RasEnumEntries

[Jump_Around]

DWORD dwCb = sizeof(RASENTRYNAME);
DWORD dwErr = ERROR_SUCCESS;
DWORD dwRetries = 5;
DWORD dwEntries = 0;
RASENTRYNAME lpRasEntryName[20];

lpRasEntryName[0].dwSize = sizeof(RASENTRYNAME);


RasEnumEntries(NULL,NULL,lpRasEntryName,&dwCb,&dwEntries);

This is the code. the problem is that RasEnumEntries returns 610 which is ERROR_BUFFER_INVALID. What is wrong?

Please help me, please

LPRASENTRYNAME lpRasEntryName = NULL;
DWORD nRet;
DWORD cb;
DWORD cEntries;
lpRasEntryName = (LPRASENTRYNAME)GlobalAlloc(GPTR, sizeof(RASENTRYNAME));
lpRasEntryName->dwSize = sizeof(RASENTRYNAME);
if ((nRet = RasEnumEntries(NULL, NULL, lpRasEntryName, &cb, &cEntries))
== ERROR_BUFFER_TOO_SMALL)
{
lpRasEntryName = (LPRASENTRYNAME)GlobalAlloc(GPTR, cb);
lpRasEntryName->dwSize = sizeof(RASENTRYNAME);
}

// Calling RasEnumEntries to enumerate the phone-book entries

nRet = RasEnumEntries(NULL, NULL, lpRasEntryName, &cb, &cEntries);


Make sure add GlobalFree() and more error checking.

Well I copied the code to VisualC++ on Windows 2000 (at home) and works fine. At work (win 98) using Builder C++ still gives the error 610.

Any suggestions?

Yea don't support win98 ;) but seriously...hmm can't boot to win98 currently kinda have a messed up boot loader currently, so can't cross check it, but I'd advise checking IDE/help - MSDn help (msdn.microsoft.com) for rasenum, could be you need to install the unicode layer for win98...

Thanx Mick for quick advices, I really appreciate that. This is whaty I found.

Error 610- The buffer is invalid

Go into My computer > control panel > modems.
Go into properties of modem > Check port speed is set correctly.
If that did not work go into control panel > modems > remove modem > restart computer and then re-install modem.

I think my modem is not installed correctly, well I will check it tommorow and will let you know.

Take care :cool:

Ok, no prob, like I posted (win2000) which I only have at home for my dev env..will work fine...I've got no way to verify win98, wish I did or I could tell you...or at least give you some hint, but if you figure it out at (work) win98, then post your workaround/resolution here so some future person won't have do ask your question :)

I am not happy because I got still error 610 even when I use your piece of code. What's going on. Please help

I think it has to do with microsoft's bad habit of using #ifdef:s inside structure definitions for handling different O/S.

Try this:

#include <windows.h>
#define WINVER 0x400
#include <ras.h>
