VB编程：利用控件数组设置控件状态-38

运行效果：

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。
