How to open zip file using chilkat. can someone help me?

According http://www.chilkatsoft.com/refdoc/vbnetZipRef.html you have to use the method zip.Unzip() or zip.Extract(). That page mentioned you need a path to the zip file as parameter. — Reporter, Jun 30 '11 at 09:16

Using Unzip instead of Openzip should work. Additionally, your code is way too complicated. It should be done as follows:

Dim zip As New Chilkat.Zip()
Dim success As Boolean = zip.Unzip(ZipTargetFile)

If Not success Then
    MessageBox1("File can't open")
    Exit Sub
End If

@user714435 Can you open the Zip file manually? Is it perhaps password encrypted? Alternatively perhaps the library simply cannot cope with this particular zip archive because it uses an algorithm not supported by the library. – Konrad Rudolph Jun 30 '11 at 09:31

In order to get this to work, I needed to use both the OpenZip and Unzip functions (plus CloseZip in order to archive the file after unzipping if not encapsulated in a using statement).

Zip zipHelper = new Zip();
zipHelper.OpenZip(fileInfo.FullName);
zipHelper.Unzip(fileInfo.DirectoryName);
zipHelper.CloseZip();
