Hi,

This is my code:



private TAPI3Lib.TAPIClass m_tapi=null;

private TAPI3Lib.ITAddress m_address=null;

private TAPI3Lib.ITBasicCallControl m_call=null;

ITMediaPlayback pMediaPlayback;

//....

private bool SelectTerminal()

{

try

{

ITTerminal pFileTerm=null;

ITTerminalSupport pTermSup=null;

pTermSup=(ITTerminalSupport)m_address;

pFileTerm=pTermSup.CreateTerminal(TapiConstants.CLSID_String_FilePlaybackTerminal, TapiConstants.TAPIMEDIATYPE_AUDIO,TERMINAL_DIRECTION.TD_CAPTURE);

if(pFileTerm==null)

MessageBox.Show("terminal is null");

pMediaPlayback=null;

pMediaPlayback=(ITMediaPlayback)pFileTerm;

object[] s=null;

if(m_strFileName.Length<1)

s=new string[]{"c:\\2.wav"};

else

s=new string[]{m_strFileName};

pMediaPlayback.PlayList=s;

ITCallInfo ci=(ITCallInfo)m_call;

ITBasicCallControl2 cc2=(ITBasicCallControl2)ci;

cc2.SelectTerminalOnCall(pFileTerm);

m_control=(ITMediaControl)pFileTerm;

}

catch(Exception ex)

{

MessageBox.Show(ex.Message);

}

return true;

}

//....

private void OnConnect()

{

m_control.Start();

}

The code gives me an Exception on this line:
pMediaPlayback.PlayList = s;
the exception is: Value does not fall within the expected range
What's that?What should I do?
