Simple Application, ListBox and Item

Simple ListBox exercise…..  create two list box , one button and one label as following picture.

Select button and set the properties text  as  “Add Item” , and ID as “addItem”
For the First list box click the upper right icon and “Edit item”

null

And then , show the ListItem Collection Editor

To add the item –> Click Add button and Input the Text properties  anything you want.


After finish Adding item Click ok.    You will get the list of all items in the first Listbox
To add the code, Double click on  “Add button”  and put the following code.

using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;

public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{

}
protected void adItem_Click(object sender, EventArgs e)
{
if (ListBox1.SelectedIndex != -1) // to check, is there any item in the first listbox is selected.
{
Label1.Text = “Move -> ” + ListBox1.SelectedItem.Value; // show, the moved item
ListBox2.Items.Add(ListBox1.SelectedItem.Text); // add the selected item to the second listbox.
ListBox1.Items.RemoveAt(ListBox1.SelectedIndex); // Remove the selected item from the first listbox
}
else
{
Label1.Text = “Error , Please item you want to move “;
}
}
}

The game of life, the classic problem and unbeliverable.

What is the game of life ????

The game of life ( or simply life ) is not a game in convenional sense. There are no players , and no winning or losing. One the “piece” are placed in the starting position, the rules determine everything that happens later.  Nevertheless , life is full of surprise! In most cases, it is impossible to look at starting position ( or pattern ) and see what will happen in the future. The only way to find out is to follow the rules of the game…..

There is a good reference site for the rule of this game go to this link : http://www.math.com/students/wonders/life/life.html or if you want to see some online example go : http://www.bitstorm.org/gameoflife/ and this is my code for the game of life in C++ version ( and very simple one )

The publication, book and tape classes , more advance….

Add another base class sales that holds and array of three floats it can record the sales of a particular publication for the last three months. Include getdata() function to get three sales amounts from the user , and a putdata() function to display the sales figures. Alter the book and tape classes so that they are derived from both publication and sales. An object of class book or tape should input or output sales along with its other data.

#include
using namespace std;

class sale
{
private:
float salerec[3];
public:
void getdata()
{
cout << " Enter the sales for the last three months :" << endl; for (int i = 0; i < 3 ; i++) { cout << " Enter sales for month : " << i+1 << " > “;
cin >> salerec[i];
}
}
void putdata()
{
cout << " The sale of the last three month " << endl; for(int i=0; i < 3; i++) { cout << " Month no : " << i+1 << " > ” << salerec[i] << endl; } } }; class publication { private: char title[50] ; float price; public: void getdata() { cout << " Enter publication title : " ; cin >> title;
cout << " Enter publication price : " ; cin >> price;
}

void putdata()
{
cout << " Publication title : " << title << endl; cout << " Publication price : " << price << endl; } }; // end of class publication class book : public publication, public sale { private: int pageCount ; public: void getdata() { publication::getdata(); cout << " Enter page count : " ; cin >> pageCount;

sale::getdata();
}
void putdata()

Inheritance , Classroom Exercise, NIIT student

Create a class called publication that store the title ( a string ) and price ( type float ) of a publication. From this class, derive two class: book which adds a page count ( type int ); and tape , which adds a playing time (type int ) in minutes. Each of these classes should have a getdata() function to get its data from the user, and a putdata() to display its data.

//———————————————————

#include
using namespace std;
class publication
{
private:
char title[50] ;
float price;
public:
void getdata()
{
cout << " Enter publication title : " ; cin >> title;
cout << " Enter publication price : " ; cin >> price;
}

void putdata()
{
cout << " Publication title : " << title << endl; cout << " Publication price : " << price << endl; } }; // end of class publication class book : public publication { private: int pageCount ; public: void getdata() { publication::getdata(); cout << " Enter page count : " ; cin >> pageCount;
}
void putdata()
{
publication::putdata();
cout << " Page count : " << pageCount ; cout << endl; } }; class tape : public publication { private: int playingtime; public: void getdata() { publication::getdata(); cout << " Enter page count : "; cin >> playingtime;
}
void putdata()
{
publication::putdata();
cout << " Playing time : " << playingtime; cout << endl; } }; int main(int argc, char** argv) { book mybook; tape mytape; // get the book data mybook.getdata(); mybook.putdata(); // get the tape data mytape.getdata(); mytape.putdata(); return (EXIT_SUCCESS); } [/sourcecode] ..

This is another version of Filled / Unfilled Dimon , using OOP.
and try to use inheritance , base class , derive class. . . . have fun

The .NET Framework …

The Microsoft .NET Framework is at the heart of the .NET startegy. This framework manages and execute applications and Web services, contains a class libaray( called the .NET Framework Class Library, or FCL ) , enforces security and provides many other programming capabilites.

The Common Language Runtime (CLR) is another central part of the .NET Framework –it executes .NET programs. Programs are compiled into machine-specific instructions in two steps. First, the program is compiled in to Microsoft Intermediate Language (MSIL) , wich defines instructions for the CLR. Code converted into MSIL from other languages and sources can be woven together by the CLR. The MSIL for an application’s components is placed into the application’s executable file ( known as an assembly ). When the application executes, another compiler ( known as the just-in-time compiler or JIT compiler )  in the CLR translates the MSIL in the executable file into machine-language code, then the machine-laguage code executes on the platform.

Note. MSIL is Microsoft’s name for what the C# language specification refers to as Common Intermediate Language (CIL)

C#

C# , developed at Microsoft by a team lead by Anders Hejlsberg and Scoot Wiltamuth, was designed specifically for the .NET platform as a langauge that would enable programmers to mirgrate easily to .NET.
It has roots in C, C++ and Java, adapting the best features of each and adding new features of its own. C# is object oriented and contains a powerful  class library of prebuilt components , enabling programmers to develop application quickly . C# is appropriate for demanding application development tasks, especially for building today’s popular Web-based applications.

The  .NET platform is one over which Web-based applications can be distributed to a greate variety of devices and to desktop computers.  The .NET platform enables language interoperability: Software components from different languages can interact as never before.
