InitParameter (Function)

In french: InitParamètre

Initializes the management of persistent values. Specifies the location used to store:

the values of the persistent controls.
the size and position of the controls and windows.
the values managed by SaveParameter and LoadParameter.

Note The initialization of persistent values is "global". Therefore, if a component initializes the management of persistent values, the management of persistent values will be initialized for the application that uses the component.

Example

// Parameters of persistent values 
// in a .XML file that depends on the user 
InitParameter(paramXML, "Param_" + USER + ".xml")

// Parameters of persistent values
// Parameters via a string
MyString is string
MyString = fLoadText("MyFile.xml")
InitParameter(paramString, MyString)

Syntax

<Result> = InitParameter(<Initialization mode> [, <Source of values>])

<Result>: Character string

Initialization mode used before the call to InitParameter. <Result> has the following format:
<Initialization Mode> + TAB + <Source of Values>

<Initialization mode>: Integer constant

Type of backup for the persistent data:
paramIni The parameters will be saved in a [Global] section of a file in .INI format.
If this option is selected:
the INI file is named <Project name>.INI by default. This file is created in the directory of the executable.
This file is created in the "/Library" directory of the application.
<Source of values> corresponds to the name of the .INI file to be used.
If this directory is not specified, the file is created in the executable directory.
If this directory is not specified, the file is created in the "/Library" directory of the application.
paramRegistry The parameters will be saved in the registry.
If this option is selected:
by default, the entry used corresponds to the result of ProjectInfo(piRegistry) (which means HKEY_CURRENT_USER\Software\<Company>\<Project name>)
<Company> corresponds to the company specified when creating the executable. If this name is not specified, <Company> corresponds to "WINDEV applications".
in Test mode, the path used in the registry is as follows: HKEY_CURRENT_USER\SOFTWARE\PC SOFT\WinDev\30\ModeTest\<Nom du projet>.
<Source of values> corresponds to the registry entry to be used.
<Source of values> will be ignored. If this mode is chosen to store persistent data, the data is stored in the system preferences.
paramString The parameters will be read in an XML string. <Source of values> (mandatory parameter) must be a string variable.
In this case, the parameters are not saved in an XML file but in the string variable.
This constant can be used to retrieve parameters coming from an HTTP server (parameters returned by HTTPRequest for example).
paramXML The parameters will be saved in a file in .XML format.
If this option is selected:
the XML file is named <Project name>.XML by default. This file is created in the directory of the executable.
This file is created in the "/Library" directory of the application.
<Source of values> corresponds to the name of the .XML file to be used.
If this directory is not specified, the file is created in the executable directory.
If this directory is not specified, the file is created in the "/Library" directory of the application.

<Source of values>: Optional character string

This parameter depends on the selected initialization mode.
