HasMoreData Property
Shows whether or not there is more data in the gzip archive.
Syntax
__property bool HasMoreData = {read=FHasMoreData, write=FSetHasMoreData};
Default Value
false
Remarks
The Gzip format described in RFC 1952 allows multiple gzipped data members to be concatenated into a single file. However, due to the nature of the algorithm it is impossible to determine the number of data members until after the entire archive has been decompressed. The HasMoreData property can be used to cycle through the archive and extract each file.
Simply set the ArchiveFile and ExtractToPath properties, then call Extract as long as the component has available data.
Note: the component will not update FileDecompressedName unless you call Scan or manually set FileDecompressedName on each loop before calling Extract.
Example (Extracting Multiple Files)
ZipControl.ArchiveFile = "c:\temp.zip"ZipControl.ExtractToPath = "c:\extracted\"Do ZipControl.Scan() //here you may inspect the file name in <a href="Gzip_p_FileDecompressedName.htm">FileDecompressedName</a> prior to extraction ZipControl.Extract()While ZipControl.HasMoreDataThis property is read-only.
