Introduction
This article explains how easy it is to generate reports dynamically in a visually rich and appealing format like MS-Word (2000 and above) without using any components, and shows a little workaround for a quirk. It also talks about the connection between Office, XML, and HTML.
Documents can be converted from Word to HTML (File->Save As) and vice versa! To create a dynamic Word report, you will need to generate regular HTML text and apply the required formatting through CSS. You can even incorporate stuff from the database into the Word report. By playing around with MIME settings, you can force the HTML content to be downloaded as a Word .doc file.
Here comes the code
When you save the downloaded Word document and open it, it opens in the Web Layout format. Now, wouldn't it be neater if it opened in the default Print Layout? Well, all you need to do is attach the style properties. Here comes the code:
Public Sub Page_Load(sender as Object, e as EventArgs)
Dim strBody As New System.Text.StringBuilder("")
strBody.Append("<html " & _
"xmlns:o='urn:schemas-microsoft-com:office:office' " & _
"xmlns:w='urn:schemas-microsoft-com:office:word'" & _
"xmlns='http://www.w3.org/TR/REC-html40'>" & _
"<head><title>Time</title>")
strBody.Append("<!--[if gte mso 9]>" & _
"<xml>" & _
"<w:WordDocument>" & _
"<w:View>Print</w:View>" & _
"<w:Zoom>90</w:Zoom>" & _
"<w:DoNotOptimizeForBrowser/>" & _
"</w:WordDocument>" & _
"</xml>" & _
"<![endif]-->")
strBody.Append("<style>" & _
"<!-- /* Style Definitions */" & _
"@page Section1" & _
" {size:8.5in 11.0in; " & _
" margin:1.0in 1.25in 1.0in 1.25in ; " & _
" mso-header-margin:.5in; " & _
" mso-footer-margin:.5in; mso-paper-source:0;}" & _
" div.Section1" & _
" {page:Section1;}" & _
"-->" & _
"</style></head>")
strBody.Append("<body lang=EN-US style='tab-interval:.5in'>" & _
"<div class=Section1>" & _
"<h1>Time and tide wait for none</h1>" & _
"<p style='color:red'><I>" & _
DateTime.Now & "</I></p>" & _
"</div></body></html>")
Response.AppendHeader("Content-Type", "application/msword")
Response.AppendHeader ("Content-disposition", _
"attachment; filename=myword.doc")
Response.Write(strBody)
End Sub

If you wish to dig deeper into other style properties that you would like to implement, create the Word document in the required fashion, save the Word document as an HTML file, and view the source for the style settings. Wonderful, right?
This article just touches the tip of the iceberg. There are other good resources too. Microsoft Office 2000 supports Hypertext Markup Language (HTML) as a native file format. To get a low-down on this technique, you can download the Microsoft Office HTML and XML Reference that describes the files saved by Excel, PowerPoint, and Word when a document, presentation, workbook, or worksheet is saved as a Web page. You can play around with the style settings to create different configurable options for the user to view a downloadable Word document.
MS Word has better support now for HTML. You can even use it as an HTML editor. The Office HTML Filter is a handy tool you can use to remove Office-specific markup tags embedded in Office 2000 documents saved as HTML to give you really lean and mean HTML code. Even the most basic Windows users are well conversant with Word. Generating HTML files could not have got easier than this, and folks new to HTML do not have to get entangled in tags.

Conclusion
This article tip shows a lightweight method to generate a Word document without using any components, and show it in Print Layout. If you have any nifty Office tips related to HTML and XML, please do share.
