MkDir 语句

在数据媒体中创建新目录。

语法：

MkDir Text As String

参数：

Text：用于指定要创建目录的名称和路径的任意字符串表达式。您也可以使用 URL 表示法。

如果不能确定路径，则在当前目录下创建指定的目录。

错误代码：

5 无效的过程调用

76 未找到路径

示例：

Sub ExampleFileIO

' 有关文件组织的函数示例

Const sFile1 As String = "file://c|/autoexec.bat"

Const sDir1 As String = "file://c|/Temp"

Const sSubDir1 As String ="测试"

Const sFile2 As String = "Copied.tmp"

Const sFile3 As String = "Renamed.tmp"

Dim sFile As String

    sFile = sDir1 + "/" + sSubDir1

    ChDir( sDir1 )

    If Dir(sSubDir1,16)="" Then ' 目录是否存在？

        MkDir sSubDir1

        MsgBox sFile,0,"创建目录"

    End If

    sFile = sFile + "/" + sFile2

    FileCopy sFile1 , sFile

    MsgBox fSysURL(CurDir()),0,"当前目录"

    MsgBox sFile & Chr(13) & FileDateTime( sFile ),0,"Creation time"

    MsgBox sFile & Chr(13)& FileLen( sFile ),0,"文件长度"

    MsgBox sFile & Chr(13)& GetAttr( sFile ),0,"文件属性"

    Name sFile As sDir1 + "/" + sSubDir1 + "/" + sFile3

    ' 在同一个目录中重命名

    sFile = sDir1 + "/" + sSubDir1 + "/" + sFile3

    SetAttr( sFile, 0 ) ' 删除所有属性

    MsgBox sFile & Chr(13) & GetAttr( sFile ),0,"新文件属性"

    Kill sFile

    RmDir sDir1 + "/" + sSubDir1

End Sub

 

' 将系统路径转换为 URL

Function fSysURL( fSysFp As String ) As String

Dim iPos As String

    iPos = 1

    iPos = Instr(iPos,fSysFp, getPathSeparator())

    Do While iPos > 0

        Mid( fSysFp, iPos , 1,"/")

        iPos = Instr(iPos+1,fSysFp, getPathSeparator())

    Loop

    ' DOS 中的冒号

    iPos = Instr(1,fSysFp,":")

    If iPos > 0 Then Mid( fSysFp, iPos , 1,"|")

    fSysURL = "file://" & fSysFp

End Function
