Hello Nigel.

Another Error found in TImageEnMView.OnDestroyImage.
you are calling the method OnDestroyImage After Destroying the Object

Please check this example

You can fix this error

Hi Wesley

That is not the case. OnDestroyImage is called immediately before freeing the object.

Hi Nigel.

you noticed an error with m_checkboxes.Free ();
because this object is first destroyed and then the Events OnDestroyImage are Called.

Runs and Closes This App will occur an Access Violation

Nigel I sent an email from the heart to help him in his advances

Hi Wesley

That issue is outside of ImageEn.

Change your ImageEnMView1DestroyIMage event to:
if assigned(m_checkboxes) then
  m_checkboxes.Delete(idx);


And your FormDestroy event to:
FreeAndNil(m_checkboxes);
