C2621 when using "find_first_of" (STL)

[Neo]

Greetings!

I'm now building some VC6-compatible programs under VC7 (VS.NET 2003). Here
is my problem:

vector<wstring>::iterator itArgv;
// ......
if (basic_string<wstring>::npos !=
itArgv->find_first_of(L"ABCDEFGHIJKLMNOPQRSTUVWXYZ", 1)) // error C2621
{
// ......
}

Based on the header file "xstring", "find_first_of" returns "npos" when the
data specified cannot be found. How can I test the return value without
C2621?

Thanks in advance!

Don't make us look it up, what is the text of error C2621?

I assume it's just the typo above causing the problem.

And what is C2621? (I can't be bothered to look it up - you do the work -it
is your problem that you want help with).

Sorry that I forgot to add my build log here.

Perhaps you mean basic_string<wchar_t>. You can't have a
string each of whose elements is a wide-character string.

Your explanation helped me out. Thank you!
