AppControl (Function) In french: AppliContrôle
 Warning
From version 23, AppliControl is kept for backward compatibility. This function has been replaced with AppControl.
This is an advanced function. The management of the remote check for a WINDEV application is automatically implemented when installing an application in network. This function must be used to customize the management mode of the remote check. Enables (or disables) the remote control for the current multi-user WINDEV application. The remote control allows you to "softly" disconnect the users from the WINDEV application in order to update the application (database update for example). The remote control is used to: - prevent from connecting to an application,
- notify the user that the application will be closed for updating,
- disconnect a user in order to update the application.
