(VBScript) Unzip Files in a Date Range

See more Zip Examples

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

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

Chilkat ActiveX Downloads ActiveX for 32-bit and 64-bit Windows

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 assumes 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")

success = zip.OpenZip("qa_data/zips/sample.zip")
If (success <> 1) Then
    outFile.WriteLine(zip.LastErrorText)
    WScript.Quit
End If

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

' Also, only unzip 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 unzipping.
