使用文本注册表—INI文件

1：“注册表”类是CRegister，DOS版本不支持多线程中的同步，但WINDOWS版本支持多线程中的同步 ；本接口能够将在键值后面的注释，在修改后仍能正确的写回。

2：主要接口如下所示

FILE* GetFile(){return(m_pFile);}; //判断文件是否装载成功

static int Atoi(char *pStr);//计算16进制值

static int GetCount(char *pStr,char nCh);//计算”串”中的”某一字符”的出现频率

static char* GetString(int nIndex,char nCh,char *pStrSource);//从串中得到以某字符分隔的串

static char* TrimLeft(char *pStr);//将”串”中的左空格删去

static char* TrimRight(char *pStr); //将”串”中的右空格删去

static BOOL IsProfileBoolen(char *pStr); //判断”串”是否表达真

//读键值

char* GetProfileString(char *pStrSegment,char *pStrKey,char *pStrDefault="");

long GetProfileLong(char *pStrSegment,char *pStrKey,long lDefault=0L);

WORD GetProfileWord(char *pStrSegment,char *pStrKey,WORD wDefault);

int GetProfileInt(char *pStrSegment,char *pStrKey, int nDefault);

float GetProfileFloat(char *pStrSegment,char *pStrKey,float fDefault);

double GetProfileDouble(char *pStrSegment,char *pStrKey,double dbDefault);

//写键值

BOOL WriteProfileString(char *pStrSegment,char *pStrKey,char *pStrDefault);

BOOL WriteProfileLong(char *pStrSegment,char *pStrKey,long lDefault);

BOOL WriteProfileWord(char *pStrSegment,char *pStrKey,WORD wDefault);

BOOL WriteProfileInt(char *pStrSegment,char *pStrKey, int nDefault);

BOOL WriteProfileFloat(char *pStrSegment,char *pStrKey,float fDefault);

BOOL WriteProfileDouble(char *pStrSegment,char *pStrKey,double dbDefault);

3：使用举例

#include “Symbol.h”

#include “Register.h”

BOOL MySample_27()

{

CRegister* pRegister = new CRegister("Config.SYS");

if (pRegister == NULL || NULL == pRegister->GetFile())

{

DELETE(pRegister);

return(FALSE);

}

//读一整数

int nHello = pRegister->GetProfileInt(” Boot”, “Hello”, 37);

//读一无符号整数

int nSign = pRegister->GetProfileInt(” Boot”, “Sign”, 37u);

//读一长整数

long lgGood = pRegister->GetProfileLong(” Boot”, “Good”, 37L);

//读单精度浮点数

float fData = pRegister->GetProfileFloat(” Boot”, ”LiPing”, 0.5f);

//读双精度浮点数

double dbData = pRegister->GetProfileDouble(” Boot”, ”Line4”, 3.7);

//读布尔变量

BOOL bBoolV = pRegister->IsProfileBoolen(pRegister->GetProfileString(“Boot”,”BootV”,”True”));

//读字符串

char strPrintName[256];

_fstrcpy(strPrintName, pRegister->GetProfileString(” Boot”, “Print”, “LPT1”));

//写一整数

pRegister->WriteProfileInt(” Boot”, “Hello”, nHello);

//写一无符号整数

pRegister->WriteProfileInt(” Boot”, “Sign”, nSign);

//写一长整数

pRegister->WriteProfileLong(” Boot”, “Good”, lgGood);

//写单精度浮点数

pRegister->WriteProfileFloat(” Boot”, ”LiPing”, fData);

//写双精度浮点数

pRegister->WriteProfileDouble(” Boot”, ”Line4”, dbData);

//写布尔变量

pRegister->WriteProfileString(“Boot”,”BootV”,((bBoolV)?”True”:”False”));

//写字符串

pRegister->WriteProfileString(” Boot”, “Print”, strPrintName);

delete pRegister;
