I compiled the sample LevelOne app using MSVC 2008 on both Windows 7 and Windows 8 OS and if I don't use Protocol 5.0 or 5.1 and request GBPUSD.FXCM as a watch I get the correct data and fields as requested. If I use Protocol 5.0 or 5.1 I get an invalid symbol message. Is there something I am missing here...see attached image...thanks in advance

the simple solution to this problem was to add a TrimRight() to the symbol string before formatting the command...eg:

CString csCommand(m_csUserData);
csCommand.MakeUpper();
if (m_csUserData == csCommand)
{
// add this line
//
m_csUserData.TrimRight();

csCommand.Format("w%s\r\n", m_csUserData);
m_IQConnectSocket.Send(csCommand, csCommand.GetLength());
}
