• Append before parent after getSelection()

  - by sanceray3

  Hi all, I have one question. I try to develop a little WYSIWYG editor. I would like create a <h1> button which allows me to generate a <h1> title (by clicking on button after text selection in <p> element). I obtain the selection with window.getSelection().... But now, I would like to put my append("<h1>my text selected</h1>") just before the <p>. It’s my problem, because my <p> elements don’t have id or class. So do you know a means to put my append just before the <p> where my text has been selected? I don’t know if with my bad English you’ll understand me! Thanks very much for your help.

• Which DB Server should I use?

  - by Alex

  I have to develop a new (desktop) app for a small business. This business currently has an Access database with millions of records. The file size is about 1.5 GB. The boss told me that searching on this DB is very slow. The DB consists of a single table with about 20 fields. I also think the overall DB design isn't great. I thought to use another DB server with a new design to improve both performance and efficiency. Considering this is a relatively small business, I don't want to spend much for a DB license, so I want to ask you what would you do. Continue to use Access, maybe improving and optimizing the DB in some way Buy a DB server license (in this case, which one?) ? (any idea?)

• Validate authenticity of website owner

  - by Cyber Junkie

  Hello all! I'm planning to develop a web app where users will list their site/blog. When people submit their sites, how can I confirm that they are the owners of it? So for instance there is a user Mark who wants to submit someone else's website without their approval. I want to restrict Mark from doing so unless he is the actual owner. My idea was to do a comparison between the user's email domain and the website domain she/he wants to submit. If they match allow the user to submit the website. However most people don't register with their website domain address.. or perhaps I'll implement a Facebook connect in the future. What other methods would you suggest?

• [C++] Start a thread using a method pointer

  - by Michael

  Hi ! I'm trying to develop a thread abstraction (POSIX thread and thread from the Windows API), and I would very much like it to be able to start them with a method pointer, and not a function pointer. What I would like to do is an abstraction of thread being a class with a pure virtual method "runThread", which would be implanted in the future threaded class. I don't know yet about the Windows thread, but to start a POSIX thread, you need a function pointer, and not a method pointer. And I can't manage to find a way to associate a method with an instance so it could work as a function. I probably just can't find the keywords (and I've been searching a lot), I think it's pretty much what Boost::Bind() does, so it must exist. Can you help me ?

• JButtons don't imediatly change on mouse event

  - by out_sider

  I'm using the java swing library to develop a board game called DAO. The problem is that after the human player makes its move, by clicking on the JButton with the piece image that he wants to play, I call the computer AI routine but inside the mouse event function. By doing this only when the function returns, the computer ends its turn, do the JButtons refresh their Images (setIcon comes in). I'd like to know how can I force the JButtons to change their image at the moment they are clicked and not only when the mouse event function ends (as I need to handle data inside it). I've tried all of this myButtons[i][j].setIcon(xIcon); myButtons[i][j].revalidate(); myButtons[i][j].repaint(); myButtons[i][j].validate(); None worked. Thx in advance

• Metro style apps with Html and C#

  - by labroo

  According to this slide http://geekswithblogs.net/images/geekswithblogs_net/technetbytes/windows-8-platform-tools.jpg Does it mean I have to use XAML view with C# if I want to develop a metro styled application? Can I use a HTML/JS/CSS - C# combination with event handlers and all? Something like ASP.NET Webforms/MVC . I know it is not the same client server architecture, but since metro styled apps support HTML/JS, I was wondering. I can use Win-JS. But can I rather write C# than Javascript, and use HTML rather than XAML?(I dont know XAML and I like C#) All the C# samples I found online use XAML.

• level of control of the os on the phone hardware

  - by gurnisht

  Hello. I am new to Android and mobile phones development. I want to develop an application that needs to have a total control over the "phone" of the smartphone, i.e. controlling all the communication of the GSM chip with the cellular system, accessing the SIM card identity that it sends (encrypted) to the cellular system, disabling the cellular antenna and resuming it back, and more of that kind... Can it be done with Android? Does the software (OS) have control over all of the phone components in a smartphone, or there are some parts that are done in the hardware level only? (I guess that the Android API won't enable me to do everything i want, but even theoretically is it possible if I recompile the OS after making the changes there?) Thanks!

• Choosing an alternative ( visual basic) high level programming language

  - by user370244

  I used to be visual basic 6 programmer, i was pleased with visual basic : it is high level language that do stuff fast,easy to learn, easy to do stuff in,you can drag and drop stuff to the form and write your code,it is simply amazing.however microsoft buried VB6 and pointed us to VB.NET which is so different that it is not the old VB anymore.I didn't like what microsoft did and would like to look somewhere AWAY from microsoft and from any other proprietary language . I would like to look into a similar language that is easy,cross platform (windows / Linux), object oriented, visual design, non proprietary and compile (for some guarding against reverse engineering). i am freelancer so the choice is entirely mine,i don't care about performance of programs, the time taken to develop a given programs is much more important. desktop / database / GUI /networking programming is what i am looking for. so any such language offered by our open source community ? thank you so much

• Shift from Java to c++

  - by zengr

  Hello, I have been developing applications based on C# (.net) and Java (J2EE) from the last 3 years. But, now I feel, Java, C# makes you lame (from learning point of view) and you can develop your apps quickly but you fail to understand the basic underlying concepts of programming. So, I am trying to learn C++, but I find it a little "confusing" due to pointer, multiple inheritance, some conventions and other concepts of C++ which don't exist in Java. So, what do you guys suggest? How should I got about it? Thanks PS: I am a student, so have all the time in the world and actually shift.

• localhost/live - detect by HTTP_HOST

  - by Adam Kiss

  Hello, let's say I develop locally and debug small things on live server. Is it good idea to have something like this in my code? : $is_local = (strpos($_SERVER['http_host'], 'localhost') !== false); define ('DEBUG',$is_local); And then use it through my code, when setting stuff? $mysql_settings = (DEBUG) ? array(/*localhost settings*/) : array(/*live settings*/); This way, I can use the same files live and on localhost, so I can sync without any fear of having wrong e.g. connection settings on live server. Is it good or wrong idea?

• Creating a Linux Desktop Envoriment

  - by Alon

  Suppose I want to create my own desktop envoriment for Linux, without X. Like Google with the Android did. Where do I start? Is it actually a normal application that just draws stuff, and starts after the kernel boot? And how does it draw it? Using OpenGL or is there something more generic? And graphics drivers, how is it going? You should develop custom graphics drivers for your desktop or it comes with the Linux kernel? Note: It's for normal PCs and not embedded devices. Thanks.

• Video/ Speech Development of Applications

  - by idea_

  Why do we continue to type and click away in IDEs when we could theoretically use hand gestures and speech to develop applications? Think about it - Developing a class by standing in-front of your computer, making some gesture, and yelling "CAR!". This doesn't have to strictly apply to OOP either. We have sufficient speech and image acquisition/ processing and analysis tools available to us, don't we? This seems plausible to me, but I may be overly ambitious. From a conceptual point-of-view, do you see any problems with the implementation?

• Time for creation of database on site

  - by slo2ols

  Hi. When and where would you create database to develop web site using ASP.NET MVC 2 and Entity Framework 4 (CreateDatabase method). I think about first run of web site and redirect on welcome page, when controller creates database from model. But I doubt about details: 1. Where? In HttpModule, but request of any image or css will check that database exist. In custom RouteHandler, but then anybody need to know that need to use this handler when to add route. In BaseController, but then code will look like SomeController(..., IDatabase database) : base(database). 2. When? Better create database on first run by any url or may be on deployment of site (additional tool which create ObjectContext and invoke CreateDatabase)? Thanks.

• PHP / XHTML. Should I place everything in echo tags?

  - by 110175914651386975417

  A quick question involving PHP development, I seem to be wondering about this more and more as I develop more complex sites. Basically say we have a basic PHP / XHTML inbox (messaging system). I perform checks at the top (check if user is logged in, check if user has correct permissions etc). Then use the 'header('location:www.abc.com)' function if the authentication fails. The question is do I write the rest of the inbox code in a huge 'else' block or just use standard html. I read somewhere about about it being bad to put any code after using the 'header' function.

• "Teach" a computer how to do addition?

  - by ffar

  The problem is to learn computer to do addition. Computer have as input a knowladge of a numbers: he "knows" that after 1 goes 2, after 2 goes 3 and so on... Having that data computer can easyly get next number. Next, computer have knowlandge as input that x+0=x and x+(y+1)=(x+1)+y. This axioms let computer to do addition. For example, to add 5 and 3, computer makes following: 5+3 = 5+(2+1) = (5+1)+2 = 6+2 = 6+(1+1) = (6+1)+1 = 7+1 = 8. But this is too long to add numbers in such way. The problem is to develop program which can improve this way of addition using the rules of mathemetics and logic. The goal addition must executed in O(log(N)) time, not O(N) time, N is magnitude of added numbers. Have this program any science value? Is any program can do such things?

• If you could remove one feature of php to help newbies what would it be?

  - by Chris

  If you could remove one feature from PHP so as to discourage, prevent or otherwise help stop newer programmers develop bad habits or practices, or, to stop them falling into traps that might hinder their development skills what would it be and why? Now, before the votes to close it's not as open-ended as you might think. I'm not asking purely what is the worst feature or what feature would you really like to remove purely arbitrarily. Yes, there may not be one correct answer but I suspect there will be many similar answers which will provide me with a good idea of things I might be doing wrong, even inadvertently.

• How does android communicate with dynamic services?

  - by ezekielweb

  I am trying to develop an app and I want it to bring in data from a mySQL database. But from some reading I have done on different sites, I am realizing that it is probably not going to happen. But I am curious to know, how do apps like PhoneFlix and others view that dynamic data on the application? Does it somehow just bring it in through http? If so, how would I go about doing that? Does anyone know of any good sites that will point me in the right direction? Thanks ezekielweb

• Is there an off the shelf CMS that can be used as a back end for smartphone travel guide apps?

  - by eamonncarey

  I'm wondering if there's an off the shelf CMS available that is similar to something like Mobile Roadie - ie: it will allow you to create multiple versions of one application? I'm looking to develop some mobile travel guides for iPhone/Android/Blackberry etc, and rather than get a CMS built, I'd like to see if there's something out there is similar to Wordpress in that it will allow us to input text, images, Google Maps details, phone numbers, email addresses and potentially some audio/video content. If anyone knows of anything, I'd love to hear about it. Also, if you have any ideas regarding pricing, that would be extremely helpful! Thanks in advance for your assistance.

• Create proxy to Java app so it can work on the iPhone? [closed]

  - by Kovu

  okay guys, these are the facts: I have a java chat. I can NOT have any develop-revelant information. So this all is static. It's not my chat. So fact 2: IPad does not have Java and it will not have it in future. So now, the very hard task: bring this both together. My idea: Develope a proxy server for this. 1) The data from the IPad will send to a server. 2) the server recieve data and call the JRE and the complete chat-client 3) The server gets the "chat" himself and send it back to the Ipad Is that and possible idea or bad? Did I oversee something? Anyone have a idea where to start?

• Call java program on server through web request

  - by Rossella

  I need to develop an application where a Java client calls a Java application located on the server with certain parameters, the Java application on the server computes data and sends the data back to the client. Everything needs to go through port 80 on which I have a IIS webserver listening. I cannot open any other port on the server. Is there any way I can do this? The server can write files in a directory that the client can read but I am not sure how to handle the synchronization and I don't know how to call a script on the server from the client through port 80. Every suggestion would be highly appreciated Thanks a lot in advance, this problem is making me crazy
