Multiform application without MDI using Panels 1

[davisg]

I want to write a multiform application but I don't want to use MDI. I have seen this done in other languages, i.e. Delphi. Is there a way you can open a form from within a form and view it in a control such as a panel?

e.g.

Dim frm as new myform()
frm.parent = Me.Panel1
frm.Show()

The above gives me an exception of: Cannot add a top level control to a control.

Any takers on this one? I'm sure it can be done !

Set the 'child' form's TopLevel property to False and it will work:

Dim f as New Form2

f.TopLevel = False

Panel1.Controls.Add(f)

f.Show

SHelton,

Many thanks, that worked a treat.

How do you limit to only one instance of a particular form?

Something along the lines of the following should work:

For Each ct As Control In Panel1.Controls

    If TypeOf ct Is Form2 Then Exit Sub

Next

'No Form2 in panel, create it...
