Objective-C wrapper for 7zip decompress (LZMA library)
Required skills: C Programming, C++ Programming, iPhone, Mobile Phone, Objective C
Objective-C LZMA wrapper
For the purpose of easy to use extracting functions of the LZMA (7Zip) library from the Objective-C applications (for both iOS and MacOS X) appropriate wrapper is required.
LZMA’s C or C++ version of extractor (decoder) is suggested to be used: http://www.7-zip.org/sdk.html
Source code is suggested to be written in-line with Google’s Objective-C style guide (http://google-styleguide.googlecode.com/svn/trunk/objcguide.xml).
Here are the functions required:
- get all of the (compressed) items list from the archive;
- extract single/several item(s) out of the archive;
- extract all items from the archive;
- remove item from the archive.
In case if other functionality is provided by the library, it’s appreciated to give an access to the rest of the extractor functions as well.
For the testing and acceptance purposes, simple Objective-C application, using LZMA Decompress Class with the following (hardcoded) operations is required:
- print list for all of the files at the archive;
- extract predefined files (3) from the archive and put them on the same folder, next to the archive;
- remove predefined file from the archive;
- (if available) print memory consumption for the action done.
Task considered as accepted, once LZMA Decompress Class and it’s sample application will compile and execute successfully on both iOS and Mac OS X platforms.
GUI front-end for iPhone is not required – if application compiles and execute hard-coded test case actions, it accepted as working fine. Mac OS X version is perfectly fine to print all of the output to the console.

COM Wrapper for C Project
e double parameters like future contract positions.
Some systems, e.g., Fidelity's Wealth-Station, require a COM wrapper for a DLL to be used within its tools.
If possible, I would like to have a COM wrapper written for just my short C main(), which would work fine to have my code make all its calls to its regular C functions. If all the functions need COM wrappers, I probably would not be interested, but I'm willing to discuss that path.

Command line wrapper for *existing* QR Code Decoder SDK
inates of the qrcode into the image
3) ESCAPED message contained into the qrcode.
Because the sdk requires a "serial key" the serial key must be loaded from an external .txt file
The full working demo sdk can be downloaded here
http://www.partitek.com/PtQRDecode.htm
It's extremely well documented with code samples and my requests are just basic features the decoder offers.
(in future I will need the same thing but under linux)

7-Zip library for Visual Basic .NET 2005-2008
Hi. I need a windows library (DLL and source code) developed in C# or VB.NET to call it from VB.NET (2005-2008). This library must use 7ZIP's LZMA SDK to compress/expand files and folders (*.*). I can pay you via paypal (5% added), as soon as you show me the library working fine with your own VB.NET sample detailing main 7ZIP compress/expand features (and more if possible). Please send me questions if you need more information.
