Transition from Zip.AppendString to Zip.AddString

Provides instructions for replacing deprecated AppendString method calls with AddString. Visual FoxPro

LOCAL lnSuccess
LOCAL loZip
LOCAL lcPathInZip
LOCAL lcTextData
LOCAL loEntryObj
LOCAL loZe
LOCAL lnIndex

lnSuccess = 0

loZip = CreateObject('Chilkat.Zip')

* ...
* ...
lcPathInZip = "example.txt"
lcTextData = "This is a test"

* ------------------------------------------------------------------------
* The AppendString method is deprecated:

loEntryObj = loZip.AppendString(lcPathInZip,lcTextData)
IF (loZip.LastMethodSuccess = 0) THEN
    ? loZip.LastErrorText
    RELEASE loZip
    CANCEL
ENDIF

* ...
* ...

RELEASE loEntryObj

* ------------------------------------------------------------------------
* Do the equivalent using AddString.

* Instead of returning the zip entry object, we just return success/failure.
lnSuccess = loZip.AddString(lcPathInZip,lcTextData,"utf-8")
IF (lnSuccess = 0) THEN
    ? loZip.LastErrorText
    RELEASE loZip
    CANCEL
ENDIF

* Do the following if you need the zip entry object for what was just appended.
* The newly appended entry is the last one.
loZe = CreateObject('Chilkat.ZipEntry')
lnIndex = loZip.NumEntries - 1
loZip.EntryAt(lnIndex,loZe)

RELEASE loZip
RELEASE loZe
