If your thread must wait for another thread to finish some task, you can tell your thread to temporarily suspend execution. You can either Wait for another thread to completely finish executing, or Wait for a task to be completed.

To wait for another thread to finish executing, use the WaitFor method of that other thread. WaitFor doesn't return until the other thread terminates, either by finishing its own...

To avoid clashing with other threads when accessing global objects or variables, you may need to block the execution of other threads until your thread code has finished an operation. Be careful not to block other execution threads unnecessarily. Doing so can cause performance to degrade seriously and negate most of the advantages of using multiple threads.

The VCL and CLX include support for three techniques that prevent other threads from...

How to use the main VCL/CLX thread?

The Execute method is your thread function. You can think of it as a program that is launched by your application, except that it shares the same process space. Writing the thread function is a little trickier than writing a separate program because you must make sure that you don't overwrite memory that is used by other threads in your application. On the other hand, because the thread shares the same process space with other threads, you can use the...

C++Builder provides several objects that make writing multi-threaded applications easier. Multi-threaded applications are applications that include several simultaneous paths of execution. While using multiple threads requires careful thought, it can enhance your programs by: Avoiding bottlenecks. With only one thread, a program must stop all execution when waiting for slow processes such as accessing files on disk...
