Re: Hooks

I need to monitor the following messages.

Button/EditBox /etc... Messages Simply All control Messages.
Regular Window Messages.
Common Control Messages.
DialogBox Messages
DialogBox/Messages Box Notifications (Example while entering text in editbox
it is popping a message box in the middle - I need to catch this also)

For what? The hook type depends on what type of messages you want to

No. That ID identifies the thread which created that window.
That's
all. If additional threads create other windows, you need to get those
IDs
separately.

ok I agree.
But GetWindowThreadId returns one ThreadId
Is that thread id is possible for these concept (all child windows of
Internet Explorer)?

Consider In this Example targeted Window is Internet Explorer
Window.

If I set Hook for Internet Explorer Window.

Shall I able to Catch all the message of the all child windows?

Is it possible to monitor messages of the Combo Box (which is
child of
Internet Explorer )?

I need to monitor all the message related to the all child
windows?

I told here only one child window
But it may be any number of child windows ?

Is it necessary to set hook for each seperate child window?

or
Targeted window is enough for hook ?

I need to log all the child windows data changes ( when message
occurs
data
will change. so i need to log event and data)

Windows hooks are not window specific, they are thread specific.
When
you set a hook on Internet Explorer, you are probably setting a hook
on
the
thread which created the main IE window. Your hook handler will
intercept
all messages (of the type for the specific hook) to that thread. If
a
different thread creates a child window, your hook handler will not
intercept its messages.
