将下一个窗口设置为活动窗口 (ALT+TAB)

Question

我正在使用键盘快捷键运行 vbs 文件。尽管代码运行良好，但 vbs 快捷键的问题是，只要您按下键盘快捷键，前台窗口就会失去焦点。 （您可以通过在某处放置一个空的 vbs 文件、该文件的快捷方式（例如开始菜单文件夹）、分配给该快捷方式的键盘快捷方式并按下键盘快捷方式来亲自尝试。）

我发现通过使用 ALT+TAB，我可以让前景窗口重新获得焦点。但是，我无法在 VBA 中重复此功能。显然，ShellObject.SendKeys("%{TAB}") 不起作用...

有没有办法在VBA中实现ALT+TAB的功能？提前致谢。

编辑

与此同时，我改用 AutoIt 看看它是否能让我走得更远。这是我得到的：

ControlFocus("[CLASS:CabinetWClass]", "", "[CLASS:DirectUIHWND]")

我注意到在某些情况下选择资源管理器窗口（即 CabinetWClass）是不够的。这就是为什么我将重点放在实际包含文件/文件夹的控件上。

它工作得很好，但我仍然希望有一个 VBA 解决方案 :)

您能否使用 Windows API 将其重新置于顶部？当在 Excel 中运行以将记事本置于顶部时，这对我有用，所以它应该可以工作。您必须在 FindWindow 调用中替换您的窗口名称。

注意：你应该非常小心一些标志，因为如果你对它们进行了错误的组合，你会得到一些奇怪的行为。

Public Declare Function FindWindow Lib "user32" _
    Alias "FindWindowA" ( _
    ByVal lpClassName As String, _
    ByVal lpWindowName As String) As Long


Declare Function SetWindowPos Lib "user32.dll" (ByVal hwnd As _
        Long, ByVal hWndInsertAfter As Long, ByVal x As Long, ByVal y As _
        Long, ByVal cx As Long, ByVal cy As Long, ByVal wFlags As Long) As Long

'Either the handle of the window to position this window behind, or exactly one of the following flags stating where in the
'Z-order to put the window:
Private Const HWND_BOTTOM = 1             'Put the window at the bottom of the Z-order.
Private Const HWND_NOTOPMOST = -2         'Put the window below all topmost windows and above all non-topmost windows.
Private Const HWND_TOP = 0                'Put the window at the top of the Z-order.
Private Const HWND_TOPMOST = -1           'Make the window topmost (above all other windows) permanently.

'x: The x coordinate of where to put the upper-left corner of the window.
'y: The y coordinate of where to put the upper-left corner of the window.

'Flags: Zero or more of the following flags stating how to move the window:

Private Const SWP_SHOWWINDOW = &H40           'Show the window if it is hidden.


Sub ShowWindow()
    Dim hwnd As Long 'handle to get the window
    Dim flags As Long ' the flags specifying how to move the window
    Dim retval As Long ' return value

    hwnd = FindWindow(vbNullString, "Untitled - Notepad")
    flags = SWP_NOSIZE Or SWP_DRAWFRAME
    retval = SetWindowPos(hwnd, HWND_TOP, 0, 0, 1, 1, flags) ' move the window

如果您也知道要切换的项目的名称，可以尝试AppActivate 函数，在这种情况下您可能不知道。

否则，试试这个：

SendKeys "%{TAB}", True

Answer 3

ActiveWindow.ActivateNext 和可能类似的可能有用。
