Let's say you need to put quotes inside a string. The most common way I've seen developers do this is with Chr(34):
dim myString as string = "Hello " + chr(34) + "World" + chr(34)
Some developers choose to define a constant and use that instead:
dim myString as string = "Hello " + kQuote + "World" + kQuote
But did you know you can insert a quote into your string by using two quotes instead?
dim myString as string = "Hello ""World"""
Makes the string a little more legible, doesn't it?
