This Web Query Save agent takes a Microsoft Word or Microsoft Excel file and converts it to HTML.
It then creates a new Lotus Notes document and attaches the converted HTML files and the original Microsoft Office file to respective rich-text fields.
This allows Lotus Notes users to view an HTML version of an attachment via the Web, without having to download and open Microsoft Word or Microsoft Excel.
To implement this, only two forms are required. The first is a form with a file upload control that calls the attached WQS agent. The second is a form called "Document" with four fields: HTMLFilename (text), PrintFilename (text), PrintFile (richtext), HTMLFiles (richtext).
Your Lotus Domino server must be running on a Win32 platform with Microsoft Office 2003 installed, so that the Web Query Save agent can instantiate Microsoft Word or Microsoft Excel through the "CreateObject" method.

As a side note, there are many more interesting things you can do with Microsoft Office documents through automation, including converting PowerPoint files (which this agent unfortunately does not cover). For more details, go to Microsoft Word -> Visual Basic Editor -> Help for reference.
