1 下载并注册JMail组件

1.1 下载jmail.dll文件放到C:\Windows\System32文件夹中和项目路径下

下载地址：http://www.onlinedown.net/soft/620751.htm

1.2 注册jmail.dll组件，win+R→regsvr32 jmail.dll

2 新建基于对话框的应用程序

2.1 添加以下控件：

各控件ID参照下面代码。

2.2 在stdafx.h文件中引入JMail组件

#import "jmail.dll"
using namespace jmail;

2.3 初始化类库

BOOL JMail::OnInitDialog() 
{
……
	HRESULT hr=::CoInitialize(NULL);
	if(!SUCCEEDED(hr))
		return FALSE;
}

3 add按钮（添加附件）对应代码：

void CJMailDlg::OnAdd() 
{
	CFileDialog file(true,"file",NULL,OFN_HIDEREADONLY | OFN_OVERWRITEPROMPT, "所有文件|*.*||",this);
	if(file.DoModal()==IDOK)
	{
		CString str;
		str=file.GetPathName();
		GetDlgItem(IDC_EDATT)->SetWindowText(str);
	}
}

4 send按钮对应代码

void CJMailDlg::OnBtsend() 
{
	CString strserver;
	CString strrece;
	CString strsubject;
	CString strbody;
	CString stratt;
	CString strfrom;
	GetDlgItem(IDC_EDRECE)->GetWindowText(strrece);
	GetDlgItem(IDC_EDSUBJECT)->GetWindowText(strsubject);
	GetDlgItem(IDC_EDBODY)->GetWindowText(strbody);
	GetDlgItem(IDC_EDATT)->GetWindowText(stratt);
	GetDlgItem(IDC_SMTP)->GetWindowText(strserver);
	GetDlgItem(IDC_EDFROM)->GetWindowText(strfrom);
	if(strfrom.IsEmpty())
	{
		AfxMessageBox("请填写发信人地址");
		return;
	}
	if(strrece.IsEmpty())
	{
		AfxMessageBox("请填写收信人地址");
		return;
	}
	jmail::IMessagePtr jmsg;
	jmsg.CreateInstance(__uuidof(jmail::Message));
	jmsg->AddRecipient((LPCTSTR)strrece,"","");
	jmsg->Charset = "GB2312"; 
	jmsg->Subject=(LPCTSTR)strsubject;
	jmsg->Body=(LPCTSTR)strbody;
	jmsg->From=(LPCTSTR)strfrom;
	jmsg->MailServerUserName = "name@163.com";
	jmsg->MailServerPassWord = "password";//发送邮箱密码
	jmsg->AddCustomAttachment((_bstr_t)stratt,(_bstr_t)"jmail",VARIANT_FALSE);
	try{
		//jmsg->Send((LPCTSTR)strserver,VARIANT_FALSE);
		//jmsg->Send("smtp.163.com", VARIANT_FALSE);
		jmsg->Send(strserver.GetBuffer(0),VARIANT_FALSE);
	}
	catch(_com_error e)
	{
		CString strerr;
		strerr.Format("%s\r\n错误描述是%s",(LPCTSTR)e.ErrorMessage(),
			(LPCTSTR)e.Description());
		AfxMessageBox(strerr);
	}
	//AfxMessageBox("发送成功");
	//m_status = "sended successfully!";
	GetDlgItem(IDC_status)->SetWindowText("sended successfully!");
}

5 也可以初始化各文本框的值

BOOL CJMailDlg::OnInitDialog()
{
	CDialog::OnInitDialog();
	……
	GetDlgItem(IDC_SMTP)->SetWindowText("smtp.163.com");
	GetDlgItem(IDC_EDFROM)->SetWindowText("name@163.com");
	GetDlgItem(IDC_EDRECE)->SetWindowText("name@163.com");
	GetDlgItem(IDC_EDSUBJECT)->SetWindowText("website.rar");
	GetDlgItem(IDC_EDATT)->SetWindowText("C:\\Users\\username\\Desktop\\website.rar");
	GetDlgItem(IDC_EDBODY)->SetWindowText("");
	return TRUE; // return TRUE unless you set the focus to a control
}

运行后点击“发送”按钮，打开163邮箱：
