Requesting your support for fixing the issue.

Answer 1

probably your code corrupted internal structures, see a similar issue:

Can you reproduce when compiled for Debug and started from Visual Studio with Mixed Mode Debugging?

Answer 2

Hi there,

The exception code 0xc0000005 indicates a memory access violation.
According to the information you've provided, it looks like the OCX control you're using is performing an illegal access to the memory, therefore the system raised the exception and halted the program's execution.

Your computer may have a virus and the 0xC0000005 error informs that the system prevented execution of a malicious application. Try running an full system scan.

You can also try updating the BIOS and video drivers of the PC and try running the MFC applications.
