需要的函数声明：
Option Explicit
Private Declare Function GetCaretBlinkTime Lib "user32" _
() As Long
Private Declare Function SetCaretBlinkTime Lib "user32" _
(ByVal wMSeconds As Long) As Long
Private Declare Function GetCaretPos Lib "user32" _
(lpPoint As POINTAPI) As Long
Private Declare Function SetCaretPos Lib "user32" _
(ByVal X As Long, ByVal Y As Long) As Long
Private Declare Function DestroyCaret Lib "user32" () _
As Long
Private Declare Function CreateCaret Lib "user32" _
(ByVal hwnd As Long, ByVal hBitmap As Long, _
ByVal nWidth As Long, ByVal nHeight As Long) _
As Long
Private Declare Function ShowCaret Lib "user32" (ByVal _
hwnd As Long) As Long
Private Type POINTAPI

End Type
