You'll need a third party component or library.

We use SharpZipLib available from http://www.icsharpcode.net/OpenSource/SharpZipLib/

More commercial components exist. I believe Xceed do one.

Thank you.

1. I program in VB.Net 2003, can I use SharpZipLib ?

2. I downloaded both the NET 2.0: Compiled assembly with documentation and
install scripts and Source code and samples. To install it, do I run the
installGAC.bat ?
Do I need to create a sub-folder called BIN before I run this bat file ?
Even after creating the BIN folder, when I run this bat file from the
command prompt, I got the error "Failur adding assembly to the cache: The
system cannot find the file specified". How can I fix this ?

3. When I try to include ICSharpCode.Sha rpZipLib.dll in the Reference of my
VB.Net project, I got an error : "A reference to
c:\download\zip \ICSharpCode.Sh arpZipLib.dll could not be added. This is not
a valid assembly or COM component. Only assemblies with extension 'dll' and
COM components can be referenced. Please make sure that the file is
accessible, and that it is a valid assembly or COM component.

Thank you.

Yup but you will need to use the Framework V1.1 version

Both versions are available here http://www.icsharpcode.net/OpenSourc.../Download.aspx
but you do need the 1.0/1.1 version.

2. I downloaded both the NET 2.0: Compiled assembly with documentation
and
install scripts and Source code and samples. To install it, do I run
the
installGAC.bat ?
Do I need to create a sub-folder called BIN before I run this bat file
?
Even after creating the BIN folder, when I run this bat file from the
command prompt, I got the error "Failur adding assembly to the cache:
The
system cannot find the file specified". How can I fix this ?

I don't think I can help you here. I don't use it it the GAC, prefering to
use XCopy deployment and just lumping the dll into my own dir alongside my
exe.

3. When I try to include ICSharpCode.Sha rpZipLib.dll in the Reference
of my VB.Net project, I got an error : "A reference to
c:\download\zip \ICSharpCode.Sh arpZipLib.dll could not be added. This
is not a valid assembly or COM component. Only assemblies with
extension 'dll' and COM components can be referenced. Please make sure
that the file is accessible, and that it is a valid assembly or COM
component.

Again I think this is down to using the .Net 2.0 version when you can only
code with .Net 1.1 assemblies and code in VS2003

I hope this helps

Did you mean to just copy the ICSharpCode.Sha rpZipLib.dll into the same
directory where my VB.Net project is ?

Is there any ZIP library or component that I can use with Framework 2.0 ?

Well I have a Dir Structure like the following

Integration
Integration\3rd Party
Integration\Sol ution1
Integration\Sol ution1\Project1
Integration\Sol ution1\Project2
Integration\Sol ution1\Project3
Integration\Sol ution1\Release
Integration\Sol ution2
Integration\Sol ution2\Project1
Integration\Sol ution2\Project2
Integration\Sol ution2\Project3
Integration\Sol ution2\Release

So that I can reference 3rdParty Dlls from somewhere under 3rdParty from
any of my projects in any of my solutions
Then I set copyLocal to true (in most cases) which ends up with the dll being
copied by vs into the bin dir alongside the generated exe.

A couple of points....

1.You said you were using VS2003. This will not allow you to use or link
to dotnet 2.0 code/assemblies
2.If you do upgrade to VS2005...
2a....you can use the same .Net 1.1 libraries as they are (largely) forward
compatible.
2b....you can use the SharpZipLib .Net 2.0 version available from the same
site
3....I'm sure xceed do versions of their Zip software for all the framework
versions
4....Net 2.0 comes with some build in zip classes. Check out the 'System.IO.Comp ression'
NameSpace

I hope this helps :)

Thank you.

There should be a .NET 1.1 version of SharpZipLib for you to use in your
project

Thank you.

I would like to use the .NET 2.0 System.IO.Compr ession.
From the MSDN website at
http://msdn2.microsoft.com/en-us/lib...am(vs.80).aspx
the example shows how to compress then decompress a file.
When decompressing, it is not clear from the example how can I pass the file
name to GZipStream ? The example passes "ms" (a memorystream) to GZIPStream,
not a file name. How can I pass the file name to GZIPStream ?

Thank you.
