Hello everybody,
I have a little boring problem with the function Locate(IPoint point, double tolerence) of IDisplayList. It simply don't work. It returns always null what every the value of the tolerence. I have try with a tolerence of 100 or 0.0001), the return value is always null. This is my code snipped :
[PHP][...]
ICachedGraphicFeatureLayer cachedGraphicFeatureLayer = new ForceElementLayerClass() as ICachedGraphicFeatureLayer;
// Set the symbol size and SizeIsRatio properties of the layer.
IForceElementLayer forceElementLayer = cachedGraphicFeatureLayer as IForceElementLayer;
forceElementLayer.Size = forceElementSize;
forceElementLayer.SizeIsRatio = keepForceElementRatio;
ESRI.ArcGIS.Geometry.Point point = new ESRI.ArcGIS.Geometry.Point() {
X = -116.627464540677, Y = 35.606039469217
};
ICachedGraphic graphic = MoleUtilities.CreateMoleUnit("SFAPWMSA-------", null, point, 2);
ICachedGraphicFeatureLayer cachedGraphicFeatureLayer = layer as ICachedGraphicFeatureLayer;
cachedGraphicFeatureLayer.DisplayList.Add(graphic);
ICachedGraphicSelection selectionInfo = cachedGraphicFeatureLayer as ICachedGraphicSelection;
ISet set = cachedGraphicFeatureLayer.DisplayList.Locate(point, 100);
[...]

public static ICachedGraphic CreateMoleUnit(string SymbolIdCode, IPropertySet propSet, IPoint point, double Size) {
ICachedGraphic cachedGraphic = null;
IFEGraphic forceElementGraphic = null;
if (UnitGraphicFactory == null) {
Trace.WriteLine("FEGraphicFactory is null, can't continue with Unit Create!");
return null;
}
forceElementGraphic = UnitGraphicFactory.Make(SymbolIdCode);
if (forceElementGraphic == null) {
Trace.WriteLine("FEGraphicFactory failed to create Unit from selected SIC:"
+ SymbolIdCode + ", can't continue with Unit Create!");
return null;
} else {
// Debug.WriteLine("Created Unit from selected SIC: " + SymbolIdCode);
}
forceElementGraphic.Style = StyleForCreate;
IForceElement forceElement = new ForceElementClass();
forceElement.PropertySet = propSet;
forceElement.Shape = point;
forceElement.MessageString = SymbolIdCode;
forceElementGraphic.ForceElement = forceElement;
cachedGraphic = forceElementGraphic as ICachedGraphic;
IGeometry pGeo = point as IGeometry;
cachedGraphic.Size = Size;
cachedGraphic.Geometry = pGeo;
cachedGraphic.IsLocked = false;
return cachedGraphic;
}[/PHP]
Could you say me what's wrong with my code ?
