• using paperclip with secure and non-secure files

  - by crankharder

  First off, we have this namespaced/sti'd structure for our different types of 'Media' Media< Ar::Base Media::Local < Media Media::Local::Image < Media::Local Media::Local::Csv < Media::Local etc... etc.. This is excellent since a user can have many media, and how we display each piece of media is based on the class name and a co-responding partial. But what if we have some Csv's that need to be secure? That is, they can't reside inside of public. I really hate the idea of branching Media again and doing something like this: Media::Secure < Media Media::Secure::Image < Media::Secure Media::NotSecure < Media Media::NotSecure::Image < Media::NotSecure ...where Secure and NotSecure would have different params passed to has_attached_file. Now there are two classes that represent Image and it makes my view/helper system that much more complicated -- not to mention it feels very obtuse. What I would really like to do is be able to change where certain Paperclip::Attachment objects get saved before they get saved (e.g. anything uploaded through foo_secure_action) -- but I can't seem to make this work. Paperclip::Attachment has an @options hash with :path and :url, but changing those before it is saved doesn't have an effect on where it actually gets set. Even if this is possible, I'm not sure if it would have further consequences... I'm open to alternative ideas for structuring this data, but for the moment I like the idea of using STI for this situation.

• GDI RoundRect on Compact Framework: make rounded rectangle's outside transparent.

  - by VansFannel

  Hello! I'm using the RoundRect GDI function to draw a rounded rectangle following this example: .NET CF Custom Control: RoundedGroupBox Because all controls are square, it also draw the corners outside of the rounded rectangle. How can I make this space left outside the rectangle transparent? The OnPaint method is: protected override void OnPaint(PaintEventArgs e) { int outerBrushColor = HelperMethods.ColorToWin32(m_outerColor); int innerBrushColor = HelperMethods.ColorToWin32(this.BackColor); IntPtr hdc = e.Graphics.GetHdc(); try { IntPtr hbrOuter = NativeMethods.CreateSolidBrush(outerBrushColor); IntPtr hOldBrush = NativeMethods.SelectObject(hdc, hbrOuter); NativeMethods.RoundRect(hdc, 0, 0, this.Width, this.Height, m_diametro, m_diametro); IntPtr hbrInner = NativeMethods.CreateSolidBrush(innerBrushColor); NativeMethods.SelectObject(hdc, hbrInner); NativeMethods.RoundRect(hdc, 0, 18, this.Width, this.Height, m_diametro, m_diametro); NativeMethods.SelectObject(hdc, hOldBrush); NativeMethods.DeleteObject(hbrOuter); NativeMethods.DeleteObject(hbrInner); } finally { e.Graphics.ReleaseHdc(hdc); } if (!string.IsNullOrEmpty(m_roundedGroupBoxText)) { Font titleFont = new Font("Tahoma", 9.0F, FontStyle.Bold); Brush titleBrush = new SolidBrush(this.BackColor); try { e.Graphics.DrawString(m_roundedGroupBoxText, titleFont, titleBrush, 14.0F, 2.0F); } finally { titleFont.Dispose(); titleBrush.Dispose(); } } base.OnPaint(e); } An the OnPaintBackground is: protected override void OnPaintBackground(PaintEventArgs e) { if (this.Parent != null) { SolidBrush backBrush = new SolidBrush(this.Parent.BackColor); try { e.Graphics.FillRectangle(backBrush, 0, 0, this.Width, this.Height); } finally { backBrush.Dispose(); } } } Thank you!

• RhinoMocks Testing callback method

  - by joblot

  Hi All I have a service proxy class that makes asyn call to service operation. I use a callback method to pass results back to my view model. Doing functional testing of view model, I can mock service proxy to ensure methods are called on the proxy, but how can I ensure that callback method is called as well? With RhinoMocks I can test that events are handled and event raise events on the mocked object, but how can I test callbacks? ViewModel: public class MyViewModel { public void GetDataAsync() { // Use DI framework to get the object IMyServiceClient myServiceClient = IoC.Resolve<IMyServiceClient>(); myServiceClient.GetData(GetDataAsyncCallback); } private void GetDataAsyncCallback(Entity entity, ServiceError error) { // do something here... } } ServiceProxy: public class MyService : ClientBase, IMyServiceClient { // Constructor public NertiAdminServiceClient(string endpointConfigurationName, string remoteAddress) : base(endpointConfigurationName, remoteAddress) { } // IMyServiceClient member. public void GetData(Action<Entity, ServiceError> callback) { Channel.BeginGetData(EndGetData, callback); } private void EndGetData(IAsyncResult result) { Action<Entity, ServiceError> callback = result.AsyncState as Action<Entity, ServiceError>; ServiceError error; Entity results = Channel.EndGetData(out error, result); if (callback != null) callback(results, error); } } Thanks

• CGContext - PDF margin

  - by Manoj Khaylia

  Hi All I am showing PDF content on a view using this code using Quartz Sample // PDF page drawing expects a Lower-Left coordinate system, so we flip the coordinate system // before we start drawing. CGContextTranslateCTM(context, 0.0, self.bounds.size.height); CGContextScaleCTM(context, 1.0, -1.0); // Grab the first PDF page CGPDFPageRef page = CGPDFDocumentGetPage(pdf, pageNo); // We're about to modify the context CTM to draw the PDF page where we want it, so save the graphics state in case we want to do more drawing CGContextSaveGState(context); // CGPDFPageGetDrawingTransform provides an easy way to get the transform for a PDF page. It will scale down to fit, including any // base rotations necessary to display the PDF page correctly. CGAffineTransform pdfTransform = CGPDFPageGetDrawingTransform(page, kCGPDFCropBox, self.bounds, 0, true); // And apply the transform. CGContextConcatCTM(context, pdfTransform); // Finally, we draw the page and restore the graphics state for further manipulations! CGContextDrawPDFPage(context, page); CGContextRestoreGState(context); Using this all works fine I want to set the margin for the PDF context, bydefault it showing 50 px margin in every side.. I have tried CGContext methods but not got the appropriate one. Can any body help me regarding this Thanks Monaj

• RMagic Error in rails, with AM Charts

  - by Elliot

  Hi Everyone, I'm using AMCharts and rails. AMCharts uses the Image Magic lib to export an image of the chart. In rails this is done with the gem, RMagic. In a controller this is implemented with the following controller method: def export width = params[:width].to_i height = params[:height].to_i data = {} img = Magick::Image.new(width, height) height.times do |y| row = params["r#{y}"].split(',') row.size.times do |r| pixel = row[r].to_s.split(':') pixel[0] = pixel[0].to_s.rjust(6, '0') if pixel.size == 2 pixel[1].to_i.times do (data[y] ||= []) << pixel[0] end else (data[y] ||= []) << pixel[0] end end width.times do |x| img.pixel_color(x, y, "##{data[y][x]}") end end img.format = "PNG" send_data(img.to_blob , :disposition => 'inline', :type => 'image/png', :filename => "chart.png?#{rand(99999999).to_i}") end When the controller is accessed however, I receive this error in the page: The change you wanted was rejected. Maybe you tried to change something you didn't have access to. And this error in the logs (its running on heroku btw): ActionController::InvalidAuthenticityToken (ActionController::InvalidAuthenticityToken): /home/heroku_rack/lib/static_assets.rb:9:in `call' /home/heroku_rack/lib/last_access.rb:25:in `call' /home/heroku_rack/lib/date_header.rb:14:in `call' thin (1.0.1) lib/thin/connection.rb:80:in `pre_process' thin (1.0.1) lib/thin/connection.rb:78:in `catch' thin (1.0.1) lib/thin/connection.rb:78:in `pre_process' thin (1.0.1) lib/thin/connection.rb:57:in `process' thin (1.0.1) lib/thin/connection.rb:42:in `receive_data' eventmachine (0.12.6) lib/eventmachine.rb:240:in `run_machine' eventmachine (0.12.6) lib/eventmachine.rb:240:in `run' thin (1.0.1) lib/thin/backends/base.rb:57:in `start' thin (1.0.1) lib/thin/server.rb:150:in `start' thin (1.0.1) lib/thin/controllers/controller.rb:80:in `start' thin (1.0.1) lib/thin/runner.rb:173:in `send' thin (1.0.1) lib/thin/runner.rb:173:in `run_command' thin (1.0.1) lib/thin/runner.rb:139:in `run!' thin (1.0.1) bin/thin:6 /usr/local/bin/thin:20:in `load' /usr/local/bin/thin:20 Rendering /disk1/home/slugs/149903_609c236_eb4f/mnt/public/422.html (422 Unprocessable Entity) Anyone have any idea what's going on here?

• WPF Exposing a calculated property for binding (as DependencyProperty)

  - by kubal5003

  Hello, I have a complex WPF control that for some reasons (ie. performance) is not using dependency properties but simple C# properties (at least at the top level these are exposed as properties). The goal is to make it possible to bind to some of those top level properties - I guess I should declare them as DPs.(right? or is there some other way to achieve this? ) I started reading on MSDN about DependencyProperties and DependencyObjects and found an example: public class MyStateControl : ButtonBase { public MyStateControl() : base() { } public Boolean State { get { return (Boolean)this.GetValue(StateProperty); } set { this.SetValue(StateProperty, value); } } public static readonly DependencyProperty StateProperty = DependencyProperty.Register( "State", typeof(Boolean), typeof(MyStateControl),new PropertyMetadata(false)); } If I'm right - this code enforces the property to be backed up by DependencyProperty which restricts it to be a simple property with a store(from functional point of view, not technically) instead of being able to calculate the property value each time getter is called and setting other properties/fields each time setter is called. What can I do about that? Is there any way I could make those two worlds meet at some point?

• Websphere 7 EntityManagerFactory creation problem

  - by mihaela

  Hello, I'm working on a maven project which uses seam 2.2.0, hibernate 3.5.0-CR-2 as JPA provider, DB2 as database server and Websphere 7 as application server. Now I'm facing de following problem: In my EJBs that are seen also as SEAM components I want to use the EntityManager from EJB container (@PersistenceContext private EntityManager em) not Seam's EntityManager (@In private EntityManager em). But this is the problem, I cannot obtain an EntityManager using @PersistenceContext. On server logs it sais that it cannot create an EntityManagerFactory and gets a ClassCastException: java.lang.ClassCastException: org.hibernate.ejb.HibernatePersistence incompatible with javax.persistence.spi.PersistenceProvider After a lot of debugging and searching on forums I'm assuming that the problem is that Websphere doesn't use the Hibernate JPA provider. Has anyone faced this problem and has a solution? I configured already WAS class loader order for my application to load the classes with the application class loader first and I\ve packed all necessary jars in application ear as written in: WAS InfoCenter: Features for EJB 3.0 development . If necessary I'll post my persistence.xml, components.xml files and stack trace. I've found this problem discussed also here: Websphere EntityManagerFactory creation problem Hibernate 3.3 fail to create entity manager factory in Websphere 7.0. Please help Any hint will be useful. Thanks in advance! Mihaela

• Site Security/Access management for asp.net mvc application

  - by minal

  I am trying to find a good pattern to use for user access validation. Basically on a webforms application I had a framework which used user roles to define access, ie, users were assigned into roles, and "pages" were granted access to a page. I had a table in the database with all the pages listed in it. Pages could have child pages that got their access inherited from the parent. When defining access, I assigned the roles access to the pages. Users in the role then had access to the pages. It is fairly simple to manage as well. The way I implemented this was on a base class that every page inherited. On pageload/init I would check the page url and validate access and act appropriately. However I am now working on a MVC application and need to implement something similar, however I can't find a good way to make my previous solution work. Purely because I don't have static pages as url paths. Also I am not sure how best to approach this as I now have controllers rather then aspx pages. I have looked at the MVCSitemapprovider, but that does not work off a database, it needs a sitemap file. I need control of changing user persmissions on the fly. Any thoughts/suggestions/pointers would be greatly appreciated.

• Comparing objects with IDispatch to get main frame only (BHO)

  - by shaimagz

  I don't know if anyone familiar with BHO (Browser Helper Object), but an expert in c++ can help me too. In my BHO I want to run the OnDocumentComplete() function only on the main frame - the first container and not all the Iframes inside the current page. (an alternative is to put some code only when this is the main frame). I can't find how to track when is it the main frame that being populated. After searching in google I found out that each frame has "IDispatch* pDisp", and I have to compare it with a pointer to the first one. This is the main function: STDMETHODIMP Browsarity::SetSite(IUnknown* pUnkSite) { if (pUnkSite != NULL) { // Cache the pointer to IWebBrowser2. HRESULT hr = pUnkSite->QueryInterface(IID_IWebBrowser2, (void **)&m_spWebBrowser); if (SUCCEEDED(hr)) { // Register to sink events from DWebBrowserEvents2. hr = DispEventAdvise(m_spWebBrowser); if (SUCCEEDED(hr)) { m_fAdvised = TRUE; } } } else { // Unregister event sink. if (m_fAdvised) { DispEventUnadvise(m_spWebBrowser); m_fAdvised = FALSE; } // Release cached pointers and other resources here. m_spWebBrowser.Release(); } // Call base class implementation. return IObjectWithSiteImpl<Browsarity>::SetSite(pUnkSite); } This is where I want to be aware whether its the main window(frame) or not: void STDMETHODCALLTYPE Browsarity::OnDocumentComplete(IDispatch *pDisp, VARIANT *pvarURL) { // as you can see, this function get the IDispatch *pDisp which is unique to every frame. //some code } I asked this question on Microsoft forum and I got an answer without explaining how to actually implement that: http://social.msdn.microsoft.com/Forums/en-US/ieextensiondevelopment/thread/7c433bfa-30d7-42db-980a-70e62640184c

• WebSVN with VisualSVN Server, anyone gotten authentication to work?

  - by Lasse V. Karlsen

  I have a VisualSVN Server installed on a Windows server, serving several repositories. Since the web-viewer built into VisualSVN server is a minimalistic subversion browser, I'd like to install WebSVN on top of my repositories. The problem, however, is that I can't seem to get authentication to work. Ideally I'd like my current repository authentication as specified in VisualSVN to work with WebSVN, so that though I see all the repository names in WebSVN, I can't actually browse into them without the right credentials. By visiting the cached copy of the topmost link on this google query you can see what I've found so far that looks promising. (the main blog page seems to have been destroyed, domain of the topmost page I'm referring to is the-wizzard.de) There I found some php functions I could tack onto one of the php files in WebSVN. I followed the modifications there, but all I succeeded in doing was make WebSVN ask me for a username and password and no matter what I input, it won't let me in. Unfortunately, php and apache is largely black magic to me. So, has anyone successfully integrated WebSVN with VisualSVN hosted repositories?

• Android - Views in Custom Compound Component are not inflated (findByView returns null)

  - by Julian Arz

  I have made a Custom Component in XML, consisting of a button with an imageview stacked on top of it: <myapp.widget.ClearableCaptionedButton xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="wrap_content" android:layout_height="wrap_content"> <Button android:id="@+id/ccbutton_button" android:layout_width="fill_parent" android:layout_height="wrap_content" android:gravity="center_vertical|left" android:textAppearance="?android:attr/textAppearanceMedium" android:background="@android:drawable/edit_text"/> <ImageView android:id="@+id/ccbutton_clear" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginRight="5dip" android:layout_alignRight="@id/ccbutton_button" android:layout_alignTop="@id/ccbutton_button" android:layout_alignBottom="@id/ccbutton_button"/> </myapp.widget.ClearableCaptionedButton> extract of java source code: public class ClearableCaptionedButton extends RelativeLayout implements OnClickListener { ... public ClearableCaptionedButton(Context context, AttributeSet attrs) { super(context, attrs); // some stuff that works fine } .. protected void onFinishInflate() { super.onFinishInflate(); mButton = (Button) findViewById(R.id.ccbutton_button); mClear = (ImageView) findViewById(R.id.ccbutton_clear); mButton.setText(""); // error here: mButton == null } My problem is similar to this one. When i try to find the views inside the custom compound, findViewById returns null. But, as you can see, i already added super(context, attrs); to the constructor. i am using the custom component directly in xml layout, like this: <LinearLayout> <!-- some stuff --> <de.pockettaxi.widget.ClearableCaptionedButton android:layout_width="fill_parent" android:layout_height="wrap_content" app:caption="to"/> </LinearLayout> can anybody spot something? thanks.

• Problem with DOMPDF and Kohana 3

  - by alex

  I have used DOMPDF many times before successfully, however outside of the Kohana Framework. I created a module for DOMPDF and called it simply pdf. Here is it's code. class Pdf { private $domPdfInstance; public function __construct($html) { if ( ! class_exists('DOMPDF', FALSE)) { // Load DOMPDF require Kohana::find_file('vendor', 'dompdf/dompdf_config.inc'); } $this->domPdfInstance = new DOMPDF; $this->domPdfInstance->load_html($html); } public function render() { $this->domPdfInstance->render(); return $this; } public function stream($filename) { if (pathinfo($filename, PATHINFO_EXTENSION) !== 'pdf') { $filename .= '.pdf'; } $this->domPdfInstance->stream($filename); return $this; } } For some reason, any PDF I generate using this results in it being corrupt (not opening under Mac OS X's Preview app at least). I have even tried this basic HTML <html> <head> <title>PDF</title> </head> <body> please work </body> </html> Is this a known problem? I have not touched anything in dompdf_config.inc.php except uncomment out the error reporting levels so they now read error_reporting(E_STRICT | E_ALL); PHP is not reporting any errors. Here is a screenshot of the error from Preview (though I think it's probably unhelpful) Some thing I have thought may be a problem Auto loading conflicts Base path conflicts

• How to pass a reference to a JS function as an argument to an ExternalInterface call?

  - by Ryan Wilson

  Summary I want to be able to call a JavaScript function from a Flex app using ExternalInterface and pass a reference to a different JavaScript function as an argument. Base Example Given the following JavaScript: function foo(callback) { // ... do some stuff callback(); } function bar() { // do some stuff that should happen after a call to foo } I want to call foo from my flex app using ExternalInterface and pass a reference to bar as the callback. Why Really,foo is not my function (but, rather, FB.Connect.showBookmarkDialog), which due to restrictions on Facebook iframe apps can only be called on a button click. My button, for design reasons, is in the Flex app. Fortunately, it's possible to call ExternalInterface.call("FB.Connect.showBookmarkDialog", callback) to display the bookmark dialog. But, FB.Connect.showBookmarkDialog requires a JS callback so, should I want to receive a callback (which I do), I need to pass a reference to a JS function as the single argument. Real Example MXML: <mx:Button click="showBookmarkDialog();" /> ActionScript: function showBookmarkDialog() : void { ExternalInterface.registerCallback( "onBookmarkDialogClosed", onBookmarkDialogClosed ); ExternalInterface.call( "FB.Connect.showBookmarkDialog", /* ref to JS function onBookmarkDialogClosed ? */ ); } function onBookmarkDialogClosed(success:Boolean) : void { // sweet, we made it back } JavaScript: function onBookmarkDialogClosed() { var success; // determine value of success getSWF().onBookmarkDialogClosed(success); } Failed Experiments I have tried... ExternalInterface.call( "FB.Connect.showBookmarkDialog", "onBookmarkDialogClosed" ); ExternalInterface.call( "FB.Connect.showBookmarkDialog", onBookmarkDialogClosed ); ExternalInterface.call( "FB.Connect.showBookmarkDialog", function() : void { ExternalInterface.call("onBookmarkDialogClosed"); } ); ExternalInterface.call( "FB.Connect.showBookmarkDialog", function() { this["onBookmarkDialogClosed"](); } ); Of note: Passing a string as the argument to an ExternalInterface call results in FB's JS basically trying to do `"onBookmarkDialogClosed"()` which, needless to say, will not work. Passing a function as the argument results in a function object on the other side (confirmable with `typeof`), but it seems to be an empty function; namely, `function Function() {}`

• Reflective Generic Detection

  - by Aren B

  Trying to find out if a provided Type is of a given generic type (with any generic types inside) Let me Explain: bool IsOfGenericType(Type baseType, Type sampleType) { /// ... } Such that: IsOfGenericType(typeof(Dictionary<,>), typeof(Dictionary<string, int>)); // True IsOfGenericType(typeof(IDictionary<,>), typeof(Dictionary<string, int>)); // True IsOfGenericType(typeof(IList<>), typeof(Dictionary<string,int>)); // False However, I played with some reflection in the intermediate window, here were my results: typeof(Dictionary<,>) is typeof(Dictionary<string,int>) Type expected typeof(Dictionary<string,int>) is typeof(Dictionary<string,int>) Type expected typeof(Dictionary<string,int>).IsAssignableFrom(typeof(Dictionary<,>)) false typeof(Dictionary<string,int>).IsSubclassOf(typeof(Dictionary<,>)) false typeof(Dictionary<string,int>).IsInstanceOfType(typeof(Dictionary<,>)) false typeof(Dictionary<,>).IsInstanceOfType(typeof(Dictionary<string,int>)) false typeof(Dictionary<,>).IsAssignableFrom(typeof(Dictionary<string,int>)) false typeof(Dictionary<,>).IsSubclassOf(typeof(Dictionary<string,int>)) false typeof(Dictionary<,>) is typeof(Dictionary<string,int>) Type expected typeof(Dictionary<string,int>) is typeof(Dictionary<string,int>) Type expected typeof(Dictionary<string,int>).IsAssignableFrom(typeof(Dictionary<,>)) false typeof(Dictionary<string,int>).IsSubclassOf(typeof(Dictionary<,>)) false typeof(Dictionary<string,int>).IsInstanceOfType(typeof(Dictionary<,>)) false typeof(Dictionary<,>).IsInstanceOfType(typeof(Dictionary<string,int>)) false typeof(Dictionary<,>).IsAssignableFrom(typeof(Dictionary<string,int>)) false typeof(Dictionary<,>).IsSubclassOf(typeof(Dictionary<string,int>)) false So now I'm at a loss because when you look at the base.Name on typeof(Dictionary) you get Dictionary`2 Which is the same as typeof(Dictionary<,>).Name

• How to create mobile substrate plugins on XCode?

  - by prathumca

  Hi Everyone, I just wanna create a MS plugin to hook SpringBoard. I'm following "gojohnnyboi" tutorial from here "http://www.ipodtouchfans.com/forums/showthread.php?t=103558". To create a dylib on XCode, I'm following "SkylarEC" tutorial. I mix these two great tutorials and finally got succeed by getting a dylib. But when I placed the dylib in the /Library/MobileSubstrate/DynamicLibraries/ nothing is happened (no alert was shown). By evaluating, I found that, this dylib doesn't have any starting point when it was loaded into the memory. So I mentioned a starting point by declaring a constructor in the .mm file like, __ attribute__((constructor)) static void init() { Class _$SBAppIcon = objc_getClass("SBApplicationIcon"); MSHookMessage($SBAppIcon, @selector(launch), (IMP) &_$ExampleHook_AppIcon_Launch, "_OriginalMethodPrefix"); } But when I'm trying to compile this, I'm getting an error like, Undefined symbols: "_MSHookMessage", referenced from: init() in ExampleHook.o ld: symbol(s) not found collect2: ld returned 1 exit status. Does anyone has idea how to solve this? It would be great and more helpful if anyone share the detailed tutorial/instructions to create a dylib on XCode. P.S I placed all the libsubstrate.dylib and substrate.h files in the corresponding location. And the locations are, libsubstrate.dylib : /Developer/Platforms/iPhoneOS.platform/Developer/usr/lib/ substrate.h : /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS3.0.sdk/usr/include and my base SDK is 3.0.

• Mapping a collection of enums with NHibernate

  - by beaufabry

  Mapping a collection of enums with NHibernate Specifically, using Attributes for the mappings. Currently I have this working mapping the collection as type Int32 and NH seems to take care of it, but it's not exactly ideal. The error I receive is "Unable to determine type" when trying to map the collection as of the type of the enum I am trying to map. I found a post that said to define a class as public class CEnumType : EnumStringType { public CEnumType() : base(MyEnum) { } } and then map the enum as CEnumType, but this gives "CEnumType is not mapped" or something similar. So has anyone got experience doing this? So anyway, just a simple reference code snippet to give an example with [NHibernate.Mapping.Attributes.Class(Table = "OurClass")] public class CClass : CBaseObject { public enum EAction { do_action, do_other_action }; private IList<EAction> m_class_actions = new List<EAction>(); [NHibernate.Mapping.Attributes.Bag(0, Table = "ClassActions", Cascade="all", Fetch = CollectionFetchMode.Select, Lazy = false)] [NHibernate.Mapping.Attributes.Key(1, Column = "Class_ID")] [NHibernate.Mapping.Attributes.Element(2, Column = "EAction", Type = "Int32")] public virtual IList<EAction> Actions { get { return m_class_actions; } set { m_class_actions = value;} } } So, anyone got the correct attributes for me to map this collection of enums as actual enums? It would be really nice if they were stored in the db as strings instead of ints too but it's not completely necessary.

• Did I find a bug in WriteableBitmap when using string literals

  - by liserdarts

  For performance reasons I'm converting a large list of images into a single image. This code does exactly what I want. Private Function FlattenControl(Control As UIElement) As Image Control.Measure(New Size(1000, 1000)) Control.Arrange(New Rect(0, 0, 1000, 1000)) Dim ImgSource As New Imaging.WriteableBitmap(1000, 1000) ImgSource.Render(Control, New TranslateTransform) ImgSource.Invalidate Dim Img As New Image Img.Source = ImgSource Return Img End Function I can add all the images into a canvas pass the canvas to this function and I get back one image. My code to load all the images looks like this. Public Function BuildTextures(Layer As GLEED2D.Layer) As FrameworkElement Dim Container As New Canvas For Each Item In Layer.Items If TypeOf Item Is GLEED2D.TextureItem Then Dim Texture = CType(Item, GLEED2D.TextureItem) Dim Url As New Uri(Texture.texture_filename, UriKind.Relative) Dim Img As New Image Img.Source = New Imaging.BitmapImage(Url) Container.Children.Add(Img) End If Next Return FlattenControl(Container) End Function The GLEED2D.Layer and GLEED2D.TextureItem classes are from the free level editor GLEED2D (http://www.gleed2d.de/). The texture_filename on every TextureItem is "Images/tree_clipart_pine_tree.png" This works just fine, but it's just a proof of concept. What I really need to do (among other things) is have the path to the image hard coded. If I replace Texture.texture_filename in the code above with the string literal "Images/tree_clipart_pine_tree.png" the images do not appear in the final merged image. I can add a breakpoint and see that the WriteableBitmap has all of it's pixels as 0 after the call to Invalidate. I have no idea how this could cause any sort of difference, but it gets stranger. If I remove the call to FlattenControl and just return the Canvas instead, the images are visible. It's only when I use the string literal with the WriableBitmap that the images do not appear. I promise you that the value in the texture_filename property is exactly "Images/tree_clipart_pine_tree.png". I'm using Silverlight 3 and I've also reproduced this in Silverlight 4. Any ideas?

• Regression Testing and Deployment Strategy

  - by user279516

  I'd like some advice on a deployment strategy. If a development team creates an extensive framework, and many (20-30) applications consume it, and the business would like application updates at least every 30 days, what is the best deployment strategy? The reason I ask is that there seems to be a lot of waste (and risk) in using an agile approach of deploying changes monthly, if 90% of the applications don't change. What I mean by this is that the framework can change during the month, and so can a few applications. Because the framework changed, all applications should be regression-tested. If, say, 10 of the applications don't change at all during the year, then those 10 applications are regression-tested EVERY MONTH, when they didn't have any feature changes or hot fixes. They had to be tested simply because the business is rolling updates every month. And the risk that is involved... if a mission-critical application is deployed, that takes a few weeks, and multiple departments, to test, is it realistic to expect to have to constantly regression-test this application? One option is to make any framework updates backward-compatible. While this would mean that applications don't need to change their code, they would still need to be tested because the underlying framework changed. And the risk involved is great; a constantly changing framework (and deploying this framework) means the mission-critical app can never just enjoy the same code base for a long time. These applications share the same database, hence the need for the constant testing. I'm aware of TDD and automated tests, but that doesn't exist at the moment. Any advice?

• Command-Line Parsing API from TestAPI library - Type-Safe Commands how to

  - by MicMit

  Library at http://testapi.codeplex.com/ Excerpt of usage from http://blogs.msdn.com/ivo_manolov/archive/2008/12/17/9230331.aspx A third common approach is forming strongly-typed commands from the command-line parameters. This is common for cases when the command-line looks as follows: some-exe COMMAND parameters-to-the-command The parsing in this case is a little bit more involved: Create one class for every supported command, which derives from the Command abstract base class and implements an expected Execute method. Pass an expected command along with the command-line arguments to CommandLineParser.ParseCommand – the method will return a strongly-typed Command instance that can be Execute()-d. // EXAMPLE #3: // Sample for parsing the following command-line: // Test.exe run /runId=10 /verbose // In this particular case we have an actual command on the command-line (“run”), which we want to effectively de-serialize and execute. public class RunCommand : Command { bool? Verbose { get; set; } int? RunId { get; set; } public override void Execute() { // Implement your "run" execution logic here. } } Command c = new RunCommand(); CommandLineParser.ParseArguments(c, args); c.Execute(); ============================ I don't get if we instantiate specific class before parsing arguments , what's the point of command line argument "run" which is very first one. I thought the idea was to instantiate and execute command/class based on a command line parameter ( "run" parameter becomes instance RunCommand class, "walk" becomes WalkCommand class and so on ). Can it be done with the latest version ?

• WOT Bookmarklet

  - by S.A

  I'm trying to write a bookmarklet that will allow me to view the Web Of Trust (WOT) ratings for all the links on a page before visiting them. While WOT provides their own bookmarklet, it is not very useful since you need to visit the page first before viewing the rating. This will be used on SeaMonkey, so I can't just install the WOT extension, either. WOT has a Javascript API that allows you to activate the ratings on any page it is included in, so I am using that as a base. However, it never seems to work correctly as a bookmarklet. Here's one attempt where I tried to keep the code as close to the API as possible. I only modified the wotinject function so that it would work in a bookmarklet and added a timeout so that the rating widget wouldn't be loaded before jQuery. var wotprotocol = (document.location.protocol == "https:") ? "https://" : "http://"; var wotbase = wotprotocol + "api.mywot.com/widgets"; var wotinject = function(src) { document.body.appendChild(document.createElement("script")).src = wotbase + "/" + src + ".js"; }; var wotjquery = typeof(jQuery) != "undefined"; if (!wotjquery) { wotinject("jquery"); } void(window.setTimeout(wotinject, 200, "ratingwidget")); I can see the APIs being loaded in the status bar, but it doesn't do anything at all. Is there any way to get this working?

• How to avoid XCode framework weak-linking problems?

  - by Frank R.

  Hi, I'm building an application that takes advantage of Mac OS X 10.6-only technologies, but without giving up backwards compatibility to 10.5 Leopard. The way I do this is by setting the 10.6 SDK as the base SDK, weak-linking all frameworks and setting the deployment target to 10.5 as described in: http://developer.apple.com/mac/library/DOCUMENTATION/MacOSX/Conceptual/BPFrameworks/Concepts/WeakLinking.html This works fine; before making a call that is Snow Leopard-only I need to check that the selector or indeed the class actually exist. Or I can just check the OS version before making the call. The problem is that this is incredibly fragile. If I make a single call that is 10.6 only I blow Leopard-compatibility. So using even the normal code code completion feature can be dangerous. My question: is there any way of checking which calls are not defined on 10.5 before doing a release build? Some kind of static analysis, or even just a trick (a target set the other SDK?) would do. I obviously should test on a Leopard machine before releasing anything, but even so I can't possibly go through all paths of the program before every release. Any advice would be appreciated. Best regards, Frank

• Possible to create an implicit cast for an anonymous type to a dictionary?

  - by Ralph

  I wrote a method like this: using AttrDict = System.Collections.Generic.Dictionary<string, object>; using IAttrDict = System.Collections.Generic.IEnumerable<System.Collections.Generic.KeyValuePair<string, object>>; static string HtmlTag(string tagName, string content = null, IAttrDict attrs = null) { var sb = new StringBuilder("<"); sb.Append(tagName); if(attrs != null) foreach (var attr in attrs) sb.AppendFormat(" {0}=\"{1}\"", attr.Key, attr.Value.ToString().EscapeQuotes()); if (content != null) sb.AppendFormat(">{0}</{1}>", content, tagName); else sb.Append(" />"); return sb.ToString(); } Which you can call like HtmlTag("div", "hello world", new AttrDict{{"class","green"}}); Not too bad. But what if I wanted to allow users to pass an anonymous type in place of the dict? Like HtmlTag("div", "hello world", new {@class="green"}); Even better! I could write the overload easily, but the problem is I'm going to have about 50 functions like this, I don't want to overload each one of them. I was hoping I could just write an implicit cast to do the work for me... public class AttrDict : Dictionary<string, object> { public static implicit operator AttrDict(object obj) { // conversion from anonymous type to AttrDict here } } But C# simply won't allow it: user-defined conversions to or from a base class are not allowed So what can I do?
