I have a large bitmap file that contains pictures of numbers from 0 to 9. I need to get those numbers and use bitblt to copy them on to a picture box. But these numbers will be used often. How can I do this with the least amount of work and resources?

I could load the entire file into memory each time and use bitblt to get the part I need into the box. But that seems like to it would be to slow and to much memory.

Is there anyway I can bitblt one number at a time to a picture box and create a copy of the bitmap in memory and hang on to its DC. Then do the same to the next number and hang on to its DC. So I would have each number in memory with indivdual DCs? I tried to use createcompitabilebitmap but how do I copy the bitmap into that new one?

I hope this makes sense.
