ILanerContext.CreateCopy

Fore Syntax

CreateCopy(Laner: ILaner): IMetabaseObjectDescriptor;

Fore.NET Syntax

CreateCopy(Laner: Prognoz.Platform.Interop.Laner.ILaner): Prognoz.Platform.Interop.Metabase.IMetabaseObjectDescriptor;

Parameters

Laner. A workbook.

Description

The CreateCopy method creates a copy of the specified workbook.

Comments

A workbook can be used only in one context. To register a workbook in several contexts, use its copies.

During copying of a workbook within one context all formulas that use series from other workbooks are saved. During copying of a workbook between different contexts the formulas that contain dependences on other workbooks are lost.

Fore Example

Executing this example requires a form containing:

A button with the Button1 identifier.
The LanerBox component.
The UiErAnalyzer component with the UiErAnalyzer1 identifier that is used as data source for LanerBox. Workbook of the time series database must be loaded to UiErAnalyzer1.

There should also be the pContext variable that contains context.

Add a link to the Metabase system assembly. Example is a handler of the OnClick event for the button.

Sub Button1OnClick(Sender: Object; Args: IMouseEventArgs);
Var
    pContext: ILanerContext;
    Laner: ILaner;
    LanerObject: IMetabaseObjectDescriptor;
Begin
    pContext.BeginLoad;
    Laner := UiErAnalyzer1.ErAnalyzer.Laner;
    If Not Laner.IsInContext Then
        pContext.Register(Laner);
    Else
        LanerObject := pContext.CreateCopy(Laner);
        pContext.Register((LanerObject As IEaxAnalyzer).Laner);
        pContext.EndLoad;
    End If;
End Sub Button1OnClick;

After executing the example, a workbook is registered in a context. If it is already in the context, then its copy is registered.

Fore.NET Example

Executing the example requires a .NET form containing:

A button with the button1 identifier.
The LanerBoxNet component.
The UiErAnalyzerNet component with the uiErAnalyzerNet1 identifier that is a data source for LanerBoxNet. Workbook of the time series database must be loaded to uiErAnalyzerNet1.

Example is a handler of the Click event for the button.

Imports Prognoz.Platform.Interop.Laner;
Imports Prognoz.Platform.Interop.Express;
…
Private Sub button1_Click(sender: System.Object; e: System.EventArgs);
Var
    pContext: ILanerContext;
    Laner: ILaner;
    LanerObject: IMetabaseObjectDescriptor;
Begin
    pContext.BeginLoad();
    Laner := uiErAnalyzerNet1.ErAnalyzer.ErAnalyzer.Laner;
    If Not Laner.IsInContext Then
        pContext.Register(Laner As LanerFactory);
    Else
        LanerObject := pContext.CreateCopy(Laner As LanerFactory);
        pContext.Register((LanerObject As IEaxAnalyzer).Laner);
        pContext.EndLoad();
    End If;
End Sub;

After executing the example, a workbook is registered in a context. If it is already in the context, then its copy is registered.
