I believe you should be able to do the following:

1. Use the studio wiz to create a win32 dll.

2.  Add a file called say frog.c containing something like
#include <windows.h>
BOOL WINAPI DllMain( HINSTANCE hInstance, DWORD dwReason, LPVOID frog)
{
    return 1;
}
i think the DLL loader needs an entry point called DllMain and the
parameters will allow you to check for stuff, but i don't know why
that would be useful; anyway it doesn't cost much, and using a
resource DLL is a fairly standard thing.

3. Go to project settings/link/input and remove everything from the
object/library modules, you probably don't need any of them.

4. Go to build/set active configuration and select win32 release.
(This minimises your disk image and also improves memory footprint,
and there's nothing to debug).

5. build. This should result in about 30K or so of disk image (depends
on your cluster size or whatever it's called these days). If this is
too big then there are other things you can do, but...

6. Add the resource .rc. The DLL should grow roughly by the size of
your resources. I think that's it.
