(MFC) How to Download Messages in MessageSet One at a TimeIf a message set contains a huge number of emails, it's NOT a good idea to try to download all at once into an email bundle using a method such as FetchBundle. It's better to interate over the message numbers in the set to download one by one.
#include <CkImap.h> #include <CkMessageSet.h> #include <CkEmail.h> void ChilkatSample(void) { CkString strOut; // This example requires the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. // This example copies an email from one mailbox to another. CkImap imap; // Connect using TLS. imap.put_Ssl(true); imap.put_Port(993); bool success = imap.Connect("imap.example.com"); if (success != true) { strOut.append(imap.lastErrorText()); strOut.append("\r\n"); SetDlgItemText(IDC_EDIT1,strOut.getUnicode()); return; } // Authenticate success = imap.Login("email_account_login","email_account_password"); if (success != true) { strOut.append(imap.lastErrorText()); strOut.append("\r\n"); SetDlgItemText(IDC_EDIT1,strOut.getUnicode()); return; } // Select an IMAP mailbox success = imap.SelectMailbox("Inbox"); if (success != true) { strOut.append(imap.lastErrorText()); strOut.append("\r\n"); SetDlgItemText(IDC_EDIT1,strOut.getUnicode()); return; } // Search for messages having "Test email" in the subject. bool fetchUids = true; CkMessageSet *messageSet = imap.Search("ALL",fetchUids); if (imap.get_LastMethodSuccess() != true) { strOut.append(imap.lastErrorText()); strOut.append("\r\n"); SetDlgItemText(IDC_EDIT1,strOut.getUnicode()); return; } strOut.append("Number of messages = "); strOut.appendInt(messageSet->get_Count()); strOut.append("\r\n"); int i = 0; while (i < messageSet->get_Count()) { CkEmail *email = imap.FetchSingle(messageSet->GetId(i),fetchUids); if (imap.get_LastMethodSuccess() != true) { strOut.append(imap.lastErrorText()); strOut.append("\r\n"); delete messageSet; SetDlgItemText(IDC_EDIT1,strOut.getUnicode()); return; } strOut.append(email->ck_from()); strOut.append("; "); strOut.append(email->subject()); strOut.append("\r\n"); delete email; i = i + 1; } delete messageSet; strOut.append("OK"); strOut.append("\r\n"); SetDlgItemText(IDC_EDIT1,strOut.getUnicode()); } |
