I have a structure that contains variables (i.e. Name, Address, Cit, State, Zip, telephone).

Is there a way to clear the structure with 1 command, like structure.clear?

or must I clear each variable?
 
Code:
    Structure Customer
        Dim Name As String
        Dim Address As String

        Sub Clear()
            Name = ""
            Address = ""
        End Sub
    End Structure

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

        Dim c As New Customer
        c.Name = "John Doe"
        c.Address = "123 Main Street"
        MessageBox.Show("Name:  " & c.Name & "  Address:  " & c.Address)
        c.Clear()
        MessageBox.Show("Name:  " & c.Name & "  Address:  " & c.Address)

End Sub
 
Structures may also contain methods. You would have to clear each field individually, but only in the structure's Clear method:
Code:
Public Structure YourStruct

    Public Name As String
    ' ...
    Public Telephone As String

    Public Sub Clear()
        Name = String.Empty
        ' ...
        Telephone = String.Empty
    End Sub

End Structure
 
You could also just destroy your instance of the object, and then re-instatiate it, giving the same effect.
 
Structures gave birth to Classes in object oriented programming. You can write methods (functions, subs) to add them functionallity

Your program may be using structures currently but
the preferred way is to use classes.

Says who? You can't really make sweeping generalizations like that with the little information provided about the project.
