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.

integer li_rc
integer li_Success
oleobject loo_Zip
string ls_ZipPath
integer li_Recurse

li_Success = 0

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

loo_Zip = create oleobject
li_rc = loo_Zip.ConnectToNewObject("Chilkat.Zip")
if li_rc < 0 then
    destroy loo_Zip
    MessageBox("Error","Connecting to COM object failed")
    return
end if

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

// Initialize the zip object with the path of the .zip to be created.
loo_Zip.NewZip(ls_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
loo_Zip.MinDate = "2017-01-01T00:00:00Z"

// Also, only append files having a last-modified date less than the end of 2020
loo_Zip.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.
