Change the location of Mdi Child forms...

I am  developing a windows app using c#. I have mdi parent form in which form border style is set to none (none for all forms).

In mdi parent form on top there is a label with size 761,57 at location 0,1. and below that there is menustrip with size 76,21 (width may increase depending upon the menus) at location 1,58.

 Now I want to want that when child form is opened it should appear below menustrip. how can it be done with code ??

 

Thanks in Advance ...!!!
