I suspect that the original poster wishes prevent the file from showing up in list of files in a directory.
You can set the FILE_ATTRIBUTE_HIDDEN, which is the accepted method.
However, if someone uses Windows Explorer with the "Show Hidden files, folders, and drives" open turned on (non-default setting), then hidden files are shown.
The original poster is saying "Screw you end user, I don't care that you want to see hidden files, I want to keep my hidden files really hidden!"
In that case, use the combination of FILE_ATTRIBUTE_HIDDEN along with FILE_ATTRIBUTE_SYSTEM to hide the flie even more so.
Of course, one has to wonder why an application must go to such lengths to prevent determined end users from seeing what files are on their file system.

Which is broadly what I told him/her. However the OP has still not explained clearly what the problem is. Just saying "the file is visible" tells us nothing; a common problem on these forums.

check it this utility which does not make any system file just make invisible in the explorer from the user i dont know how he is doing once we hide the folder again it does not allow to create the same name of another folder please help me out from this ..............
i am not looking for the
configure the items Windows Explorer suppresses from the list from the Folder Options control panel. You can even choose to show Hidden items and “protected operating system files” (known internally as “Super-Hidden,” as if they had a giant H printed on their shirts).
i am already done this hiding the folder by changing its attribute like (+H,+S) by cmd prompt and by setting the properties of it ...
totally am not looking for this trying to make folder invisible from the user ....
please reply fast .....

Thank you for the additional details, and explaination of what you have tried already.
While I can't be 100% certain, it appears that Folder Lock is software that runs on your machine all the time. It probably (but again I'm not certain) installs a file system filter that monitors access to files/folders it manages. It can then choose whether or not to show you the file/folder.
Here is more information on File System Filters:
File System Filter Driver Tutorial[^]
Now, the file/folder isn't truly hidden - it's just that a piece of software intercepts the access and blocks it. If the software isn't running, then the file is available to all.
If your requirement is to make a file hidden from view without software running all the time, then investigate the NTFS list permissions.

Hi!
I've done multi-language support for my application. It displays characters other than Chinese,Japanese and Korean. What to do display these characters? Is there any other way than installing the language packs? I don't want to install the language packs.

Why? If you need to display a certain language's characters then use the tools that are available. The alternative is to write your own character/font generator.

Will the installation of Fonts for these languages be suffice? I don't know which fonts needed for each of these languages(Chinese_Traditional,Chinese_Simplified,Korean and Japanese).

Here[^] are some links to Microsoft support for these character sets.

My xp system is the English version. but it can support Chinese Japanese, Korean after install East-Asia language package of Microsoft.

The easiest way to handle this is to change the font to Aerial Unicode MS. This font is installed n all machines that have office or some office app, like Excel or Word. Its not a Guarantee for all machines. For the other you need to install some other Unicode font.
You can do this by Changing the font properties on the main dialog box.

After this statement
status = NtQuerySystemInformation(SystemHandleInformation,handleInfo,size,&needed);
the count is
handleInfo->HandleCount=39337 Your code then goes on to examine each of the handles to check if it belongs to the PID. After finding 26 handles, your code crashes in malloc with ENOMEM. As far as I can tell, up until then the buffer objectTypeInfo->Name.Buffer contains valid strings. So the good news is, your code seems to be working.
Maybe you could search for the specific APIs you're using, and check if you're calling them correctly? It looks like you're not freeing some memory buffer.

The majority of MFC class methods have equivalents in Win32; check the documentation on MSDN for any extra parameters needed. The CDC and CBitmap objects would be replaced by HDC and HBITMAP handles. It is simply a matter of reading the documentation and modifying the code according to the correct rules.
