wxURL not working in 2.8.0

[javastro]

I had a piece of code to retrieve an HTML page from Internet that worked in 2.6.3 and now it doesn't work in 2.8.0. It was built around wxURL and the snippet provided in the documentation for GetInputStream. It is actually the call to this method that is failing, returning a null pointer.

I've also noticed that the sockets sample is not working for me in 2.8.0.

I've loooked through the sources without being able to find a reason or solution. Does anybody have a workaround?. Thanks.

Try GetProtocol().SetFlags(wxSOCKET_NOWAIT).

I had the same problem lately. Try moving your wxURL code into second thread. It helped in my case. Still I don't understand why

Code: Select all

	wxURL url(address);
	if (url.IsOk())
	{
		url.GetProtocol().SetTimeout(20);
		wxInputStream* stream = url.GetInputStream();
		if (stream)
		{
			wxMessageBox(_("ok"));
		} else
		{
			wxMessageBox(_("faild"));
		}
	} else
	{
		...
	}

works in secondary thread, but fails to get stream in main thread.

I use wxHTTPEngine for all my HTTP transfers... See wxCode for that. IIRC wxURL was "deprecated" but strangely it hasn't been removed... even though it was "deprecated" since 2.5 (or 2.6, I'm not sure)

Warm thanks to all that so kindly replied to my initial post. None of the approaches have worked. Reading other posts I've noticed that currently it seems to exist a number of errors and unstabilities around the sockets implementation in wxWindows, and now I'm looking for some external library to do the job.

Thanks again.

I had a similar problem. I was trying to get the contents of a text document from a webserver.

The GetInputStream function returned a null pointer.

My problem was i had the calls to wxURL in a seperate thread and hadn't called wxSocketBase::Initialize() in my wxApp::OnInit() function.

That might help you (or it might not )
