Herecan say, numptr is a pointer to an integer and it has the address of the location where 5 is stored

char * number = "five is number";

However here is it right to say that the 'number' is a pointer to a char and stores the address of the first character in the string(f). If it is, then why does the statement,

cout<<number;
gives the string itself as the output and not the address where the character 'f' is stored.

   ADDRESS     VALUE
number          'f'
number +  1     'i'
number +  2     'v'
number +  3     'e'
number +  4     ' '
number +  5     'i'
number +  6     's'
number +  7     ' '
number +  8     'a'
number +  9     ' '
number + 10     'n'
number + 11     'u'
number + 12     'm'
number + 13     'b'
number + 14     'e'
number + 15     'r'
number + 16     '\0'

Also what does '&number' mean when 'number' is a pointer.

int i; // a integer variable
int * p; // a variable who holds the address of a integer variable
int * * pp; // a variable who holds the address of a variable pointing to a integer
int k;

i = 5;
p = &i;
pp = &p;
k = **pp + 2; // what is the value of k?

4. Now i have changed my configuration file and i want to reload the config map without restarting my process
5. lots of places i am already accessing this map

How safely i can reload my configurations?

void CMyClass::GetDirectory( CString & szPath )
{
  CPath path( szPath );
  path.RemoveFileSpec();
  szPath = (PCTSTR)path;
}

//and here's an example of how to call it.
void CMyClass::OnBnClicked()
{
  CString szBmpPath = _T("E:\\Documents\\1.bmp");
  CString szBmpFolder = szBmpPath;

assume that the length of pBuffer-BUFFERSIZE is bigger than or equals the length of
the buffer of socket,Is there possible that data in the buffer of socket is not
retrieved clearly after calling recv() one time?

is it mean every bytes of data will be retrived after recv() at one time? as long as the size of the buffer supplied is big enough?

Can you please explain me with any example.

1. You replied to the wrong person.
2. The function you're referring to is OnInitialUpdate(), nothing else.
3. OnInitialUpdate() is called before the view is displayed, which means that your progress bar probably won't even show if your code is called from OnInitialUpdate().
4. You have not formatted your code using <pre></pre> tags, which makes it hard to read.
5. At best, the user will still experience a non-responsive application even if your advice is followed.
