(Visual FoxPro) Create Zip in a BinData Object

Recursively appends files in a directory tree and writes a zip archive into a Chilkat BinData object.

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

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.Zip')
loZip = CreateObject('Chilkat.Zip')

* Initialize the zip object.  Because we will never actually write a zip file to the filesystem,
* the filepath passed to NewZip does not matter.
lnSuccess = loZip.NewZip("x.zip")
IF (lnSuccess <> 1) THEN
    ? loZip.LastErrorText
    RELEASE loZip
    CANCEL
ENDIF

* Append a directory tree.  The call to 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 WriteBd, WriteZip, or WriteZipAndClose 
* is called, the referenced files are streamed and compressed
* into the .zip output file (or BinData object).

lnRecurse = 1
lnSuccess = loZip.AppendFiles("c:/temp/a/*",lnRecurse)
IF (lnSuccess <> 1) THEN
    ? loZip.LastErrorText
    RELEASE loZip
    CANCEL
ENDIF

* Write the zip archive into the bdZip object.
* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.BinData')
loBdZip = CreateObject('Chilkat.BinData')
lnSuccess = loZip.WriteBd(loBdZip)
IF (lnSuccess <> 1) THEN
    ? loZip.LastErrorText
    RELEASE loZip
    RELEASE loBdZip
    CANCEL
ENDIF

* We could directly access the bytes of the zip archive, or perhaps
* get the zip bytes in base64 format.
lcZipAsBase64 = loBdZip.GetEncoded("base64")
? lcZipAsBase64

* Or the zip can be used by some other Chilkat method call that accepts
* a BinData object as an argument.
