TWAIN ActiveX/Plug-in Windows/Mac HTTP Control/SDK

Using Dynamic Web TWAIN in Microsoft Visual Studio .NET

Before opening the accompanied sample applications written in C# and VB.NET, please import the Dynamic Web TWAIN into Visual Studio .NET first. The sample applications are installed with Dynamic Web TWAIN and can be found from the Start Menu.

Microsoft .NET Framework offers a highly productive multi-language environment for developers. In .NET framework, the languages are compiled into Microsoft Intermediate Language (MSIL) output according to the common language specification. In run-time, the intermediate code will be compiled into machine code and then run against the Common Language Runtime.

Under this mechanism, the performance of applications suffers significantly, especially for the image processing applications, like Dynamic Web TWAIN. Dynamic Web TWAIN is developed directly from system API and assembly language to get high performance.

To enable our customers to be able to use Dynamic Web TWAIN in .NET without sacrificing the high-performance of Dynamic Web TWAIN, our policy of Dynamic Web TWAIN in .NET is to take advantage of the interoperability feature of .NET.

The interoperability feature of the Microsoft .NET Framework enables developers to continue using traditional Active Server Pages, Component Object Model applications, and Microsoft Win32 DLLs, making it easier to choose if and when to migrate existing managed code to .NET.

The followings are the steps of importing Dynamic Web TWAIN into .NET. We can see how easy it is.

Start Visual Studio .NET.
From the Tools menu, select Add/Remove Toolbox Items.
In the Customize ToolBox dialog box, check the DynamicWebTwain Class. Click OK to close the dialog box.
From now on, the Dynamic Web TWAIN ActiveX Control can be used in .NET like other controls.
