Every program can be reduced to one instruction which doesn't work.

I just had a look for ~5 seconds and saw your problems:

a) AutoRedraw of the picture buffer must be TRUE

b) You draw the picture too many times and to far away

Look:

-
'Your code (this method is thought for tiles)
For A = 0 To picGameArea.Width / BackGround.W
For B = 0 To picGameArea.Height / BackGround.H
'Think: A * BG.w is too far away ;
BitBlt BackhDC, A * BackGround.W, B * BackGround.H, BackGround.W, BackGround.H, BackGround.DC, 0, 0, vbSrcCopy
Next
Next

'---

'My code (a bit shorter)
BitBlt BackhDC, 0, 0, BackGround.W, BackGround.H, BackGround.DC, 0, 0, vbSrcCopy

I want it to be tiled. It is a big tile. It is a back ground.

Well, slipt your BG up in tiles and store the indexes in a map. However it's slower than draw one big BG...

Why can't I just use that procudur for tiles?

[Fox]

Oh, you can.

Look, say the BG is 300x200 and one tile is 10x10 so you have a map which is Map(30,20) and a tile array with 600 tiles. That doesn't make any sense, it's better and faster to draw the BG with one call.
But if you have a tile array with some grass or flower tiles and draw them more than once on the screen, then it's better to make it tile based.

Is that ok?

[*Super Sniper*]

It is just a very big tile. Sometimes the form(and the drawing area) will be bigger or smaller.
