读取注册表REG_DWORD类型的键值：
DWORD dwRet = 0;
HKEY hKey;
if(RegOpenKeyEx(HKEY_LOCAL_MACHINE,"SYSTEM//Select",0,KEY_QUERY_VALUE,&hKey)==ERROR_SUCCESS)
{
DWORD dwValue,dwType;
DWORD dwBufLen=255;
if(RegQueryValueEx(hKey,"dw",NULL,&dwType,(LPBYTE)&dwValue,&dwBufLen)==ERROR_SUCCESS)
{
if(dwType==REG_DWORD)
dwRet = dwValue;
}
RegCloseKey(hKey);
}
return dwRet;
}
读取REG_BINARY键值:
if(dwType == REG_BINARY)
dwRet = dwValue;
你自要用itoa()将读出来的数据转成String,
参数添加按什么radix转的应该就可以了！！！
