Hello,

I have a problem with getting input stream from http site. I have
constructed wxURL, but it seams to hang on wxURL::GetInputStream(). Does
anyone else have such problem? If so is there any workaround for it?
Here is a sample code that I'm using:

wxURL url(__url);
if (url.IsOk())
{
wxInputStream* _in_stream;
_is_stream = url.GetInputStream(); // <-- Hangs here and
waits for something. :(
...
}


Using:
wx280 CVS
WinXP sp2
Code::Blocks
GCC

Regards,
Peter

how about ...

wxURL url(myURL);
if (url.GetError() != wxURL_NOERR)
{
return NULL ;
}
wxInputStream * pInput = url.GetInputStream() ;

what is the URL?

the problem is that the timeout for the connection with the server is
set by default to 10 minutes. Too long. It seems to be hanged but it's not.

You need to get access to the wxProtocol associated with the wxURL and
use SetTimeout with a reasonable value.

HTH,
Francesco

It doesn't make a difference because wxURL::IsOk() is defined as return
(GetError() == wxURL_NOERR). Also I have added else statement just to
see if there are no errors. If you want you can try this address:
http://redphoenix.sytes.net/test/test.txt

Thanks, I have setted it to 1 minute. The problem is that I CAN access
file with IE or FireFox, but I get time out with wxURL. Also another
thing is that I get empty string ("") with wxProtocol::GetContentType()
and error code: 45157104 with wxProtocol::GetError(). It doesn't help me
a bit with solving the problem. Any other ideas?

Regards,
Peter
