• How to give dynamic file name in the appender in log4j.xml

  - by Bittu

  Hi I am using log4j.xml to log the informations. I have used log4j.xml file for creating the log files. I have given the absolute path for each log file in param tag value. eg : appender name="FA" class="org.apache.log4j.DailyRollingFileAppender" param name="DatePattern" value="'_'yyyyMMdd"/ param name="File" value="D:/logFiles/GPreprocessor.log"/ layout class="com.dnb.genericpreprocessor.common.log.AppXMLLayout"/ /appender I do not want to give "GPreprocessor.log" directly.Actually that file name is dynamic based on my project. However the location will always remain same as "D:/logFiles/" . Please help me in this as this is very urgent and important for me.

• How does one use dynamic recompilation?

  - by acidzombie24

  It came to my attention some emulators and virtual machines use dynamic recompilation. How do they do that? In C i know how to call a function in ram using typecasting (although i never tried) but how does one read opcodes and generate code for it? Does the person need to have premade assembly chunks and copy/batch them together? is the assembly written in C? If so how do you find the length of the code? How do you account for system interrupts?

  - by lkessler

  I have a choice. I have an array of ordered strings that I need to store and access. It looks like I can choose between using: A TStringList A Dynamic Array of strings, and A Linked List of strings In what circumstances is each of these better than the others? Which is best for small lists (under 10 items)? Which is best for large lists (over 1000 items)? Which is best for huge lists (over 1,000,000 items)? Which is best tor minimize memory use? Which is best to minimize loading and/or access time? For reference, I am using Delphi 2009.

• Ajax dynamic content from .aspx page

  - by Nano

  Hi, I'm using this Ajax script (http://www.dhtmlgoodies.com/index.html?whichScript=ajax-dynamic-content) to load content from an aspx page on another server than the page calling the content. So far I've learned that this is a no go. The problem seems to be that when using an absolute link to content the script fails as apposed to using a relative link. I've searched the web for about 10 hours now, and I still haven't found what I'm looking for. I'm in need of some expert help here. Appreciate any help. Best regards Nano

• Adding dynamic controls to Silverlight application after WCF Service Asynchronous Callback

  - by Birk

  I'm trying to add some dynamic controls to my Silverlight page after a WCF call. When I try to add a control to I get an error: Object reference not set to an instance of an object. Here is a simplified version of my code: using edm = SilverlightBusinessApplication.ServiceRefrence; public partial class ListWCF : Page { edm.ServiceClient EdmClient = new ServiceClient(); public ListWCF() { EdmClient.GetTestCompleted += EdmGetTestCompleted; EdmClient.GetTestAsync(); } private void EdmGetTestCompleted(object sender, edm.GetTestCompletedEventArgs e) { //This is where I want to add my controls Button b = new Button(); LayoutRoot.Children.Add(b); //Error: Object reference not set to an instance of an object } } Is it not possible to modify the page after it has been loaded? What am I missing? Thanks

• iPhone: How to create dynamic image dragging ala iphone icon rearranging

  - by Jim Coffman

  On the iPhone, if you touch and hold your finger on an icon, it starts vibrating, then you can drag them around while the other icons move aside and rearrange dynamically. I'm trying to figure out how to do this inside an application with a grid of images or buttons. I don't need them to vibrate, but I do want the UI to allow the user to drag them with real-time dynamic reordering and then return the new position (ie, an int for accessing a mutable array). Any ideas how to do this? Any sample code out there? Thanks!

• dynamic silverlight content

  - by Jeremy

  I am starting a silverlight project where I have tests for students to complete. I want to have some sort of framework so I can build the tests and store them in a database, delivering the content dynamically so I can continually develop new types of tests without having to re-deply the application. The content will have to be more than just xaml, as there may need to be some logic to determine if answers are correct, or to do some random generation of questions. I'm looking for suggestions on how to go about building a framework that supports this. Are there some best practices, or examples? Should each test type just be a seperate silverlight control, or should I use 1 silverlight "container" application that can display dynamic content?

• Dynamic table design (common lookup table), need a nice query to get the values

  - by Swoosh

  sql2005 This is my simplified example: (in reality there are 40+ tables in here, I only showed 2) I got a table called tb_modules, with 3 columns (id, description, tablename as varchar): 1, UserType, tb_usertype 2, Religion, tb_religion (Last column is actually the name of a different table) I got an other table that looks like this: tb_value (columns:id, tb_modules_ID, usertype_OR_religion_ID) values: 1111, 1, 45 1112, 1, 55 1113, 2, 123 1114, 2, 234 so, I mean 45, 55, 123, 234 are usertype OR religion ID's (45, 55 usertype, 123, 234 religion ID`s) Don't judge, I didn't design the database Question How can I make a select, showing * from tb_value, plus one column That one column would be TITLE from the tb_usertype or RELIGIONNAME from the tb_religion table I would like to make a general thing. Was thinking initially about maybe a SQL function that returns a string, but I think I would need dynamic SQL, which is not ok in a function. Anyone a better idea ?

• How to handle concurrency control in dynamic data?

  - by Andrew

  I've been quite impressed with dynamic data and how easy and quick it is to get a simple site up and running. I'm planning on using it for a simple internal HR admin site for registering people's skills/degrees/etc. I've been watching the intro videos at www.asp.net/dynamicdata and one thing they never mention is how to handle concurrency control. It seems that DD does not handle it right out of the box (unless there is some setting I haven't seen) as I manually generated a change conflict exception and the app failed without any user friendly message. Anybody know if DD handles it out of the box? Or do you have to somehow build it into the site?

• Generating Dynamic web pages without server side scripting

  - by Microkernel

  Hi guys, I am trying to control a media device which has lot of multimedia content that it can play using another device(remote control device) like an ipad connected to the LAN. (UPnP) I want the media device to be able to send the content listing to the remote device so that it will be rendered as a webpage on the remote controller. And actions on the webpages needs to be sent to the the device as commands to execute (like play, pause, next etc). The media device is an embedded device, hence can't have any server side scripting, all has to be done on the client side. I want the page rendered to be HTML5. So, is it possible to generate dynamic HTML5 pages using just client side scripting? Thanks a lot. I am an embedded systems developer hence clueless about the web designing stuff.

• JQuery Validate Dynamic Table

  - by Richard

  I'm using the JQuery validation plug to validate my entire form. I also have a dynamic table on my registration page where the user can register more people. I can validate the rest of the form fine but my goal is to validate the table inputs just the same. Here is my jfiddle code: tables I don't know why the add line won't work there but it definitely works on my page. Anyway, that code ends up validate ONLY the first row of my table, but I want it to validate every single row. Can anyone see any problems with the code?

• Dynamic dispatch and inheritance in python

  - by Bill Zimmerman

  Hi, I'm trying to modify Guido's multimethod (dynamic dispatch code): http://www.artima.com/weblogs/viewpost.jsp?thread=101605 to handle inheritance and possibly out of order arguments. e.g. (inheritance problem) class A(object): pass class B(A): pass @multimethod(A,A) def foo(arg1,arg2): print 'works' foo(A(),A()) #works foo(A(),B()) #fails Is there a better way than iteratively checking for the super() of each item until one is found? e.g. (argument ordering problem) I was thinking of this from a collision detection standpoint. e.g. foo(Car(),Truck()) and foo(Truck(), Car()) and should both trigger foo(Car,Truck) # Note: @multimethod(Truck,Car) will throw an exception if @multimethod(Car,Truck) was registered first? I'm looking specifically for an 'elegant' solution. I know that I could just brute force my way through all the possibilities, but I'm trying to avoid that. I just wanted to get some input/ideas before sitting down and pounding out a solution. Thanks

• dynamic model is not loading fields

  - by Toby Justus

  I am using a dynamic model found on the forum of sencha. function modelFactory(name, fields) { alert(fields); return Ext.define(name, { extend: 'Ext.data.Model', fields: fields }); } I placed the alert(fields) to check what happens with the field because it was not working. I get this: [object Object],[object Object],[object Object] How can i change this into a correct way to use it in the fields? Is there a way to check if the model has been created? With Firebug or something? EDIT: i get this in firebug: [Object { name="ccuDesignation", type=null}, Object { name="wanNumber", type=null}, Object { name="carrierName", type=null}, Object { name="dataPackageName", type=null}, Object { name="simIccid", type=null}, Object { name="expiryTime", type=null}, Object { name="bytesRx", type=null}, Object { name="bytesTx", type=null}]

• Dynamic Programming resources in C?

  - by EsotericMe

  Hi everyone, I'll be writing the online Google test tomorrow as a fresher. Apparently, they definitely ask one problem on Dynamic Programming? Does anyone know of a good resource for collection of DP problems in C along with solutions? I know what DP is & have used it on an occasion or twice. However I feel to crack a DP problem in test, prior practice of typical problems will make it easier to approach. Any good resources or problem sets with solutions in C will be highly appreciated. Thanks.

• Dynamic where clause in LINQ - with column names available at runtime

  - by sandesh247

  Disclaimer: I've solved the problem using Expressions from System.Linq.Expressions, but I'm still looking for a better/easier way. Consider the following situation : var query = from c in db.Customers where (c.ContactFirstName.Contains("BlackListed") || c.ContactLastName.Contains("BlackListed") || c.Address.Contains("BlackListed")) select c; The columns/attributes that need to be checked against the blacklisted term are only available to me at runtime. How do I generate this dynamic where clause? An additional complication is that the Queryable collection (db.Customers above) is typed to a Queryable of the base class of 'Customer' (say 'Person'), and therefore writing c.Address as above is not an option.

• DataContext Doesn't Exist in Dynamic Data Project?

  - by davemackey

  This is really annoying...and I know it is something extremely simple... 1. I create a new Dynamic Data project. 2. I add a LINQ-to-SQL class and drag and drop some tables onto the class. 3. I open the global.asax.vb and uncomment the line: DefaultModel.RegisterContext(GetType(YourDataContext), New ContextConfiguration() With {.ScaffoldAllTables = True}) I remove YourDataContext and replace it with the DataContext from my LINQ-to-SQL class: DefaultModel.RegisterContext(GetType(NorthwindDataContext), New ContextConfiguration() With {.ScaffoldAllTables = True}) I then try to debug/build/etc. and receive the following error: Type 'NorthwindDataContext' is not defined Why is it not defined? It seems like its not recognizing I created the DBML file.

• Dynamic access to tables from another database inside an user function

  - by Alberto Martinez

  I have an user defined table function in SQL Server that aggregate data from several tables including a couple of tables of another database. That is done hardcoding the name of the database in the queries, but we want to make the database name configurable (because our databases usually share the server with the databases of other applications). I tried to construct a dynamic query string inside the function using the database name that is stored in a configuration table, but: When I tried exec(@sqlStatement) SQL Server said that execute string is not allowed inside a function. Then I tried exec sp_executesql @sqlStatement and the function was created, but when you execute it SQL Server says that inside a function you can only run extended functions and procedures. So the question is: is possible create a function or stored procedure that access a table in another database without having to recreate the function when the database name is different? TIA.
