Help with regex match and replace

[tsteward]

Would anyone be able to knock up a quick routine so I can learn how to implement Regex controls.

I wish to search a string to find all occurrences of "*" some text and "*"
Then replace it with "<b>" the text "</b>"

Playing around with a regex builder I have come up with this code to find the matches:
\*([^\*]+)\*

And this regex to replace the text:
<b>$1<\\b>

So my question is how do I implement this into basic 4 ppc.

Thank you
Tony

Something like:

Sub App_Start
    str = "This is a string: * lskjefklew f* wef wl;efkl;wef * fwel;fkw;lkgweg wegwegweg* WEG* wegjlweg=-3t94=-9t*"
    regex.New1("\*([^\*]+)\*")
    newStr = regex.Replace(str,"<b>$1<\b>")
    Msgbox(newStr)
End Sub
