Iterate over Matching Filenames

See more Zip Examples

Iterates over files within a .zip that match a pattern. In this case, the pattern is "*.pem". This example will open a .zip containing files of type .txt, .cer, .pem, and possibly others, and will iterate over only the .pem files. VB.NET

Dim success As Boolean = False

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

Dim zip As New Chilkat.Zip

' Open a .zip containing PEM files, among other things..
success = zip.OpenZip("qa_data/certs/thawte-roots.zip")
If (success = False) Then
    Debug.WriteLine(zip.LastErrorText)
    Exit Sub
End If


Dim entry As New Chilkat.ZipEntry
Dim pemStr As String
Dim pattern As String = "*.pem"

Dim bHasMoreMatches As Boolean = zip.EntryMatching(pattern,entry)
While bHasMoreMatches = True

    Debug.WriteLine("Entry: " & entry.FileName)

    ' Get the uncommpressed contents of the entry:
    pemStr = entry.UnzipToString(0,"utf-8")
    Debug.WriteLine(pemStr)

    bHasMoreMatches = entry.GetNextMatch(pattern)
