    <Parameter value>: Character string or integer
    Value to save.
    Remarks

    Name of the parameter in a registry

    • Case 1: the name of the parameter is "Param1":
      This parameter is saved in the registry by using the following path:
      HKEY_CURRENT_USER\Software\<Company>\<Application>\Param1
    • Case 2: the name of the parameter is "WIN_Window1\EDT_Edit2\Param1":
      This parameter is saved in the registry by using the following path:
      HKEY_CURRENT_USER\Software\<Company>\<Application>\WIN_Window1\EDT_Edit2\Param1
    • Case 3: the name of the parameter is "WIN_Window1.EDT_Edit2.Param1":
      This parameter is saved in the registry by using the following path:
      HKEY_CURRENT_USER\Software\<Company>\<Application>\WIN_Window1\EDT_Edit2\Param1
    Reminder: To find out the path of the registry where the application information is stored, use ProjectInfo associated with the piRegistry constant.
    <Company> corresponds to the company specified when creating the executable. If this name is not specified, <Company> corresponds to "WINDEV applications".
    Note: In Test mode, the path used in the registry is as follows: HKEY_CURRENT_USER\SOFTWARE\PC SOFT\WinDev\24.0\TestMode\<project>.

    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.
