Get Window handle from point

[Sinisa]

Hi, first sorry on awkward english.

I'll try to illustrate my problem:
(dont know how will this look on your scrren)

|--Dialog----------------------------------------------------------------------------|
|
|
| |-------groupbox----
-----------------------------------------------------| |
| |
| |
| |
| |
| | |-------------------------------|
| |
| | | Button P(x,y) |
| |
| | |-------------------------------|
| |
| |
| |
| |
| |
|
|-------------------------------------------------------------------------------|
|
|
|
|
|
|-----------------------------------------------------------------------------------------|


P(x,y) represents (point) position of cursor with coordinates x,y
, and that point
lies on button.

Button and groupbox are childs from dialog.

My problem is how to get handle form Button.

i tryed something like:
(this is only part of code)

HWND hwDlg;
HWND hwGroup;
HWND hwButt;

hwGroup = :: WindowFromPoint (p);
/* this is working, i get valid handle*/

hwDlg = ::GetParent(hwG roup);
/* this is also working */

hwButt = ::RealChildWind owFromPoint(hwD lg,p);
/* but here i always get NULL */

as i understand from msdn RealChildWindow FromPoint should return child
handle if
window(in this case button) if point is "over" window , and window is
in transparent area of groupbox .

any advice is most welcome.

You need to ask in a Windows newsgroup. The C+ language knows nothing about
windows or mouse coordinates.

....and we know nothing of the C+ language either! ;-)

I'm developing the C-squared language. A massive project
requiring much energy.

Mike's C-squared = MC^2
Maybe you should just call it E.

That was the point of my joke. (Someone else
has already created 'D').

Ack. Working at the speed of light, and I'm
still too late. :-)
