Therefore, only one thread at a time can manipulate the value of the variables.Д¬ritical Sections are not depending on their position in the code. Only one thread at a time can be within the critical section. Windows offers CriticalSections as a mean of thread control. Once you decide to access a global variable, work with it, change its value and write it back you have to ensure that no other thread will do the same with this variable at the same time. The problem mentioned before is the 'critical section' of your thread. However, in threaded applications you will often have to use them in order to exchange processing informations. NOTE: For all of you how 'hate' global variables, I do too. However, reading a variable, working with it and writing the new value back to the variable, will certainly bring you in trouble if two threads do this at the same time. Reading global variables out of a thread will, usually, not create problems. In multi-threaded applications you do not have this kind of control anymore, because multiple threads can access the variable at the same time. Using Threads can open little 'trouble cans.' In single-threaded apps you have control over the execution order of your tasks and the way they access global variables. You want to learn working with Threads :) The accomplished tasks run idle some of their working time Your application runs on multi-processor systems Multiple, independent tasks need to be accomplished However, on a multi-processor machine you will, almost certainly, gain speed using threading. If some task(s) have to be accomplished before the application can continue and all of these tasks are rather demanding for the processor you may consider not to use threading. your normal Delphi app) will have to wait until every task is accomplished before running the next one - mutli-threaded apps work them parallel.Д®ither you want to support multi-processor machines or you know your tasks depend on other tasks and not only on your calculations.Д®specially on single processor machines the use of threads may actually degrade the performance of your whole application. This will come in handy in different cases like multiple-processor machines or if one task has to wait for something else (e.q. Within you applications you can make use of these feature by using threads.

Operationg systems like Windows NT or Windows 2000, however, support multi-tasking, allowing multiple processes to work at virtualyl the same time. Usually your Delphi applications will accomplish one task after another. This allows you to process different tasks parallel. Threads will allow you to open up one or more additional processes within your application.

In another article I will show you how to work around this problem, however, until then you may search the web for workarounds. This unit, however, is a Delphi Enterprise feature. You need the unit SyncObjs (part of Delphi Enterprise) for this sample.ДЄs mentioned in the Abstract, you will need the unit SyncObjs. This article will show you how to create Threads and show you how to work with global variables within a Thread.
