TTreeView Items[i]->Data problem

Hello,
I have got a problem with C++ Builder 6 and this line :
for(int i = 0; i < MyTreeView->Items->Count ; i++)
(line 349) MyTreeView->Items[i]->Data = (void*) new MyStruct;
When I compile this line the message
[C++ Erreur] MainForm.cpp(349): E2288 Pointer on structure
needed on left side of ->or ->*
What could be the problem
Thanks for your answers.
Patrick

Re:TTreeView Items[i]->Data problem

It should be:
(line 349) MyTreeView->Items->Item[i]->Data = (void*) new MyStruct;
Items is a TTreeNodes pointer which contains a property Item. Check the help
for further details.
Yes, it's a bit confusing but...
