为什么RasDial函数总是返回668(ERROR_NO_CONNECT)错误呢?

[cobain]

参数真的没错呀,用window的拨号也能拨上呀

[u2m]

TCHAR lpszISP[256];
GetDlgItemText(IDC_EDIT_TELE,lpszISP,255);

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

lstrcpy(RasDialParams.szEntryName, _T(""));
lstrcpy(RasDialParams.szPhoneNumber, lpszISP);
lstrcpy(RasDialParams.szCallbackNumber, _T(""));
GetDlgItemText(IDC_EDIT_USER,RasDialParams.szUserName,UNLEN);
GetDlgItemText(IDC_EDIT_PASS,RasDialParams.szPassword, PWLEN);

hRasConn = NULL;
DWORD dwRet = RasDial(NULL, NULL, &RasDialParams, 0L, (RASDIALFUNC)RasDialFunc, &hRasConn);
你肯定参数没有完全正确

TCHAR lpszISP[256];
GetDlgItemText(IDC_EDIT_TELE,lpszISP,255);

hRasConn 必须先置为NULL。
