CString and Insertion Operator ( << )

[cilu]

To answer the original question:

Is there an easy way to perform the following?

CString s;
CryptoPP::Integer n;
s << n;

Just use the method Format:

CString s;
CryptoPP::Integer n;
s.Format("%d", n);

Now, probably this isn't exactly correct. I don't know that CryptoPP::Integer is, but I suppose it's a custom class. If it has an operator int() or a ToInt() method, your code should actually look like this:

s.Format("%d", (int)n);

or

s.Format("%d", n.ToInt());

or something like that. I hope you got the idea.
