[itmagina]

Hi everybody, I am using shock wave flash control on a dialog. I able to play the movie file(.swf file) But I want to make the background as transparent while playing the swf file.There is an article named "transparent flash control in plain C++" that solved this problem, but the usage of cpu is too high.Does someone have a solution? Thanks!

The performance of iceProjector is better than most other programs'. It's a good idea to transparent the flash with windows region.
