VB编程：利用控件数组设置控件状态-38

程序代码：

Private Sub Form_Load()

   For i = 0 To Label1.Count - 1

       Label1(i).Caption = "移动鼠标"

   Next i

End Sub

Private Sub Label1_MouseMove(Index As Integer, Button As Integer, Shift As Integer, X As Single, Y As Single)

   Dim mouseover As Boolean

   mouseover = (0 <= X) And (X <= Label1(Index).Width)

   If mouseover Then

       For i = 0 To Label1.Count - 1

           Label1(i).ForeColor = &H0&

       Next i

       Label1(Index).ForeColor = &HFF&

   End If

End Sub

学习总结：

   1、Count 返回 Long（长整数），包含集合中的对象数目。
