Hi everyone!
Im sorta new to thes forums and I was hoping i could get some help
I'm making a Tile Map Editor(2d) in VB.net(2005). I got the basics down, i.e, TileSetBrowser, TileMap, able to place tiles on the map, able to place multiple selected tiles on the map.
But i'm having a hard time with extra tools besides "Pencil". The tools i'm talking about are:

Square fill
Circle Fill
Line
Fill
its basicly like in paint except with tiles.

Any help would be apperciated
