Hi

Why is my mdichild form not starting in the "centerparent" position? I'm
using the following:

Public Class frmCAD
Private Sub MakeNewCallToolStripMenuItem_Click(ByVal sender As
System.Object, ByVal e As System.EventArgs) Handles
MakeNewCallToolStripMenuItem.Click
Dim frmNew As New frmMakeNewCall()
frmNew.MdiParent = Me
frmNew.StartPosition = FormStartPosition.CenterParent
frmNew.Show()
End Sub
End Class

Thanks

MDI children ignore the StartPosition property, as well as any other
attempt to set their position prior to .Show.

Put this in the Load event of every MDI child form you want centered:

CenterInParent(Me)

And this in a module:

Sub CenterInParent(ByRef frm As Object)
frm.Left = Higher((frm.Parent.ClientSize.Width - frm.Width) / 2, 0)
frm.Top = Higher((frm.Parent.ClientSize.Height - frm.Height) / 2,
0)
End Sub

Function Higher(ByRef x, ByRef y)
Higher = IIf(x > y, x, y)
End Function
 
Hi

thanks for that.......

suppose I shouldn't ask, but if the MDI children ignore the StartPosition
property why provide a "centreparent" option for the startposition ????.
Answers on a postcard to Microsoft.com please

Thanks again

Can I just ask in addition to this, I would like to remember the previous
location of the window on the MDI parent for the child form. I can do this.
However, when displaying the window opens at its original location then
moves. Is there anyway to do this (perhaps using API calls or something) that
can move a window on it's initial display without flickering it?

Thanks
Mike
