tiling effect in DirectDraw

A few questions concerning DirectDraw:

I'm trying to make a tiling effect - use bitmaps of a certain size to fill up the whole screen. What is the best way to approach this?

1) Is it possible to display multiple bitmaps on one surface? If so, how?

2) Is it possible to make the top-left corner of a surface in full-screen mode be anything other than (0,0)?

Thanks for any suggestions.

1) Try looking into BitBlt to copy a single bitmap multiple times, through some manipulations.

2) You can use a user-defined scale:
eg.
Scale (-500, 200) - (500, -200)

The first co-ordinates are what the base of the top-left corner of the screen will be, the second co-ordinates being for the lower-right corner of the screen.Also, using this method sets the ScaleMode to vbUser. Now if you wanted to place a control on the form in the very top left corner you would set its properties to the following:

Text1.Left = -500
Text1.Top = 200


Hope it's helpful.
