I use this code:
<iframe src="@HttpContext.Current.Server.MapPath("~/Temp/sample.docx")" height="800" scrolling="no" align="top" frameborder="0" >
<p>Your browser does not support iframes.</p>
</iframe>
but I get this error:
The address wasn't understood
Firefox doesn't know how to open this address, because the protocol (d) isn't associated with any program.
You might need to install other software to open this address.
