Does anyone know of a free tool, similar to what is built into Visual Studio 2010 for managed code, that can do analysis of unmanaged, MFC C++ code and give metrics (lines of code, dependency or coupling, etc)?
I've been searching on Google for awhile, but really haven't been able to find anything that works. Thanks a ton!
Source Monitor is a good free tool tool for code metrics such as LoC and complexity and also produces kiviat graphs. But it does not have any depedency or coupling metrics.
Our SourceMeter tool can analyze your Visual C++ project and provide you all the information you asked for: metrics (lines of code, dependency, coupling, 60+ metrics altogether). The results are in standard CSV files, which you can easily open in e.g. spreadsheet editors.
I am not sure about free tool but one paid tool which is most comprehensive is IBM's Logiscope http://www-01.ibm.com/software/awdtools/logiscope/
Not free but QA-CPP does metrics like cyclomatic complexity and static analysis.
It's fairly complex to set up but they are pretty good on product support and regularly put out updates.

I have a huge project with a bunch of features. Each of these features are new to the product so I'm a bit worried how customers will perceive them. I'm wondering if there are tools out there that help me facilitate my features releases. Are there any analytic tools out there that let me measure which one is working and which isn't? I'm worried I might lose customers.
I believe there's no such universal tool for testing everything in everyone. However there are some work flows and methodologies which helps to ensure released functionality quality. For example writing some tests in software level with some schedule should help a lot.
I cannot provide any concrete guidance since every team takes practices which suits best their needs.

I am using Visual Studio and an external library that is commented in doxygen-style. Is there any way to display doxygen documentation in the editor tooltip like DocXML?
The VS plugin Visual Assist shows doxygen comments. From what I can see, it doesn't actually process them, but it shows doxygen comments (in their raw form) nevertheless.
There's a trial at their website.
Be warned, though. I have seen very few C++ programmers who tried it for a few days and were not begging their managers to buy it for them afterwards.
Not that I am aware of (though I'd love to hear if there is a solution, as doxygen format is much more readable than XML).
A "workaround" I can suggest is that my AtomineerUtils add-in can bulk-convert Doxygen format comments into DocXML, which is then picked up and used for Intellisense tooltips. (And Doxygen is able to read DocXml, so you keep most of that functionality too). Currently the conversion is a fairly simple one, but I'm working on some improvements at the moment that should make it much more flexible with respect to input comment formats.

What is the best open source example of a lightweight
Windows Application?
µTorrent is a small bit-torrent client, a really small one. It doesn't come with an installer, just a exe, you drop in your PATH somewhere. It's super lightweight and yet feature rich. Plus it is the work of one man. It's also closed-source.
Many people have been curious about how it has been written, and there are hints here and there about a custom library etc. But the question is, are there any programs with attributes like µTorrent that are available with source code--attributes like speed, small size, awesomeness.
Possible related question (/questions/9603/what-is-some-great-source-code-to-read), but think smaller than something like the Linux kernel.
Clarification: I don't want examples of bit-torrent source code, but anything which is used by tons of people (validation of awesomeness) and also fast, small and awesome!
I think you should take a look at Notepad++ if you want to see a feature-rich low-consumption of power software :)
Netcat
It's the program that started all of the curiousity behind networks and how things WORK.
Everyone's looked at this source code.
rTorrent is a lightweight, feature-rich, console-only open-source torrent client.
I like Frhed, a simple open-source Windows hex editor.
FRESHMEAT is a great place to start. There are lots of small open source programs available that you can study.
Examples:
XML-RPC specification.C implementation for Python. Its easy to learn and its fun.
Heapq [\Lib\heapq.py] , xml-rpc [\Lib\xmlrpc] and lots of other codes in Python library are very well written.

I have a large 95% C, 5% C++ Win32 code base that I am trying to grok.
What modern tools are available for generating call-graph diagrams for C or C++ projects?
Have you tried doxygen and codeviz ?
Doxygen is normally used as a documentation tool, but it can generate call graphs for you with the CALL_GRAPH/CALLER_GRAPH options turned on.
Wikipedia lists a bunch of other options that you can try.
Have you tried SourceInsight's call graph feature?
http://www.sourceinsight.com/docs35/ae1144092.htm
Good old cflow works fine for C. See here for an implementation.
Any decent static analysis tool should have this functionality (as well as all the other stuff that such tools do). Wikipedia has a good list of such tools.
Another group of tools that may be worth checking out are coverage tools. The call graph generated by the coverage tool will contain only the calls that actually take place during a run of the program. Initially this may be more helpful to you than a full call graph. I'm unable to make any suggestions on this for Windows, but for linux projects I highly recommend gcov and lcov.

I've been looking for a tool to extract exception information from a C++ program. The most wanted feature I'm looking for: I want to know all the exceptions that can be thrown from a function (which would include all the function that is called from that function recursively).
I've always thought that documenting errors and exceptions in particular is very hard (and takes a lot of effort to keep up to date). But if there is some way to automate that, it would be very helpful.
A tool for windows and Visual Studio would be preferred but not necessary, I could always work around that.
PC-Lint claims to do static exception analysis of C++ code.
Coverity is another static C++ code analysis tool that apparently informs you of unhandled exceptions.
AQtime claims to have exception tracing as part of its code analysis. Plus, they advertise Visual Studio integration.
Here is a list of several static code analysis tools.
DISCLAIMER: Working on this tool is my day job.
Its hard for me to write this without it looking like a sales pitch, so I apologise in advance.
As well as other analysis, QA C++ outputs the list of types that are thrown from the body of functions and the call tree. I believe that this would be all the information that you require.
EDoC++ (http://edoc.sourceforge.net) is another alternative.
