Although nothing we suggest here can guarantee a successful user interface, a bad user interface will certainly guarantee that no one will use your program. However, with the rapid pace of advances in computing, the definition of what is a “good” interface will surely keep changing. Consider, for example, the process of setting a VCR clock. Early VCR clocks were programmed with buttons and switches, but this method was soon replaced with onscreen displays. Now a broadcast signal makes the whole process automatic in some models. Like the VCR example, your Visual Basic user interfaces will evolve over time, as the industry sets new standards and you learn how to best meet your users’ expectations.
