WM_KETDOWN = 256 번이더군요. System.Console.WirteLine(m.LParam.ToInt32()); // 이걸로 F1 부터 여러가지 키를 차례데로 눌러본 값들이 if( m.LParam.ToInt32() == 3866625 ) // F1 Key // <=== 이 값들입니다. 3866625 가 F1 이군요.. 이런식으로 Key 값을 찾아서 { // 계속 추가하면 키보드 후킹.. 그다지 어려운건 아닐거 같군요 ^^;; System.Console.WriteLine("F1 Press"); return true; } else if( m.LParam.ToInt32() == 3932161 ) // F2 Key { System.Console.WriteLine("F2 Press"); return true; } else if( m.LParam.ToInt32() == 3997697 ) // F3 Key { System.Console.WriteLine("F3 Press"); return true; } break; } return false; } } // // 만들어 놓은 MessageFilter 는 반드시 AddMessageFilter 메서드를 통해 추가해줘야 합니다. // static void Main 함수는 기본 Form 에 포함되어 있습니다. :) 아시죠? static void Main() { Application.AddMessageFilter(new MessageFilter()); Application.Run(new JapExamples()); } 아래 있는 것은 windows.h 파일에 정의된 windos message 들입니다. windows.h 파일은 visual studio 안에 INCLUDE_ROOT 에 있습니다. 어딘지는 아시죠?
