Example

Executing the example requires a form with the following components: the Button component named Button1, the TabSheetBox component named TabSheetBox1, and the UiErAnalyzer component named UiErAnalyzer1. UiErAnalyzer1 is a data source for TabSheetBox1. A working area of the time series database should be loaded to UiErAnalyzer1.

The example is a handler of the OnClick event for the Button1 component.

Add links to the Express, ExtCtrls, Forms, Laner, and Tab system assemblies.

Sub Button1OnClick(Sender: Object; Args: IMouseEventArgs);
Var
    pContext: ILanerContext;
    Laner: ILaner;
Begin
    pContext := New LanerContext.Create;
    Laner := UiErAnalyzer1.ErAnalyzer.Laner;
    If Not pContext.IsRegistered(Laner) Then
        pContext.Register(Laner);
    End If;
End Sub Button1OnClick;

After executing the example the working area of the time series database is registered in context of the time series database, if it has not yet been registered there.
