Sorry, may be I am getting confused  In your definition of create2() you reset p, by p = 0. So in each call to create2() p should be set to 0 before being incremented. So wouldnt you therefore expect the same value printed everytime?

Actually I just answered my own question
The static int p = 0 only gets called once at instantiation which makes sense coz otherwise you will have loads of p's around which goes against the idea of it being static (only 1 copy of the variable exists).
Well I hope that is correct.

Sorry for the delay. It's due to the fact I went home from work yesterday. 
That's right, a static variable just gets initialized once.
Besides, there are just one copy of it, in the heap.
The fact that it is stored in the heap (as opposite to the stack), makes it protected from alterations.
So if you want to make sure (as in this case) that a value, returned from a function will contain the same value, static is the way to go.
This goes for plain C. For C++, a class member variable does the same.

Hello
Are you sure that static members are on the heap? That would imply they are dynamically allocated would'nt it? Also if you have an item on the heap you would need to use 'delete' at some point for clean up. If you can send me a reference for this I would be most interested.
Thanks !

Sorry, I was wrong about this, it seems.
The most common place to store static variabels seems to be in the data segment of the program.
Sorry. 
But the rest is true!

I did a google on 'static heap C++ allocation'. It seems on some systems its on the heap and others on the stack. But it is allocated at run time.

Nope. Not on the heap.

Add the following to your test:
void effect( void )
{
int change = 1;
}
int main( )
{
int *p;
p = create();
effect();
cout ...
...
}
...cmk

How about using GetWindowText()?
Somethings seem HARD to do, until we know how to do them.

sure it's possible... everything's possible in C++.
CString strCaption = _T("");
CButton* pMyButton = NULL;
pMyButton = (CButton*)GetDlgItem(IDC_MY_BUTTON);
pMyButton->GetWindowText(strCaption);

I m fine too !
I hope that there is nothing wrong with you
thank's

What does _T mean in your code:
CString strCaption = _T("");
How would the following differ?
CString strCaption = "";
Thanks

it means that in ANSI, the string will be seen as "" (const char*), but in UNICODE, the string will be seen as L"" (const wchar_t*).

I know you already have the answer to your question, which is nice.
You really need to have a better title for your post than "o".
If someone hadn't already replied, I'd have ignored your message completely.

I'm really sorry i didn't mean it because I left the title to
the end and then i hit the bouton post message without checking out
I forget it
sorry !

iam looking for ways to convert an ActiveX DLL created with MFC into an MFC executable application. Wanted to know the various settings changes that needs to be done in visual studio project settings. How to change the entry point function from DLLMain() to that of an WinMain()?
Thanks and Regards,
Pradeep

An activeX is contained in an application that interracts with it. If you have a standalone ActiveX, that's useless. Take for example the grid control: what's the purpose of having a 'standalone' grid that does nothing, except that you are able to write things in the cells ?
Why do you want to do such a thing anyway ?

Hi,
Thanks for ur reply.It is nice,but i want to change the view with in the same splitter pane in which i have the tree control.I want to change the rest of the view except the tree control i.e, the tree control remains fixed at the same place and different buttons related to each selected tree item should be displayed.As a whole switching views with in a splitter pane consisting of tree control.
Thanks.

I have a somewhat similar situation in that the right side of the view is actually a property sheet control (tree control fixed on the left) and I use the tree control to display different 'pages' of the property sheet. When a tree item is selected I simply call a SwitchPage rotuine to display the proper page. The property sheet doesn't display tabs or anything goofy so it is somewhat transparent to the user that the seperate views are actually property pages
hope this helps
