integer li_Success
oleobject loo_Zip
oleobject loo_Entry
string ls_FileContents

// 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

li_Success = loo_Zip.OpenZip("qa_data/zips/EC16100.zip")
if li_Success = 0 then
    Write-Debug loo_Zip.LastErrorText
    destroy loo_Zip
    return
end if

// Get the 1st file in the .zip
loo_Entry = create oleobject
li_rc = loo_Entry.ConnectToNewObject("Chilkat.ZipEntry")

if li_Success = 0 then
    Write-Debug loo_Zip.LastErrorText
    destroy loo_Zip
    destroy loo_Entry
    return
end if

ls_FileContents = loo_Entry.UnzipToString(0,"utf-8")
Write-Debug ls_FileContents
