Hi,
if a free C function is used without a prototype declaration, VA underlines the name of the function in red and it is not available in 'Find References'. Basically,
static void
foo() {
}
void
bla() {
foo(); -- underlined in red
}
However, this works fine:
void foo();
static void
foo() {
}
void
bla() {
foo(); -- fine
}
Is this intended?
Kind regards,
Sven |

Which IDE and version of VA are you using?
I am not seeing any underlining problems using VS2008 and VA 1859, with the code placed into a .cpp file, and also into a .c file. |

VA_X.dll file version 10.6.1859.0 built 2011.10.02
DevEnv.exe version 9.0.30729.1 Professional
msenv.dll version 9.0.30729.1
Comctl32.dll version 6.10.7601.17514
Windows 7 6.1 Build 7601 Service Pack 1
8 processors (x86-64;
WOW64)
Does this help?
Regards,
Sven
PS: I will try to isolate the problem... |

I am using the same IDE, version of VA and OS as you. Using the following, renamed for clarity, test code, placed into a .cpp file:
static void
freeFunctionNoDeclaration() {
}
void
callingFreeFunctionHere() {
freeFunctionNoDeclaration(); // no underlining here
bananaInvalidVar = 2; // undefined variable
bananaInvalidFunc(); // undefined function
}
here is a screen shot showing what I am seeing:
alt-g on the function call freeFunctionNoDeclaration() works correctly, taking me to the function implementation.
Can you try this code in a new, blank file in your solution please. You could be seeing the effects of something further up the current file confusing VA. |

Hi,
you are right. After creating a new file in the solution and pasting your snippet, it works fine.
But, leaving VS and restarting, I see
i.e. the two undef var/function do not appear underlined. Odd?
OK, now I'm confused. After restarting VS, I navigated back to the original file that gave the trouble mentioned in the first post. All red underlines are gone. GotoImplementation now works, but FindReferences is still not working, although the function name is not underlined in red.
Maybe I am using the wrong settings?
Kind regards,
Sven

VA does not underline mistyped symbols when you first open a file. VA only starts underlining after you have edited the file. Adding and deleting a space is enough to trigger the underlining. This is an optimisation to speed up code browsing.
So this will explain why underlining seems to disappear and reappear when you restart the IDE.
When Find References is not working, what happens when you try to trigger Find References? Is Find References offered at all? If it is offered, does it run? If so, how many references does it find? |

OK, thanks for clarification.
Find References shows a dialog saying "Find References is not available because the symbol is unrecognized".
Also doesn't work with local variables as I have just seen in one file. For a different file in the same solution,
it works and shows all occurrences of the local variable in that function.
Regards,
Sven
PS: I wish I could be more specific. I find it hard to exactly reproduce these issues as certain actions like
restarting the IDE make VS work again in some cases. However, at other times, I see issues with VA and don't
know what led to them. |

Find References not working on a local variable is a good case to study, since it is quite clear cut. This sounds like a parsing problem, something has confused our parser. Probably something further up the file.
Try turning on:
VA Options -> Advanced -> Fonts and Colors -> Local symbols in Bold
this should give you some information, since if local symbols in some functions are no longer going bold, this helps to narrow down where the problem starts.
Also try looking at the Alt-m list and VA Outline for the problem file:
http://www.wholetomato.com/products/features/methods.asp
http://www.wholetomato.com/products/features/vaoutline.asp
If these start to give the wrong results after the 3rd function in the file, then this suggests this is where the problem code lies. One thing that I have seen confuse VA is unmatched brackets like this:
static void testUnmatchedBrackets
{
#if 0
{
{
#endif
}
but in your problem file the problem may be different. If you have a file where you can reliably reproduce the problem, and if you are able to send me the file for testing purposes, then I can have a look at it and try to find out what is causing the problems. I realise this is often not possible, but it is worth mentioning in case you can send me the file.
Please submit the files via the form:

including this thread ID or URL in the description, so we can match it up. |
