Error message in MS visual c++ 6.0

[Anderson Jogie]

I am running a VC++ application, got a fatal error, clicked on the debug button, and the debugger open to this page which I have some problem understanding. Will like to get some help on how to interpret this error message. Thanks much. :) RDLLocation *GetDemandLocation() { return pDemandLocation; //this is where the deburgger yellow arrow is pointing } - this 0xdddddddd - RDLLoObject {...} - RDLDatabaseObject {...} - TStreamableBase {...} __vfptr CXX0030: Error: expression cannot be evaluated loadStatus CXX0030: Error: expression cannot be evaluated - Name {???} m_pchData CXX0030: Error: expression cannot be evaluated - _destructCB {...} __vfptr CXX0030: Error: expression cannot be evaluated _enabled CXX0030: Error: expression cannot be evaluated _needToInvoke CXX0030: Error: expression cannot be evaluated _doorOpen CXX0030: Error: expression cannot be evaluated _srcObj CXX0030: Error: expression cannot be evaluated - _cbList {...} allocator {...} _Head CXX0030: Error: expression cannot be evaluated _Size CXX0030: Error: expression cannot be evaluated - _valueCB {...} __vfptr CXX0030: Error: expression cannot be evaluated _enabled CXX0030: Error: expression cannot be evaluated _needToInvoke CXX0030: Error: expression cannot be evaluated _doorOpen CXX0030: Error: expression cannot be evaluated _srcObj CXX0030: Error: expression cannot be evaluated - _cbList {...} allocator {...} _Head CXX0017: Error: symbol "" not found _Size CXX0030: Error: expression cannot be evaluated ulDisplayFlags CXX0030: Error: expression cannot be evaluated pLoadItemSet CXX0017: Error: symbol "CSet<RDLLoadItem,1>" not found pDemandLocation CXX0030: Error: expression cannot be evaluated pSupplyLocation CXX0030: Error: expression cannot be evaluated pProTransResSet CXX0017: Error: symbol "CSet<RDLString,1>" not found pTimeWindowSet CXX0017: Error: symbol "CSet<RDLShipmentTimeWindow,1>" not found - LoadRef {???} m_pchData CXX0030: Error: expression cannot be evaluated ShipmentDemandType CXX0030: Error: expression cannot be evaluated Demand1 CXX0030: Error: expression cannot be evaluated Demand2 CXX0030: Error: expression cannot be evaluated Demand3 CXX0030: Error: expression cannot be evaluated LoadRate1 CXX0030: Error: expression cannot be evaluated LoadRate2 CXX0030: Error: expression cannot be evaluated LoadRate3 CXX0030: Error: expression cannot be evaluated UnLoadRate1 CXX0030: Error: expression cannot be evaluated UnLo
