Hello! There is a Bitmap *bm , and the task of my program is to constantly copy arbitrary (but within the limits of the bitmap) areas of this bitmap, and draw them

 Bitmap *bm=0; void Create() { if(bm) delete bm; bm=new Bitmap(...); //рисуем в битмап, здесь всё нормально Draw(); } void Draw(HDC hdc) { Graphics g(hdc); g.DrawImage(bm->Clone(...),...); //клонируем, рисуем //потом снова вызываем эту функцию, и снова }

The problem is that during the call to this function, the memory used by my program is constantly increasing, this is a memory leak, right?

In all forums, sites they write that GDI + objects are released themselves, but something is not noticeable. Maybe the error is not in this? What is there to do?

    Well, because you have such an obvious leak that you can miss it only if you close your eyes.

     auto clone = bm->Clone(...); g.DrawImage(clone,...); delete clone;

    See the example on MSDN: Bitmap.Clone ()

    • So you need to call delete only if allocated memory with help. new - Arthur Klochko

      @ArturKlochko, obviously new is called inside Clone() - ixSci Sept
