How to create a .zip archive excluding (skipping) files that match a set of wildcarded patterns. Xojo Plugin

Dim success As Boolean
success = 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

success = zip.NewZip("test.zip")
If (success <> True) Then
    System.DebugLog(zip.LastErrorText)
    Return
End If

// Create a string array object with our set of filename patterns
// to be excluded:
Dim sa As New Chilkat.StringArray
success = sa.Append("*.bak")
success = sa.Append("*.tmp")

// Tell the zip object to use these exclusions:
zip.SetExclusions sa

// Append a directory tree.  The AppendFiles does
// not read the file contents or append them to the zip
// object in memory.  It simply appends references
// to the files so that when WriteZip (or WriteZipAndClose,
// or WriteExe, etc.) is called, the files are compressed
// and encrypted.
Dim recurse As Boolean
recurse = True
success = zip.AppendFiles("/temp/a/*",recurse)

success = zip.WriteZipAndClose()
If (success <> True) Then
    System.DebugLog(zip.LastErrorText)
    Return
End If

System.DebugLog("Zip Created!")
