i am new in symbain. i have no idea how to create symbian dll and using it in a symbian application.
i am looking some sort of tutorial or guide for:
1. how to create a dll in symbian c++?
2. how to use the created dll in an symbian app?
thanks in advance.
Start at hemelix, especially here and here, then take a look at the official documentation at Nokia Symbian Belle Developers' Library which also contains examples (for example here and here).
(Let me warn you though: Symbian development is really tough. Think twice before diving in...)

I'm a .NET developer with some questions about a small Mac project coming up.
We are going to be creating a small program for Mac OSX. The software will need to have a simple UI (1 screen) and will need to consume a WCF web service.
Should we code on our Windows boxes or on Mac machines? We have a couple Mac Minis, but we mostly do Windows development.
What IDE/dev environment should we use? (Eclipse, Xcode, etc.)
How does Mac software deployment generally work?
...
No one has mentioned Java/Eclipse. Isn't that an option?
Here are two options:
Write in Objective-C, using Xcode on Macs
Write in C#, using Mono on Windows or on a Mac with SharpDevelop
The advantage of #1 is the resulting app will be much easier to deploy to others, but you might have trouble consuming the WCF service. It depends on what exact interface you are exposing and what the types of the parameters are.
The advantage of #2 is that you can use your C# skills. I don't know the state of WCF in Mono, and the GUI may not look native.
If you go with #1, the main issue will be using Objective-C. Since you are targeting the Mac, make sure you enable the Garbage Collector, or else you will have to also learn memory-management. If you use Xcode 4, it's similar in spirit to Visual Studio, although the details are different. For a simple project, following the tutorials will probably be enough -- I suspect the hard part will be interacting with WCF. To make your life easier, make the interface to the service extremely simple (simple parameter types and returns).
Your question is overly broad. You have two options:
When in Rome...: download Xcode, look at example apps, read Apple's documentation, find some tutorials, and learn Mac app development the usual way.
The Devil You Know...: look into stuff like the Mono project that will let you write a Mac app in C#, so you can use your existing libraries and don't have to learn Objective-C.
Which is better depends on your needs. If you just want to get a small app done and don't have a lot of time/money, I'd go with #2. If you're concerned about quality (compatibility libraries always have their quirks), I'd go with #1. My gut says #2 is better for you.
I just started to learning the Adobe AIR. I think I would learn quite fast by referring the sample applications. Can you let me know any Adobe AIR open source applications?
Thanks for your help.
Over 20 example apps (from Adobe):
http://www.adobe.com/devnet/air/samples_actionscript.html
The following sample applications will help you get started using Adobe AIR. These are basic applications built by Adobe engineers to demonstrate the capabilities of the runtime.
There are 75 air samples here http://code.google.com/p/jsairsamples/
You can thousands of code samples, implementation in the Tour De Flex app. This app is like a documentation and also a component library which shows small code implementation of what the components displayed can do.
You can get it here.
I would like to write an app for the iPad but I can't stand Objective-C.
Is there a language generator that would spit out Objective-C but let me write my iPad application in another language?
I've heard a little about MacRuby and am curious whether it could be used this way. Any other similar projects in other languages?
C# with MonoTouch.
JavaScript with Appcelerator Titanium.
Flex with ELIPS Studio 3.
Python with PyObjC (for jailbroken iPhones though).
Apparently Lua is an option.
John McIntosh uses Smalltalk on the iPhone. For instance, his Mobile Wiki Server app.
No computer anywhere (well maybe some) cares what language you write your programs in. Heck, you could hand-write machine instructions if you were patient (and crazy) enough. As long as you can figure out how to interact properly with the system call interface and the ABI, you can do whatever you want.
You could use Corona, Torque, or Unity. These all have advantages and disadvantages compared to using the standard Objective-C SDK, but really, if it's about the language itself, it's hard to see how you would be better able to "stand" the languages supported by these three than Objective-C.
I've been programming in VB.net for a while now, and I finally got access to a mac to make ipod apps. What are some useful sites, videos, etc. that could help me get used to Objective C and the Xcode IDE? I've stumbled upon the samples on the apple dev site, but none of them really give good examples which I could learn the syntax of the language from.
Thanks for the help, Objective C is really a big change from VB.net!
Here are some helpful starter references from the Apple site, first for Objective-C itself, then for the Cocoa frameworks.
Learning Objective-C: A Primer
Cocoa Fundamentals Guide
There are also "getting started" videos available from http://developer.apple.com/iphone (you have to register as a developer to get access, but that's free)
You might want to take a look at MonoTouch if you like working with .Net. As far as I'm aware, it only works with C#, but it will let you use the .NET api to program for the iPhone. Might be worth looking into if you don't want to learn Objective C.
I have a Symbian 9.1 handset, Nokia E65, based on Nokia S60 series UI. I'd like to build a simple, full screen, graphic application. It should be able to display some text and pictures and have a basic interaction from the keyboard. That's for me only, not to be deployed.
Now, what do you think is the quickest and most painless way to have it done?
I have the following skills:
- HTML, PHP, ASP.net, JS
- ASP.net and C#, Silverlight
- Java, but mostly for networking, not UI
- Some C++
I have downloaded the Nokia IDE, but it is scary at first sight :)
Any tutorial or example are welcome!
Edit:
In particular, two questions:
is there a possibility to make a stand-alone flash application for that handset?
how about the QT mobile version?
For your device, definitely use Python for S60. It is much easier to start with than Symbian's C++ SDK and in case you ever need more low level functionality than python gives you, you can write small modules in c++ and use them in your Python program.
For a simple application like the one you are describing, Python will do just fine. You don't even need any of Nokia's IDEs / tools on the PC, you can just write the code in any text editor, copy it to the phone and test it live.
As others have mentioned, other options include:
Symbian C++ SDK : As you have discovered the tools and not the most intuitive to work with, development is not straight forward either.
Nokia's WRT : Using javascript/css/html, but it is not available for your phone.
Qt : Not available for your phone.
Java Me : Probably your second best option, your code will be slightly larger but more protable. The tools are not as straight forward as with Python, but definitely not as complicated as with Symbian.
If you think you may like to do some further development on the Symbian platform in future, I'd strongly suggest looking at Qt. Unfortunately, however, you can't use it on your E65, since Qt requires S60 3.1 or higher. (The E65 runs S60 3.0).
Since Qt coding in done in C++, you also have access to native platform APIs if required. For most apps however, the (considerably more user-friendly) Qt APIs provide all the functionality you need.
Depending on your background, the learning curve may be steeper than using Java or Python, but the pay-off is that you get access to a very powerful toolkit. And of course, as long as you use only Qt APIs, your app should be easily portable to other Qt platforms if necessary.
Go for Java ME.
All the things you list in your post is possible to do in Java.
The Symbian SDK for C++ can be downloaded here.
NSBasic is another option.

Dan
May I suggest Python? For newer Symbian handsets I'd recommend Web Runtime (WRT), but it is not supported on good old E65.
I'm obviously biased but I would suggest getting the 2D graphics example code from the "Quick Recipes On Symbian OS" book:
If you know HTML and JS already, you should be able to write a Web widget for your Symbian device pretty easily, using the tools available through Forum Nokia. More info here:
http://www.forum.nokia.com/Technology_Topics/Web_Technologies/Web_Runtime/
These widgets are standalone full screen applications that use the device WebKit browser engine for rendering and UI. You can also use keyboard inputs and customize the softkeys if you wish.
