I suspect the confusion is because there is no WM_CLICK, but rather
button-specific up/down messages:

Public Const WM_LBUTTONDOWN = &H201
Public Const WM_LBUTTONUP = &H202
Public Const WM_LBUTTONDBLCLK = &H203
Public Const WM_RBUTTONDOWN = &H204
Public Const WM_RBUTTONUP = &H205
Public Const WM_RBUTTONDBLCLK = &H206
Public Const WM_MBUTTONDOWN = &H207
Public Const WM_MBUTTONUP = &H208
Public Const WM_MBUTTONDBLCLK = &H209

There are also various control-specific notification messages (sent to
a control's parent) such as.
Public Const BN_CLICKED = 0

Documentation for all these and more can be found in MSDN on-line.
Here's the page for WM_LBUTTONDOWN including all the info on the
parameters:

thanks
i found out what was confusing me
if you do a search on wm_click in google you find lots of pages
then i found this chinese site where amongst all the chinese signs there was
WM_CLICK=&HF5
so what some people call wm_click is just BM_CLICK
