Are you developing something that runs for a webpage or for windows?
I do not understand what you are asking?

well for uploading files into the database using a file upload lets assume uploading images you can do as follows

if (fuPhoto.HasFile) // fuPhoto is the name of file upload
                {
                    string path = Server.MapPath("~/profile/");
                    string file = fuPhoto.PostedFile.FileName;
                    fuPhoto.SaveAs(path + file);
                    string[] ext = file.Split('.');

                    if (Request.Cookies["ProfilePic"] == null && Request.Cookies["Extension"] == null)
                    {
                        HttpCookie profileCookie = new HttpCookie("ProfilePic");
                        profileCookie.Value = ext[0].ToString() + "." + ext[1].ToString();
                        profileCookie.Expires = DateTime.Now.AddDays(1);
                        Response.Cookies.Add(profileCookie);

                        HttpCookie extensionCookie = new HttpCookie("Extension");
                        extensionCookie.Value = ext[1].ToString();
                        extensionCookie.Expires = DateTime.Now.AddDays(1);
                        Response.Cookies.Add(extensionCookie);
                    }
                    else
                    {
                        Response.Cookies["ProfilePic"].Value = ext[0].ToString() + "." + ext[1].ToString();
                        Response.Cookies["Extension"].Value = ext[1].ToString();
                    }
                    if (!ClientScript.IsStartupScriptRegistered("alert"))
                    {
                        ScriptManager.RegisterStartupScript(this, this.GetType(), "Redit", "alert('File has been uploaded..'); 
                    }
                }

now you can save the file by your query into the database..

Ok so yes you are dealing with a webpage.
For security reasons, browser do not let you autofill the the values for file uploads.
You could *TRY* making a customized silverlight control(think activeX or a java applet) for the webpage, but seems a bit exccessive.

@Mudassir,

You wrote in first uploading a file in database. but you may be used file system here. isn't it?
