             string filePath = lblresume.Text;             
             Response.ContentType = "doc/docx";             
             Response.AddHeader("Content-Disposition", "attachment;filename=\"" + filePath + "\"");              
             Response.TransmitFile(Server.MapPath(filePath));

Answer 2

Filepath in

Response.AddHeader("Content-Disposition", "attachment;filename=\"" + filePath + "\""); 

Should be physical path; and not styart with: ~ .
Content-type should be "application/ms-word"
