extraction

Anybody can help show examples of using libarchive to extract ZIP files to a specified folder? It looks like the sample programs provided ( untar.c , tarfilter.c and minitar ) all extracts the archive to the current working directory. Is there a way to say "extract to this folder and below" to libarchive and not clobber the program's active folder? One of the main drivers is that the extraction code will be run in a background thread, and thus changing the program working directory may create problems. Also this will be used in an iOS application (iPhone, iPad), which is picky on what folders

I want to distribute only a single .exe, however, at runtime I would like it to extract some embedded image resources to the users hard disk drive. Can I, and if so, how? Use Delphi's TResourceStream. It's constructor will find and load the resource into memory, and it's SaveToFile method will do the disk write. Something similar to this should work: var ResStream: TResourceStream; begin ResStream := TResourceStream.Create(HInstance, 'YOURRESOURCENAME', RT_RCDATA); try ResStream.Position := 0; ResStream.SaveToFile('C:\YourDir\YourFileName.jpg'); finally ResStream.Free; end; end; If you can use

I have (same) data saved as a GIF image file and as a PDF file and I want to parse it to HTML or XML. The data is actually the menu for my university's cafeteria.
