Zip/Unzip stream example

[Oliver]

Hi,

I'm using the PersistenceManager to persist a RadWindow into a database and I would like to know if
it's possible to compress the resulting stream of the SAVE method before save it into my database?

Can you provide me a small example for both scenario?

Here is the scenario 1:
- Persist a RadWindow using the PersistenceManager
- Compress the resulting stream of the SAVE method
- Save the compressed stream into the database

here is the scenraio 2:
- Load the compressed stream from the database
- Uncompress the loaded stream
- Load the RadWindow uncompressed stream

Thank's

Hi Tina,

this is a good start but when I'm trying to compile, I have the following 3 errors:

Error 1 The name 'InitializeComponent' does not exist in the current context D:\xxx\PersistInStreamAndZip\WpfApplication1\MainWindow.xaml.cs 28 4 WpfApplication1

Error 2 'System.IO.Stream' does not contain a definition for 'CopyTo' and no extension method 'CopyTo' accepting a first argument of type 'System.IO.Stream' could be found (are you missing a using directive or an assembly reference?) D:\xxx\PersistInStreamAndZip\WpfApplication1\MainWindow.xaml.cs 48 51 WpfApplication1

Error 3 The name 'InitializeComponent' does not exist in the current context D:\xxx\PersistInStreamAndZip\WpfApplication1\MyWindow.xaml.cs 13 4 WpfApplication1

I'm with VS2008 and I'm on .Net 3.5

Thank's

Hi Oliver,

I updated the solution to use .Net 3.5 and to run in VS2008. However in .Net 3.5 the System.IO.Stream.CopyTo() method isn't supported so you'll need to manually read the stream byte by byte and write the bytes in another stream.

Please have a look at the solution and let me know if it works on your side.

All the best,
