The application is crashing when i move back from a child form to parent

  • 0

The application is crashing when i move back from a child form to parent form. It is giving

Process task abnormally terminated with exit code (PM_ASSERT_ERROR)

Crashed Appl Task Call stack

I think that if some thread is running in child form, the above crash occurs.
For EX: In the child form, i am downloading images using DecodeUrl(). when i go back to parent form, i am deallocating all the memory assigned for different objects and then i am removing the child form from app control, I think the image download thread is still active and causing the crash. Any idea how to handle this error?

    You are not supposed to remove UI controls explicitly. The framework does that for you.
