DXFReader是一个允许浏览、操作、测绘由AutoCAD系统生成的DXF文件格式的图形，同样也可以转化数据格式。 DXF 是Drawing eXchange Format的缩写。它是一种图形索引格式文件可以用来在一种CAD系统和另外一个程序之间进行转化和交互。DXF的输出和输入支持很多不同的应用程序，包括了大多数的CAD系统、文字处理程序、桌面工具等。DXF CAD格式已经变成了一个基于CAD工业的计算机标准文件，可以被众多的CAD系统读写的格式文件。 使用DXFReader 产品你可以轻松实现从图形数据文件中读取图形信息甚至每一个图形实体，并对其进行数据操作，在您的开发环境中直接分析数据。 -err

如何给ActiveX传递参数的例子，注意其中的IMP单元中的set和get,用VARIANT传递参数，程序中转换-How to pass parameters to the ActiveX example, pay attention to which IMP unit set and get, by passing VARIANT parameters, the conversion process

web中使用Fastreport在ActiveX调用打印例子说明： 1.需要安装fastreport控件 2.执行regsvr32 printx.dll,在delphi环境下就执行run菜单=>register ActiveX Server。 3.执行regsvr32 ocxceshi.ocx,在delphi环境下就执行run菜单=>register ActiveX Server。 请先更改程序的数据库路径! diaoyong目录下为在程序调用printx.dll生成htm的例子 php目录下为在程序调用printx.dll的例子,至于Asp请各位自己变换. test.htm为调用ActiveX的例子 路径有可能不对 因个人水平有限,例子请自己完善，但还是可以使用的。-web use the ActiveX Fastreport called Print examples : 1. FastReport controls need to install two. Regsvr32 printx.dll implementation of the Delphi environment run on the implementation of the menu = gt; Register ActiveX Server. 3. Regsvr32 ocxceshi.ocx implementation of the Delphi environment run on the implementation of the menu = gt; Register ActiveX Server. Please change the database procedures path! Diaoyong directory of the procedure call printx.dll generation htm example php directory of the procedure call printx.dll examples as you please Asp transform themselves.

NTGraph2d的控件原码,用于数据2维显示,请参考NTGraph2d的例子学习使用,我都上传了-NTGraph2d control of the original code for the two-dimensional data, please refer to the examples NTGraph2d learning, I have uploaded

VB打印控件的简单例子，虽然简单，但可以用来学习下，我也是从网上下载的-VB Print control of a simple example, although simple, but can be used to study, I also downloaded from the Internet

ActiveX控件是用户自己编写的控件，并能成功地注册到计算机中并被用户编写的程序所调用以实现用户定义的功能，这样可以节省代码的编写时间。VC++和MFC是用于创建ActiveX控件的强大而灵活的工具，就快速开发和使用简便而言，这两个工具是最好的选择。所以我们选用MFC来进行ActiveX控件的开发。本程序我们就来写一个简单的ActiveX控件，程序虽然简单，但是从中我们可以了解到ActiveX控件编写的整个过程。-ActiveX is prepared by the user controls, and the successful registration of the computer users were prepared by the procedure call to achieve user-defined function, it saves the time of writing code. VC and MFC is the ActiveX control used to create a powerful and flexible tool, rapid development and easy to use, the two tools is the best option. Therefore, we choose to MFC ActiveX development. The procedures we write a simple ActiveX controls, procedures simple, but we can learn from ActiveX controls prepared by the whole process.
