Getting the Index of a MDI Child Form [Not Solved]

[CrisIsRatedX]

I am writing a MDI program and I need to know how I can get the index of a MDI Child Form. Is there any possible way to do this in VB.NET 2005?

Dim save As New frmSave
            save.txtExt.Text = ".txt"
            save.MdiParent = MdiParent
            save.Show()

NOTE: The form that this code is coming from is not the MDI Container.

Thank you for your help!

MdiParent is the form whose IsMdiContainer property is True. It has an MdiChildren property, which is a Form array. You can use the Array.IndexOf method to find the index of any form in that array.

I tried doing that with this code.

With frmMain
                Dim frmArr() As Form = .MdiChildren
                Dim int As Integer
                int = frmArr.IndexOf(frmArr, Me)
End With

It has a green line under frmArr.IndexOf Anyway to get rid of that or did I write the code in the wrong way?

Did you read the documentation for the Array.IndexOf method? If you try something and it doesn't work, reading the instructions should be the first thing you do.
