Where i can find a good guide or tutorial to debug multithread delphi applications?

i'am looking for tips ,a guide开发者_运维知识库 or tutorial to debug multithread delphi applications.

where can find such info?

thanks in advance.

At this year's CodeRage, Boian Mitov of Mitov Software gave an excellent lecture on multi-threading in Delphi. It includes tips and tricks and things to watch out for. Although this isn't directly a "how to debug" tutorial, it discusses common problems, and approaches he recommends and why.

http://www.embarcadero.com/coderage5/sessions: Technical Session #44, on Thursday. (Best to download the MP4 and play it full screen so you can read all the text in the IDE. His accent is a bit strong, but he's totally understandable. )

(I use Mitov's real-time video library (VideoLab for Delphi and .NET) and his plotting and signal labs in a commercial product. They make heavy use of threads, are extremely fast and very reliable. This guy knows what he's doing, IMO.)

If your application is not yet written, consider using a framework dedicated to multi-threading.

Take a look at http://otl.17slon.com

Using such high-level units will make your debugging much easier, because it provides you with a lot of dedicated classes and methods, which will handle most of the multi-thread problems for you.

Sometimes, refactoring could be much more productive than debugging a badly designed application.
