房租管理小软件（八）：菜单相关设计

直接从数据库中加载菜单

其中　programName 是你需要加载的模块。

TYPE 是打开的类别

１.菜单：表示是它是一个菜单项。

２.功能：表示需要调用一段代码（Close,CloseThis,Region）等体

３.窗口：以弹出窗品的方式打开。

４页面：以MDIChild的方式，放到主窗体中。

IFShowINMenu :表示是否在菜单中显示。

代码如下：

  1 public void loadMenu(T1_QX_MyPermission p, DevExpress.XtraBars.BarSubItem sbarSubItem)
  2         {
  3 
  4             #region 菜单

  8                        t.FID == p.AutoID
