Perform cleanup correctly (i.e. you really need to be more specific).

I've found the best way is to make sure I destroy any resources
that I've acquired when they are no longer needed.
Trust me on this one....it works.

Hello Mr. Mark,
I've destroyed my PS3 after I finished playing burnout on it, since I no longer needed it today. I then burnt my refrigerator after I took out all the beer. I'm 'working up' on the air conditioner with a hammer now. But the memory leakage still exists. Please help me with further course of action.

When I read part of your post in the response email, I thought it was from the OP.
I was thinking, oh no, this guy's falling apart hehe.

And I'm saying, what's the (compiler) problem?

You need to reply "better" than that.
If you can't be bothered giving him a sensible reply, don't expect him to help.
As we're not psychic... how do you "know" it's not working?
Does the compiler crash?
Does it give a message?
Does it claim to succeed, but you can't run the compiled program.
Those are just off the top of my head - I'm sure there are other details you can provide if getting help is at all important to you.

Did the program ran in Vista?
If not, why?. What error happened?.
Please, give more information about it.

Why you need to compile the DLL again?.
If it runs in XP usually should run in Vista.
However, if you are trying to compile the the DLL and you can't, will help a lot, the messages the compiler throws to understand why. We can't guessing what problem you have.

In C++ i am creating a mutex to guard the writing to a file.
I have 4 threads that call a method in a .dll. The method in that dll, will write to a file when needed. I have a questions surrounding the mutex. First off :
1. Do i use CreateMutex or OpenMutex
2. If i use CreateMutex, can someone guide me on where to find the
attribute list for the 1st parameter.
3. On both Create and Open Murtex, the last parameter 'LPCSTR' is supposed
to be a name of the mutex. Can i just create any name? Should it
be a GUID?
Thanks in advance

If you want only intraprocess synchronisation, IMHO then go for CriticalSection, and don't bother about the Mutex questions.

I used this same concept for writing to another file and had no issues.
Here is what i do:
HANDLE hmutex = OpenMutex(MUTEX_ALL_ACCESS. FALSE, TEXT("2354fg-45gefgg"));
if (NULL != hMUTEX)
{
WaitforSingleObject(hMutex, INFINITE);
Begin writing to file
}
ReleaseMutex(hMutex);
CloseHandle(hMutex);
Looks like the mutex returns null so i never get to write to my file.
Maybe there is something wrong with the name(third parameter)??

OpenMutex get the mutex Handle for an existing mutex. You must have a Mutex Created with CreateMutex. what about Critical section?

LCI wrote: 1. Do i use CreateMutex or OpenMutex
In the thread initializations, use CreateMutex(). If the mutex already exists then you'll get a
handle to it and GetLastError() returns ERROR_ALREADY_EXISTS. If it's a new mutex you'll still get
a handle to it.
As others have mentioned, you don't need a named mutex if your threads are all in the same process -
which includes your DLL.

Windows security is beyond the scope of this board, but there is documentation[^]
Pass NULL if in doubt.

You can use a GUID (converted to a character string). Any unique string.
But again, no need for a named mutex if you only have one process - you can use a critical section instead.
