IMapTopobase.SaveToFile

Syntax

SaveToFile(FileName: String);

Parameters

FileName. Name of the file, to which a topobase will be saved.

Description

The SaveToFile method saves a topobase to a file.

Example

Executing the example requires a form with the following components: the Button component named Button1, the MapBox component named MapBox1, and the UiMap component named UiMap1. UiMap1 is a data source for MapBox1. The file system should include the C:\MAP_RF.tbs file containing a topobase.

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

Add links to the ExtCtrls, Forms, Map, Metabase, and Ui system assemblies.

Sub Button1OnClick(Sender: Object; Args: IMouseEventArgs);
Var
    MetaBase: IMetabase;
    TopoBase: IMapTopobase;
    Map: IMap;
Begin
    MetaBase := MetabaseClass.Active;
    TopoBase := MetaBase.ItemById("MAP_RF").Bind As IMapTopobase;
    Map := UiMap1.Map;
    Map.Topobase := TopoBase;
    TopoBase.SaveToFile("C:\MAP_RF.tbs");
    WinApplication.InformationBox("Topobase '" + TopoBase.Name + "' is saved to file");
End Sub Button1OnClick;

After executing the example the MAP_RF map is loaded to the MapBox component. Then the topobase is saved to the C:\MAP_RF.tbs file, and an appropriate information message is displayed.
