Size an mdi form with ismdicontainer property true and child form regardless of screen resolution

Hello Experts,
I have to size an mdi form (800*600 pixel) with ismdicontainer property true and child form regardless of screen resolution, so that the child form are contained in the mdi form without the scroll bars in the mdi form.
If I change resolution or the format of charater from 96 dpi to 120 dpi the scroll bar appear in the mdi form,
how can I resize the child form so that the the scroll bar do not appear also if I change screen resolution?

Another question: how can I set the backcolor of the mdi form, it is also dark grey also if I set a different color, from example green?

Thanks at all for help

Hi aldog1;

Let me take the easy question first. In order to change the BackColor of the MDI container you need to get a reference to the control that Microsoft places there and that is not available at design time. To change the BackColor of the MDI container see sample code below.

Fernando
    Private Sub Form1_Load(ByVal sender As System.Object, _
        ByVal e As System.EventArgs) Handles MyBase.Load
 
        For Each ctl As Control In Me.Controls
            If ctl.GetType Is GetType(MdiClient) Then
                Dim mdi As MdiClient = CType(ctl, MdiClient)
                mdi.BackColor = Color.Green
            End If
        Next
 
    End Sub

As far as the first part of the question you can use the Form.ReSize event to resize the child mdi's on the form by using the Form.ClientSize to get the available space on the form.
