void TTools::GetSystemAllPort(TStringList * pList) { HKEY hKey; DWORD result; TCHAR valueName[255]; TCHAR data[255]; DWORD valueNameSize,dataSize; DWORD i; result = RegOpenKeyEx(HKEY_LOCAL_MACHINE, "Hardware\\DeviceMap\\SerialComm", NULL, KEY_READ, &hKey);//读取注册表串口信息 if(ERROR_SUCCESS == result) { for(i=0;i<256 ;i++) { valueNameSize = dataSize = sizeof(valueName) / sizeof(TCHAR); result = RegEnumValue(hKey, i, valueName, &valueNameSize, NULL, NULL, (LPBYTE)data, &dataSize); if(ERROR_NO_MORE_ITEMS == result ) { break; } else { pList->Add(data); } } } else { ::MessageBox(0,"PORT ERROR!","Error",0); } RegCloseKey(hKey); }

void TTools::GetSystemAllPort(TStringList * pList)
{
    HKEY hKey;
    DWORD result;
    TCHAR valueName[255];
    TCHAR data[255];
    DWORD valueNameSize,dataSize;
    DWORD i;
    result = RegOpenKeyEx(HKEY_LOCAL_MACHINE, "Hardware\\DeviceMap\\SerialComm", 
             NULL, KEY_READ, &hKey);//读取注册表串口信息
    if(ERROR_SUCCESS == result)
    {
        for(i=0;i<256 ;i++)
        {
            valueNameSize = dataSize = sizeof(valueName) / sizeof(TCHAR);
            result = RegEnumValue(hKey, i, valueName, &valueNameSize, NULL, NULL, 
                     (LPBYTE)data, &dataSize);
            if(ERROR_NO_MORE_ITEMS == result )
            {
                break;
            }
            else
            {
               pList->Add(data);
            }
        }
    }
    else
    {
        ::MessageBox(0,"PORT ERROR!","Error",0);
    }
    RegCloseKey(hKey);
}

代码中的pList  我自己用的是vector<string>pList;
