Forms collection
In VB6, there was a forms collection you could iterate to get a list of forms that were open in your application at runtime. I want to do something similar in vb.net. I have an MDI application. Several of the forms can have multiple instances, but one in particular, I only want the user to be able to only create one instance. If the form has already been created, but has been minimized or is in the background of another child form, I want to restore and/or bring it to the front.
In VB6, I would do something like:
bFormFound = False
For Each frm In Forms
If frm.Name = "myForm" Then
If frm.WindowState = vbMinimized Then frm.WindowState = vbNormal
frm.SetFocus
bFormFound = True
Exit For
End If
Next
If Not bFormFound Then
...create new instance here.
End If
How would I replicate this code in VB.Net 2005?

Bob,
I am sorry, I did not see your answer. Notifications go to my personal email address and I usually shut down Outlook in the morning so I can access my personal email from work. I forgot to this morning and just so happened to get onto web mail before Outlook had grabbed Jamie's solution, so when I clicked on the link, I jsut saw his solution. In all fairness, had I noticed your post, I would have split the points. Also, in fairness, I probably still would have used his solution. Although all I have is the MDIParent and child forms, it does provide at least one less form in the collection that is being iterated than your solution does.
I'll catch you next time.

Dim frm As New myForm()
