If you just want to display a user selected items as a message, then you
can read out the selected 'value' or 'text' one by one and concatenate
them. If you also need to manipulate these items, you may consider
dumpping the selected items into a slist first. A slist is very flexable
and is easy to handle. The following example is a list box with items 'a'
---'h'. Hope it gives you some ideas.
length nsel 8 text $8 sel_text $200;
*first get the total number of selected rows;
call notify('listbox1', '_GET_NSELECT_',nsel);
*loop over nsel to get strings and put them into a slist;
do i = 1 to nsel;
call notify('listbox1', '_SELECTED_',i,rowid);
call notify('listbox1', '_GET_TEXT_',rowid,text);
sel_text =sel_text ||' '|| text;
*here is the result in message window;
