moving images

I have a moving image....but it leaves a trail....I have a background image also...how can I stop trails :confused: :(

also when I move...it loses its transparency....is that just something with bitblt and drawing too fast??? :confused:

it seems to be fine the first draw...but then when i move the window offscreen and back on to trigger wm paint it loses transparency :(

There is nothing like drawing to fast.
To avoid trails: erase (or recreate) the background that is uncovered by the moving bitmap. To make it look smoother you should consider double buffering with a memDC.
How do you create the transparency effect?
