VB 类似于"鼠标取词"的代码

Private Declare Function SendMessage Lib "user32" Alias "SendMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, lParam As Any) As Long
Private Declare Function WindowFromPoint Lib "user32" (ByVal x As Long, ByVal y As Long) As Long
Private Declare Function GetCursorPos Lib "user32" (lpPoint As POINTAPI) As Long
Private Const WM_GETTEXT = &HD
Private Const WM_SETTEXT = &HC
Private Type POINTAPI
x As Long
y As Long
End Type

Private Sub Timer1_Timer()
Dim Shu As POINTAPI
Dim Str As String * 300
GetCursorPos Shu
SendMessage WindowFromPoint(Shu.x, Shu.y), WM_GETTEXT, 299, ByVal Str
Me.Caption = Str
End Sub
