DLMSDirector code. read value by logical name

Hi,
I try to modify code DLMSDirector in c#.

In MainForm.cs inside DeviceGb (groupbox) i have created a label (label3).
how can I associate this label with a registry value?

example i have this value in object type "register":
Logical Name "1.1.2.8.0.255"
Value=1234567,6

is there a simple function, example value=ReadValue("1.1.2.8.0.255") in some class?
And how can I use it in MainForm?

I replied the "read" Command of the menu and called it test. Can I change this function in any way for read my value?

Thx!!

private void testToolStripMenuItem_Click(object sender, EventArgs e)
{
if (tabControl1.SelectedIndex == 0)
{
//Set focus to the tree or Read count do not updated.
this.ObjectTree.Focus();
if (this.ObjectTree.SelectedNode != null)
{
TransactionWork = new GXAsyncWork(this, OnAsyncStateChange, Read, OnError, null, new object[] { this.ObjectTree.SelectedNode.Tag, SelectedView });
TransactionWork.Start();
}

}

}
