Refresh Combo Box after first combo box option changes

4 posts in this topic

Ive got two combo box's, the first one you select the folder, and the second one lists all the folders within that folder for you to select from.

How can I get the second combo to rescan when I change select of the first one?

This is what ive got at the moment, I just need it to update the list if I change my folder selected in the first combo.

$Folder = GUICtrlCreateCombo("C:\Folder1", 142, 122, 435, 22, BitOR($CBS_DROPDOWN,$CBS_AUTOHSCROLL))
GUICtrlSetData(-1, "C:\Folder2")

Local $folderselector = GUICtrlRead($Folder)


If $folderselector = "C:\Folder1" Then
Local $FileList = _FileListToArray("C:\Folder1")
_ArrayDelete($FileList, 0)
$sFileList = _ArrayToString($FileList, "|")
Else
$folderselector = "C:\Folder2" Then
Local $FileList = _FileListToArray("C:\Folder2")
_ArrayDelete($FileList, 0)
$sFileList = _ArrayToString($FileList, "|")

EndIf

ok so already found an issue with my code, updated it to this but still dunno how to refresh:

$Folder = GUICtrlCreateCombo("C:\Folder1", 142, 122, 435, 22, BitOR($CBS_DROPDOWN,$CBS_AUTOHSCROLL))
GUICtrlSetData(-1, "C:\Folder2")

Local $folderselector = GUICtrlRead($Folder)


If $folderselector = "C:\Folder1" Then
Local $FileList = _FileListToArray("C:\Folder1")
_ArrayDelete($FileList, 0)
$sFileList = _ArrayToString($FileList, "|")
Else
Local $FileList = _FileListToArray("C:\Folder2")
_ArrayDelete($FileList, 0)
$sFileList = _ArrayToString($FileList, "|")

EndIf

cookiemonster,

Just wait until there is a selection in the first combo and then update the second: ;)

#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>
#include <Constants.au3>
#include <ComboConstants.au3>
#include <Array.au3>
#include <File.au3>

Global $sAutoItDir = StringLeft(@AutoItExe, StringInStr(@AutoItExe, "\", Default, -1))
If StringRight($sAutoItDir, 5) = "beta\" Then
    $sAutoItDir = StringTrimRight($sAutoItDir, 5)
EndIf

$hGUI = GUICreate("Test", 500, 500)


$cCombo_1 = GUICtrlCreateCombo("", 10, 50, 230, 20, BitOR($CBS_DROPDOWNLIST, $CBS_AUTOHSCROLL, $WS_VSCROLL))

$cCombo_2 = GUICtrlCreateCombo("", 260, 50, 230, 20, BitOR($CBS_DROPDOWNLIST, $CBS_AUTOHSCROLL, $WS_VSCROLL))

GUISetState()

$aList_1 = _FileListToArray($sAutoItDir, "*", 2)
GUICtrlSetData($cCombo_1, "|" & _ArrayToString($aList_1, "|", 1))

While 1

    Switch GUIGetMsg()
        Case $GUI_EVENT_CLOSE
            Exit
        Case $cCombo_1
            $sPath = $sAutoItDir & "\" & GUICtrlRead($cCombo_1)
            $aList_2 = _FileListToArray($sPath, "*", 2)
            GUICtrlSetData($cCombo_2, "|" & _ArrayToString($aList_2, "|", 1))
    EndSwitch

WEnd
Does that do the trick? :)
