RasDial() howto

eusto

I'm trying to use RasDial to connect through a modem to a network my code:

RASDIALPARAMS rdParams;
rdParams.dwSize = sizeof(RASDIALPARAMS);
rdParams.szEntryName\[0\] = '\\0';
lstrcpy(rdParams.szPhoneNumber, strPhoneNr);
rdParams.szCallbackNumber\[0\] = '\\0';
lstrcpy( rdParams.szUserName, strUserNr);
lstrcpy( rdParams.szPassword, strPassword);    
rdParams.szDomain\[0\] = '\\0';

HRASCONN hRasConn = NULL;
dwRet = RasDial( NULL, NULL, &rdParams, NULL, NULL, &hRasConn );

The RasDial call results in a XP bluescreen. Anybody ever got this error? What should i check for? Thanks

Does this mean that RasDial() is not returning?

Yes, it is not returning. My whole computer dies. The fix for me is to use the phone book feature of windows:

RASDIALPARAMS rdParams;
rdParams.dwSize = sizeof(RASDIALPARAMS);

//set the szEntryName to an already defined connection 
lstrcpy(rdParams.szEntryName,strPredefinedConnectionName);
//not using these features because they're already defined in that connection
rdParams.szPhoneNumber\[0\] = 0;
rdParams.szPhoneNumber\[0\] = 0;
rdParams.szUserName\[0\] = 0;
rdParams.szPassword\[0\] = 0;
rdParams.szCallbackNumber\[0\] = '\\0';
rdParams.szDomain\[0\] = '\\0';

HRASCONN hRasConn = NULL;
dwRet = RasDial( NULL,
    "C:\\\\Documents and Settings\\\\"
        "All Users\\\\Application Data\\\\"
        "Microsoft\\\\Network\\\\Connections\\\\Pbk\\\\rasphone.pbk", //the system path to the phone book
        &rdParams, 
        NULL, 
        NULL, 
        &hRasConn 
        );

It's a bit frustrating that i can't use this to work with "on the fly" dialup connections. The windows blue screen really scares me :sigh:

So the only difference is the second argument? MSDN states that if this parameter is NULL, the function uses the current default phone-book file. The default phone-book file is the one selected by the user in the User Preferences property sheet of the Dial-Up Networking dialog box. Do you have this set up?

The difference is in the way i specify the connection to use. I'm telling RasDial to use the strPredefinedConnectionName (ex: a connection named MyDialup that appears in network connections) from the specified phone book. I've read that in MSDN also but i couldn't find the dialog for this setting. Do you think that the blue screen error is caused by the fact that my default user does not have a phonebook configured?

I would hope not. The BSOD is when Windows has gotten really angry and something totally unexpected has happened in some code. Telling Windows to use a file that does not exist should simply result in a normal "error" message box (i.e., failing gracefully). I'm sorry I do not have any better suggestions.
