(Visual FoxPro) Controlling Paths of Files Added to Zip

When appending files to a .zip, it can be difficult to get the paths exactly as you want them. This example describes a way that you can control the path information when adding a single file at a time to a .zip.

LOCAL lnSuccess
LOCAL lnSaveExtraPath

* This example requires 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')

* Intialize the zip object by calling NewZip.
lnSuccess = loZip.NewZip("myZip.zip")

* Add a reference to a file on disk to the zip object.
* (When appending files to a zip, the files are not actually
* read into memory.  References to the file(s) are added.
* When WriteZip is called, the referenced files are streamed in
* and compressed to the .zip.)
lnSaveExtraPath = 0
lnSuccess = loZip.AppendOneFileOrDir("/temp/a/hamlet.xml",lnSaveExtraPath)
* For brevity, this example will not check the return status...

* The saveExtraPath argument, if set, will cause the path information
* passed in the 1st argument to be saved in the .zip.

* To add "a/hamlet.xml", do this:
loZip.AppendFromDir = "/temp"
*  The saveExtraPath argument, if set, will cause the path information
*  passed in the 1st argument to be saved in the .zip.     But the path in AppendFromDir is
*  not added to that path saved in the .zip.     If there is a path in AppendFromDir then the
*  path in the 1st argument must be relative, not preceded by a drive or \.
lnSaveExtraPath = 1
lnSuccess = loZip.AppendOneFileOrDir("a/hamlet.xml",lnSaveExtraPath)

* To add "temp/a/hamlet.xml", do this:
loZip.AppendFromDir = "/"
lnSaveExtraPath = 1
lnSuccess = loZip.AppendOneFileOrDir("temp/a/hamlet.xml",lnSaveExtraPath)

* The zip written here will contain hamlet.xml three times,
* each with a different relative path.
lnSuccess = loZip.WriteZipAndClose()
