主题：平板电脑小键盘问题

 全局代码

Public Declare Sub keybd_event Lib "user32" (ByVal bVk As Byte, ByVal bScan As Byte, ByVal dwFlags As Integer, ByVal dwExtraInfo As Integer)
Public Declare Function MapVirtualKey Lib "user32" Alias "MapVirtualKeyA" (ByVal wCode As Integer, ByVal wMapType As Integer) As Integer

Public Const VK_NUMLOCK = &H90 ' Num Lock

Public Const KEYEVENTF_KEYDOWN = &H0 ' KeyDown

Public Const KEYEVENTF_KEYUP = &H2 ' KeyUp

 触发代码

Dim intScanCode As Integer = MapVirtualKey(VK_NUMLOCK, 0)

keybd_event(VK_NUMLOCK, intScanCode, KEYEVENTF_KEYDOWN, 0) ' 按下

keybd_event(VK_NUMLOCK, intScanCode, KEYEVENTF_KEYUP, 0) ' 放

想在win10平板上调用小键盘输入，在论坛上找到以上代码，这个触发代码是需要放在那里？比如是打开某窗口，就放在窗口的事件中吗？
