发送密钥正在禁用NumLock

Question

问题：

当我使用SendKeys将数据从Excel应用程序复制到另一个（非Microsoft）应用程序时，我的Num Lock将被禁用。

Sub Test()

    Range("A1:B71").Select
    SendKeys "^C" 'Copies Selected Text

    AppActivate "AccuTerm 2K2"
    SendKeys "2", True    'Enters to notes screen
    SendKeys "^M", True   'Confirms above (Enter key)
    SendKeys "^V", True   'Pastes into client application

    Application.Wait (Now + TimeValue("0:00:05"))
    'Providing time for client application to finish
    'pasting...

    SendKeys "^M", True   'Next three enters are to
    SendKeys "^M", True   '...exit notes section
    SendKeys "^M", True
    AppActivate "Microsoft Excel"

    Range("B52:B62").Clear  'Clears the Template
    Range("B52").Select     'Resets Cell Position

End Sub

首选解决方案：

可以采取哪些措施来阻止我的代码禁用NumLock - 或者如何在代码完成后重新启用numlock？

Answer 1

使用此功能重新打开numlock。我忘记了我在互联网上找到这个的地方。我没有创作。

  

NumLockClass

将其放在课程模块中。

使用它像：

Dim numLock As New NumLockClass
If numLock.value = False Then numLock.value = True  'turn it back on
