If it's a large amount of data, a combination of SendMessage and Memory mapped files is very fast and efficient. ( SendMessage to notify and MMF to store the data )

I needed a way to send messages from a screensaver I was writing to another process on the same box, and SendMessage didn't seem to work when a screensaver was active (which I found strange, but anyway...), and the IPC stuff from madshi works flawlessly. HTH, C. ________________________________ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Leigh Wanstead 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?
