Example()

QUESTION 1:

Why this gives @errors = 1:

ControlGetHandle($hGui, '', $idContextmenu)
    ConsoleWrite('@error = ' & @error& @CRLF & @CRLF)
    ControlGetHandle($hGui, '', $idNewsubmenu)
    ConsoleWrite('@error = ' & @error& @CRLF & @CRLF)

QUESTION 2:
$aMenuInfo[4] = 0x000101F9

Which control have this hwnd

mLipok,

Answers:

- 1. Use GUICtrlGetHandle and you will get the correct handles returned. If you are dealing with AutoIt controlIDs it is always better to use the GUICtrl* functions if available: ;)

Local $idContextmenu = GUICtrlCreateContextMenu()
ConsoleWrite("Context menu ID: " & $idContextmenu & @CRLF)
ConsoleWrite("...handle: " & GUICtrlGetHandle($idContextmenu) & @CRLF)

Local $idNewsubmenu = GUICtrlCreateMenu("new", $idContextmenu)
Local $idNewsubmenuText = GUICtrlCreateMenuItem("text", $idNewsubmenu)

Local $idButton = GUICtrlCreateButton("OK", 100, 100, 70, 20)
Local $idButtoncontext = GUICtrlCreateContextMenu($idButton)
Local $idMenuAbout = GUICtrlCreateMenuItem("About button", $idButtoncontext)
ConsoleWrite("Button menu ID: " & $idButtoncontext & @CRLF)
ConsoleWrite("...handle: " & GUICtrlGetHandle($idButtoncontext) & @CRLF)
- 2. As you have set $iObject to 2, you are asking for the details of the GUI System menu (the one you open by right-clicking the icon at top left). If you look at the GUI coordinates you can see that this is indeed the case as the menu coordinates (shown in the array) are close to the actual GUI coordinates in the console: :)

$aPos = WinGetPos($hGui)
ConsoleWrite("GUI cords: " & $aPos[0] & " - " & $aPos[1] & @CRLF)
Local $aMenuInfo = _GUICtrlMenu_GetMenuBarInfo($hGui, 0, 2)
_ArrayDisplay($aMenuInfo, '$aMenuInfo')

Can you add a new description to helpfile ControlGetHandle.

And link to related ?

mLipok,

It seems only menu items will not return handles via ControlgetHandle - the button is quite happy:

Local $idButton = GUICtrlCreateButton("OK", 100, 100, 70, 20)
ConsoleWrite("Button ID: " & $idButton & @CRLF)
ConsoleWrite("...handle: " & GUICtrlGetHandle($idButton) & @CRLF)
ConsoleWrite("...direct: " & ControlGetHandle($hGUI, "", $idButton) & @CRLF)
I imagine it might well be to do with the fact that the menus are not displayed immediately and so are not associated with the GUI until they are. Perhaps someone else with a deeper knowledge could expand/explain. :huh:

Until there is a definite answer I will not change the help file as you requested - although I will look at finding a place to add the "Use GUICtrl* functions on native controls" advice. ;)
