The code for this article was written for version 1.0 of the Active Template Library (ATL). The current version of the code (in SieveATL) was built with Visual C++ 6.0 and the ATL provided with that compiler. It may be slightly different than the code shown in the article. The directory SieveMFC contains an MFC version of a component equivalent to the ATL version discussed in the article. It was built with version 5 of the C++ compiler and the MFC version provided with it. The code discussed in the article was later adapted for Hardcore Visual Basic, Second Edition. Comparable Visual Basic versions are discussed in Chapter 10 of the book. Bruce McKinney
