Reference "kernel32" to read and write ini configuration files

OverView

kernel32.dll is a very important 32-bit dynamic link library file in Windows, which belongs to the kernel-level file. It controls the system's memory management, data input and output operations and interrupt processing. When Windows starts, kernel32.dll resides in a specific write-protected area in the memory, so that other programs cannot occupy this memory area.

Precautions:

• ini file path must be complete
• The ini file path must use \, because in VC++, \\ only means \
• You can put ini in the directory where the program is located, at this time the IpFileName parameter is ".\FileName.ini"

GetPrivateProfileInt

Use this method to get ini type data, if not, it will take the default data set

UINT WINAPI GetPrivateProfileInt
(
_In_LPCTSTR lpAppName, //ini文件中区块名称
_In_LPCTSTR lpKeyName, //键名
_In_INT nDefault, //默认值
_In_LPCTSTR lpFileName //ini文件路径
);

GetPrivateProfileString

Use this method to get string type data, if not, it will take the default data set

UINT WINAPI GetPrivateProfileString
(
_In_LPCTSTR lpAppName, //ini文件中区块名称
_In_LPCTSTR lpKeyName, //键名
_In_INT nDefault, //默认值
_In_LPSTR lpReturnedString,//接受ini文件中值的CString对象，指定一个字符串缓冲区，长度至少为nSize
_In_DWORD nSize,//指定装载到IpReturnedString缓冲区的最大字符数
_In_LPCTSTR lpFileName //ini文件路径
);

Write

Writes values ​​to ini, so just writing strings is enough

WritePrivateProfileString

BOOL WritePrivateProfileString(
LPCTSTR lpAppName,//ini文件中区块名
LPCTSTR lpKeyName,//键名
LPCTSTR lpString,//键值
LPCTSTR lpFileName
);
