Set items of listbox from another form or class

[ziycon]

I'm looking to add items on a listbox on form A from class B which is called from form A. I just don't know how to say add them to the listbox on the active form A from the class B!?
It's in C#, can anyone help?

how about referencing the other class/form to a sub that does it, (for vb)

*this is a sample in VB, perhaps you could recode it into C#, im not real experienced in that particular area.

Public Class Form1


    Public Shared Sub additemtolistbox(ByVal itemtoadd As String)
        Form1.ListBox1.Items.Add(itemtoadd)
    End Sub

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        myotherclass.subfromotherclasstoadditems()
    End Sub
End Class

Public Class myotherclass

    Public Shared Sub subfromotherclasstoadditems()
        Form1.additemtolistbox("test")
    End Sub
End Class

Got it working like this, have an if statement working off a int that counted how many records where in the table and shows all the elements of the returned array that have values. Works perfect.

public string[] getList()
       {
           DBConnect();

           string[] list = new string[100];
           int i = 0;

           QueryString = "SELECT title FROM listdat ORDER BY title ASC";
           command.CommandText = QueryString;

           Reader = command.ExecuteReader();
           while (Reader.Read())
           {
               list[i] = Reader.GetValue(0).ToString();
               i++;
           }

           DBDisconnect();

           return list;
       }

Hmm, it really depends on the structure of your class... is your listbox going to display each instance of Class B? Or is Class B Implementing a List? Or is Class B an instance of a class that has a list containing the items you wish to populate your listbox with?
