TThread and Database Reading
What I'm trying to do is to setup about 10 or 20 threads to handle reading and processing of a dataset. The situation is that I'm importing very large files so the extra time taken on the next command as it seeks and finds the record on the hard drive is an overhead so I was thinking that if I setup multi threading on it, then each thread could be handling it's own reading and processing at the same time so that it should be faster.

Creating a MP3 player
"Just for the records: to code a MP3 player with Delphi we have several possibilities. First: we could write a program that remotely controls another application like the WinAmp player.

Does anybody knows how can i execute a command file (it is a .bat file) that is placed to another PC (in a LAN)?
