how to change exe file to dll?

Hello Everyone,

I don't know how to convert jpg to the wmf?
I have download one software named magic convert
,it can save jpg as wmf.But it is an exe file.
So I want to change the exe to dll at first so that
I can use the dll's functions in my vc project.
Can you tell me how to realize this?

Thanks a lot.

you can't do that without the source code. You can however lauch the entire program from within your program, but you cannot call a specific function.
