hi to all , i have 2 enum on my IDL file : interface myInterFace { typedef enum RPTR_RETRACTBIN_STATUS { RPTR_RETRACTBIN_OK, RPTR_RETRACTBIN_FULL, RPTR_RETRACTBIN_HIGH, RPTR_RETRACTBIN_NOT_SUPPORTED, RPTR_RETRACTBIN_UNKNOWN }RPtrRetractBinStatus; ... HRESULT SyncRetract([out,retval] RPtrRetractBinStatus * status); } library myLIB { typedef enum RPTR_RETRACT_TRESHOLD { RPTR_THRESHOLD_RETRACTBIN_FULL, RPTR_RETRACTBIN_HIGH }RPtrRetractThreshold; ... dispinterface _IXFSReceiptPrinterEvents { properties : methods: HRESULT StackOK(RPtrRetractThreshold reason); }; ... } after compile i have this error ::>> redefinition : RPTR_RETRACTBIN_HIGH what is its solution ?(NOTE : i can not rename any enum members)

hi, i want to define an enum type variable on the Interface , so i have defined an enum within interface and then take a property from this enum, but have encountered with a compile time error !? what is my mistake and what is its solution? interface IXFSReceipt : IDispatch { enum RPtrResolution { RPTR_RESOLUTION_LOW, RPTR_RESOLUTION_MEDIUM, RPTR_RESOLUTION_HIGH, RPTR_RESOLUTION_VERYHIGH }; HRESULT Resolution([out, retval] RPtrResolution* pVal);<<<<<<<< ERROR1 HRESULT Resolution([in] RPtrResolution newVal); }; ERROR1 : error MIDL2025 : syntax error : expecting a type specification
