WM_RASDIALEVENTdoesn't seem to be working

Question

I am having trouble getting the callback interface for the RasDial function to work. My Dialog box calls the RasDial function from a Button Click Event handler, as follows:

hRasConn = NULL;

memset (&m_RasDialParams, 0, sizeof (RASDIALPARAMS)); 

m_RasDialParams.dwSize = sizeof (RASDIALPARAMS);

m_RasDialParams.szPhoneNumber[0] = TEXT('\0'); // use the phone number from the Ras Named Entry

m_RasDialParams.szCallbackNumber[0] = TEXT('\0');

StringCbCopy(m_RasDialParams.szEntryName,sizeof(m_RasDialParams.szEntryName),m_szRasEntryName);

StringCbCopy(m_RasDialParams.szUserName,sizeof(m_RasDialParams.szUserName),m_szUserName); //This is optional

StringCbCopy(m_RasDialParams.szPassword,sizeof(m_RasDialParams.szPassword),m_szPassword); //This is optional

StringCbCopy(m_RasDialParams.szDomain,sizeof(m_RasDialParams.szDomain),m_szDomain); //This is optional

dialStatus = RasDial(NULL,NULL, &m_RasDialParams,0xFFFFFFFF, g_hwndModemDlg, &hRasConn);

where dialStatus is a local variable in the function that calls RasDial:

DWORD dialStatus = 0;

where the mRasDialParams is set up as a private member of the Dialog:

RASDIALPARAMS m_RasDialParams;

and g_hwndModemDlg is a global variableHWND g_hwndModemDlg;

 that is set just before the RasDial function is called.

g_hwndModemDlg = this->m_hWnd;

 and hRasConn is a local variable defined in the function calling RasDial

HRASCONN hRasConn;

I have the callback function defined in the DialogBox Class definition as:

afx_msg LRESULT OnRasDialEvent(WPARAM wp, LPARAM lp);

and I am hooking in to the WM_RASDIALEVENT in this MFC Dialog with

BEGIN_MESSAGE_MAP(CModemDlg, CDialog)

ON_BN_CLICKED(IDC_DIAL_BTN, &CModemDlg::OnBnClickedDialBtn)

ON_BN_CLICKED(IDC_ENDCONN_BTN, &CModemDlg::OnBnClickedEndconnBtn)

ON_MESSAGE ( WM_RASDIALEVENT , OnRasDialEvent )

END_MESSAGE_MAP()

 

The RasDial Function returns 0 and I can get the dialing status using the  RasGetConnectStatus function, but my OnRasDialEvent Function never gets called.

If anyone can tell me what I am doing wrong I would really appreciate it.
