Re: [Cpp-Programming] What does this mean in debugging?

Without the code, we can't tell you what's wrong.  It looks like you are trying to dereference a pointer which is equal to 0 ("null pointer").

In Visual Studio, go to debug-->exceptions, and check all the boxes.  Then run your program in debug mode; when it crashes, it should tell you what part of code is throwing the exception.

I am using VC++ express.  I am trying to write a bitmap editor and I
have been having all kinds of strage memory problems.  I use a few
pointers mainly the one that holds the array for bitmap bit data.
