1 basic types of Windows Programming foundation 1.1WIN32 Applications

1) Console Program

Windows Forms that do not need to be intact can be displayed using a DOS form

2) Win32 Form program

A program that includes a form that can interact with a program through a form

3) Win32 Library Program

Provide existing code for use by other programs

Dynamic libraries (DLLs): Can be loaded at run time.

Static library (LIB): is the program that is used to compile the link. Become part of the current program.

1.2 Header files and libraries 1.2.1 Header files

The main header file, windows.h, includes definitions commonly used by Windows, among others, and some other header files. Example:

1. Windef.h: Define the data type

2. Winbase.h: Defines the correlation function of kernel

3, WinGDI.h: Defines the drawing and the document

4, Winuser.h: Form and space

5. WinNT.h: Provides Unicode support

1.2.2 Library

1, Kernel32.lib: Provide process thread memory and so on API function definition

2. User32.lib: API functions for forms and interfaces

3, Gdi32.lib: Provide drawing, text and other API function support

1.1.1 Instance HelloWorld development environment VS2010. Errors may be reported during compilation, which may be a coding problem: Some configuration settings are required: Project-Properties---Configuration Properties-General: CharSet set to not set

/*file:helloworld.cpp *auth:sjin *date:20140519 *mail: [Email protected] */#include <iostream> #include <wi Ndows.h>int WINAPI WinMain (                     hinstance hinstance,       //handle to current instance                     hinstance hPrevInstance,      //Handle to previous instance                     LPSTR lpCmdLine,           //command line                     int nCmdShow                    //show state                     ) {MessageBox (NULL, "Hello World:", "first Win32 Test ", MB_OK); return 0;}

1.1 Writing the first form program

Process related processes such as the following:

1. Form entry function WinMain

2. Form processing function

3. Registration Form Type

4. Create a form

5. Display Form

6. Message Processing

7. Program exit

Look at the following code:

/*file:helloworld.cpp *auth:sjin *date:20140519 *mail: [Email protected] */#include <iostream> #include <wi Ndows.h>using namespace Std; hinstance G_hinst = NULL;//2 form processing function/* Function function: This function is an application-defined function.
It processes the message sent to the form * when the form processes a message message, the system calls the function * Parameters: *hwnd: A handle to the form.
*UMSG: Specifies the message type.
*wparam: Specifies the remaining, message-specific information. The content of this parameter is related to the Umsg reference value. *iparam: Specifies the remaining, message-specific information. The content of this parameter is related to the Umsg reference value.
