>Zlib.dll is freeware and so many devloper in world using it.

Hi Tao,
I too am having trouble with the Zlib.dll giving me the error
"cannot find entry point COMPRESS in the dll". I placed the DLL
in the Windows System and Syetem32 but it did not work. I am using
your code:

FUNCTION compressit( infile )
DECLARE INTEGER COMPRESS IN zlib-1.DLL AS zlibCompress ;
STRING @ DEST, INTEGER @ destLen, ;
STRING src, INTEGER srcLen

I am running Windows 2000.

Got any ideas what might be wrong?
Thanks,
Terry
