写入文本文件 [英] write into text file

问题描述

我有一个写入文本文件的函数，该函数运行没有任何错误，但是当我检查文本时我发现没有任何反应，文件是空的。



当我想写分区C时出现问题，我尝试D它的工作，但为什么？

                MsgBox("Text written to file")


            Else

                MsgBox("File Does Not Exist")

    End Sub

推荐答案

这是因为分区C有一些安全性。



未经许可，您无法读取，写入文件。

That is because partition "C" has some Security.

You can't read, write to a file without permission.

您是否可以尝试写入C：驱动器的根目录？

在现代MS OS上，访问系统驱动器的根是受限制的。



我们可以知道调用方法时 _FilePath 的值是什么？

Could it be possible you are trying to write at the root of your C: drive ?
On modern MS OS's, access to the system drive's root is restricted.

May we know the value of your _FilePath at the time you are calling your method ?
