I think you are assuming that a struct in C++ works the same way as a struct in plain old C, but alas it doesn't... well not really anyway.
When you introduce non-primitive data types into structs in C++ they cease to be simple "data structures" and become basically the same as classes only their members default to public instead of private.
My guess is when you try to overwrite the object you are writing over the beginning of its virtual table which probably contains extra debug information in debug mode. In release mode you are then probably overwriting more important class data.
Remember, the sizeof operator is not designed to get the size of an object or its virtual table.

Thanks, that's probably it; me think i will look at the memory a little closer.

hi,
My program creates files dynamically for that I gave location as desktop.
This code I wrote inside a fr loop, that means how many times this loop continues that many number of files will be created. For this situation how can I mention path that should able to generate any number of files.

What are you talking about? You already said that you're creating files on the desktop. What is your query?!

char directory[] = "my desktop";
for (int i=0;i<numFiles;++i)
{
char filePath[MAX_PATH];
sprintf(filePath, "%s\\%d.ext", directory, i);
}?

In addition to Stuart's reply,
There is an API to create file names, uniquely GetTempFileName
It will give a filename in specified directory with the prefix. It will automatically set a unique file name if you insist to do so. Read the MSDN for detailed information. An example is given here

I'm not sure if you got the pun. I've modified the previous post to make it clearer.

I've really no idea as to what you are talking about but if I were to hazard a guess, are you wanting to create a different file each iteration of the loop?

Hi everyone, I got a question about disabling context menu of the web browser and I've searched MSDN, this forum and goole. But seems most of the are either not Dialog Based (most of them use CHtmlView) or not quite same as what I see in my project.
I am using Visual Studio 2005 and Here is my steps of creating the application:
I use MFC application and choose dialog based. Then, in the dialog editor, I add Microsoft Web Browser into the toolbox, and then drag it into the dialog. After that, I right click on that control and choose Add Variable and leave everything default and give it a variable name "myBrowser". Then it automatically creates a explorer.h and explorer.cpp. The explorer.h contains a class declearation of "class CExplorer1 : public CWnd". Then I get stuck at this point. I've tried to declear a message map in explorer.h and find ON_WM_CONTEXTMENU() but seems doesn't work.
From the search of the internet, it seems that I need to implemente IDocHostUIHandler and there I can overload ShowContextMenu() and return S_OK to disable it. But with most of the information I got, seems most of them are for CHtmlView but not CWnd. So, I'd like to ask what I should do to disable the context menu of a Dialog Based Web Browser which inherit CWnd (or my approach is wrong?) and with Visual Studio 2005? (coz I see most of the information are VC++6 and I can't find the same thing in VS2005).
I am new to MFC and these kinds of browser things so my question maybe a stuipd question....
Thanks for any help.

Well, a quick Google shows this article[^] - you'll need to fix up the HTML formatting a bit, but it loks like all the code's there.

how can i convert below code from vbscript to c++
strComputer = "."
Set colGroups = GetObject("WinNT://" & strComputer & "")
colGroups.Filter = Array("group")
For Each objGroup In colGroups
'Wscript.Echo objGroup.Name
if objGroup.Name ="Administrators" then
For Each objUser in objGroup.Members
Wscript.Echo vbTab & objUser.Name
Next
end if

What do you mean? Are you looking for a tool that will do it or what? Most of the people here know how to write C++ code and that is why they might be able to do the work. What can you do and what do you want from the people in this forum?

How can i enumerate users
// adminGroup.cpp : Defines the entry point for the console application.
//
#pragma comment(lib,"Netapi32.lib")
#include <windows.h>
#include < LMCONS.H>
#include <lm.h>
#include <lmaccess.h>
#define MAX_PREFERRED_LENGTH ((DWORD) -1)
#include "stdafx.h"
int _tmain(int argc, _TCHAR* argv[])
{
NET_API_STATUS ret = 0 ;
LPCWSTR servername = NULL;
LPCWSTR groupname = L"Administrators";
LPBYTE buffer = NULL;
DWORD entriesRead;
DWORD totalEntries;
DWORD resumeHandle =0;
typedef struct _LOCALGROUP_MEMBERS_INFO_1 {
PSID lgrmi1_sid;
SID_NAME_USE lgrmi1_sidusage;
LPWSTR lgrmi1_name;
}LOCALGROUP_MEMBERS_INFO_1, *PLOCALGROUP_MEMBERS_INFO_1, *LPLOCALGROUP_MEMBERS_INFO_1;
//function call
ret=NetLocalGroupGetMembers (NULL, groupname, 1, &buffer, MAX_PREFERRED_LENGTH, &entriesRead, &totalEntries, &resumeHandle);
for(int i = 0;i< entriesRead ;i++)
{
//here i wan to enumerate but how
}
int n=0;
return 0;
}

I've never used that API but based on the documentation my first guess would be that if entriesRead is more than 1 the buffer will contain an array of them so you would iterate through the array, something like:
PLOCALGROUP_MEMBERS_INFO_1 pData = (PLOCALGROUP_MEMBERS_INFO_1)buffer;
for(int i = 0;i< entriesRead ;i++, pData++)
{
pData->lgrmi1_sid;
}
Of course I would have to verify that by debugging since I've never worked with it.
BTW: Don't forget to free the buffer 
"bufptr [out]
Pointer to the address that receives the return information structure. The format of this data depends on the value of the level parameter. This buffer is allocated by the system and must be freed using the NetApiBufferFree function. Note that you must free the buffer even if the function fails with ERROR_MORE_DATA."

Here what i get after a lot of googling or say binging
LPLOCALGROUP_MEMBERS_INFO_1 pstMembersInfo = 0;
DWORD entriesread = 0;
DWORD totalentries = 0;
if( 0 != NetLocalGroupGetMembers( NULL, _T("Administrators"), 1, (LPBYTE*)
&pstMembersInfo,MAX_PREFERRED_LENGTH,
&entriesread, &totalentries, 0 ))
{
AfxMessageBox( _T("NetLocalGroupGetMembers failed !"));
return ;
}
for( DWORD dwIdx =0; dwIdx < entriesread; dwIdx ++ )
{
AfxMessageBox( pstMembersInfo[dwIdx].lgrmi1_name );
}
NetApiBufferFree( pstMembersInfo );

That's pretty much equivalent to Mike's - it's just the casting's done slightly differently.

cout<< pData->lgrmi1_name <<std::endl; //how can i get name here as it is printing only address like below
printf("%S\n", pData->lgrmi1_name );;
