Is there any particular way to integrate Captch code validation in iPhone application?
is this possible to create captcha? (with or without web-service / any API)
If any kind of external library or any source is required to be imported, then also please let me know.
Any kind of link or source code is available then please suggest me.
Also suggest from where to start to do this, if possible.
Thanks in advance.
I know you probably don't want to hear this, but why do you need captcha on iPhone? It's completely useless since there are no bots or something.
But if you really need it then make some image with white background and then use this code

to add text to the image... once you'll have this, then just check if the entered string is equal to the randomly generated one on the image and you are good to go.
I didn't find any libraries which could be used as a captcha, so I think this is probably the best solution right now.

The question I am asking is a little bit abstract, so I will try to make it more clear. There are websites where you sign up and get a signature in the format of an image. It has a general format, say a few boxes that are empty, and a logo in the middle. Now, say you gain the "Overachiever" badge, which looks like a pen. You signature is then updated, automatically, to include that pen badge in one of the blank boxes. I am completely clueless as to how to do this, and in what language to do this is, so can anyone help? I have been thinking about PHP as an option, but I do not know if that would work. Any suggestions?
You can do this with PHP (imagecreate) and for the updates in your images you can use cronjobs.
Is this for a forum? Depending on the platform, I know some hosts already have "addon's" that provide similar functionality to what you're after. (Karma addons etc.)
Maybe one of these will help? phpBB has some stuff like that.

If you can execute an external process, you can do this using Image Magick.
I have been looking for the name of this UI element for a while now, but I cant come up with anything. What is the name of the round rect with 'Reloading Data' in it? I thought that I remembered using a view like this a while back, and there was some open source library that made its use much easier.

The Apple API is private and cannot be used in AppStore apps. I and many others use MBProgressHUD: http://cocoadev.com/wiki/MBProgressHUD.
It's MBProgressHUD.
You will get more opensource controls on this link.
Why don't you just use a UIActivityIndicator? It essentially provides the same utility without the need to implement 3rd party code? Do you really need any custom behavior the class does not already provide? The simpler the better you know..? ;)
So, I'm starting to use GWT and I am having a little problem.
I have to retrieve some information about a building and I want to show to the user a floorplan for him to choose from where does he want information to be shown.
So, I tried an imagemap, but Iit is not working. Do someone has any suggestion or example of that?
Thank you,
Mauricio
I'm sure there are a couple ways of going about this. You might want to try some extension of the an already existing class as was done here with ComplexPanel http://www.koders.com/java/fid1ACE81656C6F49C2E81126751E938A61215D6A6F.aspx?s=mdef%3ainsert
i want to read text in an image how to do that...
Thanks
What you’re asking about is called OCR, and it isn’t as simple as you might think. Luckily, there is at least one open-source effort to do it.
You need an OCR library, see this question for further information. For a more specific answer, you might want to post a more specific question.
I'm writing an app, where I the user has to be able to select multiple adresses. I wanted to solve this in the same way, apple does when you send an SMS to someone.
You can enter text and it gets surrounded by a blue bubble for each adress selected.
I've already found facebook's tree20-kit, but I can't get it to work because of some linker error I cannot solve.
Is there any other kit out there, that's capable of doing this, or do you have any suggestions on how to create such a textField?
Yours,

Interesting. I don't know of any other open source solutions for this, and I think writing from scratch would be much more time consuming than trying to resolve the linker error. I would recommend spending a few hours and do the following:
Create a new empty application.
Download Three20 and follow the detailed instructions on GitHub for linking the framework.
You should be able to get this to link as many others, including myself, have been able to use this framework.
Sorry this isn't a straight forward answer to your question. I hope it was helpful just the same. Andrew.
