IntPtr FileHandle;
long StartPos = 0, FileSize;
FileName = "c:\\temp\\Login.txt";
MyFileStream = new FileStream ( FileName, FileMode.Open );
FileHandle = MyFileStream.Handle;
FileSize = MyFileStream.Length;
Response.Write ( "<b>Login: </b>" );
Response.Write ( "<input type=text id=user /> " );
Response.Write ( "<input type=submit value=Submit /><br><br>" );
Response.WriteFile ( FileHandle, StartPos, FileSize );
MyFileStream.Close ( );
