> 3) Close the resulting xxx_TLB.pas file.  This is an annoying feature of
D4
> that, if you have the TLB.pas file open, the compiler doesn't replace it
> until you have recompiled at least once (usually the compiler waits about
> 5 minutes or so, then tells you that the disk version is later than the
one
> loaded into the compiler).  By closing the file, you guarantee yourself
> that you are compiling the version on disk.

> 4) Do a project|build on the project which uses the functions in the Dll.

functions

> that those functions are not registered.

> I can't really say why you get the error most, but not all, the time,
