junaids your server also has to run windows to work with com calls in you application. Most servers run on linux. And the server has to have a recent office version on it too as only that version will be able to convert the most formats.
There are a few classes that let you extract content from word documents but none of the ones i found support all word versions. The same goes for pdf classes.
Proprietary binary files, like word docs and pdf, are hard to convert because there is no information how to retrieve the actual data the file contains. And then i leave out how the document is styled.
Because you can't do much with the files developers told the users to copy the content and paste it in a form field. If the form field has an editor functionality it will have a function to clean up the word doc styles but it is not 100% correct.
As dam1an mentioned you can go the easy way and let the document have a standalone status. Make it possible to upload or download them but not have the option to show them in the context of the site.
