Can anybody help me with this ->

I have one Parent and few Child (two of which are mentioned here) forms:

1.MDI Parent (Master.vb)
2.MDI child (Customer.vb) &
3.MDI child (Orders.vb).

On MDI Parent i have a panel (just below the menubar) which has the following buttons:

1. New
2. Edit
3. Save
4. Delete
5. Undo
6. Redo
7. First
8. Previous
9. Next
10. Last
11. Search
12. Print
13. Close

Now my problem is how do i determine the active MDIChild form and control it with the buttons located at Master.vb panel ? (Any help with codes would be great!)
