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.

LOCAL lnSuccess
LOCAL loZip
LOCAL lcZipPath
LOCAL lnRecurse

lnSuccess = 0

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

loZip = CreateObject('Chilkat.Zip')

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

* Initialize the zip object with the path of the .zip to be created.
loZip.NewZip(lcZipPath)

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

* Also, only append 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 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.
