Accessのさんぷるコードができましたので(´Д｀)貼っときます。

Logging

突貫工事で作ったのでバグは多少あると思いますが{例えばsql インジェクション対策とか。}、Accessのsampleコードができましたので貼っときます。なお、これで何が出来るかって言えばDBの修正、追加、削除といった基本的な動きをします｛挙動不審ぎみ嘘！？｝。若干、ソースコードを弄くれば使い回しが出来るようにしております。飯くったり他のことをしながらもガリガリとコードを書きました。ちなみにAccessのViewerをマイクロソフトからダウンロードすると動作すると思います。ファイルは下記からダウンロードください。 追記：暇な時に改良していきますので( ﾟдﾟ)ﾉ ﾖﾛｼｸとコメントも暇があれば書いときます。そして無駄なコードがありますが、それも軽量していくつもりです(｀・ω・´)。ちなみにいまはDBを空にすると落ちますので・・・・（直しました。）。?samplezip358.zip?[https://zip358.com/tool/samplezip358.zip][08/21 11:26]
