VintaSoftTwain.NET SDK is a pure .NET library which allows to control work of scanners, cameras and any other TWAIN devices. With this library you can fully control the image acquisition process, use the automatic document feeder, clean up images using noise removal, auto border crop, blank page detection. Acquired images can be saved to local disk or into table of SQL database, images can be uploaded onto Web or FTP server. Supported image formats: BMP, GIF, JPEG, PNG, TIFF, PDF. Library was tested and has examples of use in: VB.NET, C#, ASP.NET.

TCPTester is a load/performance testing tool which sends the testing messages (requests) as byte arrays over the net by tcp protocol. The destination of these messages is an Application accessed by means of a "host: port" pair. Parameter "host" is a character name of server not an ip address. Scenario file (scenario.ini) describes a number of established connections, requests intensity, starting delay, time of a testing for every testing message.
This tool differs from famous products like IBM (Rational) and HP (Mercury) in a way that it isn’t based on traffic produced by User’s GUI but it sends the messages (requests) of special format over the net (tcp) connections. One should describe the messages (requests) manually based on understanding of tested software application. These message descriptions should be saved in xml files. This tool seems to be useful in cases when the testing load should be generated not from User’s workstation but from, say, one software application component to another software application component. In this case we are able to simulate sending of (N) requests per time over (L) tcp connections.
