• Disabling itemrenderer Hovered state

  - by duder

  My itemrenderer has 2 custom states, no hovered state, and no normal state <s:states> <s:State name="state1" /> <s:State name="state2" /> </s:states> When I initialize it, I force it to go to state2. The problem is that when it's hovered over, it relapses back to the first state state1. It's kind of weird since I don't really have a hovered state. Anyone knows how to prevent this from happening? maybe by somehow disabling the hover effect?

• GUI freezing after datagridviews have been updated using backgroundworkers

  - by Jhon

  I have made an application which runs three backgroundworkers simultaneously. It basically updates three datagridviews, which it is doing spot on. My problem is if I press maximizebox button or anywhere in any of the datagridview the program hangs for quite a long time. I am able to use the horizontal scroll but not vertical scrolls. I have tried Backgroundworker_runworkercompleted and it fires as required after threads have updated their respective datagridviews. Is it a normal behaviour or am i doing something wrong any suggestions would be helpful. P.S: I have run the whole program using step method and their is no infinite loop in the code. Thanks in advance Jhon

• My code works in Debug mode, but not in Release mode.

  - by Nima

  Hi, I have a code in Visual Studio 2008 in C++ that works with files just by fopen and fclose. Everything works perfect in Debug mode. and I have tested with several datasets. But it doesn't work in release mode. It crashes all the time. I have turned off all the optimizations, also there is no dependency to anything(in the linker), and also I have set these: Optimization: Disabled(/Od) Keep Unreferenced Data. Do Not Remove Redundant Optimize for Windows98: NO I still keep wondering how it should not work under these circumstances. What else should I turn off to let it works as in debug mode? I think if it works in release mode but not in debug mode, it might be a coding fault but the other way looks weird. isn't it? I appreciate any help. --Nima

• PHP/Javascript - get php variable within javascript

  - by McNabbToSkins

  I have run into an interesting problem. I am currently developing php page and need to access a php variable within the javascript onload. $(document).ready(function() { var temp = <?php $page_id ?> } is this valid? I know that this might seem weird and not be allowed but I am developing a page that has two popup windows. The windows are created using the same view template and there is no way to distinguish between each other. If I stored a hidden value on the page with information unique to the page like so <input type="hidden" value="<?php $page_id ?> id="page_id" /> if there are two views open at the same time there is no way for me to get a unique page id like so var temp = $("#page_id").val(); Because there are two views witht he same input id that is not unique. Long story short is it valid to reference a php variable in the javascript.

• How can I share an OnEnter event for a TcxGrid ?

  - by Roland Bengtsson

  I want to standardize the behaviour on an Devexpress TcxGrid. So I have a unit ClientData with a event: procedure TClientData.grdOnEnter(Sender: TObject); begin mnuCxGridStandardMenu.Grid := TcxGrid(Sender); end; If I try to use that event from a TcxGrid.OnEnter event in another unit it refuse to work. If I paste in ClientData.grdOnEnter then a dialog says it is not an valid identifier. Is it possible to share an event for several units in Delphi 2007 ?

• Assignments failing

  - by Andrei Krotkov

  I'm debugging part of a large project in Visual Studio 2005, and stepping through the code line by line. int speed = this->values.speed; int ref = this->values.ref_speed; After stepping past the first line, values.speed has a value of 61, but for some reason, speed is getting assigned the value 58. After the second line, values.ref_speed has a value of 58, but ref gets assigned the value 30. When paused, you can see that the original values are in fact 61 and 58 respectively, but the values getting stored are different. What is causing this behaviour?

• Do I always have to supply Tkx's -command argument with an anonymous subroutine?

  - by Zaid

  I find it a bit weird that I have to wrap defined subroutines anonymously when specifying the -command argument for Tkx widgets. The example from TkDocs demonstrates this: my $cb = $frm->new_ttk__button ( -text => "Calculate", -command => sub {calculate();} ); sub calculate { $meters = int(0.3048*$feet*10000.0+.5)/10000.0 || ''; } Why doesn't it work when I write -command => &calculate() or -command => \&calculate()?

• Why is QProcess converting the '=' in my arguments to spaces

  - by dagorym

  I've run into a weird error with a Qt program running on Windows. The program uses QProcess to spawn a child process wit two arguments. The program and arguments passed to the QProcess::start() method are of the form: "batchfile.bat" "--option1=some_value" "--option2=some_other_value\with_a\path" For some reason by the time those options get to the batchfile for processing the equals signs have been converted to spaces and it now looks like: "batchfile.bat" "--option1 some_value" "--option2 some_other_value\with_a\path" because of this, the processing fails. Any ideas what could be causing the equal signs to be replaced by spaces? I'm using the mingw build of the QT 4.6.3 framework found on the Qt download page.

• jqgrid - edit form field combobox not defaulting to selected row value after first edit

  - by ooo

  i am using jqgrid with asp.net-mvc. I have an edit form (using jqmodal) which works great but for some reason one combobox field doesn't default to the current selected row after the first time i bring up the edit form. the weird thing is that i have many other comboboxes which work fine every time and i don't see any real difference. here is an example of the field that doesn't work: { name: "TechOwner", index: "TechOwner", width: 70, editable: true, edittype: "select", editoptions: { dataUrl: "/Person/GetSelectData" }, editrules: { required: true} }, and here is a field that works fine: { name: "FundingType", index: "FundingType", align: "left", width: 25, editable: true, edittype: "select", editoptions: { dataUrl: "/Project/FundingGetSelectData" }, editrules: { required: true} }, the dropdown is getting populated with all options (including the current selected row option) but its just defaulting to the top item) instead of one that matches the current row. is there anything to look out for here that may cause this behavior?

• Fatal error: Call to a member function item() on a non-object

  - by Andree

  Hi there! I have a weird problem. I have a PHP class with the following method: public function __construct() { parent::__construct(); $this->CI =& get_instance(); $this->log(method_exists($this->CI->config, 'item')); // Outputs TRUE $firephp_enabled = $this->CI->config->item('firephp_enabled'); // Error point $this->setEnabled($firephp_enabled); } $this->CI->config has a method item, and it has been verified using method_exists(). But when I call $this->CI->config->item(), I got the following error: Fatal error: Call to a member function item() on a non-object Can anyone tell me what might be the problem here? Thanks, Andree.

• First Call to a Controller, Constant is defined, Second call, "uninitialized constant Oauth"?

  - by viatropos

  I am trying to get the OAuth gem to work with Rails 3 and I'm running into this weird problem... (independent of the gem, I think I've run into this once before) I have a controller called "OauthTestController", and a model called "ConsumerToken". The model looks like this. require 'oauth/models/consumers/token' class ConsumerToken < ActiveRecord::Base include Oauth::Models::Consumers::Token end When I go to "/oauth_test/twitter", it loads the Oauth::Models::Consumers::Token module and I'm able to connect to twitter no problem. But the second time I try it (just refresh the /oauth_test/twitter url), it gives me this error: NameError (uninitialized constant Oauth): app/models/consumer_token.rb:4 app/models/twitter_token.rb:2 app/controllers/oauth_test_controller.rb:66:in `load_consumer' Why is that? It has something to do with load paths or being in development mode maybe?

• Access Violation Exception only appearing when running C# app without debugger attached

  - by Jon

  I have an application that works fine in Visual Studios 2008, and I am trying to get it into VS 2010 in order to use .NET 4, and I have a really weird problem. When I run the code from either Release mode or Debug mode with the debugger attached (F5), I have no problems running the program. However, when I run the program from either Release or Debug without the debugger attached (Shift+F5), I get an Access Violation Exception when I attempt to run some code in a dll from GDCM. I've created the dlls by using CMake and Swig and following the instructions here adjusting the instructions where necessary to build for VS 2010 and .NET 4. Does any one have any ideas why this is happening and how I can fix it?

• Problem making ant compile my classes present in different Eclipse projects into single destination

  - by KCore

  I have close to about 20 projects in my Eclipse workspace. They are interdependent. Now I want to build all of them in a single war file. The thing is eclipse does it nicely... if I create a Dynamic Web Project and link sources of all the 20 projects. But I want to automate the entire process and want to be able to run a script (ant maybe..) and deploy a war in my app server. My approach: I started with a simple approach. I tried to sequentially build each project (javac task) with destination directory as web-inf of my war. But it is giving me weird errors like : package " ** " not found,when it shows the same all the required classes in classpath (I used verbose) Do you think, a continous integration engine will be better for my case (20 projects..) I saw Team City, but didnt get it the first time...

And it compiles C code well. but I found a weird thing for NOT operations. if i make code like int a; func(!a); and i studied MIPS instructions with text book that says "MIPS converts NOT operation to 'nor with zero'" So i thought it would converted like nor a a $zero but my compiler converts xori a a 0x0 sltu a 1 /////////////////////////////////////// i compiled the code with 'myaccount mipsel-unknown-linux-gnu-gcc -S myfilename.c' and it makes myfilename.s file.. what am i missing??

• Drag drop open file in Macvim split window?

  - by Jon

  Hello. I like to use the split window feature in Vim. However I cannot seem to drag drop new files into the different sections. Doing so will just open a new tab. I don't like using tabs as I still need to flick between them and not much different to using separate windows. Is there anyway I can change this behaviour? It works fine on Windows gVim and Im using the same vimrc file.

• Why can't I publish MVC project

  - by Vnuk

  I'm having problems publishing my MVC project. When I do publish and upload everything to web server I get this: [InvalidOperationException: The view 'Index' or its master could not be found. The following locations were searched: ~/Views/Home/Index.aspx ~/Views/Home/Index.ascx ~/Views/Shared/Index.aspx ~/Views/Shared/Index.ascx] Weird thing is that Index.aspx exists in ~/Views/Home/, but IIS cannot find it there. If I copy entire project to web server and let asp.net compile it on the fly it works like a charm. My routing code: routes.MapRoute( _ "Default", _ "{controller}/{action}/{id}", _ New With {.controller = "Home", .action = "Index", .id = ""} _ ) routes.MapRoute("Root", "", New With {.controller = "Home", .action = "Index", .id =""}) I'm using IIS7 on Windows 2008 Web server. ASP.NET MVC 1.0, Visual Studio 2008. I've tried it local with IIS7 on Windows 7 - same error.

• How's my pygame code?

  - by Isaiah

  I'm still getting the hang of lots of things and thought I should post some code I made with pygame and get some feedback^^. I posted code here: http://urlvars.com/code/snippet/39272/my-bouncing-program http://urlvars.com/code/snippet/39273/my-bouncing-program-classes There's tome things that I implemented that I'm not using yet I just realized like a timer at the bottom of the main while loop. If my code isn't readable, I'm sorry, I'm self taught and this is the first code I've ever posted anywhere. By the way I made some variables that take the screensize and half it to find a point to spit out the squares, but when I try to use it, it makes a weird effect :/ Try switching the list i have in the newbyte() function with the halfScreen variable and see it freak out o.O thank you

• Graphics/Bitmap Limits?

  - by Dean

  Im having some weird problems with Graphics and Bitmap. I have a Graphics Object that is displayed on a PictureBox and im capturing the MouseMove and MouseClick Events that give X and Y Position of the Mouse on the Image but if the Y Position goes Bigger then 32775 it then goes into Negatives which means everything breaks. And if the Image is Bigger then 65535 it then stops displaying the Image. Any Ideas how these problems can be fixed? Thanks Example Code: http://pastebin.com/YEX0XD1q Just Click Make 10,000 Bigger about 4 times then scroll down and on the right it will show the mouse X and Y position and as you move down through the image and hover over the Red Area if you go down enough it will go into Negative Y.

• emacs indentation in asm mode

  - by Gauthier

  I am looking for the equivalent of c-indent-level and ruby-indent-level, for asm-mode. That is, I want to force the indentation to 4 spaces, and I want them to be replaced with blanks. What I've seen tells me it does not exist for asm-mode. Could someone please tell me this is wrong? I tried this also: http://stackoverflow.com/questions/69934/set-4-space-indent-in-emacs-in-text-mode , to no av. I have tried: (setq tab-width 4) (setq indent-line-function 'insert-tab) (setq asm-indent-level 4) This works however: (custom-set-variables '(tab-stop-list (quote (4 8 12 16 20 24 28 32 36 40 44 48 52 56 60 64 68 72 76 80 84 88 92 96 100 104 108 112 116 120)))) But I wonder if there is a way to define that for asm-mode only. What if I wanted to keep the default tab behaviour for other modes?

• iPhone app quits on launch

  - by Brammie

  I created an app using the 3.1.2 toolchain on linux.. it compiles and links normally, and in the makefile i upload my app (something) like this: @scp ./blabla [email protected]/Applications/Helloworld.app/ @ssh [email protected] "cd /Applications/Helloworld.app; ldid -S Helloworld_; killall; springBoard" when i launch my app it immediatly quits. according to google ldid failed, so i tried to do it manually. ldid did give an error, but after rebooting the error was fixed. The app still doesn't launch. the weird part of my problem is that an example i had DID work, but doesn't work anymore now. (p.s. i built the toolchain by following this guide)

• XmlSerializer Performance Issue when Specifying XmlRootAttribute

  - by Dougc

  I'm currently having a really weird issue and I can't seem to figure out how to resolve it. I've got a fairly complex type which I'm trying to serialize using the XmlSerializer class. This actually functions fine and the type serializes properly, but seems to take a very long time in doing so; around 5 seconds depending on the data in the object. After a bit of profiling I've narrowed the issue down - bizarrely - to specifying an XmlRootAttribute when calling XmlSerializer.Serialize. I do this to change the name of a collection being serialized from ArrayOf to something a bit more meaningful. Once I remove the parameter the operation is almost instant! Any thoughts or suggestions would be excellent as I'm entirely stumped on this one!

• What is the full "for" loop syntax in C (and others in case they are compatible) ?

  - by fmsf

  I have seen some very weird for loops when reading other people's code. I have been trying to search for a full syntax explanation for the for loop in C but it is very hard because the word "for" appears in unrelated sentences making the search almost impossible to Google effectively. This question came to my mind after reading this thread which made me curious again. The for here: for(p=0;p+=(a&1)*b,a!=1;a>>=1,b<<=1); In the middle condition there is a comma separating the two pieces of code, what does this comma do? The comma on the right side I understand as it makes both a>>=1 and b<<=1. But within a loop exit condition, what happens? Does it exit when p==0, when a==1 or when both happen? It would be great if anyone could help me understand this and maybe point me in the direction of a full for loop syntax description.

  Hello, I want to use interface in Action signature. So I've tried make own ModelBinder by deriving DefaultModelBinder: public class InterfaceBinder<T> : DefaultModelBinder where T: new() { protected override object CreateModel(ControllerContext controllerContext, ModelBindingContext bindingContext, Type modelType) { return base.CreateModel(controllerContext, bindingContext, typeof(T)); } } public interface IFoo { string Data { get; set; } } public class Foo: IFoo /*other interfaces*/ { /* a lot of */ public string Data { get; set; } } public class MegaController: Controller { public ActionResult Process( [ModelBinder(typeof(InterfaceBinder))]IFoo foo){/bla-bla-bla/} } But it doesn't work. Does anybody have idea how release this behaviour? And yes, I know that I can make my own implementation of IModelBinder, but I'm looking for easier way.

• strange Problem with WPF Textbox stringformat - Cursor moves back

  - by Emad

  I am using WPF 4.0 TextBox and binding. I am using StringFormat to format the number as currency. the XAML looks like this: <TextBox Text="{Binding Path=ValueProperty, ValidatesOnDataErrors=True, ValidatesOnExceptions=True, StringFormat={}{0:C}, UpdateSourceTrigger=PropertyChanged}"> </TextBox> Everything seems to work correctly except for a strange behavior: When for example a user types in 12: right after typing 1, the value in the textbox becomes $1.00 and the weird thing is the the cursor is moved to be between the $ and the 1. So when a user simply types in 12, the result becomes $21.00. How can I fix this strange behavior?
