My problem is how do I release the memory allocated by _di_OrderContainer. //----------------------------------------------------------------------------- void clsXMLOrderFile::Load() { int i; clsOrder* lOrder; clsOrderList *tmpList; _di_OrderContainer XMLOrderContainer; _di_IXMLOrderTypeList XMLOrderList; _di_IXMLOrderType XMLOrder; try { try { // Create OrderList tmpList = new clsOrderList(); // Read TXMLdocument in memory XMLOrderContainer = LoadOrderList(FFileName); // Get Last key from the XML OrderList tmpList->LastKey = XMLOrderContainer->Get_KeyField(); // Get reference to XML (Template)OrderList XMLOrderList = XMLOrderContainer->OrderList; i = 0; while (XMLOrderList->Count > i) { // Get current XML Order XMLOrder = XMLOrderList->Get_Item(i); // Create new order lOrder = new clsOrder(); // Convert from XML to Order lOrder->FromXML(XMLOrder); // Add the order to the OrderList tmpList->AddOrder(lOrder); i++; } } catch(Exception *E) { try { Save(); Load(); } catch(Exception *E) { Application->MessageBox(E->Message.c_str(),"<?Error?>",MB_OK); } } } catch(...) { Application->MessageBox("Foutje","foutje",MB_OK); } GetDataRef()->Assign( tmpList ); delete tmpList; tmpList = NULL; lVersion = (long)StrToInt64Def(IFM->GetStatusUserToUser2Ref()->Value(FFileName),0L); } the XMLOrderContainer is created from this XML definition what is a list of orders and a max order nr (LastKey) init. <?xml version="1.0"?> <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:xdb="http://www.borland.com/schemas/delphi/6.0/XMLDataBinding"> <xs:element name="OrderList" type="OrderListType"/> <xs:complexType name="OrderListType"><xs:annotation> <xs:appinfo xdb:identifierName="OrderContainer" xdb:docElement="OrderList"/> </xs:annotation> <xs:sequence> <xs:element name="KeyField" type="xs:string"/> <xs:element name="Order" type="OrderType" maxOccurs="unbounded"><xs:annotation> <xs:appinfo xdb:identifierName="OrderList"/> </xs:annotation> </xs:element> </xs:sequence> </xs:complexType> <xs:complexType name="OrderType"><xs:annotation> <xs:appinfo xdb:repeated="True"/> </xs:annotation> <xs:sequence> <xs:element name="version" type="xs:string"/> <xs:element name="Orderid" type="xs:integer"/> <xs:element name="Name" type="xs:string"/> <xs:element name="State" type="xs:integer"/> <xs:element name="CountDownActive" type="xs:boolean"/> <xs:element name="Grade" type="xs:string"/> <xs:element name="InktJetTypeActive" type="xs:boolean"/> <xs:element name="InktTextText" type="xs:string"/> <xs:element name="CrackQuality" type="xs:integer"/> <xs:element name="DirtQuality" type="xs:integer"/> <xs:element name="BloodQuality" type="xs:string"/> <xs:element name="EggType" type="xs:string"/> <xs:element name="EggColor" type="xs:string"/> <xs:element name="SortFunction" type="xs:string"/> <xs:element name="EggStampActive" type="xs:boolean"/> <xs:element name="Amount" type="xs:integer"/> <xs:element name="PackType" type="PackType"/> <xs:element name="Lane" type="LaneType" maxOccurs="unbounded"/> <xs:element name="Progress" type="xs:integer"/> <xs:element name="ImageFile" type="xs:string"/> <xs:element name="ActiveLanes" type="xs:integer"/> <xs:element name="MachineOrderID" type="xs:integer"/> </xs:sequence> </xs:complexType> <xs:complexType name="PackType"> <xs:sequence> <xs:element name="ID" type="xs:string"/> <xs:element name="Name" type="xs:string"/> <xs:element name="Description" type="xs:string"/> </xs:sequence> </xs:complexType> <xs:complexType name="LaneType"><xs:annotation> <xs:appinfo xdb:repeated="True"/> </xs:annotation> <xs:sequence> <xs:element name="ID" type="xs:integer"/> </xs:sequence> </xs:complexType> </xs:schema> Back to top Remy Lebeau (TeamB) Guest Posted: Fri Mar 18, 2005 9:45 am    Post subject: Re: how to use an XML data structure created by the XML Data "Jochanan" <jvdniet (AT) hotmail (DOT) com> wrote Quote: how do I release the memory allocated by _di_OrderContainer.

Gambit that is what i thout but when i run my code with code guard and i scip this function it give me a difference of 60 less in my memory leaks and thos i want to have as close as possible to zero. When i get out of the function i expect the system to release the memory and that is not happening. do you have any other idea's.
