Hi Matt, Yeah, Interested in the Socket Logger... Would be interested in having a look at the code.

Actually I have developed a threadsafe socket logger. Its pretty cool actually. You have an logger application running in your system tray and all you need to do is link in the client / helper units to your code and call LogMessage(text) Or LogMessage(Category, Text) the category will output onto a separate tab within the socket logger. I couldn't do without this tool for Delphi developing. It saves stuffing around with controls or text files, and is fully thread safe. I've used it on a number of commercial contracts and its been adopted as a usuful in house tool. If anyone is interested, I can forward through the code. Cheers, Matt. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Conor Boyd Sent: Thursday, 17 May 2007 9:54 a.m. To: NZ Borland Developers Group - Delphi List Subject: RE: [DUG] Best way to make this thread safe Yup, that should do the trick in this case. The following isn't really answering your question, and obviously it depends on the circumstances, but for logging for a developer's benefit, I just use the OutputDebugString function in the Windows unit, and then use DbgView from SysInternals to log the output from my apps that way. Don't have to worry about threading/logging issues then. Maybe that's some help to somebody. Cheers, C. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Alister Christie If you're wanting to manipulate the VCL you need to call synchronize(aMethod), which will sync your thread to the main application thread - the VCL is not thread-safe. In aMethod you could do your writelog. But I'm also not much of a threading expert so someone else may have a better method.
