CAB files:

Microsoft Cabinet Software Development Kit

You can build CAB files using the "MAKECAB.EXE" utility that is IIRC
included in Windows. For extracting CAB files, you can use Microsoft's
"EXTRACT.EXE", which is available on the Windows XP CD or as part of the
Windows XP Support Tools:

<URL: gbl>

Alternative you can use p/invoke on 'SetupIterateCabinet'. A VB6 sample can
be found here:

View and Extract CAB File Contents Programmatically

ZIP files:

The Zip, GZip, BZip2 and Tar Implementation For .NET

The VB.NET Resource Kit contains zipping functionality too (note that the
Resource Kit is not available any more, so the answer applies for the case
that you already have a copy of the Resource Kit):

The Visual Basic .NET Resource Kit

It contains ComponentOne Zip for .NET:

ComponentOne Zipô for .NET

Using J#'s zip functionality:

Using the Zip Classes in the J# Class Libraries to Compress Files and Data
with C#

..NET 2.0 will contain ZIP support too.
