🚀 go-pugleaf

I didn't explained the code I send very well.
I delete the xmldocument allways.  After the catch there is a lot of code
that reads the xml.

If I put this in a button

 XMLDocument = new TXMLDocument("");
 delete XMLDocument;

it works....

but this trows an error at runtime:

    AnsiString Texto, Evento, Room_id;
    TXMLDocument *XMLDocument;
    _di_IXMLNode Nodo;

    XMLDocument = new TXMLDocument("");

    try
    {
      Texto = Socket->ReceiveText();
      Memo1->Lines->Add(Texto);

      try
      {
        XMLDocument->LoadFromXML(WideString(Texto));

        Nodo = XMLDocument->DocumentElement->ChildNodes->GetNode(0);  //here
        Evento = Nodo->Attributes[WideString("name")];
        (...)


I readed somewhere that this error happends because ther is a problem with
the sincronization or something like that.
so I use this code that works fine:

    AnsiString Texto, Evento, Room_id;
    TXMLDocument *XMLDocument;
    _di_IXMLDocument d;
    _di_IXMLNode Nodo;

    XMLDocument = new TXMLDocument("");

    try
    {
      Texto = Socket->ReceiveText();
      Memo1->Lines->Add(Texto);

      try
      {
        XMLDocument->GetInterface(d);
        d->LoadFromXML(WideString(Texto));

        Nodo = XMLDocument->DocumentElement->ChildNodes->GetNode(0);
        Evento = Nodo->Attributes[WideString("name")];

but i can not delete  XMLDocument.

I think that the problem in this line:  XMLDocument->GetInterface(d);

well... the problem is very strange...

I hope you can help me.
