It also says

"Contains information passed to a WH_CBT hook procedure, CBTProc, *before a 
window is created*."

and

"A pointer to a CREATESTRUCT structure that contains initialization 
parameters for the window *about to be created*."

and

"It is possible to send messages to *the newly created window*,"

So, we have a Schrödinger's cat window which, in the HCBT_CREATEWND event, 
is at the same time both created and not created ?

Yeah, that really gives me confidence about the correctness/completeness of 
the rest of the provided information. :-(


Also,

"Specifies a long pointer to a CBT_CREATEWND structure containing 
*initialization parameters for the window*."

Which is *at best* vague.  At face value it seems to indicate that *all* of 
those parameters are used.

Which is followed by

"The parameters *include* the coordinates and dimensions of the window."

And pardon me, but as far as I know "include" doesn't translate to "with the 
exclusion of everything else" in *any* language.


Again : do you perhaps have any information, MSDN or otherwise, about which 
fields in that CREATESTRUCT may be changed (are carried on to the resulting 
window) ?

If that information is not available than I will just determine them 
empirically.


And by the way: I just tried to change the Style and ExStyle fields, but 
those also get ignored.
