Actually changes were made, and still failure. Check out the strange
GetLastError message

Is this somehow impossible to do? Even though my DLL is in their process
via a Hook?

  lR = SendMessage(wOther,TVM_GETCOUNT,0,0);
   ....output routine shows correct count...
  hItem = (HTREEITEM)SendMessage(wOther, TVM_GETNEXTITEM, TVGN_ROOT,
(LPARAM)0);

  bStopIt = 0;
  while (hItem != NULL && bStopIt++ < 50)
  {
   memset(szBuffer, 0, sizeof(char)*256);
   memset(&item, 0, sizeof(TV_ITEM));
   item.hItem = hItem;
   item.mask = TVIF_TEXT | TVIF_CHILDREN| TVIF_HANDLE;
   item.pszText = szBuffer;
   item.cchTextMax = 256;

   lR = SendMessage(wOther, TVM_GETITEM, 0, (LPARAM)&item);
   dwTot = GetLastError();

       ....output routine shows a ZERO which is a failure...
       ....GetLastError returned a 183
ERROR_ALREADY_EXISTS???????????????????...

   hItem = (HTREEITEM)SendMessage(wOther, TVM_GETNEXTITEM, TVGN_NEXT,
(LPARAM)hItem);

  }
