 You mean a cast where casting one way gives one result and casting
 another way yields a different result???  Hmm...  I can't think of
 any, but I can think of cases where it could be used, but isn't,
 within windows.
 There are some functions that have a prototype along the lines
 of:
 foo (int Action, long MoreInformation);
 Depending on Action, MoreInformation could be an integer value, or
 it could be a pointer to one or more types of structures.  So then,
 if MoreInformation was the address of a character string, you would
 have to cast the address to a long just to meet the syntax
 requirements of the proc call.
