Hi Dave,
Not hard at all.
First, you have to use an imports statement at the top of your form, as
follows:
Imports System.IO
Imports C1.C1Zip
Then, to zip and subsequently to extract (q & d and you have to make sure
the filenames don't already exist):
Dim mzip As C1ZipFile
mzip = New C1ZipFile
mzip.Create("f:\imcapps\pslips_.zip")
mzip.Entries.Add("f:\imcapps\dbffiles\natlbl.dbf")
mzip.Entries.Add("f:\imcapps\dbffiles\summary.dbf" )
mzip.Close()
MessageBox.Show("now I will move the extracts of f:\imcapps\pslips_.zip into
f:\imcapps")
mzip.Open("f:\imcapps\pslips_.zip")
Dim i, x As Integer
x = mzip.Entries.Count - 1
For i = 0 To x
mzip.Entries.Extract(i)
Next
As a point of information, you can probably get the .chm help file for
componentone.com; also, there is an n/g at componentone.public.net.c1zip
that can offer some help.

I am trying to convert QuickBasic and dos batch files into VB.NET. I
downloaded the resource kit along with the free ComponentOne Zip classes.
The examples that came with the zip utility were not real helpful as I am
relatively new to VB.NET. I need to unzip a file composed of about 20 text
files. Once the file is unzipped, I have a form which allows the user to
edit one of the unzipped text files. I then save the edited version and
now need to zip that individual text file back into the zip file. I know how
to edit the text file but the zipping and unzipping routines are giving me
fits. How do I do this? Thanks in advance for your help.
