在哪里放置破坏功能

Question

呼啦。

我有一个关于放置'销毁功能'的问题。

全局：

HWND g_hInvisible = NULL;

HINSTANCE g_hInstance = NULL;

WinMain代码：

INT WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevious, LPSTR lpCmdLine,INT nShows)
{
    MSG msg = {0};

    WNDCLASSEXW wcMain = {0};

    wcMain.cbSize           = sizeof(WNDCLASSEXW);
    wcMain.style            = CS_SAVEBITS;
    wcMain.lpfnWndProc      = MainWindowProc;
    wcMain.hInstance        = g_hInstance;
    wcMain.lpszClassName    = L"MAINCLASS";

    RegisterClassEx(&wcMain);

HWND hMainWindow = CreateWindowEx(0, L"MAINCLASS", L"Main Class Window", WS_OVERLAPPEDWINDOW, 100, 100, 100, 100, NULL, NULL, g_hInstance, NULL);


    InvisibleWindowInit();

    InvisibleWindowTerminate(); // <<< PLACE HERE ?

    while (GetMessage(&msg, NULL, 0, 0))
    {
        TranslateMessage(&msg);
        DispatchMessage(&msg);
    }

    InvisibleWindowTerminate(); // <<< OR PLACE HERE ?

    return (int) msg.wParam;
}

InvisibleWindowInit的代码：

BOOL InvisibleWindowInit()
{
    WNDCLASSEXW wcInvisible = {0};

    wcInvisible.cbSize           = sizeof(WNDCLASSEXW);
    wcInvisible.style            = CS_SAVEBITS;
    wcInvisible.lpfnWndProc      = InvisibleWindowProc;
    wcInvisible.hInstance        = g_hInstance;
    wcInvisible.lpszClassName    = L"INVISIBLE";

    RegisterClassEx(&wcInvisible);

    g_hInvisible = CreateWindowEx(0, L"INVISIBLE", L"INVISIBLE", WS_OVERLAPPEDWINDOW, 0, 0, 0, 0, NULL, NULL, g_hInstance, NULL);

    if (g_hInvisible == NULL)
    {
        dError = GetLastError();

        return FALSE;
    }

    return TRUE;
}

InvisibleWindowTerminate的代码：

VOID InvisibleWindowTerminate()
{
    DestroyWindow(hInvisible);

    g_hInvisible = NULL;
}

我想在另一段代码中调用 InvisibleWindowTerminate

那么在消息循环之前或之后哪个地方更好？

谢谢。
