I want to search a string (say s1) in another string (say s2) and replace the search string (s1_ with another string (r1) .

Is there a function?. I do not know much in VB. So please give the function or, the logic to do the above.

I know VisualFoxpro. The same function is available in VFP as
------strtran(s1,s2,r1)--------.

What is it's equilant function in Visual Basic.
Also suggest where can I clarify my doubts in SQL Plus.
