Hi all! We have been experiencing an issue on site where threads have been missing the latest postings. The platform host Vanilla are working on this issue. A workaround that has been used by some is to navigate back from 1 to 10+ pages to re-sync the thread and this will then show the latest posts. Thanks, Mike.

    This is for an Asp.net (2) regex validator control. Its the default pattern matcher for a valid email address. 
    \w+([-+.']\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*

    How can I modify this to ignore trailing whitespace in the email address being validated?

    Been a while but I think this will do it:

    \w+([-+.']\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*[¬\s]

    Hope that helps

    What I ended up doing in the end was \w+([-+.']\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*\s*

    which ingnores any white space that may be there, including tabs.

    \w+([-+.']\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*[¬\s]

    Only seems to work if there is a single nonbreaking space present..

    I found a suggestion in the Perl FAQ. It includes a link to a script that does a complete check (including contacting the email server). I'm sure both could be ported to ASP.

    Thanks daymobrew but its just for a form processing. It doesn't have to be an existing email address, just as long as its resembles one.
