iPhone SDK

An SDK for iPhone development is released on 6^th March 2008. Using this SDK, developer can develop application is iPhone and iTouch devices. It came up with an iPhone simulator  to test application. SDK requires Apple Developer Licence to launch application on any iPhone device.  Like Mac operating system, iPhone OS also based on Xcode.  The main components of this SDK are:

1. Cocoa Touch
2. Media
3. Core Services
4. OS X kernal

MonoTouch

MonoTouch allows developers to create C# and .NET based applications that run on Apple’s iPhone and Apple’s iPod Touch devices, while taking advantage of the iPhone APIs and reusing both code and libraries that have been built for .NET, as well as existing skills. (MonoTouch, 2009).

PhoneGap

PhoneGap basically generates native wrappers for what are still web apps. What PhoneGap provides beyond that is a bridge between JavaScript and native device APIs. So, you write JavaScript against PhoneGap APIs, and PhoneGap then makes the appropriate corresponding native call. In that respect, it is different from deploying a plain old web app. (Stackoverflow, 2009).

Corona

Corono is web based application development for iPhone-based devices. It supports html, javascipt, action script (flash) and a good platform for highly graphic basic applications , games etc. This is very latest platform in iPhone development world and the team releases daily updates on this SDK. Research on increasing graphic speed and flash based application integration in iPhone is progress with the Corona team. This platform is not free. A limited feature trail version is available for free. For full SDK, you need to spend 99 dollars.

Appcelerator

Appcelerator Titanium is an open source platform for developing mobile and desktop applications using web technologies. Appcelerator Titanium is frequently compared to Adobe Air for developing desktop applications for Windows, Mac and Linux. The tool can deploy standalone applications for Mac, Windows, and Linux from any of those platforms. It does this by submitting the source files to a proprietary server-side solution which then returns the binaries. However, to develop an iPhone application using this tool you need a Mac Os and iPhone SDK.

Of course, it is not my post. But I wrote it here for a back up for myself. I got this from some website, it works !

Steps1)

1. Stop running Mysql service  first (Administrative tools > Services )
2. Open command prompt (cmd) and reach the directory  (using CD command) where Mysql bin  is installed (eg: C:/Program Files/Mysql/bin)
3. type mysqld.exe -u root –skip-grant-tables and press enter (don’t close this command prompt)
4. Open new command prompt and reach the same  Mysql bin directory
5. type mysql and press enter (This time, it never prompts for any passwords and you can enter mysql console)
6. type command use mysql to switch your database into mysql
7. Execute the usual command to change password for rootUPDATE user SET Password = PASSWORD(’your_new_password’) WHERE User = ‘root’;
8. Close the command prompts and go to services , start mysql. Now you can login with your new root password

Thanks and have a nice day

Recently I created a sliding menu for a project using jQuery and ScrollTo functions.

See demo: Slider  Menu

We can use the jQuery function $(”.menubar”).scrollTo(id_of_element) to scroll any scrollable area to a particular location.

The idea behind every smooth sliding is using scroll function with overflow:hidden mode.

You can download the source code from : http://www.sajithmr.me/downloads/slider/slider.zip

Here div menu-bar is the scrollable div with overflow:hidden mode contains set of menu and a duplicate as a  buffer

At the bottom of the code, you can see a filler div, this is for filling the menu one by one to the right side menu-bar to make the sliding very smooth

The function setMotion(this) calls  the scroll function and it moves till the called DOM object’s id reaches

If you use an ajax call after the motion to load the content at the bottom, you can make this sliding menu for proper navigation purpose.

Thanks

Happy new year
Mr.

This is a lazy post. Read the following first:

Lorem ipsum dolor sit amet, consectetur adipiscing elit. Sed mattis placerat dolor at accumsan. Aenean quis magna eget dolor adipiscing porttitor. Sed vestibulum placerat neque, in lacinia mauris luctus in. Aliquam adipiscing commodo hendrerit. Proin a metus id diam malesuada egestas. Mauris nisi sem, ullamcorper nec elementum sit amet, adipiscing vitae erat. Aliquam gravida faucibus justo ac tincidunt. Aliquam erat volutpat. In eros ante, accumsan venenatis molestie eu, malesuada sed massa.

You may familiarised with these words from several demo websites. This is the by default content of most of the wordpress demo themes and demo designs and all. These text have no meaning, that is the main meaning of these text. The visitor needs to concentrate on the design, not the text content, that is the purpose of these meaningless text.

http://www.lipsum.com/

This website helps in creating more such dummy content for any area of text. Instead of typing “content here” or dummy “adsfasdfasdfa” texts, this content can be used as a dummy filler.

When we use mixed html and flash content, we usually face the problem of overlapping flash contents over html text. In the case of mere html we use z-index to format which content should be on top. But Z-index cannot do nothing here. So the recommended option is wmode parameter.   Sometimes the wmode mode also does not help us to avoid this overlapping problem. This is because sometimes we forgot to add wmode in two places. We need to add wmode = transparent  or opaque in both flash var and in embedded tag parameter like this:

<param name=”wmode” value=”transparent”>

<object wmode=”transparent” />

A detailed description can be found from the makers : http://kb2.adobe.com/cps/142/tn_14201.html

Here, a new plugin of jQuery can be used to display the flash messages like twitter. (see twitter’s settings page)

I added some more functions to this plugin to display the notification in different context, say information, warning or error message. The function show_flash(’message here’); can be used for this purpose. Second parameter is the type of message. For example, show_flash(’Error in deleting file’, ‘error’) OR  show_flash(’Email address entered is invalid’, ‘warning’)

If you use sessions to save flash message , for example in codeigniter $this->session->set_flashdata(’message’,'hello’); you can use this plugin to display them by adding a php code in the footer  (or header) of every page

<?php if($this->session->flashdata(’message’) != ” )  : ?>

<script>show_flash(’<?= $this->session->flashdata(’message’) ?>’)</script>

<?php endif; ?>

Use the below code to change the dimensions of an iframe in runtime.

<script type=”text/javascript”>

parent.$(”#fancy_outer”).width(100); parent.$(”#fancy_outer”).height(120);

</script>
