Multi Form App in VB.NET

[woklet]

From my main form, in a combo box, I call a second form like this:

dim NewForm as form2
NewForm = new form2
NewForm.show

After the user completes their work in form2, I need to get back to form1. How can I do this? If I do this from form2...

dim OrigForm as form1
OrigForm = form1
form1.show

...it creates another instance of form1. I need to get back to my original form1. How can I go back and forth from one form to another without re-creating them each time?

Thanks in advance
Ben

dim NewForm as form2
NewForm = new form2
NewForm.show

If you do not close the first form (form1) while opening form2, the form should stay there. Form2 appears on top of form1. By closing form2 (Me.Close within form2 itself) form1 should appear. If you want to invoke form1 back to the top without closing form2 you can try Me.SendToBack() in form2.

This is a classic problem thet can be resolved using "The singleton pattern", this is, the need to have one (and only one) instance of an object within the system, and having a single point of access for other objects.
