List<^>^ c++ [modified]

[Andrea Di Domenico]

Hello, I would to use the List type as shows below:

this->telecommandList->Clear();
pTelecommand^ telecommand = gcnew pTelecommand();
pMessage ^message = gcnew pMessage();

pField ^field = gcnew pField("Coherent Mode Select",1,"Coherency");
message->Fields->Add(field);

field->Name = "Not Used";
field->NumBits = 15;
field->Description = "Not Used";
message->Fields->Add(field);

telecommand->Messages->Add(message);
telecommand->SubAddress = 10;

this->telecommandList->Add(telecommand);

telecommandList is declared as List<pTelecommand^> ^telecommandList; Fields is declared as List<pField^> ^Fields; and Messages is List<pMessage^> ^Messages when I write:

field->Name = "Not Used";
field->NumBits = 15;
field->Description = "Not Used";

the first field added to message->Fields List change the value, because it is a pointer to field. how can i add more different field? I have another problem with the code below:

List ^tempCommand = gcnew List;

for each(pMessage ^mess in this->Messages)
{
	mess->EncodeMessage();
	tempCommand->Add(mess);
}
this->Messages = tempCommand;

in this case i have the same problem described above. thank you.

ref class Field
{
public:
String^ name;
int numBits;
String^ description;
};

ref class Message
{
public:
// Other members
List<Field^>^ fields;
};

ref class TeleCommand
{
public:
// other members
List<Message^>^ messages;
};

// then your list of commands
List<TeleCommand^>^ teleCommands;

I think this kind of datastructure will solve your issue, also these are handles to the reference, so you can add more items using the Add method like teleCommands->messages->Add( gcnew Message()) Thanks Radhakrishnan G.
