Hi,
You can use GetFileAttributesEx -> if dwFileAttributes from WIN32_FILE_ATTRIBUTE_DATA struct will have FILE_ATTRIBUTE_DIRECTORY - so it's directory

hi,
try CPath::IsDirectory(). But it is an ATL class. You have to include atlpath.h

No, there is no difference, NULL is defined as 0.
It's just that using NULL for a pointer is more convenient (to make the difference with the 0 value).

Hi
No difference between NULL & 0
In VC header file NULL is defined as 0

There isn't sintax difference, look at the macro:
#define NULL 0
but there is a logical difference:
pointers doesn't contains numbers but addresses, so p=0 is logically incorrect, it must be set to the default null address(NULL). That, of course, for convention and semplicity it is set to 0.
Using NULL is only a way to write more readable code.

In C++, nothing. In C, lots. A standard C compiler won't automatically convert 0 to a pointer, so you'll have to assign (void*)0. In C, NULL is defined as ((void*)0) to allow you to set a pointer to 0. In C++, the compiler will happily convert 0 to a pointer, so you don't need the cast, and NULL is simply defined as 0.

Hi ,
i m trying to create an scrollbar as an activeX component which resizes itself based on image it is attached .
Please reply ASAP
suren

We are using a CComboBoxEx with style set to droplist to display a lsit of images.
When the drop down list appears and we click on the combobox (not on the drop down arrow),
the dropdown list closes as expected but then it immediately reopens!
How to prevent this behavior?
If instead we click on the drop down arrow when the list is open it decently closes without reopening.

Hi All,
I have an owner-drawn list box.
now my task is to fit a scroll bar for that.
when im trying to get the scroll position using CLisbox::GetScrollPos, it is always returning 0. how we can determine the current scroll position?
Currently im scrolling teh items by sending SendMessage(WM_VSCROLL,MAKEWPARAM(SB_LINEUP,0),0); function. will this update the current scroll position. in a normal list box im exactly getting the scroll position, but with owner-drawn one, im not getting.
anyone can suggest a solution for this problem? I need to draw the scrollbar as the part of lisbox not as a seperate control.
now tracking teh thumb is the main issue. pls help me to come out from this.

How to check if a url is valid at internet?

Does this, certainly cannot examine a webpage whether exists? Only analyzes a URL.

Are you wanting to validate the URL itself, or the actual Web site? If the latter, try InternetCheckConnection() or IsDestinationReachable().

I was using UDP protocol(SOCK_DATAGRAM) to do the network communication.
I used 'sendto ' system call to send data . After sending data repeatedly using 'sendto' system call it failed at one point.
Using WSAGetLastError I could retrieve the error code as 10055 which means --
No buffer space available.
An operation on a socket could not be performed because the system lacked sufficient buffer space or because a queue was full.
Can anyone suggest me how to overcome this problem.
