Windows application Framework and examples

Application framework:
The structure of the same type of application is roughly the same and has many of the same source code,
So you can use an application framework AFX (application frameworks)
Write generic source code for the same type of application.

Main wizard:
Datebase Project: Creating a Database project

MFC ActiveX Control Wizard: Creating MFC-based ActiveX controls

MFC Appwizard[dll]: Creating an MFC-based dynamic link library

MFC Appwizard[exe]: Creating MFC-based applications (most commonly used)

New database Wizard: Create a SQL Server database on SQL Servers

WIN32 application: Create a WIN32 application that can be programmed with SDK methods without using MFC

WIN32 Console Application: Create a WIN32 console application under DOS,
Programming with C + + or C language

Win32 Dynamic-link Library: Creating Win32 dynamic Link libraries, using the SDK approach

Win32 Static Library: Create a Win32 static link library, using the SDK approach

The purpose of introducing the application Wizard: to avoid programmers repeating code.

Different from DOS programs, even if a simple Windows program:
It must also show a program run window that requires writing complex program code.
The same type of application's frame window style is the same, such as the same menu bar, toolbar,
status bar and user area.
The functions of the Basic menu commands are the same, such as the same file manipulation and editing commands.

To write an MFC application that implements specific functionality:

★ According to the application features in the MFC Appwizard[exe] Application Wizard Each step of the dialog box to choose,
Create a framework for an application.

★ Use the Resource Editor to edit or add resources to the program, such as Edit menu, add dialog box, etc.

★ Use the ClassWizard Class Wizard or manually add declarations for classes, member variables, and member functions.

★ Write the specific function code as needed.

★ Compile and link programs. If the program has syntax errors, you need to modify the source program. Until there is no compile, link error,
To get an executable program.

★ Test the application functions, if the program does not implement the functions required by the programming, start the Debug debugger
Debug, find and modify the logic errors in the program design.

We can make an image summary of Visual C + + MFC Programming:

The ◇MFC application framework makes our program design work like filling questions.

The integration tools in ◇developer Studio make our program design work like a choice question,
Programmers are like skilled workers in software-integrated assembly shops.

Common file types in Visual C + +
Suffix type description
DSW Workspace files combine the details of a project into a workspace
DSP project file stores the details of the project and replaces the MAK file
Hc++ the definition code for the header file storage class
Cppc++ implementation code for member functions of the source file storage class
RC Resource script file stores resources such as menus, toolbars, and dialog boxes
RC2 resource files are used to include resources in the project
ICO icon File Store application icon
BMP bitmap File storage bitmap
CLW Class Wizard files store class information used by the ClassWizard Class Wizard

Resource identifier prefixes in MFC
Identifier prefix description
IDR_ main Menu, toolbar, application diagram
Key and accelerator tables
Idd_ dialog box
IDC_ Controls and cursors
Ids_ string
Idp_ the string for the Hint message dialog box
Id_ menu command Items
Application Examples:
Example 1: Create an application framework.
The purpose of this example is to illustrate the methods and procedures for creating a Windows application
