将子窗体带到面板控件的MDI前面

Question

我需要在MDI窗体上应用DoubleClick事件，为此，我在MDI窗体上放置了Panel1控件并将其停靠栏填充为填充。
但是，当我打电话给任何子窗体，它在Panel1后面运行。
我想这个代码MDI形式的许多事件和子窗体：

childForm.TopMost = true 
childForm.BringToFront = true  

，但它不工作！

您需要添加对PowerPack DLL的引用，并使用Shape来代替。下面是一个例子

Imports Microsoft.VisualBasic.PowerPacks 

Public Class MDIParent1 
    Dim C As New ShapeContainer 
    Dim WithEvents R As New RectangleShape 

    Private Sub MDIParent1_Load(sender As Object, e As EventArgs) Handles Me.Load 

     C.Parent = Me 
     R.Parent = C 
     R.Top = 0 
     R.Left = 0 
     Me.Controls.Add(C) 

    End Sub 

    Private Sub MDIParent1_Resize(sender As Object, e As EventArgs) Handles Me.Resize 

     R.Height = Me.Height 
     R.Width = Me.Width 

    End Sub 

    Private Sub R_DoubleClick(sender As Object, e As EventArgs) Handles R.DoubleClick 

     MessageBox.Show("Shape Double-click") 

    End Sub 
... 
End Class
