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.

    {
    BOOL success;
    HCkZipW zip;
    const wchar_t *zipPath;
    BOOL recurse;

    success = FALSE;

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

    zip = CkZipW_Create();

    zipPath = L"c:/temp/qa_output/out.zip";

    //  Initialize the zip object with the path of the .zip to be created.
    CkZipW_NewZip(zip,zipPath);

    //  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
    CkZipW_putMinDate(zip,L"2017-01-01T00:00:00Z");

    //  Also, only append files having a last-modified date less than the end of 2020
    CkZipW_putMaxDate(zip,L"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.
