• replace a text string

  - by shantanuo

  I want to replace the date found at the end of the "datadir" line with the current date. For e.g. my my.cnf file looks like this... # head /etc/my.cnf [mysqld] #mount -t tmpfs -o size=102m tmpfs /mnt #datadir=/mnt read-only datadir=/mysqlApr5 #datadir=/mysqlApr2 #datadir=/mysqlMar16 #datadir=/mysqlFeb25a Most of the lines are commented. I need to find the datadir line that is not commented and then replace the /mysqlApr4 with /mysqlApr20 datadir=/mysqlApr20 If it is possible I will like to comment the older datadir path. #datadir=/mysqlApr5 I can output the current date as: date '+%b%d' But I want to concat it with the word "/mysql" and replace or comment the current datadir line.

• Problem with truncation of floating point values in DBSlayer.

  - by chrisdew

  When I run a query through DBslayer http://code.nytimes.com/projects/dbslayer the floating point results are truncated to a total of six digits (plus decimal point and negative sign when needed). { ... "lat":52.2228,"lng":-2.19906, ... } When I run the same query in MySQL, the results are as expected. | 52.22280884 | -2.19906425 | Firstly, am I correct in identifying DBSlayer as the cause of this effect? (Or the JSON library it uses, etc.) Secondly, is this floating point precision configurable within DBSlayer? Thanks, Chris. P.S. Ubuntu 9.10, x86_64 Path: .

• Looking for how-to use UIGraphicsSetPDFContextURLForRect on iOS or Cocoa

  - by user1676332

  I'm playing to manipulate PDF on iOS (display but also and mostly generation). I wish to embed rectangular areas which act as "external" links (URLs like http://host.tld/path/file). Do you know where I can find an example(s) of how to use the UIGraphicsSetPDFContextURLForRect function? I find absolutly nothing on Internet. If I understand well, the only requirement is that the current graphic context should be PDF "type" and I think I respect this since, upstream, I call UIGraphicsPushContext why my PDF context as parameter (this was anyway required for methods like drawAtPoint: that I use also with success). I do not think it is important but just in case I specify that this DOES NOT take place in the drawRect: of a View subclass. You're quite right to say me unequivocally that I have "all wrong". The graphical environment is so sophisticated and rich in iOS that I assume to have not assimilated more than 1 or 2% for now. Thank you in advance.

• POST with HTTPBuilder -> NullPointerException?

  - by Stefan Kendall

  I'm trying to make a simple HTTP POST request, and I have no idea why the following is failing. I tried following the examples here, and I don't see where I'm going wrong.

• parsing string off a configuration using strtok in C

  - by Jessica

  in the configuration file i have entries similar to this one: filepath = c:\Program Files\some value Where the path can contain spaces and there are no quotes on that string. I tried parsing this with strtok like: char *option; char *value; value = strtok(line, " ="); strcpy(option, value); value = strtok(NULL, " ="); where line is the line I am reading from the file, option will contain the left side of the equal (filepath) and value will contain the right side (c:\program files\some value). I know, it's poor coding, but I haven't found something better. sorry... In any case, for those options where there's no space in the right side it works great, but in those containing spaces it only return the string until the 1st space: c:\Program. Is there any other way to do this? Code is appreciated. Jessica

• Binding the property to a control defined inside a listboxitem template

  - by Malcolm

  I have a class called ledgerObject : public class LedgerObject { public ChargeLine ChargeLine{ get; set; } public DelegateCommand Click_hyperbnCommand{ get; private set; } public LedgerObject() { this.Click_hyperbnCommand = new DelegateCommand(click_btn); } private void click_btn(object args) { } } The chargeLine which is the property of this class is itself a class and has some properties in it. So I am binding the datacontext of a listbox to an array of LedgerObject, and I want to bind the textblock control defined inside a listboxitem template to the property of a ChargeLine. Any idea or suggestion will help. I have tried this but not working: <TextBlock Margin="4 0 4 0" Grid.Column="3" Text="{Binding Path=ChargeLine.SimCode}" TextDecorations="Underline" Foreground="Red" />

• asp.net FileUpload control problem: access to directory is denied

  - by citrus

  Hi, Im trying to use the fileupload control. Im using Visual Web Developer Express on my desktop. My web application is working fine except I cant use the fileUpload control. I get the following error: ERROR: Access to the path (My_Directory) is denied I searched and it appears to be a permissions problem. So I attempted to add the user ASPNET and give appropriate permissions to the directory, however, I was unable to add user "ASPNET". User "ASPNET" was not found. So then I followed the following directions to add user ASPNET via Control Panel Administration Computer management. So now I was able to add user ASPNET to the directory and give appropriate permissions but I still got the above error. http://p2p.wrox.com/net-web-services/5918-creating-aspnet-user.html Any ideas on why I cant access the directory?

• Rails route rewriting quesiton

  - by Jonathan

  Hi guys, I think this is an easy question. I am using this useful Flash Document Reader called FlexPaper. I have it embeded in one of my Show pages. But when I click the a link on their tool bar to show the document in a new browser, it points to the following link ... http://0.0.0.0:3000/intels/FlexPaperViewer.swf?ZoomTime=0.5&FitPageOnLoad=false&PrintEnabled=false&SwfFile=%2FPaper.swf which doesn't work, but if I remove the "intels" from the path so the url looks like: http://0.0.0.0:3000/FlexPaperViewer.swf?ZoomTime=0.5&FitPageOnLoad=false&PrintEnabled=false&SwfFile=%2FPaper.swf It works fine. My question is what is the best way to handle this. Can you write a route that rewrites a url that starts with intels/FlexPaperViewer.swf and removes the intels prefix? What would that look like? Is there a better option? Thanks! Jonathan

• WinDbg can't find mfc90 version 9.0.30729.4148 symbols on msdl.microsoft.com

  - by Simon Hofverberg

  I think the title states my problem fairly well. Where are those mfc symbols? Some background info: I have a crash dump that I want to analyze in WinDbg. My symbol path contains msdl.microsoft.com/download/symbols (and it says h t t p first but I'm a new user here so I'm not allowed to write that twice. The 9.0.30729.4148 version seems to be installed by some Windows update When a dump contains an earlier version of mfc90, it is located by WinDbg on the Microsoft symbol server with the same settings. When I use !sym noisy, the output for mfc90.dll contains: SYMSRV: http://msdl.microsoft.com/download/symbols/mfc90.dll/4A596D4939c000/mfc90.dll not found The same thing happens on two different computers Edit: See my comments below. The symbols are present on the server, but WinDbg can't get them.

• What are the permissions I need?

  - by Eric

  My folder at: /usr/local/www/.ext_env_vars has a bunch of files in it that my app needs to read. The user is 'webapp' So, I changed the perms like so: chmod -R 400 .ext_env_vars chown -R webapp.webapp .ext_env_vars The application can't read these. However, when I chmod 777, they are read by the app. So, it isn't that I have a path problem. Seems to be permissions only. So, what would I have to do to the permissions to make webapp be able to read those files in the .ext_env_vars folder? Thanks Eric

• Processing files with C# in folders whose names contain spaces

  - by Nigel Ainscoe

  There are plenty of C# samples that show how to manipulate files and directories but they inevitably use folder paths that contain no spaces. In the real world I need to be able to process files in folders with names that contain spaces. I have written the code below which shows how I have solved the problem. However it doesn't seem to be very elegant and I wonder if anyone has a better way. class Program { static void Main(string[] args) { var dirPath = @args[0] + "\\"; string[] myFiles = Directory.GetFiles(dirPath, "*txt"); foreach (var oldFile in myFiles) { string newFile = dirPath + "New " + Path.GetFileName(oldFile); File.Move(oldFile, newFile); } Console.ReadKey(); } } Regards, Nigel Ainscoe

• How to set a global before PHPUnit's skeleton-test is run

  - by ministerOfPower

  We set a global in our prepend file used to form the path for our require_once calls. For example: require_once($GLOBALS['root'].'/library/particleboard/JsonUtil.php'); Problem is, when I run PHPUnit's skeleton test builder, the prepend file is not run, so the global is never set. When I run cd /company/trunk/queue/process; phpunit --skeleton-test QueueProcessView PHPUnit tries to resolve a require_once in QueueProcessView, but since the $GLOBALS['root'] is never set, I get a fatal error when including the required file. For example, to PHPUnit, what should be require_once(/code/trunk/library/particleboard/JsonUtil.php) is resolved as require_once(/library/particleboard/JsonUtil.php) Notice the missing root. Does anyone know if the skeleton-test code has some way to call PHP file before it is run? In this I could set my GLOBAL['root'] in this file. Any other creative solutions would be appreciated.

• PDF permissions management with ASP.NET - Timeout Issue

  - by Ryan Smith

  I have a website that has several PDF files. I need to have quite a few of them locked down with the standard ASP.NET authentication (in a folder with web.config that denies anonymous users). I set PDF files to get handled by the ASP.NET worker process and added: <add type="System.Web.StaticFileHandler" path="*.pdf" verb="*" /> to my web.config, but for some reason they hang when downloading. I've seen this issue before on an old server, and for the live of me I can't remember what I did to solve it. Does anyone have any idea? Thanks.

• What is a programmer's life like?

  - by Zee JollyRoger

  Imagine like an 8-hour long video of any "typical/average" programming job. What is it like? Before I get myself involved in that path, what can I expect? I am interested in gathering first-hand information and accounts of the typical life of a programmer. My goal is to grasp the fundamental concepts of working in the professional field of programming. I just want to "see" into what it is/means to come to an entry-level programming job and program. See what kind of skills, mentality, expectations, and such are required.

• strange Problem with WPF Textbox stringformat - Cursor moves back

  - by Emad

  I am using WPF 4.0 TextBox and binding. I am using StringFormat to format the number as currency. the XAML looks like this: <TextBox Text="{Binding Path=ValueProperty, ValidatesOnDataErrors=True, ValidatesOnExceptions=True, StringFormat={}{0:C}, UpdateSourceTrigger=PropertyChanged}"> </TextBox> Everything seems to work correctly except for a strange behavior: When for example a user types in 12: right after typing 1, the value in the textbox becomes $1.00 and the weird thing is the the cursor is moved to be between the $ and the 1. So when a user simply types in 12, the result becomes $21.00. How can I fix this strange behavior?

• How come the Name property is <Unknown> on a FileStream which uses handle constructors?

  - by Mikael Svenson

  Say you get a file handle from some outside DLL and instantiate a FileStream with it. It works just fine for reading and writing. Then you want the path and name of that handle and try to access the Name property of your FileStream object, and it returns 'unknown'. This is true for the constructors which takes file handles: public FileStream(IntPtr handle, ... public FileStream(SafeFileHandle handle, ... I know the short answer, because it's not implemented. The private field _fileName of FileStream is never assigned in those constructors. Seems the API to get the name from a handle involves more than one line of code, but I still think they could have bothered to include this. So the real questions is: Why haven't they? Or did they just forget?

• Creating share programmatically fails with error 9

I am passing a string and have tried to use an explicit string and I still get error 9. I am creating the share remotely rather than on local machine however. Not sure if that matter.

• VS2012 equivalent of Eclipse's default Ctrl-Shift-O?

  - by x3chaos

  I'm used to Java (in Eclipse), which has its import statements, but I'm writing a DLL in Visual C# (in Visual Studio 2012), which has its using statements. I'm used to Eclipse's default keyboard shortcut Ctrl-Shift-O, which updates the list of import statements in the Java perspective, deleting unused imports and adding necessary imports found on the build path. Is there an equivalent operation in VS2012 with VC#? I've just been selecting the word, opening the Office-style popup, and added the "using" statement that way, but it conflicts with my workflow (read: I'm lazy and I like having my shortcuts).

• Testing complex entities

  - by Carlos

  I've got a C# form, with various controls on it. The form controls an ongoing process, and there are many, many aspects that need to be right for the program to run correctly. Each part can be unit tested (for instance, loading some coefficients, drawing some diagnostics) but I often run into problems that are best described with an example: "If I click here, then here, then change this, then re-open the form, then click here, it crashes or produces an error" I've tried my best to use common code organisational ideas (inheritance, DRY, separation of concerns) but there never seems to be a way to test every single path, and inevitably, a form with several controls will have a huge number of ways to execute. What can I read (preferably online) that addresses this kind of issue, and is there a (non-generic) term for it. This isn't a specific problem I'm having, but one that creeps up on me, especially with WinForms.

• Include static file in JSP with variable filename on WebSphere 6

  - by cringe

  I'm struggling with including a static file into my JSPs on Websphere 6.0.2.17. I tried this: <% final String MY_DIR = ResourceBundle.getBundle("mybundle").getString("props.pages.wcm"); %> <% final String page = ResourceBundle.getBundle("mybundle").getString("page"); %> <% final String inc = MY_DIR + "/" + bonus; %> <%@include file="<%= inc %>"%> The path is /wcm/some/other/dir/page and I can happily print that out with out.write(inc). Unfortunatly the include (and the jsp:include) isn't including the file at all. There is no error message, but the content isn't included... The file is accessible via the browser though. Do I have to create a full JSP for this to work? I just need a HTML file.
