C#窗体编程不显示最小化、最大化、关闭按钮的方法
本文介绍在C#窗体编程时，如何设置不显示右上角的最小化最大化关闭按钮。可以通过this.ControlBox这个属性的值来控制。 在Windows的窗体编程中，基本上每一个窗体都是一个最小化、最大化和关闭按钮的。见惯了千篇一律，我们有时需要有一点新意，比如来把右上角的这最小化、最大化和关闭三个按钮去掉。 对于最大化和最小化按钮，在C#窗体开发时，各一个属性来启用或禁用这两个按钮。对于最大化来说，this.MaximizeBox=false即可禁用最大化按钮。而这里的this是指窗体对象本身。而this.MinimizeBox=false即可禁用最小化按钮。 上面说了怎么禁用最大化、最小化按钮，

Python作为自立门户的语言，除了学习它的基础编程之外，它还提供了窗体的学习，这样相对来说，它就完整了，如果大家学习过C#窗体实现或者Java，MFC等等吧，再学习它就会简单的多。当然大家也不用担心，即使没学过，...
