However, checksums have other uses, such as in dialog box change-state maintenance, document change-state maintenance, and similar applications.This essay tells you a bit about how I use a checksum algorithm for this purpose, and includes a sample checksum class you can copy-and-paste into your application. Having too many complex variables around to hold old fonts, the next-oldest old font, the saved region, the saved bitmap, the saved ROP, the saved transform matrix, the saved pen, the saved brush, the previously-saved brush; the brush that was the brush before the previously-saved brush was saved..get the idea.Do the C Library functions and the Windows API functions return the same values? Check out this table (beware: this is a massive file!

Some are for experienced programmers poking into previously unknown areas of MFC. Some are simply my take on "best practice", style issues I feel strongly about, and which are not addressed adequately by the Microsoft documentation, and in some cases which have a folklore of incorrect methodology which is promulgated on the newsgroups. Note that these essays represent, in many cases, my opinion of the right way to do things. Well, the answer is simple: their opinion may not be right.
