That's not the way to use a std::auto_ptr . Do like this:
std::auto_ptr<CBNoMessageBox_DBF_NTX> msgbox(new CBNoMessageBox_DBF_NTX(pszFileName));
msgbox->SomeMemberFunctionOfCBNoMessageBox_DBF_NTX();

does anybody know when should be release the auto pointer?
Normally - never, since the allocated memory is deleted by std::auto_ptr at scope exit. But if you must, then std::auto_ptr<>::release() is your friend.

There can be a good reason for this. Suppose the auto_ptr was declared as a class member and not initialized in the constructor of the class. I have done this from time to time.

The autopointer deletes its associated object when it goes out of scope automatically. To destroy it sooner, call reset().

Hey everyone. I am trying to find a method that will tell me (in an MFC Application) what the last modified time of a folder is. I can get this information fine for a file using CFile's status method, but unfortunately it does not work for folders. Any help would be really appreciated.

How about ReadDirectoryChanges ?! I don't know what type of application is it that you're dealing with but you can check ReadDirectoryChages out... it's defined in kernel32.dll

Why not?
CFileStatus stat;
CFile::GetStatus("C:\\Program Files", stat);
TRACE("%s\n", stat.m_atime.Format("%x"));
TRACE("%s\n", stat.m_ctime.Format("%x"));
TRACE("%s\n", stat.m_mtime.Format("%x"));

Hello Friends
I am having a dialog based MFC application in which I show internet browser using Microsoft WebBrowser ActiveX control.
Here I want to hid my mouse when I press some button like F3. For this I have used PreTranslateMessage() function and I am able to capture the F3 key press event. And on that event I have written code as SetCursor(NULL) and one boolean variable I m makingit false.
And then in MyDlg::OnSetCursor() function I m returing TRUE if that boolean variable is false. else returning normal
return CDialog::OnSetCursor(pWnd, nHitTest, message);
I am able to hide cursor if I remove Microsoft ActiveX control for Web Browser...What might be the reason and what should I need to do to hide mouse cursor..

Hi,
I am developing a MFC (VC++ 6.0) application which allows users to enter characters in certain editboxes in multiple languages (not multiple scripts in the same text) using IME (Input Method Editor). As a certain requirement I am required to determine a particular with a particular script e.g. Japanese with half katakana script so that the application can take a certain action based on it.
For achieving the above I am handling WM_INPUTLANGCHANGE and WM_INPUTLANGCHANGEREQUEST messages in a standard CWnd derived class's message map which contains visualActiveX (third party) components, I have generated the message handlers using class wizard and have made no modifications to it.
Now the problem I am facing is that the application sometimes successfully determines the changes in input language while fails at other time (no definate pattern here) which is obviously causing some functionality to fail at sometimes.
So what I am looking for is a fool proof way of determining the change in input language and then proceed further depending on the input language. If anyone knows a way to do it kindly let me know ASAP.
And just a point to ponder; could this be the case that sometimes the ActiveX component is eating up the windows messages i.e. passing them to it's default messaging processing since there are no handlers for the WM_INPUTLANGCHANGE and WM_INPUTLANGCHANGEREQUEST messages in the control and can this behavior be due to weired thread synchronisation problem
Thanks in Advance.

u need to convert your prog, to multithread cuz a library being used is multithreaded,
do like this,
in the Project Settings , select the 'C/C++' tab.
set ‘Use run-time library’ to either ‘Debug Multithreaded’ (for debug builds) or ‘Multithreaded’ (for release builds).
...and now somebody look into the previous thread...[yelling]

I'm using VC6 but I can't see the 'Use run-time library' in C/C++ tab under Project Settings.

Ok, I got it, thanx., But why does the error have to occur when my application is not multithreaded after all?

Im creating a multi-tabbed application, in which i constantly update status fields on all the pages, the problem being when i start up, some of the pages arent initialized or something, cause i get an assertion failure on my getDlgItem, How do i go about initializing all those tabbed pages, other than code clicking each tab?? I'm new to VC++ and .net, and I've been digging for awhile and cant come to a logical conclusion on how to do this.

Im using the following code to create and setup my pages
CMyPage MyPage
...
MyPage.Construct(IDD_MYPAGE_PROPERTY_PAGE);
...
AddPage(&MyPage);
Stated in the MSN docs, is that for another to work, the tab needs to be selected first, is there a way to bypass this option? Or a different way to construct the page so that it doesnt need to be clicked on?

Wow, that was quite the post. It has more information in it than many articles. It just may be worth it to take that post, add a working example, and post it as an article.

Thanks! Glad you liked. You know, making an article out of that post does sound like a good idea. I'll try to do it as soon as I finish a couple of things that are keeping me very busy these days.
Cheers,

Its definitly on the right track, but my situation is a little more unique. Im constantly getting real time data from a socket, and is needed to post the data all over my GUI, I guess I could create all the objects from all the pages and store them, like in your example, but seems like a lot of work, cause then when a tab is clicked, i need to override the clicktab button or something so that it adds it to the queue to be constantly updated.

Or did i completly misunderstand what that article was telling me?
