Achieving rapid performance with a rapid development tool, what a concept!
| Here at VB Profiler | |||
| Howdy! Welcome to my web site. | This site is dedicated to one thing - making VB code run faster. In full applications, ActiveX components and scripts (ASP, WSH), there are always ways of squeezing more horsepower from your hard won code. If you want to read more about why I put this site together, please feel free, but if you're in a hurry, I'll understand. | ||
