Need help with _GUICtrlComboBox_AutoComplete

4 posts in this topic

I'm trying to create a combo box populated with email addresses, and I'd like for the matching email address to autocomplete when typing into the box. I found the code below in the help files, but I'm still lost on how to implement it. I'd prefer to be able to make a single function call to make the combo box rather than include all the code below. Any suggestions would be greatly appreciated.

#AutoIt3Wrapper_au3check_parameters=-d -w 1 -w 2 -w 3 -w 4 -w 5 -w 6
#include <GUIComboBox.au3>
#include <GuiConstantsEx.au3>
#include <WindowsConstants.au3>

Opt('MustDeclareVars', 1)

$Debug_CB = False; Check ClassName being passed to ComboBox/ComboBoxEx functions, set to True and use a handle to another control to see it work

   ; Add files
    _GUICtrlComboBox_BeginUpdate($hCombo)
    _GUICtrlComboBox_AddDir($hCombo, @WindowsDir & "\*.exe")

Here it is reduced. Maybe it helps.

#include <GUIComboBox.au3>
#include <GuiConstantsEx.au3>
#include <WindowsConstants.au3>

Opt('MustDeclareVars', 1)

Global $hCombo


 ; Create GUI
    GUICreate("ComboBox Auto Complete", 400, 296)
    $hCombo = GUICtrlCreateCombo("", 2, 2, 396, 296)
    GUISetState()

 ; Add files
    _GUICtrlComboBox_BeginUpdate($hCombo)
    _GUICtrlComboBox_AddDir($hCombo, @WindowsDir & "\*.exe")
    _GUICtrlComboBox_EndUpdate($hCombo)

    GUIRegisterMsg($WM_COMMAND, "WM_COMMAND")

 ; Loop until user exits
    Do
    Until GUIGetMsg() = $GUI_EVENT_CLOSE
    GUIDelete()



Func WM_COMMAND($hWnd, $iMsg, $iwParam, $ilParam)
    #forceref $hWnd, $iMsg
    Local  $iCode, $hWndCombo
    If Not IsHWnd($hCombo) Then $hWndCombo = GUICtrlGetHandle($hCombo)

Serial port communications UDF Includes functions for binary transmission and reception.printing UDF Useful for graphs, forms, labels, reports etc.Add User Call Tips to SciTE for functions in UDFs not included with AutoIt and for your own scripts.Functions with parameters in OnEvent mode and for Hot Keys One function replaces GuiSetOnEvent, GuiCtrlSetOnEvent and HotKeySet.UDF IsConnected2 for notification of status of connected state of many urls or IPs, without slowing the script.
