I've set up a server using winsock, and it accepts
and deals with connections just fine and I'm happy
as a bunny, but is there a way to determine the IP
address of the remote client?
I know it must be possible, but I'm new to this
so thanks for any help!

I'm going nuts. Not a particularly arduous trip, given my starting point, but not pleasant in any event. I'm doing a trivial app ( for the rest of you, not me ) to add CDs to a database. As the primary input screen I have a dialog box that allows 16 rows of input, selected because I don't have any CDs that hold more tunes than that. In each row I have a group of radio buttons to indicate whether each track is a solo, a duet, or a group song. The first button of each row has the Group property set; the other two do not. In all other respects every button is identical, and this pattern is consistent for all rows.
When I compile and execute the code, row 8 interacts with row 9, though all other rows behave exactly as I'd planned. Row 8, by itself, works great, but when I select the second button in row 9, the third button in row 8 clears instead of the first button in row 9! Selecting the third button in row 9 clears the first in that row, but the second is unaffected.
I thought I had a clue when I discovered that the numerical order on the defines for the buttons was a bit skewed for these two rows, so I edited them to follow the proper sequence and saved the whole project. But after rebuilding all, the behavior persists! Suggestions would be most welcome - I'm out of ideas!

They need to be in the order you want in the resource editor, so that the first of each group is first, followed by those in that group, then the next group starts. You should be able to do this by setting the tab order, and you may have done so, from what you said, and failed to save it OK. If that does not work, look in the resource file.
Or use C# and declare a radio button group. :P

If this wasn't so frustrating, I'd laugh. Every time I try to make VC do something useful, it pulls something like this on me, and I toss it out for a year or so. The order of the controls is correct, the files have been saved repeatedly, yet the behavior doesn't change. I suspect the next step will be to delete both rows and start over - I predict that this will cause the rest of the rows to misbehave, based on past experience with VC. The really annoying thing is that these two rows of buttons are set up exactly the same as the other 14 rows, and those 14 behave perfectly! There has got to be some setting somewhere that the IDE won't let me see that's causing this trivial thing to fail.

Hi.
I am working on a HTTP client. I want the program to download a specific webpage. The program initializes a connection to the web server and requests index.html.
GET index.html
However, for some reason most web servers I tried have responded with errors about bad requests. I would like to know what is the HTTP command to download a website such as index.html?
Thanks,
Kuphryn

> telnet www.msn.com 80
Connecting to www.msn.com.....
GET / HTTP/1.1
Host: blah
Todd Smith

Okay. Thanks.
GET / HTTP/1.1
That works on some website, buts not all. I will continue debugging. HTTP programming is depends on more on the web server than an absolution solution on the client side.
How do popular web browser including IE and Netscape handle all web server? There are many possible HTTP commands and combinations.

Some web servers requrie a valid Host: entry which is usually
Host: <your ip>
and some even check the Agent: header
Agent: Mozilla (blah blah)

The GET line should contain the full URL and HTTP version:
GET http:
|
|
|
|
|
Okay. Thanks.
I will try that approach.
Some server require the Host to be exact. For instance, www.xyz.com might want members.xyz.com. There is no way to determine what the server wants without first seeing an error response.

hi everyonebody,
i have a popup menu, activated by right click.. i want to disable some of the commands in the menu.. i was wondering how do i do it? i've different ways, but i can't seem to get it working.. any suggestion is welcome.. thanx in advance.
i've tried this:
void CMyApp::OnRMrclk(....)
{
CMenu menu;
CPoint point = GetMessagePos();
menu.LoadMenu(IDR_MENU1);
menu.EnableMenuItem(ID_MENU1_ONE, MF_GRAYED);
menu.GetSubMenu(0)->TrackPopupMenu(TPM_LEFTALIGN | TPM_RIGHTBUTTON, point.x, point.y, AfxGetMainWnd());
}
i've also tried this:
void CMyApp::OnUpdateMenu1One(CCmdUI *pCmdUI)
{
CMenu * pMenu = pCmdUI->m_pMenu;
pMenu->EnableMenuItem(ID_MENU1_ONE, MF_GRAYED);
}

Every once in a while I hear this pop up that break statements should only be used in switch statements and continue is just bad.
IMHO, this is a question of style and thus I am not interested in if it is right or wrong. What I would like to know, how many people think that break/continue are bad and how many do not.
So? What do you guys think?
Tim Smith
I'm going to patent thought. I have yet to see any prior art.

I don't like using them except as you say break should be used in switch statements.

I use break all the time to exit simple loops (yes, I know this is a "violation of structured blah blah..." but I couldn't care less  ). As for continue, I don't use it that much.

All generalizations are false. 
break and continue have their place. Every programmer knows what they do, so using them won't cause others to scratch their heads in confusion. (Unlike something more esoteric, like say complex templates.) If the code is readable with those statements, then by all means use them.

break in a for loop often shows a while loop should have been used. In switch statements, I don't see what the problem is.

I think those break/continue discussions, as well as some other structured programming mottos like "one return for function" are a little outdated these days. Most complexity in today's programs comes (hopefully) from OOP architecture, not the design of local code. Personally, I tend to use whatever resources that make the code more understandable and/or simple, and breaks inside loops are often very handy.

I love them. I think they can make for more readable,
better documented loops-- especially in those loops
with large bodies. I say use them when control flow
is easier to picture because of it. I personally hate
to read code that is deeply nested for no other reason
than style.

Hi,
I have radio buttons in my dialog and want to disable some of them according to the state of other radio buttons. The problem is that it seems impossible to add a member variable for radio buttons in MVC++6! (but check boxes are ok)
I basically want to do the following:
m_radioButton1.EnableWindow(false);
Thanks

the Wizard will create only one variable for a radio button group, the one variable contains the "index" of the radio button of the group that is chosen.
I think you can add them manually ( preferrable since you'll learn something more ! )
you can always do :
CButton* pButton = (CButton*)GetDlgItem( IDC_RADIO_BUTTON1 );
pButton->EnableWindow( FALSE );
Max.

Thank you a lot Max
