Retrieve ContolID from a window.(any win)

[Amen]

From Autoit Help file:

"GUIGetCursorInfo ( [winhandle] )

..

$array[4] = ID of the control that the cursor is hovering over (or 0 if none)

..

The mouse cursor position is successfull only on an active window created by a GUICreate."

Autoit info tool can retrive any control ID of Control Under Mouse..

>>>>>>>>>>> Control Under Mouse <<<<<<<<<<<

Size: X: 0 Y: 90 W: 760 H: 362

Control ID: 11

ClassNameNN: SysListView321

Text:

ExStyle: 0x00000200

My prog cannot.Can anyone helps me? To do the same thing without Using the Autoit Info tool?

I really wanted to know it too. I think it's something with the WinAPI functions:

GetCursorPos

WindowFromPoint

ChildWindowFromPoint

While 1
$p = DllStructCreate("int;int")
$pet = DllCall("user32.dll", "int", "GetCursorPos", "ptr", DllStructGetPtr($p))
$set = DllCall("user32.dll", "int", "WindowFromPoint", "int", DllStructGetData($p,1),"int",DllStructGetData($p,1))
;$set = DllCall("user32.dll", "int", "ChildWindowFromPoint", "hwnd", $WinNow, "int", DllStructGetData($p,1),"int",DllStructGetData($p,1))
TrayTip("", $set[0], 5, 16)

Sleep(1)
WEnd

Hope you will find it out

Truthfully, I don't know what you are asking, but maybe this will help.

It works now quite nice, only sometimes highlights strange things...

Hi , am unable to understand this as what would be the output... its supposed to provide the position of caret right?
