  • Best practices for creating a logger library using log4net. Is

    - by VolleyBall Player
    My goal is to create a log4net library that can be shared across multiple projects. In my solution which is in .net 4.0, I created a class library called Logger and referenced it from web project. Now I created a logger.config in the class library and put all the configuration in the logger.config file. I then used [assembly: log4net.Config.XmlConfigurator(Watch = true, ConfigFile = "Logger.config")] When I run the web app nothing is getting logged. So I added this line of code in web.config <add key="log4net.Internal.Debug" value="true"/> which gave me debugging info and error information Failed to find configuration section 'log4net' in the application's .config file. Check your .config file for the and elements. The configuration section should look like: I moved the configuration from logger.config to web.config and everything seems to work fine. I don't want the log4net configuration in web.config but have it logger.config as a cleaner approach. The goal is to make other projects use this library and not have to worry about configuration in every project. Now the question is, How do I do this? What am I doing wrong? Any suggestion with code example will be beneficial to everyone. FYI, I am using structure map IOC to reslove the logger before logging to it.

  • jQuery: extend plugin question

    - by Fuxi
    hi all, i'm having this simple plugin code: (function ($) { $.fn.tWeb = function () { var me = this; me.var1 = "foo"; this.done = function() { return this; } return this.done(); }; })(jQuery); var web = new jQuery.fn.tWeb(); alert(web.var1); works nice - alert(web.var1) is giving me "foo". my question: would it be possible extending this plugin by simply including another .js which has more code? eg. that i could ask for web.var2 i previously used a prototype function and could "extend" it by simply adding another js-include which refered to it eg. like tWeb.prototype.newfunction = function() how could this be done with jQuery? thx

  • How do I effectively store a connection string in machine.config only?

    - by Scott Bedwell
    We are moving to an environment with multiple engines of MS SQL running on the same server (a test engine and a production engine). We also have separate test and production web servers, and would like for our asp.net applications to "magically" use the test database engine on the test web server and the production database engine on the production web servers. We would like to store the connection strings in machine.config rather than in web.config, but when we put it in machine.config, visual studio's IDE (particularly with datasets) does not recognize that the machine.config contains the connection. Does anyone know of a solution for displaying these machine.config connection strings in visual studio, or of a different solution that would accommodate for this? Thanks.

  • Spring 3.0 MVC mvc:view-controller tag

    - by gouki
    Here's a snippet of my mvc-config.xml <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/WEB-INF/views/"/> <property name="suffix" value=".jsp"/> </bean> <mvc:view-controller path="/index" view-name="welcome"/> <mvc:view-controller path="/static/login" view-name="/static/login"/> <mvc:view-controller path="/login" view-name="/static/login"/> I have the welcome.jsp on /WEB-INF/view/ directory and login.jsp on /WEB-INF/view/static/. This work for '/index' and '/login' paths. But I'm getting 404 response for '/static/login' when invoked from the browser. I'm expecting that '/static/login/' and '/login' should behave the same. What could be wrong here? Would appreciate any help. Thanks!

  • IN SQL operator in R-Shiny

    - by Piyush
    I am taking multiple selection for component as per below code. selectInput("cmpnt", "Choose Component:", choices = as.character(levels(Material_Data()$CMPNT_NM)),multiple = TRUE) But I am trying to write a sql statement as given below, then its not working. Neither it is throwing any error message. When I was selecting one option at a time (without mutiple = TRUE) then it was working (since I was using "=" operator). But after using "multiple=TRUE" I need to use IN operator, which is not working.

  • Strategies on synching data and caching data between iphone and server

    - by Blankman
    Say I have a TODO list iphone app, that can be edited/viewed from both a web application and the iphone application. When on the iphone, when a user views all his todo lists, or sub-items, I would think that each time the user views a particular list it shouldn't be hitting the web applications API every-time, but rather cache locally the values and only hit the web when things change. What strategies are there for this type of scenerio?

  • Where should test classes be stored in the project?

    - by limc
    I build all my web projects at work using RAD/Eclipse, and I'm interested to know where do you guys normally store your test's *.class files. All my web projects have 2 source folders: "src" for source and "test" for testcases. The generated *.class files for both source folders are currently placed under WebContent/WEB-INF/classes folder. I want to separate the test *.class files from the src *.class files for 2 reasons:- There's no point to store them in WebContent/WEB-INF/classes and deploy them in production. Sonar and some other static code analysis tools don't produce an accurate static code analysis because it takes account of my crappy yet correct testcase code. So, right now, I have the following output folders:- "src" source folder compiles to WebContent/WEB-INF/classes folder. "test" source folder compiles to target/test-classes folder. Now, I'm getting this warning from RAD:- Broken single-root rule: A project may not contain more than one output folder. So, it seems like Eclipse-based IDEs prefer one project = one output folder, yet it provides an option for me to set up a custom output folder for my additional source folder from the "build path" dialog, and then it barks at me. I know I can just disable this warning myself, but I want to know how you guys handle this. Thanks.

  • SELECT set of most recent id, amount FROM table, where id occurs many times

    - by Jon Cram
    I have a table recording the amount of data transferred by a given service on a given date. One record is entered daily for a given service. I'd like to be able to retrieve the most recent amount for a set of services. Example data set: serviceId | amount | date ------------------------------- 1 | 8 | 2010-04-12 2 | 11 | 2010-04-12 2 | 14 | 2010-04-11 3 | 9 | 2010-04-11 1 | 6 | 2010-04-10 2 | 5 | 2010-04-10 3 | 22 | 2010-04-10 4 | 17 | 2010-04-19 Desired response (service ids 1,2,3): serviceId | amount | date ------------------------------- 1 | 8 | 2010-04-12 2 | 11 | 2010-04-12 3 | 9 | 2010-04-11 Desired response (service ids 2, 4): serviceId | amount | date ------------------------------- 2 | 11 | 2010-04-12 4 | 17 | 2010-04-19 This retrieves the equivalent as running the following once per serviceId: SELECT serviceId, amount, date FROM table WHERE serviceId = <given serviceId> ORDER BY date DESC LIMIT 0,1 I understand how I can retrieve the data I want in X queries. I'm interested to see how I can retrieve the same data using either a single query or at the very least less than X queries. I'm very interested to see what might be the most efficient approach. The table currently contains 28809 records. I appreciate that there are other questions that cover selecting the most recent set of records. I have examined three such questions but have been unable to apply the solutions to my problem.

  • Single Sign On with 3 applications

    - by John H.
    I'm building three web applications in .NET that will all share a users database and login information. Lets pretend that application 1 is the "parent" application and applications "A" and "B" are the "child" applications. All users have to be logged into application 1 to have access to applications A and B. Authorization, Authentication, and MachineKey sections of all web configs are present and work correctly. I have the correct web.config settings in all applications to achieve Single Sign On except one problem remains: what do I put in the "loginUrl" attribute of the forms tag in Applications A and B. Assume that the url for the login to application 1 is "www.johnsapp.com/login.aspx" How can I get applications A and B to send the user back to application 1 for authentication using only settings in web.config?

  • How can I have a Windsor IoC container that can be shared amongst my classes but not shared across m

    - by Si Keep
    I am building a set of class libraries that produce office open xml based reports and I am using a static Windsor IoC container. My problem is that one possible entry point to the reporting system is via a web front end which means that the reporting systems static IoC Container is being shared amongst multiple web requests which causes exceptions as for each new request the reporting system is trying re-register components in Windsor that were already registered by an earlier request. I dont want to move the registration into the web app global.asax as my reporting system will no longer be stand-alone. How can I have a Windsor IoC container that can be shared amongst my reporting classes but not shared across multiple web requests?

  • Google Image search base url for non ajax usage

    - by Mikulas Dite
    I would like to use Google Image search, however I can't find the proper url anywhere. Examples always refer to the web search, not the image search. I do not want to use javascript, I need the iamge at server side. Please, do not simply post links to the API documentation, but preferably the url itself. (Or the missing url argument etc). http://ajax.googleapis.com/ajax/services/search/web This is a web search - no changing web to image/img doesn't work.

  • ASP.NET: how can I compile in DEBUG mode?

    - by Budda
    AFAIK, usual ASP.NET web site/web application switched on into DEBUG mode when web/app-config setting "compilation" has debug="false". But I don't clearly understand how it works. Let's consider example: I have <compilation debug="true" />. I've added the following line into "Page_Load" method: System.Diagnostics.Debug.WriteLine("Page_Load"); When I launched web-site in 'debug' mode (using F5 button) It put me 'Page_Load' into output window. Everything is ok so far. When I change application compilation mode into non-debug: Will it recompile everything for 'non-debug' mode? Is this enough to go into "production" environment with this change only? I guess, it should be enough for web-site that doesn't use other project. Otherwise, I would better switch whole configuration into "Release" mode. In this case EACH project will be recompiled in "Release" mode. Am I right? Could you please point me if something is wrong here? Thanks a lot!

  • Can this line of code really throw an IndexOutOfRange exception?

    - by Jonathan M
    I am getting an IndexOutOfRange exception on the following line of code: var searchLastCriteria = (SearchCriteria)Session.GetSafely(WebConstants.KeyNames.SEARCH_LAST_CRITERIA); I'll explain the above here: SearchCriteria is an Enum with only two values Session is the HttpSessionState GetSafely is an extension method that looks like this: public static object GetSafely(this HttpSessionState source, string key) { try { return source[key]; } catch (Exception exc) { log.Info(exc); return null; } } WebConstants.KeyNames.SEARCH_LAST_CRITERIA is simply a constant I've tried everything to replicate this error, but I cannot reproduce it. I am beginning to think the stack trace is wrong. I thought perhaps the exception was actually coming from the GetSafely call, but it is swallowing the exceptions, so that can't be the case, and even if it was, it should show up in the stack trace. Is there anything in the line of code above that could possible throw an IndexOutOfRange exception? I know the line will throw an NullReferenceException if GetSafely returns null, and it will also throw an InvalidCastException if it returns anything that cannot be cast to SearchCriteria, but an IndexOutOfRange exception? I'm scratching my head here. Here is the stack trace: $LOG--> 2010-06-11 07:01:33,814 [ERROR] SERVERA (14) Web.Global - Index was outside the bounds of the array. System.Web.HttpUnhandledException: Exception of type 'System.Web.HttpUnhandledException' was thrown. ---> System.IndexOutOfRangeException: Index was outside the bounds of the array. at IterateSearchResult(Boolean next) in C:\Projects\Web\UserControls\AccountHeader.ascx.cs:line 242 at nextAccountLink_Click(Object sender, EventArgs e) in C:\Projects\Web\UserControls\AccountHeader.ascx.cs:line 232

  • Should you use LAMP or Spring Framework ?

    - by gazzzz
    Recently, I've been exploring Java space, and came across Spring Framework. Is this a web app framework like CodeIgniter or Rails ? If so, is Springs used for developing enterprise web applications that runs on Java EE technology ? I am curious, why Spring is getting lot of attention. Isn't it a lot cheaper to simply use LAMP + CI or Rails to develop web application ? Can Spring be used to develop desktop applications ?

    - by rodnower
    Hello, we have some Setup Project wrote in Visual Studio 2008 in C# that installs and uninstalls services with ServiceInstaller class. When I install the services this don't get too much time, but when I uninstall with following code the process for each service get few seconds (and we have many services): ServiceInstaller si = new ServiceInstaler(); string path = string.Format("/assemblypath={0}", strServiceExecutablePath); string[] cmdline = { path }; InstallContext context = new InstallContext(string.Empty, cmdline); si.Context = context; si.ServiceName = strServiceName; si.Uninstall(null); Some one know why?

Error code:2 In description? From where I need to delete service manually for delete it complitely? Thank you for ahead.

  • Custom Control in ASP.NET C#

    - by Gal V
    Hello all, I created a simple custom control that only inherits from the Literal control, and doesn't have any extensions yet, code is empty. Namespace: CustomControls Class name: Literal : System.Web.UI.WebControls.Literal Next thing I do is registering this control in the aspx page as following: <%@ Register TagPrefix="web" Namespace="CustomControls" % (I read in few tutorials that this is one of the ways to register it, besides web.config etc.) After all, no intellisence for me, and worse- I get a parse error 'unknown server tag: web' when I try to run the page with the control in it. I used 'create new project' and not new website, in case this info is needed. What could be my problem? Thanks in advance.

  • [C# Thread] I'd like access to a share on the network!

    - by JustLooking
    Some Details I am working with VisualWebGUI, so this app is like ASP.NET, and it is deployed on IIS 7 (for testing) For my 'Web Site', Anonymous Authentication is set to a specific user (DomainName\DomainUser). In my web.config, I have impersonation on. This is how I got my app to access the share in the first place. The Problem There is a point in the the app where we use the Thread class, something similar to: Thread myThread = new Thread(new ThreadStart(objInstance.PublicMethod)); myThread.Start(); What I have noticed is that I can write to my logs (text file on the share), everywhere throughout my code, except in the thread that I kicked off. I added some debugging output and what I see for users is: The thread that's kicked off: NT AUTHORITY\NETWORK SERVICE Everywhere else in my code: DomainName\DomainUser (described in my IIS setup) OK, for some reason the thread gets a different user (NETWORK SERVICE). Fine. But, my share (and the actual log file) was given 'Full Control' to the NETWORK SERVICE user (this share resides on a different server than the one that my app is running). If NETWORK SERVICE has rights to this folder, why do I get access denied? Or is there a way to have the thread I kick off have the same user as the process?

  • Non-CDN hosted jQuery caused some strange behaviour

    - by kwokwai
    Hi all, I was using this JQuery in this download link, and included it in the head tag of a HTML web page: <script type="text/javascript" src="http://code.jquery.com/jquery-latest.js"></script> In a php web page, I got these few lines of codes: $.ajax({ url: 'http://mywebsite.com/site1/toavail/, type: "post", success: function(data) { // some more code here } }); When I tested the HTML page in IE 6, and 7, I saw the same warning message: "permission denied" When I tested it in Firefox 3, nothing was returned from the server web page. Later, I changed the JQuery source link to be: http://code.jquery.com/jquery-1.4.2.js I refreshed the web page, and I could saw the returned value then.
