I am working on an MFC project. I added some COM capabilities, built the Debug version. All worked well. When i tryed to switch to the Release build i got this error(first from list ... there were several others derived from it)
error C2065: '_AtlModule' : undeclared identifier
I think is a configuration derived error, but I'm not sure. Does anyone has any ideea about how to solve it ?

Hi all,

I have implemented Context Menu Extension on my namespace icon by implementing IContextMenu inteface. I have added 5 custom menus. This works fine for Win2k but I only see the first of this menus if I test it on Win XP. Can anyone tell me what is going wrong here?

Thanks and Regards,
Anil

What I am doing is fairly straightforward.. inside the QueryContextMenu function of my implementation of IContextMenu interface I am passed the menu handle of the context menu thats displayed....I am calling InsertMenuItem with the passed menu handle and each of my menu Items....

I was wondering if there is a registry entry or something of that sort that has to be changed so that we get to see all the menus...

The area that is shared between two or more processes is called Shared Memory.This helps in the interprocess communication where you want to allow changes made in all the instances of a single application .

Somethings seem HARD to do, until we know how to do them.

Normally each process has its own memory and data in processes A's memory can't be accessed in the memory of process B and vice versa. Shared memory is when the same physical memory is mapped into multiple processes. In our example this means that process A and B share some memory and thus the data in it is shared. Normally only a small amount of memory will be shared.

Hi Prashanth V,

Hw are u ??

Shared Memory is an efficeint means of passing data between programs. One program will create a memory portion which other processes (if permitted) can access.

There used to be a C function that any programmer could use for allocating memory off the stack. The memory was automatically deallocated when the calling function returned. This was a dangerous function to call. it’s not available anymore.

What is he possibly talking about?? Unsure | :~

AnyIdea?

Is the coding in C itself or you can use C++ Classes there, if yes the try Auto_ptr Smile | :)

The memory is deallocated automatically when program terminates

In case of java there is special garbage collecter for deallocation of the memory during run time

So its better that when you allocates memory inside the function then before returning allocated memory must deallocate. Smile | :)
