使用boost库删除文件夹时出现问题 [英] Problem in deleting a folder using boost library

问题描述

先生，我正在使用boost库进行各种文件处理。我在使用boost库删除文件夹时遇到问题。

我用过它，

  #include   <   boost \filesystem \operations。 hpp  >  //作为头文件
  
 boost :: filesystem :: path fOne =   c：\\A;  //  在主代码中 
 
 boost :: filesystem :: remove_all（fOne）; 

这适用于多个地点（例如在C：\\ A）



但是当我试试这个时位置C：\\Windows \\A可执行文件成功构建，零错误和零警告。然后，当我尝试执行按钮上执行的功能时，单击一个消息框打开，如此



未处理的异常在0x75CBD8A8在HelpProject.exe：微软C ++异常：升压::文件系统:: filesystem_error内存位置0x0018EF68



我发现这是一个错误如何解决这类错误？



我在调试代码方面有一些知识，但不知道生成的可执行文件。所以我关闭了visual studio并打开了可执行文件，并尝试执行函数

并且它显示我这样，



调试错误中止（）已经调用了！



我尝试在管理员模式下打开可执行文件但没有用



Am我错过了什么？

我应该添加更多信息吗？



谢谢

解决方案

请阅读 remove_all（）的文档[ ^ ]：

Quote：

抛出：如错误报告中所述。

按照那里的链接错误报告 [ ^ ]：

Quote：

当执行程序调用操作系统或其他底层操作时API导致错误导致函数无法满足其规范，抛出类型filesystem_error的例外。

因此您必须捕获并处理异常。阅读一些关于C ++异常的教程和 Boost Filesystem exception.hpp Header [ ^ ]。

Sir, I am using boost libraries for various file handling purposes. I have a problem in deleting a folder using boost libraries.
I used this,

#include<boost\filesystem\operations.hpp>// as a header file

boost::filesystem::path fOne = "c:\\A";// in main code

boost::filesystem::remove_all(fOne);

This works for the several locations(for e.g in C:\\A)

But when I try this location C:\\Windows\\A the executable builds successfully with zero error and zero warning.Then when I tried to execute the function which executes on button click a message box opens like this

Unhandled exception at 0x75CBD8A8 in HelpProject.exe: Microsoft C++ exception: boost::filesystem::filesystem_error at memory location 0x0018EF68.

I found this was an error message how can I solve this type of errors?

I have some knowledge in debugging the code but not the generated executable. So I closed the visual studio and opened the executable and tried to execute the function
and it shows me like this,

Debug error abort() has called!

I tried by opening the executable in administrator mode but no use

Am I missing anything?
Should I add still more information?

Thank you

解决方案

Just read the documentation for remove_all()[^]:

Quote:

Throws: As specified in Error reporting.

Follow the link there to Error-reporting[^]:

Quote:

When a call by the implementation to an operating system or other underlying API results in an error that prevents the function from meeting its specifications, an exception of type filesystem_error is thrown.

So you have to catch and handle the exception. Read some tutorial about C++ exceptions and Boost Filesystem exception.hpp Header[^].
