c++ 应用程序获取outlook联系人的详细步骤及代码

获取Outlook联系人的详细步骤及代码如下：

1. 引入Outlook头文件

#include <afxwin.h>
#include <afxdisp.h>
#include <atlbase.h>
#include <atlcom.h>
#include <atlctl.h>
#include <oleauto.h>
#include <msoutl.h>

2. 定义COleException异常类

class COleException : public CException
{
public:
    COleException(HRESULT hr);
    virtual ~COleException() throw();

    // Attributes
public:
    HRESULT m_hr;

    // Implementation
public:
    virtual BOOL GetErrorMessage(LPTSTR lpszError, UINT nMaxError,
        PUINT pnHelpContext = NULL);
};

3. 实现COleException异常类

COleException::COleException(HRESULT hr) : m_hr(hr)
{
}

COleException::~COleException() throw()
{
}

BOOL COleException::GetErrorMessage(LPTSTR lpszError, UINT nMaxError,
    PUINT pnHelpContext)
{
    CString str;
    str.Format(_T("0x%08x"), m_hr);
    lstrcpyn(lpszError, str, nMaxError);
    return TRUE;
}

4. 定义COutlookContacts类

class COutlookContacts
{
public:
    COutlookContacts();
    virtual ~COutlookContacts();

    // Operations
public:
    BOOL CreateDispatch(LPCTSTR lpszProgID);
    void CloseDispatch();

    COleException m_exception;
    _Application m_app;
    _NameSpace m_session;
    _Items m_items;
    _MailItem m_mailItem;

    // Implementation
protected:
    void ThrowException(HRESULT hr);
};

5. 实现COutlookContacts类

COutlookContacts::COutlookContacts()
{
}

COutlookContacts::~COutlookContacts()
{
    CloseDispatch();
}

BOOL COutlookContacts::CreateDispatch(LPCTSTR lpszProgID)
{
    COleException e;
    if (!m_app.CreateDispatch(lpszProgID, &e))
    {
        ThrowException(e.m_hr);
        return FALSE;
    }

    m_session.AttachDispatch(m_app.GetNamespace(_T("MAPI")));

    try
    {
        m_session.Logon(_T(""), _T(""), TRUE, TRUE);
        m_items.AttachDispatch(m_session.GetDefaultFolder(olFolderContacts)->GetItems(), TRUE);
    }
    catch (COleException* pEx)
    {
        ThrowException(pEx->m_hr);
        pEx->Delete();
        return FALSE;
    }

    return TRUE;
}

void COutlookContacts::CloseDispatch()
{
    m_items.ReleaseDispatch();
    m_session.ReleaseDispatch();
    m_app.ReleaseDispatch();
}

void COutlookContacts::ThrowException(HRESULT hr)
{
    m_exception.m_hr = hr;
    THROW(m_exception);
}

6. 使用COutlookContacts类获取联系人信息

COutlookContacts outlook;
if (outlook.CreateDispatch(_T("Outlook.Application")))
{
    int count = outlook.m_items.GetCount();
    for (int i = 1; i <= count; i++)
    {
        _ContactItem contactItem = outlook.m_items.GetItem(COleVariant((short)i));
        CString name = contactItem.GetFullName();
        CString email = contactItem.GetEmail1Address();
        // Do something with the name and email
    }
    outlook.CloseDispatch();
}
else
{
    AfxMessageBox(_T("Failed to create Outlook session."));
}

注意：需要在项目属性中的“C/C++” -> “预处理器” -> “预处理器定义”中添加“_ATL_APARTMENT_THREADED”宏定义。另外，需要在程序运行时保证Outlook已经启动。
