How to transfer a variable from a Form to an other ?

[rom15becs]

Hi everyone,
I'm working on a project that uses 2 forms : one to select an object
and one other to display its attributes.
I mean that in the first one I select an object (from a ComboBox),
then I open a new form where I could see all the properties of that
object.

The problem is that I can't find a way to "transfer" my SelectedItem
from my selection Form to the other Form.

I tried to declare a private attribute with some accessors like that:
=====================================================
public partial class TheForm : Form
{
private MyObject _theObject;
public MyObject theObject
{
get
{
return this._theObject;
}
set
{
this._theObject = value;
}
}
private void TheForm_Load(object sender, EventArgs e)
{
============================================
But that generate accessibility errors on compilation.
Does anyone can help me Please ?

The accessibility error would probably be due to MyObject being
declared as an internal class. Either make it public, or make the
property internal too.

Define a property in the form TheForm. Before closing the form, set
the property's value to the control in question. When the form closes,
the property will be available to the form that opened TheForm.
