I want to use the queryshape function on an existing shape of the map. The map will have several shapes and a dataset and plotted waypoints. I can find the waypoints, dataset, return records etc. But how do I go about finding the shape that the waypoint/records are located in. I have tried all kinds of stuff with no luck! Queryshape is based on locations so . . . can you return the shape that a given location ie x,y or long/lat resides in so as to use queryshape to return records in the next step or just how can it be done. ANYONE ? ? ?

Hi,

I'm not sure I understeand your question. QueryShape returns records that are _in_ the shape. Is that what you want ? If not, can you repeat your question in simple English? (I'm not English spoken) because now your question it is a little confusing..

I have an exisiting map with several ploygons around several dataset records in each ploygon. How can I access each ploygon(shape) and return the records that are in it.

The queryshape function will do it but it requires locations of shape edges/vertices? i think. I have tried programicly naming the shapes . . no luck. and several other things.

Hi,

This shows the pushpins in a shape:

Code:

    Loc = MP.ActiveMap.GetLocation(Lat, Lon, Alt);
    Shape s = MP.ActiveMap.Shapes.AddShape(GeoAutoShapeType.geoShapeRadius, Loc, 100, 100);
    s.Line.Weight = 0;
    s.Select();
    object o = 1;
    Recordset rs = MP.ActiveMap.DataSets.get_Item(ref o).QueryShape(s);
    rs.MoveFirst();
    while (!rs.EOF) {
        // here we have all pushpins
        rs.MoveNext();
    }

This move pushpins in a shape to a new dataset:

Code:

    MapPoint.DataSet InCircle = MP.ActiveMap.DataSets.AddPushpinSet("In circle");
    rs.MoveFirst();
    while (!rs.EOF) {
        rs.Pushpin.MoveTo(InCircle);
        rs.MoveNext();
    }
    o = "In circle";
    rs = MP.ActiveMap.DataSets.get_Item(ref o).QueryShape(s);
    rs.MoveFirst();
    while (!rs.EOF) {
        // here we have all pushpins
        rs.MoveNext();
    }

But the shapes are existing. I don't want to add shapes just return the existing shapes. Shapes will be created by user before accessing the map.

You should be able to iterate through the Shapes collection?
Wilfried adds a new shape to this collection so he knows which one he is working with.

Iterate through the shapes, testing each against the pin(s).

Ok,

I have a related problem. I have a series of concentric circles that radiate out from a point. I have a bunch of imported records. What I need to do is
to get the records in each zone. That is to say, the records that are in the first shape, the records that are in the second shape. The problem is that the records in the first shape are also in the second shape because the circles are concentric.

Basically I want to get records in zones radiating out from my centre location, that is to say those that are at least 10 miles out but no more than 20 miles out for example.

Regards,
Bob.

Hi Bob,

If you're using MapPoint 2010, you can manually do the following
(earlier version will require programming):


Select the most central, smallest circle and export the pushpins to Excel as Tab1, then delete the pushpins within that circle using the context menu.
Repeat this process in progressively larger circles til complete.

Thanks Mike,

I was afraid that was what you were going to say !! A more general question perhaps?

Why is it that the Mappoint object model is so restrictive. I cant manipulate or filter recordsets, I cant add fields to pushpins, I cant move pushpins that have been imported from Exel to other collections. It seems as if Microsoft have come up with a great product and then gone out of their way to cripple it.



I can't help feeling that there must be an underlying reason why so much of the functionality is neither exposed nor extensible.

Regards,
Bob.
