谢欣伦 - 化繁为简系列原创教程 - 通信专题 - 蓝牙设备查找类CxBthRadio & CxBthRadioFind

　　这是一个精练的蓝牙设备查找类，类名、函数名和变量名均采用匈牙利命名法。小写的x代表我的姓氏首字母（谢欣伦），个人习惯而已，如有雷同，纯属巧合。

CxBthRadioFind的使用如下：

void CUsbScannerDlg::OnBtnLocalBth() 

{

    // TODO: Add your control notification handler code here

    m_list1.ResetContent();

    

    BTH_DEV_INFO bdi = {0};

    CString str;

    CxBthRadioFind finder;

    BOOL bRet = finder.FindRadio();

    while (bRet)

    {

        finder.GetDeviceInfo(&bdi);

        m_list1.AddString(bdi.szName);

        m_list1.AddString(bdi.szMacAddr);

        

        str.Format(_T("Class of Device : 0x%08x"), bdi.ulClassofDevice);

        m_list1.AddString(str);



        m_list1.AddString("");

        m_list1.AddString("-->Next<--");

        bRet = finder.FindNextRadio();

    }

    finder.FindRadioClose();

}

CxBthRadio的使用如下：

void CUsbScannerDlg::OnBtnCurRemoteBthDev() 

{

    // TODO: Add your control notification handler code here

    m_list1.ResetContent();



    BTH_DEV_INFO bdi = {0};

    BOOL bRetLocalFind, bRetRemoteFind;

    CString str;

    CxBthRadioFind local_bth_find;

    CxBthRadio local_bth;



    bRetLocalFind = local_bth_find.FindRadio(FALSE);

    while (bRetLocalFind)

    {

        local_bth.Attach(local_bth_find.GetRadioHandle());



        bRetRemoteFind = local_bth.FindRemoteDevice(FALSE);

        while (bRetRemoteFind)

        {

            local_bth.GetRemoteDeviceInfo(&bdi);

            m_list1.AddString(bdi.szName);

            m_list1.AddString(bdi.szMacAddr);

            

            str.Format(_T("Class of Device : 0x%08x"), bdi.ulClassofDevice);

            m_list1.AddString(str);

            

            m_list1.AddString("");

            m_list1.AddString("-->Next<--");

            bRetRemoteFind = local_bth.FindNextRemoteDevice();

        }

        local_bth.FindRemoteDeviceClose();



        local_bth_find.CloseRadioHandle();



        bRetLocalFind = local_bth_find.FindNextRadio(FALSE);

    }

    local_bth_find.FindRadioClose();

}

　　精练的代码不需要过多解释，你们懂的。To be continued...
