Smart Client And Office System Integration Of Applied Research

The current application software is mainly categorized into Fat Client and Thin Client. Fat Client is characterized with rich interfaces, easy development and fast speed of response. But it is run at the client side and thus it is difficult to be extensively deployed and updated. Thin Client executes itself at the server side and no any installment is needed at the client side. In comparison with Fat Client, Thin Client is easy to be installed, managed, updated and is independent of the software environment at the client side. However, Thin Client operates only under the network environment. Furthermore, there are some restrictions on its interfaces, as well as some difficulties in development raised by its infrastructure.Smart Client is a novel model of software, which takes advantages of Thin Client and Fat Client simultaneously. It exploits both network and Web Services to access all kinds of external resources of operating system. Although it is completely similar to be deployed and updated with Thin Client, such as Internet Explore, Smart Client can exploit all the resources of local computer to compute, which is identical with the popular desktop software.Based on XML, WordML in Office 2003 is developed from Word. It inherits the merits of XML as the standard of data exchange.In this thesis, by exploiting the accessibility of Smart Client to XML and Web Services, Office 2003 is designed to be the platform of some applications of Smart Client. We make it possible for users to access business data without leaving Office 2003.First of all, we analyze the format of HTML document and convert it to the format of HTML COM. Then, the format of HTML COM is translated into the format of WordML and finally, into the format of Word. On the other hand, we study how to utilize XSLT and XPath to extract useful information from the document of WordML and transform it into the document of XML and finally, to generate the document of HTML. Furthermore, we introduce how to use Microsoft.net to analyze and access XML. Different from the development in Office, which operates the document of Word by accessing the local objects of Word through COM, some new applications are first constructed from XML in Office 2003, and then a simple order system is implemented.
