I was wondering why I didn't notice this type of memory leak reports already. I'm mostly very careful about it. I used vld dll for a while.
So it is possible that this does not result in a memory leak in VC++, but worse than that, it might lead to an unknown behavior. Why VC++ compiler doesn't generate a warning? or perhaps it does in level4?(I often use the default level3)

No, my understanding is that with VC++ it works fine either way (haven't tried it though  ). However, the C++ Standard says that such a case leads to undefined behavior which means that with other compilers (or a new version of VC++) you may see just about anything at all: leaks, crashes, destructors not being called - you name it.

Wow - four letter words get automagically beeped here.
I did write a 'i' instead of a '*" in the post above.

you must call delete [] if you have an array of objects.
if you leave out the [] the destructor only is called for the first object of the list.
So, to be sure not to get resource/memory leak you have to use [] for arrays.

I have written an application that has a system tray icon. When the OnClose() event of the main form is executed I just hide the form without letting the application exit. But my problem is when Windows is restarted the application cannot exit because the OS just sends WM_QUIT which does not terminate the program. Do you have any idea how I can solve this problem?
Thank you in advance!

Why not?

It's because when the main form receives WM_CLOSE I just hide it.

they are not the same thing. You said the app doesn't quit when WM_QUIT is sent. I asked why not and you answer with what you do in WM_CLOSE. Do you see a problem with this conversation?

Yes, you are right. I may not be doing the right thing
Thanks

(That question must have been answered before, but I'm not certain what to google for, and it's not urgent.)
I have a pop-up menu on a CTreeCtrl filled with dynamic values :
while( SomethingIsTrue)
{
groupMenu.AppendMenu(MF_STRING, 0, someDynamicString );
}
I know I could use a range of predefined range of values, but It will make thing harder since I will need to create a temporary map of value-pair between the menu ID and the string (data) that is inserted in the menu.
The pop-up is called with TrackPopupMenu, even if I use the TPM_RETURNCMD flag, I still need to have a valid ID to know which menu item was selected ?
The question I have is :
Is it possible to get the string from the selected menu item ?
Thanks.
Max.

I have an application MyApp which spawns 2 process A and B. MyApp cannot communicate to either A or B. MyApp first starts the process A and It has to wait untill A has completed initilization and reaches a stable state which is approx 4 mins. MyApp should remain idle during this time period. After 4 min, MyApp starts process B and should wait for approx 2 min and shutdown.
What is the best method for suspending MyApp for the above said duration using very little system resources? I do not want to use Sleep() for this purpose.

I am unsure if this applys to you, but have you considered WaitForSingleObject()?

Use the Event?!
WaitForSingleObject(..., 4 minutes, ...).

Why not it suspends the thread using very little system resources and so meets your requirements?

Perhaps he's afraid that he'll forget to set the alarm and oversleep.

If your app has a UI, and it stays visible during the waiting period,
then you could disable the main window for the duration. Set a one-shot
timer to wake it.
If there's no UI or you hide the app's UI while it's waiting then there's no
reason to Sleep() - it won't be doing anything. You still need a way to wake it though.

Hello,
is there a simple way to provide another process two simple int values?
Because a pipe between those 2 processes is a little bit to much work...
Is there a special area to create some variables in a "free access zone" ?
Big thanks

CreateFileMapping() & MapViewOfFile() would be reasonably "simple".

For two ints? 
I'd just use WM_COPYDATA[^]

I thought about that one, but its inherent insecurity made me think otherwise before recommending it.

2 ints fit in a regular window message.
