Sorry, I should have included my main file aswell... This program had begun life as a Console project, then someone who didn't completely know what they were doing converted it to a Quickwin project by modifying a couple of compiler switches Apr 20, 2011 at 12:27pm UTC zlifanar (10) Sorry for tripple posting but: I removed the call to AddOptions() and it works fine, however then, when I end the program it Fiancée has a position lined up, but none of the universities in the area are hiring.
How do i go about "analyzing the instruction stream and registers"? The code mixes = and == and violates the Rule of Three, causing errors on copy. contact us current community chat Stack Overflow Meta Stack Overflow your communities Sign up or log in to customize your list. Thanks!
As I mentioned earlier, given the changeable behavior, it is very likely that memory is getting corrupted or perhaps your program is relying on uninitialized memory. But in DOS - this will be completely legal code and you will get some information from interrupt vector table (becouse IVT reside at this addresses) BTW, Even in Win32 - The third line attempts to grab the value of address 0, which is prohibited, and assign it to our variable “foo”. Exception Thrown Read Access Violation C++ An NT based operating system won't just throw an AV for OS reserved memory as well- if you try to access memory reserved by another application, the same error will apply.
IOW your array argument is invalid. I have no c functions being called (i had thought these were the problem previously). Just treat the pointers as boolean values, e.g. "if (glGenVertexArray) ....". 08-20-2013,02:28 PM #6 elfeck View Profile View Forum Posts Private Message Junior Member Newbie Join Date Jun 2013 Posts 20 And, 0x004173c8 is the arbitrary memory location where our application happened to be running at the time of the crash.
This usually occurs because a pointer has a bad value. 0xc0000005: Access Violation Reading Location 0x00000000. If you did not change any options, and by commenting out the test and call to DOSTOP reintroduces the error, then this leads to two possible suspects: a) Inserting the test Thanks app4619, i'll take a look into norm2 at some point. Please can someone share some insight on what I am doing wrong here?

So, Now i allocated a dedicated memory for my parameters and it is working fine. :) I should published it after solving my issue, but i forgot it. this contact form I hope that you have made sure of those interfaces being available.

Pointers in general are one of the most challenging topics in computer science, which is yet another reason this crash is so commonly seen. -Greg Comments (7) Cancel reply Name In looking at your disassembly code example, while I cannot conclusively confirm this, it appears that mecej4 may be onto something where you are calling a function who's interface was not The exact error message is: "Unhandled exception at 0x00D45446 in Project50.exe: 0xC0000005: Access violation reading location 0x00000014."

There seems to be more wrong with this code than there is right. –user657267 Sep 2 '14 at 4:55 1 Also, there is a doubly linked list in the standard Access Violation Reading Location 0xc0000005 Thus - while trying to read anything from this area (including from address 0) in user-mode Win32 process you will get page fault that will be translated to exception with code I think this is about dereferencing a null pointer.
There are further errors and instances of poor style. Does it resolve the problem? I ran the program in inspector, and i get a critical item "Unhandled application exception" and a "Invalid memory access" on the same line, but i don't see anything obvious that Exception Thrown: Write Access Violation Just if anyone was confused what "Watson" is: http://weblogs.asp.net/cflaat/archive/2003/07/24/51598.aspx Reply AT says: January 14, 2005 at 3:29 am Greg: A tiny correction to your comments.
Browse other questions tagged c++ class unhandled-exception doubly-linked-list or ask your own question. Using freeGlut and calling glewInit after the contex and window are created. NT-based OS will always throw exceptions if you try to access memory specialy protected from you (just like Win9X one ;-). Check This Out But that's not where your UB comes from (yet).
Also make a test run with gen-interfaces, check-interfaces. The article helps you indicate this problem: How Can I Debug an Access Violation?
