Android Application Development

Alright with new technologies comming up every day, it has become very important to keep ourself updated. Today I tried my hands on developing my first Android application.

All these days I was thinking what all it takes to develop an android application on any computer but the answer was as simple as

1) Java SDK, 2) Android SDK and 3) Eclipse IDE

Not so easily do you find a good tutorials to get yourself kick started in learning new technologies, but we were lucky enough get few. This Getting Started tutorial (Video series) is really helpful to begin with and get acquainted with the basic stuffs.

I created my first “Hello Android” application today and couple of others (Flashlight etc), its fun.

This is all for now, will keep you posted. Share your thoughts 🙂

Joomla – User Authentication Using External Database (MySql)


Yesterday it was my first experience in working on a Joomla website. I was asked to develop a new site in Joomla for an existing site which had many existing registered users. So the first challenge for me was to allow those existing registered user to be able to login & use the new website with their existing credentials.

After a lot of search on Google, I found very useful plug-in MySql Auth Plugin for Joomla 1.5 which I thought I should share with you all.

MySql Auth Plugin for Joomla 1.5 let authenticate users against an external MySQL database and is fully configurable from Admin area. You can configure the host, port, database name, user data table, username column, password column, first name column, last name column and email column from the Manage Plugin section in the admin.

Below are the screen shot of MySql Auth Plugin administration panel

If you have a similar requirement, I would 100% recommend this plugin to you.

Google Maps Javascript API V3 Example

Google Maps – one of the best resource available on the web that brings the world on your computer screen. With google maps distant places are just a few clicks away from you.

Google maps javascript api is amongst the most widely used api on the web as it easily lets you embed Google Maps in your own web pages. Version 3 or V3 as its called of this API is especially designed to be faster and more applicable to mobile devices, as well as traditional desktop browser applications.

New Features

1. You can now specify the inclusion of optional libraries for specialized functionality in the Maps API!

2. Add animations to your markers! Make your markers drop or bounce when placed on the map.

3. The Google Maps API no longer requires a Maps API key!

4. The Google Static Maps service now supports custom styled maps!

Google Geocoding/Reverse Geocoding Service

Geocoding is the process of converting addresses (like “Taj mahal Agra, Tajganj, Agra, Uttar Pradesh 282001, India“) into geographic coordinates (like latitude 27.173006 and longitude 78.042086), which you can use to place markers or position the map.

The Google Geocoding API provides a direct way to access a geocoder via an HTTP request. Additionally, the service allows you to perform the converse operation (turning coordinates into addresses); this process is known as “reverse geocoding.”

I have created a sample application “Map My Address” for those those who want to start using Google Maps on the web pages.

Sample URL:

Asp.Net User Control and Telerik ToolTip

Hi friends,

Another great day has ended let me share a new thing I learnt today. I have been using a lot of Telerik Asp.Net Ajax Controls these days and I must say they really help achieving complex goals by making your work simple. Telerik Asp.Net Ajax Controls is a set of useful controls like RadGrid, RadListview, RadAjaxPanel, RadProxyManager, Rad ToolTip Manaager and many more.

In this post I will share a solution to a problem which most of the user face when using Asp.Net UserControl with Telerik ToolTip.

The Telerik Tooltip control can display rich content like text, images and even standard ASP.NET and user controls. The built-in ASP.NET AJAX mechanism allows loads content after the user hovers with the mouse over the trigger element. It allows you to easily add tooltips to a single or groups of elements, or all elements on the page at once. You can configure the way the ToolTip is displayed –side, offset, and relative to the mouse or to a triggering element. Telerik ToolTip control provides several types of animations – Fade, Resize, slide, fade in to show hide the tooltip.

But a general problem faced by Telerik Tooltip users is rebinding the usercontrol data when using tooltip control for more then one item without making a page refresh because at time it seems Telerik Tooltip cache the data but this is not the case.

To correctly configure a Telerik Tooltip you should fulfil the following basic criteria:

1) The new values in the user control’s content controls should always be set in the user control’s PreRender event.

If you are using the Telerik Tooltip inside any List control like Grid, ListView or Repeater, you should not that

1) The targets should always be added to the RadToolTipManager’s TargetControls collection in the list control’s OnItemDataBound event.

2) The TargetControls collection should be cleared when the list control is paged and sorted.

3) If you have ajaxified the list control, you should add the tooltip manager to the same settings – e.g put the tooltip manager in the same update panel or add it to the same ajax settings of ajax manager where the list control is added.

Please feel free to contact me isncase you face any problem 🙂

Twitter like Message Alerts using JQuery

Hello Reader, 

Today I am here to share a cool way of showing message alerts on you your websites.  

It is very common to show custom message alerts to users/visitors on a website on the occurence of some events like validation errors on login or sign up forms or on data add/update or delete. Most of the times we use the common javascript alert() function to show such message which shows an ugly message box to the users or try to use a ready made third party tools which does similar task but loads your webpages with JS scripts and hampers the speed of your website and somtimes the performace of your web applications too. 

But why should you show those ugly message box or load your webspage with extra JS files when you have easy solutions with jQuery

jQuery is a lightweight cross-browser JavaScript library that emphasizes interaction between JavaScript and HTML. Used by over 27% of the 10,000 most visited websites, jQuery is the most popular JavaScript library in use today.

So here goes the code you implement on your webpages to show smart message alerts to visitor of your website. 

Step 1 

Download (if you dont already have) the latest version of jQuery script from and include it on your webpage. 

Step 2 

Include this div at the top inside the body tag of your webpage 

Step 3 

Include the following CSS style in you stylesheet file. This controls the appearance and position of the Message Alert container. 

height:40px;width:99.8%;background-color:#ffffff;color:#000;font-family:”Trebuchet MS”, Tahoma; font-size:18px; text-align:center;display: none;border:1px solid #562c2c; margin:0 0 0 0;padding-top:10px;}

Step 4

Include this javascript function in you webpage

function ShowNotification(message, showwait, hidewait) {
$(“#divSlideMessage”).oneTime(showwait, function() {
}).oneTime(hidewait, “soon”, function() {

Step 5 (Final Step)

Now use ShowNotification(message, showwait, hidewait) function in place alert() or any other function that you were using to show the message alerts.

ShowNotification accepts three arguments

message – your alert message

showwait – time in milliseconds, after how long the message should be shown

hidewait – time in milliseconds, after how long should it dissappear

Hope this helps, please feel free to contact me in case you find any problem.

The Stock Market

The Pig Story

Once upon a time in a village, a man appeared and announced to the villagers that he would buy PIGS for Rs. 10.

The villagers seeing that there were many PIGS around, went out,to the forest and started catching them. The man bought thousands at Rs. 10 and as supply started to diminish, the villagers stopped their effort. He further announced that he would now buy at Rs. 20. This renewed the efforts of the villagers and they started catching PIGS again.

Soon the supply diminished even further and people started going back to their farms. The offer rate increased to Rs. 25 and the supply of PIGS became so little that it was an effort to even see a PIGS, let alone catch it!

The man now announced that he would buy PIGS at Rs. 50! However, since he had to go to the city on some business, his assistant would now buy on behalf of him.

In the absence of the man, the assistant told the villagers.Look at all these PIGS in the big cage that the man has collected. I will sell them to you at Rs.35 and when the man returns from the city, you can sell it to him for Rs.50.”

The villagers squeezed up with all their savings and bought all the PIGS. Then they never saw the man nor his assistant, only PIGS everywhere!!!

Video Gallery for WordPress WebSite

Happy New Year Readers,

It has been quite a few months since I wrote my last blog post. Last few months I have been busy working on projects using Telerik Ajax Tools and WordPress. Today I am sharing my experience about creating a Custom Video Gallery for your wordpress site.

My projects requirement was a Video Gallery that can have videos from various sites like Youtube, Google, Vimeo, Dailymotion and more as well as videos (flv, swf etc) uploaded on clients server.

Usually you can always find a readymade free plugin for everything you want on your wordpress site but this is not the case everytime. Alter a lot of search on Google, I could find a lot of video related plugins like Vipers Video Quicktags but none directly fulfilled my requirement.

Viper Video Quicktags is a very useful plugin which allows easy and XHTML valid posting of videos from various websites such as YouTube, DailyMotion, Vimeo, and more. So finally we choose to create a Custom Video Gallery using Viper Video Quicktags.

My Video Gallery looks like this

Video Gallery

On the right appears a carousel with a list of video available from which you can select a video to be played.
If you have a similar requirement or you need more information on this feel free to contact me 🙂

Gantt Chart with Google Charts

Hi Friends

Graphs & Charts are used to illustrate many types of data and are not limited to the simpler types such as line, bar, and circle. They help to make facts clearer and more understandable. Beautiful Graphs and Charts always adds to any report or analysis.

One such chart is Gantt Chart, Gantt chart is a specialized bar chart used to provide a graphical overview and schedule of tasks. It helps in analysis of planed goals and actuals results. This is a chart with rectangular bars.

In one of my project I was required to create a graphical report to compare forecasted and actual Milestone data. So I felt Gantt Chart is the best way to display the comparison. After some research on google I found an easy way of creating Gantt Chart using Google Charts API.

Here is a sample code for it

<img src=”
&chtt=My Gnatt Chart
&chdlp=b” />

My Gantt Chart

For any queries, confusion or R&D you can consult Google Chart API Documentation or you can also post your queries here.

Hope this post helps you, thanks for reading 🙂

Animated Banner With JQuery

Post Data using ASP.NET Web Browser Control

Hello People,

Its almost 2 AM here at my place, need a sound sleep from so many days but before that let me share this trick with you all.

Have you ever used ASP.NET Web Browser for your application, give it a try! its very useful. It really helped me sort out a big problem in one of my application where I previously was using HttpWebRequest but I got stuck when the page I was posting data to used a cookie checking before processing any request and the cookie was created using javascript.

As far as from my research I have found you cannot fire a javascript code on a page using HttpWebRequest, please correct me if I am wrong anywhere, anyways so this was my problem. Finally i came through Web Browser control and gave it a try. Because it works similar to any browser, client side script (javascript) aslo worked fine in it 🙂

Here is a small excerpt from my code

AxWebBrowser wb = new AxWebBrowser ();
object vPost = null;
object vHeaders = null;
object obj = null;
object url = “”;
object cPostData = null;

cPostData = “var1=data1&var2=datra2&var3=data3&var4=data4”;

vHeaders = “Content-Type: application/x-www-form-urlencoded” + Convert.ToChar(10) + Convert.ToChar(13);
(You can add other headers as required)

vPost = ASCIIEncoding.ASCII.GetBytes((string)cPostData);
wb.Navigate2(ref url, ref obj, ref obj, ref vPost, ref vHeaders);

This is all it takes to post data programmatically to a page using Web Browser control in you desktop application.

Hope this helps you, if you have any queries please feel free to ask.
