两种方式实现：PPT中实现图片的拖动功能.doc

1、【PPT中也能实现图片的拖动功能】本文档内包括两种方法来实现现对PPT中如何实现：当播放PPT时，能够随意拖动图片到指定位置（补充：通过插入制作好的FLASH也可以实现这样的效果，后续有时间了会接着发布的，敬请期待）。、一、通过宏实现PPT中图片的拖动功能此处建议将宏的安全级别设置为低。1打开你要设置图片拖动功能的PPT。2点击菜单：“工具宏宏”，出现对话窗口。3填写对话窗口中的“宏名”，宏名可以随意命名，比如：wantmove，再点“创建”，就进入代码模式。4删去所看到的所有的代码，然后把下面的代码全拷贝进去。Option ExplicitDeclare Function GetKeySta

9、，放开后，图片就随你鼠标移动，如果你再单击鼠标，图片就停在你单击的地方。二、通过VBA编实现PPT中图片的拖动功能此处建议将宏的安全级别设置为低。1在演示文稿插入图像控件（视图工具栏控件工具箱），打开属性窗口，将picture设成你想拖动的图片（图片大小要根据实际情况进行调整），遗憾的是Image控件不支持透明。2双击图像控件，打开的VBA编辑窗口（注意双击后先删除所有代码），复制下面的代码：Dim X1, Y1 As IntegerDim Down As BooleanPrivate Sub Image1_MouseDown(ByVal Button As Integer, ByVal Sh
