understanding controlID vs handle

[Burgaud]

$cListView = GUICtrlCreateListView("Column 1|Column 2|Column 3", 5,   2, 590, 200, -1, BitOR($LVS_EX_GRIDLINES, $LVS_EX_FULLROWSELECT))
$hListView = GUICtrlGetHandle($cListView)

$cListView is a controlID

$hListView is a handle

what and how are they different? and why must they be separate/different?

are they array? pointer? pointer to a pointer?

This has been discussed in the past. Here's one example --

 

[Burgaud]

If I understand it correctly:

ControlIDs are index to an array of handles, while handle points to the actual data structure. (more or less).

If there is a GUICtrlGetHandle function, is there a reverse of it? (though not sure If I need it).

; Check handle
If Not IsHWnd($hWnd) Then $hWnd = GUICtrlGetHandle($hWnd)
If Not IsHWnd($hWnd) Then

 

thanks!
