Cant unhide all child forms? vb.net

I have the flowing problem. I have a vb.net parent form with MDI children that contain sensitive information. I have made a pause button which should hide all child forms from sight, this is no problem, calling them back is. i have for testing purposes created a button which should do the reverse however all my child forms stay hidden can somebody assist?

Code to hide all child forms is as follows:

For Each frmApproval As Form In Me.MdiChildren
        frmApproval.Visible = False

    Next
    System_Paused.MdiParent = Me
    System_Paused.Show()

Now the form nammed System_Paused has a button on it which when clicked should revert the hidden child forms but its not working?

        For Each frmApproval As Form In Me.MdiChildren
        frmApproval.Visible= true
    Next
    Me.Close()

You're iterating over the wrong MdiChildren collection.

You hide the children of your main form, but then you try to set the visibility of the children of the System_Paused form.

You could solve this issue by using something like this:

For Each frmApproval As Form In Me.MdiParent.MdiChildren
    frmApproval.Visible = true
Next

since you already set your main form as MdiParent of the System_Paused form.
