picture painting by bitblt

i am facing a prob while getting a picture from a picture box which is painted by Bitblt API from another picture box . i have 2 picture boxes . in first picture box i have one picture which is mapped to physical path . I paint an area of picture box to the second picture box by Bitblt API and it is painted successfully ...

Now i want to have that painted picture from picture box 2 to one of my active=x control which has a picture box and i have wrapped its picture property to get any picture from outside. how i can get that the picture from 2nd picture box which is painted by Bitblt . I tried with Paintpicture but it shows pic2.picture value 0 and says it invalid pictrue ( may b bcos it is generated thru Bitblt ).
Any solution ??????????????
