Windows数据类型
一、基础类型(Windows中源代码:)typedef unsigned long DWORD;typedef int BOOL; //TRUE、FALSEtypedef unsigned char BYTE;typedef unsigned short WORD;typedef float
一、基础类型
(Windows中源代码:)
typedef unsigned long DWORD; typedef int BOOL; //TRUE、FALSE typedef unsigned char BYTE; typedef unsigned short WORD; typedef float FLOAT; typedef FLOAT *PFLOAT; typedef BOOL near * PBOOL; typedef BOOL far * LPBOOL; typedef BYTE near*PBYTE; typedef BYTE far *LPBYTE; typedef int near*PINT; typedef int far*LPINT; typedef WORD near* PWORD; typedef WORD far *LPWORD; typedef long far *LPLONG; typedef DWORD near*PDWORD; typedef DWORD far*LPDWORD; typedef void far *LPVOID; typedef CONST void far *LPCVOID; typedef int INT; typedef unsigned int UINT; typedef unsigned int *PUINT;
转化后:
typedef unsigned long DWORD; typedef int BOOL;//TRUE FALSE typedef unsigned char BYTE; typedef unsigned short WORD; typedef float FLOAT; typedef FLOAT* PFLOAT; typedef BOOL* PBOOL; typedef BOOL* LPBOOL; typedef BYTE* PBYTE; typedef BYTE* LPBYTE; typedef int* PINT; typedef int* LPINT; typedef WORD* PWORD; typedef WORD* LPWORD; typedef long* LPLONG; typedef DWORD* PDWORD; typedef DWORD* LPDWORD; typedef void* LPVOID; typedef CONST void* LPCVOID; typedef int INT; typedef unsigned int UINT; typedef unsigned int* PUINT; #define VOID void typedef char CHAR; typedef short SHORT; typedef long LONG; typedef CHAR* PCHAR, LPSTR; //可写的指针变量 typedef CONST CHAR *LPCSTR, *PCSTR;//只读的指针变量
2、结构体类型:POINT,SIZE,RECT
typedef struct tagPOINT { LONG x; LONG y; } POINT, *PPOINT, *LPPOINT; typedef struct tagSIZE { LONG cx; LONG cy; } SIZE, *PSIZE, *LPSIZE; typedef struct tagRECT { LONG left; LONG top; LONG right; LONG bottom; } RECT, *PRECT, NEAR *NPRECT, FAR *LPRECT; typedef const RECT FAR* LPCRECT;
3、句柄类型:可以操作某一类事物的指针变量(依托),故意隐含了具体内容的一个结构体指针变量;
HWND:操作窗口的句柄
HICON:图标的句柄
HCURSOR:光标的句柄
HMENU:菜单的句柄
HDC:绘图句柄
#define DECLARE_HANDLE(name) struct name##__{int unused;}; typedef struct name##__ *name
//拆分后
#define DECLARE_HANDLE(HWND)
structHWND__{int unused;};
typedef structHWND__ *name
4、UNICODE与多字符集:是两种文字编码方式
a)多字符集:各国文字的编码之间有些重叠的编码(编码冲突)
const char* p = "abc221@%#$%";
p = "中国";
b)UNICODE:各国编码统一编码
const wchar_t* p = L"abcd32$";
c)wchar_t是属于双字节变量;
d)UNICODE的字符串常量必须在前面加一个大写L;
e)TCHAR类型是两种编码格式的自适应类型;
#include <iostream> int WINAPI WinMain(HINSTANCE hInstance,HINSTANCE hPrevInstance,LPSTR lpCmdLine,int nCmdShow) { const char *p="中文";//多字符集编码 //p="abc3"; //Unicode编码 const wchar_t *pU=L"中文";//Unicode编码 return 0; }
开放原子开发者工作坊旨在鼓励更多人参与开源活动,与志同道合的开发者们相互交流开发经验、分享开发心得、获取前沿技术趋势。工作坊有多种形式的开发者活动,如meetup、训练营等,主打技术交流,干货满满,真诚地邀请各位开发者共同参与!
