Re: explicit linking question (6)

You can use LoadLibrary() to load the DLLs at runtime instead of
linking to them at compile time.
However, if you do this you will need to load each function pointer
programatically.

In re 
Dan Demers' question:

There 
is also (with VC6.0 and later) another approach that might get you what you want 
with less effort:the linker optionfor "Delay-Loaded 
DLLs". Despite the name, this does not mean DLLs that 
arechock-full ofdelays, but DLLs that are only loaded when 
needed:

if 
this is of interest, be sure to read the "Constraints" 
article:

I've 
only used them occasionally myself, no problems, but of course that's no 
guarantee.

(Personally, I'd have called them "Delayed-Load 
DLLs").
