That sounds interesting. I've had so many bugs where I've loaded a DLL that
grabbed the resource handle for the application instance that it just makes
me gun-shy.

I think you would be safe enough loading a resource DLL, but you should
not call AfxSetResourceHandle() in a DLL because that will screw up the
application that uses the DLL.

My method of having a resource loader object, which calls
AfxSetResourceHandle() in its constructor and then calls it again to set
the old resource handle in its destructor, works fine from a DLL.

Typically the resource loader object does one modal dialogue, or loads a
string or two and then goes out of scope, leaving the current resource
handle the way it found it.
