• Strange Play Framework 2.2 exceptions after trying to add MySQL / slick

  - by Mike Cialowicz

  I'm working on a Play 2.2 application, and things have gone a bit south on me since I've tried adding my DB layer. Below are my build.sbt dependencies. As you can see I use mysql-connector-java and play-slick: libraryDependencies ++= Seq( jdbc, anorm, cache, "joda-time" % "joda-time" % "2.3", "mysql" % "mysql-connector-java" % "5.1.26", "com.typesafe.play" %% "play-slick" % "0.5.0.8", "com.aetrion.flickr" % "flickrapi" % "1.1" ) My application.conf has some similarly simple DB stuff in it: db.default.url="jdbc:mysql://localhost/myDb" db.default.driver="com.mysql.jdbc.Driver" db.default.user="root" db.default.pass="" This is what it looks like when my Play server starts: [info] play - Listening for HTTP on /0:0:0:0:0:0:0:0:9000 (Server started, use Ctrl+D to stop and go back to the console...) [info] Compiling 1 Scala source to C:\bbq\cats\in\space [info] play - database [default] connected at jdbc:mysql://localhost/myDb [info] play - Application started (Dev) So, it appears that Play can connect to the MySQL DB just fine (I think). However, I get this exception when I make any request to my server: [error] p.nettyException - Exception caught in Netty java.lang.NoSuchMethodError: akka.actor.ActorSystem.dispatcher()Lscala/concurren t/ExecutionContext; at play.core.Invoker$.<init>(Invoker.scala:24) ~[play_2.10.jar:2.2.0] at play.core.Invoker$.<clinit>(Invoker.scala) ~[play_2.10.jar:2.2.0] at play.api.libs.concurrent.Execution$Implicits$.defaultContext$lzycompu te(Execution.scala:7) ~[play_2.10.jar:2.2.0] at play.api.libs.concurrent.Execution$Implicits$.defaultContext(Executio n.scala:6) ~[play_2.10.jar:2.2.0] at play.api.libs.concurrent.Execution$.<init>(Execution.scala:10) ~[play _2.10.jar:2.2.0] at play.api.libs.concurrent.Execution$.<clinit>(Execution.scala) ~[play_ 2.10.jar:2.2.0] The odd thing is that the 2nd request (to the exact same URL, same controller, no changes) comes back with a different error: [error] p.nettyException - Exception caught in Netty java.lang.NoClassDefFoundError: Could not initialize class play.api.libs.concurr ent.Execution$ at play.core.server.netty.PlayDefaultUpstreamHandler.handleAction$1(Play DefaultUpstreamHandler.scala:194) ~[play_2.10.jar:2.2.0] at play.core.server.netty.PlayDefaultUpstreamHandler.messageReceived(Pla yDefaultUpstreamHandler.scala:169) ~[play_2.10.jar:2.2.0] at com.typesafe.netty.http.pipelining.HttpPipeliningHandler.messageRecei ved(HttpPipeliningHandler.java:62) ~[netty-http-pipelining.jar:na] at org.jboss.netty.handler.codec.http.HttpContentDecoder.messageReceived (HttpContentDecoder.java:108) ~[netty-3.6.5.Final.jar:na] at org.jboss.netty.channel.Channels.fireMessageReceived(Channels.java:29 6) ~[netty-3.6.5.Final.jar:na] at org.jboss.netty.handler.codec.frame.FrameDecoder.unfoldAndFireMessage Received(FrameDecoder.java:459) ~[netty-3.6.5.Final.jar:na] The URL / controller that I'm requesting just renders a static web page and doesn't do anything of any significance. It was working just fine before I started adding my DB layer. I'm rather stuck. Any help would be greatly appreciated, thanks. I'm using Scala 2.10.2, Play 2.2.0, and MySQL Server 5.6.14.0 (community edition).

• ASP.NET MVC 2 JQuery POST not displaying the model state errors

  - by Oshan

  Hello, I have been using asp.net mvc for a bit (but I'm still a beginer). I want to have the ability to update two views as a result of a jquery postback. Basically I have a list and a details view. The details view is presented using a jquery popup (using jquery-UI popup). I only want to update the list if the details save is successful (i.e. there are no validation errors on the details view). However, if there are any validation errros in the details view, I want to update the details view so that the user sees the validation errors. so I thought in my controller, I return a JsonResult instead of a View. [HttpPost] public ActionResult SavePersonInfo(Person p) { if(ModelState.Valid) { return View("PersonList"); } return Json({Error = true, View = PartialView("PersonDetails", p)}); } As you can see if there are no errors I return the person list view, but if there are any validation errors, I have return the details view. The reason that I'm returning a JsonResult is I need to tell my view there is an error so that the view (jquery) knows which section to update (as in whether to update the person list 'div' or the popup dialog 'div'). So, in my view, the jquery is as follows (please assume that there is a form for entering in the person details and "SubmitPersonForm();" function is called upon clicking on the "Save" button): <script type="text/javascript> $('#btnSave').click(function (event) { onBegin(); $.ajax( { type: "POST", url: "/Person/Save", data: $('form').serialize(), success: function (result) { if(result.Error) { $('#dvDetails').html($(result).View)); } else { $('#dvPersonList').html($result); } } }); }); </script> So the problem that I have now, is that when there is a validation error, I do see the correct, 'div' being updated, but I lose the asp.net mvc validation messages. I do not see any validation errors in red, as if ASP.NET MVC is completely ignored them. However, my ModelState does have those errros, just not displayed in the details view. I do have valication summary and Html.ValidationFor(m = ...) statements put in my details view. Could someone tell me why I'm not seeing the validation errors? although I'm using a JSonResult, I do use the right property which is a valid view when I render the 'dvDetails'. Am I doing something that I'm not suppose to in asp.net mvc? Btw I'm using asp.net mvc2 RC with Visual Studio 2010 RC. Thank you.

• Attaching .swf assets to Flex3 by calling getDefinitionByName()

  - by Alexander Farber

  Hello! Does anybody please know, how could you attach symbols from an .swf file in the Actionscript part of your Flex3 file? I've prepared a simple test case demonstrating my problem. Everything works (there are icons at the 4 buttons, there is a red circle) - except the getDefinitionByName() part. My target is to attach a symbol from library "dynamically" - i.e. depending at the value of the suit variable at the runtime. Thank you, Alex Symbols.as: package { public class Symbols { [Embed('../assets/symbols.swf', symbol='spades')] public static const SPADES:Class; [Embed('../assets/symbols.swf', symbol='clubs')] public static const CLUBS:Class; [Embed('../assets/symbols.swf', symbol='diamonds')] public static const DIAMONDS:Class; [Embed('../assets/symbols.swf', symbol='hearts')] public static const HEARTS:Class; } } TestCase.mxml: <?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" creationComplete="onCreationComplete();"> <mx:Script> <![CDATA[ private function onCreationComplete():void { var sprite:Sprite = new Sprite(); var g:Graphics = sprite.graphics; g.lineStyle(1, 0xFF0000); g.beginFill(0xFF0000); g.drawCircle(100, 100, 20); g.endFill(); spriteHolder.addChild(sprite); // XXX stuff below not working, can it be fixed? var suit:String = "SPADES"; var mc:MovieClip = new (getDefinitionByName("Symbols.SPADES") as Class); spriteHolder.addChild(mc); } ]]> </mx:Script> <mx:VBox width="100%"> <mx:Button label="1" icon="{Symbols.SPADES}" /> <mx:Button label="2" icon="{Symbols.CLUBS}" /> <mx:Button label="3" icon="{Symbols.DIAMONDS}" /> <mx:Button label="4" icon="{Symbols.HEARTS}" /> <mx:UIComponent id="spriteHolder" width="200" height="200"/> </mx:VBox> </mx:Application>

• Best programming aids for a quadriplegic programmer

  - by Peter Rowell

  Before you jump to conclusions, yes, this is programming related. It covers a situation that comes under the heading of, "There, but for the grace of God, go you or I." This is brand new territory for me so I'm asking for some serious help here. A young man, Honza Ripa, in a nearby town did the classic Dumb Thing two weeks after graduating from High School -- he dove into shallow water in the Russian River and had a C-4/C-5 break, sometimes called a Swimming Pool break. In a matter of seconds he went from an exceptional golfer and wrestler to a quadriplegic. (Read the story ... all of us should have been so lucky as to have a girlfriend like Brianna.) That was 10 months ago and he has regained only tiny amounts of control of his right index finger and a couple of other hand/foot motions, none of them fine-grained. His total control of his computer (currently running Win7, but we can change that as needed) is via voice command. Honza's not dumb. He had a 3.7 GPA with AP math and physics. The Problems: Since all of his input is via voice command, he is concerned that the predominance of special characters in programming will require vast amount of verbose commands. Does anyone know of any well done voice input system specifically designed for programmers? I'm thinking about something that might be modal--e.g. you say "Python input" and it goes into a macro mode for doing class definitions, etc. Given all of the RSI in programmer-land there's got to be something out there. What OS(es) does it run on? I am planning on teaching him Python, which is my preferred language for programming and teaching. Are there any applications / whatevers that are written in Python and would be a particularly good match for engaging him mentally while supporting his disability? One of his expressed interests is in stock investing, but that not might be a good starting point for a brand-new programmer. There are a lot of environments (Flash, JavaScript, etc) that are not particularly friendly to people with accessibility challenges. I vaguely remember (but cannot find) a research project that basically created an overlay system on top of a screen environment and then allowed macro command construction on top of the screen image. If we can get/train this system, we may be able to remove many hurdles to using the net. I am particularly interested in finding open source Python-based robotics and robotic prostheses projects so that he can simultaneously learn advanced programming concepts while learning to solve some of his own immediate problems. I've done a ton of googling on this, but I know there things I'm missing. I'm asking the SO community to step up to the plate here. I know this group has the answers, so let me hear them! Overwhelm me with the opportunities that any of us might have/need to still program after such a life-changing event.

• Fluid CSS: floating column with max-width and overflow

  - by Ates Goral

  I'm using a fluid layout in the new theme that I'm working on for my blog. I often blog about code and include <pre> blocks within the posts. The float: left column for the content area has a max-width so that the column stops at a certain maximum width and can also be shrunk: +----------+ +------+ | text | | text | | | | | | | | | | | | | | | | | | | | | +----------+ +------+ max shrunk What I want is for the <pre> elements to be wider than the text column so that I can fit 80-character-wrapped code without horizontal scroll bars. But I want the <pre> elements to overflow from the content area, without affecting its fluidity: +----------+ +------+ | text | | text | | | | | +----------+--+ +------+------+ | code | | code | +----------+--+ +------+------+ | | | | +----------+ +------+ max shrunk But, max-width stops being fluid once I insert the overhanging <pre> in there: the width of the column remains at the specified max-width even when I shrink the browser beyond that width. I've reproduced the issue with this bare-minimum scenario: <div style="float: left; max-width: 460px; border: 1px solid red"> <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit</p> <pre style="max-width: 700px; border: 1px solid blue"> function foo() { // Lorem ipsum dolor sit amet, consectetur adipisicing elit } </pre> <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit</p> </div> I noticed that doing either of the following brings back the fluidity: Remove the <pre> (doh...) Remove the float: left The workaround I'm currently using is to insert the <pre> elements into "breaks" in the post column, so that the widths of the post segments and the <pre> segments are managed mutually exclusively: +----------+ +------+ | text | | text | +----------+ +------+ +-------------+ +-------------+ | code | | code | +-------------+ +-------------+ +----------+ +------+ +----------+ +------+ max shrunk But this forces me to insert additional closing and opening <div> elements into the post markup which I'd rather keep semantically pristine. Admittedly, I don't have a full grasp of how the box model works with floats with overflowing content, so I don't understand why the combination of float: left on the container and the <pre> inside it cripple the max-width of the container. I'm observing the same problem on Firefox/Chrome/Safari/Opera. IE6 (the crazy one) seems happy all the time. This also doesn't seem dependent on quirks/standards mode. Update I've done further testing to observe that max-width seems to get ignored when the element has a float: left. I glanced at the W3C box model chapter but couldn't immediately see an explicit mention of this behaviour. Any pointers?

• CGContextDrawPDFPage doesn't seem to persist in CGContext

  - by erichf

  I am trying to access the pixels of a CGContext written to with a PDF, but the bitmap buffer doesn't seem to update. Any help would be appreciated: //Get the reference to our current page pageRef = CGPDFDocumentGetPage(docRef, iCurrentPage); //Start with a media crop, but see if we can shrink to smaller crop CGRect pdfRect1 = CGRectIntegral(CGPDFPageGetBoxRect(pageRef, kCGPDFMediaBox)); CGRect r1 = CGRectIntegral(CGPDFPageGetBoxRect(pageRef, kCGPDFCropBox)); if (!CGRectIsEmpty(r1)) pdfRect1 = r1; int wide = pdfRect1.size.width + pdfRect1.origin.x; int high = pdfRect1.size.height + pdfRect1.origin.y; CGContextRef ctxBuffer = NULL; CGColorSpaceRef colorSpace; UInt8* bitmapData; int bitmapByteCount; int bitmapBytesPerRow; bitmapBytesPerRow = (wide * 4); bitmapByteCount = (bitmapBytesPerRow * high); colorSpace = CGColorSpaceCreateDeviceRGB(); bitmapData = malloc( bitmapByteCount ); if (bitmapData == NULL) { DebugLog (@"Memory not allocated!"); return; } ctxBuffer = CGBitmapContextCreate (bitmapData, wide, high, 8, // bits per component bitmapBytesPerRow, colorSpace, kCGImageAlphaPremultipliedLast | kCGBitmapByteOrder32Big); // if (ctxBuffer== NULL) { free (bitmapData); DebugLog (@"Context not created!"); return; } CGColorSpaceRelease( colorSpace ); //White out the current context CGContextSetRGBFillColor(ctxBuffer, 1.0, 1.0, 1.0, 1.0); CGContextFillRect(ctxBuffer, CGContextGetClipBoundingBox(ctxBuffer)); CGContextDrawPDFPage(ctxBuffer, pageRef); //!!!This displays just fine to the context passed in from - (void)drawLayer:(CALayer *)layer inContext:(CGContextRef)ctx.

• Server side Xforms form validation and integration into ASP.NET

  - by Nigel

  I have recently been investigating methods of creating web-based forms for an ASP.NET web application that can be edited and managed at runtime. For example an administrator might wish to add a new validation rule or a new set of fields. The holy grail would provide a means of specifying a form along with (potentially very complex) arbitrary validation rules, and allocation of data sources for each field. The specification would then be used to update the deployed form in the web application which would then validate submissions both on the client side and on the server side. My investigations led me to Xforms and a number of technologies that support it. One solution appears to be IBM Lotus Forms, but this requires a very large investment in terms of infrastructure, which makes it infeasible, although the forms designer may be useful as a stand-alone tool for creating the forms. I have also discounted browser plug-ins as the form must be publicly visible and cross-browser compliant. I have noticed that there are numerous javascript libraries that provide client side implementations given an Xforms schema. These would provide a partial solution but server side validation is still a requirement. Another option seems to involve the use of server side solutions such as the Java application Orbeon. Orbeon provides a tool for specifying the forms (although not as rich as Lotus Forms Designer), but the most interesting point is that it can translate an XForms schema into an XHTML form complete with validation. The fact that it is written in Java is not a big problem if it is possible to integrate with the existing ASP.NET application. So my question is whether anyone has done this before. It sounds like a problem that should have been solved but is inherently very complex. It seems possible to use an off-the-shelf tool to design the form and export it to an Xforms schema and xhtml form, and it seems possible to take that xforms schema and form and publish it using a client side library. What seems to be difficult is providing a means of validating the form submission on the server side and integrating the process nicely with .NET (although it seems the .NET community doesn't involve themselves with XForms; please correct me if I'm wrong on this count). I would be more than happy if a product provided something simple like a web service that could validate a submission against a schema. Maybe Orbeon does this but I'd be grateful if somebody in the know could point me in the right direction before I research it further. Many thanks.

• Which functions in the C standard library commonly encourage bad practice?

  - by Ninefingers

  Hello all, This is inspired by this question and the comments on one particular answer in that I learnt that strncpy is not a very safe string handling function in C and that it pads zeros, until it reaches n, something I was unaware of. Specifically, to quote R.. strncpy does not null-terminate, and does null-pad the whole remainder of the destination buffer, which is a huge waste of time. You can work around the former by adding your own null padding, but not the latter. It was never intended for use as a "safe string handling" function, but for working with fixed-size fields in Unix directory tables and database files. snprintf(dest, n, "%s", src) is the only correct "safe strcpy" in standard C, but it's likely to be a lot slower. By the way, truncation in itself can be a major bug and in some cases might lead to privilege elevation or DoS, so throwing "safe" string functions that truncate their output at a problem is not a way to make it "safe" or "secure". Instead, you should ensure that the destination buffer is the right size and simply use strcpy (or better yet, memcpy if you already know the source string length). And from Jonathan Leffler Note that strncat() is even more confusing in its interface than strncpy() - what exactly is that length argument, again? It isn't what you'd expect based on what you supply strncpy() etc - so it is more error prone even than strncpy(). For copying strings around, I'm increasingly of the opinion that there is a strong argument that you only need memmove() because you always know all the sizes ahead of time and make sure there's enough space ahead of time. Use memmove() in preference to any of strcpy(), strcat(), strncpy(), strncat(), memcpy(). So, I'm clearly a little rusty on the C standard library. Therefore, I'd like to pose the question: What C standard library functions are used inappropriately/in ways that may cause/lead to security problems/code defects/inefficiencies? In the interests of objectivity, I have a number of criteria for an answer: Please, if you can, cite design reasons behind the function in question i.e. its intended purpose. Please highlight the misuse to which the code is currently put. Please state why that misuse may lead towards a problem. I know that should be obvious but it prevents soft answers. Please avoid: Debates over naming conventions of functions (except where this unequivocably causes confusion). "I prefer x over y" - preference is ok, we all have them but I'm interested in actual unexpected side effects and how to guard against them. As this is likely to be considered subjective and has no definite answer I'm flagging for community wiki straight away. I am also working as per C99.

• Using MongoDB with Ruby On Rails and the Mongomapper plugin

  - by Micke

  Hello, i am currently trying to learn Ruby On Rails as i am a long-time PHP developer so i am building my own community like page. I have came pritty far and have made the user models and suchs using MySQL. But then i heard of MongoDB and looked in to it a little bit more and i find it kinda nice. So i have set it up and i am using mongomapper for the connection between rails and MongoDB. And i am now using it for the News page on the site. I also have a profile page for every User which includes their own guestbook so other users can come to their profile and write a little message to them. My thought now is to change the User models from using MySQL to start using MongoDB. I can start by showing how the models for each User is set up. The user model: class User < ActiveRecord::Base has_one :guestbook, :class_name => "User::Guestbook" The Guestbook model model: class User::Guestbook < ActiveRecord::Base belongs_to :user has_many :posts, :class_name => "User::Guestbook::Posts", :foreign_key => "user_id" And then the Guestbook posts model: class User::Guestbook::Posts < ActiveRecord::Base belongs_to :guestbook, :class_name => "User::Guestbook" I have divided it like this for my own convenience but now when i am going to try to migrate to MongoDB i dont know how to make the tables. I would like to have one table for each user and in that table a "column" for all the guestbook entries since MongoDB can have a EmbeddedDocument. I would like to do this so i just have one Table for each user and not like now when i have three tables just to be able to have a guestbook. So my thought is to have it like this: The user model: class User include MongoMapper::Document one :guestbook, :class_name => "User::Guestbook" The Guestbook model model: class User::Guestbook include MongoMapper::EmbeddedDocument belongs_to :user many :posts, :class_name => "User::Guestbook::Posts", :foreign_key => "user_id" And then the Guestbook posts model: class User::Guestbook::Posts include MongoMapper::EmbeddedDocument belongs_to :guestbook, :class_name => "User::Guestbook" But then i can think of one problem.. That when i just want to fetch the user information like a nickname and a birthdate then it will have to fetch all the users guestbook posts. And if each user has like a thousand posts in the guestbook it will get really much to fetch for the system. Or am i wrong? Do you think i should do it any other way? Thanks in advance and sorry if i am hard to understand but i am not so educated in the english language :)

• Firebug not breaking on errors

  - by stormdrain

  Hi. I reinstalled Firefox today, because... whatever. I reinstalled firebug, therefully, and now when I try to use it, it's all different. I believe it is the same version I had before. In fact, I even went digging through my trash and replaced the new firebug with the one I removed with the old Firefox. They ended up being the same version (1.5.3). My issue is, when I have an error in my script somewhere, it used to be that if on the script pane of firebug, the script would break on the error, and the script page would go to the offending line, highlighted, and all was right with the world. Now, it logs the error in the console, and that's it. I've spent the better part of the last hour trying to convince myself this isn't worth an ulcer; I am losing the battle, though. I've searched Google, put ads on Craigslist, even thought about becoming a cop. There were some examples on the Firebug dox, but none of them helped. A bunch of old references to a mysterious (break on all errors) option; an option which I think I might have set by accident--there is a little red circle-slash on my pause button (that's what she said), but there the script continues, all on its own. There was a guide somewhere on the firebug pages that spoke of setting the breakpoint next to the error in the console. I, however, don't have this option for some reason. The line of code is there in the console, but no breakpoint button next to it. This, however, would not be ideal even if it worked. I liked it when I could have the script page open, and if there were errors it would jump to that line. I could try to fix it, and re-load the page. If that line was fixed, GREAT, on to the next error on the page -- which would be highlighted and ready. I would like to offer a solicitation of help. Help.

• Stretching width correctly to 100% of an inline-block element in IE6 and IE7

  - by Simon Lieschke

  I have the following markup, where I am attempting to get the right hand side of the second table to align with the right hand side of the heading above it. This works in IE8, Firefox and Chrome, but in IE6/7 the table is incorrectly stretched to fill the width of the page. I'm using the Trip Switch hasLayout trigger to apply inline-block in IE6/7. Does anyone know how (or even if) I can get the table only to fill the natural width of the wrapper element displayed with inline-block in IE6/7? You can see the code running live at http://jsbin.com/uyuva. <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <title>Test</title> <style> .wrapper { display: inline-block; border: 1px solid green; } /* display: inline-block triggers the wrapper element to have layout for IE 6/7. The trip switch then provides the inline component of the display behaviour. See http://www.brunildo.org/test/InlineBlockLayout.html for more details. */ .wrapper { *display: inline; } table { border: 1px solid red; } </style> </head> <body> <h1>No width on table:</h1> <div class="wrapper"> <h2>The right hand side of the table doesn't stretch to the end of this heading</h2> <table><tr><td>foo</td></tr></table> </div> text <h1>Width on table:</h1> <div class="wrapper"> <h2>The right hand side of the table should stretch to the end of this heading</h2> <table style="width: 100%"><tr><td>foo</td></tr></table> </div> text </body> </html>

• pyQt4: QWidget subclass not responding to new setStyleSheet() background colour

  - by Ronny

  I am having an issue with PyQt4. I want to create a new widget within a window, and I want this widget to have a custom color. When i create a subclass of the QWidget class, and instantiate it, I am not able to change its background color through the setStyleSheet() function. When I instantiate a new QWidget object, I have no problems in changing its background color. But i dont want an ordinary QWidget object.I want to create my own subclass of QWidget. When i create a subclass of a QPushButton, I am also able to change its background color using the setStyleSheet() function. There are no error messages or warnings in the console window, it just refuses to work properly without any indication as to why. So what i would like to know is why is it that i can change the background color of a widget if i simply create a QWidget object, or a subclass of QPushButton, but not when i create a subclass of QWidget. And how can i therefore change the background color of an object that is a subclass of QWidget? Is it maybe something specific to the version of python or PyQt that i am using? Is it a bug in the library? or some flaw in the way that i am writing my code? I am using python 2.6.4 and PyQt4 Below is an example of the code that leads me to trouble. There are three widgets within the window one below the other. The parent widget is set with background color of green. The top widget is set to red, the middle one, is the subclass of QWidget, which should be blue, but it appears invisible because it takes on the color of the parent window for some reason. and the bottom widget is a subclass of QPushButton and is white. import sys from PyQt4 import QtGui, QtCore ################################################################################ #--------------------------------------------------------- CUSTOM WIDGET CLASS 1 class CustomWidget(QtGui.QWidget): def __init__(self, parent): QtGui.QWidget.__init__(self, parent) # some custom properties and functions will follow ################################################################################ #--------------------------------------------------------- CUSTOM WIDGET CLASS 2 class CustomWidget2(QtGui.QPushButton): def __init__(self, parent): QtGui.QPushButton.__init__(self, parent) # some custom properties and functions will follow ################################################################################ #----------------------------------------------------------- PARENT WIDGET CLASS class Parent(QtGui.QWidget): def __init__(self, parent=None): #---------------------------------------------------------- SETUP WINDOW QtGui.QWidget.__init__(self, parent) self.resize(500, 340) self.setStyleSheet("QWidget {background-color: #00FF00}") #-------------------------------------------------- SETUP DEFAULT WIDGET wid1 = QtGui.QWidget(self) wid1.setGeometry(10, 10, 480, 100) wid1.setStyleSheet("QWidget {background-color: #FF0000 }") #------------------------------------------------- SETUP CUSTOM WIDGET 1 wid2 = CustomWidget(self) wid2.setGeometry(10, 120, 480, 100) wid2.setStyleSheet("QWidget {background-color: #0000FF }") for i in dir(wid2): print i #------------------------------------------------- SETUP CUSTOM WIDGET 2 wid3 = CustomWidget2(self) wid3.setGeometry(10, 230, 480, 100) wid3.setStyleSheet("QWidget {background-color: #FFFFFF }") ################################################################################ #-------------------------------------------------------------------------- MAIN app = QtGui.QApplication(sys.argv) win = Parent() win.show() app.exec_()

  - by Alessandro Di Lello

  Hi All, i'm developing a WCF Webservice and consuming it within a mvc2 application. My problem is that i'm using FaultContracts on my methods with a custom FaultDetail and i'm throwing manyally the faultexception but when the client receive the exception , it receives a normal SoapException instead of my FaultException that i throwed from the service side. Here is some code: Custom Fault Detail Class: [DataContract] public class MyFaultDetails { [DataMember] public string Message { get; set; } } Operation on service contract: [OperationContract] [FaultContract(typeof(MyFaultDetails))] void ThrowException(); Implementation: public void ThrowException() { var details = new MyFaultDetails { Message = "Exception Test" }; throw new FaultException<MyFaultDetails >(details , new FaultReason(details .Message), new FaultCode("MyFault")); } Client side: try { // Obv proxy init etc.. service.ThrowException(); } catch (FaultException<MyFaultDetails> ex) { // stuff } catch (Exception ex) { // stuff } What i expect is to catch the FaultException , instead that catch is skipped and the next catch is taken with an exception of type SoapException. Am i missing something ? i red a lot of threads about using faultcontracts within wcf and what i did seems to be good. I had a look at the wsdl and xsd generated and they look fine. here's a snippet regarding this method: <wsdl:operation name="ThrowException"> <wsdl:input wsaw:Action="http://tempuri.org/IAnyJobService/ThrowException" message="tns:IAnyJobService_ThrowException_InputMessage" /> <wsdl:output wsaw:Action="http://tempuri.org/IAnyJobService/ThrowExceptionResponse" message="tns:IAnyJobService_ThrowException_OutputMessage" /> <wsdl:fault wsaw:Action="http://tempuri.org/IAnyJobService/ThrowExceptionAnyJobServiceFaultExceptionFault" name="AnyJobServiceFaultExceptionFault" message="tns:IAnyJobService_ThrowException_AnyJobServiceFaultExceptionFault_FaultMessage" /> </wsdl:operation> <wsdl:operation name="ThrowException"> <soap:operation soapAction="http://tempuri.org/IAnyJobService/ThrowException" style="document" /> <wsdl:input> <soap:body use="literal" /> </wsdl:input> <wsdl:output> <soap:body use="literal" /> </wsdl:output> <wsdl:fault name="AnyJobServiceFaultExceptionFault"> <soap:fault use="literal" name="AnyJobServiceFaultExceptionFault" namespace="" /> </wsdl:fault> </wsdl:operation> Any help ? Thanks in advance Regards Alessandro

• Best practice to handle Parent Form Child Form relation using Presentation Model

  - by Rajarshi

  According to Presentation Model notes by Martin Fowler and also on MSDN documentation about Presentation Model, it is explained that the Presentation Model Class should be unaware of the UI class and similarly Business Model Class should be unaware of the Presentation Model class. The UI should databind extensively to the Presentation Model, the Presentation Model in turn will co-ordinate with one or more Domain/Business Model objects to get the job done. The Presentation Model basically presents the Domain Model data in a way to facilitate maximum data binding in UI, allowing the UI take as less decisions as possible and thus increase testability of Presentation behaviours. This also makes the presentation model class generic, i.e. agnostic of any particular UI technology. Now, consider there is a List form (say CustomerList) and there is another Root form (say Customer) and there is a Use Case of allowing to Edit a Customer from the CustomerList form on a button click. For simplicity of discussion, consider that some actions took place when Customer List is opened from menu (i.e. Customer menu clicked) and the Customer List has been shown from the Menu click event. Now as per the above Use Case, I need to open the Customer Root UI (single Customer) from the Customer List. How do I do that? Build necessary objects (BusinessModel, PresentationModel, UI) in click event of Edit button and call CustomerEdit UI from there? Build the CustomerEdit UI from Presentation Model Class and show UI from presentation model? this can be done in any of the two ways below - a. Create objects in the following sequence DomainModel-PresentationModel-UIForm b. Use Unity.Resolve(); Either ways, Presentation Model is violated as the P model now has to the refer the concrete UI assembly, where CustomerEdit is located. Also the P Model has to refer and use a WinForm directly making it less UI technology agnostic. Even though the violations are in theory and can be ignored, I would still seek the community's opinion about whether I am going wrong direction. Please suggest if there's a better way to call the Child Form from the List (Parent) Form. Rajarshi

• DataTrigger only works on first TabItem in TabControl

  - by JustusJonas

  Hi! It seems like a bug in WPF, but maybe someone has an answers to this. I have a DataTrigger for an editable ComboBox. It works on the first TabItem of my TabControl, but not on the second. If you switch the first with the second TabItem, the "second" will work. The same effect happens when you give the style exactly to the ComboBox (ComboBox.Stye ...). <Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" x:Class="MainWindow" x:Name="Window" Title="MainWindow" Width="640" Height="480"> <Window.Resources> <Style TargetType="{x:Type ComboBox}"> <Setter Property="Height" Value="25" /> <Setter Property="Width" Value="125" /> <Style.Triggers> <DataTrigger Binding="{Binding ElementName=PART_EditableTextBox, Path=IsFocused}" Value="True"> <Setter Property="BitmapEffect"> <Setter.Value> <OuterGlowBitmapEffect GlowColor="Red" GlowSize="5" /> </Setter.Value> </Setter> </DataTrigger> </Style.Triggers> </Style> </Window.Resources> <Grid x:Name="LayoutRoot"> <TabControl> <TabItem Header="TabItem1"> <Grid> <ComboBox IsEditable="True"/> </Grid> </TabItem> <TabItem Header="TabItem2"> <Grid> <ComboBox IsEditable="True"/> </Grid> </TabItem> </TabControl> </Grid>

• CSS: Aligning problem with rounded corners in IE 6/7 but ok in IE8/ Firefox etc

  - by mark smith

  Hi there, can anyone help? I have a problem aligning rounded corners in IE6/7. Basically everything seems to work in Firefox / IE8 but in IE6/7 the left / center / and right divs get misaligned. This basically shows exactly what i am refering to. here is the example in IE8 and everything works ok http://es.drop.io/ern0fye/asset/ie8-jpg And here is the problem (this example is running in IE8 with compat mode set to IE7) http://es.drop.io/ern0fye/asset/ie7-jpg I seem to remember there being a bug in IE6/7 with lineheight or similar but i don't recall exactly. I will paste the CSS and HTML below it is very very simple. Basically there is a left div that holds the left corner image and center div which has a background of RED which is the same as the corner images and finally a right div which holds the right corner image. I would appreciate any input anyone has. Thanks in advance. Here is the CSS .vl-top-left { float:left; width:12px; height:12px; } .vl-top-center { float:left; width: 485px; background-color: #F04A23; height:12px; } .vl-top-right { float:left; height:12px; width:12px; } and the HTML is :- <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" > <head> <title></title> <link href="Stylesheet1.css" rel="stylesheet" type="text/css" /> </head> <body> <div class="vl-top-left"> <img src="content/images/esquina_sup_izq.gif" width="12" height="12"> </div> <div class="vl-top-center"> &nbsp; </div> <div class="vl-top-right"> <img src="content/images/esquina_sup_der.gif" width="12" height="12"> </div> </body> </html> EDIT Applied also margin:0 and padding:0 on the body and on each DIV but still the left and right div drops down as per the screenshot

• [JavaScript-CSS-Firefox] Cannot change borderColor of TD

  - by Tadeus Prastowo

  Using JS to set the background color of a TD is fine. But, setting the border color is problematic in FF 3.0.18 although IE 6 doesn't experience this. FF is problematic in that it requires the TD element to have an attribute style initialized to border-style: solid. Without that, setting border color of a TD won't work. Is this known bug? How do I set the border color without having to set style attribute as well as the initialization value? I know another trick of setting the class attribute instead of setting the border color directly. Is this an indication that somehow TD hates having its border color set dynamically? Is this known as well? The problematic code is below (the goal is find out why setting the border color of simple truth 1 does not work while simple truth 3 works when I employ the trick described above): <html> <head> <title>Quirks FF 3.0.18</title> <style type="text/css"> table { border-collapse: collapse; } </style> <script type="text/javascript"> function changeBgColor() { document.getElementById('simple').style.backgroundColor='yellow'; document.getElementById('simple2').style.backgroundColor='yellow'; document.getElementById('simple3').style.backgroundColor='yellow'; } function quirk(id) { var x = document.getElementById(id); x.style.border = '2px solid red'; } </script> </head> <body> <input type="button" onclick="changeBgColor()" value="Change background color"/> <input type="button" onclick="quirk('simple')" value="Change border color 1"/> <input type="button" onclick="quirk('simple2')" value="Change border color 2"/> <input type="button" onclick="quirk('simple3')" value="Change border color 3"/> <table> <tr><td id="simple">Simple truth 1</td></tr> </table> <table> <tr><td><span id="simple2">Simple truth 2</span></td></tr> <table> <tr><td id="simple3" style="border-style: solid">Simple truth 3</td></tr> </table> </body> </html>

• F# Add Constructor to a Record?

  - by akaphenom

  Basically I want to have a single construct to deal with serializing to both JSON and formatted xml. Records workd nicley for serializing to/from json. However XmlSerializer requires a parameterless construtor. I don't really want to have to go through the exercise of building class objects for these constructs (principal only). I was hoping there could be some shortcut for getting a parameterless constructor onto a record (perhaps with a wioth statement or something). I can't get it to behave - has anybody in the community had any luck? module JSONExample open System open System.IO open System.Net open System.Text open System.Web open System.Xml open System.Security.Authentication open System.Runtime.Serialization //add assemnbly reference System.Runtime.Serialization System.Xml open System.Xml.Serialization open System.Collections.Generic [<DataContract>] type ChemicalElementRecord = { [<XmlAttribute("name")>] [<field: DataMember(Name="name") >] Name:string [<XmlAttribute("name")>] [<field: DataMember(Name="boiling_point") >] BoilingPoint:string [<XmlAttribute("atomic-mass")>] [<field: DataMember(Name="atomic_mass") >] AtomicMass:string } [<XmlRoot("freebase")>] [<DataContract>] type FreebaseResultRecord = { [<XmlAttribute("code")>] [<field: DataMember(Name="code") >] Code:string [<XmlArrayAttribute("results")>] [<XmlArrayItem(typeof<ChemicalElementRecord>, ElementName = "chemical-element")>] [<field: DataMember(Name="result") >] Result: ChemicalElementRecord array [<XmlElement("message")>] [<field: DataMember(Name="message") >] Message:string } let getJsonFromWeb() = let query = "[{'type':'/chemistry/chemical_element','name':null,'boiling_point':null,'atomic_mass':null}]" let query = query.Replace("'","\"") let queryUrl = sprintf "http://api.freebase.com/api/service/mqlread?query=%s" "{\"query\":"+query+"}" let request : HttpWebRequest = downcast WebRequest.Create(queryUrl) request.Method <- "GET" request.ContentType <- "application/x-www-form-urlencoded" let response = request.GetResponse() let result = try use reader = new StreamReader(response.GetResponseStream()) reader.ReadToEnd(); finally response.Close() let data = Encoding.Unicode.GetBytes(result); let stream = new MemoryStream() stream.Write(data, 0, data.Length); stream.Position <- 0L stream let test = // get some JSON from the web let stream = getJsonFromWeb() // convert the stream of JSON into an F# Record let JsonSerializer = Json.DataContractJsonSerializer(typeof<FreebaseResultRecord>) let result: FreebaseResultRecord = downcast JsonSerializer.ReadObject(stream) // save the Records to disk as JSON use fs = new FileStream(@"C:\temp\freebase.json", FileMode.Create) JsonSerializer.WriteObject(fs,result) fs.Close() // save the Records to disk as System Controlled XML let xmlSerializer = DataContractSerializer(typeof<FreebaseResultRecord>); use fs = new FileStream(@"C:\temp\freebase.xml", FileMode.Create) xmlSerializer.WriteObject(fs,result) fs.Close() use fs = new FileStream(@"C:\temp\freebase-pretty.xml", FileMode.Create) let xmlSerializer = XmlSerializer(typeof<FreebaseResultRecord>) xmlSerializer.Serialize(fs,result) fs.Close() ignore(test)

• Ajax comments form in ASP.NET MVC2, howto?

  - by Artiom Chilaru

  I've been playing around with different aspects of MVC for some time now, and I've reached a situation where I'm not sure what would be the best way to solve a problem. I'm hoping that the SO community will help me out here :P I've seen a number of examples of Ajax.BeginForm on the internet, and it seems like a very nifty idea. E.g. you have a dropdown where you select a customer - and on selecting one it will load this client's details in some placeholder on the page. This works perfectly fine. But what to do if you want to tie in some validation in the box? Just hypothetically, imagine an article page, and user comments in the bottom. Below the comments area there's an ajax-y "Add comment" box. When a user adds a comment, it will appear in the comments area, below the last comment there. If I set the Ajax.BeginForm to Append the result of the call to the Comments area, it will work fine. But what if the data posted is not valid? Instead of appending a "successful" comment to the comments area I have to show the user validation errors. At this point I decided that the area INSIDE the Ajax.BeginForm will be inside a partial, and the form's submits will return this partial. Validation works fine. On each submit we reload the contents inside the form element. But how to add the successful comment to the top? Other things to consider: The comment form also has a "Preview" button. When the user clicks on Preview, I should load the rendered comment into a preview box. This will probably be inside the form area as well. I was thinking of using Json results instead. When the user submits the form, the server code will generate a Json object with a Success value, and html rendered partials as some properties. Something like { "success": true, "form": "<html form data>", "comment": "successful comment html to inject into the page" } This would be a perfect solution, except there's no way in MVC to render a partial into a string, inside the controller (separation of context, remember?). So.. what should I do then? Any "correct" way to implement this? Anyone???

• .NET RegEx "Memory Leak" investigation

  - by Kevin Pullin

  I recently looked into some .NET "memory leaks" (i.e. unexpected, lingering GC rooted objects) in a WinForms app. After loading and then closing a huge report, the memory usage did not drop as expected even after a couple of gen2 collections. Assuming that the reporting control was being kept alive by a stray event handler I cracked open WinDbg to see what was happening... Using WinDbg, the !dumpheap -stat command reported a large amount of memory was consumed by string instances. Further refining this down with the !dumpheap -type System.String command I found the culprit, a 90MB string used for the report, at address 03be7930. The last step was to invoke !gcroot 03be7930 to see which object(s) were keeping it alive. My expectations were incorrect - it was not an unhooked event handler hanging onto the reporting control (and report string), but instead it was held on by a System.Text.RegularExpressions.RegexInterpreter instance, which itself is a descendant of a System.Text.RegularExpressions.CachedCodeEntry. Now, the caching of Regexs is (somewhat) common knowledge as this helps to reduce the overhead of having to recompile the Regex each time it is used. But what then does this have to do with keeping my string alive? Based on analysis using Reflector, it turns out that the input string is stored in the RegexInterpreter whenever a Regex method is called. The RegexInterpreter holds onto this string reference until a new string is fed into it by a subsequent Regex method invocation. I'd expect similar behaviour by hanging onto Regex.Match instances and perhaps others. The chain is something like this: Regex.Split, Regex.Match, Regex.Replace, etc Regex.Run RegexScanner.Scan (RegexScanner is the base class, RegexInterpreter is the subclass described above). The offending Regex is only used for reporting, rarely used, and therefore unlikely to be used again to clear out the existing report string. And even if the Regex was used at a later point, it would probably be processing another large report. This is a relatively significant problem and just plain feels dirty. All that said, I found a few options on how to resolve, or at least work around, this scenario. I'll let the community respond first and if no takers come forward I will fill in any gaps in a day or two.

• iPhone MailComposer class UIViewController dismissModalViewControllerAnimated issues

  - by Scott Pendleton

  I created a class to launch the MailComposer so that my iPhone app would only have one place to go when generating various kinds of e-mail: some with attachments, some not. Some with pre-filled addresses, some not. I didn't want my class implement UIViewController, but it has to so it can be the delegate for the MailComposer. Otherwise, the view controllers that call my class would themselves have to be delegates for the MailComposer, which defeats the purpose. The downside of having my class be a view controller is that it has to load to the screen before it can modally bring up the MailComposer. Unfortunately, view controllers can't be transparent. The effect is, whatever is on screen gets covered by a solid white view controller for a moment before the MailComposer appears. I could maybe live with that, but not this: after the MailComposer goes away, I'm left with my blank view controller occupying the screen. I ought to be able to get rid of it from within itself by calling this: [self.parentViewController dismissModalViewControllerAnimated:NO]; But that dies a horrible death: "Loading 43365 stack frames..." Has my class -- a UIViewController that pre-fills and then launches a MailComposer -- lost track of its parentViewController? It isn't nil, because I've tested for that. As launched from within the current view controller... // My class is called Email. Email *oEmail = [[[Email alloc] init] retain]; // Red, to remind myself that I'd like to someday learn to make it transparent. oEmail.view.backgroundColor = [UIColor redColor]; // Pre-fill whatever fields you want, and specify attachments. oEmail.EmailSubject = @"I am truly stumped"; // This has to go on screen first. [self presentModalViewController:oEmail animated:NO]; // Then this can happen, which brings up the MailComposer. [oEmail f_SendEmail]; // Commenting out the next line didn't help, so I turned it back on. [oEmail release]; Inside the class, you need the mailComposeController:didFinishWithResult:error: method to make the MailComposer go away, and for that to happen, the class has to be the MFMailComposeViewControllerDelegate. Here's what happens in there: // This gets rid of the mail composer. [self dismissModalViewControllerAnimated:YES]; // This never fails to get rid of other modal view controllers when called // from within those controllers, but boy does it not work here. [self.parentViewController dismissModalViewControllerAnimated:NO]; If you can help me, I will be truly thankful!
