The 'X' button is on the frame window not the form window. Try handling it in the frame window
class instead.

I added the WM_CLOSE command in my MainFrame class.
But now the problem is that I am not able to retrive data from the input boxes of my CMyFormView.
The program Asserts when GetWindowText is called.
void CMainFrame::OnClose()
{
CMyFormView pFV;
pFV.OnAppExit();
CFrameWnd::OnClose();
}
<p\ pre="">
<div class="ForumSig"><hr><font color="brown">Fortitudine Vincimus!</font></div>
|
|

How about this...
void CMainFrame::OnClose()
{
CMyFormView *pFV = (CMyFormView *)GetActiveView();
pFV->OnAppExit();
CFrameWnd::OnClose();
}

Yipee!! It worked!! Thanks a billion!!
GetActiveView() - so thats the way. Create an object of the view and then set the focus on it.
Thank you once again.

Cool!

The view object already existed. You just needed a pointer to the one in existence, not a new
object. The assertion was from the uncreated new object (no HWNDs).
Glad it's working!

By the way, if you want to give the user choices before closing then give the user the choices
BEFORE calling CFrameWnd::OnClose(). Only call the base class if the user chooses to exit the
app. If the user cancels or chooses to continue, just return from your OnClose() method.

What's wrong with the app's ExitInstance() method?
You could also handle it in the frame's DestroyWindow() method.

Dont know about that.

The problem with DestroyWindow is that it closes off the application. I put a MessageBox there and checked how it worked. The application closes and then the MessageBox is displayed. Whereas I need to give the user some choises before the application closes.

Normaly,the selected item and the unselected items have different item height.
Is there any way to change the height?
I want a tabctrl that the selected and the unselected items have the same height without owner draw.
Because,xp theme would not take effect on a owner draw control.If I try to enbale xp theme on a owner draw button,it seems easy.but for a tabctrl,I got a lot problems.
thank you for your attention.

Just how is it that you know the DNS server was configured using C++?

Does GetAddressByName() with NS_DNS namespace give you the addresses you're looking for?

Three posts about the same topic? Why not reply back to one of the people that have tried to help you already?
Your posts are very confusing, what do you want to do with the aforementioned files?
I take it you have two files you would like to rename?
dib.cpp & .h (which isn’t a valid file name)
Going out on a limb it almost sounds like you wan to rename those files to cdib.cpp & cdib.h? Why would you want to do that? Most Coding conventions separate Class name from the file name (mostly to easily distinguish the two).
I'd love to help, but unfortunatley I have prior commitments monitoring the length of my grass. :Andrew Bleakley:

hi!
Could you please recommend some c++ library for networking tasks? I tried BOOST.ASIO, but it is only at the development stage, and IMO there are many bugs there.
thanks!

Hi,
I want to know my local ip address. I am on a local area network. I have used the following code:
char* hostName=new char[255];
if(::gethostname(hostName,255)==0)
{
hostent* localhost=::gethostbyname(hostName);
ULONG ip=inet_addr(*(localhost->h_addr_list));
in_addr localaddr;
localaddr.S_un.S_addr=ip;
char* localIP=inet_ntoa(localaddr);
CString localAddress(localIP);
AfxMessageBox(localAddress);
}
It always give the 255.255.255.255 as my local address. Can anybody tell me
how to get my own IP. I dont want to use iphelp or any other advanced APIs.
Regards,
Wasif.

Assuming that you have only one network interface (your eth card) and a loopback interface (127.0.0.1), i think you could try to get the name of the local computer, and then resolve it in an ip address .
<br />
char szMyComputerName[0xFF] = {0},<br />
szMyIpAddress[0xFF] = {0};<br />
DWORD dwSize = 0xFF;<br />
<br />
::GetComputerName(szMyComputerName,&dwSize);<br />
Now all you have to to is to resolve 'szMyComputerName' as you did in your example .
Naturally, if you have more than one network interface (eth card, wireless, etc), you have to enumerate them and then you choose the one you want to work on :
<br />
SOCKET sd = WSASocket(AF_INET, SOCK_DGRAM, 0, 0, 0, 0);<br />
<br />
INTERFACE_INFO InterfaceList[20];<br />
unsigned long nBytesReturned;<br />
<br />
WSAIoctl( sd, SIO_GET_INTERFACE_LIST, 0, 0, &InterfaceList, sizeof(InterfaceList), &nBytesReturned, 0, 0); <br />
<br />
for( int i = 0; i < nBytesReturned / sizeof(INTERFACE_INFO); i++ )<br />
{<br />
printf( "Interface[%d] : %s\n",i, inet_ntoa( ((sockaddr_in *)&(InterfaceList[i].iiAddress))->sin_addr ) )<br />
}<br />
Hope i helped ....

replace ur code above with line below:
char* localIP=inet_ntoa(*(LPIN_ADDR)*(localhost->h_addr_list));
It should be work, but I can't tell why ur code doesn't.
wish this could help!

Try this (works on my machines)
char* hostName=new char[255];
if (0 == ::gethostname(hostName, 255))
{
HOSTENT *pHostent = ::gethostbyname(szTempName);
if (pHostent && pHostent->h_addrtype == AF_INET)
{
in_addr inaddr = *(in_addr *)(pHostent->h_addr_list[0]);
char *pAddStr = ::inet_ntoa(inaddr);
if (pAddStr)
{
AfxMessageBox(pAddStr);
}
}
}
