直接添加一个MID父窗体或在已有窗体的属性中找到IsMDIContainer属性，然后设置为True，然后创建第二个窗体 ，需要加载子窗体的时候：
Dim NewMDIChild As New Form2
NewMDIChild.MdiParent = Me
NewMDIChild.Show()
Public Shared Sub CheckMDIChildForm(ByVal MDIForm As Windows.Forms.Form, ByVal MDIChildForm As Windows.Forms.Form, ByVal MDIChildFormName As String)
If MDIForm.MdiChildren.Length 1 Then
'如果没有任何一个MDI子窗体，则创该MDI子窗体的窗体实例
Dim MDIChildFrm As Windows.Forms.Form = MDIChildForm ' 定义MDI子窗体
MDIChildFrm.MdiParent = MDIForm '指定父窗体
MDIChildFrm.Show() '打开窗体
Exit Sub
Else
Dim x As Integer
Dim frmyn As Boolean
For x = 0 To (MDIForm.MdiChildren.Length) - 1
Dim tempChild As Windows.Forms.Form = CType(MDIForm.MdiChildren(x), Windows.Forms.Form)
If tempChild.Name = MDIChildFormName Then
'检测到有该MDI子窗体，设为激活 并退出循环
frmyn = True
tempChild.BringToFront()
Exit For
Else
frmyn = False
End If
Next
If Not frmyn Then
'在打开的窗体中没检测到则新建
Dim MDIChildFrm As Windows.Forms.Form = MDIChildForm ' 定义MDI子窗体
MDIChildFrm.MdiParent = MDIForm '指定父窗体
MDIChildFrm.Show() '打开窗体
End If
End If
End Sub
常见类型：平开窗、推拉窗、倒窗、百叶窗、天窗。
不同点：
1、开启方式不同。
平开窗窗扇通过铰链与窗框结合，窗扇可以旋转开启；推拉窗则采用装有滑轮的窗扇在窗框上的轨道滑行；倒窗通过旋转窗子的把手，带动窗子内部五金机构开启；百叶窗无法很好地密闭，仅通过百叶角度开关；天窗一般不可开启。
2、密闭性不同。
平开窗关闭时气密性好；推拉窗最多只有50%的窗扇可以打开，关闭时气密性差；倒窗多锁点密封，可以使窗子的密封性大大增强；百叶窗密闭性较差；天窗一般不可开启，密闭性较好。
3、适用条件不同。
平开窗一般用于厨房、卫房间等的通风换气；推拉窗用于空间狭窄的位置；倒窗不用破坏原有窗体，升级方便快捷；百叶窗必须和普通的窗或玻璃幕墙结合在一起使用；天窗常用于采光。
扩展资料
窗户的组成：
现代的窗户的窗由窗框、玻璃和活动构件（铰链、执手、滑轮等）三部分组成。窗框负责支撑窗体的主结构，可以是木材、金属、陶瓷或塑料材料，透明部分依附在窗框上，可以是纸、布、丝绸或玻璃材料。
活动构件主要以金属材料为主，在人手触及的地方也可能包裹以塑料等绝热材料。材质可分成三大类—塑钢、铝合金、木质。三者各有所长。
