IPWORKSZIP_EXTERNAL int IPWORKSZIP_CALL IPWorksZip_SevenZip_Set(void *lpObj, int propid, int arridx, const void *val, int cbVal);

Default Value

""

Remarks

Normally you should set ArchiveFile before invoking Scan or Extract. If you prefer to read the zip file from memory you may set ZipData instead. ZipData should be set to the entire contents of the zip file; this will allow you to read from the archive without writing any temporary files to disk.

If you would like to extract data from the archive without ever writing to disk you should also set WriteToProgressEvent to true, and after invoking Scan, you should set the value of FileDecompressedName for each file in the Files collection to an empty string. Then, when you invoke Extract (or ExtractAll) the data will be provided in the Progress event.

This property is write-only. Note that modifying a zip file stored in ZipData is not supported, so Append, Delete, etc., will throw exceptions.

This property is write-only and not available at design time.
