Visual C++ Example

After you received the emails from email server to the local folder, we can use the following code to parse the email now. The following code demonstrates how to parse from, to, cc, subject, body text, attachments of specified EML file.

Code:

// The following example codes demonstrate parsing email (*.EML) file
// To get full sample projects, please download and install EAGetMail on your machine.
// To run it correctly, please change email server, user, password, folder, file name value to yours

#include "stdafx.h" 

#include "eagetmailobj.tlh" 
using namespace EAGetMailObjLib; 

void ParseEmail( LPCTSTR lpszFile ) 
{ 
    try 
    { 
        IMailPtr oMail = NULL; 
        oMail.CreateInstance("EAGetMailObj.Mail"); 
        oMail->LicenseCode = _T("TryIt"); 

        oMail->LoadFile( lpszFile, VARIANT_FALSE ); 

        // Parse email sender
        _tprintf(_T("From: %s\r\n"), (const TCHAR*)oMail->From->Address); 

        // Parse to recipient
        _variant_t varry = oMail->To; 
        SAFEARRAY *psa = varry.parray; 
        long i = 0, LBound = 0, UBound = 0; 
        SafeArrayGetLBound( psa, 1, &LBound ); 
        SafeArrayGetUBound( psa, 1, &UBound ); 
        for( i = LBound; i <= UBound; i++ ) 
        { 
            _variant_t vt; 
            SafeArrayGetElement( psa, &i, &vt ); 

            IMailAddressPtr pAddr; 
            vt.pdispVal->QueryInterface(__uuidof(IMailAddress), (void**)&pAddr); 
            _tprintf(_T("To: %s\r\n"), (const TCHAR*)pAddr->Address); 
        } 

        // Parse CC
        varry = oMail->Cc; 
        psa = varry.parray; 
        SafeArrayGetLBound( psa, 1, &LBound ); 
        SafeArrayGetUBound( psa, 1, &UBound ); 
        for( i = LBound; i <= UBound; i++ ) 
        { 
            _variant_t vt; 
            SafeArrayGetElement( psa, &i, &vt ); 

            IMailAddressPtr pAddr; 
            vt.pdispVal->QueryInterface(__uuidof(IMailAddress), (void**)&pAddr); 
            _tprintf(_T("Cc: %s\r\n"), (const TCHAR*)pAddr->Address); 
        } 

        // Parse email subject
        _tprintf(_T("Subject: %s\r\n"), (const TCHAR*)oMail->Subject); 

        // Parse email text body
        _tprintf(_T("TextBody: %s\r\n"), (const TCHAR*)oMail->TextBody); 

        // Parse email HTML body
        _tprintf(_T("HtmlBody: %s\r\n"), (const TCHAR*)oMail->HtmlBody); 

        // Parse attachment
        varry = oMail->Attachments; 
        psa = varry.parray; 
        SafeArrayGetLBound( psa, 1, &LBound ); 
        SafeArrayGetUBound( psa, 1, &UBound ); 
        for( i = LBound; i <= UBound; i++ ) 
        { 
            _variant_t vt; 
            SafeArrayGetElement( psa, &i, &vt ); 

            IAttachmentPtr pAtt; 
            vt.pdispVal->QueryInterface(__uuidof(IAttachment), (void**)&pAtt); 
            _tprintf(_T("Attachment: %s\r\n"), (const TCHAR*)pAtt->Name); 
        } 

    } 
    catch( _com_error &ep ) 
    { 
        _tprintf(_T("Error: %s\r\n"), (const TCHAR*)ep.Description()); 
    } 
} 

int _tmain(int argc, _TCHAR* argv[]) 
{ 
    // Initialize COM environment
    ::CoInitialize( NULL ); 

    ParseEmail(_T("c:\\my folder\\test.eml")); 

    return 0;
