The article refers to VC++ 6.1 and older. I am using VC++ .NET. I did not find OnInitialUpdate() function in the .NET Framework for CView, which they talk about in the article.
That's why I indicated it might only be remotely related.

I am not sure why this is relevent but anyways... to give you an idea I will tell u what my application is.
It is Like Windows Explorer. So left pane is the directory tree, but the right pane holds just the files of selected folder in directory tree (dont worry about the third pane I mentioned earlier). So it could be a little, or it could be a lot of files/items... but lets say it shouldn't be too much because this is just an assignment for school I am doing, not some program for Bill Gates

I really don't know of a reason to not do it the way I previously suggested, especially for the volume of items you've indicated. It's just a much smoother approach to a fairly common doc/view situation.
I'm curious why you are creating the list views each time they need updating. That's seems a bit inefficient. Why not create them once at the start of the application, and then update their contents as the need arises? With MFC, this is very easy to do using CSplitterWnd.

I made some small tests, it seems that delete[] can always replace delete, without errors.
But in my working project, it is not the case, I don't know why.

without errors, maybe ! but not without memory leaks !!!!!!!!

Some implementations might delete all memory, so you might not see any memory leak, but no implementation will call the destructor for every element in the array. If you have resources acquired by elements in the array, they won't get released until the program dies.

This is what I call "Programming by Behavior" and it is EVIL EVIL EVIL. You are ignoring the rules and just going by how the program appears to work in specific instances.
The C++ standard specifically states that delete [] and delete are not interchangeable. Doing so might work sometimes, but that doesn't mean it will always work.
If you have a class with a destructor, using delete will only invoke the destructor on the first element. Thus causing all sorts of problems if the class has a non-trivial destructor.
NEVER EVER interchange delete with delete []. It is just wrong.

I'm going to patent thought. I have yet to see any prior art.

p is a pointer to an array, when running, the 1 fragment is ok, the 2 one is wrong. What's the reason?
//in the destructor
//1
if (p!=NULL) {
for (int i=0;i

Here are a few new/delete pairs:
int *n = new int;
delete n;
int *n = new int[5];
delete [] n;
char (*p)[10] = new char[6][10];
delete [] p;
char **p = new char*[3];
p[0] = new char [6];
p[1] = new char [6];
p[2] = new char [5];
delete [] p[2];
delete [] p[1];
delete [] p[0];
delete [] p;

If p is pointing to a single variable then the normal delete is fine but in case of an array pointer it should be deleted using delete []p;

Afther a long search over the internet and MSDN, I decided to ask someone more skilled than me that may be on this forum...
Is there possible to intercept an application file operation reqest? Let's say an application is triing to open a file, can I set a hook that notifies me that?
If not, how can this goal be accomplished? Writing kernel mode intermediate drivers for the i/o routines?
I hope I understand...because is a rough world out there...

Thanks for you answer, but I'm tring to find a way in order to intercept some file I/O actions...
Adica in timp dinamc sa imi spuna daca o aplicatie deschide o fila, citeste dintr-o fila, scrie intr-o fila, etc... Intrebarea era daca este posibli cu Hook-uri si cum, sau daca nu cum este posibil? - Mersi oricum 
I hope you understand...because is a rough world out there...

It's possible and, depending on your actual requirements, might not be a trivial task. You may need to create a virtual device driver, install a VxD service called IFSMGR_InstallFileSystemApiHook, or create a file system driver that "sees" all IRPs and FastIO requests directed at a drive.

Hello,
I am using MFC to call a stored procedure written in Oracle PL/SQL, but when I make
the call I get the next error in Spanish:
"No se enlazaron columnas antes de llamar a SQLFetchScroll o
SQLExtendedFetch", which more or less in English means:
"No rows were binded before calling SQLFetchScroll or SQLExtendedFetch".
I am using a CRecordset derived class to access the stored procedure. I am
unable to find the error.
THE STORED PROCEDURE'S HEADER:

Hello there.
I'm having difficulties on how I will add the data from one or several CStringArray to another CStringArray.
For e.g.
CStringArray strInfo[1] = { "12", "13", "14" };
CStringArray strInfo[2] = { "1", "2", "3", "4" };
CStringArray strInfo[3] = { "5", "6", "7", "8", "9", .... };
.
.
.
. and so on...
and the new CStringArray should have the data from strInfo[1], strInfo[2] and strInfo[3] ....
so it should be like this.
newStrInfo = { "12", "13", "14", "1", "2", "3", "4", "5", "6", "7", "8", "9", .... };
Please help me on this matter. Any help is much appreciated.
By the way, if it's possible to convert it in an integer array, please teach me too.
I also made the input data as integer array instead of CStringArray (int* strInfo[1], int* strInfo[2], int* strInfo[3]...) but still I can't pass the data into another data array.
Thanks and best regards.
With great power comes a great responsibility.

use this
details in MSDN, it`s a member of CStringArray
void InsertAt( int nStartIndex, CObArray* pNewArray );
CODE:
CStringArray strInfo1;
CStringArray strInfo2;
CStringArray newStr;
strInfo1.Add("TEST 1->1");
strInfo1.Add("TEST 1->2");
strInfo1.Add("TEST 1->3");
strInfo1.Add("TEST 1->4");
strInfo1.Add("TEST 1->5");
strInfo2.Add("TEST 2->1");
strInfo2.Add("TEST 2->2");
strInfo2.Add("TEST 2->3");
strInfo2.Add("TEST 2->4");
strInfo2.Add("TEST 2->5");
newStr.InsertAt( 0, &strInfo1);
newStr.InsertAt( strInfo1.GetSize(), &strInfo2);
for( int i=0; i

You can use CUIntArray instead of CStringArray, provided that you are using unsigned ints (==positive values).
Or, you can save your values as unsigned inte, and then (if you have to) cast them to signed ints.
Pseudo-code (should work, not tested):
for(i = 1; i < noOfArrays; i++)
{
for(j= 0; j < intInfo[i].GetSize(); j++)
newArray.Add(intInfo[i].GetAt(j));
}

Thanks for your help guys.
I found the Append function under CStringArray. I'll try to use it first, if this will not give the result I needed, I will try your solutions guys..
Thanks for the responds..
