  • Why do I get Code Analysis CA1062 on an out parameter in this code?

    - by brickner
    I have a very simple code (simplified from the original code - so I know it's not a very clever code) that when I compile in Visual Studio 2010 with Code Analysis gives me warning CA1062: Validate arguments of public methods. public class Foo { protected static void Bar(out int[] x) { x = new int[1]; for (int i = 0; i != 1; ++i) x[i] = 1; } } The warning I get: CA1062 : Microsoft.Design : In externally visible method 'Foo.Bar(out int[])', validate local variable '(*x)', which was reassigned from parameter 'x', before using it. I don't understand why do I get this warning and how can I resolve it without suppressing it? Can new return null? Is this a Visual Studio 2010 bug?

  • Querying and ordering results of a database in grails using transient fields

    - by Azder
    I'm trying to display paged data out of a grails domain object. For example: I have a domain object Employee with the properties firstName and lastName which are transient, and when invoking their setter/getter methods they encrypt/decrypt the data. The data is saved in the database in encrypted binary format, thus not sortable by those fields. And yet again, not sortable by transient ones either, as noted in: http://www.grails.org/GSP+Tag+-+sortableColumn . So now I'm trying to find a way to use the transients in a way similar to: Employee.withCriteria( max: 10, offset: 30 ){ order 'lastName', 'asc' order 'firstName', 'asc' } The class is: class Employee { byte[] encryptedFirstName byte[] encryptedLastName static transients = [ 'firstName', 'lastName' ] String getFirstName(){ decrypt("encryptedFirstName") } void setFirstName(String item){ encrypt("encryptedFirstName",item) } String getLastName(){ decrypt("encryptedLastName") } void setLastName(String item){ encrypt("encryptedLastName",item) } }

  • Include at text file as is in (Python) Sphinx Docs

    - by Gregg Lind
    (using Python-Sphinx Documentation tool) I have a .txt log file I'd like to build into _build/html unaltered. What do I need to alter in conf.py, index.rst, etc. Here is the layout: src/ index.rst some_doc.rst somefile.txt How do I get somefile.txt into the html build? I tried adding a line like this to index.rst: Contents: .. toctree:: :maxdepth: 2 some_doc "somefile.txt" hoping it would work by magic, but no magic here! Assuming this is even possible, what would I put in some_doc.rst to refer/link to that file? Note Yes, I'm aware I could put it in /static and just be done with it, but that seems like a total hack, and ugly.

  • Object reference error even when object is not null

    - by Shrewd Demon
    hi, i have an application wherein i have incorporate a "Remember Me" feature for the login screen. I do this by creating a cookie when the user logs in for the first time, so next time when the user visits the site i get the cookie and load the user information. i have written the code for loading user information in a common class in the App_Code folder...and all my pages inherit from this class. code for loading the user info is as follows: public static void LoadUserDetails(string emailId) { UsersEnt currentUser = UsersBL.LoadUserInfo(emailId); if (currentUser != null) HttpContext.Current.Session["CurrentUser"] = currentUser; } Now the problem is i get an "Object reference" error when i try to store the currentUser object in the session variable (even though the currentUser object is not null). However the password property in the currentUser object is null. Am i getting the error because of this...or is there some other reason?? thank you

  • How can I give a variable to an action listener?

    - by Roman
    I have a static variable partner in the class. And I want to set a value of these variable whenever a radio button is pressed. This is the code I tried to use: for (String playerName: players) { option = new JRadioButton(playerName, false); option.addActionListener(new ActionListener(){ @Override public void actionPerformed(ActionEvent evt) { partner = playerName; } }); partnerSelectionPanel.add(option); group.add(option); } The problem here is that the actionPerformed does not see the variable playerName created in the loop. How can I pass this variable to the actionListener?

  • GCJ Creates duplicate dummy symbol

    - by vickirk
    Hi, I'm trying to build a java application with gcj but getting the error below. multiple definition of `java resource .dummy' gcj versions are 4.4.1 on Ubuntu and 4.3.4 on cygwin/windows XP and I'm building it with gcj --main=my.MainClass --classpath=my my/*java Anyone seen this or know a workaround without installing an earlier version of gcj. If that is the way to do it does anyone know how to do that on cygwin or will I have to build it? Here is a minimal test case that gives this error public class A { public static void main(String[] args) { System.out.println(new B()); } } public class B { public String toString() { return "Hello"; } } gcj --main=A src/A.java src/B.java

  • Choosing between YUI Charts or Google Visualization API

    - by r2b2
    Hello , I'm a bit stuck with which charting library I will use in my project. Im stuck with this two (but also open for other suggestions) For YUI Charts : Pro : - Very robust and configurable Cons : - Uses flash 9 , which might potentially be inaccessible for users without up to date flash version - Does not support export to image (for flash versions < 10 only) For Google Visualization API pros: - small file size for the libraries, - can be exported to static image charts (via separate API call) Cons - limited configuration options So there, please help me decide. YUI charts has the edge over configuration options but Google Visualization API has the edge in terms of accessibility as it uses SVG to render the grapsh instead of Flash. For users that are hand-cuffed by corporate IT prohibitions , they cant just upgrade their Flash version and the page will not work. Thanks!

    How to make a screenshot of program window using WinAPI & C#? I sending WM_PAINT (0x000F) message to window, which I want to screenshot, wParam = HDChandle, but no screenshot in my picturebox.

  • How can I capture multiple matches from the same Perl regex?

    - by Sho Minamimoto
    I'm trying to parse a single string and get multiple chunks of data out from the same string with the same regex conditions. I'm parsing a single HTML doc that is static (For an undisclosed reason, I can't use an HTML parser to do the job.) I have an expression that looks like: $string =~ /\<img\ssrc\="(.*)"/; and I want to get the value of $1. However, in the one string, there are many img tags like this, so I need something like an array returned (@1?) is this possible?

  • ListView in ArrayAdapter order get's mixed up when scrolling

    - by Dan B
    Hi, I have a ListView in a custom ArrayAdapter that displays an icon ImageView and a TextView in each row. When I make the list long enough to let you scroll through it, the order starts out right, but when I start to scroll down, some of the earlier entries start re-appearing. If I scroll back up, the old order changes. Doing this repeatedly eventually causes the entire list order to be seemingly random. So scrolling the list is either causing the child order to change, or the drawing is not refreshing correctly. What could cause something like this to happen? I need the order the items are displayed to the user to be the same order they are added to the ArrayList, or at LEAST to remain in one static order. If I need to provide more detailed information, please let me know. Any help is appreciated. Thanks.

  • Strange execution of get accesor in c#?

    - by Kenji Kina
    I set up a simple program just to test how the code inside a get accessor executes (since I had been having some issues in another project), and found something quite strange: class Program { static void Main(string[] args) { var test = new TestClass(); var testBool = test.TestBool; } } public class TestClass { private bool _testBool = true; public bool TestBool { get { if (_testBool) { Console.WriteLine("true!"); } else { Console.WriteLine("false! WTF!"); } _testBool = false; return _testBool; } } } I expected the output to be true! But what I got instead was true! false! WTF! Just what is going on here?

  • using C function in C#

    - by andrew
    i have a dll, built with mingw one of the header files contains this: extern "C" { int get_mac_address(char * mac); //the function returns a mac address in the char * mac } I use this dll in another c++ app, built using Visual C++ (2008SP1), not managed, but plain c++ (simply include the header, and call the function) But now I have to use it in a C# application The problem is that i can't figure out how exactly (i'm new in .net programming) this is what i've tried public class Hwdinfo { [DllImport("mydll.dll")] public static extern void get_mac_address(string s); } When i call the function, nothing happens (the mydll.dll file is located in the bin folder of the c# app, and it gives me no errors or warnings whatsoever)

  • using Mutex causing application to hang on Win XP X64

    - by Mohsan
    hi. I used the following code to verify the single instance of application. On Win XP X86 it is working fine, but on X64 after 3 to 4 minutes System generates StackOverflowException and causes the application to hang. after removing this check application is working fine.. Please tell me what should be the reason. code is static void Main() { bool instanceCountOne = false; using (Mutex mtex = new Mutex(true, "AppName", out instanceCountOne)) { if (instanceCountOne) { #if (DEBUG) RunInDebugMode(); #else RunInReleaseMode(); #endif mtex.ReleaseMutex(); } else { MessageBox.Show( "An application instance is already running", "App Name", MessageBoxButtons.OK, MessageBoxIcon.Information); } } } it crashes when single instance of application is running.

  • CSS - Could use some pointers on correct positioning

    - by Kenny Bones
    Hi, I'm in need for some pointers on positioning. I've got this square which should be centered on the page. And with a logo and a logo font image kinda wrapped around the square. Now, I want this as dynamic as possible, because I use both the square and images elsewhere as well. So I can't really use stiff static positioning. This is the site: www.matkalenderen.no How should I do this? I want to logo to appear on the left side of the square. And the font to appear above the square. And the square itself should be centered. You probably get the picture :) Right now I've got a wrapper around everything, which is also centered.

  • What threading analysis tools do you recommend?

    - by glutz78
    My primary IDE is Visual Studio 2005 and I have a large C/C++ project. I'm interested in what thread analysis tools are recommended. By that I mean, I want a tool, static or dynamic, to help find race conditions, deadlocks, and the like. So far I've casually researched the following: 1. Intel Thread Checker: I don't believe that it ties into VS 2005? 2. Valgrind/Helgrind: free. 3. Coverity: this is a costly tool if i understand correctly. Anyone have experience with any of these or other? I'd much appreciate any advice. Thank you.

  • Logging a specific package in log4j programmatically

    - by VinTem
    Hi there, here is the thing, I have to deploy a web app and the the log4j.properties file is created by the client so I dont have control over it. Their properties file is like this: log4j.rootCategory= FILE !-----------FILE--------------! log4j.category.FILE=DEBUG log4j.appender.FILE=org.apache.log4j.RollingFileAppender log4j.appender.FILE.File=${catalina.base}/logs/rcweb.log log4j.appender.FILE.MaxFileSize=1024KB log4j.appender.FILE.MaxBackupIndex=10 log4j.appender.FILE.layout=org.apache.log4j.PatternLayout log4j.appender.FILE.layout.ConversionPattern=%-2d{dd/MM/yyyy HH:mm:ss} [%t] %5p %c:%L - %m%n And in my classes I do something like this: private static final Logger LOG = Logger.getLogger(MaterialController.class); LOG.info("my log"); But the log file has never been created. I did the test and changed the log4j.properties file and deployed in my computer adding the following line: log4j.logger.br.com.golive.requisicaoCompras=DEBUG This works, but I cant use the file like this. Is there any ideas? Thanks

  • JavaDoc to (Doku)Wiki conversion / doclet

    - by gamma
    Our company has a very large public Java API which is currently being released standalone and online using (of course) JavaDoc. It is surrounded by product documentation which links into the API. We are moving our static documentation to DokuWiki - which works pretty good - and want to keep the links. Now it would be good to have a method (or doclet) that exports the JavaDoc directly into DokuWiki - or a very near alternative. Question: Is there something like this or do you know a method to do just that?

  • HttpWebRequest timeout in Windows service
