• Why there is so few AJAX (WEB 2.0) websites ?

  - by Frodik

  I am wondering and looking for some general reasons why there is so few full AJAX websites. Good example would be Gmail, which really uses a lot of the modern web technologies. But there is so few of these and almost all the websites use classic "request - pageload" approach. I am going to be developing website with most requests completed by AJAX call, as there is need for as few page loads as possible. So I am looking for some general advices or opinions about this. My personal big concern is search engines, because if most of the content is at one URL, how do you make that AJAX content crawlable ? There are probably more these questions which rise up, and I am looking for these to prepare for these problems before I start developing and it's too late to fix them.

• Composite pattern in C++ problem

  - by annouk

  Hello! I have to work with an application in C++ similar to a phone book: the class Agenda with an STL list of Contacts.Regarding the contacts hierarchy,there is a base-class named Contact(an abstract one),and the derived classes Friend and Acquaintance(the types of contact). These classes have,for instance, a virtual method called getName,which returns the name of the contact. Now I must implement the Composite pattern by adding another type of contact,Company(being derived from Contact),which also contains a collection of Contacts(an STL list as well),that can be either of the "leaf" type(Friends or Acquaintances),or they can be Companies as well. Therefore,Company is the Compound type. The question is: how and where can I implement an STL find_if to search the contact with a given name(via getName function or suggest me smth else) both among the "leaf"-type Contact and inside the Company collection? In other words,how do I traverse the tree in order to find possible matches there too,using an uniform function definition? I hope I was pretty clear...

• MySQL SELECT where if stores have X, show me everything that they have

  - by tnt0932

  I have a MYSQL table like this: STORES (SPID, StoreID, ProductID); And data like this: { 1 | s1 | p2 } { 2 | s1 | p7 } { 3 | s1 | p8 } { 4 | s2 | p1 } { 5 | s2 | p3 } { 6 | s2 | p6 } { 7 | s2 | p9 } { 8 | s3 | p2 } { 9 | s3 | p5 } And I would like to: Use a MYSQL SELECT query to get results, where if a store has a certain product, then a list of all of the products at that store will be returned. For example, if I were looking for "p2", then I would like to know that "s1" has "p2, p7, p8" and "s3" has "p2, p5". Please let me know if you require any more information. I'm not sure what is required to solve this issue (Which is probably why I can't search and find the answer!) Thank you.

  - by Umesha MS

  Hi, I am very new to QT UI development. I need to create a button with text should be below the icon. There is no option to set this property to the QPushButton. When I tried to search in the net, they told me to use QToolButton. When I used the QToolButton I could set the Qt::ToolButtonTextUnderIcon. But I couldn’t find a way to change the dimension i.e. Width, height, x and y position. Please help me to display a icon with text should be bellow the icon.

• Getting age from an encrypted DOB field

  - by Mailforbiz

  Hi all Due to certain compliance requirements, we have to encrypt the user DOB field in the database. We also have another requirement to be able to search a user by his age. Our DB doesn't support transparent encryption so encryption will handled by the application. Any good ideas on how to allow for searching by age? One thought is to save the YOB in a separate column in cleartext and still be able to comply to our compliance requirement. Aside from that, any other design strategy that would help? Thanks in advance!

• How can I create a profiler GUI in WPF?

  - by thehan

  I am looking to create a task profiler in WPF with an UI similar to the one of incredibuild. Eg, timed tasks appear as strips on their respective line. Have a look at: http://baoz.net/wp-content/2009/06/ib1.png to see what I mean. I am unsure what the best way to tackle this problem is? Should I override the Panel class creating a custom layout panel for this or might there be an existing control/library out there that can fit my needs. I have so far had a look at various charting controls but am unsure of weither they can be tweaked to achieve this behaviour or not. I am really hoping for someone who has been using WPF for a while to help me narrow down my search. It is not exactly easy to know what to google for either :)

• Is it possible to create a Service that listens for hardware key presses?

  - by VoteBrian

  I'd like to run an Android background service that will act as a keylistener from the home screen or when the phone is asleep. Is this possible? From semi-related examples online, I put together the following service, but get the error, "onKeyDown is undefined for the type Service" public class ServiceName extends Service { @Override public void onCreate() { //Stuff } public IBinder onBind(Intent intent) { //Stuff return null; } @Override public boolean onKeyDown(int keyCode, KeyEvent event) { if(event.getAction() == KeyEvent.ACTION_DOWN) { switch(keyCode) { case KeyEvent.KEYCODE_A: //Stuff return true; case KeyEvent.KEYCODE_B: //Stuff return true; //etc. } } return super.onKeyDown(keyCode, event); } } I realize Android defaults to the search bar when you type from the home screen, but this really is just for a very particular use. I don't really expect to distribute this. Also, it'd be nice to use the camera button to wake the phone.

• looking for RTF template system with simple DSL

  - by 01

  Is there any framework that fills up rtf document with data? The idea is to make business people/testers change the document in MsWord and than generate reports from that. The problem is with tables, Id need to create some special DSL for handling tables and showing hidding text/page parts. Id rather not do that and use some existing solution. I tried to search for something, but I only found frameworks that can produce rtf output from xml input and i want to use rtf as input and output.

• Find and sort by number of ocurrences of tag with Active Admin and act_as_taggable_on

  - by nunopolonia

  I'm using act_as_taggable_on and Active Admin on a Rails project. In that project there are Posts and each Post has Tags. I want to show a list of Tags in Active Admin and the number of ocurrences of each one. The way I found to do this was: index do column :name column :ocurrences do |tag| ocurrences = Post.tag_counts.find(tag.id).count end default_actions end Which will search the Tag List every time for every Post, which performance wise looks really bad. I would also like to be able to sort the tags by ocurrence. Any idea of how I can do it?

• Get the names of IDs from different table

  - by user896692

  I have an array with a lot of data from a database. In the array, there are two fields called teameinsid and teamzweiid. The query is a very simple one : $spiel = mysql_query("select teameinsid, teamzweiid from begegnung", $connection) or die("Keine passende Begegnung"); What I need is to search in the database for the names of these IDs. The names are in a different table. What I have now is the following: while($tmp = mysql_fetch_array($spiel)){ $teins = $tmp['teameinsid']; $tzwei = $tmp['teamzweiid']; } So I know the two IDs, but I don't know where to save the names. If I try: $name = mysql_query("select name from team where teameinsid = $teins", $con) it gets overwritten every time. How can I manage this?

• [Raise|Trigger|Fire|...] an event?!?

  - by winSharp93

  Hello, in a German programming forum we currently have a discussion about events and what you (grammatically) do with them. The MSDN talks about "Event Raising" and "to raise an event". Thus, this seems to be one possibility. Are there any other synonyms? What about "to trigger an event" and "to fire an event"? A Google search will bring results for all of the three possibilities. This, however, does not mean that they are correct, too, of course. Are they? Are there any (stylistic, ...) differences or are they used in different contexts? Many thanks in advance for ending a heated debate :-)

• How do I .MatchCase and .WholeWord?

  - by Tanner

• WP: redirect users to a certain category using cookies

  - by kass

  Basically like cragslist. once you select city on craigslist, nexttime when you go to the site, it redirects you to the city you selected. What I want to achieve: When a person comes to the site and selects a particular category, the next time they come to the site (returning user) - the page will open up on that category section. I would think this would be fairly easy to do via setting a cookie when the visitor clicks on the category link (or when the category page loads). When they return the following time, the cookie is read and then the page redirects accordingly. Unfortunately my knowledge of PHP and cookies is limited, (hence my search for answers) so I need to ask if anyone can help me out! Anyone have any ideas? Thanks!

• TCP Scanner Python MultiThreaded

  - by user1473508

  I'm trying to build a small tcp scanner for a netmask. The code is as follow: import socket,sys,re,struct from socket import * host = sys.argv[1] def RunScanner(host): s = socket(AF_INET, SOCK_STREAM) s.connect((host,80)) s.settimeout(0.1) String = "GET / HTTP/1.0" s.send(String) data = s.recv(1024) if data: print "host: %s have port 80 open"%(host) Slash = re.search("/", str(host)) if Slash : netR,_,Wholemask = host.partition('/') Wholemask = int(Wholemask) netR = struct.unpack("!L",inet_aton(netR))[0] for host in (inet_ntoa(struct.pack("!L", netR+n)) for n in range(0, 1<<32-Wholemask)): try: print "Doing host",host RunScanner(host) except: pass else: RunScanner(host) To launch : python script.py 10.50.23.0/24 The problem I'm having is that even with a ridiculous low settimeout value set, it takes ages to cover the 255 ip addresses since most of them are not assigned to a machine. How can i make a way faster scanner that wont get stuck if the port is close.MultiThreading ? Thanks !

• Small questions on data structure

  - by John Graveston

  Hi, I'm trying to search the parent of a node with Kruskal's algorithm. My program works just fine, but I think I have heard of a method to improve the speed of the algorithm by reconstructing the tree while searching for the parent node and connecting it to the parent node. I'm pretty sure that I've heard of this somewhere, maybe in a lecture. Can anyone refresh my memory? And also, given a number of arrays, when searching for the minimum and the maximum value from a certain section of an array, what is the name of the tree that can calculate the minimum/maximum value from the array by making a binary tree that has the minimum/maximum value of each array in O(log N)?

• Avaliable parallel technologies in .Net

  - by David

  I am new to .Net platform. I did a search and found that there are several ways to do parallel computing in .Net: Parallel task in Task Parallel Library, which is .Net 3.5. PLINQ, .Net 4.0 Asynchounous Programming, .Net 2.0, (async is mainly used to do I/O heavy tasks, F# has a concise syntax supporting this). I list this because in Mono, there seem to be no TPL or PLINQ. Thus if I need to write cross platform parallel programs, I can use async. .Net threads. No version limitation. Could you give some short comments on these or add more methods in this list? Thanks.

• Searching for URL's Relative to Site Root in Javascript Source

  - by James

  Hi, I am working on a web site with several other developers and we have had problems where people commit JavaScript code with AJAX calls that use URL's relative to the site root. An example would be /Home/Index which will not work if the site is hosted in a virtual directory. To get round the problem we use a $.url() method to convert it to a full path, e.g. $("#container").load($.url("/Home/Index")) I am trying to write a unit test that will search each JavaScript file and find places where the $.url method is not being used. The only problem is that I cannot seem to write a regex expression to do this. I have tried the following: (?!\$\.url\()"(/\w*)+" But this does not work. I cannot find a way to say that I don't want the $.url in front. Does anyone know if this is possible? Note that I need regular expressions that are compatible with .NET Thanks.

• How do I make a DIV stay at the top of the screen no matter ow far down the page my visitor scrolls?

  - by user1289863

  What I'm saying is, I have some extremely long pages on my website, which can make it annoying I've my visitors need to scroll to the top of the page to be able to navigate to another page. I'm not quite sure what I would call this but any Google search that contains the words 'DIV' and 'float' come up with completely unrelated results... What I'm looking to do is create a DIV that stays at the top of the Screen (not to be confused with the page) so that if the user is at the bottom of the page, they can still see the navigation bar just floating at the top of the screen. What I can think of is to position the DIV relative to the position of the screen but I don't know how to code this. I'm happy to use JavaScript (preferably in the form of jQuery), but if you know how to do this using CSS, I would favour your response. This might help: I know a little bit of jQuery and JavaScript and I know a good deal of CSS and HTML. Thanks in advance.

• finding character in string C language

  - by iSight

  Hi, I am searching a character at first occurence in string using the following code. But, it is taking some time when the character is too long or the character that i am searching is at far extend, which makes delay in other operations. How could i tackle with this problem. The code is below here. Note: attrPtr is a char* which holds a reference to a string containing '"' character at far extend. int position = 0; char qolon = '"';//character to search while (*(attrPtr + position++) != qolon); char* attrValue = NULL; attrValue = (char*)malloc(position * sizeof(char)); strncpy(attrValue, attrPtr, position-1);

• Is there a way to automatically grab all the elements on the page using Selenium?

  - by VGambit

  When creating tests for .Net applications, I can use the White library to find all elements of a given type. I can then write these elements to an Xml file, so they can be referenced and used for GUI tests. This is much faster than manually recording each individual element's info, so I would like to do the same for web applications using Selenium. I haven't been able to find any info on this yet. I would like to be able to search for every element of a given type and save its information (location/XPath, value, and label) so I can write it to a text file later.

• Seek a jQuery-based inplace HTML editor

  I just stepped over to http://plugins.jquery.com/search/node/editor - lots and lots of choices - and if to judge by the dates, many new offerings. I'm hoping someone can help me narrow down the field according to these priorities... Stability & Well-formed XHTML (might argue against some of the most recent unless they are revisions with a clear track-record) Inplace editing Good AJAX integration For internal / admin / CMS usage so it can be as bloated as it needs to be long as it's easy to implement the basics: bold ital indents lists No need for tables but dropdowns that show relevent CSS selectors would be nice. thnkx
