Passing information between two mdi child forms

Hey,
I have a mdi parent form as form1 and two child forms as frmA and frmB. frmA has one textbox& one button andfrmB has one listbox with several values. When i click on open menu on form1, then a new instance of frmA is created and shown as fA. Now when i click on the button on fA, it creates the new instance of frmB as fB with form1 as mdiParent. What i want to achieve is when i double click any value in the listbox of fB then the selected value should appear in the textbox of fA. The problem i am facing is that i dont know how to refer fA from fB as both are the instances of their respective forms.

Please help with a small code if possible. Thanks in advance.

Change the constructor for frmB and let it take an argument of type frmA. Store the passed reference in a class field for later use. When frmA creates an instance of frmB, it should pass "this".
