ひさびさのぶろぐ投稿です。
皆様、お元気でしょうか。ワタシはまた入院していましたｗ
VB.NET には過去との互換性の目的も含めて（たぶん）言語固有の関数があります。
それらを VB 関数ではなく、.NET で実装してみようという試みです。
（ほとんど Reflector のお世話になりっぱだと思いますがｗ）
VB 関数が嫌いじゃ～でも VB 関数の機能は使いたいんじゃ～といういるかいないか解らない人向けです。
変換ツールとか使えば、 C# でも VB 名前空間を Import しなくても、VB 関数みたいな事ができる、、、はず、、、
最初は
AppActivate 関数 です。
いきなりこけてますけども、ProcessID を引数にするやつがワタシの環境ではこけてしまいます。
どうも GetWindowThreadProcessId がうまくいっていないっぽい。
