LOCAL loZip
LOCAL lnSuccess
LOCAL lnRecurse

loZip = CreateObject('Chilkat.Zip2')

*  Any string unlocks the component for the 1st 30-days.
lnSuccess = loZip.UnlockComponent("Anything for 30-day trial")
IF (lnSuccess <> 1) THEN
    =MESSAGEBOX(loZip.LastErrorText)
    QUIT
ENDIF

*  Initialize the zip object.  Because we're creating
*  a self-extracting EXE in this example, the filename
*  passed to NewZip will never actually be created.
lnSuccess = loZip.NewZip("notUsed.zip")
IF (lnSuccess <> 1) THEN
    =MESSAGEBOX(loZip.LastErrorText)
    QUIT
ENDIF

*  Append a directory tree.  The AppendFiles does
*  not read the file contents or append them to the zip
*  object in memory.  It simply appends references
*  to the files so that when WriteExe (or WriteZipAndClose,
*  or WriteZip, etc.) is called, the files are compressed
*  and added to the archive.

lnRecurse = 1
loZip.AppendFiles("c:/temp/a/*",lnRecurse)

*  Write "archive.exe"

lnSuccess = loZip.WriteExe("archive.exe")
IF (lnSuccess <> 1) THEN
    =MESSAGEBOX(loZip.LastErrorText)
    QUIT
ENDIF
