Dim root As TreeNode
With TreeView1
.Nodes.Clear()
.ShowLines = True
.ShowPlusMinus = True
.ShowRootLines = True
root = .Nodes.Add("仓库") '增加根节点
.SelectedNode = root'在此根节点下添加子节点
For i = 1 To 6
node(i - 1) = .SelectedNode.Nodes.Add(i.ToString"号仓库")
Next
.ExpandAll()
End With

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vb.net添加子过程的属性中找到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vb.net添加子过程的时候vb.net添加子过程:
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.Length1 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
