Raises variant exception based on HRESULT value.
procedure VarResultCheck(AResult: HRESULT); overload; procedure VarResultCheck(AResult: HRESULT; ASourceType: TVarType; ADestType: TVarType); overload;
VarResultCheck(HRESULT AResult); VarResultCheck(HRESULT AResult, TVarType ASourceType, TVarType ADestType);
Variants
VarResultCheck examines the HRESULT value returned by many variant routines. If AResult is S_OK, VarResultCheck does nothing. Otherwise, VarResultCheck attempts to map AResult to a variant exception and raise that exception. If VarResultCheck is unable to map AResult to a specific variant Exception, it raises EVariantError.
Specify ASourceType and ADestType when the operation involves conversion between two variant types.
EVariantError
