How can i add treeview control to my project. I cannot find this in components.

Go to the design mode of form to which u want to add tree view
In common controls tab u will find the treeview control just drag and add to the form

i am working in vb6 there is no treeview control on toolbox. I cannote locate in Project/Components also. I tried looking for MSTreeview in Components but cannot find.

It will be under components/Microsoft Windows Common Controls 6.0 (SP6). You will need service pack 6 installed, or under Microsoft Windows Common Controls 5.0 (SP2).

No problem. Happy coding.:)
