How to Select Feature by XY Location and Highlight it in ArcMap 9.3 programmatically?

[dgesridgesri]

Greetings,

I hope to find a solution to the following questions that I really need in my project:

1. How to find the feature under the mouse click (XY Coodinates) from a feature layer in ArcMap 9.3?


2. How to highlight (flash) a selected feature in ArcMap 9.3 using VB.Net?

Please advise....

can anyone suggest some ideas

here is my code for displaying the map in wpf.

can you please tell me the code to implement yours code in my project...

public void WorkIdentify()
        {
           IMxDocument doc =  ArcMap.Application.Document as IMxDocument;
            IActiveView activeView = doc.ActiveView;
            IPoint mouseLocation = GetScreenCoordinatesFromMapCoorindates(doc.CurrentLocation, activeView);
            System.Int32 x = (System.Int32) mouseLocation.X;
            System.Int32 y = (System.Int32) mouseLocation.Y;
           
            if (activeView == null)
            {
                return;
            }
            ESRI.ArcGIS.Carto.IMap map = activeView.FocusMap;
            ESRI.ArcGIS.CartoUI.IIdentifyDialog identifyDialog = new ESRI.ArcGIS.CartoUI.IdentifyDialogClass();
            identifyDialog.Map = map;

            //Clear the dialog on each mouse click
            identifyDialog.ClearLayers();
            ESRI.ArcGIS.Display.IScreenDisplay screenDisplay = activeView.ScreenDisplay;

            ESRI.ArcGIS.Display.IDisplay display = screenDisplay; // Implicit Cast
            identifyDialog.Display = display;

            ESRI.ArcGIS.CartoUI.IIdentifyDialogProps identifyDialogProps = (ESRI.ArcGIS.CartoUI.IIdentifyDialogProps)identifyDialog; // Explicit Cast
            ESRI.ArcGIS.Carto.IEnumLayer enumLayer = identifyDialogProps.Layers;
            enumLayer.Reset();

            ESRI.ArcGIS.Carto.ILayer layer = enumLayer.Next();

            //
            while (!(layer == null))
            {
                identifyDialog.AddLayerIdentifyPoint(layer, x, y);

                layer = enumLayer.Next();
            }
            identifyDialog.Show();
        }

Dear Sandhya Yamarthi,

Can you please tell me how to call the following code...

using System.Runtime.InteropServices;

namespace Project1

break;
}

{
FlashPolygon(MxDoc.ActiveView.ScreenDisplay, Feature.Shape);
break;
}
case (esriGeometryType.esriGeometryPoint):
{
FlashPoint(MxDoc.ActiveView.ScreenDisplay, Feature.Shape);
break;
}



}
MxDoc.ActiveView.ScreenDisplay.FinishDrawing();
}
catch (Exception Err)
{
MessageBox.Show("Error : " + Err.Message);

}

}

I have already post my code..

Thanks for your valuable time and consideration...

Waiting for your reply..
