Ya minna.

I've got a problem. I'd like to compress the stream data somehow. I've stored a record in a TFileStream object. Can you give me some hints/snippets?

Greetings!

Take a look at DCPcrypt and TurboPower Abbrevia for stream encryption and compression libraries. Both work quite well and while they may be dated, they are (IMHO) the best libraries around.

I use Zlib and Bzip. Both are excellent, but the latter gives better ratios to uncompressed data.

If you dont mind using zlib you could use this:

I was also able to find HKStreams:

But I have no idea how good it is.

else have alook at this list:

I have used HKStreams in a commercial app, it's very good and does both compression and encryption.

I have also used zlib which again is very good
