谢欣伦 - OpenDev原创教程 - 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 = {};
    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 = {};
    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...
