Question

我在我的项目中制作了15个表格，之后我通过赠送属性isMDIparent true来制作家庭MDI。现在我想将所有形式作为家庭形式的子形式但是我没有办法做。所以请建议我将代码分配给所有表单以制作parentMDI主表单的子表单。

Answer 1

您需要将子表单的MdiParent Property设置为您的MdiContainer。此示例假定两个表单一个名为Form1，另一个名为Form2。所有属性都是以编程方式设置的。

Public Class Form1

    Public Sub New()

        InitializeComponent()
        Me.IsMdiContainer = True
        Dim frm2 As Form2 = New Form2
        frm2.Owner = Me
        frm2.MdiParent = Me
        frm2.Show()

    End Sub
End Class

Answer 2

以下是答案，直接来自微软：

Protected Sub MDIChildNew_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MenuItem2.Click
   Dim NewMDIChild As New Form2()
   'Set the Parent Form of the Child window.
   NewMDIChild.MdiParent = Me
   'Display the new form.
   NewMDIChild.Show()
End Sub

我认为Mr.Mark Hall错过了1处房产..，试试这个.......

Public Class Form1

Public Sub New()

    InitializeComponent()
    Me.IsMdiContainer = True
    Dim frm2 As Form2 = New Form2
    frm2.Owner = Me
    frm2.MdiParent = Me.MdiParent
    frm2.Show()

End Sub

End Class

Answer 4

实际上是这样的：

Private sub new()

Dim c as form1 = new form1
c.owner = Me
c.MdiParent = Me
c.show

End sub

InitializeComponent()正如它所说的那样，它初始化了一个组件。它不适用于Mdichild。

Answer 5

Private Sub HomeToolStripMenuItem_Click(sender As Object, e As EventArgs)
   Dim homechild As New login
   homechild.MdiParent = Me
   homechild.Dock = DockStyle.Fill
   homechild.Show()
End Sub
