Zip and Keep Open

See more Zip Examples

Zip a directory tree by calling WriteZip instead of WriteZipAndClose. When WriteZip is called, the created zip is automatically opened and the zip object contains references to the compressed zip entries (mapped entries) contained within the .zip. VB.NET

Dim success As Boolean = False

' This example assumes the Chilkat API to have been previously unlocked.
' See Global Unlock Sample for sample code.

Dim zip As New Chilkat.Zip

Dim zipPath As String = "c:/temp/myFiles.zip"

' Initialize the zip object, which also sets the FileName property to the path of the zip to be created.
zip.NewZip(zipPath)

' Append references to files to be zipped.
Dim recurse As Boolean = True
success = zip.AppendFiles("c:/temp/files_to_zip/*",recurse)
If (success = False) Then
    Debug.WriteLine(zip.LastErrorText)
    Exit Sub
End If


' Write the .zip, but don't close the zip file.
' The zip file we just created is automatically opened and the zip object
' now contains entries that are contained within the zip.  (They are memory-mapped entries)
success = zip.WriteZip()
If (success = False) Then
    Debug.WriteLine(zip.LastErrorText)
    Exit Sub
End If


Debug.WriteLine("Successfully created " & zipPath)

' Let's look at what's in the .zip we just created..

Dim numEntries As Integer = zip.NumEntries

Dim entry As New Chilkat.ZipEntry

Dim i As Integer = 0
While i < numEntries
    zip.EntryAt(i,entry)
    If (entry.IsDirectory) Then
        Debug.WriteLine(i & ": " & entry.FileName & " (directory)")
    Else
        Debug.WriteLine(i & ": " & entry.FileName)
    End If

    i = i + 1
End While

' Close the zip file when finished.
zip.CloseZip()
