(PowerBuilder) 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.

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

loo_Zip = create oleobject
// Use "Chilkat_9_5_0.Zip" for versions of Chilkat < 10.0.0
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

// Intialize the zip object by calling NewZip.
li_Success = loo_Zip.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.)
li_SaveExtraPath = 0
li_Success = loo_Zip.AppendOneFileOrDir("/temp/a/hamlet.xml",li_SaveExtraPath)
// 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:
loo_Zip.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 \.
li_SaveExtraPath = 1
li_Success = loo_Zip.AppendOneFileOrDir("a/hamlet.xml",li_SaveExtraPath)

// To add "temp/a/hamlet.xml", do this:
loo_Zip.AppendFromDir = "/"
li_SaveExtraPath = 1
li_Success = loo_Zip.AppendOneFileOrDir("temp/a/hamlet.xml",li_SaveExtraPath)

// The zip written here will contain hamlet.xml three times,
// each with a different relative path.
li_Success = loo_Zip.WriteZipAndClose()
