// Delete a marker
MyMarker is Marker
MyMarker..Name = "Destination"
MyMarker..Position..Latitude = 43.613708
MyMarker..Position..Longitude = 3.876972

IF CBOX_DisplayMyDestination = True THEN
MapAddMarker(MAP_Position, MyMarker)
ELSE
MapDeleteMarker(MAP_Position, MyMarker)
END
Syntax
<Result> = MapDeleteMarker([<Map Control> [, <Marker>]])
<Result>: Boolean
  • True if the marker was deleted,
  • False otherwise. To find out the error details, use ErrorInfo.
<Map Control>: Optional control name
Name of Map control to use. If this parameter is not specified or if it corresponds to an empty string (""), the Map control to which the current process belongs will be used.
<Marker>: Marker variable or optional character string
Marker to delete. This parameter can correspond to:
  • a Marker variable corresponding to the marker to delete.
  • a character string corresponding to the name of the marker to delete. This name corresponds to the ..Name property of the Marker variable.
If this parameter is not specified, all the markers will be deleted from the map (equivalent to MapDeleteAll).
Remarks
  • Only a marker previously added to the Map control can be deleted.
  • To add a new marker into a Map control, use MapAddMarker.
  • To modify a marker displayed in a Map control, use MapModifyMarker.
