Hi,
When you run this tool handle.exe from http://www.sysinternals.com/ntw2k/freeware/handle.shtml
you will see the names of the MMF sections, for eg:
\BaseNamedObjects\C:_Documents and Settings_test_Local Settings_History_History.IE5_MSHist012004050420040505_index.dat_49152
1. I want to know how handle.exe gets this name from? Is is available from some standard API or its just the path name with '\' replaced with '_'? Its unlikely, as what is 49152 about?
2. I could open this MMF section with OpenFileMapping and could walk through using the memory address. Is there a way to obtain the size of this MMF section? We dont know the file name for this section so that I can use GetFileSize.
3. Any good articles that discusses MMF?
Thanks

when i run my program via VC++ (by pressing F5) a specified function (OnSize) is called while when i run it outside of VC++ it isn't!!!
i checked it by writing something in a file.
please give a technical answer, i've examined all ordinary cases.

I can give you 3 possible solutions.
1) Do a complete rebuild.
2) Is your file closed? if that doesn't work try to flush it first.
3) Set a Beep command 
If these don't work, I don't know it either. (but sometimes I have the same problem and these always worked)
Good Luck

Hai,
I am quet new to Visual Studio. I want to write my database programs using the Dialogue Box forms instead of Single/multiple Documents forms.
It is queit is easy to do it using documents. But I dont like the forms. I prefere using Dialogue Boxes to write Database programs.
How I can I access the Database when using dialogue Boxes.

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!

case WM_PAINT:
hdc=BeginPaint(hwnd, &ps);
TextOut(hdc, 0, 0, "I love you.", 15);
EndPaint(hwnd, &ps);
return 0;
case WM_SIZE:
return 0;
case WM_CLOSE:

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.
