VC++ 使用ShellExecute函数调用邮箱客户端发送邮件(可以带附件)

之前写过一篇博文，通过MAPI实现调用邮箱客户端发送邮件带附件，当时对ShellExecute研究不深，以为ShellExecute不能带附件，因为项目需求原因(MAPI只能调用Foxmail和Outlook邮箱客户端，无法调用网易邮箱大师)，不得不回头再次研究ShellExecute函数，最后发现ShellExecute可以完美调用Foxmail、网易邮箱大师、Outlook(单次发送只能添加一个附件)。因为我们安装完Foxmail、网易大师后，系统右键里发送到里有他们的快捷方式，所以就是在这里入手的，它们的快捷方式存放在系统路径下 C:\Users\Administrator\AppData\Roaming\Microsoft\Windows\SendTo (这是我的电脑上的位置，具体根据当前系统登录用户目录下找)

Foxmail：

int SharedByFoxmail()
{
TCHAR szPath[MAX_PATH] = {  };
SHGetSpecialFolderPath(NULL, szPath, CSIDL_SENDTO, FALSE);
CString strClient;
strClient.Format(L"%ls", szPath);
strClient += L"\\Foxmail.lnk";//拿到快捷方式的绝对路径

 CString strRecv = “example@.com”;//收件人
 CString FilePath = "\"C:\\Users\\Administrator\\Desktop\\123.txt\" \"C:\\Users\\Administrator\\Desktop\\image.png\"";//多个附件发送时 路径要用双引号括起来，路径之间用空格隔开

ShellExecute(NULL, L"open", strClient,FilePath, L"", SW_SHOW);

//填写收件人
HWND hWnd = NULL;
    int n = ;
    do
    {
        Sleep();
        hWnd = ::FindWindow(L"TFoxComposeForm.UnicodeClass", NULL);
        n--;
    } while (n && (hWnd == NULL || !::IsWindowVisible(hWnd)));

    if (hWnd == NULL)
    {
        return -;
    }

    HWND hChildWnd1 = NULL;
    HWND hChildWnd2 = NULL;
    HWND hChildWnd31 = NULL;
    HWND hChildWnd32 = NULL;
    HWND hChildWnd33 = NULL;
    if (hWnd != NULL)
    {
        ::SetForegroundWindow(hWnd);

        hChildWnd1 = ::FindWindowEx(hWnd, , L"TFoxComposeFrame.UnicodeClass", NULL);
        hChildWnd2 = ::FindWindowEx(hChildWnd1, , L"TLayoutManager", NULL);
        hChildWnd31 = ::FindWindowEx(hChildWnd2, , L"TFMZRichEdit.UnicodeClass", NULL);
        //抄送
        hChildWnd32 = ::FindWindowEx(hChildWnd2, hChildWnd31, L"TFMZRichEdit.UnicodeClass", NULL);
        if (hChildWnd32 != NULL)
        {
            DWORD SelfThreadId = GetCurrentThreadId();//获取本身的线程ID
            DWORD ForeThreadId = GetWindowThreadProcessId(hChildWnd32, NULL);//根据窗口句柄获取线程ID
            AttachThreadInput(ForeThreadId, SelfThreadId, true);//附加线程

            //            WCHAR* szTest = L"comor_86sssss163.com";
            //::SendMessage(hChildWnd32, WM_SETTEXT, 0, (LPARAM)strCC.GetBuffer(0));
            //strCC.ReleaseBuffer();
        }

        //收件人
        hChildWnd33 = ::FindWindowEx(hChildWnd2, hChildWnd32, L"TFMZRichEdit.UnicodeClass", NULL);
        if (hChildWnd33 != NULL)
        {
            DWORD SelfThreadId = GetCurrentThreadId();//获取本身的线程ID
            DWORD ForeThreadId = GetWindowThreadProcessId(hChildWnd33, NULL);//根据窗口句柄获取线程ID
            AttachThreadInput(ForeThreadId, SelfThreadId, true);//附加线程

            //            WCHAR* szTest = L"comor_86@163.com";
            ::SendMessage(hChildWnd33, WM_SETTEXT, , (LPARAM)strRecv.GetBuffer());
            strRecv.ReleaseBuffer();
        }
    }
return 0;
}
