# 一.Win32数据类型 #

Win32的api对c/c++的基本数据类型重新进行了命名,本来是好事,但实在是太多了.不过多熟悉就知道了

MSDN参考:[http://msdn.microsoft.com/en-us/library/aa383751(v=vs.85).aspx][http_msdn.microsoft.com_en-us_library_aa383751_v_vs.85_.aspx]

编码参考

#include "stdafx.h" #include <string> #include <iostream> #include <windows.h> int _tmain(int argc, _TCHAR* argv[])
    {
    using namespace std;
    
    //BOOL BOOL result;
    PBOOL pbool=&result;
    result=TRUE;
    result=FALSE;
    if(result)
        result=0;
    else result=1;
    
    if(result)
        result=0;
    else result=1;
    //END BOOL //BYTE BYTE byteDemo=255;
    PBYTE pbyte=&byteDemo;
    //same as BYTE BOOLEAN boolDemo=1;
    PBOOLEAN pboolean=&boolDemo;
    UCHAR ucharDemo=255;
    
    //CHAR CHAR charDemo='a';
    CHAR charArr[]="hello";
    //Point To CHAR LPSTR pchar=&charDemo;
    
    //WCHAR WCHAR wcharDemo1='O';
    WCHAR wcharDemo2[]=L"我a";
    //Point To WCHAR LPWSTR pwchar=&wcharDemo1;
    
    LPTSTR generalChar=&wcharDemo1;
    
    LPVOID pvoid=&wcharDemo1;
    
    //CONST CONST int number1=1;
    //INT INT number3=100;
    LPINT pint=&number3;
    UINT number4=100;
    
    PUINT puint=&number4;
    //error LPUINT pint=&number3; //DWORD unsigned long DWORD number2=200;
    LPDWORD pdword=&number2;
    //WORD WORD number7=200;
    LPWORD pword=&number7;
    //LONG LONG number5=100;
    PLONG plong=&number5;
    //SHORT SHORT number6=100;
    
      return 0;
    }

# 二.字符串 #

参考:

char为8为ANSI，wchar\_t为16位Unicode

char char1='a';
    char chararr[]="hello";
    
    wchar_t wchar1=L'好';
    wchar_t wchar[]=L"你好";

**加L表示为Unicode编码**,Win32定义为CHAR和WCHAR.

使用TEXT宏能使用CHAR和WCHAR(系统自动判别)

TCHAR c=TEXT('A');
    TCHAR cc[]=TEXT("Asss");

TEXT宏与\_T类型,如\_T("Asss");

# 三.数据类型转换总结 #

参考:

[http://www.shenmiguo.com/archives/2009/275\_cplus-type-cast.html][http_www.shenmiguo.com_archives_2009_275_cplus-type-cast.html]

代码说明了应用了

# 四.Rectangle Functions #

部分Win32API,实现对RECT进行操作

Test

RECT rcClient1={};
    RECT rcClient2={};
    OffsetRect(&rcClient1,22,0);
    IsRectEmpty(&rcClient1);
    EqualRect(&rcClient1,&rcClient2);

# 五.\_\_uuidof #

是c++的一个关键字,取GUID用的.

参考：[http://www.cppblog.com/woaidongmao/archive/2008/11/09/66391.html][http_www.cppblog.com_woaidongmao_archive_2008_11_09_66391.html]

这样就可以直接认类和接口,而不用去找GUID的常量了

# 六.结构体初始化,按顺序 #

这个属于基础的,只是我不知道而已

struct point {
       int x;   
       int y;
    } spot = { 20, 40 };    
    
    point p1={0,0};
    point p2={0};

用花括号按顺序初始化值,如果初值表未满则为初始值.

point p3=\{\};不同于point p3;,point p3=\{\};会进行数据初始化
