How to compress and encrypt files in VB6

[FM]

Please help - can any one tell me how to compress and encrypt files within
VB? Thanks.

Of course, you could use API calls for this. But since this is VB, the
easiest solution to me is to use the DynaZip components. They work fine.
Have a look at http://moreinfo.vbonline.com/vbonlin...media/dynazip/

FM,

If you are talking about NT 4.0+, you can use the code at
http://gethelp.devx.com/techtips/nt_.../10min0900.asp to
compress files, directories, etc.

If you are talking about W2K+, then you can use the code at
http://gethelp.devx.com/techtips/nt_...0minNT1100.asp
to encrypt (which also does some compression) a file, directory, etc.
However, compression and encryption (under the API for W2K+) are mutually
exclusive.

I am using Makecab.exe (ships with VB), and it is ok, though it has a dos-like
interface, but i launch it in background from VB and works really fine, with
many options.
It creates standard cab files, very fast, high compression and cryptable.
For more detailed info look at msdn.microsoft.com/workshop/management/cab/diamond2.asp

There is a complete example on the net with VB using CryptoAPI, the API is
implemnted as class. One link is: http://www.freevbcode.com/AuthorInfo.asp?AuthorID=398

For Blowfish-Crypto: http://www.di-mgt.com.au/crypto.html.

There are also a lot of code an the net for compression.

Coming to that, Has anyone tried storing Word files (or for that matter any
file) into Oracle database (as LOB ) or something through a VB aplication?
Please give any info on this subject.
