UI to enter values into a structure

For a nested structure such as:

Dim userVariable as one

structure one
dim a as string
dim b() as two
end structure

structure two
dim c as string
dim d as string
end structure

before I do the monkey work of creating a VB.Net UI for an end user to
fill out values for userVariable, I was wondering if there's a generic
code sample that will take in a structure and provide a dynamic form to
fill out its properties. Although the nested structure I'm working
with is more complex than this example, all data types are either
strings or integers.

Any insight is greatly appreciated.

Thanks,

Jim

Hullo Jimbo,
Your best bet is going to lie with the Reflection classes.

Check out the System.Type class... something along the lines of:

Public Structure Foo
    Private sSomeString As String

    Public Property SomeString As String
        Get
            Return sSomeString
        End Get
        Set (byval tValue as String)
            sSomeString = tValue
        End Set
    End Property
End Structure

Public Sub MakeForm()
    Dim tInfo as PropertyInfo = Nothing

    For Each tInfo in GetType(Foo)
        ' Do some crap.. make the form field.. etc.
    Next

end Sub

Thanks for your help. This seems like a good idea for a GotDotNet
project!
