Don't feel alone. I always get my first implementation of using
TBase64Decoding/Encoding wrong. So much so, that I annotated my FCL INF
documentation with a working code example. :-)

Simply compressed.
The example is using a file, but the real app uses streams in memory.

I'm working directly in memory. The example is using files, but just in example.
Thanks.

Ok, it works now.

tip) and the function Base64Decode from WST framework
http://svn.code.sf.net/p/lazarus-ccr/svn/wst/trunk/
For some reason the function DecodeBase64 from Synapse doesn't work.
It receives an AnsiString. Instea

Perhaps have a look at zlibar. The main, and only, unit contains these
functions:

Hi,
I have streams compressed using GZip. I get these streams from WebServices.
So, how can I decompress these streams only in memory?
I've tried to use zstream unit, that contains TGZFileStream class.
Unfortunately this class works only using files. Then I saved the
stream in a file (data.txt) a
