[RESOLVED] Get control collection from mdi active child form

[tassa]

Yes, sorry, I now see I have explained myself poorly.

I have a MDI form, which adds a user control (which has three textboxes) in each MDIChildForm. When adding the control I create a new instance like so:

Private Sub ShowNewForm(ByVal sender As Object, ByVal e As EventArgs) Handles NewToolStripMenuItem.Click, NewToolStripButton.Click, NewWindowToolStripMenuItem.Click
        ' Create a new instance of the child form.
        Dim ChildForm As New System.Windows.Forms.Form
        ' Make it a child of this MDI form before showing it.
        ChildForm.MdiParent = Me
 
        m_ChildFormNumber += 1
        ChildForm.Text = "Untitled " & m_ChildFormNumber
 
        ChildForm.Controls.Add(New UserControl)
        ChildForm.Show()
    End Sub

I want to get the control collection to harvest the data inputed by the user in each textbox. I had created read only properties in the user control so it would be easier, but, for some reason, when reading it comes back empty.
