使用ASP生成RTF文档以将数据流传送到Microsoft Word
概要
本文阐述如何使用 ASP 脚本生成 RTF 文件，然后将这些文件的数据流传送到 Microsoft Word。该技术为用于运行时文档生成的 Microsoft Word 服务器端自动执行提供了一种替代方法。

使用 ASP 服务器端自动执行生成 Word 文档存在一些缺点：
性能：Microsoft Word 是进程外自动化服务器，进程外调用执行的时间较长。
可扩展性：作为自动化服务器，Microsoft Word 需要大量开销；因为必须加载 Winword.exe 文件，才能获得 Word 的丰富对象模型的好处。
通过从一开始就生成文档并且不使用 Word 对象模型，可以增强 ASP 应用程序的可扩展性，而且还可以提高性能。下面的示例通过使用此方法，演示了如何使用 FileSystemObject 创建可在浏览器客户端的 Microsoft Word 中解析的 RTF 文件。
第一个示例显示了如何使用 ASP 创建一个 RTF 文档：包含页眉和页脚、包含表并在整个文档中使用不同的文本字体样式和颜色。该示例使用 ADO 访问示例 Northwind Access 数据库的数据，以创建一个 90 多页的文档。
第二个示例演示了如何创建类似于 Word 邮件合并的 RTF 文档。所产生的文档包含页眉和页脚、各种段落格式和分页符，并在整个文档中使用不同的字体样式和类型。该示例也使用 ADO 访问 Northwind 数据库的数据，以创建一个 170 多页的文档。
注意：RTF 规范是生成 RTF 兼容文本文件的公用规范。可以使用下面 Microsoft Developer Network (MSDN) Web 站点的文档规范作为资源，来帮助您创建自己的 RTF 文件。不过，该规范“按原样”提供，并且未得到 Microsoft 技术支持部门的支持。有关 RTF 规范的最新版本，请参见下面的 MSDN Web 站点：
Rich Text Format (RTF) Specification 1.6（RTF 规范 1.6）

ASP 示例 1
下面的 ASP 演示了如何创建一个包含计算数据报表的 90 多页的 RTF 文档。
注意：此代码示例中的变量 sConn 包含 Northwind 数据库的路径。请确认所提供的路径适用于您的 Office 安装。此外，还需要提供对包含 ASP 文件夹的写访问权，才能创建文档。此访问权应限于 Windows NT 域中的特定用户，但对于匿名访问可适用于每个用户。
