WD Persistence Training (WINDEV): WD Persistence
[ + ] This example presents the use of InitParameter, LoadParameter and SaveParameter.
These functions are used to configure the backup of controls, variables and other parameters.
This example is divided into three parts:
- The configuration
- The manual management of variables (SaveParameter and LoadParameter)
- The optimization
1°) Configuration

The configuration window enables you to modify the location of the backup of parameters (registry, INI file, XML file) as well as its path (registry key or file path).
2°) Manual management of the variables
The manual management enables you to save the content of the variables via SaveParameter and to restore them via LoadParameter. Each parameter is identified by a name. These values are saved at the location defined in the configuration window.
3°) The optimization
This window explains how to optimize your code to avoid the slowness caused when the saved values are restored. Indeed, when restoring the value of a control, its modification code is run. If you have long processes (queries with parameters for instance), this window shows you how to speed up the loading of the window.
The AssistedInput functions Unit examples (WINDEV): The AssistedInput functions
[ + ] Using the WLanguage AssistedInput functions.
These functions are used to easily implement an assisted input on the controls.
