What do you mean by "datalinklibraries"? If you mean dynamic link libraries, there is a lot of information available, if you would just bother to look for it[^]. The questions that you have been asking in the message boards have been answered many times before, and there is plenty of information avialable. The best source for those answers is not a message board, but searching the existing information. You are of course welcome to ask any question you like in the message boards, but unless you ask more specific questions, you will only get directed to google over and over again.
