Resource Saving Dynamic Word Doc Generation.
Most often in web development we may require to export web content or contents of a database query to some other media such as word. Creating a word document, writing the content and saving it in the web server and downloading at demand is often time and resource consuming. Here is a quick way to dynamically generate the word document using the Http Response.
To start with, lets assume you already have some content ready to write to a word doc as a response to a button click event of your web page.
Response.Clear();
Response.Charset = "";
Response.AppendHeader("Content-Type", "application/msword");
Response.AddHeader("Content-Disposition", "attachment; filename=" + "MyWord.doc");
Response.AddHeader("Content-Length", sb.ToString().Length.ToString());
Response.Write(sb.ToString());
Response.End();
Response.Flush();
/* section (A) */
Here is a way to add a little formatting to the word document. Lets assume you need to make the page orientation to landscape and want to view in the Print View with the zoom 75%. Here is how you do it.
StringBuilder sb = new StringBuilder();
sb.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>My Title</title>") ;
string sStyle = "<!--[if gte mso 9]><xml>" +
"<w:WordDocument>" +
"<w:View>Print</w:View>" +
"<w:Zoom>75</w:Zoom>" +
"<w:DoNotOptimizeForBrowser/>" +
"</w:WordDocument></xml><![endif]-->";
sb.Append(sStyle);
sb.Append("<style>" +
"<!-- /* Style Definitions */" +
"@page Section1" +
" {size:841.9pt 595.3pt; " +
" mso-page-orientation:landscape; " +
" margin:.5in 1.0in 1.0in .5in ; " +
" mso-header-margin:.5in; " +
" mso-footer-margin:.5in; mso-paper-source:0; }" +
" div.Section1" +
" {page:Section1;}" +
"-->" +
"</style></head>");
sb.Append("<body lang=EN-US style='tab-interval:.5in'><div class=Section1>" );
/*Now append the content to be written to the word document.*/
sb.Append("<b>Sample Test <b>");
sb.Append("<div></body></html>");
And use Response.Write() section (section (A) )mentioned in the above to obtain the response as a word document.
As an overview, this is more useful when you want to extract large amount of information in a predefined word format. Such as extracting transaction information from the online bank statement for example.
