Re: User v Custom Controls

Richard,
One problem that I'm seeing (I think - I'm no where near a managed C++
expert) is that you're not using managed strings.  Whenever you want a hard
coded string to be a managed string, you need to prefix it with an 'S'.  For
example:
State __gc* pState = new State(S"WA", S"Washington");

That creates a new States passing it the managed strings containing "WA" and
"Washington".

I quickly converted the VB code that you posted, and it worked fine.  If you
want me to, I'd be happy to e-mail you the code that I wrote (it may not be
the best, but it works).

Can someone help me translate this into C++? When I tried, the combobox
choked on the strings I gave it for the value and display members.

Public Structure State
    Private m_shortName, m_longName As String

    Public Sub New(ByVal longName As String, ByVal shortName As String)
        Me.m_shortName = shortName
        Me.m_longName = longName
    End Sub

    Public ReadOnly Property ShortName() As String
        Get
            Return m_shortName
        End Get
    End Property

    Public ReadOnly Property LongName() As String
        Get
            Return m_longName
        End Get
    End Property
End Structure

Private States() As State = {New State("Alabama", "AL"), ..., New
State("Wyoming", "WY")}

comboBoxState.DataSource=States
comboBoxState.DisplayMember="LongName"
