在VB中新建一个工程，放一个文本框与ListView，输入如下代码：
Option Explicit

Private Type POINTAPI
  X As Long

End Type

Private Type RECT
  Left As Long
  Top As Long
  Right As Long
  Bottom As Long
End Type

Private Declare Function GetCursorPos Lib "user32" (lpPoint As POINTAPI) As Long
Private Declare Function ScreenToClient Lib "user32" (ByVal hWnd As Long, lpPoint As POINTAPI) As Long
Private Declare Function GetKeyState Lib "user32" (ByVal nVirtKey As KeyCodeConstants) As Integer

Private Declare Function SetParent Lib "user32" (ByVal hWndChild As Long, ByVal hWndNewParent As Long) As Long
Private Declare Function MapWindowPoints Lib "user32" (ByVal hwndFrom As Long, ByVal hwndTo As Long, lppt As Any, ByVal cPoints As Long) As Long

        ByVal hWnd As Long, _
        ByVal wMsg As Long, _
