I have one form which is MDIParent (formA), now i call a MDIchild (formB) from formA.

code:
Dim f as new formB
f.MDIParent=Me
f.show()

On formB, i have a button to call another normal form (formC).
My question is, how to make formC as child for formA?

thank you for your replies... i really appreciate it....
