Example

// Returns the point in the map corresponding to the current user position
MyPosition is geoPosition
MyPosition..Latitude = 1.442951
MyPosition..Longitude = 43.604363
Trace(MapInfoPosition(MAP_Position, MyPosition))

// Returns the point in the map corresponding to the current user position
MyPosition is geoPosition
MyPosition = GPSGetPosition()
IF ErrorOccurred = False THEN
RESULT MapInfoPosition(MAP_Position, MyPosition)
END

Syntax

<Result> = MapInfoPosition(<Map control> , <Position>)

<Result>: Character string

Coordinates of the point corresponding to the geographical position. The coordinates are returned in the following format:

<X> + TAB + <Y>

<Map control>: Control name

Name of Map control to use. If this parameter corresponds to an empty string (""), the Map control to which the current event belongs will be used.

<Position>: geoPosition variable

Name of the geoPosition variable corresponding to the geographical position whose coordinates are sought on the map.

Remarks

The coordinates returned by MapInfoPosition can correspond to a point that is not currently visible in the Map control (negative coordinates for example).
The calculation of position takes into account the zoom level in the Map control during the call to the function. The higher the zoom level is, the more precise the coordinates will be.
