Hey guys.

I have a toolbar that I'm working on, and I've got it working just ducky except for a few things... I currently it have it redirect on a 404 or whatever to something like: http://www.mysite.com/404.html but I would like to not have it show the URL of the error page in the address bar... Even if I have to somehow make a dll or something that contains the custom 404/etc error messages, how can I go about doing so?

...could you explain why? Or more exactly, explain in satisfying detail that your toolbar is not one of those awful ad bars that i spend so much time cleaning off of relatives' computers. Wink | ;)

It's actually going to be for a game of mine that I run, and it's going to give people stats about the game etc. :P It's not an ad bar by any means. :P

Kewl. Well, not sure where you're intercepting the 404, but responding with a 302 that redirects to your page sounds like the way to go.

Haven't tried it myself, but...

15-Dec-03 18:27

Ok..

Now will that send me to the custom 404 page and leave the original address in the address bar? Smile | :)

As i understand it, it *should*. Now, whether IE actually does this or not... *shrug*

Unfortunately that code redirects just fine, but it shows the URL up top.. Which I don't want, I just want the site that they tried to get to up there in the address bar. Smile | :)

This is what my code looks like here:

void __stdcall CIEBand::OnNavigateError(IDispatch* pDisp, VARIANT* URL, VARIANT* TargetFrameName, VARIANT* StatusCode, VARIANT_BOOL* &Cancel)
{
	if(StatusCode->intVal != HTTP_STATUS_OK)
	{
		CStringW c = "http://www.mysite.com/404.html";
		VARIANT_BOOL topLevel;
		if(m_pWb2 == pDisp && SUCCEEDED(m_pWb2->get_TopLevelContainer(&topLevel)) && topLevel)
		{
			//redirecting = true;
			m_pWb2->Stop();
			//*Cancel = VARIANT_TRUE;
			m_pWb2->Navigate2(&CComVariant(c), &vtMissing, TargetFrameName, &vtMissing, &vtMissing);
		}
	}
}

I'm not sure... I have my code below, and I'm not quite sure that'll work...

Well... can't give you a good solution, but here's a hack that might do for you. Navigate to this URL (replacing winamp.com with whatever):

javascript:document.write('<body style=\"overflow:hidden;margin:0px;padding:0px;border:none;\"><iframe src=\"http://www.winamp.com/\" style=\"margin:0px;padding:0px;border:none;width:100%;height:100%;\"></iframe></body>')

Hi!
In MFC how can we find the ip address of our own computer?
Thanks. Smile | :)

Try gethostname() followed by gethostbyname().

hi Ravi,
thanks for pointing to that message. but this is what i meant--
is it possible to obtain ipaddress of a computer, when it is not connected to network. say u run mfc application on your computer and it prints out the ipaddress of your machine. i was wondering if there was any function available in mfc for this purpose.
thanks.

I suspect David's solution may just return 127.0.1.1 ("localhost") if you're not part of a LAN. Perhaps you want this[^] article?

I'm a tyro at VC++, but I've been following this thread with some interest. Forgive me if this is a stupid idea, but is there some way you can capture the output of a call to ShellExecute on the command ipconfig? If you're disconnected you may have to add the /all option to make it cough up inactive connections, and you're probably going to have to parse a bunch of text to capture the IP address. Just a thought - I haven't tried it. But I hope that it might provide some sort of solution, however kludgy it might be... Blush | :O

Hi,

The ShellExecute doesn't output the text returned by ipconfig, but you can redirect the output from ipconfig to a file!

For exemple: in the console (command prompt if you will) one can type
"ipconfig /all > somefile.txt".
This way the output will be written in "somefile.txt". If it doesn't exist, it'll be created.

Knowing this, the call to ShellExecute() will look like this

<FONT COLOR="blue">int</FONT> nResult = ShellExecute(hYourMainWindowHandle,
                           NULL,
                           "ipconfig /all > SomeFile.txt",
                           NULL,
                           NULL,
                           0
                           );

All you have to do is parse "SomeFile.txt".

Hope this helps Smile | :)

That was my thought - redirect to a file and read it back. But I assumed someone smarter than I might know a way to do it more efficiently C++. In Java, of course, you'd only have to do a

InetAddress address = InetAddress.getByName(<host url="">);
byte[] addressBytes = address.getBytes();

to retrieve the machine address. Smile | :)

Yes, see these MSDN articles for examples:

I need to present a dialog to the user similar to an installer license agreement dialog. What is the best way to present many read-only lines of vertical-scrollable text to the user with automatic horizontal word-wrapping? I thought that something like word-wrapping would be a basic feature for the MFC CEdit control, but I couldn't find any option to enable it.

Static text controls have vertical scrollbars? How do I enable them?

Shog⁹15-Dec-03 11:53

Make sure the multiline style is set (ES_MULTILINE), and make sure the automatic horizontal scrolling style is not (ES_AUTOHSCROLL). Also set ES_READONLY if you do not intend for it to be edited.
