Overview
WINDEV and WINDEV Mobile propose several functions used to perform an advanced management of threads.
Threads allow running code (or processes) in parallel with the main application. Therefore, several processes can be run in the background without locking the main application.
Threads replace some types of timers.
An efficient thread is a thread that waits for an event such as a user action, an incoming email, an incoming phone call, etc.
Examples for using threads:
  • Retrieving emails in the background while entering a new email, for example.
  • Communication application: managing phone calls, communication via sockets, etc.
From simple management to advanced management of threads
WINDEV proposes several features for managing threads:

[ + ] Using threads in an application:
- Run a procedure in thread format
- Stop a thread
- Run a procedure that expects parameters in thread format
The threads Unit examples (WINDEV Mobile): The threads
[ + ] Using threads in an application:
- run a procedure in thread format
- stop a thread
- run a procedure that expects parameters in thread format
The threads (pool) Unit examples (WINDEV): The threads (pool)
[ + ] Using threads:
- Running processes started in parallel
- Limiting the number of threads in execution at a given time
Reminder: A thread is a process running in parallel to the current application (main thread).
This allows you to run a task in background task for example (backup, ...).
Threads are very useful in the industry: supervisor, applications with real-time process check, and so on …
WD Using sockets Training (WINDEV): WD Using sockets
[ + ] This example presents the use of the "Socket" functions of WINDEV in Client/Server.
The following topics are presented in this example:
1/ How to connect to a socket
2/ How to accept a request for connection
3/ How to write or read on a socket
Summary of the example supplied with WINDEV:
This example presents the different functions for socket management supplied with WINDEV. To use this example, a first instance of the example must be started in "server" mode. Then, by specifying the name of the computer that will be used as server and a nickname, you can connect to this application in "client" mode. You now have the ability to send messages to all the connected users. In this example, a thread and a socket are associated with each connection.
