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
