Failed to set domain when copying subtype

ChristineGo — Fri, 23 Nov 2012 15:00:16 GMT

Dear All,

I've written the following code trying to copy the subtypes of a feature class, but got the following error message in the set_Domain method, could anyone help point out what's wrong?

Error message: "This database does not support null default values."

Program:

    private bool copySubTypes(IFeatureLayer pFeatureLayer, IFeatureClass fgdbFeatureClass, IWorkspace fgdbWorkspace)
    {
                if (pFeatureLayer == null || pFeatureLayer.FeatureClass == null) return true;

                ISubtypes subtypes = (ISubtypes)pFeatureLayer.FeatureClass;
                ISubtypes fgdbSubTypes = (ISubtypes)fgdbFeatureClass;
                IWorkspaceDomains fgdbWSdomain = (IWorkspaceDomains)fgdbWorkspace;

                if (!subtypes.HasSubtype) return true;

                fgdbSubTypes.SubtypeFieldName = subtypes.SubtypeFieldName;

                IEnumSubtype enumsubtype;
                int subtypeCode;
                string subtypeName;

                IFields pFields = pFeatureLayer.FeatureClass.Fields;

                enumsubtype = subtypes.Subtypes;
                enumsubtype.Reset();
                subtypeName = enumsubtype.Next(out subtypeCode);

                while (subtypeName != null)
                {
                    fgdbSubTypes.AddSubtype(subtypeCode, subtypeName);
                    for (int iCnt = 0; iCnt < pFields.FieldCount; iCnt++)
                    {
                        string sFieldName = pFields.get_Field(iCnt).Name;
                        object defVal = subtypes.get_DefaultValue(subtypeCode, sFieldName);
                        if (defVal.ToString().Length > 0)
                        {
                            fgdbSubTypes.set_DefaultValue(subtypeCode, sFieldName, defVal);
                        }

                        IDomain pDomain = subtypes.get_Domain(subtypeCode, sFieldName);
                        if (pDomain != null)
                        {
                            IDomain fgdbDomain = fgdbWSdomain.get_DomainByName(pDomain.Name);
                            if (fgdbDomain == null)
                            {
                                return false;
                            }
                            else
                            {
                                fgdbSubTypes.set_Domain(subtypeCode, sFieldName, fgdbDomain);
                            }
                        }
                    }
                    subtypeName = enumsubtype.Next(out subtypeCode);
                }
            return true;
    }

Hello,

I think you may have accidently posted in the wrong forum?

Thanks,
