I'll go back and re-read my copy to make sure. The reason I ask is because Sutter (along with Meyers) usually write about platform independent coding styles, so it would be unlike him to mention something specifically about DLLs. Especially since the same limitations are not placed on .so's in the *Nix world.

I think you'll find it in the item 63. Use sufficiently portable types in a module’s interface. or somewhere around it in the Namespaces and Modules part of the book.

Hi,
Recently I started working in VS2005 instead of VS6.
In VS6 I could add member veriables to my class by using the class wizard.
In VS2005 I'm able to add only one member veriable at a time(i.e - for each
member veriable i need to right click over the form , choose the Add veriable , add the member veriable and choose the finish option(I can't add more than one veriable in one session).
Is there another quick way to do so?
Regards,
Eli

Open the class' .h file and start typing. It's the fastest and easiest way to add member variables.
You may be right
I may be crazy

When you click the class in class sheet, you'll see a property sheet. It is like the class wizard for adding message handlers and overwriting virtual functions.
If you use Dialog DDV/DDX, the adding variable members is for it.

I am about to have a go at writing my own service application. But before I start, I have a few questions I have unable to find reasonable answers to.
An article on CP states that a service is loaded at boot time before any users log on to the system. The service I intend to create is dependant on some system variables to be set which means the user is required to be logged on. This leads me to my question. Since the service requires the user to be logged on, I also want to be able to configure it for each user, which would probably require reading some HKCU registry keys. But how should I handle the case where more than one user is logged on, would the service be run as a seperate instance?
When installing the service, is it possible to do so without admin privlages?

The service runs in the context of a user so HKCU registry keys are of little/no help.
Running as a separate instance I don't think is possible.
Is there a way you can communicate with the service when a user logs on and send it the variables
it needs?
Otherwise, it sounds more like an app that runs in the background from the users Startup folder situation.

Hi,
I'm currently writing a small server application for data transfer. Two commands are for direct file transfer (relative path, e.g. test/data.dat) and I want to limit the filenames to be in the directory and subdirectories of the server application.
Let's say the server lies in c:\server\server.exe, now I want to be able to e.g. put a file into c:\server\new folder\test.dat, but not outside the server directoy, e.g. c:\test.dat (e.g. with a ../test.dat or new folder/../../test.dat).
Is there a good way to parse bad filenames/path?
Greetings

It is not clear what you need to do. I don't know what a "bad filenames/path" is. I am not sure if you must recognize incorrect syntax of if you need to allow access to something and not allow access to other things.
File access is typically controlled using the built-in features of the NTFS.

Per your subject, you need to read up on Access Control List (ACL). There's a whole API for it.

One way, if youv'e got absolute paths, just compare them as strings/char arrays.
You can get absolute paths by using _fullpath() or _wfullpath.
Then you can do the compare, something like this (beware! Old C syntax here):
NOTE! I didn't find the time to set current directory to c:\server before testing the code, so I made a full path name for goodRelPath. Else, I could have used a relative path for goodRelPath.
char * projectDir = "c:\\server\\";
char * goodRelPath = "c:\\server\\new folder\\test.dat";
char * badRelPath = "c:\\test.dat";
char tempFullPath[MAX_PATH];
_fullpath(tempFullPath, badRelPath, MAX_PATH );
if(strstr(tempFullPath, projectDir) == projectDir)
{
}
else {
}
_fullpath(tempFullPath, goodRelPath, MAX_PATH );
if(strstr(tempFullPath, projectDir) == projectDir)
{
}
else {
}

Thank you for your help and the example. Great

I'm glad to be able to help you.
I have a faint memory of using this technique in a program system in the past (15 years ago, or even longer). It was in the DOS days, and there was a DOS call to convert a relative path to a canonical path name.
Well, the principle worked then, and should do so today.
Good luck.

Can you spend a little more time thinking about what you need to ask?

There is at least one thread for any application, MFC or otherwise.

Hello folks,
I want to search all of files under some directory. For example, dir\file1.txt,
dir\file2.txt,
dir\file3.txt,
...
When using ::FindFirstFile and FindNextFile, I can get all files, and then I can process them. But because the processing may last long, I want to use multithread, but There are strage errors. Can ::FindFirstFile/FindNextFile be multithread? or Are they thread safe?
Thanks in advance.

Yes they can, but don't make changes to the directory structure because they may fail. In your case I would use a thread to get the subdirectories only, then launch another thread to process the files in the directory ( you may want to take a look at thread pooling to do this ). Be very careful about where you are writing your results. Your problem sounds to me like two threads trying to write to the same location.

Each time when the program find a file, it send it to the file_handler() to process. The file_handler() is a function in where I create another thread to process the file. It is like this:
void CMyDoc1::file_handler(LPCTSRT pFileName)<br />
{<br />
m_fileName = pFileName;<br />
AfxBeginThread(ThreadProc, this);<br />
}<br />
UINT ThreadProc(PVOID pParam)<br />
{<br />
CMyDoc1* pDoc = pParam;<br />
pDoc ->FileProcessor();<br />
return 0;<br />
}
The error occurs in FileProcessor(), when free the memory.
