That depens on what your thread is actually doing.  There are times when
Synchronize() is warranted.

However, given your previous example, I would suggest re-writing the code
like this instead:


    TthreadTest *TestItThread = NULL;

    //Start Thread Button
    void __fastcall TForm1::Button1Click(TObject *Sender)
    {
        StopTest();
        TestItThread = new TthreadTest(Handle); // create and run the thread
    }

    ///Stop Button
    void __fastcall TForm1::StopCodeClick(TObject *Sender)
    {
        StopTest();
    }

    void __fastcall TForm1::::StopTest()
    {
        if( TestItThread )
        {
            TestItThread->Terminate();
            TestItThread->WaitFor();
            delete TestItThread;
            TestItThread = NULL;
        }
    }


    ///////////////Thread Code

    class TthreadTest : public TThread
    {
    private:
        HWND FWnd;
    protected:
        void __fastcall Execute();
        void __fastcall AfterConstruction();
    public:
        __fastcall TthreadTest::TthreadTest(HWND hWnd);
    }

    __fastcall TthreadTest::TthreadTest(HWND hWnd)
        : TThread(true), FWnd(hWnd)
    {
    }

    void __fastcall TthreadTest::AfterConstruction()
    {
        Resume();
    }

    void __fastcall TthreadTest::Execute()
    {
        HDC DC = GetDC(FWnd);

        for(int i = 0; ((i <= 300000) && (!Terminated)); ++i)
        {
            String S = i;
            TextOut(DC, 10, 10, S.c_str(), S.Length());
        }

        ReleaseDC(FWnd, DC);
    }
