Description

With AsyncCalls you can execute multiple functions at the same time and synchronize them at every point in the function or method that started them. This allows you to execute time consuming code who's result is needed at a later time in a different thread. While the asynchronous function is executed the caller function can do other tasks.

The AsyncCalls unit offers a variety of function prototypes to call asynchronous functions. There are functions that can call asynchrony functions with one single parameter of the type: TObject, Integer, AnsiString, WideString, IInterface, Extended and Variant. Another function allows you to transfer a user defined value type (record) to the asynchrony function where it can be modify. And there are functions that can call asynchrony functions with a variable number of arguments. The arguments are specified in an const array of const and are automatically mapped to normal function arguments.

Demo Codes

This code, sleeps for 5 seconds, and shows message box.

Run(TAsyncTask,
  // Execute
  procedure (ATask: IAsyncTask)
  begin
    Sleep(5*1000);
  end,
  // Finish
  procedure (ATask: IAsyncTask)
  begin
      ShowMessage('Finished');
  end
);

This code downloads google's logo png file, and displays in TImage component

AniIndicator1.Visible := True;
Run(THttpAsyncTaskBitmap.Create('http://www.google.com/images/nav_logo129.png'),
  // Finish

Description

The components allow you to write multithreaded applications within a minutes. All the synchronization and the basic critical sections are implemented. Less time consuming progress and information browse mechanism. You can group the threads within a groups, start stop them, update the information for the thread with the highest update priority within the group and so on. Very flexible and easy to use.

Now having it's own synchro methods management component editor. Create, rename, go to the implementation, and generate synchro function calls with single click.

Description

EZThread component is an enhancement TThread class. It has been designed to provide extremely easy but efficient implementation and can be used whenever your codes need to be run in a thread. All properties and events can be directly specified in the Object Inspector.

The advantage of running your codes in a thread are many. For example, you can run a procedure in the background and still let the user operate your program or do other interface. Any procedure that takes considerable CPU time to complete is worthwhile for you to consider to run that procedure in a thread. These may include copying a large amount of files, scanning or searching a disk drive, sorting big arrays, checking and sending emails or other internet operations and many others.

Using EZThread is a breeze. Drop the component in your form and enter your codes(procedures) in the OnExecute event handler. Then, to start the thread running, call the Execute method. To terminate the thread, call Terminate. If you want to suspend the thread without terminating it, you can use Suspend and then Resume to resume the suspended thread.

Description

The TThread.Synchronize causes a method to be executed using the main thread, thereby avoiding multi-thread conflicts (expecially on the VCL). Unfortunately it only supports parameterless methods. This unit provides techniques to extend this to methods with parameters.

• Any method of a thread derived from TParamThread can be synchronized to the main thread using ParamSynchronize.
• Any method executed inside any thread can be synchronized to the main thread using the Execute method of TParamSynchronize. It can be accessed directly (it is a class method) or creating a TParamSynchronize object (a singleton).
• With some limitation about parameter types a thread derived from TParamThread can launch one of its method using ParamAsynchronize and go on without waiting for its completion.
• With some limitation about parameter types a any thread can launch any method using the Execute method of TParamAsynchronize and go on without waiting for its completion.

In the last two cases the method execution is delegated to a server thread and the execution can be synchronized or not to the main thread.

Description

Do you need to write a multithreaded applications? Are you annoyed of writing lines and lines of code for threads synchronization and CriticalSections for data protection? Would you believe that the thread is just a click away? Well here it is, the TBMThread is a native VCL component implementing everything you do need to create the thread and the synchronization, just dropping the component on the form. Sounds great, right? And it’s not all. Here is the Thread group now. Just set couple of threads to point to one and the same group and you can control and monitor all of them.

Description

This component creates thread and uses it to call its 'OnThreadChange' Event whenever the 'Change' method is invoked.

It's very useful for components, like TEdit and TComboBox, where a database lookup or other slow process will slow down the user interface.
