Hello Experts -

While trying to figure out how to test a string to determine if it held numeric data, I came across a web site that claimed that the functions found in the old standby VB were accessable in VB.NET.

Specifically, the site said:

"Looking for IsNumeric in VB.NETt

"I was wondering why a VB.NET class file was throwing up errors when I called the IsNumeric function the other day. After some googling i found out from Roy Osherove’s blog that you now need to import the Microsoft.VisualBasic Namespace to use this and a bunch of other once standard functions."

Is this true? If so, how exactly woud I go about importing the VB Namespace?

Maybe this is already common knowledge. Don't be too tough on me here. I'm only a beginner.
