Using Synchronise

[nicasa]

Hi All

What is the correct way to call synchronise() in a thread ? I want to be able to call a function using a pointer to main form like this:

synchronise(pMyForm->MyFunction());

It does not work !! Does MyFunction() need to be a vcl function ??

HELP ....

I assume here a TThread.
Mark Cashman (

) I think describes it very well.

"Synchronize is a special function provided by TThread. It acts like a critical section for accessing forms controlled by the main thread (the thread which is represented by your Project Source.cpp file). You pass it a pointer to a function in your thread class and Synchronize executes it as if it were a function in the main thread. Only one thread at a time can execute in the main thread context, so Synchronize lets you serialize access to main thread resources like controls and tables - where parallel (and potentially interrupted) access by multiple threads could leave important data structures in an inconsistent (and thus crash-prone) state."

Hope this helps.
