DataMatrix Encoder SDK/ActiveX

A Data Matrix code is a two-dimensional matrix barcode consisting of black and white square modules arranged in either a square or rectangular pattern. The information to be encoded can be text or raw data. it can store up to 2,335 text, 3116 digits or 1556 bytes.

The length of the encoded data depends on the symbol dimension used. Error correction codes are added to increase symbol strength: even if they are partially damaged, they can still be read.

The SDK includes API [static library and dynamic library], ActiveX and ASP Component. Using the SDK, you can: · Create Datamatrix barcode symbols from alpha/numerical text/binary. · Output barcode image with the formats such as BMP, GIF, JPEG, PNG. · Render barcode images on any devices, and create device resolution dependent images. · Full controls of the bar code image styles, such as background color, bar color, image quality, rotation angle, x-dimension, captions, etc. · Support Reed-Solomon error correction. · Choose ASCII,C40,TEXT,BASE 256 encoding modes.

ActiveX is the name Microsoft has given to a set of "strategic" object-oriented programming technologies and tools. The main technology is the Component Object Model (COM). Used in a network with a directory and additional support, COM becomes the Distributed Component Object Model (DCOM).

The main thing that you create when writing a program to run in the ActiveX environment is a component, a self-sufficient program that can be run anywhere in your ActiveX network (currently a network consisting of Windows and Macintosh systems). This component is known as an ActiveX control. ActiveX is Microsoft's answer to the Java technology from Sun Microsystems. An ActiveX control is roughly equivalent to a Java applet.

One of the main advantages of a component is that it can be re-used by many applications (referred to as component containers). A COM component object (ActiveX control) can be created using one of several languages or development tools, including C++ and Visual Basic, or PowerBuilder, or with scripting tools such as VBScript.

The ActiveX library can be used to develop application or using it in ActiveX container application such as Internet Explorer, Microsoft Office and etc.Using Microsoft Visual C++, Microsoft Visual Basic,Microsoft Visual J++, Borland C++ Builder ,Borland Delphi, Borland J++ Builderor other development tools support to use COM.

Limitations:

· With 2D barcode encoder and decoder SDK, some of the input element will be replaced with char '*' before encoding, and some of the output element will be replaced with '*' after decoding. · With 1D linear barcode encoder and decoder, some of the input element will be replaced with char '0' before encoding, and some of the output element will be replaced with '0' after decoding. · The Trial version have 30 days' evaluation time, you must remove it from your computer and your application after expiration.
