Der PC wird schon lange nicht mehr nur als einfacher Computer verwendet, sondern hat sich zu einem Universalwerkzeug entwickelt. Dieses Buch richtet sich an diejenigen, die vorhandene oder selbstgebaute Hardware über den Computer steuern wollen. Der Einsatz von Visual Basic für die schnelle Entwicklung von Elektronikapplikationen öffnet Ihnen eine Welt, die über die Anschlüsse des PCs hinausreicht. Sobald Sie sich mit Visual Basic, seiner Entwicklungsumgebung und den angebotenen Toolsets vertraut gemacht haben, werden Dinge wie die serielle Kommunikation, Druckerports, Bitbanging, Protokoll-Emulation, die ISA-, USB- und Ethernet-Schnittstellen und die Fernsteuerung von Mess- und Testaufbauten über den GPIB-Bus in allen Einzelheiten behandelt. Zu jedem Punkt gibt es einen übersichtlichen und lauffähigen Programmcode und wo nötig existieren Schaltpläne, mit denen Sie Ihr Projekt in kurzer Zeit einsatzfähig machen können. Darüber hinausgehend erläutert dieses Buch den Umgang mit Debug-Tools bei der Suche nach Hardware-Adressen, den Aufbau einer Verbindung über TCP/IP- und UDP-Sockets und Sie lernen sogar eigene Internetserver zu programmieren. Oder wollen Sie Ihre Hardware über USB oder Ethernet anbinden und mit Visual Basic steuern? Auch die Kommunikation zwischen Programmen, DDE und das neue Grafik-Interface von Windows XP werden behandelt. Alle Programmbeispiele lassen sich mit Visual Basic 5.0, 6.0, .NET oder 2005 kompilieren. Auch die Unterschiede zwischen Visual Basic Classic und Visual Basic NET/2005 sind ausführlich erläutert.
