| | So I have recently come across `string.Format("{0, x}", "Word")` for aligning strings, with demonstration code that works fine in the CMD.

| | Has there been a change behind the scenes to how the posting rank is calculated, or have I just reverted to being a Junior Poster with 900+ posts for no reason? As know there are people at hjgher ranks with less posts.  |
| | Doing some revision for a university exam being sat at the end of the week. Got my head around most of the BigO stuff I think apart from calculating the BigO equations like the below. T(n) = 1000040 T(n) = 45n^2 + 3n/1000 + 18(log n) Could anyone explain the …  |

| | Been running a couple of article queries this morning. When running `http://www.daniweb.com/api/articles?forum_id=61` I encountered what looks like a bug. The 11th thread reply coming back in the query is the following: { "title":"please help me .........", "related":[ { "id":"" } ], "posters":[ { "id":"1098860" }, { "id":"46588" }, { "id":"1091071" … |

| |  Just noticed the above occur when replying to a thread. The original post is behaving normally but then all comment replies in all threads are not correct. A refresh didn't clear the issue and Pritaeas didn't see the whitespace in IE or Opera on his machine. |
| | Noticed the other week that once you cancel sponsorship (for whatever reason) that you lose all recognition of helping the site at all in terms of running costs. Can we introduce a 'Past Sponsor' badge or something along those lines so that those who have given but currently can't for … |
| | Firstly I would like to say this update is a visually pleasing one and much welcomed :) However, would it be possible to provide an option in individual user's controls to disable such functionality? I have found two downsides to it on my current work machine which partially impact the … |

| | Just noticed this while browsing an [article](http://www.daniweb.com/software-development/csharp/threads/451901/weird-boolean-operator-trouble), the text was first displaying like so:  However once I had expanded the 'Show Comments' it seems to straighten out to what it should be:  I am running Internet Explorer (Work laptop don't judge me!)

| | As much as I love watching (most definately not stalking -*shakes head*-) this when I have spare time at work. Would it be possible to add a drop down at the top which could isolate different sections of the website, for example only see activity occuring in the C# forum? … |
| | So after seeing the typing test Dani so kindly made the other day and put on the site I decided to kill some time writing a simple application to practice my typing on. I have a RTB containing the text which I'm highlighting as I go type letters to show … |
| | Not sure whether this is anything major or not but noticed it while trawling the source code of the site debating making a small app to monitor when post's replies are changed. There is an error occuring of: `FB.getLoginStatus() called before calling FB.init()` in all.js line 52. |
| | Just wondering as I've been caught by it twice now. It is intentional that after pressing the code button you can't close the code entry window without first entering some text? So if you accidently press it, it forces me to put a random one letter code block to then …  |
| | Afternoon all, I currently am loading an XSD file from a physical file into memory to validate an XML file. However on loading the file it is containing such escape characters as `\r\n` to keep the formatting the document was originally in. This then causes an exception when loading the … |
