Here is a basic function I have:
bool MimeDocument::GetExistingAttachment( std::string const& filename, std::vector<MessageAttachment> const& attachments, MessageAttachment& attachment ) { using namespace boost::lambda; using boost::lambda::_1;
std::vector<MessageAttachment>::const_iterator it = std::find_if( attachments.begin(), attachments.end(), bind( &MessageAttachment::name, _1 ) == filename );
if( it != attachments.end() ) { attachment = *it; return true; }
return false; }
MessageAttachment::name() has 2 overloads, one that takes 1 parameter and the other that takes no parameter. I'm attempting to call the version that accepts no parameters and returns a "char const*". I want to then compare this value to the local variable "filename". <snip>
If a function is overloaded, you have to help the compiler choose the right overload when you take the function's address. So replace & MessageAttachment::name with something like: static_cast< char const* (MessageAttachment::*)() >( &MessageAttachment::name ) Hope I got the syntax right. -- Eric Niebler BoostPro Computing http://www.boostpro.com
