php\?a=(.*)$ /gc1/index.php\?x=1&a=$1 [R=301,L] See anything wrong?

  • MySQL Import Database Error because of Extended Inserts

    - by Castgame
    Hello all, I'm importing a 400MB(uncompressed) MySQL database. I'm using BIGDUMP, and I am getting this error: Stopped at the line 387. At this place the current query includes more than 300 dump lines. That can happen if your dump file was created by some tool which doesn't place a semicolon followed by a linebreak at the end of each query, or if your dump contains extended inserts. Please read the BigDump FAQs for more infos. I believe the file does contain Extended Inserts, however I have no way to regenerate the database as it has been deleted from the old server. How can I import this database or convert it to be imported? Thanks for any help. Best Nick EDIT: It appears the only viable answer is to separate the extended inserts, but I still need help figuring out how to split the file as the answer below suggests. Please help. Thank you.

  • What traits can hint a teenager he should pursue software development career?

    - by sharptooth
    We're gonna have a day when employees' kids will visit our company office. The idea is that they will come see "how parents work", "how cool stuff is done", have fun, etc. Kids will be up to 17 years old. Now I suppose some of the teenagers already think of what they wanna do when they finally grow up and will ask questions like "how can I tell I should get a degree in software engineering and not in logistics/finances/whatever?" So I think we better be prepared and ready to answer those questions so that those who really fit don't waste time but use their potential to the full. What traits that already emerge in teenage years indicate that a person could become a very good software developer?

  • Project hosting on Google Code. Files are cahced?

    - by Frexuz
    I do not really understand how Google Code handles file versioning. I am building a jQuery plugin that anyone can access. Like so: <script type="text/javascript" src="http://jquery-old-browser-warning.googlecode.com/files/jquery.browser-warning.js"></script> This script accesses other files on the same project (via ajax). The problem is, that when I upload a new file, it just seems like there aren't any changed to it. Google recommends that new files should have new names. But then I would have to change the filenames that the script loads. But then I would have to change the script file as well, and that would break everybodys implementation (with the script-tag above) Is there a way to force a file to change when uploading with the same filename? PS: If I go directly to the project page's file list. Then I do get the file with the updated content. But as I said, not when getting it through ajax.

  • How do I change careers to become a programmer without spending a lot of money

    - by bgc83
    I'm currently a network engineer, but find myself wanting to get into the world of development. I took a little bit of Java in college, am 27 years old and have been network engineering for 4 years now. I have a mortgage and student loans so going back to school would be difficult. I'm willing to put in however much hardwork is needed around my full time job to learn, but part of me feels I may need actuall schooling to get down some of the advanced concepts. Just looking for a little advice and direction. I have purchased a bunch of the Head First programming books and have begun reading through some of them as I figure out my way into this transition.

  • As a Web Developer, how complicated is your average job? [closed]

    - by Daniel S
    Hey people, I'm 16 years old and I've recently started to do freelance jobs. I've been playing with PHP since I was 12 and I think that I can code reasonably well. So far, I've created a library for fetching info from LinkedIn profiles and some Wordpress plugins. Right now this client wants me to convert an HTML template into a Wordpress theme for using as a website. I feel this is a tad easy, so I wanted to ask, as professional web programmers, are most assignments harder than this?

  • When is it useful to define your own delegates instead of using the generics?

    - by Carlos
    I've been going through some old code, where I came across some custom defined delegates, which are used thus: private delegate void ListenDelegate(UdpClient listener, bool multicast); private void ListenOn(UdpClient listener, bool multicast) { new ListenDelegate(_ListenLoop).BeginInvoke(listener, multicast, null, null); } With some of the new .NET framework versions, you can do the following: private void ListenOn(UdpClient listener, bool multicast) { new Action<UdpClient, bool>(_ListenLoop).BeginInvoke(listener, multicast, null, null); } This ought to be exactly the same. Is there any point in defining your own delegates, when the generic delegates seem to do the same job with less space? Or have I missed something about the generics that makes them not equivalent?

  • How to copy QT folder to another folder without reinstalling it?

    - by Oleg
    I have QT installed on disc D (on Windows). And I want to move it to disc C. Is it possible to do that? If I just copy QT folder from C to D then I see lot of errors when I compile my applications that use QT. Errors are because qmake.exe contains full paths to include, bin and libs folders inside. So, when I create solution for Visual Studio 2005 using qmake - then this solution contains dependencies to old QT folder from disc D. And I found no way how to remove this dependencies without reinstalling of QT. It is not a big problem for one my single machine - I can reinstall. But I need to deliver this change then to tens and hundreds of other developers machines and I want to make it as easy as possible without need to reinstall QT.

  • Is a PHP-only "cache engine" ever worth it?

    - by adsads
    I wrote a rather small skeleton for my web apps and thought that I would also add a small cache for it. It is rather simple: If the current page exists as a file in the cache and the file isn't too old, read it out and exit instead of rebuilding the page If the current page isn't cached/outdated recalc the page and save it However, the bad thing about it is: My performance tests with a page that receives 40 relatively long posts via a MySQL query said that with using the cache, it took even longer to handle a single request (1000 tests each) How can that happen? Should I just remove the complete raw-PHP cache and relieve on the availability of some PHP cache like memcached or so?

  • Port a Rails App from Windows to Mac

    - by Ryan Max
    Hello I've been a Rails developer on Windows for quite some time now, but I recently completed my biggest project yet (it's quite extensive, took me over a year to build) but I am having trouble deploying it. The combination of it's size, complexity and a windows environment is making it needlessly complex to deploy. I am thinking about getting an old mac mini and using it just for rails development. Is there any way I can port my app to this mac, without having to start over? I can't find any resources on the internets about this.

  • SharePoint 2010 GAC deployment doesn't update

    - by mcnarya
    The following issue just crept up on me. The steps mentioned below had worked just fine until about 2 days ago. When I deploy a update to a solution (of web parts) to a SharePoint 2010 server I don't see the update. The solution does get installed, but from what I can tell the installed web parts are over a month old (nothing new is installed). I do the following steps through PowerShell: retract the solution from the web app remove the solution add the solution install the solution to the web app I have tried restarting the Web App, restarting IIS and also restarting the server. Nothing seems to work. I notice that after I remove the solution it does get removed from the GAC. After I add/install it the solution does reappears in the GAC. Am I missing something? Am I overlooking a step that I should be doing? Something to try?

  • jQuery UI .widgets resetting scroll positions of elements contained within

    - by Derek Adair
    I am making heavy use of jQuery UI with my latest project. Unfortunately I've hit a major wall due to some really whacky behavior exhibited by the jQuery UI widgets when they contain elements with scrollbars for overflow. Check out this demo Scroll down in one of the .scroll-container elements Click an accordion header Click on old header - note the element was auto-scrolled to the top. Is there anyway to prevent this from happening? It's screwing with a major plugin of mine that utilizes jQuery scrolling. I'm flat-out lost as to what to do here! Perhaps this is a bug worth mentioning in the jQuery UI dev forums... EDIT I am using Chrome - 8.0.552.231 and OSX 10.6.5

  • Confusion with cookie session token and oauth2.0 don't know where to go anymore

    - by byte_slave
    Hi guys, I'm completely confused, frustrated and nothing seems to make sense and work any more. I' dev some iframe fb app and i've been using the javascript sdk (FB.Init()) to get the access_token, but doesn't always work, sometimes i'm already logged into FB and doesn't works... Did some reading, and read also that there is problems using cookies in iframes in Opera and IE, so I was thinking in use the OAuth 2.0 but i'm not sure how via facebook sdk c# and now I'm now completely lost, don't know if i still need to use the javascript FB.Init(). Documentation out there is poor and unclear, a lot of stuff refers to old code, and after hours of reading, jumping on examples, i'm completely messed up and confused. Can some, please, point/explain/enlightening me about this? Thanks a lot guys, appreciated! Merry christmas!

  • Linux shell to restrict sftp users to their home directories?

    - by hfidgen
    I need to give SFTP access to a directory within my webroot on my server. I've set up ben_files as a user and have set his/her home directory to /var/www/vhosts/mydomain.com/files That's all fine if he/she connects with plain old FTP - he's/she's restricted just to that directory, but to enable SFTP I had to add him/her to bin/bash shell, which suddenly opens up my entire server... Is there a way of giving him/her SFTP access but without opening up all my directories? I'd really like him restricted to only his/her home ;)

  • Modal windows plugin to rails

    - by VP
    Hi, I'm starting to digg some rails plugins to create modal forms in rails. Almost all documents that you find are too old (2006,2007) or more focused in php. I would like to create a "feedback" tab that when you click on that, it opens a form. For example, you can check the railscast website, http://railscasts.com/. Ryan Bates made it in his website, but didnt make any screencast about it. any idea/tip about a rails plugin to work with jquery and to do those forms?

  • Getter/Setter from separate class file in Java

    - by Crystal
    I'm new to Java and for a HW assignment, we had to create a Person class that has a constructor, getter/setter for the attributes of firstName, lastName, phone. That is in a separate file from an old HW assignment (Person.java). Now we have to use that Person class in our new HW assignment (LoanApplication.java). So if one of the attributes is private Person client do I need to create getter/setters or a constructor again? Otherwise, how does each LoanApplicaiton instance know which Person attribute it is to go with? How does the JVM know that it can use the Person.class even though my LoanApplicaiton.class does not extend Person.class? Thanks.

  • Long/compound namespaces when using C++/CLI

    - by biozinc
    I'm working on a project where a mixture of C# (95%) and C++/CLI (5%) are used. The namespace naming convention I'm aiming for is the good old Company.Technology.Etc.. This works perfectly fine for C#. Now, can I carry this across to C++ classes? I read here that compound namespaces aren't supported in C++. Am I stuck with the clumsy namespace Company { namespace Technology { namespace Etc { ... } } } in order to stay consistent? Is it worth trying to stay consistent?

  • How to tell a UITableView to preload all Rows?

    - by Infinite
    Is there a way to tell a UITableView to preload all rows? The tableView is supposed to show several comments (up to 80 comments). So my CommentCell uses a Setter to adapt the cell to a specific comment. -(void)setComment:(Comment *)newComment { if (newComment != comment) { [comment release]; comment = [newComment retain]; /* * set the cells view variables here */ } } This specific setter takes quite a bunch of processing resources and scrolling gets kinda laggy. I am using a comment-specific reuseIdentifier instead of a static cellIdentifier when calling dequeueReusableCellWithIdentifier: in order to assure, that "newComment" equals the old "comment". And in fact this does work great when scrolling over cells which have already been loaded. But when scrolling through the comments for the first time, it still lags like hell. Which leads me to my question: Is there a way to tell the tableview to preload all cells? (which I doubt) or Do I have to implement my own cache instead of relying on "dequeueReusableCellWithIdentifier:"?

  • How do you resolve the common collsision between type name and object name?

    - by Catskul
    Since the convention is to capitalize the first letter of public properties, the old c++ convention of initial capital for type names, and initial lowercase for non-type names does not prevent the classic name collision class FooManager { public BarManager BarManager { get; set; } // Feels very wrong. // Recommended naming convention? public int DoIt() { return Foo.Blarb + Foo.StaticBlarb; // 1st and 2nd Foo are two // different symbols } } class BarManager { public int Blarb { get; set; } public static int StaticBlarb { get; set; } } It seems to compile, but feels so wrong. Is there a recommend naming convention to avoid this?

  • Javascript: Access the right scope "under" apply(...)

    - by Chau
    This is a very old problem, but I cannot seem to get my head around the other solutions presented here. I have an object function ObjA() { var a = 1; this.methodA = function() { alert(a); } } which is instantiated like var myObjA = new ObjA(); Later on, I assign my methodA as a handler function in an external Javascript Framework, which invokes it using the apply(...) method. When the external framework executes my methodA, this belongs to the framework function invoking my method. Since I cannot change how my method is called, how do I regain access to the private variable a? My research tells me, that closures might be what I'm looking for.

  • Get rid of all user data of Android application after bigger update

    - by Johe Green
    Hi, I completely revamped an app. Tested it for a while on my device and emulator. The app worked fine. However when I updated the app through the Android market, my users experienced crashes. Since there is no way to properly debug this procedure I asume the crash is caused by old data which is not being removed from the device (probably from the onsavedstate bundle?!). Is there a way to do a "clean/total" reinstall without having the user to do it manually? Best Regards Johe

  • How to add "loading" screen for UIWebView app each time new page is being loaded?

    - by AragornSG
    I have an app that works with tabs and webview. I already have it setup to refresh the page assigned to a tab each time the item on tabbar is selected. My problem now is that it takes some time to load the page and it's impossible to say if the page being displayed is the old or refreshed one. What I want to do is add a "loading" screen (a simple image) which will be displayed until the refreshed page is loaded. Here is the function I run on each tab tap: - (void) goToPage:(NSString *)sid { NSString *newURL = [NSString stringWithFormat:@"%@/mykingdom.php?sid=%@", appURL, sid]; [secondView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:newURL]]]; } Thanks!

  • Does Google appengine cache external requests?

    - by Andy Hume
    I have a very simple application running on appengine that requests a web page every five minutes and parses for a specific piece of data. Everything works fine except that the response I get back from the external request (using urllib2) doesn't reflect the latest changes to the page. Sometimes it takes a few minutes to get the latest, sometimes over an hour. Is there a transparent layer of caching that appengine puts in place? Or is there something else I am missing here? I've looked at the caching headers of the requested page and there is no Expires or LastModified's sent. Update: Sometimes, it will get the new version of the page for a number of requests and then randomly later get an old out of date version.
