GetPrivateProfileInt 简单的很的函数 在线等 马上给分

[zyb_debug]

无语
int main()
{
int m = GetPrivateProfileInt("test","mm",-1,"a.ini");
cout << m ;
return 0;
}
这个我的main函数

这个是ini文件 但是输出老是-1；
why 在线等

[zyb_debug]

这个是ini文件里面的 我用txt写好后后缀名转换为ini
[test]
mm = 100

[jay的Fans]

[test]
mm = 10

代码正常。
这是a.ini文件中数值。

[太乙]

UINT WINAPI GetPrivateProfileInt(
__in LPCTSTR lpAppName,
__in LPCTSTR lpKeyName,
__in INT nDefault,
__in LPCTSTR lpFileName
);
Parameters
lpAppName [in]
The name of the section in the initialization file.

lpKeyName [in]
The name of the key whose value is to be retrieved. This value is in the form of a string; the GetPrivateProfileInt function converts the string into an integer and returns the integer.

nDefault [in]
The default value to return if the key name cannot be found in the initialization file.

lpFileName [in]
The name of the initialization file. If this parameter does not contain a full path to the file, the system searches for the file in the Windows directory.

Return Value
The return value is the integer equivalent of the string following the specified key name in the specified initialization file. If the key is not found, the return value is the specified default value.

[section]
key=value

为什么我的老是返回-1哦

[wangdeqie]

---a.ini---
[test]
mm=4000

//这么写
#include <iostream.h>
#include <windows.h>
int main() 
{ 
	int m = GetPrivateProfileInt("test","mm",4069, ".\\a.ini"); 
	cout << m ; 
	return 0; 
} 

[太乙]

看来应该是没找到文件吧~~lz确定文件的命名以及路径正确？

arameters
lpAppName
[in] Pointer to a null-terminated string specifying the name of the section in the initialization file.
lpKeyName
[in] Pointer to the null-terminated string specifying the name of the key whose value is to be retrieved. This value is in the form of a string; the GetPrivateProfileInt function converts the string into an integer and returns the integer.
nDefault
[in] Default value to return if the key name cannot be found in the initialization file.
lpFileName
[in] Pointer to a null-terminated string that specifies the name of the initialization file. If this parameter does not contain a full path to the file, the system searches for the file in the Windows directory.


=======================

int m = GetPrivateProfileInt("test","mm",-1,"a.ini")；

第三个参数是你设定的如果在配置文件中找不到所要找的key的时候的返回值。。

你的文件中应该是找不到把，所以返回-1.。

[太乙]

key前面不能有空格哦~

[wangdeqie]

//也可以这么写
---a.ini---
//a.ini里的内容:
[test]   
mm=4000 
//---main.cpp---
#include <iostream.h>
#include <windows.h>
int main() 
{ 
	int m = GetPrivateProfileInt("test","mm",-1, ".\\a.ini"); 
	cout << m ; 
	return 0; 
}

把a.ini放在工程的目录下，不要放在debug、release等目录下

[jay的Fans]

那应该是LZ的那个文件的路径错误了。

[zyb_debug]

果然如此 6楼 .\\是什么意思

[hai040]

可能不能有空格

[可微函树]

GetPrivateProfileInt()返回的是五符号整型 你为什么用int存储返回值?
