• Multiple skins in ASP.NET MVC using StringTemplate

  - by Jamie

  I am considering the StringTemplate view engine for my ASP.NET MVC application. This application will be built with one skin, but I then expect many more, often very similar skins to be developed for it. This is primiarly the reason for my choice of StringTemplate as the view engine, as there will be zero logic in the views. In my head, I envisaged having each skin in a directory under the 'Views' directory in the folder structure, then maintaining a data structure which maps hostnames to skin directories. An obvious disadvantage of this approach is that I will have to explicitly specify my view files - an alternative might be to hack the implementation of the View() method to change the /views/controller/action standard path and insert an extra layer. Is anyone aware of any examples of implementations along these lines using ASP.NET MVC and StringTemplate at present? Can anyone forsee any potential problems with my approach? Thanks in advance.

• RPG Game loop and class structure (cocos2D for iPhone)

  - by mac_55

  I'm looking to make an RPG with Cocos2D on the iPhone. I've done a fair bit of research, and I really like the model Cocos2D uses for scenes. I can instantiate a scene, set up my characters etc. and it all works really nicely... what I have problems with is structuring a game loop and separating the code from the scenes. For example, where do I put my code that will maintain the state of the game across multiple scenes? and do I put the code for events that get fired in a scene in that scene's class? or do I have some other class that separates the init code from the logic? Also, I've read a lot of tutorials that mention changing scenes, but I've read none that talk about updating a scene - taking input from the user and updating the display based on that. Does that happen in the scene object, or in a separate display engine type class. Thanks in advance!

• ExtAsp or Coolite - ASP.NET wrappers around ExtJs

  - by Jon

  Hi, We are a small Microsoft shop looking into ExtJs and like the rapid building of complex and structured UIs that can be achieved with the toolkit. However we have been experimenting with ExtAsp.NET (CodePlex) which is an opensource layer of ASP.NET code which wraps around the ExtJs framework. We have also noticed the Coolite framework which looks good too and does the same thing. We have 2 options, either we purchase the ExtJs license which will be required if we use ExtAsp, or we purchase the Coolite kit which includes the ExtJs license. It looks like Coolite is actually it little cheaper than the ExtJs for some reason?? However, is it a little more risky as regards upgrade path if the Coolite framework becomes unsupported, whereas ExtAsp as an open source solution will have community backing? Just looking to make the right step.

• Is learning the Caché database hard coming from relational databases and object oriented programming

  - by Edelcom

  I am currently running the local version of Caché on my system in order to determine if I can (and will) take on a new possible project. The current project uses Delphi 7 as a front end calling a Caché dll where the business logic is stored in the database. I have a background of Sqlserver and Firebird (and before Access and Paradox) as databases. I use Delphi 7 for 95% of my Windows development, so I know about object programming. I would like to recieve opinions from persons having used Caché and either SqlServer, Firebird or Oracle and having developed in Delphi (or C++ or C# - an object oriented language). I have read the pro's and con's from other questions, but I am not asking for this, I need input from Caché developers. Thanks in advance.

• Grails GIS Application

  - by Steve Wall

  Hello, I'm working on an internal IT application monitoring outages for a network with a national footprint in the US. I'm considering overlaying outages by region on a map. Showing outage areas in red for example. The user clicks on the outage area displaying drill down information. The technology stack includes Grails/JBoss/Linux. Are there frameworks that provide the mapping/GIS layer of the display on which I could overly my domain specific information? I've looked into the Google Map API, but am unable to leverage it as this operates behind a firewall. Any ideas? Thanks in advance, Steve

• Too late to become a programmer?

  - by Tomas

  Hi, Working in IT for 5 years, I focused on system integration - testing, performance tests and analysis, automation etc. Altough I am working for one of the biggest IT companies, I have the possibility to come up with my own ideas and realize them - for example I have written C# (with SQL backend) bugtracker application with management elements...and I really liked it. I am very creative person but being 25 y/o, I am wondering whether it is too late. I understand the logic of programming but as I was never very good in math I assume I have no chance to become professional programmer in this age. What do you think? Thanks

• Embedded Linux or eCos ?

  - by mawg

  One way to look at it - embedded Linux starts with desktop Linux & ditches the parts not needed for embedded systems (is this actually true?), whereas eCos is designed from the ground up for embedded systems. Now, assume an ARM processor, probably ARM 7 - does performance make a difference? Actually, we talking a very low load system, max 500 transactions a day. Any advantages of one over the other (or FreeRTOS, etc)? Stability, maturity, performance, development tools, anything else? All that I can think of is that if I am certain that I will never port to another o/s, then if I go with embedded Linux, I don't need an o/s abstraction layer to allow me to do unit testing on host (desktop Linux box). Any thoughts or comments? Thanks.

• Email attachment parsing via mime4j

  - by Ashish

  Hi, I am using a small java smtp library (http://code.google.com/p/subethasmtp/), by this I need to parse the incoming emails in separate components viz body, attachments etc. I am trying to use mime4j , but the documentation suggests that mime4j can only give event notification or token notification and nothing else. For stripping out body and attachments etc I had to use my own custom logic inside the event handlers. Is my observation correct? If yes then how can I use mime4j to use for my requirement. Please suggest. I badly need an approach that takes in the smtp data stream and returns me with an array of attachment references or streams in fully parsed out form in java. Please help. Thanks in advance Ashish Sharma

• Fastest way to access VB6 String in C#

  - by Simon Woods

  Hi I am using COMInterop. I have a call in VB6 which returns a string of roughly 13000 chars. If I execute the call in pure VB6 it takes about 800ms to execute. If I execute it via c# and COMInterop it takes about 8 seconds. I'm assuming the delay is caused by marshalling. If I am correct about marshalling, I'd be grateful if someone could suggest the fastest way I can get this into C#. e.g. Would it be better to a) expose it as a byte array b) provide a byref string param into the VB6 layer I would appreciate some sample code as well. I tried the Marshal.PtrToStringAuto(Marshal.ReadIntPtr(myCOMObject.GetString, 0) to no avail Many thx S

• Entity Framework and consuming a WCF service

  - by nakori

  I'm getting data where the database is hidden behind a WCF service. Is it possible to use Entity Framework in a scenario where I have custom objects coming from a web service? (No access to the external database, and no current plans for insert/update/delete logic) Starting with an empty EF model and adding an entity I get this error on compile: No mapping specified for instances of the EntitySet and AssociationSet in the EntityContainer .. Is it possible to make an entity this way, and fill it with data received from an object? (In this case a WCF, but could also be a predefined model class/xml data) If the web service retured a Customer object I could do something like this with a dataset: Make an unbound table and do a loop through the customer properties adding them to a temp row, add it with tbl_Customer.Addtbl_CustomerRow(customerRow) to get my view filled. thanks, nakori

• Hows does Seam injection work in Ejb3

  - by kazanaki

  Hello We are using Seam 2.2.0 Java 1.6.14 Weblogic 10.3.1.0 (named 11g Doh!) I have looked at Seam reference Seam in action These web pages However I still do not understand how to inject an EJB3 bean into a JSF backing bean. It seems to me that I have to (correct me if I am wrong) Annotate with @Name my backing bean Annotate with @Name my EJB3 bean Use the @In annotation in the backing bean Put an empty seam.properties file in the WAR that contains the backing bean Put an empty seam.properties file in the JAR that contains the EJB Set up a Seam interceptor in ejb-jar.xml of the EJB Don't I need to setup some JNDI URL somewhere? How exactly does Seam will find the EJB? The interceptor is enough? Also this means that I have to add a seam dependency in my EJB archive (because of the @Name annotation). So the web layer (Seam) "spills" into my business logic (EJB). Is this the recommended approach? Am I missing something here?

• Infragistics Webgrid (Datagrid) dynamic adjusting columns

  - by mattgcon

  I want to explain this as best as I can. I have a Webgrid with a certain amount of columns. What I want is for the columns to adjust to the size of the largest string within each column, where the total of all width of columns does not exceed the width of the webgrid. At the same time however if the width of all columns is less than the width of the webgrid I want each column to adjust proportionately so that the total of columns widths equal the width of the webgrid. Can anyone help me with this logic?

• Handling redirected URL within Flex app?

  - by fortpointuiguy

  We have a Flex client and a server that is using the Spring/Blazeds project. After the user logs in and is authenticated, the spring security layer sends a redirect to a new URL which is where our main application is located. However, within the flex client, I'm currently using HTTPService for the initial request and I get the redirected page sent back to me in its entirety. How can I just get the URL so that I can use navigatetourl to get where the app to go where it needs to? Any help would greatly be appreciated. Thanks!

• Rack rSpec Controller Tests with Rack Middleware issue

  - by Roman Gonzalez

  Howdy, I'm having big trouble testing with rSpec's controller API. Right now I'm using a middleware authentication solution (Warden), and when I run the specs, the proxy added by the middleware is not there, and all the authentication tests are throwing NilPointerExceptions all over the place. It seems rSpec is not adding the middleware to the final app on purpose, and I would like to know if there is a way to monkey patch rSpec in order to make that go. I already tested the whole thing with cucumber, however this is a refactoring of an old authentication version and there is several Controller tests that depend on authentication logic in order to work. Thanks in advance.

• Capturing network traffic in ruby - pcap related issues

  - by Acidburn2k

  What I need is to write very simple application, which would listen to network traffic, filter out some packets based on various layer 4/5 information and then dump those information into database. I am quite confused on which pcap gem/plugin should I use. The basic pcap implemention seem to be a bit outdated (no changes since 2001) and doesn't work properly. I also tried pcaprub, but I am not quite sure how to get around with this library. It seem to capture raw packets without te ability to actualy get any data out of the pcap dump. Do you have any advices on how can I realize this simple task? Thanks in advance. :-)

• ASP.NET MVC Ajax Form: Is enctype correct? Why doesn't file get uploaded?

  - by Fabio Milheiro

  In the case that the user doesn't have Javascript activated, in order to draw a form, I begin this way: <% using (Html.BeginForm("Create", "Language", FormMethod.Post, new {enctype="multipart/form-data"})) { %> If the user has Javascript activated, the following code is used: <% using (Ajax.BeginForm("Create", "Language", new AjaxOptions { UpdateTargetId = "CommonArea" }, new { enctype = "multipart/form-data" })) { %> The problem is this: In the first case, I can get the file uploaded using the following instruction in the business layer: // Get the uploaded file HttpPostedFile Flag = HttpContext.Current.Request.Files["Flag"]; In the second case, this instruction doesn't work. How do I know upload that file using the Ajax.BeginForm? Is the code right? Can anyone more experience advise about using jQuery plug-in to upload file before the form submission? Thank you

• How to Prevent SelectionChange a Silverlight DataGrid

  - by Matt Eland

  I'm using a Silverlight 3 DataGrid control and have set the SelectionMode to Extended. The DataGrid takes care of managing the extended selection for me in an almost perfect manner out of the box, but a key piece of the logic is interfering with me. I have a cell that can function as a drag and drop thumb and initiate a drag operation but users want to do a series of shift or control clicks to set a selection followed by a click and drag on one of the selected rows to initiate the drag. The problem is that the click and drag at the end of this series causes the selection to be set to only the row that was clicked. I've poked around for ways of conditionally preventing the DataGrid from changing selection, but can't seem to find anything that works. Does anyone have any ideas for preventing selection from changing?

• Sharepoint Web Part OnPreRender PostBack Dynamic TextBoxes Not Accessible In Button Handler

  - by Matt

  I have a custom webpart which extends System.Web.UI.WebControls.WebPart and implements an EditorPart. I have all the static controls being added in the overridden CreateChildControls method as I know this makes them persistent across PostBacks. However, I have some TextBoxes being added in the overridden OnPreRender method because the actual TextBoxes that I add depend upon the data returned from a Web Service which I am calling in OnPreRender. The Web Service has to be called in OnPreRender because I need some of the Property values that are set in the EditorPart. If I build this logic into the CreateChildControls method, obviously the data is not available on first PostBack after an edit is applied because the PostBack events are restored after CreateChildControls. This means the page has to be posted twice before the data is refreshed and that is just cludgy. How can make these TextBoxes along with their entered text values persistent across PostBacks so that I can access them in the button handler? Thanks for any help, Matt

• Convert byte array from Oracle RAW to System.Guid?

  - by Cory McCarty

  My app interacts with both Oracle and SQL Server databases using a custom data access layer written in ADO.NET using DataReaders. Right now I'm having a problem with the conversion between GUIDs (which we use for primary keys) and the Oracle RAW datatype. Inserts into oracle are fine (I just use the ToByteArray() method on System.Guid). The problem is converting back to System.Guid when I load records from the database. Currently, I'm using the byte array I get from ADO.NET to pass into the constructor for System.Guid. This appears to be working, but the Guids that appear in the database do not correspond to the Guids I'm generating in this manner. I can't change the database schema or the query (since it's reused for SQL Server). I need code to convert the byte array from Oracle into the correct Guid.

• Hibernate Criteria: Add restrictions to Criteria and DetachedCriteria

  - by Gilean

  Currently our queries add a variety of Restrictions to ensure the results are considered active or live. These Restrictions are used in several places/queries so a method was setup similar to public Criteria addStandardCriteria(Criteria criteria, ...) { // Add restrictions, create aliases based on parameters // and other non-trivial logic criteria.add(...); return criteria; } This has worked fine so far, but now this standard criteria needs to be added to a subquery using DetachedCriteria. Is there a way to modify this method to accept Criteria or DetachedCriteria or a Better way to add restrictions?

• Using the Specification Pattern

  - by Kane

  Like any design pattern the Specification Pattern is a great concept but susceptible to overuse by an eager architect/developer. I am about to commence development on a new application (.NET & C#) and really like the concept of the Specification Pattern and am keen to make full use of it. However before I go in all guns blazing I would be really interested in knowing if anyone could share the pain points that experienced when use the Specification Pattern in developing an application. Ideally I'm looking to see if others have had issues in Writing unit tests against the specification pattern Deciding which layer the specifications should live in (Repository, Service, Domain, etc) Using it everywhere when a simple if statement would have done the job etc? Thanks in advance

• Problem building dotnetnuke blog module

  - by GeminiDNK

  I have dnn 5.2 running on my machine, and installed the blog module, the blog module is also reflected in the development environment i have. But i want to find out, how do i actually develope, or build the blog from source, so i can actually output the .dll file, instead of just running it. If i import the Blog project file from the folder, it will give me a host of error like .resx file not found and so on. Does any dotnetnuke expert out there know about this?And have encountered the problem before? If not, how do you actually make the module work so u can make changes to the module. Im talking about core logic change, like adding functions, not just skin or UI changes.

• How to get MAX value of a version-number (varchar) column in T-SQL

  - by Ogre Psalm33

  I have a table defined like this: Column: Version Message Type: varchar(20) varchar(100) ---------------------------------- Row 1: 2.2.6 Message 1 Row 2: 2.2.7 Message 2 Row 3: 2.2.12 Message 3 Row 4: 2.3.9 Message 4 Row 5: 2.3.15 Message 5 I want to write a T-Sql query that will get message for the MAX version number, where the "Version" column represents a software version number. I.e., 2.2.12 is greater than 2.2.7, and 2.3.15 is greater than 2.3.9, etc. Unfortunately, I can't think of an easy way to do that without using CHARINDEX or some complicated other split-like logic. Running this query: SELECT MAX(Version) FROM my_table will yield the erroneous result: 2.3.9 When it should really be 2.3.15. Any bright ideas that don't get too complex?
