This example shows how to encode an Office file as an XML file and how to convert the resulting XML file into an Office file
Convert the file to XML format, and then you can use the Web service,. NET Remoting,winsock, and so on (in which the latter can be transferred without conversion or transfer)
XML solves the problem of data transfer in multi-tier architectures, such as when clients can get server-side Office files with Web services, and then pass them back to the server
As long as the file into XML format, there are a lot of scenarios can be used, and XML is platform-independent, you can use. NET in the server to publish Web services, and then the client
Java Write a applit small program to deal with the file sent over, of course, I cite the example of almost no meaning, it gave us a lot of inspiration.
In addition, if your solution is based on multiplatform, then the interaction between them is best not to use the remote application interface call (RPC), should try to use the document-based interaction,
For example, MSMQ,J2EE's jmq under. Net.
///
There are a lot of classes designed in the example, I don't have too many comments in all the places, and I don't know where to go. See MSDN, this is my first Windows program, there are some wrong places
You are welcome to guide
