I have not gone through your source code but one of the obvious error is
your strings are stored in a local variable "items". Which gets destroyed
after you return from MainFormInit. Make it global, better still use a two
dimentional pointer along with a variable for stroing the number of elements
in "items" and free it when you don't need it.
