• The mobile application cannot connect to the web service

  - by cancelledout

  Hello everyone. I have a mobile app webservice client that connects to a WCF webservice(on my PC) deployed in a WiMo Device. The OS is Windows Mobile 6.0. It is connected to my PC using a USB cable and ActiveSync 4.5. Problem: When I use a mobile emulator to run the application, it was able to connect to the web service successfully. But if I use the mobile phone to run the application, it cannot connect to the web service. However, I can view the webservice's test webpage using phone's browser(IE) (http://153.xxx.xxx.xxx:8080/Design_Time_Addresses/SOAP11demo/Service1/) Can you guys help me identify on what is wrong?

• simple EJB jar deployed in jboss with its own log4j configuration

  - by user309281

  Hi All I have a simple EJB jar with a stateless session bean, deployed in JBOSS AS 4.2.2, unde r/server/default/deploy. The bean is registered under JNDI tree as viewed from jboss jmx console and I am able to access it through a remote java client outside JBOSS. Inside EJB jar, I have added some logging to be written to a separate log file, using apache log4j jar and log4j.xml. But I am not able to view any of the logs. Also I do not wish to use jboss-log4j.xml, since there will be many other EJBs to be deployed and wish to have separate log4j for each EJB application. Here is my one of the EJB-jar contents: EJB_DS.jar: log4j.xml classes apache log4j jar is added to /server/default/lib path. Kindly highlight if i have missed any points for enabling log4j configuration With Regards, Krishna

• Appengine (python) returns empty for valid queries

  - by Grant

  I've got an app with around half a million 'records', each of which only stores three fields. I'd like to look up records by a string field with a query, but I'm running into problems. If I visit the console page, manually view a record and save it (without making changes) it shows up in a query: SELECT * FROM wordEntry WHERE wordStr = 'SomeString' If I don't do this, I get 'no results'. Does appengine need time to update? If so, how much? (I was also having trouble batch deleting and modifying data, but I was able to break the problem up into smaller chunks.)

• Range validation not working properly in MVC3

  - by Colin Desmond

  I am generating data validation javascript in an Asp.Net MVC 3 application with the following code [DisplayName("Latitude Degrees")] [Range(0, 90, ErrorMessage = "Latitude degrees must be between {1} and {2}")] public Int32? LatitudeDegrees { get; set; } on a view model. When it was MVC2 this worked just fine, if I entered a value outside of 0-90 in the textbox I got the validation warnings. Since I moved the application to MVC 3, whenever I put any value into the texbox, legal or illegal I get the validation error appear next to it. I have EnableClientValidation set to true and UseUnobtrusiveJavascript is off (nothing in web.config or the views to turn it on).

• Differences setting content in Forms.WebBrowser control via DocumentText vs. Url

  - by jeffamaphone

  If I generate some HTML and have it in a string and then say: myWebBrowser.DocumentText = string; It seems to work just fine, except none of the images load (I get the broken image graphic). If, however, I write the string to a file and then say: myWebBrowser.Url = new Uri("file://myfile.html"); Everything works just fine. My question is, what's going on under the covers here that is different? I've verified in both cases that the path to the images (via RClick-View Source) is the same and that all the images do, indeed, exist. In both cases the HTML is exactly the same. Any light that could be shed on this would be appreciated. Thanks!

• iPhone: Using a Singleton with Tabview Controller and Navigation Controller

  - by malleswar

  Hi Friends, I have developed a small iPhone application by using singleton that I use to navigate through the views. Here is a sample method from my singleton class. + (void) loadMenuController:(NSMutableArray *)menuItems{ MenuViewController *menuViewControler = [[MenuViewController alloc] initWithNibName:@"MenuViewController" bundle:nil]; [menuViewControler setMenuItems:menuItems]; RootViewController *root = ( P2MAppDelegate *appDelegate = (P2MAppDelegate*) [[UIApplication sharedApplication] delegate]; UINavigationController *navController = [appDelegate navigationController]; [navController pushViewController:menuViewControler animated:YES]; [menuViewControler release]; } Now my requirement has changed to require a tab view controller . I could change my application delegate to a tabview controller but I still need to navigate inside each tab. I am unable get a clue how to navigate from my singleton class. Please guide me. Please let me know if my query is not clear. Thanks in advance. Regards, Malleswar

• Django User "per project" group assignation

  - by Ben G

  Hi, Here's my problem : my site has users, which can create projects, and access other user's projects. Each project can assign different rights to users. So, i could have Project A : user "John" is in group "manager" , and Project "B" user "John" is in group "worker". How could I use the Django User authentication model to do that ? From a SQL point a view, what i would like is to be able to add "project_id" in the primary key for the "auth_user_groups" table. I don't think profile is of any help here. Any advice ? UPDATE : "worker" and "manager" are just two examples of the permission group (or "roles") that my application defines. There will be more in the future. Eg : i will probably also have "admin", "reporting", etc...

• Tab versus space indentation in C#

  - by Lars Fastrup

  I sometimes find myself discussing this issue with other C# developers and especially if we use different styles. I can see the advantage of tab indentation allowing different developers to browse the code with their favorite indent size. Nonetheless, I long ago went for two space indentation in my C# code and have stuck with it ever since. Mainly because I often disliked the way statements spanning multiple lines are sometimes messed up when viewing code from other developers using another tab size. Recently a developer at one of my clients approached me and asked why I did not use tabs because he preferred to view code with an indentation size of 4. So my question is: Which style do you prefer and why?

• How to isolate data per customer, Django powered website

  - by Sawwy

  I have recently started learning python and django and working on a project that includes building a website for collecting information from customers. I am currently trying to figure out best way to isolate the customer data (collected information is sensitive and should only be accessible by customer and the service provider). I found this post Postgresql - one database for everyone, or one-database per customer and my question is that can I automate the model inheritance with customer creation via admin? To be specific, when save() is called for adding customer via django admin, this should create the customer specific tables (create a new set of tables with 'company_name' -prefix). For more information of the environment, I have extended the basic user registration with custom UserProfile adding 'company' and 'role' fields for each user. Upon login, the 'company' of the user will be checked to filter out tables without the 'company_name' prefix. 'Role' will further filter the which company-specific tables and set rights (view, edit). will appreciate any suggestions if more elegant methods could be used to solve the data isolation problem than model inheritance.

• Rails - Format number as currency format in the Getter

  - by daemonsy

  I am making a simple retail commerce solution, where there are prices in a few different models. These prices contribute to a total price. Imagine paying $0.30 more for selecting a topping for your yogurt. When I set the price field to t.decimal :price, precision:8, scale:2 The database stores 6.50 as 6.5. I know in the standard rails way, you call number_to_currency(price) to get the formatted value in the Views. I need to programmatically call the price field as well formatted string, i.e. $6.50 a few places that are not directly part of the View. Also, my needs are simple (no currency conversion etc), I prefer to have the price formatted universally in the model without repeated calling number_to_currency in views. Is there a good way I can modify my getter for price such that it always returns two decimal place with a dollar sign, i.e. $6.50 when it's called? Thanks in advance.

• ASP.NET MVC 2: Deserialize SPROC Response

  - by dcolumbus

  I need to ask a general question. I don't have the code in front of me because I'm writing this on my iPhone. I have a Class that represents a certain XML schema. I have a SPROC that returns this XML. What I need to do is deserialize the XML to this Class. XML: <xml> <person> <firstName>Bob</firstName> <lastName>Robby</lastName> </person> </xml> I need to deserialize this XML into the custom Person Class so I can loop through this Model and spit it out in the View. I'm sure there's some kind of casting involved, I just don't know how to do it.

• What does setting the GL color before doing a texture mapping operation do?

  - by quixoto

  I am looking at some sample code in a book that creates a jittered antialiasing effect by repeatedly rendering a scene (at different offsets) onto a offscreen texture, then using that texture to repeatedly draw a quad in the main view with some blend stuff set up. To accumulate the color "correctly", the code is setting the color like so: glColor4f(f, f, f, 1); where f is 1.0/number_of_samples, and then binding the offscreen texture and rendering it. Since textures come with their own color and alpha data, what is the effect (mathematically and intuitively) that setting the overall "color" in advance achieves? Thanks.

• Loop a UIScrollviw with ViewControllers

  - by Jim

  Hi I'm trying to create a UIScrollView with loop that contains a collection of ViewControllers. The answer to this question here shows the code that is the basis for what I'm trying to do. It uses images instead of viewControllers. I've managed to get the all the viewControllers loaded (4) and displaying but the first view which is a duplicate of the last viewController is blank. I've tried creating a copy of this viewController and adding it to the array but this messes up the transition / count. Any suggestions?

• Adding global blank option to DroDownList in MVC

  - by Diegos Grace

  Is there a way of using a templated helper in mvc so that each and every select list in my project has a custom default 'Choose an option' with null value etc. The posts I have seen seem a little complex, is it possible to have a DropDownList.ascx file in shared view folder with something like this: <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<IEnumerable<SelectListItem>>" %> <%= Html.DropDownList(selectlist name, selectlist value, "Choose an option")%> And then having a UIHint("DropDownList") for each dropdownlist in the ViewModel? Some guidance on syntax of parameters would be much appreciated, where name and value of the viewmodel dropdownlist plus the 'Choose an option' string are passed. Or is this all wishful thinking?

• action method is not called in JSF

  - by gurupriyan.e

  This is my Phase Listener public class AdminPhaseListener implements PhaseListener { private static final long serialVersionUID = -1161541721597667238L; public void afterPhase(PhaseEvent e) { System.out.println("after Phase " + e.getPhaseId()); } public void beforePhase(PhaseEvent e) { System.out.println("before Phase " + e.getPhaseId()); if(e.getPhaseId()== PhaseId.RESTORE_VIEW) { } } public PhaseId getPhaseId() { return PhaseId.ANY_PHASE; }} On click of a Command Button in my page, i call an action method and do some processing but the action method is not called at all, but in the server log , i could see the messages printed by my PhaseListener for all the Phases. If my view was not changed, It would have stopped after the RESTORE_VIEW Phase right? any thoughts?

• FCKEditor breaking HTML forms

  - by Mike

  I'm in the process of reproducing some standalone HTML forms as pages in a CMS that uses FCKEditor by simply copying and pasting the relevant code into the editor. But when I save and view the page, the HTML has been changed and the tag has been moved up to just below the open tag -- and not at the bottom of the form. This obviously renders all of the fields in the form, including the submit button, useless. Is there a way to tell FCKEditor that I know what I'm doing and I don't need it to validate the HTML output? Unfortunately this is a hosted CMS service (actually part of an email blast tool) so making changes to the configuration will mean I need to go through the company's support system, which is fine -- but they haven't been able to solve it for me yet, so I'm hoping to get the answers for them. Thanks!

• Correct way to give users access to additional schemas in Oracle

  - by Jacob

  I have two users Bob and Alice in Oracle, both created by running the following commands as sysdba from sqlplus: create user $blah identified by $password; grant resource, connect, create view to $blah; I want Bob to have complete access to Alice's schema (that is, all tables), but I'm not sure what grant to run, and whether to run it as sysdba or as Alice. Happy to hear about any good pointers to reference material as well -- don't seem to be able to get a good answer to this from either the Internet or "Oracle Database 10g The Complete Reference", which is sitting on my desk.

• Show all objects on canvas in window

  - by Number8

  Hello -- We have a canvas with a large number of objects. The user can pan and zoom the view of the canvas. I am trying to figure out how to implement "show entire canvas" -- that is, zoom and center the canvas in the window to show all objects. We know the max and min X and Y coordinates. I am looking at our current zoom and pan implementations to try to figure out if there is a way to use them. Any suggestions on how to do this would be appreciated... Thanks.

• AdMob ad is showing in iOS simulator, but not on iDevice

  - by Ben Toscano

  As the heading states, I can get my AdMob Ad to show in the iOS 5.1 and 6.0 simulator just fine, however, when running my application on my iOS 5.1.1 or 6.0 devices, there is just a blank space where the ad should be served. The code in my .m file is as follows: bannerView_ = [[GADBannerView alloc] initWithFrame:CGRectMake(0.0, 411.0 - GAD_SIZE_320x50.height, GAD_SIZE_320x50.width, GAD_SIZE_320x50.height)]; bannerView_.adUnitID = @"**myID**"; bannerView_.rootViewController = self; [self.view addSubview:bannerView_]; [bannerView_ loadRequest:[GADRequest request]]; //GADRequest *r = [[GADRequest alloc] init]; //r.testing = YES; //[bannerView_ loadRequest:r]; Furthermore, if I initiate testing of ads (see commented-out section), the test ad shows on both the simulator AND my iDevices, which is baffling me! What am I missing? Thanks for your help.

• Drag and drop + custom drawing in Android

  - by Rich

  I am working on something that needed custom drag-and-drop functionality, so I have been subclassing View, doing a bunch of math in response to touch events, and then rendering everything manually through code on the canvas in onDraw. Now, the more functionality I add, the more the code is growing out of control and I find myself writing a ton more code than I would expect to write in a high level environment like Android. Is this how it's done, or am I missing something? If I'm not doing anything fancy in the UI, the framework handles the majority of my interactions. Built-in controls handle the touches and drags, and my code is pretty much limited to business logic and data. Is there a way to leverage the power of some of the UI controls and things like animations while also doing some of it manually in the onDraw canvas? Is there an accepted standard of when to use one or the other (if indeed the two approaches can be mixed)?
