  If it's your own application you could write Application.OnMessage event and catch all events their. Then create a query of messages and as soon as it is allowed just resend them again.
  If you wish to prevent all applications from getting messages you probably need a windows hook that will work the same way(See SetWindowsHookEx in MSDN).

I wonder what you've meant. Do you consider only your own application
messages or all running ones?
There are many ways to treat messages: install an message hook for any
window in the system, or simply use Application.OnMessage or write your own
TMyForm.ProcessMessages, etc, etc. But it may be complicated.
Normally, in sigle-thread application, messages are not procesed inside
event handlers,
so I don't understand why you want to stop somethig that is not happening at
all.
Please explain, what do you exactly want.
