An ActiveX Control which replicates the functionality of the 16-bit AAPLAY.DLL which was provided by Autodesk Inc. The control is written in pure 32-bit Delphi, and uses a combination of Device Independent Bitmaps (DIBs) and multi-threading for optimal performance. As far as possible, the functionality of AAPLAY.DLL has been replicated in the new component. It is also available as a 32-bit component for Borland Delphi 2 and 3.
