Maybe this is a subtle way of saying you need to ensure your code is better commented

HAHA. Or maybe it's a trap to see how many pinheads need to lighten up. 
Really, I'm rather proud that I can't answer. I'm not about to blindly waste my time throwing in comments on everything just so those comments can fall out of sync just as fast as someone can checkout a file and make changes.
I will comment structures and operations when their meaning is not obvious by looking. And I will comment what changes occurred to the code and why. But, other than that it's all self-documenting code.

I think if you interviewed everyone who's bothered to answer so far, you'll find that almost none of them were aware that the poll is about the word "all" and has very little to do with the word "comment."
You should have at least added a final option of "There's nothing that I ALWAYS comment in my code" to give yourself a true comparative analysis, and to clarify the actual point of the poll.

you should have added a single other choice: "I never comment code". It would have emphasised the "All" choices and given those of us who write self-documenting code a way to vote.

I took all to mean 90% of the time  . Guess it's too late to change my vote now  . Well judging from everyone else's votes, I'm a bit slack at commenting.. but then I just don't see the point of commenting something that's already obvious. (Once I start commenting I spend half an hour just making sure it's understandable to a primary school student who's technical knowledge extends only as far as changing his phone's ringtone  ). Maybe I need to find that elusive "middle road"...

Agreed as I could not truthfully vote for a single item.

I do most of my comments in Complicated Logics (Nested Loops, Comma Separating a string etc.,)...
Apart from that I thinks its necessary to comment All classes, structs and interfaces and Member Variables
Avoiding variables like i, j, k and naming them with proper variable names (something like nEmployeeID) reduces the need of comment in most of the places...

Yea, agree to this. I comment *where necessary*, not where a specific scheme forces me to comment (that often lead to comments of the form "function X does X" when X itself is descriptive enough). Therefore I mostly comment on the algorithms and on what the code does, not on static structures.

I agree with you guys, I comment only parts of code that i think is complex and easy to miss if i return to it later. What's the point in commenting every single line of your code - in fact, its a bug on its own.

I cut down the amount of comments to just the bare minimum. Only member variables and stuff that's not obvious. Otherwise it's too hard to find the code from within the mass of comments

int i;
i = 2;
i *= 4;

But what about methods? It drives me nuts when I see a routine with no comment, especially if that routine has a name like "HandleAction" that tells you nothing.
I find it so easy to get into the deadly "I understand it therefor it should be obvious to everyone else" trap.

A better solution is using meaningful names, then you may not need the comment at all

I agree. If the methods and variables have poignant names, comments become superfluous and that's one less thing to update if the code is changed.
IMO, excessive commenting probably means the code is either of questionable quality, or the developer has a hard-on for comments.
I find the best way to write comments, is to re-visit classes after a few weeks (once I've forgotten the thought processes behind it all) and read it from a virgin perspective. That way, I'm more likely to place comments where really needed. The trick is reading it from someone else's point of view.

I have been known to do the same thing and often try to anticipate the need. Nothing like reading your old code and saying “why did I do that?” to see a comment is (was) required.

Ditto! It's also amazingly common to have wishy-washy names such as HandleAction. It can be OK when we're being very generic, e.g., in some kind of framework. but more often than not it's because the dev can't be arsed to think up a better name.
