>Your suggestion works like a charm. What amazes me is that you came up with the whole thing (design, bit operations, etc.) in less than 10 minutes. You are very smart. Thank you.


You're welcome - and I have always liked bit operations (and, or, xor, not)

BTW, this technique is very common - look for example at the MessageBox() parameters
