Passing Vb equivilent of "structs" between forms

Hi,

I'm working with VB 2005.net and have managed to get my head around passing
values between forms by creating properties of the relevant form classes.

However, say that I have a number of values which I wish to exchange (for
example, an employee record, name, position, etc). At the minute I'm using a
seperate property to for each "field".

I was wondering, is there a way to collate all the fields into one "object"
and use that as a property? I'm reminded of a "struct" from my C days and
was wondering if VB provided anything similar?

Any and all advice, tips, links and abuse are gratefully received.

Thanks

Chris,

Martin,

Thank you and apologies for my laziness / myopia when it comes to the help
files.

Thanks

You're forgiven, the helpfiles of VS2005 are totally useless ;-)

Properties of what? Each Form? Or a Class, each instance of which
represents an Employee?

You could go with a Structure (the direct equivalent of struct) but,
personally, I'd jump straight in with a Class. Maybe something like this
(only with [lots] more Properties):

Class Employee
    ' ? Inherits BaseClassForAnyPerson

    Private m_EmpNumber As String = Nothing

    Public ReadOnly Property EmpNumber() As String
        . . .
    End Property

    Public Sub LoadFrom( ByVal source As ... )
        m_EmpNumber = source.Something
        . . .
    End Sub

    Public Sub SaveTo( ByVal source As ... )
        . . .
    End Sub

    Public Sub New( ByVal source As ... )
        Me.LoadFrom( source )
    End Sub

End Class

HTH,
