Hmmm. Have you tried doubling up any single quotes to escape them when
they're in the EmailSubject string? Then you could try just using single
quotes surrounding the EmailSubject part of the restriction.

string test = EmailSubject;

// first clause has single quote within double quotes,
// second clause has 2 single quotes within double quotes.
EmailSubject = test.Replace("'", "''");

Hi Ken,

I did. What I did was to detect the presence of single quote in
ConversationTopic then I will use double quotes in my Restrict criteria.
And
if I detected the presence of double quote in ConversationTopic then I
will
use single quotes in my Restrict criteria. This works out well. But the
problem is when both the single and double quotes are present in
ConversationTopic then I don't know how to write my Restrict criteria.

Regards,
Robin
