はじめに

色々調べたけどズバリの情報がなかなかなく、自分で試行錯誤した内容の忘備録として
同様のことをやっている人やもっと便利な方法があればどんどん取り入れて行きたい
という思いで記事を書きました

環境・前提

（当たり前ですが）Windows 10 or later, Windows Server 2016 or later
- Windows７の頃からやってましたがMicrosoftのサポートが終了したので
Microsoft Office 365 Access2019 32bit版(64bitは考慮しません)
神ツールVBAC.wsfを自分の環境に合わせてカスタマイズしました
大文字アルファベットを小文字に変換する独自アプリを作成

運用環境を用意するまでの経緯

MsAccessのバージョン2007から2010まではVSS(Visual Source Safe)ソース管理アドインがMicrosoftから提供されていました
しかし次のMsAccess2013からVSSアドインに見放される・・・
前述のVBAC.wsfという神ツールを開発している神がいたので使わせてもらう
- VBAC.wsfを使うことでmdb/accdbの中身をテキストファイルとして出力することができる
- テキスト化出来ればあとはそれをGITにぶっこむだけ。
- 世界に平和が訪れたかに見えたが・・・

VBAの仕様により変数名のアルファベットの大文字小文字がコロコロ変わる

変数名の大文字小文字は実行時に区別されない（同一視される）
その為同一変数名のCase（大文字小文字）を変更するとmdb/accdb全体の変数が変わる
例えばModule1とModule2があるとして・・・

(Module1)
Function GetData() As String
 Dim strValue as String
 ' 何らかの処理〜
End Function

(Module2)
Function SetData(byVal param As String) 
 Dim strValue as String
 ' 何らかの処理〜
End Function

複数人開発で他の人がModule2の変数strValueをStrValue(先頭のSが大文字)に書き直したとするとModule2だけでなくModule1、更にはmdb/accdbに含まれる全てのコード上のstrValueがStrValueと置き換わってしまう
（VBAでは変数名の大文字小文字は無視されるため）プログラム実行上は何の問題なく動くがGIT管理上は非常にやりにくい
- 大文字小文字が変わっただけで差分として抽出されるので、ちゃんとした修正内容がわかりにくい。

大文字小文字を無視する方法を探す

GITの設定で大文字小文字の差分を無視するものがないか調べてみた。
- が勿論なかった。（そらそうや）
- ググると
  - 「ファイル名」の大文字小文字についての結果が出てくるが、肝心のファイルの中身の大文字小文字を無視するものはない
  - 「そもそもMsAccessなんて使うのが間違い・・・」いや、こっちも好きで使ってるわけじゃない
某コミュニティで知恵を借りるも「複数人で開発するならコーディング規則を決める」などで、既に10数年に渡るサグラダ・ファミリアmdb/accdbプロジェクトには適応出来ない

アルファベットを小文字に変換する独自アプリを作成する

神ツールVBAC.wsfで一旦テキスト出力した後、全部小文字に置き換えれば万事解決やとやってみた。

しかし、小文字にしてはまずい文字列もある

SQL文のテーブル名、カラム名等
- 大文字小文字を区別するデータベースがほとんどではないでしょうか。
~~Win32Api関数の宣言部分~~
- ~~こういうのです↓　 FunctionとLibの間にある文字列が小文字になると実行時に動いてくれない~~

reportとformのデザイナ部分
- reportとformはプログラムだけではなく、テキストボックスやボタンなどのコントロールのサイズや位置などを表したテキストがびっしり出力されます

'form の出力例
Version =21
VersionRequired =20
PublishOption =1
Begin Form
    DividingLines = NotDefault
    AllowDesignChanges = NotDefault
    DefaultView =0

    RecSrcDt = Begin

    End
    GUID = Begin
        0xa3e97a8a9540174e8e13bf19e3486078
    End
    OnOpen ="[Event Procedure]"
    DatasheetFontName ="ＭＳ Ｐゴシック"
    PrtMip = Begin
        0x6801000068010000680100006801000000000000201c0000e010000001000000 ,
        0x010000006801000000000000a10700000100000001000000
    End
    PrtDevMode = Begin
        0x007c7477000000000000000000000000000000000000d8012896631e64504e00 ,
        0x010403069c00540353ef8001010009009a0b3408640001000f00b00402000100 ,

'(以下省略)

これらは小文字に変換してしまうと復元が出来なくなる

なのでこれらを満たすアプリを独自開発

C#で実装
当時入社間もなかった後輩さんに研修課題として実装して頂きました。

VBAC.wsfのテーブルオブジェクトについて

MsAccessには３種類のテーブルオブジェクトがある
- MsAccessファイル自身の中に作成されたテーブル（一般的なもの）
- リンクテーブル（更に２種類に分岐）
  - MsAccessをデータソースとしたリンクテーブル
  - ODBCをデータソースとしたリンクテーブル
- リンクテーブル情報もGIT管理したかったのでVBAC.wsfを少しカスタマイズした。

カスタマイズしたVBAC.wsf（長いので折りたたみ）

The vbac is not VBA compiler.
Instead, this unsophisticated script frees VBA code from binary files.
This script is distributed as part of the Ariawase library.

カスマクロを削除する

MsAccesssは何かの拍子にカスマクロが出来上がることがあります。
そのカスマクロを削除するプログラムをmdb/accdbで実行してからVBAC.wsfでテキスト出力します
具体例↓

On Error Resume Next
DoCmd.deleteobject acmacro, "~TMPCLPMacro"
DoCmd.deleteobject acmacro, "~TMPCLP351141"
DoCmd.deleteobject acmacro, "~TMPCLP351451"
DoCmd.deleteobject acmacro, "~TMPCLP351771"
DoCmd.deleteobject acmacro, "~TMPCLP352081"
On Error GoTo 0

カスマクロの名前はランダムなように見えますが、これまで運用してきた中この５パターンか絞られました。
- この５つ以外の名前のカスマクロには数年お目にかかってません。
カスマクロはmdb/accdbのデータベースウィンドウでは非表示になっている為出来上がっていることに気づけません。
VBAC.wsfでマクロも出力できますが、このカスマクロ達がmdb/accdb内部にいると出力されなくなり、インポートできなくなってしまいます。

VBAC.wsfをダブルクリックで起動で来るバッチを作成

cscript //nologo vbac.wsf decombine /binary:

mdb/accdbと同一フォルダに配置すれば自動的にテキスト出力してくれる
GIT管理がだいぶやりやすくなりました。

課題

report/ formはデザイナモードで開いて何も変更せず保存してしまうと、テキスト出力時に差分が出てしまう
mdb/accdbにメニューを追加したり、参照設定を追加しているので、定期的にmdb/accdbをまるごとcommit&pushする必要がある。
- mdb/accdbまるごとはマージ出来ないので複数人開発の場合、何らしかルールを決める必要がある
