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(hwGroup);
/* this is also working */

hwButt = ::RealChildWindowFromPoint(hwDlg,p);
/* but here i always get NULL */

as i understand from msdn RealChildWindowFromPoint 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.

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

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

E already exists. http://en.wikipedia.org/wiki/E_programming_language

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. :-)
