VB编程：利用控件数组设置控件状态

VB编程：利用控件数组设置控件状态

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。
