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...
Shared memory is very fast, so you probably want some way to manage the
shared data in shared memory. But you cannot use pointers in shared memory.
Perhaps what you need is multiple smaller shared memory segments. This
should require the same amount of storage that you use now to store the
data.
