Reading the edit of a comboboxEx with style $CBS_DROPDOWN and $WS_VSCROLL

[christophamort]

The function _GUICtrlComboBoxEx_GetEditText does not give the inputs content, when called on a comboboxEx with the default style ($CBS_DROPDOWN $WS_VSCROLL). It always returns "".

code from autoit documentation with some changes:

#include <Debug.au3>
#include <GuiComboBoxEx.au3>
#include <GuiImageList.au3>
#include <GuiConstantsEx.au3>

Opt('MustDeclareVars', 1)

$Debug_CB = True ; Check ClassName being passed to ComboBox/ComboBoxEx functions, set to True and use a handle to another control to see it work
ClipPut(_DebugBugReportEnv()) ; my Environment = 3.3.0.0 under  WIN_VISTA/Service Pack 2 X64
_Main()

Func _Main()
	Local $hGUI, $hImage, $hCombo
	
	; Create GUI
	$hGUI = GUICreate("ComboBoxEx Get Edit Text", 400, 300)
	$hCombo = _GUICtrlComboBoxEx_Create ($hGUI, "", 2, 2, 394, 100)
	GUISetState()

	$hImage = _GUIImageList_Create (16, 16, 5, 3)
	_GUIImageList_AddIcon ($hImage, @SystemDir & "\shell32.dll", 110)
	_GUIImageList_AddIcon ($hImage, @SystemDir & "\shell32.dll", 131)
	_GUIImageList_AddIcon ($hImage, @SystemDir & "\shell32.dll", 165)
	_GUIImageList_AddIcon ($hImage, @SystemDir & "\shell32.dll", 168)
	_GUIImageList_AddIcon ($hImage, @SystemDir & "\shell32.dll", 137)
	_GUIImageList_AddIcon ($hImage, @SystemDir & "\shell32.dll", 146)
	_GUIImageList_Add ($hImage, _GUICtrlComboBoxEx_CreateSolidBitMap ($hCombo, 0xFF0000, 16, 16))
	_GUIImageList_Add ($hImage, _GUICtrlComboBoxEx_CreateSolidBitMap ($hCombo, 0x00FF00, 16, 16))
	_GUIImageList_Add ($hImage, _GUICtrlComboBoxEx_CreateSolidBitMap ($hCombo, 0x0000FF, 16, 16))
	_GUICtrlComboBoxEx_SetImageList ($hCombo, $hImage)

	For $x = 0 To 8
		_GUICtrlComboBoxEx_AddString ($hCombo, StringFormat("%03d : Random string", Random(1, 100, 1)), $x, $x)
	Next
	
	; Set Edit Text
	_GUICtrlComboBoxEx_SetEditText ($hCombo, StringFormat("%03d : Random string", Random(1, 100, 1)))
	
	; Get Edit Text
	MsgBox(4160, "Information", "Edit Text: " & _GUICtrlComboBoxEx_GetEditText ($hCombo))
	
	Do
	; Get Edit Text ond dirfferent selections
	MsgBox(4160, "Information", "Edit Text: " & _GUICtrlComboBoxEx_GetEditText ($hCombo))
	Until GUIGetMsg() = $GUI_EVENT_CLOSE
EndFunc   ;==>_Main

That script wins my award for most obnoxious script to reproduce a bug ever invented. I think you could have spent another 30 seconds and added a button and hooked it up to read the text rather than prompting with an obnoxious noise making message box.

time is money!
c.

obnoxious! didn't know that word before, that's worth 100$$.

Here is a shorter and less annoying example:

#include <GuiComboBoxEx.au3>
#include <GuiConstantsEx.au3>

_Main()

Func _Main()
	Local $hGUI = GUICreate("ComboBoxEx Get Edit Text", 400, 300)
	Local $hCombo = _GUICtrlComboBox_Create ($hGUI, "", 2, 2, 394, 100)
	Local $hButton = GUICtrlCreateButton("Read", 4, 150, 50, 25)
	GUISetState()

	For $x = 0 To 8
 		_GUICtrlComboBoxEx_AddString ($hCombo, StringFormat("%03d : Random string", Random(1, 100, 1)), $x, $x)
	Next

	; Setting the edit text fails.
	_GUICtrlComboBoxEx_SetEditText ($hCombo, StringFormat("%03d : Random string", Random(1, 100, 1)))

	While True
		Switch GUIGetMsg()
			Case $GUI_EVENT_CLOSE
				ExitLoop
			Case $hButton
				; Reading the edit text fails.
				MsgBox(4160, "Information", "Edit Text: " & _GUICtrlComboBoxEx_GetEditText ($hCombo))
		EndSwitch
	WEnd
EndFunc   ;==>_Main

I was prepare to answer that is the Way windows work.
I assume Valik found a solution to fix it as it is now in Blocking state.

[Valik]

Blocking means a ticket needs closed before the release, not that anything needs to change. If you are 100% sure this is an intentional Windows limitation that cannot be easily worked around then close the ticket.

Fixed by revision [5340] in version: 3.3.1.5

[Valik]

Just mentioning that this isn't fixed in that it will work. It's only fixed in that it's been documented that it doesn't work. It's a Windows design limitation.
