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.

Procedure Test
    Boolean iSuccess
    Handle hoZip
    String sZipPath
    Boolean iRecurse
    String sTemp1

    Move False To iSuccess

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

    Get Create (RefClass(cComChilkatZip)) To hoZip
    If (Not(IsComObjectCreated(hoZip))) Begin
        Send CreateComObject of hoZip
    End

    Move "c:/temp/qa_output/out.zip" To sZipPath

    // Initialize the zip object with the path of the .zip to be created.
    Get ComNewZip Of hoZip sZipPath To iSuccess

    // 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
    Set ComMinDate Of hoZip To "2017-01-01T00:00:00Z"

    // Also, only append files having a last-modified date less than the end of 2020
    Set ComMaxDate Of hoZip To "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.
