For each integer, if negatives, positives, and zero are valid data, there is no way to indicate if the integer should be used or ignored. Basically, an on/off switch to say ignore the integer at this index or data is valid at this index. The pointer can be used as the boolean flag. Valid pointer is "On", and NULL pointer is "Off".

OK. But this has nothing to do with my original point: sistematically allocating single integers (or, if you prefer, single boolean values) on the heap it is usually not (IMHO) a good idea. Dynamically memory allocation for built-in types is usually bad.

For each element created with new you need to call delete. Typically it looks like this: when you clear the list you iterate trough the list and call delete for each element in it and after that clear the list itself. Alternatively use a smart pointer[^] instead of a normal pointer -or- store elements instead of pointers (there is no need to store pointers in data containers).
Hope it helps.

Hi,
Can we have our application as _UNICODE supported as well _MBCS supported?
I am in middle of a robust project, where we are using some third party sources. if i set my project to _UNICODE supported then it forces all the places where i am handling strings are to be wchar, TCHAR etc.,
can i make the same in some files, since it forces to make changes in third party sources.
To make UNICODE Supported i made changes like "In Project settings in preprocessor definitions i just added _UNICODE.
Also set startup with wWinMainCRTStartup.
Qns:
Can i support both of them ? if so How ?
Thanks in advance.

You are free to mix types all you want. It's up to you to keep track of the settings and make sure you're
using the right character types in the right places, and converting where necessary.
I personally would go all unicode and use other character types only where required, but that's just me.

No it is not possible if you set your project _UNICODE in project settings, it will override _MBCS.
But i am here in position of converting a large project into UNICODE SUPPORTED.
Can i build that third party tool into a DLL and link them with my project ? Even though that also be defined _UNICODE.
Any Idea ? Get me out of this difficulty!. 
Thanks
Thanks a lot

Of course, but you need to understand how that affects your compilation.
Those are simply macros used with conditional compilation. The macros effect the
default char types in API function arguments and system structures. They also affect
the type of the tchar.h generic types like TCHAR.
You are still free to use specific types where necessary. For the affected Windows APIs,
you can call the specific APIs using the W and A suffixes where required. Same with Windows SDK
structures. In places where you need a specific char type, do NOT use the generic TCHAR - use the right type.
If you have third party code that requires a different character type then you need to deal with that by
converting your strings/char arrays to the correct type where necessary.

I'm dumping data in a listbox using a loop. I would like the listbox to display the data after each iteration as oppose to after the loop is over, how do I do that?

I'm new to mfc...can you give me a kick start? also, would using a different control be better?

Please detail your problem. For instance, if your need to represent a very large amount of data, a virtual list control [^] maybe an option.

If you do that in one single thread, the UI won't be able to process messages anymore (because the main thread is busy in your loop). This way, it will freeze and process the messages only when you exit the loop.
The way to solve this problem is either to create a worker thread that will send a message to the GUI each time a new item should be added in the list, or you can extract messages yourself from the queue and process them (GetMessage and DispatchMessage, see here[^] for some info).

Another option is after you add each string to the listbox, call the UpdateWindow:
m_pMyListBox->AddString(_T("Whatever string"));
m_pMyListBox->UpdateWindow();
The UpdateWindow bypasses the normal message loop, so you can update that way.
Hope that helps.

Karl,
UpdateWindow has solved my problem......
Thanks
How do I close this thread?

Glad I could be of assistance.
I don't know how you mark a thread as completed or resolved. Perhaps someone else knows.

Don't bother about, anyway you can modify the OP title (maybe adding [PROBLEM SOLVED] to the title).

You cna use of CListCtrl instead CListBox that is better.

Exactly how does that solve the problem?

I think listctl is bette than listbox and I think its better to try with listctrl so I said ctrl is better and its not direct his answer.

Hi All,
I have a question that has been bothering me for a while, I am trying to write an app that automatically enables ICS on a connection automatically. I have tried VBScript demos and I have written a C++ code for the COM interface. The problem is I can see the connection is shared in the Network Connection area but the other connections can not access it.
Weirder yet, if I manually disable the connection sharing on the connection I shared via right click -> properties then run my code again it does share the connection properly this time and my other interface can share with it. Any idea what I am missing here? It seems like the control panel applet does something else I am not doing. I also notice it sets the IP to 192.168.0.1 and gateway 255.255.255.0. I tried this manually but it didn't help my situation.
It also said in one of the VBScript http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=3148763&SiteID=1[^] I downloaded from Microsoft that 0 of my connections were private when it ran but when I did the enabling through the control panel it showed my main one I am sharing as public and the other as private. Could this be the problem? I can't find any documentation how to set this on the interface.
Thanks.

I came across an issue last night with CreateProcess.
I have a the following command line "foo > out.txt".
I I run this at the command prompt, foo dumps it's output to out.txt, all is OK.
If I try and pass this through to CreateProcess the output is NOT dumped to the file.
If I instead modify the command line to something like
"c:\windows\system32\cmd.exe /C foo > out.txt" and pass that to CreateProcess then I get the expected behavior. So why do I have to do this? Is there another way? I am using default parameters for most of the arguments.

AFAIK I/O redirection is performed by the command interpreter. CreateProcess cannot do that.
