Question

我正在使用AutoIt并希望使用ControlCommand控制组合框。我可以更改值，但是当我跳转到下一个命令时，它将被重置。

我试过几种方法，

但它不起作用。

$hComBo=ControlGetHandle("","","[CLASS:TComboBox; INSTANCE:6]")
$aList = _GUICtrlComboBox_GetListArray($hComBo)
;_ArrayDisplay($aList)
Select
Case $Baudrate=5
    ControlCommand($hWnd,"",$hComBo,"SelectString",$aList[7])
    MsgBox($MB_OKCANCEL," Info ", @error & " - Element: " & $aList[7])
    ;_GUICtrlComboBox_SetCurSel($hComBo,5)
    ;$iCode = $CBN_SELCHANGE
    ;$val = BitShift($iCode, -16)
    ;_SendMessage($hWnd, $WM_COMMAND, $val, $hComBo)
    ;MsgBox($MB_SYSTEMMODAL," Info ", "hWnd: "& $hWnd &"- WM-Command: "& $WM_COMMAND &"- val: " & $val  &"- hComBo: " &$hComBo)
    Sleep(3000)
    ;MsgBox($MB_OKCANCEL," Info ", $baudrate)
EndSelect

Sleep（3000）我可以看到组合框中有正确的值，但在处理完下一个命令后它会消失。有任何想法吗？

有时需要在设置一个列表条目（source）后发送WM_COMMAND消息。但正如MSDN中所述，要发送的$wParam必须同时包含$iCode和Control-ID。

要解决此问题，您可以使用：

$hControl = ControlGetHandle($hExport, "", "[CLASS:ComboBox; INSTANCE:1]") ; get control handle
_GUICtrlComboBox_SetCurSel($hControl, 2) ; select something
$iID = _WinAPI_GetDlgCtrlID($hControl) ; get control ID
$wParam = BitOR($iID, BitShift($CBN_SELCHANGE, -16)) ; put ID and message together

_SendMessage($hExport, $WM_COMMAND, $wParam, $hControl) ; send massage

带控制命令选择的Auto It Combo Box消失
