Re: WinInet : Error 12031
Try to call InternetGetLastResponseInfo, it may output something helpful.
EDIT: ERROR_INTERNET_CONNECTION_RESET should mean that the connection was lost. Were you downloading something in the meantime? Do you get this error every time? If you connect with the browser do you have any problem?
Re: WinInet : Error 12031
Now, it re-run correctly :S
So, i can't get any error to analyse it ?
While it didn't ran, internet was ok, i successfully surf on web :(
so what's wrong ?
Re: WinInet : Error 12031
Re: WinInet : Error 12031
Re: WinInet : Error 12031
The problem seem being due to AtiveSync,
anyone knows something about it ?
Re: WinInet : Error 12031
are you running it on PC or mobile device? because ActiveSync is in a game only if you are on PDA
besides, InternetOpenUrl just fails sometimes for unknown reason, InternetOpen is more reliable
Re: WinInet : Error 12031
I work on a PDA using WinCE 5.0
but, even disconnected from PC, the embedded application continue to get error 12031 on InternetOpenURL
Re: WinInet : Error 12031
Writing InternetOpen is more reliable , you seems telling InternetOpen might be used instead of InternetOpenUrl.
But I also use it,
here is my code (for eMbedded Visual C++)
Code:
CStatic * txt = (CStatic *) GetDlgItem(IDC_STATIC1),
* txtErrCode = (CStatic *) GetDlgItem(IDC_STATIC_ERRCODE);
CString sErr;
DWORD flags;
HINTERNET hInternetSession, hHttpSession;
flags = INTERNET_CONNECTION_OFFLINE;
BOOL connected = InternetGetConnectedState(&flags, 0);
if (connected)
{
connected = FALSE;
hInternetSession = InternetOpen (USER_AGENT, INTERNET_OPEN_TYPE_PRECONFIG, NULL, NULL, NULL) ;
if (hInternetSession)
{
hHttpSession = InternetOpenUrl( hInternetSession, _T("http://www.google.com"), NULL, 0, INTERNET_FLAG_NO_CACHE_WRITE | INTERNET_FLAG_NO_UI | INTERNET_FLAG_PRAGMA_NOCACHE | INTERNET_FLAG_RELOAD| INTERNET_FLAG_SECURE | INTERNET_FLAG_IGNORE_CERT_CN_INVALID | INTERNET_FLAG_IGNORE_CERT_DATE_INVALID, 0 ) ;
connected = hHttpSession != NULL;
if (connected)
InternetCloseHandle( hHttpSession );
else
txt->SetWindowText(_T("Step 3 HS"));
InternetCloseHandle (hInternetSession) ;
}
else
txt->SetWindowText(_T("Step 2 HS"));
}
else
txt->SetWindowText(_T("Step 1 HS"));
sErr.Format(_T("%d"), GetLastError());
txtErrCode->SetWindowText(sErr);
Is it good ? or how modify it ?
Re: WinInet : Error 12031

Re: WinInet : Error 12031
Thanks for your help,
I'll follow your code.
Re: WinInet : Error 12031
Argh !
I won't see I need to write the protocole by myself.
It's an SSL connexion, it's not so easy like "GET /"
Re: WinInet : Error 12031
well, it is almost the same, you get it from InternetCrackUrl() and specify appropriate in InternetConnect()
Re: WinInet : Error 12031
I never write SSL request, do you know where i can found any information about this ?
"SSL request" on google is loosing me !
thanks.
Re: WinInet : Error 12031
why should you deal with it? WinInet does it already, so just specify correct flags (for HTTPS)
I've successfully communicated with such code to Web Service over https/SSL connections
Re: WinInet : Error 12031
Hi,
I'm trying many things to get it, but I failed,
here is my test code :
Code:
CString sErr;
m_edit1 = "";
// Open Internet session.
HINTERNET hSession = ::InternetOpen (USER_AGENT, PRE_CONFIG_INTERNET_ACCESS, NULL, NULL, NULL) ;
// Connect to www.microsoft.com.
HINTERNET hConnect = ::InternetConnect(hSession, _T("ssl.mywebsite.com"), 443, _T(""), _T(""), INTERNET_SERVICE_HTTP, 0,0) ;
// Request the file /MSDN/MSDNINFO/ from the server.
HINTERNET hHttpFile = ::HttpOpenRequest(hConnect,
_T("GET"),
_T("/index.php4?p=10&login=jb&password=test"),
HTTP_VERSION,
NULL,
0,
INTERNET_FLAG_DONT_CACHE,
0) ;
// Send the request.
BOOL bSendRequest = ::HttpSendRequest(hHttpFile, NULL, 0, 0, 0);
DWORD dwFileSize = 4096;
char buffer[4096+1];
m_edit1 = "";
DWORD dwBytesRead ;
BOOL bRead;
int i, nRead = 0;
do
{
nRead++;
bRead = ::InternetReadFile( hHttpFile,
buffer,
dwFileSize+1,
&dwBytesRead);
if ( (bRead) && (dwBytesRead>0) ){
for(i=0; i<dwBytesRead; i++){
if ( (buffer[i] != '\n') && (buffer[i] != '\r') ){
sErr.Format(_T("%c"), buffer[i]);
m_edit1 = m_edit1 + sErr;
}
else{
if (buffer[i] == '\n'){
m_edit1 = m_edit1 + "\r\n";
}
}
}
}
}while( (bRead == TRUE) && (dwBytesRead > 0) && (nRead < 10) );
// Close all of the Internet handles.
::InternetCloseHandle(hHttpFile);
::InternetCloseHandle(hConnect) ;
::InternetCloseHandle(hSession) ;
// Display the file in an edit control.
UpdateData(FALSE);
And I got :

Any Idea ?
Re: WinInet : Error 12031
Try to use the flag INTERNET_FLAG_SECURE with the flags used in the call to HttpOpenRequest:
Code:
HttpOpenRequest(hConnect, ... INTERNET_FLAG_DONT_CACHE|INTERNET_FLAG_SECURE, 0);
EDIT: btw, here's a kb from microsoft on this subject: http://support.microsoft.com/kb/168151
Re: WinInet : Error 12031
here is another sample:
http://www.codeproject.com/internet/...&select=953306
and yes, you have to specify INTERNET_FLAG_SECURE in HttpOpenRequest
