Visual basic Tile Map for game

I am just wondering what is the best way of doing this for smoothest operation.  I will be making a tile map that they can right click on the map and move map up and down in the form.  The form will take up about a 4th of the screen and by clicking on castles on the map other forms pop up to give them choices to do things.  I was wondering what would be the smoothest for the map scrolling around, they will be pretty large maps so I cant draw whole map at once.  Things I have seen are api calls and direct x just wondering if anyone out there knows much about this?  If so i will be asking more questions in direct relation to your answer and will keep feeding you points for each question.
Thanks in advance.
