C#, why does Convert.ToBoolean("0") fail?

- by JL

I know that trying to convert string "0" to boolean will fail, I also know how to fix this, thanks to Jon Skeets answers on other questions. What I would like to know is WHY does C# not recognise "0" as a valid input for a boolean conversion, surely you could look at it like 0 = false, 1 = true, or even -1 = false and 0 = true, anyways, my logic tells me that it could be a valid input, so is there a very good reason why its not? My bet is old vb6 would be able to recognize the string input "0" as valid.

apache setup/directive question

- by tom smith

Hi. Trying to get my head around what I believe is a very basic question. Assume I want to have: http://www.cat.com, and http://www.dog.com and I want to have the cat.com, and dog.com come from "indexA.php", and "indexB.php" respectively... where indexA.php and indexB.php are in the same dir... thanks

Errors caught by WBT, but not BBT and vice versa

- by David Relihan

Hi Folks, Can you think of one type of error that might be found using White-Box testing, and one type using Black-Box testing. i.e. an error that would be found by one and not the other. For WBT there would null else statements, but what would you catch with BBT and not WBT??? BTW this question is just based on my own personal study - I'm not getting free marks out of this!!!! Thanks,

What's the best way to debug AJAX to PHP calls?

- by Jascha

I'm having a miserable time debugging one small function on my new project. Essentially I'm having a user log out via an AJAX call to my log out script on my server called "userfFunctions.php" I'm using AJAX so that I don't have the headache of writing more regex to match my mod_rewrites. Anyway, every so often, it seems as though my Post data just flat out dies and since the PHP is running behind the scenes, I feel like I have no way of finding out where the data flow is being disrupted. BTW This function works 19 hrs of the day. Here is the javascript function: function logOut(){ var data = new Object; data.log_out = true; $.ajax({ type: 'POST', url: 'http://www.mydomain.com/User_Validator', //<-- redirects to userFunctions.php data: data, success: function(data) { alert(data); // <-- a response is triggered but with no response data! } }); } the php side: if(isset($_POST['log_out'])){ echo 'alert this!'; } here is my awesome response:

javascript - shorten string to fit into a certain # of lines

- by Mala

Hi I have a string that must fit into a box, and must be at most 3 lines long. To shorten it, I plan to truncate it and end it with '...'. I could shorten it to a certain # of characters but if i make it look good with "wwwwwwwww [...] wwww" it won't look right with "iiiiiiiiiii [...] iiii". Is there some way I can shorten it by how much space the string would take up, as opposed to how many characters there are in a string without using a fixed-width font? Mala ps. Please no "simply create an image of '...' and overlay it over the end of the line" hacks or similar - I actually want to shorten the string to the appropriate length

Whats the python way for recursively setting file permissions?

- by Geoff

What's the "python way" to recursively set the owner and group to files in a directory? I could just pass a 'chown -R' command to shell, but I feel like I'm missing something obvious. I'm mucking about with this: import os path = "/tmp/foo" for root, dirs, files in os.walk(path): for momo in dirs: os.chown(momo, 502, 20) This seems to work for setting the directory, but fails when applied to files. I suspect the files are not getting the whole path, so chown fails since it can't find the files. The error is: 'OSError: [Errno 2] No such file or directory: 'foo.html' What am I overlooking here?

what dataprovider in flex (aside from ArrayCollection) will work for single, non-repeating XML nodes

- by Rees

hello, i asked this question before but haven't been able to get an answer.. i get the following error when i retrieve an XML that only has 1 node (no repeating nodes) from a PHP page and i try to store in an ArrayCollection. -When I have MORE than 1 "name" nodes...i do NOT get an error. TypeError: Error #1034: Type Coercion failed: cannot convert "XXXXXX" to mx.collections.ArrayCollection. this error occurs as the line of code: myList= e.result.list.name; I'm using this ArrayCollection as a dataprovider for a Component -is there an alternative I can use that will take BOTH single and repeating nodes as well as work as a dataprovider? Thanks in advance! code: [Bindable] private var myList:ArrayCollection= new ArrayCollection(); private function getList(e:Event):void{ var getStudyLoungesService:HTTPService = new HTTPService(); getStuffService.url = "website.com/asdf.php"; getStuffService.addEventListener(ResultEvent.RESULT, onGetList); getStuffService.send(); } private function onGetList(e:ResultEvent):void{ myList= e.result.list.name; }

How to pin "Visual Studio 2010 Documentation" shortcut to Windows 7 taskbar?

- by Chris W. Rea

I just installed Microsoft Visual Studio 2010 at home, on my Windows 7 PC. One of the items installed with VS2010 is "Microsoft Visual Studio 2010 Documentation". I like to have the documentation installed locally and at my fingertips, and so before had always added a shortcut for the help viewer to my Quick Launch toolbar. However, I'm not able to pin the new documentation to the Windows 7 taskbar. It's frustrating. Note carefully: When I launch "Microsoft Visual Studio 2010 Documentation" from the Start menu, it seems to perform two functions: First, it launches the "Help Library Agent", which is a local HTTP server from which the help content is served... similar to the local ASP.NET web development server. Second, it launches the default web browser against the localhost URL corresponding to the port on which the "Help Library Agent" is running, for example: http://127.0.0.1:47873/help/1-1444/ms.help?method=f1&query=msdnstart&product=VS&productVersion=100&locale=en-US ... in other words, the program doesn't leave behind an active foreground process that displays in the taskbar. So, I can't choose "Pin this program to taskbar" as one might do so with a typical program. How can I get a shortcut to "Microsoft Visual Studio 2010 Documentation" in the Windows 7 taskbar? Has anybody got a workaround for this?
