I have an application that will display in a ListView a list of files, and 
their associated icons. As I scroll long lists of files up and down, the 
number of GDI and USER objects increases (according to task manager) until the 
GDI overflows at 10,000 objects. Why doesn't my code (or Windows) free up 
handles as it goes along? How can I reprogram this to avoid the overflow? Here 
is the code :-

     int jj,ci=ListView1->TopItem->Index,nr=ListView1->VisibleRowCount;
     int nof=ListView1->Items->Count; short icno=0; HICON asico;
     TListItem *li; char bf[MAXPATH+9];
     for (jj=0;jj<nr && ci+jj<nof;++jj)
     {
       li=ListView1->Items->Item[ci+jj];
       strcpy(bf,li->Caption.c_str());
       asico=ExtractAssociatedIcon(HInstance,bf,&icno); if (asico==NULL) continue;
 
DrawIconEx(Image1->Canvas->Handle,0,li->Position.y,asico,16,16,0,NULL,DI_NORMAL);
     }

TIA
