Hi<br />
<br />
I am using vb.net 2005 and I'm not very familiar with regular expressions.<br />
<br />
If i had a comma separated list of items in a string, how would i locate the last comma in the list and replace it with ' and '<br />
<br />
for example<br />
<br />
me, you becomes me and you<br />
me, you, barbara becomes me, you and barbara<br />
<br />
thanks a lot
