How to create a .zip archive excluding (skipping) files that match a set of wildcarded patterns. B4X

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 ChilkatZip
zip.Initialize("zip")

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


'  Create a string array object with our set of filename patterns
'  to be excluded:
Dim sa As ChilkatStringArray
sa.Initialize
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 = True
success = zip.AppendFiles("/temp/a/*", recurse)

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


Log("Zip Created!")
