GUIOnEventMode, Const question

[Dolemite50]

Hi,

Bear with me if I ask something stupid here.

From what I've read in the manual, it seems like GUIOnEventMode would be a good choice for an application such as a toolbar where you'll be expecting alot of idle time. Is that right? If so, is there any way of defining events from an ActiveX control that is simply calling local functions? I guess I'm asking if there is any sort of windows message sent when an ActiveX control broadcasts a function back to my au3 app.

Also, I've been reading up on Larry's hook program and it seems like it might be an even better alternative, but I don't want to start trying to wrap my head around it if I'm barking up the wrong tree. Has anybody dabbled in it enough to tell me if it would be a good choice to use for a toolbar?

And lastly; I'm still confused about some constants I've seen.

When I see a statement such as this:

Global Const $WS_POPUP = 0x80000000

Is that somehow defining a variation of the default $WS_POPUP behaviour? I'm guessing that the hex consts are referring to items more related to WindowsOS than Autoit. If that's the case, does anybody know where I can read more about them?

...another Const that I'm confused by:

Global Const $GUI_EVENT_CLOSE = -3

Thanks alot for any tips or advice.
