Good morning.
How do I know in VBA if the map that I loaded in my control map is WGS84?

Comparison of coordinate systems can be difficult since often there is no canonical definition. Therefore for practical purposes I would recommend GeoProjection.get_IsSameExt:
private bool IsWgs84(AxMap map)
    var gp = new GeoProjection();
    return map.GeoProjection.get_IsSameExt(gp, axMap1.Extents);
Hope it helps,

Ok. I solved in this way to get Datum:

MyImg.GeoProjection.NAME 'returns mapdatum eg WGS 84, ED50, etc

Thank you.

Fine, just be cautious, since the name may be different even if a definition is the same.
