如何程序去查看 电脑中已经连接的蓝牙设备的个数 急！！！！！！！！！！

[dns007]

需求如标题

另外 就是点击我的电脑 在光盘下面有个蓝牙图标（其它设备） 双击进去 会排列 已经搜索到的蓝牙设备的图标，我原想计算这个目录下图标的个数，但是不知道如何进到 我的电脑\\蓝牙（其它设备） 这个目录。

总之 我只要得到可连接蓝牙设备的个数即可以上，求解！！！

使用方法定义个CBlueTooth对象，如下所述：
顶一个CBlueTooth m_pBlueTooth = NULL; //初始化时候为NULL
if(NULL != m_pBlueTooth)
{
delete m_pBlueTooth;
m_pBlueTooth = NULL;
}
m_pBlueTooth = new CBlueTooth;
if(!m_pBlueTooth)
{
return FALSE;
}

BOOL bRet = m_pBlueTooth->Init(); // 初始化蓝牙设备

下面这个函数是扫描周边蓝牙设备，并把结果显示在ListBox中：
void CBTDEMODlg::OnScanBlueToothDevice()
{
// TODO: Add your control notification handler code here
ASSERT(m_pBlueTooth);
if(m_pBlueTooth->ScanDeviceInfo(NULL, GetSafeHwnd()))
{
CString strName(_T(""));
CString strValue(_T(""));
CString strText(_T(""));

m_list.ResetContent();

for(vector<BlueToothDeviceInfo>::const_iterator iter = m_pBlueTooth->vecBthDevInfo.begin(); iter != m_pBlueTooth->vecBthDevInfo.end(); iter++)
{
strName.Empty();
strName.Format(_T("%s"), iter->szName);
strValue.Empty();
strValue.Format(_T("%s"), m_pBlueTooth->FormatBlueToothAddress(iter->RemoteAddr));
strText.Empty();
strText.Format(_T("%s (%s)"), strName, strValue);

m_list.AddString(strText);
}
}
}

能否发一份到我的邮箱啊 [e-mail] 感谢了！

至于你的要求 我只要得到可连接蓝牙设备的个数即可
------------------------------------------------
这个更简单，扫描到数据以后，m_pBlueTooth->vecBthDevInfo.size()保存的就是蓝牙设备的个数

我是实在EVC下写的，你在其他平台上的话，可能要改一些，比如#pragma comment(lib,"ws2_lib"),你可能要修改成#pragma comment(lib,"ws2_32.lib")

OK,发给你，请注意查收。。。。。。。。。。

再请教下 我是在VS2008下 build 是不是要有些 头文件不可用啊 如下面这个错误
fatal error C1083: 无法打开包括文件:“mbctype.h”: No such file or directory

如果要转换的话 要改那些东西呢 ？

你有关于蓝牙连接的方式，我搜索到设备后进行连接的时候 手机会提示要输入PIN 但是这个PIN 是什么 ？
