Hi,

I need to find the bottlenecks in my program so I can re-write them.  Anybody got any suggestions how to find them?

Are there any programs you could suggest that could profile the way my program runs?  And which functions get most of the clock cycles?

Is there a built in tool in VS2003?

Also, what about calling Destroy()?

When I came from C++ I was told you don't need to clean up after yourself, the environment does that for you.  But lately I've hear dthat's not true.  Meanwhile I have done nothing to override Destroy() and remove my objects.

What re some basic rules I can use to start going through my numerous objects and dialogs to start implementing Destroy()?

When a dialog cals its destroy, should I be destroying the controls I created in that dialog?  What function do I call?  Do I set it to null as well?

Thanks for any help you provide.  I'm in a pickle and can't get out of it.

Bob

You'll save yourself much time by not guessing.  Get a profiler like red-gate.com ants profiler and it will show you exactly where your program spends its time.

In C# you do not destruct objects.  The garbage collector does that for you.   (You mentioned hearing that this is not true - can you provide more information about this?)  There is a standard pattern in C# that says if you design an object that contains unmanaged resources then implement IDisposable.  Consumers of a class that implements IDisposable should call its Dispose method when finished with it.   The reason is the CLR garbage collector only works with managed objects.  So if your application creates a COM object or uses a C++ DLL you still need to handle destruction of resources those may utilize.

I agree with mastoo, Ants is worth a look.  If i recall, they have a free trial version too.  Alternatively you can instrument your code with Log4Net (open source).

Well I have heard caims that I still need to destroy objects in certain case, using C#.  Not long ago I made a dialog with a timer.  And when the timer fired, a function executed.  but when I closed th edialog, it still executed.  That's one example of when I needed to explicity set it to null in the destroy function of the dialog.
