I am developing an application in VB 3.0 . The COMPRESS.EXE utility that
comes with VB 3.0 does not do a good job in compressing files. I noticed
that the COMPRESS.EXE that comes with Access Destribution Kit compresses
files 20% smaller in size.

I noticed that both installation utilities use the same VER.DLL which
contains the function VerInstallFile that is called to decompress in
windows. So I compressed the files with the ADK version and tried to
install it using the VB setup program.

But the VB setup kit would copy the files without decompressing them,
even though the VerInstallFile call to VER.DLL returns 0 when called from VB,
which I assume means no error.

Note that the COMPRESS.EXE of the ADK has a lot of switches compared to
that of the VB. Example it can select which algoritm to use, split files,...

My question is: Has anyone found a better freeware/shareware setup utility
that compresses better that the VB COmpress.exe ? Is there a way around
to use the COMPRESS.exe of the ADK and call the functions successfully from VB?

Thank you very much.

My only question is: When you compressed the files, did you use the
"-r" switch? This renames the files with the "_" extension and stores the
last letter of the extension in the file header.

There are ZIP utilities for VB Available.  CICA has them.

If you are looking to compres for install WISE Install does a pretty great
sqeeze on the files.
