[DUG] Sending data between process on same computer on windows

[Jason Coley]

Do you have any samples on how to work this component, I can't find much
on the net about it either, apart from download links.

	I would use shared memory.  I use this free component.

	
http://www.torry.net/vcl/system/appscommunications/sharedmemory.zip

	 

	It uses a memory mapped file system but without a physical file.
It can use messages for triggering events at each end, but I actually
use a variable in a record which I check in a 10ms loop to know when to
do something.  It works very well.

	Shared memory of course!

	 

	How much data are you talking about, how often?

	 

	For IPC, IMO, I would never use Sendmessage for something that
needed to be 100% reliable.

	Hello everyone,

	 

	May I ask what is the fastest way to send data between process
on same computer on windows? I assume sendmessage api faster than
semaphore waiting, of course faster than TCP/IP which will go through
huge amounts of tcp/ip stack. I just want lowest overhead on per call.
Anyone have any experiences on that?

	 

	TIA

	 

	Regards

	Leigh
