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.

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.

• 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.

The major advantage of this component is that it requires NO extra DLLs.

The component has 2 events: OnSleep and OnAwake.

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