函数示例
示例 1
#include <MsgBoxConstants.au3>
#include <StringConstants.au3>
Example()
Func Example()
; Create a constant variable in Local scope to store the file attributes of the current script.
Local Const $sAttribute = FileGetAttrib(@ScriptFullPath)
; Display the string returned by FileGetAttrib.
MsgBox($MB_SYSTEMMODAL, "", "The attribute string: " & @CRLF & $sAttribute)
; Display the string returned by AttributeToString
MsgBox($MB_SYSTEMMODAL, "", "The attribute string with easier to understand values: " & @CRLF & _
AttributeToString($sAttribute))
EndFunc ;==>Example
Func AttributeToString($sAttribute)
; Create a 1d array of the file attribute letters by splitting the string at the comma (,).
Local $aInput = StringSplit("R,A,S,H,N,D,O,C,T", ",")
; Create a 1d array using the friendlier file attribute names by splitting the string at the comma (,).
Local $aOutput = StringSplit("Read-only /, Archive /, System /, Hidden /" & _
", Normal /, Directory /, Offline /, Compressed /, Temporary /", ",")
; Loop through the attribute letters array to replace with the friendlier value e.g. A becomes Archive or S becomes System.
For $i = 1 To $aInput[0]
$sAttribute = StringReplace($sAttribute, $aInput[$i], $aOutput[$i], 0, $STR_CASESENSE)
Next
; Remove the single space and trailing forward slash.
$sAttribute = StringTrimRight($sAttribute, 2)
; Return the attribute string.
Return $sAttribute
EndFunc ;==>AttributeToString
示例 2
#include <MsgBoxConstants.au3>
Example()
Func Example()
; Assign a variable with the filepath to check on whether it's a file or not.
Local $sFilePath = @ScriptFullPath
If IsFile($sFilePath) Then
MsgBox($MB_SYSTEMMODAL, "", "The filepath is a file.")
Else
MsgBox($MB_SYSTEMMODAL, "", "The filepath is not a file.")
EndIf
EndFunc ;==>Example
; Check if the filepath is a file. Does not validate if the file exists.
Func IsFile($sFilePath)
Return StringInStr(FileGetAttrib($sFilePath), "D") = 0
EndFunc ;==>IsFile
示例 3
#include <MsgBoxConstants.au3>
Example()
Func Example()
; Assign a variable with the filepath to check on whether it's a directory/folder or not.
Local $sFilePath = @ScriptDir
If IsDir($sFilePath) Then
MsgBox($MB_SYSTEMMODAL, "", "The filepath is a directory/folder.")
Else
MsgBox($MB_SYSTEMMODAL, "", "The filepath is not a directory/folder.")
EndIf
EndFunc ;==>Example
; Check if the filepath is a directory/folder. Does not validate if the directory/folder exists.
Func IsDir($sFilePath)
Return StringInStr(FileGetAttrib($sFilePath), "D") > 0
EndFunc ;==>IsDir
----------------------------------------
该函数可以通过命令 exect 调用
参见:
FileSetAttrib, FileGetTime, FileExists, FileGetSize, FileSetTime
exect=$var_s=FileGetAttrib('C:\pagefile.sys')||_ViewValues('$var_s') ;; 返回一个与pagefile.sys文件的属性相匹配的字符串
exect=$var_i=(StringInStr(FileGetAttrib('%P%N'),'D')~~And~~FileExists('%P%N'))?1:0||_ViewValues($var_i) ;; 检查:返回1,如果在光标文件夹下,0 - 如果文件
