DLL Class and Resource

[Steve Wheeler]

Hi -
I am trying to create a dll with an embedded class that I create from my
/exe, this is no problem, but I also want to have a RT_RCDATA resource
embedded in the dll that can be accessed from the .exe so what I am
lookingto do is create a kind of hybird resource dll / extension dll. My
development environment is vc7 / unmanaged. Can this be done - it would mean
I only have to ship 1 dll vs 2 dll's (resource only and win32) with my exe.

Thanks

Assuming that the executable implicitly or explicitly loads the DLL I can
think of no reason why it shouldn't work. Of course, passing the proper
instance handle (the DLL's in your case) to the function that loads the
resource makes all the difference.

You speak of "extension" DLL. Is this an MFC DLL? If so, you might want to
post again in an MFC group to see if there are constraints or conventions
imposed by the class library that you have to deal with.
