UCCDraw is an ActiveX / .NET Diagram Component that enables you to build Visio-style charts from within your application. It can be used with any .NET Platform

Figure 1:Allows you to create flow charts, vector drawings, raster images and more with the ability to include hyperlinks and various shading and coloring effects. You can group objects together, include images and text, link them together and apply custom drawing effects to create charts similar to Microsoft Visio, Adobe Illustrator, and CorelDRAW.

Figure 2: By purchasing the product you receive the ActiveX / .NET diagram component plus full source code which you are licensed to modify and thus customize according to your needs.

The full source to UCCDraw ActiveX / .NET Control will be included in the XD++ MFC graphics product.

Figure 3: In addition to extending the functionality of XD++ MFC Class Library, UCCDraw Flow Chart / Diagram ActiveX, it also with .NET Component also acts as a layer of abstraction for the Windows GDI. This layer shields you from low-level GDI details so you can concentrate on creating an application design. Because the UCCDraw Flow Chart / Diagram ActiveX , it also with .NET Component extend XD++ MFC Class Library, you can seamlessly integrate UCCDraw Flow Chart / Diagram ActiveX / .NET Control into your Visual Basic programs, Visual C++ programs, browsers, and anywhere an ActiveX / .NET control is allowed.. However, this does not preclude you from customizing the behavior of any of the UCCDraw Flow Chart, it also with  Diagram ActiveX, it also with  .NET Component.

Figure 4: UCCDraw Flow Chart, it also with  Diagram ActiveX , it also with .NET Component enhance the XD++ MFC classes that thinly encapsulate the Windows GDI API by supporting interactive graphics that support high-level drawing actions such as alignment , copying, or sizing objects.

You can develop any application that includes a drawing surface and interaction with graphical objects quickly and effectively using UCCDraw Diagram Component.

Here are some of the possibilities:

• Desktop Publishing -- Like Microsoft PowerPoint, CorelDraw
  
• CAD Application -- Like AutoDesk AutoCad
  
• Classic Flowcharts Application
  
• WorkFlow Application
  
• Development Application -- Like Microsoft Visual C++ Resource Editor
  
• Control Flow Applications
  
• MultiMedia Author Application -- Like Dazzler
  
• CASE software -- Like Visual CASE
  
• Form Editor

Reliability and performance are extremely good. This control is based on a mature body of Visual C++ source code that has been under development for over 4 years and is being used in several products by multiple companies.
