You probably need something like the following:
(Sample for a 3-items array)

auto_ptr<Foo> pi[3]={auto_ptr<Foo>(new Foo), auto_ptr<Foo>(new Foo), auto_ptr<Foo>(new Foo)};

If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

Thanks CPallini,

Do we have any ways to saving typing?

George

Yes: employ someone and let he/she do the job for you.

Thanks CPallini,

I believe it is a limitation for initialization approach for auto_ptr array. Smile | :)

That applies to all arrays initialization. Actually I dont know if there is a smarter way to do it.

No CPallini,

For a normal array, we can declare/initialize in the simple way, saving type work. Right?

int array[20] = {100}; // initialize at the same time, assign all elements to 100

George

CPallini1-Apr-08 23:49

No George. You are wrong. Your code

int array[20] = {100};

initializes only the first element of the array (please make a test).
You can indeed apply the same syntax to an auto_ptr array.

Cool, CPallini!

I have tried, you are correct!

Use Boost's scoped_array[^].

Good resource, Steve!

Unfortunately, in current project, I have to use MSVC, and it does not support shared_ptr. Smile | :)

As you have already discovered auto_ptr is not designed to work as an array of pointers. There are multiple solutions to your problem and they are described in the below links.

http://www.codeproject.com/KB/cpp/COAP.aspx[^]

http://www.gotw.ca/gotw/042.htm[^]

If you are just interested finding out how auto_ptr can be used with an array then above links are suffice.
but in real use, you might want to take a look at the boost smart pointer library. you can also use the shared_ptr as it is designed to work with STL containers.

Re: Internationalization -

Hi Ankita,

I have not made myself understood. My question is (say in another way), how to define an array of auto_ptr and initialization at the same time of definition? Any ideas?

George

Hi

I have created a ocx control in vc++.
The control is used in ASP.net.

Now the project is modified for Internationalization.

So I have to change the tooltips and other text.
for that what modification i need to do?

I think, I can expose property for each string.
then whatever the value in that property will get displayed.

can someone suggest whether my assumption is correct or not?

A Question about FindWindowEx

Hi,
Here is the code.

HWND hwndCalc;<br />
	hwndCalc = ::FindWindowEx(NULL, NULL, _T("SciCalc"),_T("")); <br />
	DWORD dwerr = GetLastError(); // dwErr = 0(successful) but unable to understand why hwndCalc is NULL i.e. 0x00000000

I'm unable to understand why FindWindowEx is returning null handle although GetLastError() is returning 0 i.e. successful
Please check the document of FindWindowEx

Because FindWindowEx is successfully finding no window matching your criteria?

You're looking for any window that is a child of the desktop, with a window class name of SciCalc.

It's worth verifying using spy++ that that is actually true. Or is the window text for that window scicalc, and the class is some other name?

(and just to be clear, this is class as in RegisterClass, not as in class CMyWindow...)

Iain.

Thanks for the quick reply.

I don't think so, if this happens then GetLastError() function returns 2(The system cannot find the file specified.)

Yes exactly and that window is "Calculator window".

Iain Clarke wrote:

I have verified that "Calculator window" is a child of desktop window in spy++.

I just ran calculator, and use the following code snippet:

HWND hWndFind = FindWindowEx (NULL, NULL, _T("SciCalc"), NULL);

if (hWndFind)
{
    TCHAR buf [1001];
    ::GetWindowText (hWndFind, buf, 1000);


}

and it worked a treat. The text said "Calculator" as expected. So I'm not sure what's wrong for you.

Do you have multiple monitors? I'd doubt this should be a problem, but I'm stabbing in the dark now. Terminal services? Other user logged on? Etc.

I did my test under XP.

Iain.

Nothing of the above.
He simply has _T("") as last parameter.

OT: Iain cautious approach...

Thank you very much.
I got the point; actually I was passing incorrect value for 4th parameter of FindWindowEx function.
Again thanks a lot. Smile | :)
