LstSetListChoices does'nt make a copy of the data you pass to it, so you
must write:
void* strs = MemPtrNew(stringcount*sizeof(char*));
for(i=0;i< stringcount)
{
strs[i] = MemPtrNew(stringsize); // adapt this code
MemMove(stringptr,strs[i],stringsize);
LstSetListChoices(list,strs,stringcount);
}
If you're changing the contents of a popup list you may also call
LstSetHeight to adjust the number of visible items.
