Thread Factory™ v4

Intoduction

Thread Factory™ is a DLL component library for easily creating robust Multi-Threaded Visual Basic 6 and VBA (Excel and Access) applications and components. Thread Factory empowers Visual Basic programmers with the ability to create COM objects that run on separate threads. Thread Factory's comprehensive framework includes an asynchronous calling architecture that parallels COM+ with Begin_ and Finish_ methods and built in asynchronous error handling. All this functionality is contained in a single 276K Runtime DLL with no MFC or COM+ dependancies.

Among Thread Factory's most noted features are its stability, performance and ease of use. Thread Factory adheres to all threading rules dictated by COM and eliminates any need to circumvent them. Licensed Developer's of Thread Factory may distribute their compiled applications Royalty Free.
