单项选择题
要求当鼠标在图片框P1中移动时，立即在图片框中显示鼠标的位置坐标。下面能正确实现上述功能的事件过程是
A)Private Sub P1_MouseMove(Button As Integer，Shift As Integer，X As Single，Y As Single)
Print X，Y
End Sub
B)Private Sub P1_MouseDown(Button As Integer，Shift As Integer，X As Single，Y As Single)
Picture.Print X，Y
End Sub
C)Private Sub P1_MouseMove(Button As Integer，Shift As Integer，X As Single，Y As Single)
P1.Print X，Y
End Sub
D)Private Sub Form_MouseMove(Button As Integer，Shift As Integer，x As Single，Y As Single)
P1.Print X，Y
End Sub
答案
参考答案：C
解析： 鼠标在图片框中移动，对象应为图片框控件，而不是窗体，选项D)是错误的；鼠标移动触发的是MouseMove事件，选项B)是错误的；在图片框内显示坐标，Print的对象名为图片框，如果没有对象名，则默认输出到窗体上，所以正确的答案为C)。
