BEX error c0000417 VC++ and MFC

I had access, via a friend, to a vc++ code which has MFC components with AxisMediaControl object to stream and record videos from an IP camera.

Now I am a complete novice in MFC and VC++. But I was going through the code as I know some C++ and was trying out if I could catch some MFC. It was probably a wrong choice starting with a complex application.

But nevertheless, in brief the application has three AFX threads running, one to read I/O from a hardware, One which implements some logic based on these I/O inputs and one which looks for any change in configuration of these I/O pins - It has a shared memory open and reads if there is any content in that shared memory and saves the content as a file.

Based on the I/O this application and the second thread mentions starts playing then records video from an IP camera.

When I run the application after compiling in VS2010, it runs as a standalone application as an exe for some random time and then I see a BEX error.

I got this from the windows event logger. I am not pasting the code here as I wont be able to comprehend code related suggestions. Could anybody please give an idea on what situations can this error code occur. Where can I start to solve this error. I know this is unauthorized memory access error. But WHAT operation(s) could cause it? Please help.
