Hello.

I am trying to set a timeout value smaller than the default 30
seconds, without any success. MSDN does not mention this bug (http://
support.microsoft.com/kb/176420) in IE 7 (I'm using IE7 on XP).

I tried to set several flags, as in the following lines:

DWORD var = 4000L; // millisec
int b = InternetSetOption(fSession, INTERNET_OPTION_CONNECT_TIMEOUT,
(void *)&var, sizeof(var));
b = InternetSetOption(fSession, INTERNET_OPTION_DATA_RECEIVE_TIMEOUT,
(void *)&var, sizeof(var));
b = InternetSetOption(fSession, INTERNET_OPTION_DATA_SEND_TIMEOUT,
(void *)&var, sizeof(var));
b = InternetSetOption(fSession, INTERNET_OPTION_SEND_TIMEOUT, (void
*)&var, sizeof(var));
b = InternetSetOption(fSession, INTERNET_OPTION_RECEIVE_TIMEOUT, (void
*)&var, sizeof(var));
var = 4; // Retries
b = InternetSetOption(fSession, INTERNET_OPTION_CONNECT_RETRIES, (void
*)&var, sizeof(var));

Does anybody know anything more on this topic ?

Thank you.

Hi!

I have also been running into this problem.
We use WinInet.dll in a VBA project in Access, and we want to take the
connection timeout down to i.e. 5 seconds, so the application would not wait
for 50 seconds every time the web-server does not respond.

We make a HTTP-Request:
hOpen = InternetOpen(scUserAgent, INTERNET_OPEN_TYPE_PRECONFIG,
vbNullString, vbNullString, 0)
hOpenUrl = InternetOpenUrl(hOpen, url, vbNullString, 0,
INTERNET_FLAG_RELOAD, 0)

We are using Internet Explorer 6 SP2, does anyone know if the bug is
resolved or not? The Kb176420 just tell us that its a bug in IE 6 sp1...

We cant do it because, Access. Access is not multi threaded... So we have to
do it synchronous.

We are doint big data-transfer-jobs, with oracle, sqlserver and some http.
And if the webserver does not respond the application will wait i.e. 1000
http-requests * 50 seconds timeout ~ 14 hours... not good at all. would be
better if we could force the application to just wait a few seconds (~1
hour...).

Do you know where we can find if its still a bug in IE6 sp2 or IE7?...
Thanks!

I see. But I believe, there is still a solution. For example, to create a
DLL that will wrap all HTTP communications (in sync or async Wininet mode,
it does not matter) and exports functions that will be used in Access.
Anyway, I will direct your problem to WNDP team, they will let us know more
information concerning this issue.

Sam,

Here is what I recieved from WNDP team,

I'm sorry for the delay but this ongoing project we're on should be worth
it.

I've done some more digging around this. I did not reproduce the issue as
reported by the customer.

I verified 2 of the mentioned timeout options (CONNECT_TIMEOUT and
RECEIVE_TIMEOUT) and:

- when setting the new timeout values globally, they are properly
applied to subsequent created objects (session, connection, request
respectively). Note that the object created before changing the global
timeout still have the default timeout set.

- when overwriting the timeout for a given object, the new value
was properly picked up and by its derived objects as well

At this point, the way to go should be to investigate how exactly the
customer is calling the API (particularly how the newly set timeouts values
are exercised) but the issue is not reproducible currently on my IE7
binaries.

Hello,

I have read your problem which looks like mine. However, the context
is a bit different. My project is about a Java J2EE application under
IE 6.
We are using asynchronous http transfers throught the ActiveX Object
"Microsoft.XMLHTTP" (client side call with javascript). One of these
call takes a long time ( ~80 min ) because of the million datas to
insert into the Oracle Database. After ~60 min of activity, the state
of the ActiveX Object switch from 3 to 4 (complete state) with a "12
002" http status code. On the other hand, the server proccess is still
running and still inserting datas. I concluded this is about some
client (IE) bad configuration.

After searching information, i found that "12002" is a WinInet error
code. One solution could be to set a higher value for the Time Out
parameter. I found the "InternetSetOption" function but i have no idea
how to use it with Java or Javascript.

I have also tryied to modify a key in the windows registry
(ReceiveTimeout key in HKEY_CURRENT_USER\Software\Microsoft\Windows
\CurrentVersion\Internet Settings\) and set the parameter to a new
higher value with no effect on IE 6. (I found that information on
microsoft websites).
