Lokad ASP.Net Sales Forecasting
$0 - Lokad.com

Lokad Sales Forecasting for ASP.Net is an open source .Net library (released under BSD license) that features sales forecasts reports for your ASP.Net eCommerce application. If you keep too much inventory, your expenses go up. But if you reduce too much, you have nothing to sell. Smart inventory management is a cornerstone of eCommerce profitability.

Get daily / weekly / monthly sales forecasts for each product of your catalog. Reports can be directly browsed from your website or downloaded as CSV files (compatible with MS Excel). The forecasts rely on the Lokad forecasting technology. Our collaborative algorithms provide improved forecast accuracy even if the input sales data are very limited.

Lokad Sales Forecasting for ASP.Net comes as a stand-alone .Net library that can be deployed through a simple cut-and-paste into your eCommerce application.

Supported eCommerce applications include: AspDotNetStoreFront, Commerce StarterKit, MediaChase eCommerce Framework, .netCART, XSE.NET. Looking for an application not listed here? Do not hesitate to contact the Lokad email support.

BetterStreams
$59 - Jeff Pasternack

.Net library consisting of three classes for simplified asynchronous I/O (AsyncStream), using alternate data streams (AlternateStreams), and efficient stream peeking and seeking (BetterBufferedStream). BetterStreams can easily improve the performance of new or existing applications, sometimes dramatically, with as little as a single-line change to the code.

AsyncStream wraps an existing stream and provides asynchronous I/O via the standard Read(), ReadByte(), Write(), and WriteByte() methods; if called on the wrapped stream directly these would require waiting for I/O to the underlying device (such as a disk) but the AsyncStream asynchronously and automatically fills or flushes its internal buffer from or to the wrapped stream using a background thread and will never block so long as sufficient bytes are available in the buffer. Even if your application logic is already built around synchronous I/O, making it asynchronous typically requires nothing more than wrapping the original stream in an AsyncStream. AsyncStreams also provide elegant exception handling, properties for fine-tuning performance and behavior when desired, and, like BetterBufferedStreams, efficient seeking.

AlternateStreams enables you to read, write, delete, create and list alternate data streams (ADS) in an NTFS file. Under NTFS, each file has a "main" unnamed stream (this is the one the Framework's file I/O classes manipulate) as well as zero or more "alternate" named streams; for example, Internet Explorer uses an alternate stream named "Zone.Identifier" to record which security zone a downloaded file came from. Aside from conveniently storing metadata, they can also be used to create "compound storage" for application data; instead of, for example, sequentially serializing ten objects to the "main" fie stream (requiring the entire file to be rewritten if any but the last object changes) each object can be serialized to its own, individually modifiable alternate stream.

Gears.IFilterHelper
$125 - 9Rays.Net

Text extraction is a task that many developers face every day. As superficially simple as it may sound, this task becomes a real problem when the program should efficiently work with a large number of document types and formats. Writing your own components may require too much time and efforts, which otherwise could have been invested into improving the program core and general optimization. There are many extractors available on the market for each document type, but their aggregate cost may by far exceed your budget for this aspect of your application. If you are looking for an affordable, stable, easy-to-use and elegant solution for text extraction in .NET environment, make sure you don?t miss Gears.IFilterHelper!
Based on a proprietary technology by Microsoft Corp. ? IFilters ? and a corresponding API, Gears.IFilterHelper greatly facilitates and expedites tasks related to extracting text from a variety of sources, from familiar Word documents to Adobe PDF files and much, much more. The goal and motto of Gears.IFilterHelper developers was to turn the complexity of IFilters API into the transparency and intuitive approach implemented in Gears.IFilterHelper, focus on the most important and demanded areas of functionality.

The staple advantages of the library:

- Extracts text from files
- Supports .NET 1.1 and .NET 2.0
- C#, VB.NET and other CLS-compliant languages
- Works with any well-written IFilters
- Also supports Adobe PDF Ifilter 4.0, 5.0, 6.0
- Automatically detects installed IFilters
- Provides extended information about IFilters
Being a simple and focused .NET library written entirely in C#, Gears.IFilterHelper.Net can be used for any .NET application, allowing you to start extracting text by adding just a few lines of code. Apart from being an efficient IFilters wrapper, the component is great at what it was designed for ? getting this text out of a wide assortment of file formats! Try Gears.IFilterHelper and it will never let you down.
