7-Zip (De)Compression DLL

The project is the encapsulation of 7-Zip functionality in a DLL that can be called by any Windows application (and specifically, a Delphi application). The requirements for the DLL are as follows:

1) Use STDCALL/WINAPI calling conventions

2) Provide callback parameters for events

3) The DLL must encapsulate the ENTIRE 7-Zip functionality. Base starting projects can be the 7-Zip GUI project, or the 7-Zip Command Line project. In particular:

- listing of files inside archives. if archive is password protected, a callback must ask for the password.

- random decompression of files inside archives. files across multiple different folders inside an archive should be decompressed in a single pass. callbacks must provide extraction progress, the name of the file being extracted, the opportunity to cancel the operation, handlers for overwrite actions (skip/always/never), and the ability to obtain passwords for encrypted files.

- random compression of files into archives. any collection of files should be compressed in a single pass. for instance, some files can be compressed recursively, others non-recursively, in a single operation. the full range of compression parameters in 7-Zip must be available for the compression operation, as well as callbacks for progress reports, etc.

4) An example Delphi project that shows/tests the DLL.

5) The DLL should be written in Visual C++ 6.0/7.0, using the downloadable 7-Zip sources as a starting point.

6) The DLL will work with 7-Zip installed on the target system (it requires 7-Zip).

7) The DLL should support all archive types that are supported by 7-Zip. This is already automatically available with the console or gui 7-Zip projects as a starting point.

In essence, this project is simply converting existing 7-Zip code, which already works exactly as required above either from the command line or from a windowed interface, into a DLL. All the existing behavior is already provided - you just need to package it into a DLL, and instead of outputting progress to a console/window, feed it to callback functions that are provided to the DLL.

The owners of this project are NOT associated in any way with 7-Zip.
