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.
