C++.NET Windows Forms Course

L01 - Introduction

.NET \ What will you learn?

• OOP with .NET, Thinking OOP and The Concept of .NET• Peek on C++.NET console• Debugging in .NET• Windows Forms Controls (Tabs, ComboBox, Timers, ...etc)• Drawing with .NET• Collections

.NET \ What will you learn?

• Event Handling • Exception Handling • Files processing - Strings Manipulating• Dynamic Controls associated with Event Handling• The Concept of C#

What’s .NET?

• .NET Framework :– A collection of technologies that …

• Unite isolated applications• Make information available anytime, anywhere• Simplify development and deployment

What’s .NET?

• .NET Framework :– Common Language Runtime* – provides an abstraction layer over the

operating system– Base Class Libraries

• pre-built code for common low-level programming tasks

– Development frameworks and technologies • Reusable• customizable solutions for larger programming tasks

_________________________________________________

*The Common Language Runtime (CLR) is the virtual machine component of the .NET Framework. All .NET programs execute under the supervision of the CLR, guaranteeing certain properties and behaviors in the areas of memory management, security, and exception handling.

Introduction to .NET

Introduction to .NET

• The .NET Framework allows you to:– Apply common skills across a variety of devices , application types ,

and programming tasks– Integrate with other tools and technologies to build the right

solution with less work– Build compelling applications faster

• .NET Framework releases :– 1 , 1.1 , 2 , 3 , 3.5 , 4, 4.5

.NET IDE and Frameworks

• .NET With Visual Studio 2008 \ 2010 \ 2012 \ 2013• Framework 3.5 \ 4.0 \ 4.5

Console

Console// CppdotNetConsoleCourseTest.cpp : main project file.

#include "stdafx.h"

using namespace System;

int main(array<System::String ^> ^args)

{

Console::WriteLine(L"Hello World");

return 0;

}

Console


#include "stdafx.h"



{


Console::ReadKey();

return 0;

}

Console

What’s this?// CppdotNetConsoleCourseTest.cpp : main project file.

#include "stdafx.h"



{


Console::ReadKey();

return 0;

}

Console

What a “namespace” is?!// CppdotNetConsoleCourseTest.cpp : main project file.

#include "stdafx.h"



{


Console::ReadKey();

return 0;

}

Console

Why using another namespace?!// CppdotNetConsoleCourseTest.cpp : main project file.

#include "stdafx.h"



{


Console::ReadKey();

return 0;

}

Console

“main”Why?

// CppdotNetConsoleCourseTest.cpp : main project file.

#include "stdafx.h"



{


Console::ReadKey();

return 0;

}

Console

Why isn’t it just a void?!Why passing a string “args”


#include "stdafx.h"



{


Console::ReadKey();

return 0;

}

Console

Easy, right?!// CppdotNetConsoleCourseTest.cpp : main project file.

#include "stdafx.h"



{


Console::ReadKey();

return 0;

}

Console

What’s that?!// CppdotNetConsoleCourseTest.cpp : main project file.

#include "stdafx.h"



{


Console::ReadKey();

return 0;

}

Console

Object/Class// CppdotNetConsoleCourseTest.cpp : main project file.

#include "stdafx.h"



{


Console::ReadKey();

return 0;

}

Console

“::” ?!// CppdotNetConsoleCourseTest.cpp : main project file.

#include "stdafx.h"



{


Console::ReadKey();

return 0;

}

Console

Console::WriteLine// CppdotNetConsoleCourseTest.cpp : main project file.

#include "stdafx.h"



{


Console::ReadKey();

return 0;

}

Console


#include "stdafx.h"



{

Console ^myConsole=gcew Console();


Console::ReadKey();

return 0;

}

Console

Creating an instance of class “Console”// CppdotNetConsoleCourseTest.cpp : main project file.

#include "stdafx.h"



{

Console ^myConsole=gcew Console();


Console::ReadKey();

return 0;

}


#include "stdafx.h"



{


Console::Write("Hi, again!");

Console::WriteLine("\n Hi, again!");


Console::ReadKey();

return 0;

}


#include "stdafx.h"



{



Console::WriteLine("\n Hi, again!");


Console::ReadKey();

return 0;

}

Hello World

Hi, again!

Hi, again!

Hi, again!


#include "stdafx.h"



{

String ^str1=gcnew String("Hi Hi Hi, first time.");

String ^str2="Hi Hi Hi, second time.";

String ^str3;

Console::Write("Enter your name plz: ");

str3=Console::ReadLine();

Console::WriteLine(str1 + " " + str2 + " Hi " + str3 + "!");

Console::ReadKey();

return 0;

}

Console

Everything is dynamically allocated through pointer!// CppdotNetConsoleCourseTest.cpp : main project file.

#include "stdafx.h"



{



String ^str3;




Console::ReadKey();

return 0;

}

Console

Why no gcnew here?!// CppdotNetConsoleCourseTest.cpp : main project file.

#include "stdafx.h"



{



String ^str3;




Console::ReadKey();

return 0;

}


#include "stdafx.h"



{



String ^str3;




Console::ReadKey();

return 0;

}

Console

Returns the string that’s read from the input buffer// CppdotNetConsoleCourseTest.cpp : main project file.

#include "stdafx.h"



{



String ^str3;




Console::ReadKey();

return 0;

}

Console


#include "stdafx.h"



{

int i=1;

float f=0;

Console::WriteLine(i.ToString() + f.ToString());

Console::ReadKey();

return 0;

}

Console

It’s not a “->”


#include "stdafx.h"



{

int i=1;

float f=0;


Console::ReadKey();

return 0;

}

Console

Where this method “ToString()” comes from?!


#include "stdafx.h"



{

int i=1;

float f=0;


Console::ReadKey();

return 0;

}

Console


#include "stdafx.h"



{

int i=1;

float f=0;


Console::ReadKey();

return 0;

}

10


#include "stdafx.h"



{

int i=1;

float f=0;

Console::WriteLine(i + f);

Console::ReadKey();

return 0;

}

Console

No “ToString()” method!// CppdotNetConsoleCourseTest.cpp : main project file.

#include "stdafx.h"



{

int i=1;

float f=0;


Console::ReadKey();

return 0;

}

Console

How compiler works?!// CppdotNetConsoleCourseTest.cpp : main project file.

#include "stdafx.h"



{

int i=1;

float f=0;


Console::ReadKey();

return 0;

}

Console

Arithmetic “Sum”!// CppdotNetConsoleCourseTest.cpp : main project file.

#include "stdafx.h"



{

int i=1;

float f=0;


Console::ReadKey();

return 0;

}

Console

Results a “float”// CppdotNetConsoleCourseTest.cpp : main project file.

#include "stdafx.h"



{

int i=1;

float f=0;


Console::ReadKey();

return 0;

}

Console

Results a “float”in a “String” context


#include "stdafx.h"



{

int i=1;

float f=0;


Console::ReadKey();

return 0;

}


#include "stdafx.h"



{

int i=1;

float f=0;


Console::ReadKey();

return 0;

}

Console (Types Conversion)// CppdotNetConsoleCourseTest.cpp : main project file.

{

int i=1;

String ^str=i.ToString();

Console::WriteLine(str);

Console::ReadKey();

Arrays

Arrays

• Defining an array of string with dimension of 3

public : array <String^ , 3 > ^MyArr;

Arrays

• Defining an array of string with dimension of 3

• Everything okay?

Both are Compiler Errors!

public : array <String^ , 3 > ^MyArr;

public : array <String^ , 3 > MyArr;

public : array <String , 3 > ^MyArr;

Arrays

• Sth wrong?

array <String ^ , 1 > ^MyArr;

MyArr[0][0]="1";

Compiler error

array <String ^ , 1 > ^MyArr;

MyArr[0]=1;

Compiler error

array <String ^ , 2> ^MyArr;

MyArr=gcnew array <String^ , 2 > (100,50);

MyArr[0,0]="1";

Everything is good

Arrays

• Sth wrong?array <String ^ , 2> ^MyArr;

MyArr=gcnew array <String^ > (100,50);

MyArr[0,0]="1";

Compiler error


MyArr=gcnew array <String^ , 2 > (100,50);

MyArr[0][0]="1";

Compiler error


MyArr=gcnew array <String^ , 2 > (100)(50);

MyArr[0,0]="1";

Compiler error

Arrays

• Sth wrong?

array <String ^> ^MyArr;

MyArr=gcnew array <String^ > (50);

MyArr[0]="1";

Everything is good

Arrays

Arrays


#include "stdafx.h"


int main(array<System::String ^> ^args){

array <String ^ , 1 > ^MyArr; MyArr[0]="1";

Console::ReadKey();return 0;

}

Arrays


#include "stdafx.h"


int main(array<System::String ^> ^args){

array <String ^ , 1 > ^MyArr; MyArr[0]="1";

Console::ReadKey();return 0;

}

Ntn wrong!

Arrays

• Considering that we have a class named “CELL”array <CELL^ , 2> ^MyArr;

MyArr=gcnew array <CELL^ , 2 > (100,50);

CELL ^MyCell=gcnew CELL;

MyArr[0,0]=MyCell;
