Q1: vb自适应分辨率
没有什么难的啊，窗体按分辨率大小，自动设置下就行了啊。
在LOAD时，添加上：
Me.Move 0, 0, Screen.Width, Screen.Height
就自动屏幕大小了啊。

Q3: vb.net 怎样将窗体和所有控件根据电脑分辨率固定？
使用SplitContainer1控件不就行了，SplitContainer1控件的Fixedpanel属性设置为Panel1\x0d\x0aSplitContainer1的Panel2里面再放置一个SplitContainer2\x0d\x0aSplitContainer2控件的Fixedpanel属性设置为Panel2\x0d\x0a二个SplitContainer设置为水平折为器方向\x0d\x0a至于播放器控件就放在SplitContainer2控件Panel1里面\x0d\x0a播放器控件DOCK设置为FILL\x0d\x0a\x0d\x0a这样不管放大缩小界面，播放器控件总是自适应窗体大小而菜单按钮总是在最边缘
Q4: vb.net保存图片时如何调整其分辨率
保存前加一句 myImage2.SetResolution(300, 300) 你设置的bMape不是保存的主画布 所以无效，设置分辨率就是 SetResolution（X,Y）
