Soykan,

You can use the Selected[] array of the listbox to preselect items in code. You have to set Multiselect = .t.

for i = 1 to this.ListCount step 2
   this.Selected[i] = .t.
endfor

you use the same loop to find out what items are selected.

for i = 1 to this.ListCount step 2
   if ( this.Selected[i] )
      * the item is selected
   endif
endfor
