yEnc Decode

[BiT]

Hi, I'm working on a newsgroup program and stuck on how to
decode the yEnc encoded articles (body).

i've found this dll of yenc32 - yDecLib.dll
in https://sourceforge.net/projects/yenc32/
but when i try to add it to my project i get error message: please make sure
that the file is accessible, and that it is a valid assembly or COM
component.

dose any1 kow source code or dll file of function to decode yenc?

thanks
