Add*** methods add items to the end of document, so its itemno =

rve->ItemCount-1 (immediately after call of Add*** methods).

But actually, tags usually required for some specific items.

For example, tags of items in the position of caret is returned by

GetCurrentTag.

Tag of clicked hypertext item:

void __fastcall TfrmMain::rveJump(TObject *Sender, int id)

{

  int ItemNo;

  TCustomRVFormattedData* RVData;

  rve->GetJumpPointLocation(id, RVData, ItemNo);

  AnsiString s = (char*)RVData->GetItemTag(ItemNo);

  Application->MessageBox(s.c_str(), "Link", MB_OK | MB_ICONINFORMATION);

}
