Winform 窗体美化问题

Question

由于项目需求，要对窗体进行美化。不用第三方控件。
将窗体设置成无边框，目前的问题是：窗体在移动与左放大、右放大没有闪烁，但是左缩小与右缩小会闪烁，请教有没有什么好的解决的办法？

Answer 2

            //减少闪烁
            //SetStyle(ControlStyles.SupportsTransparentBackColor , true);
            //SetStyle(ControlStyles.AllPaintingInWmPaint , true);
            //SetStyle(ControlStyles.UserPaint , true);
            //双缓冲
            SetStyle(ControlStyles.DoubleBuffer, true);
            SetStyle(ControlStyles.ResizeRedraw, true);
            //this.Refresh();

Answer 3

两个方法：
1、使用双缓冲内存位图直接操作；
2、使用wpf做个界面给程序调用.

简单,易懂,无闪烁

Answer 5

把Program下面的 Application.EnableVisualStyles();注释了此方法是启动可视化效果。

Answer 6

缩放移动的时候，挂起逻辑布局试试,完成后恢复
SuspendLayout()
ResumeLayout()
