IMetabaseUpdate.LoadFromFileNF

Fore Syntax

LoadFromFileNF(FileName: String; [Mode: UpdateLoadMode = 0]);

Fore.NET Syntax

LoadFromFileNF(FileName: System.String; Prognoz.Platform.Interop.Metabase.UpdateLoadMode);

Parameters

FileName. Full name of the update file.

Mode. Method of loading objects into the update. Optional parameter.

Description

The LoadFromFileNF method loads an update from a file with the *.pef extension.

Comments

The *.pefx format enables to save bigger number of objects to the update, comparing with the *.pef format. Use the IMetabaseUpdate.LoadFromFile method to load an update from the old *.pef format.

Fore Example

To execute the example, add a link to the Metabase system assembly. The C:\Update_1.pefx update file is required.

Sub UserProc;
Var
    MB: IMetabase;
    Update: IMetabaseUpdate;
    SpecialObjNode: IMetabaseUpdateSpecialObjectsNode;
Begin
    MB := MetabaseClass.Active;
    Update := Mb.CreateUpdate;
    Update.LoadFromFileNF("C:\Update_1.pefx");
    SpecialObjNode := Update.SpecialObjectsNode;
    SpecialObjNode.ApplyObject(MetabaseSpecialObject.SharedParams) := True;
    Update.SaveToFileNF("C:\Update_2.pefx");
End Sub UserProc;

After executing the example a special object - global variables - is added to the update, loaded from the C:\Update_1.pefx file. Then the update is saved in other file.

Fore.NET Example

The C:\Update_1.pefx update file is required. The specified procedure is an entry point for the .NET assembly.

Public Shared Sub Main(Params: StartParams);
Var
    MB: IMetabase;
    Update: IMetabaseUpdate;
    SpecialObjNode: IMetabaseUpdateSpecialObjectsNode;
Begin
    MB := Params.Metabase;
    Update := Mb.CreateUpdate();
    Update.LoadFromFileNF("C:\"+ "Update_1.pefx", UpdateLoadMode.ulmReplace);
    SpecialObjNode := Update.SpecialObjectsNode;
    SpecialObjNode.ApplyObject[MetabaseSpecialObject.msoSharedParams] := True;
    Update.SaveToFileNF("C:\" + "Update_2.pefx");
End Sub;

After executing the example a special object - global variables - is added to the update, loaded from the C:\Update_1.pefx file. Then the update is saved in other file.
