RasApi error

[Kannan Ramanathan]

Hi all, I have a custom installer application for my driver. During the installation, it also creates a dialup entry. This works fine in WinXP and Win2K. But in Win98SE, the call RasSetEntryProperties() always returns fails, with an error code of 0x6f8. I tried finding what this error code means, but to no avail. The function RasGetErrorString(), when passed this error code, fails with an error code of 87. I am stuck here. Any ideas or suggestions on this problem is really appreciated.

Please remove [nospam] from my email ID for replying. I dont know why, but the forums is not allowing me to modify my msg anymore; says "You are not authorised to modify/delete". I guess, because of the email IDs mismatch, this error is coming. --------- Kannan Ramanathan kannan.ramanathan@st.com

I know number 87 - it's ERROR_INVALID_PARAMETER. I think error 0x6f8 (decimal 1784) should be interpreted as a Windows error code. Looking it up in WinError.h gives

//
// MessageId: ERROR_INVALID_USER_BUFFER
//
// MessageText:
//
// The supplied user buffer is not valid for the requested operation.
//
#define ERROR_INVALID_USER_BUFFER 1784L

As for why this should happen: I don't know. Are you trying to pass a phonebook name? Windows 98 does not support multiple phonebooks - you must pass NULL for the first parameter.

Thanks Mike. I am passing NULL for the first parameter. The problem is, this call succeeds to create the dialup entry randomly. And, the remaining times, it returns this 0x6f8. Here is my code segment.. RASENTRY RasEntry; memset(&RasEntry,0,sizeof(RASENTRY)); RasEntry.dwSize = sizeof(RASENTRY); DWORD dwfOptions = RASEO_RemoteDefaultGateway | RASEO_DisableLcpExtensions | RASEO_ModemLights; RasEntry.dwfNetProtocols = RASNP_Ip; RasEntry.dwFramingProtocol = RASFP_Ppp; strcpy (RasEntry.szLocalPhoneNumber,CalledParty); strcpy (RasEntry.szDeviceType,RASDT_Isdn); strcpy (RasEntry.szDeviceName,DeviceName); RasEntry.dwfOptions = dwfOptions; dwError = RasSetEntryProperties( NULL, PvcName, &RasEntry,sizeof(RASENTRY), NULL,0 );
