Dear Friends:

I am using MapXtreme 2008 With C# I have very basic problem I need to create text on a specific X,Y. I am reading and trying but not able to do it.
I am able to insert images on a specific X,Y but not text I am really embraced with this problem. can anyone help me.
please help me.


Nabeel Ahmad.

please see the code

private void MapInfo_Geometry_LegacyText(double X1,double Y1, string MyText)
        Feature ftr;
        // Create a CoordSys for the Geometry to use.
        MapInfo.Geometry.CoordSysFactory factory = Session.Current.CoordSysFactory;
        MapInfo.Geometry.CoordSys csysWGS84 = factory.CreateCoordSys("EPSG:4326");
        double X2 = X1 + 0.01555;
        double Y2 = Y1 - 0.00173;
        DPoint pt = new MapInfo.Geometry.DPoint(X1, Y1);
        // Create LegacyText            
        MapInfo.Geometry.DRect rect = new MapInfo.Geometry.DRect(X1, Y1, X2, Y2);
        MapInfo.Geometry.LegacyText ltxt = new MapInfo.Geometry.LegacyText(csysWGS84, rect, MyText);
        double X = double.Parse(label_X.Text);
        double Y = double.Parse(label_Y.Text);
        TextFactory.CreateLegacyText(mapControl_Fs.Map.GetDisplayCoordSys(), pt, Alignment.TopCenter, label_INCIDENT_ID_1.Text, mapControl_Fs.Map, new MapInfo.Styles.Font("Microsoft Sans Serif", 20));
        MapInfo.Geometry.FeatureGeometry g = new MapInfo.Geometry.Ellipse(csysWGS84, pt, 0.003, 0.003, DistanceUnit.Kilometer, DistanceType.Spherical);
        MapInfo.Styles.SimpleInterior sis = new MapInfo.Styles.SimpleInterior(2, Color.Red);
        MapInfo.Styles.LineWidth lw = new MapInfo.Styles.LineWidth(1, MapInfo.Styles.LineWidthUnit.Point);
        MapInfo.Styles.SimpleLineStyle sl = new MapInfo.Styles.SimpleLineStyle(lw, 3, Color.Empty);
        MapInfo.Styles.AreaStyle ar = new MapInfo.Styles.AreaStyle(sl, sis);
        MapInfo.Styles.CompositeStyle cs = new MapInfo.Styles.CompositeStyle(ar, null, null, null);
        MapInfo.Mapping.FeatureOverrideStyleModifier fsm = new MapInfo.Mapping.FeatureOverrideStyleModifier("a", cs);
        MapInfo.Data.MIConnection conn = new MapInfo.Data.MIConnection();
        MapInfo.Data.Table tbl;
        //Here I need to Make sure that the temporary table does not exist before creating.

        tbl = conn.Catalog.GetTable("tbl_PointAdd");
        if (tbl != null)
        MapInfo.Data.TableInfoMemTable ti = new MapInfo.Data.TableInfoMemTable("tbl_PointAdd");
        ti.Temporary = true;
        tbl = conn.Catalog.CreateTable(ti);
        MapInfo.Mapping.FeatureLayer lyr = new MapInfo.Mapping.FeatureLayer(tbl, "tbl_PointAnimation");
        MapInfo.Data.MICommand cmd = conn.CreateCommand();
        ftr = new MapInfo.Data.Feature(g, cs);
        lyr.VolatilityHint = MapInfo.Mapping.LayerVolatilityHint.Animate;
    catch (Exception ex)

Mr. Richard: Actually I do not know that I am using right method to insert the text on a specific XY, if you know can you please send me a piece of code to insert text on the map at specific coordinate. Thank you, Regards: Nabeel Ahmad

Sorry, but I have no knowledge of MapXtreme so I could not comment.

Sometime, taking some time to actually read the documentation helps!

Check this out: MapXtreme Developer's Guide. See page 253 and onwards

Venerable Ryan Zahra: sure I have read many time as well as I have also getting knowledge from this website
but I am not succeeded. I do not know where I am wrong. anyhow if someone has the answer or piece of code for some lines I will appreciate it.
Thank You,
