主题：请教嵌入窗口及按钮控件加入红叉图片的问题

1、我想做一个主窗口，上面放一个panel,可以动态加入其它窗口，怎么实现？（网站好像有过案例，我没搜到）

2、动态加载的窗口，我想做成按钮集合展示在某区域，点击按钮可以切换窗口，点击按钮上的红叉则关闭按钮。

求思路或案例！

Dim PB As WinForm.Panel = e.Form.Controls("Panel2")

Dim Name As String = "工具栏"

Forms(Name).OPEN(-1000,-1500)

Forms(Name).BaseForm.TopLevel = False

Forms(Name).BaseForm.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None

Forms(Name).BaseForm.Dock = System.Windows.Forms.DockStyle.Fill

PB.BaseControl.Controls.Clear

PB.BaseControl.Controls.add(Forms(Name).BaseForm)
