VC++ MFC Challenge TREE CONTROL WITH Checkboxes

Dear All,

I am developing an application in which I require a "tree control with checkboxes".
The structure of tree control is as:

Main_Root
Child_1
Child_2
Child_3
Child_4
Child_5
Child_6

ie. simple tree having one main root and having many child items.

I have two problems related to it.

1)
All child items should be checked to TRUE whenever we click 'root' checkbox and vice-versa. How to proceed for it ???????

I mean to say that which event should I capture for this.( ie. TVN_SELCHANGING )
Please send some code for this if possible.

2)
Is there any way to disable a particular check-box in tree control.

Thanks in advance.
