vb.net中怎么设置背景图片全部填充在窗体里

建个图片框控件，它有个随控件大小改变，图片也改变的属性，设置为“是”然后用该控件的MOVE方法，来实现。在Form_Resize事件里编，不知道NET有这个事件没。

vb.net 怎么把很多个图片框 放在一个容器或者其他 里面., 可以 有横拉条和下拉条的呢?

Panel控件就是容器，在窗体上添加一个Panel1控件，将其拖放到合适的位置与大小，然后设置Panel1控件的:

AutoScroll 属性为True

Panel1.AutoScrollMinSize 属性

Panel1控件里，添加你的图片框（此时可以滚动Panel1控件里的滚动条）

OK了吧！

vb制作的屏保系统，由多张图片循环播放，如何在图片播放时加上一定的特效，比如百叶窗等等，就像PPT制作的

'这个拿去试一试,两个时钟,两个图片框,自己设定图片框2的大小,比如让它和窗体一样大

'查一查PaintPicture的用法,就明白了
