_WinAPI_GetDlgCtrlID returns 10000 on _GuiCtrlListView_Create

[GtaSpider]

Hey,

I've noticed that _GuiCtrlListView_DeleteAllItems is very slow. After some researches i found out that the function is only slow on native Controls (GuictrlListviewCreate) but very fast on _GuiCtrlListView_Create. To check whether it's a native control or not the function uses _WinAPI_GetDlgCtrlID. If the return of that function is true (not Zero) then its a native control.

But when i use _GuiCtrlListView_Create the function _WinAPI_GetDlgCtrlID Returns allways 10000 for CtrlId. This is wrong, it shall return Zero.

I use the latest AutoIt Version (3.3.12.0) and tested it also with the beta (.19). I use Win8.1 and tested it also with Win7, same result!

Do you have the same issue?  Is it a Bug or is it just me?

Here is a code you can test with

#include <GuiListView.au3>
#include <WinAPI.au3>


$hGui_Main = GUICreate("")
$hListView1 = GUICtrlCreateListView("blegh",150,0)
$hListView2 = _GUICtrlListView_Create($hGui_Main,"blegh",0,0)
$hListView3 = _GUICtrlListView_Create($hGui_Main,"blegh",0,150)

GUISetState()

MsgBox(0,"",_WinAPI_GetDlgCtrlID(GUICtrlGetHandle($hListView1)));Returns 3 - this is correct!
MsgBox(0,"_GUICtrlListView_Create",_WinAPI_GetDlgCtrlID($hListView2));Returns 10000 - this is wrong!
MsgBox(0,"_GUICtrlListView_Create",_WinAPI_GetDlgCtrlID($hListView3));Returns 10001 - what the heck?

Thanks in Advance,

Spider

Why is it wrong? GetDlgCtrlID isn't an AutoIt control ID, it's a Windows control ID.

Also, _GUICtrlListView_Create uses this line to get that Windows Control ID.

Local $nCtrlID = __UDF_GetNextGlobalID($hWnd)

GtaSpider,

The ControlID used by AutoIt for native created controls is actually an index to an internal array which details the specific control and its properties. The ControlID set by UDF-created controls can be any value at all as the control is not created by AutoIt and so is not part of the internal array. Hence the values you see returned.

However, I take your point about the _GuiCtrlListView_DeleteAllItems function - I will look into how it might be recoded (yet again!).

GtaSpider,

Looking more deeply into how the UDF-created controls get their ControlID I see that there is an internal count which begins at 10000 - so all that needs to be done is to check that the value returned by _WinAPI_GetDlgCtrlID is over or above that value. Thanks for noticing the problem - it will be fixed in the next release.

Hey BrewManNH, hi Melba23,

Ah okay, I see. So it's a bug in the Delete function, something like this would fix it:

;...GuiListView.au3
If $vCID And $vCID < 10000 Then

These functions are also affected by this:

_GUICtrlListView_DeleteItem

_GUICtrlListView_DeleteItemsSelected

Thanks a lot for the fast Support

Greetings,

Spider

Edit: hehe, you were a little bit faster ;-)

GtaSpider,

Fixes committed to all 3 functions - thanks again.

Spider,

The 10000 is basically $_UDF_STARTID in UDFGlobalID.au3. As for why it's 10000, I can't really say as I didn't create that UDF.
