Example

To execute an example create a form, put components on it: a button with the Button1 identifier and a multiline text editor with the Memo1 identifier. Add links to the Metabase, Dal, Db system assemblies. It is supposed that the repository contains a database with the DATA identifier.

The example is a handler of the OnClick event for a button.

    Sub Button1OnClick(Sender: Object; Args: IMouseEventArgs);
    Var
        MB: IMetabase;
        DB: IDatabaseInstance;
        SC: ISecurityConnection;
        S: ISecurityPackageLogonDataEx;
        Index: integer;
    Begin
        MB := MetabaseClass.Active;
        DB := MB.ItemById("DATA").Open(Null) As IDatabaseInstance;
        SC := DB.Connection;
        S := SC.LogonData As ISecurityPackageLogonDataEx;
        Index := S.ParamIndex("SCHEME");
        memo1.Lines.Add(S.ParamDescription(Index) + " " + S.IsLocal(Index).ToString);
    End Sub Button1OnClick;

On clicking the button a description of security module parameter and a possibility to use it as a shared variable are displayed into text editor.
