Titolo: IE7 wininet.dll bug

[Giorgio]

I have a lot of programs that are using the wininet.dll (InternetReadFile,
ecc.).
With IE 5.0 and IE 6.0 on WinXP sp2 there aren't problems.
With IE 7.0 the programs DON'T WORK, the InternetReadFile() return 0 and the
download stop.

My question is: Microsoft is working about this problem ?

Thanks

Insert GetLastError after InternetReadFile and post the error code here.
Hopefully it will help to find out the problem.
BOOL bResult = InternetReadFile(...);
DWORD dwError;
if (bResult)
{
dwError = ERROR_SUCCESS;
}
else
{
dwError = GetLastError();
}

The problem is the default of INTERNET_OPTION_RECEIVE_TIMEOUT, it was 0 (
infinitely) for IE 6.0 (and before). The default of IE 7.0 is 30 (sec) so if
your task on IIS is longer than 30 seconds the timeout stops the connection.
Fortunately, I have the source code of the programs that use the Wininet.dll
and I have corrected the code.

Thank

Could you please write a c# sample of declaration and use of the
InternetSetOption API with INTERNET_OPTION_RECEIVE_TIMEOUT flag ?

thanks

To set the INTERNET_OPTION_RECEIVE_TIMEOUT to 0 (like the default of IE6), I
use this code (in Visual FoxPro).
* === Start
m.dwTimeoutSecs = 0
llRetVal=InternetSetOption(THIS.hIPSession,;
INTERNET_OPTION_RECEIVE_TIMEOUT, ;
@dwTimeoutSecs, 4 )
* === End

I hope that is enough
