关于email

Question

var
SupportMail:string;
begin
  SupportMail = 'mailto:[email protected]?subject=[csdn for delphi]';
  ShellExecute(0, nil, PChar(SupportMail), nil, nil, SW_SHOWNORMAL);
end;这是最简单的email调用.
但是他不能指定附件和正文.
我是想不但要指定对方email地址而且还要指定附件和正文等等.
望各位大虾指教.

Answer 1

//(1)delphi6中的demo有：好象叫MailDemo
//(2)"C:\PROGRAM FILES\OUTLOOK EXPRESS\MSIMN.EXE" /eml:%1
//(3)利用Mapi接口
//我只是想看看大家还有什么好的idea而已.结贴。
