wxWidgets获取系统串口号

jie.lee posted @ 2010年6月05日 01:17 in 笔记 with tags wxWidgets , 5621 阅读

windows系统下获取存在的串口号，主要是读注册表相关键值。

void xxx::GetSerialPort()
{
    wxRegKey *m_pKey = new wxRegKey(_T("HKEY_LOCAL_MACHINE\\HARDWARE\\DEVICEMAP\\SERIALCOMM"));
    wxString strTemp;

    long l;
    bool bCont;
    wxString str;
    wxString strValue;
    Choice_com->Clear();

    bCont = m_pKey->GetFirstValue(str, l);
    while ( bCont )
    {
        m_pKey->QueryValue(str, strValue);
        Choice_com->Append(strValue);
        bCont = m_pKey->GetNextValue(str, l);
    }
    Choice_com->SetSelection(0);
    delete m_pKey;
}
