Called by the edit control when it needs to compare two markers by user-defined data.
This function is called by the edit control from CBCGPEditCtrl::FindMarkerByData and CBCGPEditCtrl::GetMarkerListByData methods. If you define your own types of markers and derive them from CBCGPEditMarker you can override CompareData for the custom comparison.
dwData | Specifies the data to compare with. |
