I get down on myself at times but I usually snap out of it! Any way, Rodney Dangerfield made a career on "no respect".
I did break the tutoring ethics by supplying code rather than supplying informative suggestions. For that, I slap my own hand. Ouch!
I will make an attempt to create beautiful example code. For, if it looks ugly, it may run ugly.
Thus, on this day of becoming a senior, I will bring forth an effort to be a better poster. I feel rejuvenated already! ![Rose | [Rose]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/rose.gif)

This one is even better. This will work with more types.
#include <iostream>
#include <vector>
#include <algorithm>
#include <functional>
using std::wcout;
using std::endl;
using std::vector;
using std::sort;
using std::less;
template <typename It, typename Pred>
class dereference_predicate : public std::binary_function<It, It, bool>
{
public:
dereference_predicate() {}
dereference_predicate(const Pred &pred) : pred(pred) {}
bool operator()(const It &a, const It &b) const
{
return pred(*a, *b);
}
private:
Pred pred;
};
typedef dereference_predicate<int*, less<int>> pint_less;
typedef vector<int*> pint_vctr;
typedef pint_vctr::iterator pint_iter;
int _tmain(int argc, _TCHAR* argv[])
{
int values[] =
{ 4, 2, 3, 5 };
size_t count = sizeof(values)/sizeof(values[0]);
pint_vctr values_vctr;
for (size_t i = 0; i < count; ++i)
{
values_vctr.push_back(values + i);
}
pint_iter begin = values_vctr.begin();
pint_iter end = values_vctr.end();
less<int> less_than;
pint_less dp(less_than);
sort(begin, end, dp);
for (pint_iter i = begin; i != end; ++i)
{
size_t index = *i - values;
wcout
<< L"values["
<< index
<< L"] = "
<< values[index]
<< endl;
}
return 0;
}

if i have understood your problem correctly, then here is the solution.
while sorting the first array, perform the swapping of the elements in the second array also.
means, the items in hte second array need not be sorted right?
but there will always be one to one mapping among both the arrays.
if my post didnot answer you,
then please explain your task a bit clearer.

I have two .NET 2.0 components:
Component A was purchased from a third-party with a license that they generated based on SNK file that we provided.
Component B we implemented that tries to use component A. It is signed with the same SNK file, and also exposes its interface via COM interoperability.
Now, if I try to use component B from a .NET application, then the license verification for component A fails until I sign my .NET application with the same SNK file, and then it’s fine.
The problem is that the same logic doesn’t work if I try to use component B from a C++ application via COM. My C++ application is unmanaged, written under VS2005SP1. In the project settings I tried to put my SNK file into Configuration Properties->Linker->Advanced->Key File, but to no avail. The way I see it, this option is only applicable to assemblies, which my C++ doesn’t even have.
Question: How do I sign my C++ application with the given SNK file in my case, so that license of component A works just as it does in my .NET application?
Free C++ libraries with source code on www.neatcpp.com: TWAIN, DirectShow, Interprocess Communications, etc...

In a program I've been working on for a while now I've started to have a weird debugging problem. When I hit a breakpoint and start stepping into other methods the debugger will take me to the middle of other methods instead (looking at the call stack the way I've reached the breakpoints is also incorrect, i.e. button click events been called randomly instead of when the user clicks the button). Has anyone came across this before?
I've done the usual of doing a clean rebuild, shutting the machine down, swinging round on my chair whilst counting backwards from 100..... 
I'm working within Studio 2003.
TIA

i hope u have tried deleting the files in debug folder(should not leave any file).Then recompile the program.remove all th breakpoints and do start from first...

It sounds like the .PDB file is out of sync.

Actually, the problem is probably a corrupted .ncb file.
Close the project, then delete the .ncb file and also delete any .aps or .clw file that may exist. Then reopen the project and you'll probably be OK.
Hope that helps.

Hi all, thanks for al of your replies. I tried all of them with no success and then finally found the answer on the MS Support site
http://support.microsoft.com/?id=328784[^]
This has fixed my problem and I think the problem crept into my program when I integrated some code that someone I work with wrote in a text editor (he switches between Linux and Windows) so this seems the likely culprit.
Thanks all again,
Andy

If there is? Can you give me quick overview?

I'd add that you also need a Windows Live ID or a Passport account. So technically it's not been released to the public at large like SP1.

In my MFC application i am reading remote directory of a unix system, using CFtpFileFind class it returns the file names along with times but the seconds field is always zero, here is the code
CFtpFindFile finder .......
..........
..........
CTime ct;
..........
..........
finder.GetLastWriteTime(ct);
int hour = ct.GetHour(); // fine
int min = ct.GetMinute(); // fine
int secs = ct.GetSecond(); // always zero on unix sys
//its not zero
Please help why its so, or there is some other method to read seconds.
Thanks in advance![Rose | [Rose]](https://www.codeproject.com/script/Forums/Images/rose.gif)

I think you'll have to show some more code. It's not clear how you have actually 'found' any file since there has to be at least one call to FindNextFile. Also, I'd check the return value of GetLastWriteTime() just to be sure that it returns TRUE.

Did you check your unix system records file times with better than 1 minute resolution?
just log in and use some interactive commands such as "ll".

Hello everyone,
I read MSDN document about reserve method of vector, but I can not find answers to the following 2 questions after reading it,
1. if we reserve 10,000 size, will the memory actually be occupied 10,000 size (like committed memory of Windows Virtual Memory management) or the memory will just be reserved for future use (like reserved memory of Windows Virtual Memory management);
2. Will reserve method of vector improve performance? If yes, could anyone share some experiences please?
If reserve method has any additional benefits beyond performance, please also let me know.
thanks in advance,
George

Yes.

It may if you are adding elements at the end.

Thanks Nemanja,

When n supposes an expansion in capacity, a reallocation happens during the call to this function, granting that no further automatic reallocations will happen because of a call to vector::insert or vector::push_back until the vector size surpasses at least n

Thanks led,
I can understand reserve will improve performance of push_back, but how will reserve improve the performance of insert? Seems you (or the article) means that reserve will improve the performance of both insert and push_back.
regards,
George
