Hi Uniquegodwin,

I found something for you in MSDN, see this link:

http://msdn.microsoft.com/library/de...childforms.asp

And I think you'll find more about that aswell.

Hope it can help you in the good direction.

Hi,

Found more about MdiChildren.

In this example, you create two forms: Form1 and Form2. You set the IsMdiContainer property of Form1 to true and make it the MdiParent of Form2. Next you create a button, button1, on each form. When the button on the parent form is clicked, the event handler displays the child form. When the button on the child form is clicked, the event handler displays the Name property of its parent form. Use the following two code segments to overwrite button1 event handlers in both forms. You can use the property
Show and Hide on those Forms.


' The event handler on Form1.

VB Code:

Private Sub button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
    ' Create an instance of Form2.
    Dim f2 As New Form1()
    ' Make this form the parent of f2.
    f2.MdiParent = Me
    ' Display the form.
    f2.Show()
End Sub 'button1_Click

I think this is a better sulution for your problem.

A form's MdiChildren property is just an array of Form references, so to hide all MDI child forms it's as simple as:

VB Code:

For Each child As Form In Me.MdiChildren
    child.Hide()
Next child

Because any type of form can be an MDI child each element is typed to Form. This means that if you wanted to access members of the specific type of a child form you'd have to test the type and then cast it, just like you need to cast items from an ArrayList because they are all Object references.

Never thought this way...its simple :)
Thanks Jm :)
