• CakePHP with AJAX loaded pages

  - by Jacques Wolfghang

  Hi there. I am trying to create a website in which all interaction takes place on a single page which has its main content filled via AJAX. The site is effectively a template with a central interaction area. Users can click links which results in an AJAX request to fetch a new page to display in the interaction area. In this way, the page never refreshes, instead it has its content fetched and displayed via AJAX. I have found that the CakePHP framework has many useful features that could work with this project, however, I do not no if the Cake's MVC architecture would work with my single page architecture. So, what I really want to know is if I can use CakePHP features and functions on a website of this type, and also if anyone could give me any helpful tips on how I would go about implementing it. I am sorry if this is rambling or vague, english is not my mother tongue so I have trouble expressing what I have to say clearly. Thank you for your time.

• Why don't Direct2D and DirectWrite use traditional COM objects?

  - by David Brown

  I'm toying with a little 2D game engine in C# and decided to use Direct2D and DirectWrite for rendering. I know there's the Windows API Code Pack and SlimDX, but I'd really like to dig in and write an interface from scratch. I'm trying to do it without Managed C++, but Direct2D and DirectWrite don't appear to use traditional COM objects. They define interfaces that derive from IUnknown, but there appears to be no way to actually use them from C# with COM interop. There are IIDs in d2d1.h, but no CLSID. Of course, I'm really new to COM interop, so perhaps I'm just missing something. Can someone shed some light on this situation?

• HTTP Error 500.19 - Internal Server Error for silverlight application

  - by KentZhou

  Use VS2010 silverlight business application template to createa defaut solution. Change authentication to Windows in Web.config and the code in app.xaml.cs to use windows authentication. Nothing else changed. Then run this app from vs2010 built-in web server, it is fine, I can see the login user info from windws(from a AD domain account) display on the top-right of the screen, like DomainName\userName. Then deploy this web app to IIS on windows 7(same computer) and access this app again, I got following error: HTTP Error 500.19 - Internal Server Error The requested page cannot be accessed because the related configuration data for the page is invalid.

• Get the currently saved object in a view in Django

  - by mridang

  Hi, I has a Django view which is accessed through an AJAX call. It's a pretty simple one — all it does is simply pass the request to a form object and save the data. Here's a snippet from my view: form = AddSiteForm(request.user, request.POST) if form.is_valid(): obj = form.save(commit=False) obj.user = request.user obj.save() data['status'] = 'success' data['html'] = render_to_string('site.html', locals(), context_instance=RequestContext(request)) return HttpResponse(simplejson.dumps(data), mimetype='application/json') How do I get the currently saved object (including the internally generated id column) and pass it to the template? Any help guys? Mridang

• Subsonic 3 fails to identify Stored Procedure Output Parameter

  - by CmdrTallen

  Hi using Subsonic 3.0.0.3 it appears there is some issue with Subsonic identifying Stored Procedure paramters as output parameters. In the StoredProcedures.cs class I find my stored procedure definition but the last parameter is defined incorrectly as a 'AddParameter'. sp.Command.AddParameter("HasPermission",HasPermission,DbType.Boolean); When I sp.Execute() and attempt to read the value of the sp.Command.OutputValues[0] the value is null. If the definition is edited to be like this; sp.Command.AddOutputParameter("HasPermission", DbType.Boolean); Then the value is returned and is correct value type I am not sure how I 'fix' this - as everytime I regen the SP class via the 'Run Custom Tool' the parameter definitions require editing. Should I edit a T4 template somehow? Please advise. EDIT: I forgot to mention I am using MS SQL 2008 (10.0.2531)

• Designing a data model in VS2010 and generating ORM code, application

  - by Kay Zed

  Simply put: I have a database design in my head and I now want to use Visual Studio 2010 to create a WPF application. Key is to use the VS2010 tools to take much as possible manual work out of my hands. -The database engine is SQLite -ORM probably through DBLINQ -Use of LINQ -The application can create new, empty database instances -Easily maintainable (changes in data model possible) Q- How do I start designing the database model (visually) in Visual Studio 2010? Should this be an xsd? Do I do this in a separate project? Q- Next, how can I make the most use of VS2010 code generation tools to generate a business layer? Q- I suppose the business layer will be added as a Data Source (in another project?) and from there it's a rather generic data binding solution? I tried finding clear examples of this but it's a jungle out there, the hunt for a solution is NOT converging to one clear method.... :_(

• Batch file script to remove special characters from filenames (Windows)

  - by njreed.myopenid.com

  I have a large set of files, some of which contain special characters in the filename (e.g. ä,ö,%, and others). I'd like a script file to iterate over these files and rename them removing the special characters. I don't really mind what it does, but it could replace them with underscores for example e.g. Störung%20.doc would be renamed to St_rung_20.doc In order of preference: A DOS batch file A Windows script file to run with cscript (vbs) A third party piece of software that can be run from the command-line (i.e. no user interaction required) Another language script file, for which I'd have to install an additional script engine Background: I'm trying to encrypt these file with GnuPG on Windows but it doesn't seem to handle special characters in filenames with the --encrypt-files option.

• Clicking DetailsView’s Update button doesn’t cause a postback

  - by AspOnMyNet

  If I define the following template inside DetailsView, then upon clicking an Update or Insert button, the page is posted back to the server: <EditItemTemplate> <asp:TextBox ID="txtDate" runat="server" Text='<%# Bind("Date") %>'></asp:TextBox> <asp:CompareValidator ID="valDateType" runat="server" ControlToValidate="txtDate" Type="Date" Operator="DataTypeCheck" Display="Dynamic" >*</asp:CompareValidator> </EditItemTemplate> But if I remove CompareValidator control from the above code, then for some reason clicking an Update or Insert button doesn’t cause a postback...instead nothing happens: <EditItemTemplate> <asp:TextBox ID="txtDate" runat="server" Text='<%# Bind("Date") %>'></asp:TextBox> </EditItemTemplate> Any idea why page doesn't get posted back? thanx

• How to return model state from child action handler in ASP.NET MVC

  - by Joe Future

  In my blog engine, I have one controller action that displays blog content, and in that view, I call Html.RenderAction(...) to render the "CreateComment" form. When a user posts a comment, the post is handled by the comment controller (not the blog controller). If the comment data is valid, I simply return a Redirect back to the blog page's URL. If the comment data is invalid (e.g. comment body is empty), I want to return the ViewData with the error information back to the blog controller and through the blog view to the CreateComment action/view so I can display which fields are bad. I have this working fine via AJAX when Javascript is enabled, but now I'm working on the case where Javascript might be disabled. If I return a RedirecToAction or Redirect from the comment controller, the model state information is lost. Any ideas?

• How should one import large amounts of data for FIT/Fitnesse tests?

  - by Lachlan

  We have a scheduling engine with large amounts of test data to test all the scenarios, so test automation is critical. We're currently hoping to use FIT/Fitnesse. However a single test has quite a large table of test data, so it doesn't fit very well into the mould of "two or three inputs, one or more outputs" that Fitnesse uses in its examples. Hopefully the other functionality of Fitnesse makes it worth using it. I hear that there is a way to initialize an application for a FIT test with an Excel spreadsheet - not the Spreadsheet to Fitness function, mind you - but I haven't been able to find it so far. Once the whole spreadsheet is loaded into the application, and the application does its thing, we plan to compare either a number of output rows, or perhaps just the last row, to see if the test passes. The application is currently pulling test data from a database for manual tests, but writing to a database, then initializing from it, is not preferred because of the performance impact. The application is written in C#.

• TableView as DetailView's subview with a UISplitViewController?

  - by Gerry

  I have a UISplitViewController, I used the iPad template to start. To change the type of view in the detailview area, I'm adding my view types as subviews to the DetailViewController's view. This works for UIViewController derived views, but not for UITableViewController view types?. Why would this be? My problem is rooted in the fact that the manufactured DetailView is the UISplitViewController's delegate. To get the correct popover behaviour, I'd like to keep it add buttons to its toolbar and then based on user selection open different details when master list selections are made. Thanks,

• Shopping Portal based on XML Data - XSLT or PHP?

  - by buggy1985

  For my bachelor thesis I want to implement a shopping (price comparison) portal prototype based on XML Data. The main requirement is to get a very clear and customizable HTML template, which should be hosted by the customer on his own webserver. I'm not very sure if XSLT meets this requirements, as it generates a lot of xsl-related code. It is not easy to understand for people with little HTML skills. I have some experience with the PHP templating engine Smarty. The syntax is much better, but I'm not sure if it's a good idea to parse the XML data with PHP, as it is very complex. Which language should I choose for a web application with high complexity? XSLT or PHP?

• sharp architecture question - no strongly typed views

  - by csetzkorn

  Hi, I am trying to get my head around the sharp architecture and used the visual studio template as described on the web: http://wiki.sharparchitecture.net/VSTemplatesAndCodeGen.ashx This is all cool. Unfortunately, I cannot add a strongly typed view as easily as I am used to ‘under’ asp.net mvc. What can I do to ‘enable’ this in VS 2008 Prof? I have also installed asp.net mvc 2.0 and would like to reflect this in my ‘vs studio sharp environment’. Any pointers would be very much appreciated. Many thanks in advance. Best wishes, Christian

• Erb with Sinatra in ruby

  - by JP

  So I have a webserver I've built using sinatra, the meat of which goes like this: set :variable,"value" get '/' do erb :index end And, of course, the template in views/index.erb which looks something like this: <html> <!-- etc --> <ul> <% my_array.each do |thing| %> <%="Something: #{thing}, variable from sinatra: #{settings.variable}"%> <% end %> </ul> </html> If you try running code like this you'll notice that you can't access sinatra's settings variable from inside erb templates. Any ideas how I can achieve this while keeping its simplicity? Thanks in advance!

• Use python decorators on class methods and subclass methods

  - by AlexH

  Goal: Make it possible to decorate class methods. When a class method gets decorated, it gets stored in a dictionary so that other class methods can reference it by a string name. Motivation: I want to implement the equivalent of ASP.Net's WebMethods. I am building this on top of google app engine, but that does not affect the point of difficulty that I am having. How it Would look if it worked: class UsefulClass(WebmethodBaseClass): def someMethod(self, blah): print(blah) @webmethod def webby(self, blah): print(blah) # the implementation of this class could be completely different, it does not matter # the only important thing is having access to the web methods defined in sub classes class WebmethodBaseClass(): def post(self, methodName): webmethods[methodName]("kapow") ... a = UsefulClass() a.post("someMethod") # should error a.post("webby") # prints "kapow" There could be other ways to go about this. I am very open to suggestions

• Django Formset validation with an optional ForeignKey field

  - by Camilo Díaz

  Having a ModelFormSet built with modelformset_factory and using a model with an optional ForeignKey, how can I make empty (null) associations to validate on that form? Here is a sample code: ### model class Prueba(models.Model): cliente = models.ForeignKey(Cliente, null = True) valor = models.CharField(max_length = 20) ### view def test(request): PruebaFormSet = modelformset_factory(model = Prueba, extra = 1) if request.method == 'GET': formset = PruebaFormSet() return render_to_response('tpls/test.html', {'formset' : formset}, context_instance = RequestContext(request)) else: formset = PruebaFormSet(request.POST) # dumb tests, just to know if validating if formset.is_valid(): return HttpResponse('0') else: return HttpResponse('1') In my template, i'm just calling the {{ form.cliente }} method which renders the combo field, however, I want to be able to choose an empty (labeled "------") value, as the FK is optional... but when the form gets submitted it doesn't validate. Is this normal behaviour? How can i make this field to skip required validation?

• Returning to last viewed List page after insert/edit with ASP.NET Dynamic Data

  - by Pat James

  With a pretty standard Dynamic Data site, when the user edits or inserts a new item and saves, the page does a Response.Redirect(table.ListActionPath), which takes the user back to page 1 of the table. If they were editing an item on page 10 (or whatever) and want to edit the next item on that page, they have to remember the page number and navigate back to it. What's the best way to return the user to the list page they last viewed? I can conceive of some solutions using cookies, session state, or query string values to retain this state and making my own Page Template to incorporate it, but I can't help thinking this must be something that was considered when Dynamic Data was created, and there must be something simpler or built-in to the framework that I'm missing here.

• django app using amazon aws s3 storage in stead of DB?

  - by farble1670

  new to python here so bear with me ... i'm looking at django for a rapid prototype to a photo sharing app with an amazon aws s3 storage back end. however, as far as i can tell, django is tailored toward the typical database MVC type of pattern. is there a way to for example provide a custom django model implementation that talks to s3 in stead of a DB? a custom DB engine? would either of these be practical, or am i looking in the wrong direction? thanks.

• WPF win app and browser app

  - by pdiddy

  I'm hearing this alot, that you can develop an app in WPF and run it as a desktop app or in a browser. Is this really true? I've install visual studio 2010 and I see 2 project templates : WPF Windows Application and WPF Browser Application (XBAP). Currently reading a book on WPF, it talks about Page-Base app, which can be use for navigation. To creatre an app to run on your browser you have to use the WPF Browser Application. So if I start with WPF Windows Application template can I run it in a browser ? I am assuming not since most of my class will be Window and not Page ....

• What is the C# equivalent of this Excel VBA code for Shapes?

  - by code4life

  This is the VBA code for an Excel template, which I'm trying to convert to C# in a VSTO project I'm working on. By the way, it's a VSTO add-in: Dim addedShapes() As Variant ReDim addedShapes(1) addedShapes(1) = aBracket.Name ReDim Preserve addedShapes(UBound(addedShapes) + 1) addedShapes(UBound(addedShapes)) = "unique2" Set tmpShape = Me.Shapes.Range(addedShapes).Group At this point, I'm stumped by the addedShapes(), not sure what this is all about. Update: Matti mentioned that addedShapes() represents a variant array in VBA. So now I'm wondering what the contents of addedShapes() should be. Would this be the correct way to call the Shapes.Range() call in C#? List<string> addedShapes = new List<string>(); ... Shape tmpShape = worksheet.Shapes.get_Range (addedShapes.Cast<object>().ToArray()).Group(); I'd appreciate anyone who's worked with VBA and C# willing to make a comment on my question & problem!
