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
这是一个提示消息的窗体，他继承自基类窗体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
提示消息窗体支持有确定取消按钮及单取消按钮，更多操作按钮暂没有增加
开始
添加一个Form命名为FrmDialog ，继承FrmBase
私有的构造函数
1 private FrmDialog(
2 string strMessage,
3 string strTitle,
4 bool blnShowCancel = false,
5 bool blnShowClose = false,
6 bool blnisEnterClose = true)
7 {
8 InitializeComponent();
9 if (!string.IsNullOrWhiteSpace(strTitle))
10 lblTitle.Text = strTitle;
11 lblMsg.Text = strMessage;
12 if (blnShowCancel)
13 {
14 this.tableLayoutPanel1.ColumnStyles[1].Width = 1;
15 this.tableLayoutPanel1.ColumnStyles[2].Width = 50;
16 }
17 else
18 {
19 this.tableLayoutPanel1.ColumnStyles[1].Width = 0;
20 this.tableLayoutPanel1.ColumnStyles[2].Width = 0;
21 }
22 btnClose.Visible = blnShowClose;
23 blnEnterClose = blnisEnterClose;
24 }搭配一个静态的公共函数

用处：一般用在一个需要用户确定的提示上
效果：
调用示例
1 if (FrmDialog.ShowDialog(this, "是否再显示一个没有取消按钮的提示框？", "模式窗体测试", true) == System.Windows.Forms.DialogResult.OK)
2 {
3 FrmDialog.ShowDialog(this, "这是一个没有取消按钮的提示框", "模式窗体测试");
