前提
入行已经7,8年了，一直想做一套漂亮点的自定义控件，于是就有了本系列文章。

准备工作
这个窗体继承子基类窗体FrmBase，如果你对FrmBase还不了解，请移步 （十七）c#Winform自定义控件-基类窗体 查看
气泡需要支持多个位置显示，也就是说四面八方都可以显示，并且支持样式，自定义大小，另外具有内置的4中模式（成功，错误，警告，正常）
开始
定义一些枚举
1 public enum TipsSizeMode
2 {
3 Small,
4 Medium,
5 Large,
6 None
7 }
8 public enum TipsState
9 {
10 Default = -1,
11 Success = -6566849,
12 Info = -12477983,
13 Warning = -357816,
14 Error = -1097849
15 }添加Form，命名FrmTips，继承自FrmBase

用处：向用户提示一些信息，但是这些信息又不是非常重要，不需要用户确定的时候可以用到这个东西
效果：
调用示例
1 FrmTips.ShowTipsError(this, "Error提示信息");
2 FrmTips.ShowTipsInfo(this, "Info提示信息");
3 FrmTips.ShowTipsSuccess(this, "Success提示信息");
4 FrmTips.ShowTipsWarning(this, "Warning提示信息");
