这是一个软电话系统的签入部分

void CGuoTsapiDlg::OnButtonLogin()
{   
    m_TSAPICONNECTORCTRL1.SetAmsServerIP("192.168.0.126");
    m_TSAPICONNECTORCTRL1.SetAgentID(m_AGENTID);
    m_TSAPICONNECTORCTRL1.SetTsServerLinks("AVAYA#S8300#CSTA#VMAES52,ctiuser,Ctiuser@1");
    m_TSAPICONNECTORCTRL1.SetAmsAgentType(0);
    m_TSAPICONNECTORCTRL1.SetDeviceID(m_DEVICEID);
    m_TSAPICONNECTORCTRL1.SetPassword(" ");
    m_TSAPICONNECTORCTRL1.SetAmsSkills(" ");
    m_TSAPICONNECTORCTRL1.SetCallCount(0);
    m_TSAPICONNECTORCTRL1.SetCalledNumber(" ");
    m_TSAPICONNECTORCTRL1.SetCallingNumber(" ");
    //m_TSAPICONNECTORCTRL1.SetErrorMessage(m_TSAPICONNECTORCTRL1.GetErrorMessage());
    int ret = m_TSAPICONNECTORCTRL1.AgentLogin(1,0);
    if(ret == 0)
    {
        // 成功
        AfxMessageBox("成功");
    }else
    {
        // 失败
        AfxMessageBox(m_TSAPICONNECTORCTRL1.GetErrorMessage());

    }

   
    // TODO: Add your control notification handler code here
}
在做签入操作时，控件报错，坐席工号无效
AgentID和m_AGENTID都是CString

哪位大哥帮小弟讲讲，谢谢
