关于远程桌面控制出错的问题

Question

TMyClient = class(TWSocketClient)
protected
FScrSpy: TScreenSpy;
FPos: Integer;
FCmd: array[0..SizeOf(TCtlCmd) - 1] of Char;

    constructor TMyClient.Create(AOwner: TComponent);  //构造

begin
inherited Create(AOwner); //调用
OnDataAvailable := DataAvailable;
OnError := Error;
//
FScrSpy := TScreenSpy.Create;
FScrSpy.Socket := Self;
FPos := 0;
end;

destructor TMyClient.Destroy;
begin
if Assigned(FScrSpy) then
begin
FScrSpy.Terminate;
FScrSpy := nil;
end;
inherited;
end;

运行后，显示：incompatible types:'TWSocket' and 'TMyClient' 不兼容，如何修改。

FScrSpy.Socket := Self;

'Self'，该怎么修改呢？请各位大神指点一下。
