Hey everybody.

I'm having troubles in resolving (using DNSQuery()) a hostname in a subdomain.

I'll explain.
Lets assume MainDomain and SubDomain.
Now, SubDomain is a subdomain to MainDomain (kinda obvious Smile | :)

).

Well... I'm on a host called "maindomain1" and there is a host called "subdomain1".
When I am using DNSQuery() from "maindomain1" to "subdomain1" I get that "subdomain1" does not exist.
What I actually need to do is to place subdomain1's full name:
"subdomain1.SubDomain.MainDomain.com" and it will work.

BUT, I don't want to place the full name!
"Ping" for instance can resolve only by getting "subdomain1", while nslookup can't...

I want to know how "Ping" know how to resolve that subdomain1 name,
Or in other words, is there a C++ function that receives "subdomain1" and returns "subdomain1.SubDomain.MainDomain.com" ???

Thanks a lot!!!

How are you using it? There are several parameters with many options. You did not post your code so we don't know what you are doing. Also what domain are you trying testing with?

Right

So, I have the following code:

<br />
std::wstring host(_T("subdomain1.SubDomain.MainDomain.com"));<br />
<br />
DNS_RECORD* pDnsRecords;<br />
DNS_STATUS stat =  DnsQuery(host.c_str(),<br />
			DNS_TYPE_A,<br />
			DNS_QUERY_NO_HOSTS_FILE,<br />
			NULL,<br />
			&pDnsRecords,<br />
			NULL);<br />

The code above, works great.
B-U-T, I practically, I do not want to use the full name of the host, which is:
"subdomain1.SubDomain.MainDomain.com"
Only it's name "subdomain1".

Now, when I perform the operation: "ping subdomain1", "ping" does resolve the correct IP without the full name, that means it is possible for sure.

What I want to know, is that if I get from the user the hostname:
"subdomain1"
how can I find out that it's full name is:
"subdomain1.SubDomain.MainDomain.com"

to use in the DnsQuery() that is written above?

Thanks again!

To disable them is dead easy with MFC. You just provide an ON_UPDATE_COMMAND handler for a command, and away you go.

For 99% of my menus, I prefer to go this way. Then a user can say "ah, here the option is, I just can't use it right now for some reason".

The option is the one MFC uses by default - switch the menu set completely. It has one for "no view", and each view has an associated menu it puts in place. No point in having much more than open, close and help for an MDI app with no documents... I just use one global menu, but their approach is a perfectly good one.

The last thing I do is to have a setup submenu on my Tools menu. The first menu option on that submenu has an ID of IDM_CONTROL_EDITBUSFILE. If the user has not put a specific flag on the command line, I remove the submenu completely. This saves them accidentally doing something that only knowledgable people (ie me and my colleagues) can do.

ON_UPDATE_COMMAND_UI(IDM_CONTROL_EDITBUSFILE, OnUpdateControls)
...
void	CIOBus::OnUpdateControls (CCmdUI* pCmdUI) 
{
    if (pCmdUI->m_pSubMenu)	// Whole of the control submenu
    {
        // Is this the Tools | Setup system sub menu we are validating?
        if ( (pCmdUI->m_nID == IDM_CONTROL_EDITBUSFILE) && !CGlobals::IsSettingUp () )
            pCmdUI->m_pMenu->DeleteMenu (pCmdUI->m_nIndex, MF_BYPOSITION);
        return;
    }

Have a look at this article:

It shows using a toolbar and a rich edit to make different colour / fonts / sizes etc in a rich edit control.

The article contains exactly that info too, in addition to the system tray stuff. Skip the parts about the system tray and read how to make a single instance program.

When you run an instance of your exe, first you can check if another instance is running. If it is then make old instance visible and exit from the new instance.
