• PHP Guideline required

  - by user160820

  I am interested in learning PHP, but the books that I read are in procedural style and the source code that I try to reay are also mixtures of SQL,PHP and HTML. My Background is from Java. What I want to learn is PHP really with seprate Layers. Database Layer, Controller and View but I don't want to use any Framework. I also have fried some OOP PHP books, but they not what I am lloking for. What I need is a book or any Document that develops a sample website in pure PHP but in OOP style. Any Help. Thanks a lot in advance.

• send commands to a backgrounded jobs stdin

  - by dpcd

  I have a java server application that, when its running, you can interact with it sending commands via stdin. I want to write a web interface that can send these commands to it. In order to do that I need some way of getting commands from php to the stdin for this backgrounded job. Is there a way to do this from console? or possibly write some kind of wrapper that controls the server job and can access its stdin ? could this be done in python?

• How can you check if a file exists before including/importing it in JSP?

  - by codeninja

  Assuming that requestScope.importMe is expecting a path to a jsp file <c:choose> <c:when test="${!empty requestScope.importMe && fileExists(requestScope.importMe) }"> <c:import url="${requestScope.importMe}" /> ... How can I check if the file exists before trying to include it so that an error is not thrown? I'd like to avoid using inline Java. Something using one of the JSTL tags is the preferred approach.

• A strange issue... No code changes getting reflected.

  - by sachin

  I am using netbeans to develop an applet, i have a piece of code which looked like this: ipAddresss = DEFAULT_IP; System.out.println("portlet.services.hostname:" + ipAddresss); Now I changed it to something like this: ipAddresss = DEFAULT_IP; System.out.println("portlet.services.hostname using default IP Address:" + ipAddresss); But no matter what I do, it sill keep on printing: portlet.services.hostname:null I have tried deleting all .netbeans folder from documents and settings, tried creating new project, but now i am completely baffled by this issue... So, the problem is, no matter what I do, no change is getting reflected when I run the program. Can there be a java applet cache, netbeans cache, i am not sure why...

• Unable to import example projects from book (newbie question)

  - by StayWett

  I am trying to import projects from a book "Beginning Android 2" but when I choose the root directory the "Finish" button is still grayed out. I've tried importing the project from scratch with no success, and I've also tried to create a template project with the same name and everything and then importing into that (Import existing projects into workspace) but it always says "No projects are found to import". The contents of the folder are: Res folder, src folder with .java file, the manifest, build, and default.properties files. I am new to android dev (obviously) so I appreciate the help.

• How to access device settings on a S60 symbian based mobile phone?

  - by TheRHCP

  Hello everyone, I recently bought a Sony Ericsson mobile phone which embeds Symbian S60 and I would like to add a missing feature myself. In fact I cannot actually disable Internet connection in an easy way when roaming, which cost me a lot of money last time I moved away ... So I would like to develop a little application that would just replace the actual Internet configuration with a fake configuration to avoid auto-connections. So what I would like to know is how can I access programmatically to my phone settings? I believe that this is possible but I do not really have a clue where to start. I know that Sony Ericsson provides a SDK to run Java applications on its customised JVM but Symbian is also providing a SDK to develop applications for S60 devices in many languages. The real questions is which SDK will provide an API able to access phone settings. This is not well documented so I am asking this question with the hope that someone here already had experience with development for Sony Ericsson/Symbian devices. Thanks.

• Why are configuration arrays acceptible parameters in PHP and Javascript?

  - by RenderIn

  In most other OO languages it would be sacrilege to have each function receive a single associative array of Objects rather than enumerating each in the method signature. Why is it acceptable and commonly used in most popular frameworks for both of these languages to do this? Is there some justification beyond wishing to have concise method signatures? I do see a benefit in this -- that the API could remain unchanged as new, optional parameters are added. But Javascript and PHP already allow for optional parameters in their method signatures. If anything, it seems like Java or another OO language would benefit from this more... and yet I rarely see this pattern there. What gives?

• TXT file not showing properly in Android

  - by narkelion

  I developed an app for Android, that loads some data from some .txt files I created. Until now, everything went fine. Today I updated these texts to add some stuff, and now Android comes out with this error in the LogCat: 06-06 23:16:03.925: W/System.err(7999): java.lang.NumberFormatException: Invalid int: "?72" It never happened before. If I read the txt from my computer, I can see that all seems in the right place. But if I read it from the Android editor, I see strange symbols (close to that 72). I don't know how to remove them, because I cannot see them on the pc!

• What language should I learn to make 2D turn-based video games?

  - by giggles

  I want to make 2 dimensional turn-based games for the PC. Something like early Final Fantasy or Chrono Trigger. Is C++ the only plausible option? I keep getting told that C++ is the language of choice for games, but is this the case even for 2D, turn-based games? Are any other languages good for this sort of thing? I'm really big on clean, readable, extendible code, so a language that fosters that sort of thing would be great. Doing this for fun, not business. Java is the only language I really know well right now. By the way, this is my first question and I'm a noob. I read the FAQ, but if I'm doing anything noobish anyway, then I'm sorry.

• Waiting for a submitted job to finish in Oracle PL/SQL?

  - by vicjugador

  I'm looking for the equivalent of Java's thread.join() in PL/SQL. I.e. I want to kick off a number of jobs (threads), and then wait for them to finish. How is this possible in PL/SQL? I'm thinking of using dbms_job.submit (I know it's deprecated). dbms_scheduler is also an alternative. My code: DECLARE jobno1 number; jobno2 number; BEGIN dbms_job.submit(jobno1,'begin dbms_lock.sleep(10); dbms_output.put_line(''job 1 exit'');end;'); dbms_job.submit(jobno2,'begin dbms_lock.sleep(10); dbms_output.put_line(''job 2 exit'');end;'); dbms_job.run(jobno1); dbms_job.run(jobno2); //Need code to Wait for jobno1 to finish //Need code to Wait for jobno2 to finish END;

• I need guidance in building my first C# project

  - by grokker

  Hi I'm a PHP developer and I have some experience with Java. I'm trying to learn C# and my first project would be a program that starts the timer on a PC by clicking a button on another PC in the network. The problem is, I don't know where to start? What do I need to read up on? The OS for both PCs is Windows XP so they're desktop apps. I'd appreciate any help from you C# gurus. I hope my start as a C# programmer would be successful. Thank you!

• API for configuring static IP addresses in an android application

  - by awoodland

  Is it possible to set the IP address of an interface in Android within an application? I can query the available interfaces and their current addresses using java.net.NetworkInterface, but this doesn't provide a facility to change these. Did I just miss something somewhere or is it not allowed? I was hoping to be able to make my application either change or add an alias to one or more of the existing interfaces at runtime on an "off the shelf" device. (2.1/2.2). Ideally I'd like to do this for both IPv4 and v6 addresses.

• What do I need to learn to make a website that can make a text file?

  - by lala

  I want to make a website, but all I know is basic HTML and CSS. On this website, I want the user to input in multiple text fields (sort of like they take a quiz) and then the program will make a text file based on the user input which the user can download. I want it to work backwards, too, so that the text file is the input. What do I need to learn to make a website to do this? Will javascript do the trick? I'm a beginning to intermediate programmer, mainly with java and I've learned some C# recently. I thought I could learn ASP.Net for this, but it turns out my hosting doesn't support it.

• Sharing Eclipse directory on Dropbox between Windows and Mac OS X

  - by sowbug

  This question was close to mine, but not quite. I have a Windows desktop and a MacBook Pro. I'd like to be able to keep my Eclipse workspace in my Dropbox folder. The problem is that many project settings change between platforms: references to JREs, JDKs, and other libs. Every discussion I've seen of this problem seems to suggest taking advantage of the source control system's ignore functionality, so that such-and-such file remains local-only and thus able to remain platform-specific. But when you're working with a real single shared folder, that class of solution doesn't apply. Have you had luck working with a Java Eclipse project living in a single folder shared over the network, cross-platform?

• Log4J - Speed of resolving class/method/line references

  - by Jeach

  Does log4J still gather the class, method and line numbers by generating exceptions and inspecting the stack trace? Or has Java been optimized since Sun included their own logging framework. If not, why has there not been any optimizations made since. What is the main challenges in obtaining class, method and line numbers quickly and efficiently? Although I hate annotations and try to avoid them, has log4J not made use of this, such as: @log4j-class MyClass @log4j-method currentMethodOne At least this would avoid some companies bad habit of repeatedly writing/copying the method name as the first part of their logging message (which is seriously annoying). Thanks, Jeach!

• MultiThreading question

  - by TiGer

  Hi, I am developing on Android but the question might be just as valid on any other Java platform. I have developed a multi-threaded app. Lets say I have a first class that needs to do a time-intensive task, thus this work is done in another Thread. When it's done that same Thread will return the time-intensive task result to another (3rd) class. This last class will do something and return it's result to the first-starting class. I have noticed though that the first class will be waiting the whole time, maybe because this is some kind of loop ? Also I'd like the Thread-class to stop itself, as in when it has passed it's result to the third class it should simply stop. The third class has to do it's work without being "incapsulated" in the second class (the Thread one). Anyone knows how to accomplish this ? right now the experience is that the first one seems to be waiting (hanging) till the second and the third one are done :(
