Hi  friends

I have a typical problem in mdi child form.

I am having Three forms( One is Mdi parent(MDiParent)  and the other two are  child forms (Child1, Child2) )
------------------------------------------------
MDIParent Loads First
--
 Private Sub MDIParent_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Dim i As New child2
        i.MdiParent = Me
        i.Show()
    End Sub
-----
 The form child2 having one button control
--------
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim i As New child1
        i.MdiParent = Me.ParentForm
        i.Show
    End Sub
--------------

The form child1 properties.
--------------------------------
FormBorderStyle = System.Windows.Forms.FormBorderStyle.None
ControlBox = false

 Private Sub Form1_Activated(ByVal sender As Object, ByVal e As System.EventArgs) Handles MyBase.Activated
        MsgBox("some text")
    End Sub

------------------------
while running..
After loading the MDIParent

when I click the Button1 on child2 , child1 loads. The messagebox displays. At the time look at the child form, Its Icon is Flying window and the control box are all appears

How fix the error...
Thank you .
Prakash

hi prakash, that is not an error, that is a normal behaviour of mdi chils forms. ControlBox property has no effect on them, they have sizable borders, a control-menu box, and minimize and maximize buttons, regardless of the settings of the FormBorderStyle, ControlBox, MinimizeBox, and MaximizeBox.

Try this....
 
Private Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim objForm As New child1
        objForm.ShowDialog()
    End Sub

just dont set it as mdi child, you can achieve that by using the Owner property instead:

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim i As New child1
        i.Owner= Me
        i.Show
    End Sub

Hi EBatista

Owned Forms !!! .Your method works. The Menu in the child form are not goto the MDIparent .

I want it in MDI Child forms.

My form loads very slow because of the images . At the time for a few seconds (2)  the titlebar for child form & windows logo displayed.

How to prevent this ?

What u want to achieve can be done using a Parent Form and 2 Child Forms. Parent Form in your case should not be a MDI form. Create a normal form as the parent. Then call the child form from the parent using

Dim objForm As New child1
  objForm.ShowDialog()
