Well, i finnaly got the app to read from a file, anyways, it only reads up to a space, then it stops (unless you read from the file again, in a loop or something - of course each time its like a new line)
Anyways, im sure y'all already know that, and you may have guessed the question, how do a read a whole line upto an newline constant of some kind, rather that a space?

Use the getline() method.

Thanks for you help at first!
I'm a chinese student and my english isn't very well! A I really want your can give me some help on my english and computer courses(I'm very interesting in Visual C++)!
I'm a tenderfoot about C++ language!
I'm confusing by the question as follows:
there is parts of my code:
int a=10;
int* ap=&a;
char c='b';
char* cp=&c;
when I want to get the vaule of the Pointers point to;
cout<

Yeah, i got garbage as well, except i had a whole array of chars (an entire 7) to get round the problem, i had to write out each character at a time, a bit much effort really

you get garbage values after the character 'b' because the operator << is overloaded for a code char* parameter, to be a C-style string.
such a string is supposed to be NUL terminated (with '\0'), so it read from the beginning (the 'b' character) until it finds a '\0' character in the memory after the 'b', even if it is not yours.
if you want to see the address of the pointer, do this :
cout << (const void*)cp;

Of course. One points to an int and the other points to a char.

Did you look to see what << operator was being called?
cout << (const void *) cp;

David, just a personal wondering, but here, is there a reason to use (const void*) more than the non-const (void*) cast ?
i don't see anything serious, so maybe you could light me up...

It matches the method's signature.

I always receive following error when compile the win32 vs project written in C. But I checked the makefile and couldn't find any variable at the left of the equal sign is not defined.
Any suggestions???

Can you whittle the makefile down to just the lines necessary to reproduce the problem? Is the macro name being complained about itself a macro that expands to nothing?

Hi all,
I am using a CFile class to work with a file and I would like it to retain its original date and time setting. I obviously forgot what to use to get and set the date and time of a file. Pease help (I seem to remember that I should not use the CFile class itself but maybe do something with CFileFind; however this gets a file date and time, but does not set it)
Thanks in advance,
William

Why are you not using CFile::SetStatus()?

I think that you will have to override the right-click/WM_CONTEXTMENU and provide your own. I do not think it is possible to directly modify the the edit control's menu because I think that menu is built-into the edit control and is a standard feature of Win32 (ever since Win2K or Win9x, I believe).
A global hook can simulate a modification to the shared menu...
Peace!

Hello everybody
I am trying to launch "An All-Purpose Keyboard Hook"(http://www.codeproject.com/system/KeyHook.asp[^]) dll with my application, but not successful... I have no idea why dll doesn't post messages to my application.  This is a source code:

m_entry.nMessage = WM_MYTHREADMESSAGE;
m_entry.hCallWnd = (HWND)Thread::m_hThread;
m_entry.hHookWnd = 0;
m_entry.iCombKeys = 0;
m_entry.iIndicators = 0;
m_entry.iKeyEvent = 0;
m_entry.iMinVKCode = 0x00;
m_entry.iMaxVKCode = 0xff;
if(AddKeyEntry(&m_entry) != KH_OK)
{
theApp.FileWrite("AddKeyEntry failed\n");
return TRUE;
}
theApp.FileWrite("Thread initialized\n");
return TRUE;
}
int Thread::ExitInstance()
{
theApp.FileWrite("Thread clean up\n");
return CWinThread::ExitInstance();
}
void Thread::MyMessageHandler(WPARAM wParam, LPARAM lParam)
{
char data[64] = "";
itoa(wParam, data, 10);
strcat(data, " <<< WPARAM\n");
theApp.FileWrite(data);
}

WaitForSingleObject(pThread->m_hThread, 5000);
FileWrite("Program terminated...\n");
return TRUE;
}</pre><br />
<br />
