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.

integer li_rc
integer li_Success
oleobject loo_Zip
integer li_NumUnzipped

li_Success = 0

// This example assumes 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

li_Success = loo_Zip.OpenZip("qa_data/zips/sample.zip")
if li_Success <> 1 then
    Write-Debug loo_Zip.LastErrorText
    destroy loo_Zip
    return
end if

// 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
loo_Zip.MinDate = "2017-01-01T00:00:00Z"

// Also, only unzip 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 unzipping.

li_NumUnzipped = loo_Zip.Unzip("c:/temp/unzipDir")
if li_NumUnzipped < 0 then
    Write-Debug loo_Zip.LastErrorText
    destroy loo_Zip
    return
end if
