Caveats
You should remember that this hook intercepts sent messages only. During the modal loop, no messages can be posted to the thread’s message queue.
Some additional MSGF_ messages are defined in
Winuser.h, but this hook does not currently
implement them. These messages are listed here:
Public Const MSGF_MAINLOOP = 8 'Not used with MsgFilter Hook Public Const MSGF_MAX = 8 'Not used with MsgFilter Hook Public Const MSGF_MESSAGEBOX = 1 'Not used with MsgFilter Hook Public Const MSGF_MOVE = 3 'Not used with MsgFilter Hook Public Const MSGF_SIZE = 4 'Not used with MsgFilter Hook Public Const MSGF_USER = 4096 'Not used with MsgFilter Hook Public Const MSGF_NEXTWINDOW = 6 'Not used with MsgFilter Hook
Even though this hook intercepts a subset of the messages that hooks
such as WH_CALLWNDPROC or
WH_CALLWNDPROCRET intercept, you should still
watch how this hook affects your application’s performance.
