关于email

[year2000bug]

var
SupportMail:string;
begin
SupportMail = 'mailto:[e-mail]?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.

建议用LCmail元件

呵呵，建议看前几期的《电脑报》！
上面有个这方面的例子。

//(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。。。。
