Combobox functions does not work properly or even at all, on Windows 2000 & NT 4.0

[crzmeister@…]

Hello,

I'll refer to two different combobox functions which malfunction on Windows 2000 (sp4 2195) and NT 4 (sp6a).

First one is: _GUICtrlComboBoxEx_Create

and probably derivatives (i mean same type of functions). When compiled to run on the above mentioned OSes, the script/exe throws an error on start "Error: _WinAPI_CreateWindowEx: Cannot find window class."

This *does not* happen on Windows XP or 2003.

I found it through my own scripts, but you can reproduce it if you compile the example script under the _GUICtrlComboBoxEx_Create section of AutoIT's .chm help file. and run in on the reported OSes.

Second one is: (the regular) GUICtrlCreateCombo.

Again problem is on Windows 2000 (2195). I was not able to test on NT 4.0 . Here follows example code:

#include <GuiConstantsEx.au3>

Opt('MustDeclareVars', 1)

_Main()

Func _Main()
	Local $msg, $hGUI, $combobox
	
	$hGUI = GUICreate("Title", 250, 173)
	GUICtrlCreateLabel("Label that bugs the app on Win2k:", 2, 3)
	$combobox = GUICtrlCreateCombo("1", 2, 20, 244)
	GUICtrlSetData($combobox, "2|3|4|5")
	GUISetState()
		While 1
        $msg = GUIGetMsg()
        Switch $msg
            Case $GUI_EVENT_CLOSE
                ExitLoop			
			EndSwitch
		WEnd
		
EndFunc

What it does is that the combobox does not drop down at all. If I will comment the line to create label (;GUICtrlCreateLabel("Label:", 2, 3)), it works as expected on XP/2003 and 2000.

For your first issue, it's obvious the ComboBoxEx control is not implemented on the OS you are trying to use. ComboBoxEx is not the same thing as a ComboBox.

As for your second issue, read the documentation, I'll be you find your answer. Try looking at the Remarks section of GUICtrlCreateCombo().

No bugs to see here.

Well, I can agree with this explanation, but what does it mean "is not implemented on the OS you are trying to use"? I'm using on standard 2k/NT4 latest updates. I suppose it should be written in docs "Notice: It doesnt work there", but it is not.
