• Update Message on ASP.NET ModelPopupExtender

  - by John

  Hi, I have a form in a MS AJAX ModalPopup Extender, which is in a UpdatePanel (for async loading). Everything works as expected. There is one thing that I am trying to do but not sure how to do it. On form submission, there is server side validation on top of client side validation. My question is: what is the best way to display validation error messages if any? It would be ideal if the messages could be written to the popup asynchronously so that the popup is still there. If this is not possible, I am thinking of displaying the messages using the JavaScript alert box. Any insight and suggestions are greatly appreciated. John

• How can I access the value of a checkbox without a postback?

  - by Starwfanatic

  I have a radgrid controlling access to an application for users. There are two columns, a 'name' column and a checkbox 'access' column representing their current access permission. the checkboxes are populated from a database. I would like the to change the checkboxes to grant or deny access to the users I specify. Since there are alot of users I would like to make multiple changes and use a submit button to write the changes to the database. I do not want to postback with each checkbox change and wait for the page to "blink". My problem is that with the checkbox postback disabled, when I click submit, the value of the checkboxes are not registering the changes I make. I need a way to access the current client-side state of the checkbox or some workaround to accomplish this. Thanks in advance!

• Design issue with ATG CommercePipelineManager

  - by user1339772

  The definition of runProcess() method in PipelineManager is public PipelineResult runProcess(String pChainId, Object pParam) throws RunProcessException This gives me an impression that ANY object can be passed as the second param. However, ATG OOTB has PipelineManager component referring to CommercePipelineManager class which overrides the runProcess() method and downcast pParam to map and adds siteId to it. Basically, this enforces the client code to send only Map. Thus, if one needs to create a new pipeline chain, has to use map as data structure to pass on the data. Offcourse, one can always get around this by creating a new PipelineManager component, but I was just wondering the thought behind explicitly using map in CommercePipelineManager

• Easiest way to convert json data into objects with methods attached?

  - by John Mee

  What's the quickest and easiest way to convert my json, containing the data of the objects, into actual objects with methods attached? By way of example, I get data for a fruitbowl with an array of fruit objects which in turn contain an array of seeds thus: {"fruitbowl": [{ "name": "apple", "color": "red", "seeds": [] },{ "name": "orange", "color": "orange", "seeds": [ {"size":"small","density":"hard"}, {"size":"small","density":"soft"} ]} } That's all nice and good but down on the client we do stuff with this fruit, like eat it and plant trees... var fruitbowl = [] function Fruit(name, color, seeds){ this.name = name this.color = color this.seeds = seeds this.eat = function(){ // munch munch } } function Seed(size, density){ this.size = size this.density = density this.plant = function(){ // grow grow } } My ajax's success routine currently is currently looping over the thing and constructing each object in turn and it doesn't handle the seeds yet, because before I go looping over seed constructors I'm thinking Is there not a better way? success: function(data){ fruitbowl.length = 0 $.each(data.fruitbowl, function(i, f){ fruitbowl.push(new Fruit(f.name, f.color, f.seeds)) }) I haven't explored looping over the objects as they are and attaching all the methods. Would that work?

• How can I search for an email using the zend framework?

  - by Ali

  Hi guys I need to build a functionality that involves searching through emails in an inbox for emails whose subjects match a certain user inputted keyword. SInce I'm using the zend framework I would like a solution that uses the zend framework libraries. Aside this I have noticed that the zend libraries are a bit limited with respect to my requirements for email handling. Is there any open library available in php which can be used for handling emails - when I mean handling emails I mean like: Ease to mark and flag emails Moving of emails from folder to folder. Parsing emails searching through emails SOrting emails etc - the stuff you would require if you wished to build a web client. EDIT ========= I'm looking for a generic solution here. The emails are in a regular email inbox on an IMAP server. I need a way to be able to read through and search for emails in the inbox using any specialized library to make it easier.

• Is adding a bit mask to all tables in a database useful?

  - by Tom

  A colleague is adding a bit mask to all our database tables. In theory this is so we can track certain properties of each row across the entire system. For example... Is the row shipped with the system or added by the client once they've started using the system Has the row been deleted from the table (soft deletes) Is the row a default value within a set of rows Is this a good idea? Are there other uses where this approach would be beneficial? My preference is these properties are obviously important, and having a dedicated column for each property is justified to make what is happening clearer to fellow developers.

• Ajax: Load XML from different domain?

  - by John Isaacks

  I have signed up(paid) for Google site search. They have me a url of a sort of web service where I can send a query to it, it searches my site, and it returns XML of the search results. Well I am trying to load this XML via Ajax from a page on my site but I cannot. I can load from any of my pages on my domain so I am assuming it is because of the XML being on Google's domain. So there has got to be a way to load it though, I don't think they would have given me the URL if I couldn't do anything with it lol. Does anyone know how to do this? Thanks! UPDATE: this is what the page says on google that gave me the XML: How to get XML You can get XML results for your search engine by replacing query+terms with your search query in this URL: http://www.google.com/cse?cx=MY_UNIQUE_KEY&client=google-csbe&output=xml_no_dtd&q=query+terms Where MY_UNIQUE_KEY = my unique key.

• Where do current (not HTML5) browsers stand on clipboard support for non-text data?

  - by John

  I don't really know where the line is between the browser itself and HTML/JS here. But let's say I want to write a web-app where I can copy a chunk of data from MSPaint (select, CTRL+c) and paste it into a web-page in some way... ultimately the point is the data goes to the server without me having to save it as a file first. Where are the problems here - browsers or client-side technologies? For instance if JS can't do it, could Flex/Silverlight? Advice on future technology welcome, but doesn't really answer the question - where are we right now with IE/FF/Chrome and JS/Flex/SL?

• Unit Testing User Interface. What is an effective way ?

  - by pierocampanelli

  I have an accounting & payroll client/server application where there are several input form with complex data validation rules. I am finding an effective way to perform unit testing of user interface. For complex validation rules I mean: "Disable button X if I Insert a value in textfield Y" "Enable a combobox if I insert a value in a textfield" ...... ...... Most promising pattern i have found is suggested by M. Fowler (http://martinfowler.com/eaaDev/ModelViewPresenter.html). Have you any experience about Unit Testing of User Interface? As technology stack I am using: .NET 3.5 & Windows Forms Widget Library.

• Overriding a method in statically created objects

  - by I82Much

  All, Due to a bug in a library I'm using, I need to override the dispose() method on all objects extending a certain class and make it a NO-OP. I know that if I'm making new instances of the classes directly, this is easy to do: layerManager = new LayerManagerLayer(wwd) { @Override public void dispose() {} }; The problem is that a lot of the object instances I get are not directly constructed by my client code, but instead are created via static library method calls. // Here I want to override the dispose method, but I cannot. Layer l = ShapefileLoader.makeShapefileLayer(this.getClass().getResource("polylines10.shp")); Is there a way I can inject my dispose method into that statically created object without modifying the original sourcecode?

• PowerPoint.Application not raising events in C#

  - by AdmSteck

  I have a simple application written in C# and .Net 2.0 that displays several PowerPoint 2003 files in a loop. (It is going to be used for a information board in our cafeteria) The application works fine on my development machine but when I deploy it to another machine the events I have registered for SlideShowNextSlide and PresentationClose are never fired. I have tried registering the events with this method. private void InitPPT() { app.SlideShowNextSlide += new Microsoft.Office.Interop.PowerPoint.EApplication_SlideShowNextSlideEventHandler(app_SlideShowNextSlide); app.PresentationClose += new Microsoft.Office.Interop.PowerPoint.EApplication_PresentationCloseEventHandler(app_PresentationClose); app.SlideShowEnd += new Microsoft.Office.Interop.PowerPoint.EApplication_SlideShowEndEventHandler(app_PresentationClose); } And with this method that I found here: private void InitPPT() { IConnectionPointContainer oConnPointContainer = (IConnectionPointContainer)app; Guid guid = typeof(Microsoft.Office.Interop.PowerPoint.EApplication).GUID; oConnPointContainer.FindConnectionPoint(ref guid, out m_oConnectionPoint); m_oConnectionPoint.Advise(this, out m_Cookie); } Do I need to register some dll's on the client machine or am I missing something.

• Is there any framework for Windows Forms, DB driven application development/prototyping?

  - by dolzenko

  I'm writing simple database driven application, 80% of functionality is CRUD operations on about 15 tables. Coming from web development background I figured I can cover almost all of these CRUD cases with Rails scaffolding or say Django admins. So I started to look around for Rails/Django-like framework but for Windows Forms applications (ofcourse I understand that "rich client" application development significantly differs from a web development and I'm not expecting anything really similar). I was surprised that except for a variety of ORMs (let's call it Model-layer) it seems like I'm left with little choice when it comes to View-Controller layer. Maybe I'm missing something? PS. I evaluated Visual Studio DataSet Designer, but it seems to work only for the most simple cases, and requires additional code for any slightly nontrivial task. (added) so far I've found: TrueView for .NET (thanks to Vijay Patel) NConstruct

• OracleDataAdapter returns no rows, but the query string works in SQLDeveloper

  - by belzebu

  visual studion 2008 oracle db 11.1.0.7 oracle client for .NET I have a relatively simple query, that selects the rows from across multiple tables (up to 4) using joins. OracleDataAdapter returns no rows for the only dataset's table, but if I copy and paste that query in SQLDeveloper then I get the desired results. I can get the data from other tables using the adapter with no problem, but it seems like it struggles with the bit longer selection query (string length is ~ 300 (not that much at all)) Connection string for the connection is 100% correct. Any ideas? thank you...

• Webservice and ORM Framework?

  - by Sebastian

  Does anybody know a good web framework that includes an ORM mapper and allows straight forward implementation of web services? I'm looking for a framework written in PHP or C++. I'm looking for the following features (not all of them required, some will do nicely) data definition in one place used by database and web service WSDL generation XML output/JSON output boilerplate code generation So what I would like is a framework that let's me specify the objects, the web service functions on those objects and then generate everything that is required leaving me to fill the business logic (connecting the database to the web service). Anything like that out there? Background information for why I need this: I'm looking into creating a web project: the client is a rich web application that fetches all its data using AJAX. It will be completely custom made using only a low level javascript library. The server back end is supposed to serve static content and javascript (basically the rich web application) and to provide a RESTful web service API (which I would like to implement using aforementioned framework).

• How do I manage report paging in HTML?

  - by ProfK

  I have a small, custom crafted HTML report, not using any reporting engine, for various reasons. The client's layout is quite handy, as each report section fits on its own page, so I have one div for each page, with a CSS class of .page, setting A4 dimensions with margin, and a header image. Each 'page' also has a small header table just under the header image, and a section heading label. Now, some sections threaten to overflow their page, and I'm looking at ways to handle this. One clumsy approach is to include a second page for those sections that might overflow, and delete these pages before rendering if they are empty. If I do this, how can I 'tell' content on one page to overflow into the next page? The report is finished and a once off effort, so I'm not keen to convert it into a SSRS or Telerik report just to achieve this paging.

• Connect to Oracle database on a different server from PHP

  - by macha

  Hello I have a database engine sitting on a remote server, while my webserver is present locally. I have worked pretty much with client-server architecture, where the server has both the webserver and the database engine. Now I need to connect to an Oracle database which is situated on a different server. Can anybody give me any suggestions?? I believe ODBC_CONNECT might not work. Do I use OCI8 drivers?? How would I connect to my database server. Also I would have a very high number of database calls going back and forth, so is it good to go with persistent connection or do I still use individual database calls?

• Is there such a thing as a converter from php to html?

  - by 0plus1

  Don't think that I'm mad, I understand how php works! That being said. I develop personal website and I usually take advantage of php to avoid repetion during the development phase nothing truly dynamic, only includes for the menus, a couple of foreach and the likes. When the development phase ends I need to give the website in html files to the client. Is there a tool (crawler?) that can do this for me instead of visiting each page and saving the interpreted html?

• Where to draw the line between efficiency and practicality

  - by dclowd9901

  I understand very well the need for websites' front ends to be coded and compressed as much as possible, however, I feel like I have more lax standards than others when it comes to practical applications. For instance, while I understand why some would, I don't see anything wrong with putting selectors in the <html> or <body> tags on a website with an expected small visitation rate. I would only do this for a cheap website for a small client, because I can't really justify the cost of time otherwise. So, that said, do you think it's okay to draw a line? Where do you draw yours?

• File listing application on Windows : what language ?

  - by Studer

  I need to create a simple application/script able to list the hierarchy of a folder containing subfolders and files (mostly PDF), so that a user can browse easily these files and maybe have a quick preview of them. The files are all on an internal file server, so the dynamic aspects should all be client-sided. My goal (and what my boss want) is to provide some sort of an HTML page listing, to have something like this. The only problem I have now is that I cannot install anything on computers, so I cannot use PHP, Python, ... This application will only runs on Windows in Internet Explorer. What are the different possibilities I have ? I don't know if I can do this but I was thinking of using HTML + Flex. Thanks for helping.
