Many applications use connection/object pool. A program may require a IMAP connection pool and LDAP connection pool. One could easily implement a IMAP connection pool, then take the existing code and implement a LDAP connection pool. The program grows, and now there is a need for a pool of threads. So just take the IMAP connection pool and convert that to a pool of threads (Copy, paste, find, replace????). Need to make some changes to the pool implementation? Not a very easy task, since the code has been duplicated in many places. Re-inventing source code is not an intelligent approach in an object oriented environment which encourages re-usability. It seems to make more sense to implement a pool that can contain any arbitrary type rather than duplicating code. How does one do that? The answer is to use type parameterization, more commonly referred to as templates.

This PNG Delphi version 1.56 documentation (this version is a major rewrite intended to replace the previous version, 1.2). Improvements in this new version includes: This new version allows the programmer to not use Delphi heavy units which will greatly reduce the size of the final executable. Read more about this feature here. Most, if not all, Portable Network Graphics features as CRC checking are now fully performed. Error on broken images are now better handled using new exception classes. The images may be saved using interlaced mode also. Transparency information won t be discarted after the image is loaded any more. Most of the images are decoded much faster now. The images will be better encoded using fresh new algorithms. IMPORTANT! Now transparency information is used to display images.

This build is for developing a "binary-to-BCD" converter for use in // displaying numerals in base-10 so that people can read and interpret the // numbers more readily than they could if the numbers were displayed in // binary or hexadecimal format. Also, a "BCD-to-binary" converter is // tested in this build.
