如何用c++实现发邮件功能，急！
想用c++实现   发邮件功能，   谁有原代码

------解决方案--------------------
使用CDO组件吧
#import <cdonts.dll>
try
{
CDONTS::INewMailPtr spNewMail(__uuidof(CDONTS::NewMail));
spNewMail-> From = _T( "YourName ");
spNewMail-> To = _T( "SomeName@SomeDomain.com ");
spNewMail-> Subject = _T( "Testing ");
spNewMail-> Body = _T( "Put your message here ");
spNewMail-> AttachFile = _T( "c:\\AnyFileYouWant ");
spNewMail-> Send();
}
catch(_com_error &ComError)
{
// Error handling goes here
}
