A brief introduction to the Chilkat Library, Chikat is a Chicago company developed by the commercial components, the function is complete, detailed introduction can go to the official website self-reading is not outgoing products or can be used, Chilkat support multiple platforms, voice, see more: http://www.chilkatsoft.com/

C + +: http://www.example-code.com/cpp/default.asp Download the corresponding version of the IDE, in case some strange bug, similar to unresolved external symbol __ Report_rangecheckfailure This log can refer to my blog unresolved external symbol __report_rangecheckfailure to solve the idea

Below is the sending of HTML mail via Chilkat, Demo:

Static string& trim (std::string &s) {if (S.empty ()) {return s;  } s.erase (0,s.find_first_not_of (""));  S.erase (S.find_last_not_of ("") + 1);  return s; }//Note: When the string is empty, an empty string will also be returned static void split (string& s, std::string& Delim, vector<string >* ret) {size_t Last = 0;size_t index = s.find_first_of (Delim,last), while (Index! = std::string::npos) {ret->push_back (S.substr (last , Index-last)); last=index+1;index=s.find_first_of (delim,last);} if (index-last>0) {ret->push_back (S.substr (Last,index-last));}} BOOL Sendhtml (string& suser, string& spwd, string& ssmtphost, string& ssubject, string& sTo, STRING&A mp shtmlcontent) {Ckmailman mailman;//unlocks the device, ckmailman the precondition for normal use bool success = Mailman. Unlockcomponent ("30-day trial"), if (!success) {Log (Log_info, "can not be unlock component."); Set up a mailbox server, for example: Smtp.xx.commailman.put_SmtpHost (Ssmtphost.c_str ());//Set Mailbox login username, password mailman.put_smtpusername (suser.c _str ()); Mailman.put_smtppassword (Spwd.c_str ()); CkEmail email;//Set the message header Email.put_subject (SSUBJECT.C_STR ());//send content email. Sethtmlbody (Shtmlcontent.c_str ());//Sender Email.put_from (SUSER.C_STR ()),//Split recipient below, and add to ckemail one by one vector<string > vtos;string ssplit = ";"; Split (STo, Ssplit, &vtos), Vector<string>::iterator ITos = Vtos.begin (); for (; ITos! = Vtos.end (); ITos + +) {if (! Trim (*itos). Empty ()) {//can only add one user or user group email at a time. AddTo ("", Itos->c_str ());}} Modify the message encoding format to UTF8, this is very important, or some Chinese characters will not be very good display email.put_charset ("UTF8"); success = Mailman. SendEmail (email), if (!success) {Log (Log_error, "ERROR happen to send Email:%s!", Mailman.lasterrortext ()); return false;} Finally close the link success = Mailman. Closesmtpconnection (); if (success! = True) {Log (Log_info, "Connection to SMTP server not closed cleanly."); return true;}

It is important to remind that if the message contains Chinese, it must pass Email.put_charset ("UTF8"); The encoding format of the message is converted to UTF8, so that the Chinese cannot be displayed properly by ASCII code.
