のVBA7 64 32 共用版にする

参考

ユーザー定義型を渡す
- 通常、データ構造を必要とする引数は、"long ポインタ" として宣言されます。
- long ポインタは、32 ビットの数値で、メモリ内のデータ構造をポイントします。
- long ポインタで一般的に使用されているプリフィックスは "lp" です。
- また、引数のデータ型はデータ構造の名前になります。

入手可能な Windows SDK について

重要な注意

このVBAは必ずどうでもいいフォルダやファイルを作って実験しましょう
また、ほかのDeclareの入っているVBAマクロとは一緒にしないでください。
なぜかというとPublicで宣言している部分があるためです。
これをPrivateに変えれば一応大丈夫ですが、それでもエラーが出ます。
エラーが出るだけならまだしもExcelがダウンします。
とくに設定に失敗しました、エラーが出た場合にはExcelがファイルを握って解放しなくなるため、いったんExcelを終了させることを推奨します。

サマータイムがたぶん対応できない

このVBAではタイムゾーン判定がありません。
もし日本政府が安倍晋三と経団連などの超国家資本主義に乗っ取られ、サマータイムが決定された場合にはこのシステムは再度チェックしなおさないと無理です。

コード

ポイント

Declare Dimの書き換え

いくつかのものはVBA7にするときにさらに、Win64に書き換える必要がある。
特にFileHandleがLongPtrになるため、そこで、変数（DIM）、構造体（Type）の書き換えが生じる。

CreateFileAの謎

Win32API_PtrSafe.TXT -- Declare statements for Visual Basic for Applications and Microsoft Office 2010
では

Declare PtrSafe Function CreateFile Lib "kernel32" Alias "CreateFileA" (ByVal lpFileName As String, ByVal dwDesiredAccess As Long, ByVal dwShareMode As Long, lpSecurityAttributes As SECURITY_ATTRIBUTES, ByVal dwCreationDisposition As Long, ByVal dwFlagsAndAttributes As Long, ByVal hTemplateFile As LongPtr) As LongPtr

lpSecurityAttributes As SECURITY_ATTRIBUTES
となっています。

教えて！Gooのサイトでは、

'// Win32API ファイルを作成またはオープン
Private Declare Function CreateFile Lib "kernel32.dll" _
　　Alias "CreateFileA" ( _
　　ByVal lpFileName As String, _
　　ByVal dwdesiredAccess As Long, _
　　ByVal dwShareMode As Long, _
　　ByRef lpSecurityAttributes As SECURITY_ATTRIBUTES, _
　　ByVal dwCreationDisposition As Long, _
　　ByVal dwFlagsAndAttributes As Long, _
　　ByVal hTemplateFile As Long) As Long

この行をみてください
　　ByRef lpSecurityAttributes As SECURITY_ATTRIBUTES, _
こうしている場合、Subプロシージャでは

CreateFileAはSecurite_Attribute初期化

    '// SECURITY_ATTRIBUTES構造体初期化
    With udtSEQRTY
        .nLength = LenB(udtSEQRTY)
        .lpSecurityDescriptor = 0&
        .bInheritHandle = 0&
    End With

をしないと
lpSecurityAttributes As SECURITY_ATTRIBUTES
で Byref 引数の型が一致しません
とエラーになります。
このエラーを回避する方法としてDeclareでlpSecurityAttributes As Longにする方法があります。
Chip Pearsonはこの方法をとっています。

    ByVal dwCreationDisposition As Long, _

#If VBA7 Then
