Dear John,
Hossein, if you'll post a description of what you really want to do, then we might be able to suggest a better idiom for you to follow.
You are too nice to me because of keeping track of my issues so much! But I don't have any seroius work to do on this latter topic, and your previouse answers were enough for my application. The only point is that I was trying to purge my mistake. That's all! But if you want to know about the reason behind my first question, I'm going to define a new "holder" object (named so by Bjarne Stroustrup), that is described in an artocle, which I'm writting these days. I would be pleased if I can post a proposal for that object to Boost, but I don't know how. You will help me if you can tell me about the way. Thanks, --Hossein __________________________________ Do you Yahoo!? The New Yahoo! Search - Faster. Easier. Bingo. http://search.yahoo.com
