Sub Api_PathFileExistsample()

Class Module クラスモジュール

今回はclsファイルから抜き出したので上にVersion Begin　Attribute　などの記述がありますが、クラスモジュールの名前を明記するためで、削除してかまいません。
またこのままテキストエディタでファイルを新規作成してコピーし保存後、
API_PathFileExistClass.clsに変えるとクラスモジュールに変わります。

API_PathFileExistClass.cls

VERSION 1.0 CLASS
BEGIN
  MultiUse = -1  'True
END
Attribute VB_Name = "API_PathFileExistClass"
Attribute VB_GlobalNameSpace = False
Attribute VB_Creatable = False
Attribute VB_PredeclaredId = False
Attribute VB_Exposed = False
Option Explicit
# If VBA7 Then
'パスまたはファイルが存在するか
Private Declare PtrSafe Function PathFileExists Lib "SHLWAPI.DLL" Alias "PathFileExistsA" (ByVal pszPath As String) As Long
# Else
Private Declare Function PathFileExists Lib "SHLWAPI.DLL" Alias "PathFileExistsA" (ByVal pszPath As String) As Long
# End If

Public Function Win32APiPathFileExistsA(strFileName) As Boolean
Win32APiPathFileExistsA = CBool(Abs(PathFileExists(strFileName)) * (-1))
End Function

長所

FSOと異なりファイルやフォルダの区別をしない

1個のクラスモジュール、1個の関数でファイル、フォルダに対応

Win64とWin32の共用化が容易

というか普通がおかしいと思う

Declare FunctionからTrue Falseを取るテクニック

Win32はTrueは1でVBAはマイナス1です。
このため、絶対値にマイナス1を掛けてCboolで真偽に変えます。

Property Getを使った例との対比

FilesizeはFilesystemobjectです

CreateFileを使うとうまくいかないので断念しました。今後の課題です。
しかしこれはファイル、フォルダいずれにも対応しています。

標準モジュール

Sub Api_PathFileExistsample()
With New API_PathFileExistClass
Debug.Print .getPathFileExistsAValue("C:\Users\username\OneDrive\ドキュメント\2010\2010.pdf")
Debug.Print .getPathFileExistsAValue("C:\Users\username\OneDrive\ドキュメント\2010\")
Debug.Print .getPathFileExistsAValue("C:\Users\username\OneDrive\ドキュメント\2010")
End With
End Sub

クラスモジュール

API_PathFileExistClass.cls


VERSION 1.0 CLASS
BEGIN
  MultiUse = -1  'True
END
Attribute VB_Name = "API_PathFileExistClass"
Attribute VB_GlobalNameSpace = False
Attribute VB_Creatable = False
Attribute VB_PredeclaredId = False
Attribute VB_Exposed = False
Option Explicit
# If VBA7 Then
'パスまたはファイルが存在するか
Private Declare PtrSafe Function PathFileExists Lib "SHLWAPI.DLL" Alias "PathFileExistsA" (ByVal pszPath As String) As Long
# Else
Private Declare Function PathFileExists Lib "SHLWAPI.DLL" Alias "PathFileExistsA" (ByVal pszPath As String) As Long
# End If

Private Function Win32APiPathFileExistsA(strfilename) As Boolean
Win32APiPathFileExistsA = CBool(Abs(PathFileExists(strfilename)) * (-1))
End Function

' accessor
Property Get getPathFileExistsAValue(strfilename) As Boolean
getPathFileExistsAValue = Win32APiPathFileExistsA(strfilename)
End Property

このようにシンプルなので比較が容易

フォルダ名の末尾はバックスラッシュ(円マーク)がついてもつかなくても判定する

末尾を気にする必要がない

FSOよりたぶん早い

クラスモジュールはWith クラス名でインスタンスなしで使える

今回学んだ重要な点はこれで、実は変数の宣言、New命令によるインスタンスの作成なしで使える。このため標準モジュールにはDimがいらない。きわめてシンプルになります。

クラスモジュール化すると、標準モジュールがシンプルなのでコードの可読性が高まる

Declareが上にないので、わかりやすいコードになります。

強化版Class

強化版Classモジュール用のサンプル

GetDiskFreeSpaceExによる2gbを超えるドライブの容量

GetFileAttributeAによるPathFileAttribute、フォルダ、ファイルの属性。特にファイルかフォルダかの判定に使用

Api_SetCuurentDirectory

指定したフォルダをカレントにする

GetWindowsDirectory,GetSytemDirectory,GetTempPath

それぞれWindows,System,Tempのフォルダ名

PathIsDirectory

有効なディレクトリか

PathAddBackslash

Directoryの最後に\を追加する。ついていたら追加しない。
これを作っておくと、フォルダ名の末尾に悩まないし & "" & を書かなくてよい。

strCurrentDirectory

カレントのディレクトリを返す

strFileTitle

フルパスからファイル名（Basename + 拡張子)を取得

ShortPath

ShortPathを作成する。FSOと違って一瞬

Filesize

現在これはFilesystemobjectです。

20190605更新

APIでファイルサイズが取得できるようになりました

https://tsware.jp/labo/labo_25.htm
こちらのサイトを参考にProperty Get lgFIleSizeAPI(strPath As String) As Long
を作りました

注意

ただしフォルダは0で返ります

FSOを強化

コードを作り直し、ファイルもフォルダも値を返し、エラーは-1が返るようにしました
