VB.NET Form Modal vs. Non-modal vs. Owner

I have Form1 and Form2 which should be accessible to the user independently.  A button on Form1 will open Form1A (should be modal to Form1 only) and open Form2 (accessible while Form1A is open):
        Form2.Show() 'Should be independent from Form1 and Form2
        Using frm As New Form1A
            frm.Owner = Me
            frm.ShowDialog()
            'When Form1A closed, do something with user entered data
        End Using 

Open in new window


I have tried using a mixture of owner and show vs. showdialog, but if the Form1A is modal, it also blocks access to Form2.  I need for the user to be able access both Form1A and Form2 at the same time.   When open, Form1A should of course prevent access to Form1.  I realize that I could probable add code to Form1A in the FormClosing event, but I also want the code to be cleaner, and Form1A could be opened from various other forms as well.  Any thoughts on how to accomplish this?

A form is modal at the application level, so there is not way to do what you want from inside the same application.

You could however hide or disable Form1 while Form1A is on the screen, something like the following:

Me.Hide
Form1A.Show
Form2.Show
Me.Show

or

Me.Enabled=False
Form1A.Show
Form2.Show
Me.Enabled=True

The only problem with Enabled is that Form1A will flash a few time if the user clicks on Form1 while it is disabled. There might be a way to prevent that, but I do not have time to look into that.

I was hoping for a way out, but I will have to accept that modal is at the application level.  JamesBurger's suggestion is a reasonable start.
