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.

LOCAL lnSuccess
LOCAL loZip
LOCAL lnNumUnzipped

lnSuccess = 0

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

loZip = CreateObject('Chilkat.Zip')

lnSuccess = loZip.OpenZip("qa_data/zips/sample.zip")
IF (lnSuccess <> 1) THEN
    ? loZip.LastErrorText
    RELEASE loZip
    CANCEL
ENDIF

* 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
loZip.MinDate = "2017-01-01T00:00:00Z"

* Also, only unzip files having a last-modified date less than the end of 2020
loZip.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.
