00Component lists [D1 D2 D3 D4 D5 D6 ]
Components with (sw) after their name are shareware.
****=Excellent site
*** = good
** = fair, but still worth a look
* = good if nothing else works out

If you are looking for a component, first try the Jedi project, it has over 300 visual components. http://projectjedi.sourceforge.net. Then try RXLib (docs are sparse).

TMD5 [D2 D3 D4 ]
TMD5 produces cryptographically secure hashes which comply with the RFC1321 standard. Hashes can be used to securely store passwords, sign files or text, or produce checksums. Changing even one bit of the input changes the hash entirely in a way that can not be faked. Source: Purchase/Registration [Report a dead link]

Qlist [D3 D4 D5 D6 ] SOURCE
The Delphi TList and TStringList classes are an essential part of the Delphi programmer's toolkit but they have a couple of limitations. One is their severely restricted capacity in Delphi 1. Another stems from their tendency to fragment the heap, eventually leading to poor performance.

The TQList and TQStringList classes hold up to a quarter of a billion items (memory permitting!) and do so with much reduced memory fragmentation. Generally operations that cause the lists to grow are faster with QLists. The trade off is with the access time. TQList is about 4x slower than TList and TQStringList about 2X slower than TStringLIst. Once, however, the extra overhead of actually manipulating the data you have stored is included the difference is less signficant. [Report a dead link]

Tlist [D6 ]
A list of pointers, comes with Delphi 6.

TSparseList [D5 D6 ]
A simple descendant of TList that reduces memory fragmentation. When items are deleted from the list, the slots are kept open so newly added items can be added into those slots. This avoids having to move memory whenever an item is deleted, and allows the list to reclaim memory used by deleted items. [Report a dead link]
