Hi
This is the solution for your problem. The problem with your code is
LstGetSelectionText(lptr,sel); cannot work for dynamic textitems in a list.
The list control doesn't know the item u selected. because you are not
storing the item sin list statically. it will work only for static list
items (which will be created in constructor)
case popSelectEvent:
switch ( event->data.lstSelect.selection )
{
case YOURLIST:
listP = FrmGetObjectPtr(frm, FrmGetObjectIndex(frm,YOURLIST));
listsel = LstGetSelection(listP);
GetProjectRec(listsel,&prec) // get the selectd item from
database
pname=MemPtrNew(StrLen(prec.Name)+1);
StrCopy(pname,prec.Name);
handled = true;
break;
}
Thank U
Narasimha Prasad B.
