One more question about this topic.
Where and how should the pointer 'objMyClass' be deleted to prevent memory leak. I think this should be done at the end of SubFunc(). However, I am not very sure.

Any time after the pObject->SubFunc() call (obviously) 
There's alot of people who object to deleting objects in a different thread than the thread the
object was created in. If you are using new/delete this is perfectly legal to do, so IMO it
comes down to preference.
If it's clear in the code that you create an object (using new) and send it off to a worker
thread to be processed, and that the worker thread will delete it when it's finished, then delete
it in the thread proc when you're finished with it.
If you want to delete it in the same thread it was created in (the UI thread in your example)
then you could use PostThreadMessage() from the worker thread to send the pointer back to the UI
thread for deletion when it's finished with it. The worker thread would need to know which thread
it came from to know where to post the message to.

I personally wouldn't do it IN the SubFunc() function. That would be, IMO, too buried to be clear
in the code what's going on. Right after the pObject->SubFunc() call a "delete pObject;" would
be fine.
I would just make sure to document it well in the code with comments so when you possibly enhance
the code later you know exactly where objects are bing deleted, something like this:
void CHhhhView::OnButton1()
{
MyClass *objMyClass = new MyClass;
AfxBeginThread(MyThreadProc, objMyClass);
}
Whatever it takes to make sure you always know that you shouldn't use objMyClass later because
at any time the worker thread will delete it

Thank you Mark for your clear explanation.
One more further question, also about mem leak. i have some dynamically allocated variables (using malloc(), new) in SunFunc(). I wonder if those allocated mem can be deallocated automatically after the thread finished successfully. Or, i have to take care of the memory releasing things myself.
Moreover, could you please talk about how to terminate the thread before SubFunc() reaches its end in my example. I refer to some articles. They suggested to use CEvent and WaitForSingleObject(), as well as AfxEndThread().
I do not how to combine them to terminates a thread from another thread (main thread, in my case).
Thank you for your valuable time

Is it possible to reallocate using operator new?
// C
some_ptr = malloc( sizeof( some_type ) * n );
... // change "n"
some_ptr = realloc( sizeof( some_type ) * n );
// C++
some_ptr = new some_type[n];
... // change "n"
// Now what?
Best regards

The short answer is no. Either use a combination of malloc and realloc as in your example, or use the keyword new and copy the contents over to a larger buffer.
|
|

|

Use an STL collection such as vector, and you won't have to worry about the memory allocation.

is it possible to get file size if it is opened with fopen_s function? 
|
|
|
|
|
You may use fseek() to go the end of the file, and use ftell() to get file current position, which is now also the file size.
|
|
|
|
|
Once you have opened your file:
long size;
fseek(file,0,SEEK_END);
size = ftell(file);
rewind(file);

Hi,
In my application I created a wmv movie form 3 images. It also have the audio for 15 seconds. Audio per frame is variable means that we can have audiofor first frame for 2 sec , for second frame 10 sec and for 3rd frame 3 sec.
How can I achive this?
one solution can be variable frame rate for each frame. CAn we do this in wmv ? How can we do this? Is there any other alternative available to achive this
All help and guidelines are welcome
Thanks in advance
Regards,
Hemant.

Can't you keep a constant frame rate?
In your case one frame-per-second would work. So when you write the video stream you'd write
2 frames of the first image, 10 frames of the second image, and 3 of the third image.
Are you using a Video Image stream or a regular video stream for your wmv file?
|
|
|
|
|
What is difference between "Video Image stream" and "regular video stream"?
|
|
|
|
|
A video image stream is made up of still images. The stream is written differently than
regular "live" video when using the windows media sdk to write wmv files.
