he suite of eight data-aware components:

• TFIB_Database
• TFIB_Transaction
• TFIB_Dataset
• TFIB_UpdateSQL
• TFIB_Query
• TFIB_StoredProc
• TFIB_Generator
• TFIB_CreateAlterDrop

for direct access of Firebird databases (Interbase also, but tested only on Interbase ver. 7.5). The components are based only on my own, not seldom non-standard, ideas.

Of course, TAnimateImage can animate images of an image list too. If you have frames of an animation as Bitmap or Icon, this component offers the easiest way to animate them. For this purpose, TAnimateImage provides some properties to specify interval, segment, and direction of images for the animation.
