[Unmanaged C++]
public: HRESULT Identify( ILocation * Location, AgESTKesriIdentifyType IdentifyType, ILayer * Layer, ITrackCancel * TrackCancel, IAgEsri3dIdentifyResult ** ReturnValue );

[Unmanaged C++]

public: HRESULT Identify(

   AgESTKesriIdentifyType IdentifyType, 

   ILayer * Layer, 

   ITrackCancel * TrackCancel, 

   IAgEsri3dIdentifyResult ** ReturnValue

);

Parameters

Location

Search location. The search location may not cross the international date line.

IdentifyType

Member	Value	Description
eIdentifyAll	0	Identify from all layers.
eIdentifyTop	1	Identify from top-most layer
eIdentifyVisible	2	Identify from visible layers
eIdentifySelectable	3	Identify from selectable layers
eIdentifySingleLayer	4	Identify from single layer

Layer

Target layer for identification (only required if IdentifyType is eIdentifySingleLayer).

TrackCancel

TrackCancel object.

Return Type

Returns a collection of features identified.

Remarks

Identify the features on the requested layers inside the specified location. The Layer parameter is only used for the eIdentifySingleLayer option, and you can pass null for the other options. You can also pass null for the TrackCancel parameter if you do not wish to be notified of the progress of the operation.

This method is used in STK to implement the Get Info Tool.
