After I do a RasDial() function, RasGetConnectStatus() always returns a 632 error code. Here's what I have: I've made it as simple as possible.

C++

RASDIALPARAMS pParams;
HRASCONN      hRas;
DWORD         dwRetVal;
DWORD         dw_ret;
RASCONNSTATUS status;

hRasInstance = LoadLibrary("RASAPI32.DLL");
fRasDial = (pRasDial)GetProcAddress(hRasInstance, "RasDialA");
fRasGetErrorString = (pRasGetErrorString)GetProcAddress(hRasInstance, "RasGetErrorStringA");
fRasEnumConnections = (pRasEnumConnections)GetProcAddress(hRasInstance, "RasEnumConnectionsA");
fRasHangUp = (pRasHangUp)GetProcAddress(hRasInstance, "RasHangUpA");
fRasGetConnectStatus = (pRasGetConnectStatus)GetProcAddress(hRasInstance, "RasGetConnectStatusA")

pParams.dwSize = sizeof(RASDIALPARAMS); // I've tried 816, 1052 and 1060

hRas = 0;
dwRetVal = fRasDial(NULL, NULL, &pParams, 1, RasCallback, &hRas);

// dwRetVal is always a 0.

dw_ret = fRasGetConnectStatus(hRas, &status);

if(dw_ret)
{
  // Display the error. Is always a 632. 
}

Solution 3

I'm doing this:

status.dwSize = sizeof(RASCONNSTATUS); // status.dwSize turns out to be 288

dw_ret = fRasGetConnectStatus(hRas, &status);

if(dw_ret) // dw_ret is a 6
{
fRasGetErrorString(dw_ret, buff, sizeof(buff));
sprintf(szString, "RAS: %s, Error: %d", buff, dw_ret);
ShowMessage(szString);
}
