Data Caching Sample
This sample runs only in Microsoft Office Word 2007.
This sample demonstrates how to retrieve data from an XML file, store the data in a Word document’s data cache, and then work with that data from within the document itself or from a Windows Forms application.
The sample is a customer satisfaction survey that is designed to be used offline. Survey information is stored in an XML file; you can load the data into the document's data cache to review or work with the data.
This sample code is intended to illustrate a concept, and it shows only the code that is relevant to that concept. It may not meet the security requirements for a specific environment, and it should not be used exactly as shown. We recommend that you add security and error-handling code to make your projects more secure and robust. Microsoft provides this sample code "AS IS" with no warranties.
