 I have 2 questions and 1 statement

 I'm using VS2005 Pro, VB.NET

1) I know how to use a password to protect a zip file

            REM Compression Level: 0-9
            REM 0: no(Compression)
            REM 9: maximum compression
            strmZipOutputStream.SetLevel(9)
            strmZipOutputStream.Password = "passwordstring"

How can I use Encryption on this file?

 I have Imports ICSharpCode.SharpZipLib.Encryption and Dim crypto As PkzipClassicManaged

 But I cannot figure out how to tie this Encryption class to the Zip class.

2) If I have a file, "demo.zip" and I open it only in memory, How could I use 1 or more of the files directly without extracting?

Statement: I have the latest build and get these warnings:

 Warning    1    Load of property 'RunPostBuildEvent' failed.      CreateZipFile

Warning    2    Load of property 'WarningLevel' failed.      CreateZipFile

Any clue why or how to rid this would be great. ;)

 Hi,

No need to tie things together just set the password and it will do the job as you have already noted.  There is only one algorithm supported currently and the password drives it all.  Are you wanting to use rijndael or something else?

Just remember that the 'classic' encryption algorithm is very weak and should only be used to hide tings from casual users.

Cheers,

John.
