The devil is in the detail in this kind of stuff, and your actual implementation can have a great effect.
As implied, the best method will be to develop 2 or 3 different methods, test and compare the results. Myles.

I was more interested in something that worked and was reliable. Cheers, Conor ________________________________ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Leigh Wanstead May I ask which is faster, ipc or sendmessage? -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Conor Boyd I found the IPC functionality from madshi.net (http://help.madshi.net/IPC.htm <http://help.madshi.net/IPC.htm> ) to work very nicely. 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. ________________________________ 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? Attention: This communication is confidential and may be legally privileged.
