• Resharper function to fix naming convention issues

  - by Jan Jongboom

  A bunch of classes doesn't comply to our naming conventions for private variables. Resharper shows this as a warning, but wants me to fix all of them by hand. Is there some magic option to auto-fix these issues? 'Clean-up code' won't do anything with this. Same goes for converting properties with backing fields to automatic properties when possible: the hint is shown, but Resharper won't fix it automatically.

• Flex - Flash Builder Design View not showing embedded fonts correctly

  - by Crusader

  Tools: Air 2, Flex SDK 4.1, Flash Builder, Halo component set (NO Spark being used at all) Fonts work perfectly when running the appliction, but not in design view. This effectively makes design view WORTHLESS because it's impossible to properly position components or labels without knowing what the true size is (it changes depending on font...) ... CSS included in root component like so: <fx:Style source="style.css"/> CSS file: /* CSS file */ @namespace mx "library://ns.adobe.com/flex/mx"; global { font-family:Segoe; font-size:14; color:#FFFFFF; } mx|Application, mx|VBox, mx|HBox, mx|Canvas { font-family:Segoe; background-color:#660000; border-color:#222277; color:#FFFFFF; } mx|Button { font-family:Segoe; fill-colors:#660000, #660000, #660000, #660000; color:#FFFFFF; } .... Interestingly (or buggily?), when I try pasting the style tag into a subcomponent (lower than the top level container), I get a bunch of warnings in the subcomponent editor view stating that CSS type selectors are not supported in.. (all the components in the style sheet). Yet, they do work when the application is executed. Huh? This is how I'm embedding the fonts in the root level container: [Embed(source="/assets/segoepr.ttf", fontName="Segoe", mimeType="application/x-font-truetype", embedAsCFF='false')] public static const font:Class; [Embed(source="/assets/segoeprb.ttf", fontName="Segoe", mimeType="application/x-font-truetype", fontWeight="bold", embedAsCFF='false')] public static const font2:Class; So, is there a way to get embedded fonts to work in design view or what?

• Creating meaningful routes in wizard style ASP.NET MVC form

  - by R0MANARMY

  I apologize in advance for a long question, figured better have a bit more information than not enough. I'm working on an application with a fairly complex form (~100 fields on it). In order to make the UI a little more presentable the fields are organized into regions and split across multiple (~10) tabs (not unlike this, but each tab does a submit/redirect to next tab). This large input form can also be in one of 3 views (read only, editable, print friendly). The form represents a large domain object (let's call it Foo). I have a controller for said domain object (FooController). It makes sense to me to have the controller be responsible for all the CRUD related operations. Here are the problems I'm having trouble figuring out. Goals: I'd like to keep to conventions so that Foo/Create creates a new record Foo/Delete deletes a record Foo/Edit/{foo_id} takes you to the first tab of the form ...etc I'd like to be able to not repeat the data access code such that I can have Foo/Edit/{foo_id}/tab1 Foo/View/{foo_id}/tab1 Foo/Print/{foo_id}tab1 ...etc use the same data access code to get the data and just specify which view to use to render it. My current implementation has a massive FooController with Create, Delete, Tab1, Tab2, etc actions. Tab actions are split out into separate files for organization (using partial classes, which may or may not be abuse of partial classes). Problem I'm running into is how to organize my controller(s) and routes to make that happen. I have the default route {controller}/{action}/{id} Which handles goal 1 properly but doesn't quite play nice with goal 2. I tried to address goal 2 by defining extra routes like so: routes.MapRoute( "FooEdit", "Foo/Edit/{id}/{action}", new { controller = "Foo", action = "Tab1", mode = "Edit", id = (string)null } ); routes.MapRoute( "FooView", "Foo/View/{id}/{action}", new { controller = "Foo", action = "Tab1", mode = "View", id = (string)null } ); routes.MapRoute( "FooPrint", "Foo/Print/{id}/{action}", new { controller = "Foo", action = "Tab1", mode = "Print", id = (string)null } ); However defining these extra routes causes the Url.Action to generate routs like Foo/Edit/Create instead of Foo/Create. That leads me to believe I designed something very very wrong, but this is my first attempt an asp.net mvc project and I don't know any better. Any advice with this particular situation would be awesome, but feedback on design in similar projects is welcome.

• How to Disable/Enable WYSIWYG editor in Magento 1.4

  - by latvian

  Hi When entering code in CMS static block(possible page as well) and in this code there is empty DIV tags such us: <a href="javascript:hide1(),show2(),hide3()"><div class="dropoff_button"></div></a> The DIV tags will be gone next time you open the block to edit. it will look as this <a href="javascript:hide1(),show2(),hide3()"> </a> without the div tags ...and saving again it modifies your code. I think it something to do with the 'show/hide editor'. By default it goes into the WYSIWYG editor, so when updating static block i don't see any other solution than 1."hide the editor' by clicking 'show/hide editor' 2.delete the old code from the editor 3. get code that doesn't miss the DIVs 4. Merge new code with code in 3 in some other editing software than magento 5. paste result in the magento editor, 6. Save Is this bug? What is your solution? Can i turn of WYSIWYG editor?

• This property cannot be set after writing has started! on a C# WebRequest Object

  - by EBAGHAKI

  I want to reuse a WebRequest object so that cookies and session would be saved for later request to the server. Below is my code. If i use Post function twice on the second time at request.ContentLength = byteArray.Length; it will throw an exception This property cannot be set after writing has started! But as you can see dataStream.Close(); Should close the writing process! Anybody knows what's going on? static WebRequest request; public MainForm() { request = WebRequest.Create("http://localhost/admin/admin.php"); } static string Post(string url, string data) { request.Method = "POST"; byte[] byteArray = Encoding.UTF8.GetBytes(data); request.ContentType = "application/x-www-form-urlencoded"; request.ContentLength = byteArray.Length; Stream dataStream = request.GetRequestStream(); dataStream.Write(byteArray, 0, byteArray.Length); dataStream.Close(); WebResponse response = request.GetResponse(); Console.WriteLine(((HttpWebResponse)response).StatusDescription); dataStream = response.GetResponseStream(); StreamReader reader = new StreamReader(dataStream); string responseFromServer = reader.ReadToEnd(); Console.WriteLine(responseFromServer); reader.Close(); dataStream.Close(); response.Close(); request.Abort(); return responseFromServer; }

• How to avoid the base class member functions getting overridden by sub class in objective - c

  - by Manjunath

  Like in java: A final class cannot be subclassed. This is done for reasons of security and efficiency. Accordingly, many of the Java standard library classes are final, for example java.lang.System and java.lang.String. All methods in a final class are implicitly final. How can I achieve this behavior in objective-c?

• How to test UI interaction of Silverlight dialogs?

  - by Bernard Vander Beken

  I am using Silverlight 3.0 Unit Testing, version Silverlight Toolkit November 2009. Apart from unit tests, it allows to do UI interaction tests, typically using AutomationPeer subclasses (eg ButtonAutomationPeer to interact with a Button). Are there AutomationPeer classes to test the interaction with the following: OpenFileDialog SaveFileDialog MessageBox In unit tests it would be possible to stub these, but for integration and browser testing it would be great to have this testable.

• Stop All Started Services on App Close / Exit

  - by Rad The Mad

  Is it possible to stop all started services when the user hits the Home Button? I use: startService(new Intent(ClassName.this, ClassName2.class)); stopService(new Intent(ClassName.this, ClassName2.class)); This means I will have to somehow add the 'stopService()' for 7+ of my app classes I've researched this topic and I think there's 'onTerminate' but still not sure how this should be implemented. Any help or hints would be appreciated! Thanks!

• Make an ActiveX control work without a form?

  - by Earlz

  We are using Topaz Signature pads. They provide their APIs in the from of an ActiveX control which is to be put on a Winform control. Well, the way our project will work we do not want to have a form(at least not visible). We just want for the signature ActiveX control to get an image in the background. static AxSigPlus sig = new AxSIGPLUSLib.AxSigPlus(); public static void Begin() { ((System.ComponentModel.ISupportInitialize)(sig)).BeginInit(); sig.Name = "sig"; sig.Location = new System.Drawing.Point(0, 0); sig.Size = new System.Drawing.Size(0, 0); sig.Enabled = true; sig.TabletState = 1; //error here sig.SigCompressionMode = 0; } Ok so I get an error at the marked line. The exception is Exception of type 'System.Windows.Forms.AxHost+InvalidActiveXStateException' was thrown. What do I do to solve this problem? Would it just be easier to create a new hidden form and put the control on it so it's invisible?

• Sometimes Xcode appears to ignore target build settings?

  - by Derek Clarkson

  Hi all, I've created a iPhone static library project with two targets like this Project -- Library (Device) target -- Library (simulator) target The device target has the SDK set to the device so it produces an armv6/7 library and the simulator target is set to the simulator SDK so it produces an i386 library. The issue I'm having is that the SDK settings on the targets keep getting overridden by the XCode active target setting. i.e. if I build the device target, but the XCode window is showing the active SDK as being the simlulator, XCode will build a simulator library instead of a device library, ignoring the settings of the target. Although it will put it into the *-iphoneos/ directory in the build directories! I originally had the same issue with another static library project, and after a lot of playing around got everything to work correctly. i.e. The targets ignore the XCode active SDK because they have their own specifications of what to build. The problem is that I don't know what made it work in that project and I have not been able to reproduce the issue in it either. Does anyone have any ideas as to what is going on? ciao Derek

• EventDispatcher between an as and an fla?

  - by Christopher Richa

  Hi everyone. I am making a fighting game in Flash and while I have everything running, I am missing something: a victory/loss screen. Logically, I know how to do it: if character.hp < 0 { character.dead = true; dispatchevent("death", event) } My problem is that I have no idea as to how to code it. I know I will use two classes and my two .fla files (unless I am wrong). I have two .fla files that are in play here: the Menu.fla file and the Arena.fla file. Menu.fla contains the entire navigation of the game, options, character selection screens, etc. and when it is time for the player to engage in battle, it loads the Arena.fla file, which contains only the backgrounds (depending on the selected stage) and for now is set to a length of one frame only. For Arena.fla, the real action happens in my classes, but logically, I would only need HP.as and Character.as. In Character.as, I have declared the following variable: var isDead:Boolean = false; //is character dead? In HP.as, believe I should have the following: if(currentHp<0) { currentHp = 0; character.isDead = true; //declared as var `character:Object;` EventDispatcher.dispatchEventListener("playerDead", playerDead); } And finally, in Arena.fla, I want to be able to detect the above-mentioned eventlistener and simply move on to a second frame which will display a message in the style of "PLAYER ONE HAS WON" or "PLAYER ONE HAS LOST" with a button that will allow me to go back to the character selection screen. This is the first part in which I am stuck: how do I detect the dispatched event listener in my main .fla file? Secondly, if the player clicks on the "CONTINUE" button, which displays regardless if the player has won or lost, how can my Menu.fla (which loads the Arena.swf) detect this click event, unload the game, and go back to the character selection screen? Thank you in advance for helping me out. I realize this is a lot of text but it's the most descriptive I can be. If you have any questions or need any clarification concerning my question, feel free to speak up. -Christopher

• Apache rewrite rules redux

  - by AlexanderJohannesen

  I've got a REST framework that when plopped into any directory should Just Work(TM), and it seems to work fine when I've got projects in subdirectories, but not if it's in root. So, given a few example directories; / /project1 /bingo/project2 /hoopla/doopla/minor/project3 All of these works fine, except I'm getting "funnies"* when the project runs in the root directory (bit hard to explain, I suppose, but the second level rewrites are not working properly). Here's my attempt at a generic .htaccess file: RewriteEngine On RewriteRule ^static/ - [L] RewriteCond %{REQUEST_URI} ^$ RewriteRule .* ./ [R,L] RewriteRule ^index.php - [L] RewriteRule (.*) index.php?q=$1 [QSA,PT] (And yes, all projects have a subdirectory ./static which is ignored by rewrites) What I'm trying to achieve is a set of rewrite rules that work for most cases (which is, again, plonking the project in a directory the webserver serves). I'm not a rewrite rules wiz by a long shot, and any good advice and gotchas would be appreciated (and yes, I've gone through too many introductory articles. I need some serious juice.) More info on the funnies; my webserver has docroot in one spot (under /usr/share/apache2/default-site/), but a set of rules that says that /projects is pulled in from somewhere else that's not a subdirectory of docroot (/home/user/Projects/). When I go there, I get a list of /projects subdirectories, and if one of those subdirectories gets called (restmapp) with the proposed rewrite rules, I get ; The requested URL /home/user/Projects/restmapp/index.php was not found on this server.

• When to use Python special methods?

  I know that classes can implement various special methods, such as __iter__, __setitem__, __len__, __setattr__, and many others. But when should I use them? Can anyone describe typical scenarios when I would want to implement them and they would simplify programming in Python? Thanks, Boda Cydo.

• Producing Mini Dumps for _caught_ SEH exceptions in mixed code DLL

  - by Assaf Lavie

  I'm trying to use code similar to clrdump to create mini dumps in my managed process. This managed process invokes C++/CLI code which invokes some native C++ static lib code, wherein SEH exceptions may be thrown (e.g. the occasional access violation). C# WinForms -> C++/CLI DLL -> Static C++ Lib -> ACCESS VIOLATION Our policy is to produce mini dumps for all SEH exceptions (caught & uncaught) and then translate them to C++ exceptions to be handled by application code. This works for purely native processes just fine; but when the application is a C# application - not so much. The only way I see to produce dumps from SEH exceptions in a C# process is to not catch them - and then, as unhandled exceptions, use the Application.ThreadException handler to create a mini dump. The alternative is to let the CLR translate the SEH exception into a .Net exception and catch it (e.g. System.AccessViolationException) - but that would mean no dump is created, and information is lost (stack trace information in Exception isn't as rich as the mini dump). So how can I handle SEH exceptions by both creating a minidump and translating the exception into a .Net exception so that my application may try to recover?

• InvalidCastException in DataGridView

  - by Max Yaffe

  (Using VS 2010 Beta 2 - .Net 4.0 B2 Rel) I have a class, MyTable, derived from BindingList where S is a struct. S is made up of several other structs, for example: public class MyTable<S>:BindingList<S> where S: struct { ... } public struct MyStruct { public MyReal r1; public MyReal r2; public MyReal R1 {get{...} set{...}} public MyReal R2 {get{...} set{...}} ... } public struct MyReal { private Double d; private void InitFromString(string) {this.d = ...;} public MyReal(Double d) { this.d = d;} public MyReal(string val) { this.d = default(Double); InitFromString(val);} public override string ToString() { return this.real.ToString();} public static explicit operator MyReal(string s) { return new MyReal(s);} public static implicit operator String(MyReal r) { return r.ToString();} ... } OK, I use the MyTable as a binding source for a DataGridView. I can load the data grid easily using InitFromString on individual fields in MyStruct. The problem comes when I try to edit a value in a cell of the DataGridView. Going to the first row, first column, I change the value of the existing number. It gives an exception blizzard, the first line of which says: System.FormatException: Invalid cast from 'System.String' to 'MyReal' I've looked at the casting discussions and reference books but don't see any obvious problems. Any ideas?

• CustomRenderer for AutoComplete using google closure library

  I'm looking to use one of the AutoComplete subclasses(Rich,Remote,RichRemote) and I'd like to use a CustomRenderer, however I don't see instructions for this and reading the documentation/source it appears that the Remote subclass is instantiated with a renderer of "var renderer = new goog.ui.AutoComplete.Renderer();" leaving me no option to change it while instantiating. Is there a setRenderer method on the AutoComplete base class similar to that on the goog.ui.Controls classes? Thanks, Paul
