How about a Regular Expression?

A simple solution would be to write your own function that also recognizes empty tokens. It could look like this:

C++

CString MyTokenize(CString& source, const LPCWSTR& delimeter, int& first)
{
    CString token;
    int count, end = source.Find(delimeter, first);

    if (end != -1) {
        count = end - first;
        token = source.Mid(first, count);
        first = end + 1; // next token
    }
    else {
        count = source.GetLength() - first;
        token = source.Mid(first, count);
        first = -1;    // last token
    }
    return token;
}
