1 利用Spy++获取窗口和某一控件的Class Name, Title Name;  
  
2 利用Class Name, Title Name获取handle然后发送消息;  
代码如下：

void CFindWindowTestDlg::OnBnClickedFindSkypeBtn()
    {
       
        // TODO: Add your control notification handler code here
        HWND m_pHwnd = ::FindWindow(_T("TConversationForm"), _T("Jacky"));
        ASSERT(m_pHwnd != NULL);
        HWND m_pHwndTChatEntryControl = ::FindWindowEx(m_pHwnd, NULL, _T("TChatEntryControl"), NULL);
        ASSERT(m_pHwndTChatEntryControl != NULL);
        HWND m_pHwndTTChatRichEdit = ::FindWindowEx(m_pHwndTChatEntryControl, NULL, _T("TChatRichEdit"), NULL);
        ASSERT(m_pHwndTTChatRichEdit != NULL);
    
        if (m_pHwndTTChatRichEdit != NULL)
        {
       
            for (int i =0; i<20; i++)
            {
       
                ::PostMessage(m_pHwndTTChatRichEdit, WM_CHAR, 'T', NULL);
                ::PostMessage(m_pHwndTTChatRichEdit, WM_CHAR, 'e', NULL);
                ::PostMessage(m_pHwndTTChatRichEdit, WM_CHAR, 's', NULL);
                ::PostMessage(m_pHwndTTChatRichEdit, WM_CHAR, 't', NULL);
                ::PostMessage(m_pHwndTTChatRichEdit, WM_CHAR, ' ', NULL);
                ::PostMessage(m_pHwndTTChatRichEdit, WM_CHAR, 'M', NULL);
                ::PostMessage(m_pHwndTTChatRichEdit, WM_CHAR, 'e', NULL);
                ::PostMessage(m_pHwndTTChatRichEdit, WM_CHAR, 's', NULL);
                ::PostMessage(m_pHwndTTChatRichEdit, WM_CHAR, 's', NULL);

                Sleep(200);
            }
        }
