写入配置的函数WritePrivateProfileString和读取配置文件的函数GetPrivateProfileInt和GetPrivateProfileString

头文件

Windows.h

举个例子，配置文件set.cfg内容：

[testdata]
UserName=600511005
Password=112233
ResetSeqNumFlag=Y
InputType=Z
ClOrdID =9893

[section]
key=string

[Student]
Name=jacky

函数GetPrivateProfileInt可以读取配置文件中的数字，

UINT WINAPI GetPrivateProfileInt(
_In_ LPCTSTR lpAppName,
_In_ LPCTSTR lpKeyName,
_In_ INT     nDefault,
_In_ LPCTSTR lpFileName
);

如

UINT dwClOrdID = GetPrivateProfileInt("testdata","ClOrdID",0, "./set.cfg");

读取字符串稍微复杂，如

同样，可以利用函数WritePrivateProfileString将配置写到文件中，

写配置所用的代码如下：

WritePrivateProfileString (TEXT("Section1"),
TEXT("FirstKey"),
TEXT("It all worked out OK."),
TEXT("appname.ini"));
WritePrivateProfileString (TEXT("Section1"),
TEXT("SecondKey"),
TEXT("By golly, it works!"),
TEXT("appname.ini"));
WritePrivateProfileString (TEXT("Section1"),
TEXT("ThirdKey"),
TEXT("Another test..."),
TEXT("appname.ini"));

// Test
GetPrivateProfileString (TEXT("Section1"),
TEXT("FirstKey"),
TEXT("Error: GPPS failed"),
inBuf,
80,
TEXT("appname.ini"));
_tprintf (TEXT("Key: %s\n"), inBuf);
