正　文:

   实现图片的放大缩小可以通过改变图片的宽度和高度来实现，下面举例说明。

操作步骤:
     打开ACCESS，新增一空白窗体，在窗体中添加一个图像控件，修改图片名称，设定图片来源，如下图：

    在窗体中添加两按钮，标题分别为“放大”，“缩小”，名称分别为”cmdBigger”,”cmdSmaller”，为两按钮的单击事件编写代码如下：

Private Sub cmdBigger_Click()

 Dim intWidth As Integer

Dim intHeight As Integer

With Image2

    intWidth = .Width

    intHeight = .Height

 .Width = intWidth * 4.05

    .Height = intHeight * 4.05

    .SizeMode = acOLESizeZoom

End With

' Allow Access time to Repaint Screen

' since we have Autorepeat set to TRUE for

' this Command Button

DoEvents

End Sub

Private Sub cmdSmaller_Click()
Dim intWidth As Integer

Dim intHeight As Integer

With Image2

    intWidth = .Width

    intHeight = .Height

    .Width = intWidth / 1.05

    .Height = intHeight / 1.05

    .SizeMode = acOLESizeZoom

End With

' Allow Access time to Repaint Screen

' since we have Autorepeat set to TRUE for

' this Command Button

DoEvents

End Sub

保存运行即可!
