(VBScript) Zip Files in a Date Range

See more Zip Examples

Demonstrates how to use the Zip.MinDate and Zip.MaxDate properties to zip only those files with a last-modified date within a date range.

Note: This example requires Chilkat v10.0.0 or greater.

Dim fso, outFile
Set fso = CreateObject("Scripting.FileSystemObject")
'Create a Unicode (utf-16) output text file.
Set outFile = fso.CreateTextFile("output.txt", True, True)

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

' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.Zip")
set zip = CreateObject("Chilkat.Zip")

zipPath = "c:/temp/qa_output/out.zip"

' Initialize the zip object with the path of the .zip to be created.
success = zip.NewZip(zipPath)

' The MinDate and MaxDate properties use the timestamp date/time string format.
' Here are some examples:
' YYYY-MM-DD (e.g., 2024-07-31)
' YYYY-MM-DDTHH:MM:SS�HH:MM (e.g., 2024-07-31T12:34:56+02:00)
' 2024-07-31T12:34:56Z (the "Z" denotes Zulu time, or UTC)

' Only append files having a last-modified date greater than 1-Jan-2017
zip.MinDate = "2017-01-01T00:00:00Z"

' Also, only append files having a last-modified date less than the end of 2020
zip.MaxDate = "2020-12-31T23:59:59Z"

' You don't need to specify both MinDate and MaxDate.
' You can specify only one or the other if needed.

' The MinDate/MaxDate properties apply to all of the Chilkat methods for appending files.

' Recursively append to the zip object the paths of the files and directories in a directory tree.
' At this point we are not creating the .zip, nor are we reading the contents of the files.
' We are simply appending references to the files and directories in the local filesystem
' that will get processed when WriteZip is called.
