combobox $cbs_dropdownlist value changed when hovered

Aelc · August 11, 2019

Hey there,

I have got a problem with a Combobox with $CBS_DROPDOWNLIST Style...

If i read it in a while for adding another year the value of the combobox is already changed if "add" is hovered and the inputbox appears, but i want it even when i pressed on "add"

any suggestions?

#include <GUIConstantsEx.au3>
#include<ComboConstants.au3>
    $GUI = GUICreate("blah", @DesktopWidth-200, @DesktopHeight-100, -1, -1)
    $YEAR_LABEL_1 = GUICtrlCreateLabel("year",(@DesktopWidth-200) / 2 - 120 , 8,60, 32)
    $year_combo = GUICtrlCreateCombo(@YEAR ,(@DesktopWidth-200) / 2 - 50 , 5, 80, 32, $CBS_DROPDOWNLIST )
    GUICtrlSetData (-1,"2018|2017|add" )
        GUISetState(@SW_SHOW, $GUI)

    While 1
    If GUICtrlRead ( $year_combo ) = "add" Then InputBox("new","","" )
    $nmsg = GUIGetMsg ()
    Switch $nmsg
        Case $GUI_EVENT_CLOSE
            Exit
        Case $YEAR_LABEL_1
    EndSwitch
    WEnd

@Aelc

You need a WM_COMMAND handler which captures the Notification Code $CBN_SELENDOK

Yea i'm actually trying, but i fail to get the text. I just see in the helpfile:

Quote

Remarks

If the message is sent to a ComboBox with the $CBS_DROPDOWN or $CBS_DROPDOWNLIST style the Function will fail.

So how can i get it ?

#include <GuiComboBox.au3>
#include <GUIConstantsEx.au3>
#include <MsgBoxConstants.au3>
#include <WindowsConstants.au3>
#include <GuiComboBoxEx.au3>

    $hGUI = GUICreate("(UDF) ComboBox Create", 400, 296)
    $g_hCombo = _GUICtrlComboBox_Create($hGUI, "2019|2018|2017|add", 2, 2, 396, 296,$CBS_DROPDOWNLIST)
    GUISetState(@SW_SHOW)
    GUIRegisterMsg($WM_COMMAND, "WM_COMMAND")
    Do
;~  MsgBox ( 64,"",GUICtrlRead ( $g_hCombo ) & @CRLF & _GUICtrlComboBox_GetEditText ( $g_hCombo ) )

So complicated - what the hell :hyper: so sad i can't use simply

_GUICtrlComboBox_GetEditText ( $g_hCombo )

well but i got it

#include <GuiComboBox.au3>
#include <GUIConstantsEx.au3>
#include <MsgBoxConstants.au3>
#include <WindowsConstants.au3>
#include <GuiComboBoxEx.au3>
Global $g_hCombo

Func Example()
    Local $hGUI

    ; Create GUI
    $hGUI = GUICreate("(UDF) ComboBox Create", 400, 296)
    $g_hCombo = _GUICtrlComboBox_Create($hGUI, "2019|2018|2017|add", 2, 2, 396, 296,BitOR($CBS_DROPDOWNLIST,$CBS_SORT ))
    GUISetState(@SW_SHOW)
    GUIRegisterMsg($WM_COMMAND, "WM_COMMAND")
    Do
    Until GUIGetMsg() = $GUI_EVENT_CLOSE
    GUIDelete()
EndFunc   ;==>Example

Func WM_COMMAND($hWnd, $iMsg, $wParam, $lParam)
    #forceref $hWnd, $iMsg
    Local $hWndFrom, $iIDFrom, $iCode
    $hWndFrom = $lParam
    $iIDFrom = BitAND($wParam, 0xFFFF)
    $iCode = BitShift($wParam, 16)
    Switch $hWndFrom
        Case $g_hCombo
            Switch $iCode
                Case $CBN_SELENDOK
                    $sText = _GUICtrlCombobox_GetCurSel ( $g_hCombo )
                    $count = _GUICtrlComboBox_GetCount ( $g_hCombo )
                    If $sText = $count -1  Then
                        $new = InputBox ( "","" )
                        _GUICtrlComboBox_BeginUpdate ( $g_hCombo )
                        _GUICtrlComboBox_AddString ( $g_hCombo,$new )
                        _GUICtrlComboBox_EndUpdate ( $g_hCombo )
                    EndIf

            EndSwitch
    EndSwitch
    Return $GUI_RUNDEFMSG
EndFunc   ;==>WM_COMMAND

that works for me as long i have the $CBS_SORT Style...

Thank You

Use _GUICtrlComboBox_GetLBText() instead of the For...Loop:

Hmm your script looks like an easier way

but it doesn't delete the add string and there are multiple 'add' strings in the combo in my test . I actually don't even know why because there is already a _deletestring...

this works in my test :

#include <GuiComboBox.au3>
#include <GUIConstantsEx.au3>
#include <MsgBoxConstants.au3>
#include <WindowsConstants.au3>
#include <GuiComboBoxEx.au3>
#include <FontConstants.au3>

    GUICtrlSetFont(-1, 20, 1200, 0, "Arial", 5)
    $g_hCombo = _GUICtrlComboBox_Create($hGUI, "2019|2018|2017|add",70, 4, 100, 296,$CBS_DROPDOWNLIST)

But at least it doesn't really matter because i have to sort it - it shall be chronological.

I'm trying now, to get the same font on it like my label that stands before. And it's actually a header in my main GUI

And because GUICtrlsetfont don't work i have to _winapi_createfont right? or is there another way ? i mean it works but it takes a long time to adjust the font and compare them....

Still thank you
