Hi,
I got two questions for programming with map point

1) is there a way to programmatically change the layer?
i'm using map point 2006 and i'm trying to make a button click that will change the layer from "Road Map" -> "Road and Data Map" and back

2) is there a way to tell if a "drawn object" (like a drawn rectangle) is selected?
my program has a "delete" button, but it is only used to delete drawn objects. so i was hoping to have the delete button disabled if nothing was selected and enabled if something was selected.

thank so much

Hi,

You can use SelectionChange event for yoiu second question. As for you first question, there is no layers in mappoint.

Oh! To change the map style, it's

axMappointControl.ActiveMap.MapStyle = MapPoint.GeoMapStyle.geoMapStyle____;

I used the SelectionChange to catch the selection change
I also used axMappointControl.ActiveMap.Selection to let me know if something was selected or not.
However, I'm not able to tell if the selection is a drawn object (which I want) or a selection of a label (City, State, landmark, etc...)

Hi,

You can check if the NewSelection argument is a Direction, Location, Pushpin, Shape, or Waypoint object. In your case you can take acton when it is a Shape object.

Sorry I have to ask this, but how to get get to the NewSelection argument?

I'm not sure what to call get the type of the selected object
axMappointControl.ActiveMap.Selection only gives me a System.__ComObject

Hi,

No problem. What is the programming language you do it ?

I'm using C#
This is what I have so far (it's not much)

private void axMappointControl_SelectionChange(object sender, AxMapPoint._IMappointCtrlEvents_SelectionChangeEvent e)
{
if (axMappointControl.ActiveMap.Selection == null)
{
// disable control
}
else
{
// enable control
}
}

Hi,

Code:

Shape shape = e.pNewSelection as Shape
if (shape == null)
    return;

does this help ?

Thanks Wilfried
The snippet worked

I have the following:

Code:

private void axMappointControl_SelectionChange(object sender, AxMapPoint._IMappointCtrlEvents_SelectionChangeEvent e)
{
  MapPoint.Shape shape = e.pNewSelection as MapPoint.Shape;
  if (shape == null)
  {
     // disable control
  }
  else
  {
    // enable control
   }
}
