Why I receive the message twice???

Hello all,
I set a hook 0f WH_KEYBOARD_LL, when it intercept the "Ctrl + F11" will
send message "WM_USER_CTRL_F11" to my program and my program will pop a
message box when it received the message, but I always receive the message
twice, so it always pop 2 message boxes, how to solve it?

Thanks a lot!
