Creating Customize tab control

Hi,

     Ii am creating a project which have two mode of operation 1.Auto 2.Manual.  I use MDI form to display selected mode window. I also create tree view (when i click on treenode perticular mode will display) now i want to create tab on top (below the toolstrip)(not a tabcontrol tool in our toolbox)so when i click on tab window it will display perticular window and it should have option to close(we can see it on our visual studio itself. we open different winows and can select or close which we want) so how it can be possible?
