I used Code Inspection to replace all occurrences of NULL by nullptr in my MFC code. However, I then noticed that still some occurrences are left. All those occurrences are within ASSERT macros, for example:
ASSERT(pointer != NULL); Are macros ignored by design or can this be fixed?
Kind regards,

I was able to fix an ASSERT like this with my code.
- Are the instances underlined but not fixed or they aren't even underlined?
- If you remove the ASSERT part from an instance where it fails, just for testing, does it start working?
- What version of Visual Studio and Visual Assist are you using?
- Can you please try creating a clean new win32 project and paste the below code to see if you can reproduce the problem there?
void func()
{
int* a;
a = NULL;
ASSERT(a != NULL);
}

I'm sorry for being unclear.
quote:

The NULL instances in the ASSERT statements are not even underlined.
quote:

If I remove the ASSERT, but leave its argument in the code, then the contained NULL gets properly underlined.
quote:
What version of Visual Studio and Visual Assist are you using?
VS 2012, VA 2212.

If I do that, then your code snippet works for me. However, it doesn't work if I copy it into my real project. I copied your code snippet at different locations in my project, but the NULL macro inside the ASSERT statement still doesn't get underlined. (The NULL in a = NULL; get properly underlined everywhere, though.)
I have no idea what might trigger this. If I can try out something more, please let me know.
Kind regards,

If you add a new, empty cpp file to your main solution, what happens when you add the test code to this file? I am wondering if the problem is file or solution dependent. From this thread:
https://forums.wholetomato.com/forum/topic.asp?TOPIC_ID=12897
some checks are dependent on your toolset / IDE. So if this is indeed solution specific, this might help to explain why. |

I added an empty new cpp file to my project. I pasted accord's code into it. I didn't see the blue underlines, because I got some red wiggly lines. I fixed those by adding #include "stdafx.h" to that file. Then the same problem occurred again.
I wasn't sure whether something in my stdafx.h could cause the problem, so I added accord's code into that file, directly behind #include <afxwin.h>. Still, the problem remained.
I have no idea what could make my solution so special. My project is a rather straight-forward dialog-based MFC application.
Kind regards,

| What is the definition of your ASSERT? Can you please press F12 to go to the definition of the ASSERT's #define and then copy-paste it here? Which file is it inside? A general library or are you using your own/custom ASSERT code, defined inside the solution? |

The ASSERT macro is defined in afx.h:
#define ASSERT(f) DEBUG_ONLY((void) ((f) || !::AfxAssertFailedLine(THIS_FILE, __LINE__) || (AfxDebugBreak(), 0))) So, it should be the standard MFC ASSERT.

| Is your active configuration Debug or Release? If it is Release then the ASSERT is preprocessed away so Code Inspection doesn't see it. |

Before I misunderstand what you mean by "active configuration", it's what I have selected in the following toolbar, right?
It doesn't seem to matter, what I enter here. Also Debug Win32 doesn't show the underlines.
Do I have to trigger some kind of reparsing after changing the configuration?
Kind regards,

No, it is automatically triggered.
Yes, this is what holedigger means by active configuration.
I was able to reproduce the problem when I've chosen "Release": the underline disappears and it reappears when I switch back to "Debug".
x64 was a good tip on your screenshot, but unfortunately it is not the trigger, x64 works for me in Debug.
From what I see, it's like Code Inspection has found a different ASSERT. I'll ask internally if there is a way to find out which ASSERT did it find. |

I don't know whether this is helpful, but if I hit Alt+G, then I get the following options:

The problem seems to be fixed for me with VA version 2217.

Code Inspection - NULL in ASSERT
