I want to be able to click the mouse in two points and fill the space between the two points with a line and eventually a wall, how would I go about doing this?. I know there is a function that can assist me in the Win32 API but I''m not familiar enought with it to know. Thanks Gamers, casper

Do you mean in DirectX, or just windows by itself? if you mean just windows, it has a line-drawing function, as well as a rectangle and an ellipse drawing function.
you need a handler to the device content (i.e dc), and you''ll need to declare a CRect strucutre, and pass dc.Rectangle (&myrect); to draw a rectangle. (im assuminf you can handle the handler and other specific details. as for the line, just search throught the help file to find it.
