I have a list of domains users( ie domain\user1, domain\user2, etc.. ), and I want to share a folder for this users only.
i am tried with NetShareAdd(). and succeed to share with everyone Read permission. But I do not want to give everyone ,really want to specify the users
This is the Code block i have tried.
#define MAXLEN 256
NET_API_STATUS res;
SHARE_INFO_502 p;
DWORD parm_err = 0;
char *dir="TESTSHARE";
wchar_t shareName[MAXLEN];
mbstowcs( shareName, dir, MAXLEN );
char* remark = "TESTSHARE to test NetShareAdd";
wchar_t ShareRemark[MAXLEN];
mbstowcs( ShareRemark, remark, MAXLEN );
p.shi502_passwd = NULL;
p.shi502_permissions = ACCESS_READ;
p.shi502_netname = LPSTR(shareName);
p.shi502_type = STYPE_DISKTREE;
p.shi502_remark = LPSTR(ShareRemark);
p.shi502_max_uses = 4;
p.shi502_current_uses = 0;
res = NetShareAdd(NULL, 502, (LPBYTE) &p, &parm_err);
can Anyone one help me..
Thanks in advance

Hi
I need help creating a user interface which would display all the certificates stored in MyStore. I want to display certificate information such as Issued by, issued to, and expiry date in different columns and when i click a specific certificate, the certificate should open up. I was able to display all those information in the console but I don't know how to go on about doing this in a GUI. Help would be most appreciated

why dont you look at using a dialog and a listbox (ie, for columns) ?
there's plenty of examples of using a listbox

will do. thanks

The 32-bit "Interlocked...." functions say that their parameters must be aligned on "a 32-bit boundary," otherwise they behave unpredictably.
Do I need to worry about this in the ordinary case of declaring member variables in my C++ classes with VS 2008?

If you don't use #pragma pack and change the alignment to less than 4, you don't need to worry.

Thanks! I was getting worried there for a while.

My task is as follows...
I have 2 data files a Source (A) and a Destination (B) both located in the shared network drive.
A is a data file (plain text) between 2GB and 3GB made up of records of fixed size.
A is always being written into by other processes (new records being appended at the end).
I would like to read through the whole file A, read each record, leave what I still need and archive the rest to B.
There is a 10 character string I can use within each record as a filter.
Any tips how to go about this? Is MMF the path to take?
Thanks for any help.

Read it in in chunks. fopen() does that for you, but you could optimize the processing by doing it yourself. Since you are using fixed size records, this is even easier to code.
MMF is definitely NOT the way you want to do this for several reasons include the size of the file and that it's on a network resource.

actually, i am using MMF for this reason (the size of the file). With MMF, I can specify in MapViewOfFile which part of the file to load, instead of opening the file the usual way which loads the whole file in memory. Also, I can just write to the file via the mapped region of memory directly. This would be tricky in the usual way as I have to remove records in place (meaning if a record does not fit the filter, i have to write in its place the next record that does.)

Since you are reading sections of the file sequentially, memory mapped files offer zero benefit. Since shifting the window of the memory mapping requires operations, you are making the program slower for no reason. I fail to see how this is tricky using multiple buffers and straight I/O.

maybe i'm missing something but it is mainly for the operations i am performing to file A which is large.
say, i partition file A in blocks of 64kb. i read block1 and filter those records i am not interested in. i write back to this same block1 those i want to keep. when i am finished with this block, i move to the next block2. i may still be not done writing to block1 because i will always be interested in less than or equal records to the original.
therefore i have 2 mapviews of fileA, view1 is just reading which is always the same or advanced in the file as view2 which writes back.
the other point i think MMF is useful is the fact the file is too large as to load entirely in memory via the usual file open operations. i hope i make sense to you? do you still think i could do this same as or better with usual fopen?

I understand what you're doing and still wonder why you don't just use CreateFile() and two buffers?

I've finished my small program as I described. Out of curiosity, how do you suggest I do it using CreateFile and 2 buffers? Thanks.

Use CreateFile() to open the file. Allocate a read and write buffer that are multiples of the record size. Each buffer would have an associated offset. Start reading records. Once you find records to be extracted, set the second buffer to that offset and start copying records into it as needed and flushing it when required.

You can use ReadDirectoryChanges WIN 32 API, which registers for file changes in a directory, and use GetQueuedCompletionStatus function to wait for the changes. So when ever new records get added to A you will get notification of the changes, and read the added record and archive it to B.
You can store a pointer on where you are in the file (like the number of bytes read) and continue from it when the next change arrive so that you don't have to read the whole file every time a change occurs.
If you want to delete contents from the file though you will need some kind of process synchronization to avoid simultaneous write.

I have a linux application, that i want to use to find and manually read/edit the windows Vista/7 BCD file. I cannot run any existing win32 applications, I need to hard code one in C/C++
Please help
Thank You

My problem is that the windows Boot Configuration Data is a binary file, which cannot be accesses directly, and since my working environment is Linux, I cannot use any Microsoft released code or any third party windows application
So where can I find information on how to read and modify the windows BCD using linux (like how is this file structured etc.)
Thanks a lot

You could try using CRT code to read from the c:\boot\bcd file. If Windows is up and running, however, it my have that file opened/locked exclusively.

I'm sorry, I'm not familiar with "CRT code" could you also please suggest some resource where I can find out about this?

Hello,
I'm a developer and one of my faved languages is C++. Now I've been coding a lot with Visual Studio and I can do lot's of things with C++. Time to time I get interested in Linux projects, Opensource libraries and other stuff. So I tried to use Eclipse in various ways to work out my C++ stuff, but I get so much in trouble that I give up before even writing a few lines of code. The problem is that I get confused with using Eclipse CDT, the Linux handles libraries and dependency nightmares. For example, I install a library, say Libxml++ (which is a c++ wrapper for libxml). Now apt (using ubuntu) will install it in /usr/include/libxml++-2.6/libxml++ . The include files then get nervous as they reference simply <libxml++ stuff.h="">. So GCC, and it will complain with errors. Now this is the usual kind of problem I get in when I try to do such things. And I end up posting to forums, getting a reply days later, solving the problem in an impossible to know way, while in the meantime I lost any interest in what I wanted to do and I just don't go on with it anymore. Now as it is the nth time I get into this, I ask: is it so complicated or is it just that I miss some reading, some special reference???? Is it possible that on visual studio you can code thinking about code, while on linux you have to spend so much time in setting up the environment??? I'd be really interested in using OSS software and libs, or even partecipating to projects, but it is so difficult to get in. So, what are your suggestions? What should I read, do, experience?

When you install Visual Studio, you are installing a lot of libraries for working with the OS and a lot of associated libraries. But if you install any other third-party libraries (like libxml++, for example), then you'll go through similar pain as with Linux development.
You either need to set environment variables to tell GCC where to find header and library files[^], or specify those directories as suitable GCC options in your makefile (or project file, if that's what Eclipse CDT uses).
For example - I program on Mac OS X (which is Unix underneath the GUI). I have the following environment variables defined to find Boost and the libraries I've installed with MacPorts (equivalent to Ubuntu's apt-get):
CPLUS_INCLUDE_PATH=/usr/local/include/boost-1_38/boost/tr1/tr1/:/usr/local/include/boost-1_38/:/opt/local/include:
LIBRARY_PATH=/usr/local/lib/:/opt/local/lib:
So, I've just added libxml++ (or libxmlxx as MacPorts calls it):
sudo port install libxmlxx
---> Fetching libxmlxx
---> Attempting to fetch libxml++-1.0.5.tar.bz2 from ftp:
---> Attempting to fetch libxml++-1.0.5.tar.bz2 from ftp:
---> Attempting to fetch libxml++-1.0.5.tar.bz2 from http:
---> Verifying checksum(s) for libxmlxx
---> Extracting libxmlxx
---> Configuring libxmlxx
---> Building libxmlxx
---> Staging libxmlxx into destroot
---> Installing libxmlxx @1.0.5_0
---> Activating libxmlxx @1.0.5_0
---> Cleaning libxmlxx
I know port installs into /opt/local. Sure enough, in /opt/local/include, I see a directory for libxml++-1.0. I now know that to use libxml++, I can add /opt/local/include/libxml++-1.0/ to CPLUS_INCLUDE_PATH or (and this is more likely) I can add the option -I/opt/local/include/libxml++-1.0/ to the gcc command-line.
g++ -c -O2 -I/opt/local/include/libxml++-1.0/ program-that-uses-libxml++.CC
If you use a makefile, then add -I/opt/local/include/libxml++-1.0/ to the CXXFLAGS make variable:
CXXFLAGS += -I/opt/local/include/libxml++-1.0/
That will add the include folder option to the gcc command line only when compiling C++ files.
HTH!
