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。
