Obviously you haven't memory of unlimited size. If your file is reasonably small then you may allocate memory to read the whole file, otherwise you need to read the (big) file in chunks.

Hello Jiya,
if you have trouble with those apis, then use COleDateTime. Check the sample code snippet for your use,
COleDateTime time = COleDateTime::GetCurrentTime();
CString str = time.Format(_T("%d-%m-%y"));
Regards,
Jijo.

Have you tried:
str.Format("%02d-%02d-%02d",st.wDay,st.wMonth,st.wYear%100);

how to put node at the end of list. I have so:
struct element{<br />
int key;<br />
int idx;<br />
element *prev, *next;<br />
};
in main i have:
<br />
element* head=NULL; ->pointer on begging<br />
element* tail=NULL; ->pointer on end<br />
element* new=NULL; ->pointer for new node<br />
<br />
int el;<br />
new=new element;<br />
<br />
cin>>el;<br />
nov_el->key=el;<br />
add(head,new,tail); <br />
I know how to put node at the beggining:
<br />
void vstavi(element*&head, element* new, element*&tail)<br />
{<br />
new->prev=NULL;<br />
new->next=head;<br />
<br />
if(head!=NULL)<br />
{<br />
head->prev=new;<br />
}<br />
<br />
else<br />
tail=new;<br />
head=new;<br />
<br />
}<br />
How to change this code for adding on beggining so it will add on the end. And everytime new node is added to the end idx from structure element must idx=idx+1;
Thanks a lot

Please use the code block button to post code snippets.
It looks like you aren't completely aware about C++ syntax: new is a keyword (hence a reserved identifier), moreover if you wish (as it appears) execute both the statements
Aljaz111 wrote: tail=new;
head=new;
after the else clause the you've to enclose them in a block ({}).
Please fix your code, be sure it compiles and works and then ask for completion.

What's problem? Code is simple.
void addTail(element*&head, element* new, element*&tail)
{
new->next=NULL;
new->prev=tail;
if (tail!=NULL)
{
tail->prev=new;
new->idx=tail->idx+1;
}
else
{
head=new;
new->idx=0;
}
tail=new;
}

As well as don't trust your mental compiler: new, you know, is a C++ keyword hence, as it stands, your code won't compile.

Hi There.
I am using VS2008, and am facing above problem.
For details, below is what I am doing...
CString strSource = L"Hello";
TCHAR SourceFile[] = strSource;
Please suggest.
Thanks

Found a Solution: Above conversion can be done using _tcscpy function.
Eg:
CString strSource = L"Hello";
TCHAR SourceFile[100];
_tcscpy(SourceFile, strSource );
|
|
|
|
|
Your solution only works on UNICODE builds.
On the other hand, you may easily generalize it with
CString strSource = _T("Hello");
TCHAR SourceFile[100];
_tcscpy(SourceFile, strSource );
to work both in UNICODE and in ANSI builds.

Why do you need it?
Are you sure you need to convert a wide char string into a generic text mappings array?
If the answer to the second question is yes then you need something like:
HRESULT hr;
TCHAR SourceFile[0x100];
CString strSource = CString(L"Hello");
hr = StringCbCopy(SourceFile, sizeof(SourceFile), strSource);

Have you considered including the header wherein CAdderDialog is declared?

For language teaching a student hears a word and then repeats it.
That gives me two wave-files, the first is my own, the second the one recorded by the student.
That one will probably start end end with noise, of which I don't know the amplitude.
The noise may also contain peaks (dropping a pen on the desk).
I can't determine the exact start and end of the spoken word because of possible peaks
and because the word may start and end 'under' the noise level.
I must compare the two waves, which are in two short-int arrays, to see if the student
pronounced the word correctly, based on rhithm, pitch and stress.
So, 'rotor' in reply to 'motor' would be correct, but 'rotter' would not.
Comparing the content of the waves doesn't work, so now I am wondering if using FFT
might be the solution. I have tried WaveInFFT, processing the two arrays the same way and
dispaying them in the same way, but do not see a resemblance between the two graphs.
I hope someone can point me in the right direction.

Hi All,
Can anyone tell me how to get model number, serial number,temperature and other S.M.A.R.T features of external hard disk drive using MFC.
Thanks

Dear All,
Thanks Hamid for your reply.But I have already tried it out.It doesnot show the serial number or model number.It only shows the type as USB.But i need the details of the hard disk as mentioned in my question.Please do reply if anyone finds any clue how to find it out.
Thanks

Which could mean that the mfg. did not provide such information. Do you have proof to the contrary?

Why is the second call mapped to the macro version?
void f() {
puts("func");
}
#define f() puts("macro")
void main()
{
f();
f ();
(f)();
}
Output messages:
macro
macro
func
Press any key to continue . . .

Possibly because 'irrelevant' blanks are removed by the preprocessor before macro expansion happens?
