VC++ 的POP接收邮件源代码是什么样的？

安装JMail45。在安装目录下面会有jmail.dll，考到自己的项目目录下面，

然后在项目中加入:import "jmail.dll"，收邮件的简要代码如下：

try

{

jmail::IPOP3Ptr pPOP3("JMail.POP3");

jmail::IMessagesPtr pMessages;

// 超时 30S

pPOP3-Timeout = 30;

// 连接邮件服务器

pPOP3-Connect((LPCTSTR)m_strUserid,

(LPCTSTR)m_strPassword,

(LPCTSTR)m_strMailServer,

110);

pMessages = pPOP3-Messages;

// 已下载的邮件的实际个数(因为第0个ITEM是未用的，所以-1)

long lCount = pMessages-Count - 1;

if(lCount == 0)

AfxMessageBox("信箱为空");

else

{

jmail::IMessagePtr pMessage;

// 遍历每封信

for(long i = 1; i = lCount; i++)

{

pMessage = pMessages-Item[i];

_bstr_t bstrFrom = pMessage-From;

_bstr_t bstrSubject = pMessage-Subject;

_bstr_t bstrBody = pMessage-Body;

COleDateTime oleDate = pMessage-Date;

int nListItem = m_ctlMessagesList.InsertItem(i, (const char*)bstrFrom);

m_ctlMessagesList.SetItem(nListItem, 1, LVIF_TEXT, (const char*)bstrSubject, 0, 0, 0, NULL);

m_ctlMessagesList.SetItem(nListItem, 2, LVIF_TEXT, (const char*)oleDate.Format("%Y-%m-%d"), 0, 0, 0, NULL);

m_strBodyArray.Add((const char*)bstrBody);

pMessage.Release();

}

}

// 断开连接

pPOP3-Disconnect();

}

catch(_com_error e)

{

CString strErr;

strErr.Format("错误信息：%s\r\n错误描述：%s", (LPCTSTR)e.ErrorMessage(), (LPCTSTR)e.Description());

AfxMessageBox(strErr);

}
