    We would like to create a prototype of an intelligent question and answer application. This prototype should be created quickly to demonstrate the idea to managers. If the idea goes through, we will need to implement the entire system as well.The system allows users to answer a set of questions. Each question may be either free-text, multiple choice, number or range of numbers. As the user answers questions, the system analyses the answers in real time, and according to pre-defined rules, it may add more questions to the queue, or show specific instructions to the user.The system also allows managers to define the rules for how to analyze these answers and respond to this analysis.The demo must read and write an XML file containing these instructions, and must actually allow manipulating the rules for analysis and saving them as well. No tests or error handling is needed at this point, it is just a prototype. However, the UI needs to be slick and animated.

    We already have .NET "native engine" wrapper for several source control systems, but now we need to implement support for GitIn the attached archive I"ve included:1) Functional specs2) Technical specs3) Internal coding standards4) Code files / Interfaces needed for the engine to implement5) Examples and test UI application to test the new engine and allow us to also test it when createdAlthough the specs mention Git, Mercurial, and Perforce, for this project we ONLY need Git support to start withProject will be accepted after our internal developer and QA teams receive source code per included instructions, and:a) The code we receive is functional (can be built) and is following supplied internal coding standardsb) Created wrapper engine works well with latest available Git version (1.9.0 or newer)c) Engine quality and performance are sufficient for everyday use in mid-to-large sized source control repositories

    We need a DLL module to extract and parse email messages from Thunderbird or Windows Live Mail inbox files. Thunderbird uses MBOX file format which is actually a big plain-text file in which all email messages are stored. Windows Live Mail saves each email message as an EML file. EML files are also plain-text files containing email headers, body, and other parts. So the DLL should read each folder, extract each message (either in the MBOX or EML file), parse email headers (Sender"s name and address, Recipients" names and addresses, Date, Subject, etc.), extract body parts (plain-text and HTML, MIME), and send them to our host application.Requirements:- We need fully documented, and compilable source code.- Compiled DLL binary for both Win32 and Win64 platforms must be deployed.- The DLL should be able to parse different encoding and character sets to correctly parse Non-English text in subject, body, or sender and recipient names.- There is a programming interface for communicating with the host application which is developed by us. This interface will be given to the winner developer and the produced DLL should comply with it. The DLL will be tested by us using our own host application.- You can use C, C++, C#, or Delphi as the programming language.- No dependency on 3rd-party library or component is acceptable. You can only rely on your own code or the standard library or framework provided by your chosen programming language.- Performance and resource consumptions are very critical. The faster your code can parse the messages and the less it consumes RAM and CPU, the better it is, and the more chance you have to win the project. Compiled binary demo for testing performance is very welcomed.

    Hello guys,WE need to have someone the knowledge of .NET and Flash.. Here"s what we would like to do. We have lots and lots of Base64 encoded text data which is being retrieved in flash and is then uncompressed/decoded using bzip or some other algorithm in flash action scripting.The Base 64 sample data and the action scripting file (which probably contains information on how the data is being uncompressed) is attached, I want the code in either C# or VB.NET to decode this data. We have quite a few files like this and want someone to work with us on per decryption basis. We aren"t looking to pay more than $75 per decryption, this is an ongoing project and one project will followed by next. WE have too many files, so as much as you can do, we are ready to give you more and more files.. Here"s the sample..Files:Base64 Data.txt contains Base 64 encoded data which is further encoded/compressed by zlib or other functionFlash Action Scripting Decoder.txt contains function that uncompress byte array(ba) which already contains Base64 decoded data.Let us know, how many and how quickly you can do these per day..? Please only bid, if you can really do it, and are able to successfully understand the scope of the project and do the sample. If you do, please let us know your bid and timeframe for the batch of 50.

    This program will allow for visual preparation of TIFF files. A list of "DocTypes" will be used to divide a multiple page TIFF into smaller units of documents. The user will be able to visually move a page, or pages of the original TIFF into different documents. The user will be able to rearrange pages inside documents, delete pages, rotate pages and finally commit the finished job. Each document will have one associated DocType assigned to it.Detailed requirements, sample TIFFs and sample code are attached.

    Hay una esquema de funcionamiento de pago. En esta esquema hay dos conexiones, GATE (sistema propio) por un lado y por otro Sistema Pagos (web money etc...). La nesesidad es tener un "modulo" o lo que sea, escrito en PHP, para comparar las transacciones despues de cierre de un dia operativo. Y luego formar un report XML. Con diferecias, errores etc (el formato se puede mostrar). El fichero debe contener el estado de transacciones en ambos lados (gate, sistema pagos)... Se supone que para cada sistema de pagos seria un desarollo propio. Pero la idea principal es hacer un modulo comun. Para empezar el proyecto consiste en desarollo de modulo, generacion de ficheros para dos sistemas Web Money y Qiwi.
