Is it trusted that a running exe replaces itself by download new version?

A running exe checks version info, if find new, can the exe download new version of itself and replace the exe? is the peplace process trusted?

Yes

No, the exe file will be locked by the OS as it is a running process. You can however save the new file under a different name and call the MoveFile function and specify the MOVEFILE_DELAY_UNTIL_REBOOT flag to have the OS replace the exe file the next time the machine is rebooted.

If memory isn't a constraint for you, a hash table will give you the best performance for searching. The MFC template class, CMap http://msdn.microsoft.com/en-us/library/s897094z%28VS.80%29.aspx[^] is a prewritten hash table. You can also use CMapStringToPtrhttp://msdn.microsoft.com/en-us/library/078kzfk0%28VS.80%29.aspx[^].

ActiveX can not be used if without register it.
but you can register it in main program, so it looks not registered - or you can unregister it when main app exists.

MSDN has a sample about how to register ActiveX, just a few of lines, very easy.
I can not remember the sample name - regsrv32 or some name similar to this.

How to count repeating elements in an array ?

Hi guys,
I've just written a piece of code which works fine and now I need to do one more and the last operation to complete the whole project. I'd like to count how many times all elements in each combination repeat. To be more precise I'm   interested in number of occurences which are equal or bigger than six. Here's the code. You can use it for your studies if you want:

#include "IndexCombination.h"
#include <iostream>
#include <string>
#include <vector>
#include <algorithm>
#include <iterator>
#include <map>
#include <sstream>
using namespace std;
using namespace stdcomb;

bool GetNextComb(std::vector<unsigned int> &vi);
      struct Element
{
   char name[6];
   int numbers[30];
   char chain[90];
};
const Element elements[] = {
   {
         "ia11",
         {3,9,17,21,24,31,33,36,42,49,4,8,19,22,28,30,34,39,43,47,2,6,10,13,14,25,29,37,38,46},
         "3,9,17,21,24,31,33,36,42,49,4,8,19,22,28,30,34,39,43,47,2,6,10,13,14,25,29,37,38,46"
   }, {
         "ia34",
         {1,6,12,15,22,27,31,32,41,42,4,7,14,17,23,30,33,36,45,48,2,9,13,18,21,26,34,39,44,49},

I know that only a few lines are needed to achieve the goal. I've read quite a lot on the subject, but somehow can't figure out how to do it.
Can anybody help me ?

And what error does the compiler give you when it stops? Confused | :confused:

What is the output that you are expecting? I'm just guessing, but I don't see any relevance to the name and chain members of the structure. If that's the case, remove them from the problem.

As far as i can tell from what you wrote here, yes. (Althorough how you would use "create" to connect a member variable to a control defined in your resource puzzles me)

Isn't the last parm on the ::create the resource id of the
control defined in the resource file I would think that connects it
to the specfic CWnd object
The reason I like DDX_CONTROL is that it would pick up
the demensions of window/control and I don't
have to figure out the values for the CRect

Thankx

As far as i know the last param of ::CreateWindow (or ::CreateWindowEx if that is what you mean) isn't what you think it is. However, you can use DDX_Control to attach a control variable to your rich-edit easily.

Sorry for the delay in responding but had some religous holidays

what I meant was the deminsions of the edit control would be picked up from the resource file defination
plus the style bits e.g. ES_MMULTILINE

After DDX_CONTROL do I still have to a create though ??

Then i understood correctly. No, you do not need to create it, it is done for you when you create the dialog (directly by calling Create or indirectly by calling DoModal on the dialog itself), with DDX you simply attach the already exsisting control to your variable.

When I went stepping thru the DDX_Control

The Cricheditctrl m_hWnd seemed to be intialized

I passed the DDX_Control my Myrichedit data memeber (think I am using the right term)

Since this a call by reference doesn't seem like I should need to do any more before using

the Richedit methods on this object

thankx again
