如何给VB.NET窗体添加子窗体？

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

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 Sub

常见的窗体类型有哪几种?它们的主要不同点是什么?

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。
