自分用キーコンあぷり

・・・自分用のwikiなり作っておくべきだったなぁ～(´-`)且~~

自分の家だとソフトで無変換キーをマウスの左クリックに割り当ててるんだけど、今のお仕事先で勝手にネットからソフトを落としてくる事が出来ないので自作。

ソースコードを出先でコンパイルする分には何も言われまい(たぶん)。
低レベルグローバルフック使ってるからセキュリティソフトによっては文句言われるかな～？

作って気づいたけど、.net framework 3 ぐらいで作っておけばVistaなら標準で入ってるしデフォで使えるじゃん・・・
4で作って失敗したかもとか思ったけどメンドイしイイヤ。
3で作ってもVisualStudio2008以上が入ってないとコンパイルデキナイし。

Hookのときにウィンドウメッセージを使ってるからなのかコンソールアプリで作ると動かない。
Threadとは違うと思うしウィンドウズフォームアプリだと動くからWndProc絡みなのかなー
