Hello Scott.

i have made a com to be communicated between process.
but it is too slow
for example,
if i call a method of com from client.
like below
i made some function called a function of com
<Client Side>
iMyinterface->ComMethode();
iMyinterface->ComMethode();
iMyinterface->ComMethode();
iMyinterface->ComMethode();
iMyinterface->ComMethode();
Sleep(1);
it is too slow if i call a method of com many times like obove.

so i want to use a shared memory between process.

if i put all of data to shared memory, it is too much size to use the data.

so i just want to put a address of object into shared memory.

for example)

i put a adddress of instance to shared memory, if i need to use the object.

i will use cast with the address.

how do you think if i create a object with GlobalHeap like below?

void *MyClass::operator new(size_t size)
{
m_pMem = GlobalAllocPtr(GMEM_FIXED, (DWORD)size); // Use GlobalAlloc
return m_pMem;
}

help me...

hello everyone..

i want to get a address of from other process.

i wrote what i want to make a program.

i have two process to be commnunicated with each other.

so One process make a shared memory, some of object will be created in
this
process, then i will put the address of object to shared memory.

the other process will get the address of shared memory,
The shared memory have a address of object made by other process.

i have made this kind of idea, but the program have problem like "access
violation"

Actually, i want to use com but it is too slow between process.
can i make a shared dll ?
how can i solve this problem .
Do you have any idea to share a address of object.

It is useless to share an address between two processes. Each process has a
unique and private address space that cannot be accessed from other
processes. You can create shared memory, but not shared addresses.

You have proposed an invalid solution to your problem and asked how to
implement it. But what is the problem you are trying to solve?
