• Custom DataAnnotation attribute with datastore access in ASP.NET MVC 2

  - by mare

  I have my application designed with Repository pattern implemented and my code prepared for optional dependency injection in future, if we need to support another datastore. I want to create a custom validation attribute for my content objects. This attribute should perform some kind of datastore lookup. For instance, I need my content to have unique slugs. To check if a Slug already exist, I want to use custom DataAnnotation attribute in my Base content object (instead of manually checking if a slug exists each time in my controller's Insert actions). Attribute logic would do the validation. So far I have come up with this: public class UniqueSlugAttribute : ValidationAttribute { private readonly IContentRepository _repository; public UniqueSlugAttribute(ContentType contentType) { _repository = new XmlContentRepository(contentType); } public override bool IsValid(object value) { if (string.IsNullOrWhiteSpace(value.ToString())) { return false; } string slug = value.ToString(); if(_repository.IsUniqueSlug(slug)) return true; return false; } } part of my Base content class: ... [DataMember] public ContentType ContentType1 { get; set; } [DataMember] [Required(ErrorMessageResourceType = typeof (Localize), ErrorMessageResourceName = "Validation_SlugIsBlank")] [UniqueSlug(ContentType1)] public string Slug { get { return _slug; } set { if (!string.IsNullOrEmpty(value)) _slug = Utility.RemoveIllegalCharacters(value); } } ... There's an error in line [UniqueSlug(ContentType1)] saying: "An attribute argument must be a constant expression, typeof expression or array creation expression of an attribute parameter type." Let me explain that I need to provide the ContentType1 parameter to the Constructor of UniqueSlug class because I use it in my data provider. It is actually the same error that appears if you try do to this on the built-in Required attribute: [Required(ErrorMessageResourceType = typeof (Localize), ErrorMessageResourceName = Resources.Localize.SlugRequired] It does not allow us to set it to dynamic content. In the first case ContentType1 gets known at runtime, in the second case the Resources.Localize.SlugRequired also gets known at runtime (because the Culture settings are assigned at runtime). This is really annoying and makes so many things and implementation scenarios impossible. So, my first question is, how to get rid of this error? The second question I have, is whether you think that I should redesign my validation code in any way?

• Getting information of a class structure at runtime using Java reflection

  - by Eliza Sahoo

  A simple way to get the class structure information of the Class we are using in our application. Step1: Create the Class object of the class we want to explore at run time or the class which is getting added at runtime. Step2: As we are looking for the structure of the class, get all Constructors, Fields and methods by invoking respective functions of the Class. Step3: print them in java console or use them as required. Eliza

• Inheritance with POCO entities in Entity Framework 4

  - by Juvaly

  Hi All, I have a Consumer class and a BillableConsumer : Consumer class. When trying to do any operation on my "Consumers" set, I get the error message "Object mapping could not be found for Type with identity Models.BillableConsumer. From the CSDL: <EntityType Name="BillableConsumer" BaseType="Models.Consumer"> <Property Type="String" Name="CardExpiratoin" Nullable="false" /> <Property Type="String" Name="CardNumber" Nullable="false" /> <Property Type="String" Name="City" Nullable="false" /> <Property Type="String" Name="Country" Nullable="false" /> <Property Type="String" Name="CVV" Nullable="false" /> <Property Type="String" Name="NameOnCard" Nullable="false" /> <Property Type="String" Name="PostalCode" Nullable="false" /> <Property Type="String" Name="State" /> <Property Type="String" Name="StreetAddress" Nullable="false" /> </EntityType> From the C-S: <EntitySetMapping Name="Consumers"> <EntityTypeMapping TypeName="IsTypeOf(Models.Consumer)"> <MappingFragment StoreEntitySet="consumer"> <ScalarProperty Name="LoginID" ColumnName="LoginID" /> <ScalarProperty Name="FirstName" ColumnName="FirstName" /> <ScalarProperty Name="LastName" ColumnName="LastName" /> </MappingFragment> </EntityTypeMapping> <EntityTypeMapping TypeName="IsTypeOf(Models.BillableConsumer)"> <MappingFragment StoreEntitySet="billinginformation"> <ScalarProperty Name="CardExpiratoin" ColumnName="CardExpiratoin" /> <ScalarProperty Name="CardNumber" ColumnName="CardNumber" /> <ScalarProperty Name="City" ColumnName="City" /> <ScalarProperty Name="Country" ColumnName="Country" /> <ScalarProperty Name="CVV" ColumnName="CVV" /> <ScalarProperty Name="LoginID" ColumnName="LoginID" /> <ScalarProperty Name="NameOnCard" ColumnName="NameOnCard" /> <ScalarProperty Name="PostalCode" ColumnName="PostalCode" /> <ScalarProperty Name="State" ColumnName="State" /> <ScalarProperty Name="StreetAddress" ColumnName="StreetAddress" /> </MappingFragment> </EntityTypeMapping> </EntitySetMapping> Is this because I did not specifically add the BillableConsumer entity to the object set? How do I do that in a POCO scenario? Thanks! UPDATE: I decided to test whether or not POCOs generated with the T4 template would solve the problem and they did. The most annoying part is that when I restored my original classes from SVN to try and figure out how they are different - they worked as well!! Not adding this as an answer because someone else might have an actual explanation...

• [AS3/C#] Byte encryption ( DES-CBC zero pad )

  - by mark_dj

  Hi there, Currently writing my own AMF TcpSocketServer. Everything works good so far i can send and recieve objects and i use some serialization/deserialization code. Now i started working on the encryption code and i am not so familiar with this stuff. I work with bytes , is DES-CBC a good way to encrypt this stuff? Or are there other more performant/secure ways to send my data? Note that performance is a must :). When i call: ReadAmf3Object with the decrypter specified i get an: InvalidOperationException thrown by my ReadAmf3Object function when i read out the first byte the Amf3TypeCode isn't specified ( they range from 0 to 16 i believe (Bool, String, Int, DateTime, etc) ). I got Typecodes varying from 97 to 254? Anyone knows whats going wrong? I think it has something to do with the encryption part. Since the deserializer works fine w/o the encryption. I am using the right padding/mode/key? I used: http://code.google.com/p/as3crypto/ as as3 encryption/decryption library. And i wrote an Async tcp server with some abuse of the threadpool ;) Anyway here some code: C# crypter initalization code System.Security.Cryptography.DESCryptoServiceProvider crypter = new DESCryptoServiceProvider(); crypter.Padding = PaddingMode.Zeros; crypter.Mode = CipherMode.CBC; crypter.Key = Encoding.ASCII.GetBytes("TESTTEST"); AS3 private static var _KEY:ByteArray = Hex.toArray(Hex.fromString("TESTTEST")); private static var _TYPE:String = "des-cbc"; public static function encrypt(array:ByteArray):ByteArray { var pad:IPad = new NullPad; var mode:ICipher = Crypto.getCipher(_TYPE, _KEY, pad); pad.setBlockSize(mode.getBlockSize()); mode.encrypt(array); return array; } public static function decrypt(array:ByteArray):ByteArray { var pad:IPad = new NullPad; var mode:ICipher = Crypto.getCipher(_TYPE, _KEY, pad); pad.setBlockSize(mode.getBlockSize()); mode.decrypt(array); return array; } C# read/unserialize/decrypt code public override object Read(int length) { object d; using (MemoryStream stream = new MemoryStream()) { stream.Write(this._readBuffer, 0, length); stream.Position = 0; if (this.Decrypter != null) { using (CryptoStream c = new CryptoStream(stream, this.Decrypter, CryptoStreamMode.Read)) using (AmfReader reader = new AmfReader(c)) { d = reader.ReadAmf3Object(); } } else { using (AmfReader reader = new AmfReader(stream)) { d = reader.ReadAmf3Object(); } } } return d; }

• SmartGWT Program not displaying getting wnd.isc.Browser is null

  - by Holograham

  When running my gwt program in GWT Development Mode it fails to display showing this error in the console: com.google.gwt.core.client.JavaScriptException: (TypeError): '$wnd.isc.Browser' is null or not an object I do not believe the error is due to my project setup. Other member of the team can compile fine. It is most likely some type of config problem on my end. I have re-checked out the project and still get the error. I am using the latest jdk 1.6.0_19 if that matters

• How to access SVG elements with Javascript

  - by gargantaun

  I'm messing around with SVG and I was hoping I could create SVG files in Illustrator and access elements with Javascript.

• Why is drawing to OnPaint graphics faster than image graphics?

  - by Tesserex

  I'm looking for a way to speed up the drawing of my game engine, which is currently the significant bottleneck, and is causing slowdowns. I'm on the verge of converting it over to XNA, but I just noticed something. Say I have a small image that I've loaded. Image img = Image.FromFile("mypict.png"); We have a picturebox on the screen we want to draw on. So we have a handler. pictureBox1.Paint += new PaintEventHandler(pictureBox1_Paint); I want our loaded image to be tiled on the picturebox (this is for a game, after all). Why on earth is this code: void pictureBox1_Paint(object sender, PaintEventArgs e) { for (int y = 0; y < 16; y++) for (int x = 0; x < 16; x++) e.Graphics.DrawImage(image, x * 16, y * 16, 16, 16); } over 25 TIMES FASTER than this code: Image buff = new Bitmap(256, 256, PixelFormat.Format32bppPArgb); // actually a form member void pictureBox1_Paint(object sender, PaintEventArgs e) { using (Graphics g = Graphics.FromImage(buff)) { for (int y = 0; y < 16; y++) for (int x = 0; x < 16; x++) g.DrawImage(image, x * 16, y * 16, 16, 16); } e.Graphics.DrawImage(buff, 0, 0, 256, 256); } To eliminate the obvious, I've tried commenting out the last e.Graphics.DrawImage (which means I don't see anything, but it gets rid a call that isn't in the first example). I've also left in the using block (needlessly) in the first example, but it's still just as blazingly fast. I've set properties of g to match e.Graphics - things like InterpolationMode, CompositingQuality, etc, but nothing I do bridges this incredible gap in performance. I can't find any difference between the two Graphics objects. What gives? My test with a System.Diagnostics.Stopwatch says that the first code snippet runs at about 7100 fps, while the second runs at a measly 280 fps. My reference image is VS2010ImageLibrary\Objects\png_format\WinVista\SecurityLock.png, which is 48x48 px, and which I modified to be 72 dpi instead of 96, but those made no difference either.

• Right-click context menu for Java JTree?

  - by arcanex

  I'm trying to implement pop-up menus in Java JTree. I've sub-classed DefaultTreeCellRenderer (to change node appearance) and DefaultTreeCellEditor (to create Components to attach event listeners to, since apparently the Components that DefaultTreeCellRenderer.getTreeCellRendererComponent() returns can't do it?). I don't really want to "edit" the nodes, just be able to pop-up a menu when a node gets right-clicked, but this is the only way I can think of doing it right now... Below is the code that I have so far-- I'm just trying to figure out how to capture MouseEvents. It sort of works, but badly. What's a better way to accomplish what I'm trying to do here? private class My_TreeCellRenderer extends DefaultTreeCellRenderer { My_TreeCellRenderer() { super (); } public Component getTreeCellRendererComponent(JTree tree, Object value, boolean selected, boolean expanded, boolean leaf, int row, boolean hasFocus) { super.getTreeCellRendererComponent(tree, value, selected, expanded, leaf, row, hasFocus); // set label text and tool tips setText(((My_Object)value).getTreeLabel()); setToolTipText(((My_Object)value).getTreeToolTip()); return this; } } private class My_TreeCellEditor extends DefaultTreeCellEditor { private MouseAdapter ma; My_TreeCellEditor(JTree tree, DefaultTreeCellRenderer renderer) { super (tree, renderer); ma = new MouseAdapter() { public void mousePressed(MouseEvent e) { if (e.isPopupTrigger()) { System.out.println("My Popup"); } } public void mouseReleased(MouseEvent e) { if (e.isPopupTrigger()) { System.out.println("My Popup"); } } }; } public Component getTreeCellEditorComponent(JTree tree, Object value, boolean selected, boolean expanded, boolean leaf, int row) { String src_filename = null; // return non-editing component Component c = renderer.getTreeCellRendererComponent(tree, value, selected, expanded, leaf, row, true); // add mouse listener if it's not listening already MouseListener mouseListeners[] = c.getMouseListeners(); int i; for (i=0; i < mouseListeners.length && mouseListeners[i] != ma; i++); if (i >= mouseListeners.length) c.addMouseListener(ma); return c; } protected boolean canEditImmediately(EventObject event) { if (event instanceof MouseEvent && ((MouseEvent)event).getClickCount() == 1) return true; else return false; } }

• Java RMI method synchronization

  - by James Moore

  Hello, I have a class that is stored on the 'server' and multiple clients can call this method. This method returns a class. Now when clients call accessor methods within this class for example a set accessor method. I want the object on the server to be updated and synchronized across all the other clients. How do I use: public synchronized setStatus(String s) { this.status = s; } within java to achieve this. Thanks

• Cross-table linq query with EF4/POCO

  - by Basiclife

  Hi All, I'm new to EF(any version) and POCO. I'm trying to use POCO entities with a generic repository in a "code-first" mode(?) I've got some POCO Entities (no proxies, no lazy loading, nothing). I have a repository(of T as Entity) which provides me with basic get/getsingle/getfirst functionality which takes a lambda as a parameter (specifically a System.Func(Of T, Boolean)) Now as I'm returning the simplest possible POCO object, none of the relationship parameters work once they've been retrieved from the database (as I would expect). However, I had assumed (wrongly) that my lambda query passed to the repository would be able to use the links between entities as it would be executed against the DB before the simple POCO entities are generated. The flow is: GUI calls: Public Function GetAllTypesForCategory(ByVal CategoryID As Guid) As IEnumerable(Of ItemType) Return ItemTypeRepository.Get(Function(x) x.Category.ID = CategoryID) End Function Get is defined in Repository(of T as Entity): Public Function [Get](ByVal Query As System.Func(Of T, Boolean)) As IEnumerable(Of T) Implements Interfaces.IRepository(Of T).Get Return ObjectSet.Where(Query).ToList() End Function The code doesn't error when this method is called but does when I try to use the result set. (This seems to be a lazy loading behaviour so I tried adding the .ToList() to force eager loading - no difference) I'm using unity/IOC to wire it all up but I believe that's irrelevant to the issue I'm having NB: Relationships between entities are being configured properly and if I turn on proxies/lazy loading/etc... this all just works. I'm intentionally leaving all that turned off as some calls to the BL will be from a website but some will be via WCF - So I want the simplest possible objects. Also, I don't want a change in an object passed to the UI to be committed to the DB if another BL method calls Commit() Can someone please either point out how to make this work or explain why it's not possible? All I want to do is make sure the lambda I pass in is performed against the DB before the results are returned Many thanks. In case it matters, the container is being populated with everything as shown below: Container.AddNewExtension(Of EFRepositoryExtension)() Container.Configure(Of IEFRepositoryExtension)(). WithConnection(ConnectionString). WithContextLifetime(New HttpContextLifetimeManager(Of IObjectContext)()). ConfigureEntity(New CategoryConfig(), "Categories"). ConfigureEntity(New ItemConfig()). ... )

• How do I stop XElement.Save from escaping characters?

  - by Daniel I-S

  I'm populating an XElement with information and writing it to an xml file using the XElement.Save(path) method. At some point, certain characters in the resulting file are being escaped - for example, > becomes &gt;. This behaviour is unacceptable, since I need to store information in the XML that includes the > character as part of a password. How can I write the 'raw' content of my XElement object to XML without having these escaped?

• How can I define a clojure type that implements the servlet interface?

  - by Rob Lachlan

  I'm attempting to use deftype (from the bleeding-edge clojure 1.2 branch) to create a java class that implements the java Servlet interface. I would expect the code below to compile (even though it's not very useful). (ns foo [:import [javax.servlet Servlet ServletRequest ServletResponse]]) (deftype servlet [] javax.servlet.Servlet (service [this #^javax.servlet.ServletRequest request #^javax.servlet.ServletResponse response] nil)) But it doesn't compile. The compiler produces the message: Mismatched return type: service, expected: void, had: java.lang.Object [Thrown class java.lang.IllegalArgumentException] Which doesn't make sense to me, because I'm returning nil. So the fact that the return type of the method is void shouldn't be a problem. For instance, for the java.util.Set interface: (deftype bar [#^Number n] java.util.Set (clear [this] nil)) compiles without issue. So what am I doing wrong with the Servlet interface? To be clear: I know that the typical case is to subclass one of the servlet abstract classes rather than implement this interface directly, but it should still be possible to do this. Stack Trace: The stack trace for the (deftype servlet... is: Mismatched return type: service, expected: void, had: java.lang.Object [Thrown class java.lang.IllegalArgumentException] Restarts: 0: [ABORT] Return to SLIME's top level.

• Secondary monitor bug: a problem in WPF or in the graphics driver?

  - by emddudley

  I have discovered a strange bug with my WPF application and I am trying to determine whether it is a problem with WPF or my graphics driver so that I can report it to the appropriate company. I have a Quadro FX 1700 with the latest drivers (197.54) on a Windows XP system, running a .NET 3.5 SP1 application. I have dual monitors, and when I maximize then minimize a child window of the main window on my primary monitor, the child window gets drawn on the secondary monitor as well. It appears in both places. I made a sample application (code is below) which induces this behavior. Start the application and ensure the main window is on your primary monitor. Double-click the main window. A green child window should appear. Click the green child window to maximize. Click the green child window to minimize. Can anyone else reproduce this problem? On my system the green child restores, but then it's drawn on both my primary and secondary monitors, rather than just the primary monitor.

• Optional parameters with PHP SoapClient class on wsdl mode

  - by Maraino

  With the SoapClient class on PHP5.x and working against a SOAP web service that has optional parameters in its methods, you won't have any problem if you use the non-wsdl mode. But, at least by default, with the wsdl mode, if you don't fill all the parameters you will get an error like: SOAP-ERROR: Encoding: object hasn't 'xxx' property Is there any way to avoid that error without working with the non-wsdl mode and without filling all the parameters?

• .NET Interface with AutoCAD -- SetXData errors.

  - by Jerry

  I am trying to use the SetXData method on the AutoCAD 2007 COM object, but it is throwing errors. Example Test: public AcadEntity getAcadEntity() { /// ... Basic code to return a single AutoCAD entity... } private void btnTagItem_Click(object sender, EventArgs e) { AcadEntity ent = getAcadEntity(); short[] xDataType; string[] xDataStrings; DrawingXData xData = new DrawingXData(); xData.field1 = "Some Text Goes here"; xData.field2 = 1; xData.field3 = 100; xData.field4 = 1509.2; xData.field5 = "More Text"; BuildXData("AutoCad_App_Name", xData, out xDataType, out xDataStrings); ent.SetXData(xDataType, xDataStrings); // This line crashes. } private void BuildXData(string applicationName, DrawingXData xData, out short[] xDataType, out string[] xDataStrings) { List<short> dataTypes = new List<short>(); List<string> dataStrings = new List<string>(); /// Code types... /// 1000 == String up to 255 bytes /// 1001 == Application Name // Set Applicaiton Name dataTypes.Add(1001); dataStrings.Add(applicationName); // Set Application Data dataTypes.Add(1000); dataStrings.Add(xData.field1.ToString()); dataTypes.Add(1000); dataStrings.Add(xData.field2.ToString()); dataTypes.Add(1000); dataStrings.Add(xData.field3.ToString()); dataTypes.Add(1000); dataStrings.Add(xData.field4.ToString()); dataTypes.Add(1000); dataStrings.Add(xData.field5.ToString()); // ... etc. xDataType = dataTypes.ToArray(); xDataStrings = dataStrings.ToArray(); } The error I get is "Invalid argument data in SetXData method". The error code (if this helps anyone) is -2145320939. The main reason I'm posting is because the same code in a very old VB6 application works just fine. I'm stumped.

• C# Julian Date Parser

  - by Jake Pearson

  I have a cell in a spreadsheet that is a date object in Excel but becomes a double (something like 39820.0 for 1/7/2009) when it comes out of C1's xls class. I read this is a Julian date format. Can someone tell me how to parse it back into a DateTime in C#? Update: It looks like I might not have a Julian date, but instead the number of days since Dec 30, 1899.

• ASP.NET MVC 2.0 JsonRequestBehavior Global Setting

  - by beckelmw

  ASP.NET MVC 2.0 will now, by default, throw an exception when an action attempts to return JSON in response to a GET request. I know this can be overridden on a method by method basis by using JsonRequestBehavior.AllowGet, but is it possible to set on a controller or higher basis (possibly the web.config)? Update: Per Levi's comment, this is what I ended up using- protected override JsonResult Json(object data, string contentType, System.Text.Encoding contentEncoding) { return Json(data, contentType, JsonRequestBehavior.AllowGet); }

• NUnit.Framework.Assert.IsInstanceOfType() is obsolete

  - by Malice

  I'm currently reading the book Professional Enterprise .NET and I've noticed this warning in some of the example programs: 'NUnit.Framework.Assert.IsInstanceOfType(System.Type, object)' is obsolete Now I may have already answered my own question but, to fix this warning is it simply a case of replacing Assert.IsInstanceOfType() with Assert.IsInstanceOf()? For example this: Assert.IsInstanceOfType(typeof(ClassName), variableName); would become: Assert.IsInstanceOf(typeof(ClassName), variableName);

• Flex 4 - What makes a GC root?

  - by Michael Brewer-Davis

  What are the rules for something to be a GC root in Flash? I'm using the Flash Builder 4 profiler, and I'm finding odd things are labeled as GC roots in the object reference details (e.g., an Image control that is no longer in the display list, nor static).
