Please see the attached layer. I have used following code in the OnMouseDown event. my objective is to select the X_coor , and Y_coor field from the layer based on the arg.X and arg.y. however when i run this code than on a single click there are several values of the X_coor and Y-coor. I observed that the values of x_coor and y_coor fields in the associated attribute table of the layer is differ by in fifth or sixth significant digit. Actually this is my Time enabled data and I want to access it time in second corresponding to X-coor and Y-coor when the mouse is clicked. Any help........
IMxApplication pMxApp = null;
pMxApp = (IMxApplication)ArcMap.Application;
IMxDocument pMxDoc = null;
//pMxDoc = ArcMap.Document;
if (pMxDoc.SelectedLayer == null)
{
MessageBox.Show("There is no layer selected. First select a time-aware layer.");
return;
}
IMap pMap = pMxDoc.FocusMap;
IIdentify idft = null;
//mycode for enevelop
int Tolerance = 10;
Tolerance = pMxDoc.SearchTolerancePixels;
IPoint mypt = pMxDoc.CurrentLocation;
int X = arg.X;
int Y = arg.Y;

pDispTrans = pMxApp.Display.DisplayTransformation;
tagRECT pToleranceRect = new tagRECT();
pToleranceRect.left = X - Tolerance;
pToleranceRect.right = X + Tolerance;
pToleranceRect.top = Y - Tolerance;
pToleranceRect.bottom = Y + Tolerance;
IEnvelope pSearchEnvelope = null;
pSearchEnvelope = new EnvelopeClass();
pDispTrans.TransformRect(pSearchEnvelope, ref pToleranceRect, (int)(esriDisplayTransformationEnum.esriTransformPosition | esriDisplayTransformationEnum.esriTransformToMap));
// identify feature points of measurement
pSearchEnvelope.SpatialReference = pMxDoc.ActiveView.FocusMap.SpatialReference;
idft = (IIdentify)pMap.get_Layer(0);
IArray pidarray = null;
