(PureBasic) 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.

Procedure ChilkatExample()

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

    zip.i = CkZip::ckCreate()
    If zip.i = 0
        Debug "Failed to create object."
        ProcedureReturn
    EndIf

    success.i = CkZip::ckOpenZip(zip,"qa_data/zips/sample.zip")
    If success <> 1
        Debug CkZip::ckLastErrorText(zip)
        CkZip::ckDispose(zip)
        ProcedureReturn
    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
    CkZip::setCkMinDate(zip, "2017-01-01T00:00:00Z")

    ; Also, only unzip files having a last-modified date less than the end of 2020
    CkZip::setCkMaxDate(zip, "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.

    numUnzipped.i = CkZip::ckUnzip(zip,"c:/temp/unzipDir")
    If numUnzipped < 0
        Debug CkZip::ckLastErrorText(zip)
        CkZip::ckDispose(zip)
        ProcedureReturn
    EndIf

    CkZip::ckCloseZip(zip)


    CkZip::ckDispose(zip)


    ProcedureReturn
EndProcedure
