I don't know what's wrong with function TRegistry:GetKeyNames()

Hi,
Thanks for your giving directions.

Now my code looks like this,but it can't pass the compiler ,the
error message identify that there is same problem:
[C++ Error] getparameter.cpp(41): E2109 Not an allowed type.
the line 41 is :   if(!Reg->GetKeyNames(ListBox1->Items))
I can't understand the real meaning of the error message.
can you help me?
thank you very much.

void __fastcall TOKRightDlg1::FormCreate(TObject *Sender)
{
    TRegistry *Reg = NULL;
    try
    {
        Reg = new TRegistry;
        Reg->RootKey = HKEY_LOCAL_MACHINE;

        if(!Reg->OpenKey("\\SOFTWARE",false))
            ShowMessage("Error in Opening Key SOFTWARE");
        else
        {
              ListBox1->Columns=1;
              if(!Reg->GetKeyNames(ListBox1->Items))   //Have Error.
                 ShowMessage("Fuction GetKeyNames Occurs Error!");
              else
                {
                   ListBox1->Items->Add("test1");
                   ListBox1->Items->Add("test2");
                   ListBox1->Items->Add("test3");
                   ListBox1->Repaint();
                }
        }
    }

GetKeyNames returns void not bool.
So doing !GetKeyNames(..); is not allowed.
