Rakesh,

If you use the constants in foxpro.h it's a lot more readable:

nYn=messagebox("Add New", MB_YESNO + MB_DEFBUTTON2,"New")

if ( nyn = IDYES )
   * picked yes
else
   * picked no
endif

6 is not a valid option for the second parameter, I get just a single Ok button, not Yes/No buttons.

>nYn=messagebox("Add New",6,"New")
