In VB.NET 2005, is there an equivalent of the EVAL function available in
MSAccess and javascript?

I need a way to pass a dynamically generated string (like "2+2") to a
function and return 4.

EVAL("2+2") will return 4

Thanks
Bill

Bill here is a possible solution:

This was a very simple example... Please be aware that this will allow
you to run arbitray bits of JScript code - so you might want to put
some kind of verification on the actual expresions passed. You could
probably use a regex to make sure that the expression was really not
code :)
