视窗7隐藏档案上的流 does
原标题:ofstream doesn t work on Windows 7 hidden file

我认识到ofstream 视窗7的隐蔽档案上没有工作。

这里是快速试验守则。

#include <fstream>
#include <iostream>
#include <tchar.h>
#include <windows.h>

int main() {    
    {
        std::ifstream file2(_T("c:\a.txt"));
        if (file2.is_open()) {
            std::cout << "ifstream open" << std::endl;
        } else {
            std::cout << "ifstream not open!" << std::endl;
        }
    }

    // SetFileAttributes(_T("c:\a.txt"), FILE_ATTRIBUTE_NORMAL);
    SetFileAttributes(_T("c:\a.txt"), FILE_ATTRIBUTE_HIDDEN);

    {
        std::ofstream file(_T("c:\a.txt"));
        if (file.is_open()) {
            std::cout << "ofstream open" << std::endl;
        } else {
            std::cout << "ofstream not open!" << std::endl;
        }
    }
    getchar();
}

这里是我正在取得的产出。

ifstream open
ofstream not open!

如果我使用<代码>FILE_ATTRIBUTE_NORMAL,ofstream将成功开放。

我没有担任署长。 但我确实使用以下联系人方案。

“linker

如果我们不开始作为署长提出申请,就必须把No>改为 可调用用户账户控制(UAC)。 本组织将帮助我们把实际文件写到<编码>C:UsersyccheokAppData LocalVirtualStorea.txt。 而不是保护的<代码>C:

最佳回答

是的。 FILE_ATTRIBUTE_HIDDEN or FILE_ATTRIBUTE_SYSTEM

或更可读:/CreateFile 如果对-CREATE_ALWAYS-FILE_ATTRIBUTE_NORMAL作了具体规定,如果档案有,则该代码即告失效。 FILE_ATTRIBUTE_HIDDEN and/or FILE_ATTRIBUTE_SYSTEM Depende.

具体做法是:ofstream callsCreateFile
