You can add the following code:

//code for open form
Parties_Entry parties = new Parties_Entry();
parties.MdiParent = Main_Form.mainObj;
parties.Name = "parties";
if (this.ActiveMdiChild != null)
{
MessageBox.Show(this.ActiveMdiChild.Name);
if (this.ActiveMdiChild.Name != "parties")
parties.Show();
}
else
{
parties.Show();
}

You need to store the form reference (parties) someplace where the program can use it whenever it needs to.
