.NET TWAIN image scanner(Abstract
In Windows imaging applications, the most used API for scanning is TWAIN www.twain.org. Unfortunately, the new .NET Framework has no built-in support for TWAIN. So we have to work with the interop methods of .NET to access this API. This article doesn t explain this interop techniques, and good knowledge of the TWAIN 1.9 specifications is assumed! The sample code included doesn t present a finished library, only some essential steps for a minimal TWAIN adaption to .NET applications.
Details
First step was to port the most important parts of TWAIN.H, these are found in TwainDefs.cs. The real logic for calling TWAIN is coded in the class Twain, in file TwainLib.cs.. As the TWAIN API is exposed by the Windows DLL, twain_32.dll, we have to use the .NET DllImport mechanism for interop with legacy code. This DLL has the central DSM_Entry(), ordinal#1 function exported as the entry point to TWAIN. This call has numerous parameters, and the last one is of variable type! It was f)

UnixShell4osDesign
Unix shell是unix的命令解释程序，用于让用户以一种友好的方式运行程序和执行命令。
本课程设计要求学生在linux下写一个命令解释程序，实现Ksh最基本的功能。即：允许用
户打入一个可执行的程序的名字以及其命令行参数，执行这个程序。同时实现一部分内部命
令（比如cd，详见要实现的命令），以及输入输出重定向等功能。(Unix shell is unix order to explain procedures to enable users to a friendly manner operational procedures and the enforcement of the order. The courses require students to design the linux under orders to write an interpretation of procedures, Ksh most basic functions. : Allows users to enter an executable program and the name of its command line parameters, the implementation of this procedure. Simultaneously part of the internal commands (such as cd, details to be achieved in order), and redirect input and output functions.)
