public class Win32Hook
{
[DllImport("kernel32")]
public static extern int GetCurrentThreadId();
[DllImport( "user32",
CharSet=CharSet.Auto,CallingConvention=CallingConvention.StdCall)]
public static extern int SetWindowsHookEx(
HookType idHook,
HOOKPROC lpfn,
int hmod,
int dwThreadId);
public enum HookType
{
WH_KEYBOARD = 2
}
public delegate int HOOKPROC(int nCode, int wParam, int lParam);
public void SetHook()
{
// set the keyboard hook
SetWindowsHookEx(HookType.WH_KEYBOARD,
new HOOKPROC(this.MyKeyboardProc),
0,
GetCurrentThreadId());
}
public int MyKeyboardProc(int nCode, int wParam, int lParam)
{
//在這裏放置妳的處理代碼 return 0;
}
}
使用方法
可以在Form的構造函數裏放入
Win32Hook hook = new Win32Hook();
hook.SetHook();
