Yes, and Yes.

First, to put icons into a DLL you specify them in the .RC file for the DLL.
(The only way to put them into a DLL is to use RC to stuff 'em in.)  The
process is just the same as for puting resources into an .EXE file.

Second, to use them, you can use the following:  (*warning, this is Windows
2.0 code, since I don't do 3.0 dev I don't know if these have changed
slightly or not...)

    hLib = LoadLibrary(lpLibFileName);
/* 
 *  or
 * 
 *  hLib = GetModuleHandle(lpLibFileName);
 *
 *  if the library is already loaded
 */
    hIcon = LoadIcon(hLib, lpIconName);

Be aware that keeping the icon handle after the library is unloaded can
cause problems....
