IMapTopobase.LoadFromFile

Syntax

LoadFromFile(FileName: String);

Parameters

FileName - name of the file, from which a topobase should be loaded.

Description

The LoadFromFile method loads a topobase from a file.

Example

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

Sub Button1OnClick(Sender: Object; Args: IMouseEventArgs);

Var

TopoBase: IMapTopobase;

Map: IMap;

Begin

TopoBase := New DxMapTopobase.Create As IMapTopobase;

TopoBase.LoadFromFile("C:\MAP_RF.tbs");

Map := UiMap1.Map;

Map.Topobase := TopoBase;

End Sub Button1OnClick;

After executing the example the topobase from the C:\MAP_RF.tbs file is loaded to the MapBox component.
