NO! I'm not going to tell you because I asked you, "Have you read the documentation or checked with the manufacture of the VNC Client you're using!?" and of course I already knew the answer because if you had you'd not need to ask the question if the first place! So either you can't take a hint or your just plain lazy! 
Try RTFM instead of asking questions that are answered by the documentation!
