About:

The Big Data Tech Conclave Winter Edition will be an ideal forum to discuss the way forward in addressing the key issues, and we look forward to see you on board an actively share, benchmark and discuss the emerging technologies, tools and challenges and identify the immense opportunities available in Big Data for you and your organization.

The winter edition will feature presentations, workshops, case studies and key insights into Algorithms and Machine Learning, Analytic Insights, Architectural Patterns, Data Management, Design/Interface and Visualization, Enterprise IT, Testing, Privacy, Compliance and Governance.

Key emphasis will be provided in areas such as parallel computing innovations in Big Data, Harnessing and inferencing the Semantic Web, SQL on Haddoop and blending the traditional RDBMS and NOSQL databases with a special focus on workshops around some key tools / technologies in this space such as Impala, Parallel Computing with R, Stinger, Spark/Shark, Gehi, Drill, Apache Mahout and SparQL.

We would like to take this opportunity to thank all our Speakers, Sponsors and Delegates who made the spring edition of the Big Data Tech conclave 2013, which was held on 26 & 27 April 2013 at The Marriott Whitefield Bangalore, a thumping success.

Big Data Tech Conclave 2013 saw over 300 delegates participate from enterprise, Technology, ITES, Big Data Start ups, venture capitals and Data centers, reiterating that India is the place to be, if you want to take Big Data to the next level.

We thank all our esteemed participants for the valuable feedback and suggestions that we have received in helping us design the winter edition of the Big Data Tech Conclave 2013 to be held on the 6th to the 7th of December 2013.

During the spring edition, few companies were keen to use the platform to post jobs for talent acquisition in Big Data. For the winter edition we would be creating a job posting link on the bigdataconclave.com website.

Displaying Messages in Alert using LWUIT

Displaying Messages in Alert using LWUIT for Nokia

Displaying Alert in LWUIT for Nokia

When using LWUIT we should first add and initialise LWUIT in our project.If you want to know how to add LWUIT and Initialise LWUIT please read our previous post NOKIA MOBILE APPLICATION DEVELOPMENT STAGE 3 first then only you can use the following tutorial.

Alert in LWUIT is somewhat different from Alert in LCUDI.We have Alert class in LCUDI which can be directly used in our project instead of that we have to Dialog Class in LWUIT

To create an Alert in LWUIT:

Dialog alert=new Dialog();

alert.setTitle("Alert Message");

You can also set timeout for each alert message in LWUIT like in LCUDI but the time must in Microsecond format.

To set timeOut for Alert in LWUIT:

alert.setTimeout(2000);

To display the alert in screen you can use two different ways one is using show() method another one is to use showDialog() method.

show() method:

show(int,int,int,int,boolean) is the syntax for show method in which you have to mention the position of the Alert message and final argument boolean is used to mention whether to include the Title for Alert or not (True for showing Title and False for not showing)

e.g

alert.Show(90,90,10,10,true);

showDialog() method:

ShowDialog() doesn't accept any parameters but when you use the showDialog() method your alert message will be in centre of screen by default.

e.g

alert.showDialog();

SAMPLE CODE:

import javax.microedition.midlet.MIDlet;
import javax.microedition.midlet.MIDletStateChangeException;

import com.sun.lwuit.Button;
import com.sun.lwuit.Dialog;
import com.sun.lwuit.Display;
import com.sun.lwuit.Form;
import com.sun.lwuit.events.ActionEvent;
import com.sun.lwuit.events.ActionListener;

public class TestClass extends MIDlet {

Form f1;
Button b1;
Dialog alert;

public TestClass() {
// TODO Auto-generated constructor stub
}

protected void destroyApp(boolean arg0) throws MIDletStateChangeException {
// TODO Auto-generated method stub

}

protected void pauseApp() {
// TODO Auto-generated method stub

}

protected void startApp() throws MIDletStateChangeException {
// TODO Auto-generated method stub
Display.init(this);
f1=new Form("LWUIT Alert");
b1=new Button("Show Alert");
b1.addActionListener(new ActionListener()
{
public void actionPerformed(ActionEvent ae)
{
alert=new Dialog();
alert.setTitle("I am a Alert");
alert.setTimeout(2000);
alert.showDialog();
}
});
f1.addComponent(b1);
f1.show();

}

}

The output will resemble the one given below

Windows phone application development for beginner

Windows Phone for Absoulte Beginners part 4

Working with CheckBox:

The specialty of check box is that we can choose multiple choices from the given also we can able to select nothing from the list. Check boxes are normally have two states such as checked and unchecked if checked means its Boolean equivalent is true, if unchecked means its Boolean equivalent is false.

Using Check box in Windows phone:

To use Check box in Windows Phone use the following code given below.

To access the state of Checkbox in c# code use as following

checkBox1.IsChecked

This will return the state of checkbox whether it is checked or not in bool? type

To make Checkbox to be enable by default use the following code

So the code is actually IsChecked=”True”.

Here we developed a simple application where we have four checkboxes and we show the number of checkboxes in checkboxes checked in run time in a textbox below.

Sample Application:

MainPage.xaml

<phone:PhoneApplicationPage

x:Class="TextBox.MainPage"

xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

xmlns:phone="clr-namespace:Microsoft.Phone.Controls;assembly=Microsoft.Phone"

xmlns:shell="clr-namespace:Microsoft.Phone.Shell;assembly=Microsoft.Phone"

xmlns:d="http://schemas.microsoft.com/expression/blend/2008"

xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"

mc:Ignorable="d" d:DesignWidth="480" d:DesignHeight="768"

FontFamily="{StaticResource PhoneFontFamilyNormal}"

FontSize="{StaticResource PhoneFontSizeNormal}"

Foreground="{StaticResource PhoneForegroundBrush}"

SupportedOrientations="PortraitOrLandscape" Orientation="Portrait"

shell:SystemTray.IsVisible="True">

<Grid.RowDefinitions>

</Grid.RowDefinitions>

</Grid>

</phone:PhoneApplicationPage>

Here we generated two methods checked and unchecked where checked will work whenever the checkbox is checked and whenever checkbox is unchecked uncheck method will work. We provided screen shots of how to generate the Check and Unchecked methods here

{

count++;
