Custom Query

Hiho,

again and again I stumble over this variable :). I often use the example 1 as a simple copy&paste starting point for testing.

Now the button control is labeled $idOK, which is also used in <MsgBoxConstants.au3> as a return value.

It's not a problem in local scope, but I often remove the function definition and then $idOK is suddenly in Global scope and collides with the messagebox const.

I would like to propose to rename the variable in the GUICreate() example into something like $c_Button_OK.

Best Regards

Issue reported by user Nop72 in this Forum link : ​https://www.autoitscript.com/forum/topic/208604-_guictrltab_getitem-fails-to-retrieve-item-text-since-autoit-version-33160/

Basically, it seems that these 2 lines were working fine in AutoIt 3.3.14.5 :

GuiTab.au3 (3.3.14.5)

Func _GUICtrlTab_GetItem($hWnd, $iIndex)
    ...
    Local $tagTCITEMEx = $tagTCITEM & ";ptr Filler" ; strange the Filler is erased by TCM_GETITEM : MS Bug!!!
    Local $tItem = DllStructCreate($tagTCITEMEx)
    ...
EndFunc

Now the changes made in AutoIt 3.3.16.0 creates an issue (tab text isn't retrieved any more) :

GuiTab.au3 (3.3.16.0 , 3.3.16.1-rc1 , 3.3.16.1-rc2)

Func _GUICtrlTab_GetItem($hWnd, $iIndex)
    ...
;~  Local $tagTCITEMEx = $tagTCITEM & ";ptr Filler" ; strange the Filler is erased by TCM_GETITEM : MS Bug!!!
    Local $tItem = DllStructCreate($tagTCITEM)
    ...
EndFunc

The shown code will result in a "AddOne() called with Const or expression on ByRef-param(s)" error. The two other arrangements of the same code will not result in this error, and if you disable Au3Check entirely, the code will run fine. So its an Au3Check-only problem, AutoIt itself is fine with it.
