How you present the data has no bearing on how you access the data. In either case, derive a class from CRecordset.

Don't care, don't want to know. I never want to see a single line of OS code that isn't legitimately in the public domain, purely to avoid a situation later where MS hit anyone who has 'remembered' so much as that single line.
If you admit to having read it, how do you prove you aren't using (copyrighted) code from it, for example?
The fat man is either raving, or stupid to even post that question, in my opinion.

I doubt that it is the entire code. IIRC some service pack code was stolen at one time.
Anyway bad choice of question for an open forum!

Just fix:
<br />
LRESULT CALLBACK mainWndProc( HWND hwnd, UINT uMsg, WPARAM wParam, LPARAM lParam)<br />
{<br />
HDC hdc;<br />
PAINTSTRUCT ps;<br />
switch (uMsg) <br />
{ <br />
case WM_CREATE: <br />
return 0; <br />
case WM_PAINT: <br />
hdc=BeginPaint(hwnd, &ps);<br />
TextOut(hdc, 0, 0, "I love you.", 15);<br />
EndPaint(hwnd, &ps);<br />
return 0; <br />
case WM_SIZE: <br />
return 0; <br />
case WM_DESTROY:
PostQuitMessage(0);<br />
return 0 ;<br />
}<br />
return DefWindowProc (hwnd, message, wParam, lParam) ;<br />
}<br />

Hi,
I am a newbee to programming using c/c++. I want to find out total memory occupied by a linked list in the memory. What is the easiest way to find it out.

|

I am not sure, but... how do you think:
std::list<T> foo;<br />
foo.size() * sizeof(T) + sizeof(foo);

what sort of list ? list<> ?
or a simple array ?
for an array, you should have a trailing NULL at the end, to get the size (unless you already know the size you allocated).
for a list<> you get the nember of elements in the list that you multiply this by the size of an element, plus the size of the list object itself.

(1)list constructed ,what is its elements type? ie:list<int> ,list<string>,list<char> ..
(@) if list<int>,by sizeof(int) ,i can know the byte occupied by the type in your computer,then setting a varible , by iterator i can know the elements numbers in list.by this ,i can know the list occupied the byte number in member
but if list<string>,the case will be a little trouble,you need check out the words numbers in every string,the left solving way are similar the above

I want to develop a tool which is similar with test automation tool. This tool launches a cmd window and writes some command lines in that window. Now I am able to get cmd window handle, but I don't know how to write the lines. Could anyone help me and I will appreciate it. Here is the code I have done.
WinExec("cmd.exe", SW_SHOW);
CWnd* pDeskWnd = CWnd::GetDesktopWindow();
CWnd* pPrevWnd = pDeskWnd->GetWindow(GW_CHILD);
while (pPrevWnd)
{
CString s;
pPrevWnd->GetWindowText(s);
if (s.CompareNoCase("C:\\WINDOWS\\System32\\cmd.exe") == 0)
{
if (pPrevWnd->IsIconic())
pPrevWnd->ShowWindow(SW_RESTORE);
pPrevWnd->SetForegroundWindow();
pPrevWnd->GetLastActivePopup()->SetForegroundWindow();
CWnd* pCmd = pPrevWnd->GetActiveWindow();
// CPoint id = pPrevWnd->GetActiveWindow();// GetDlgCtrlID();
// pPrevWnd->SetDlgItemText(id, "A command");
/* CDC* pDC = pPrevWnd->GetDC();
pDC->TextOut(0, 100, "A command I want to issue ");*/
return;
}
pPrevWnd = pPrevWnd->GetWindow(GW_HWNDNEXT);
}

But the cmd.exe window is not listening.

I'm just starting to do some socket programming (non-MFC) and had a couple questions. Is there a ReadLine function to read a single line from a socket? If not would a line be terminated by a \r \n or both? Lastly is there a function to "peek" at the data waiting to be read? Like the peekmessage that would allow me to retreive the the waiting data without actually removing it from the socket?
Thanks.

use the recv function to read from the socket.
the recv function can be blocking or non-blocking
according to the connection specified...
these sockets are known as synchronous sockets
but, if u wish to get a notification whenever a message reaches the port , then use asynchronous sockets.
there are various options: FD_READ|FD_WRITE|FD_CLOSE|FD_CONNECT
, etc etc...
u have to use the API: WSAAsyncSelect....
search for the API in MSDN and include the required library and header file..
i think the library is : Ws2_32.lib
and header file is winsock2.h , i think winsock.h will also work...
u have to create a user defined message:
#define MY_MSG WM_USER + 100 OR something.... as u wish...
this is one of the arguments in the API call....
we can achieve this also using synchronous sockets , but asynchronous is much more easy....

To my knowledge, sockets do not know what "lines" are. That is a notion understood by us, and some text editors.

ioctlsocket(..., FIONREAD, ...); is but one way.

Has anyone here used c-tree plus by FairCom in a real application. I'm especially interested if you did any performance and ease of coding/maintenance comparisons with MSDE.
Anyone who thinks he has a better idea of what's good for people than people do is a swine.

I did, albeit some time ago, and it predated the availability of MSDE, so I can't give any comparisons. However, I do recall it being as fast as, say C-ISAM from Informix, in the tests I ran. That said, both of them were lower level (ie non-SQL) than MSDE, which meant writing test harnesses for stuff rather than just using Query Analyser to make sure I'd get what I want.
FWIW, my advice would be to avoid anything there isn't an ODBC or OLE DB driver for on a Windows platform - that way you can use tools like MS Query and Crystal Reports, which can save lots of time in the development cycle. However, if you have real performance constraints, and no need for high level access (you can do your own query plans etc), then an ISAM type package can make a real difference (although I'd look at D-ISAM as well).
