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[^].

Is there a sample for using ActiveX without registering it?

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"
   }, {

         cout << "Combination number. " << Total << endl;

         for (unsigned i = 0; i < combination.size(); i++)

         cout << endl;
   }
      system("PAUSE");
      return EXIT_SUCCESS;
}

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.

DDX_CONTROL in lieu of ::Create for Cricheditctrl

Hi,
Can I use DDX_CONTROL instead of create to connect my rich edit control defined in my resource file
thankx

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

hi ppl,

I got this framework which obiously includes windows.h... Mad | :mad:

And I got a static library which includes afxwin.h.
I need afxwin.h because I want to use CCmdTarget class.

And I got this error: WINDOWS.H already included. MFC apps must not #include <windows.h> Mad | :mad:

I am not creating a MFC application and I need CCmdTarget class and I cannot remove windows.h... Unsure | :~

Any workarounds?? Confused | :confused:

Thank you all.. Smile | :)

The CCmdTarget class is part of MFC.
So you don't have the option of not using MFC.

You can include all the MFC stuff first. This way, you can be sure that windows.h is already included for the framework that comes next.

But, like the other poster said, you are going to be building an MFC application.

MFC CreateEx function crashes program

ChrisBuckley2-Oct-09 3:23

2-Oct-09 3:23

I have been updating an MFC application that has the following line of code in it to create Edit Boxes (Note tmp is a CString object):

CreateEx(WS_EX_CLIENTEDGE, _T("EDIT"), _T(tmp), WS_CHILD | WS_TABSTOP | WS_VISIBLE, *pMyRects[0], pParent, resourceId);

Up until recently, this code has worked fine. On my latest build, only the Debug build works. The Release build crashes. I traced the crash to this particular line of code. The CreateEx function actually never returns. I can't debug it, since as I said the Debug configuration doesn't crash.

What's weird is when I replaced the _T(tmp) parameter with _T("") so the line looks like below, the Release build doesn't crash.

CreateEx(WS_EX_CLIENTEDGE, _T("EDIT"), _T(""), WS_CHILD | WS_TABSTOP | WS_VISIBLE, *pMyRects[0], pParent, resourceId);

I've googled this issue and can't find anything like it anywhere. Does anyone know if there is some issue passing a CString to the CreateEx function or if there's a problem because the CString was created locally in the function?

Another strange quirk is that I ran the Release executable on a machine with Vista (rather than XP which is what I am developing on) and the code doesn't crash.

Why are you using the _T() macro on a CString ? Try removing it and see if this fixes your problem.
