现有一个image控件，当鼠标移到该控件时，变换另一图像，鼠标移开，又变回原图像，求代码
第一个回答太简单，第二个回答经测试，移进去可以，移出去后不能还原原图像

Private Sub image1_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)
'鼠标在image上移动
image1.picture = loadpicture("c:\2.bmp")
End Sub
Private Sub form_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)
’鼠标离开image,在窗体上移动
image1.picture = loadpicture("c:\1.bmp")
End Sub

Private Declare Function SetCapture Lib "user32" (ByVal hWnd As Long) As Long
Private Declare Function ReleaseCapture Lib "user32" () As Long

4) 在Command1的MouseMove事件中编写以下代码：
Private Sub image1_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)
Dim MouseEnter As Boolean '鼠标进入的标志位

MouseEnter = (0 <= X) And (X <= image1.Width) And (0 <= Y) And (Y <=
Command1.Height) '计算鼠标的移动是否在image1里面
If MouseEnter Then '鼠标已经进入
set image1.picture = loadpicture(&q
