• Silverlight Pixel Shader resource "not found"; what should the URI be?

  - by Grank

  So I've written and compiled an HLSL pixel shader with Shazzam, placed the resulting .ps file in my project, and am trying to instantiate it. No matter what URI I put, Blend tells me that the resource can't be found whenever I try to view any xaml designer, and Visual Studio just shows me a blank page, both in design view and if I try to run the application. This is a Silverlight 4 SketchFlow project, in Blend 4 RC and Visual Studio 2010. I've tried both Resource and EmbeddedResource as the Build Action for the .ps file, neither make any difference (I'm pretty sure it's supposed to be set to Resource). I've tried the following URI formats: "ShaderFileName.ps" "/ShaderFileName.ps" "AssemblyName;component/ShaderFileName.ps" "/AssemblyName;component/ShaderFileName.ps" I also tried moving the shader file from the Screens assembly to the root assembly (that's how SketchFlow projects are created) and that didn't help either. Anyone have any thoughts?

• Redoundant code in exception handling

  - by Nicola Leoni

  Hi, I've a recurrent problem, I don't find an elegant solution to avoid the resource cleaning code duplication: resource allocation: try { f() } catch (...) { resource cleaning code; throw; } resource cleaning code; return rc; So, I know I can do a temporary class with cleaning up destructor, but I don't really like it because it breaks the code flow and I need to give the class the reference to the all stack vars to cleanup, the same problem with a function, and I don't figure out how does not exists an elegant solution to this recurring problem.

• Stable Scala 2.8 plugin

  - by Felix

  Does anyone know if there exists a stable version of the Scala plugin for eclipse, running with Scala 2.8 (any version of scala 2.8...RC or beta or whatever). I like the fact that it compiles 10 times faster than the netbeans plugin, but it is very unstable, and auto-imports doesnt work. Also, sometimes it cant find classes when I hit "run", then I have to clean it again. This is with some random nightly build of the 2.8 eclipse scala plugin. Is there a stable version? If so, can you link me to it? Thanks in advance :)

• Developing Qt applications in Unix systems using Qt Creator

  - by Jake Petroules

  I'm developing a Qt application in Linux using Qt Creator (2.1 RC). I've created 2 projects, and used the wizard to add the library project to the application project. However when I run it, I receive the error: /home/jakepetroules/silverlock/silverlock-build-desktop/desktop/silverlock: error while loading shared libraries: libsilverlocklib.so.1: cannot open shared object file: No such file or directory Is there some qmake variable I can set so that Qt Creator will set up the environment properly to run? It's quite annoying to have to copy all the files to another directory with a launcher script just to be able to test the build. On Windows it works perfectly - Qt Creator automatically adds the directories containing the DLLs to the PATH when it runs your application (where running it from Explorer would say DLL not found). Mac OS X is even worse, having to run install_name_tool on everything... So how can I set up my qmake files so everything works right from the run button in Qt Creator? Kind of hard to debug without this ability, too.

• System context menu Icon not transparent like WinRAR

  - by Samir

  I added a icon at the system context menu(the popped up menu when we right mouse click on any file/foler). But the icon is not transparent(in xp its not notice able, but in vista/win7 it is clearly visible) there is a white background beneath the icon. But WinRAR or TortoiseSVN icons don't have any white background, they are transparent. I tried the following C++ code: #define BITMAP_MAIN 201 //in resource.h BITMAP_MAIN BITMAP "main.bmp" // in .rc file // showing icon in menu... HBITMAP imgMain = LoadBitmap( aHinstance, MAKEINTRESOURCE(BITMAP_MAIN) ); SetMenuItemBitmaps ( hSubmenu, uMenuIndex, MF_BYPOSITION, imgMain, imgMain); [main.bmp is 16X16] Also the icon(.bmp) is not shown fully in non-english OS. So is there be any special technique to make the icon in the system context menu transparent like WinRAR?

• Get scrollheight cross-browser through Selenium

  - by hh354

  Hi, I'm working on a project which is using Selenium and I'd like to try to get the full web page height cross-browser and cross-platform. IE8 is being stubborn as always, is there anybody who has an idea of how to solve this? The problem: When you scroll down a page for e.g. 500px and you keep doing this until the bottom of the page, the last scroll will be less than 500px. I need to know how much this last scroll was. Two ways of solving: 1) Find the offset that has been scrolled each time (works everywhere except IE8) 2) Find the total height of the webpage I know JQuery's height() function does this but I can't use this function from Selenium RC. If you know a way of calling JQuery functions through Selenium or any other solution, please tell! Cheers, Henry

• I get a 400 Bad Request error while using django-piston

  - by Cheezo

  Hello, I am trying to use Piston to provide REST support to Django. I have implemented my handlers as per the documentation provided . The problem is that i can "read" and "delete" my resource but i cannot "create" or "update". Each time i hit the relevant api i get a 400 Bad request Error. I have extended the Resource class for csrf by using this commonly available code snippet: class CsrfExemptResource(Resource): """A Custom Resource that is csrf exempt""" def init(self, handler, authentication=None): super(CsrfExemptResource, self).init(handler, authentication) self.csrf_exempt = getattr(self.handler, 'csrf_exempt', True) My class (code snippet) looks like this: user_resource = CsrfExemptResource(User) class User(BaseHandler): allowed_methods = ('GET', 'POST', 'PUT', 'DELETE') @require_extended def create(self, request): email = request.GET['email'] password = request.GET['password'] phoneNumber = request.GET['phoneNumber'] firstName = request.GET['firstName'] lastName = request.GET['lastName'] self.createNewUser(self, email,password,phoneNumber,firstName,lastName) return rc.CREATED Please let me know how can i get the create method to work using the POST operation?

• How can I make sure the Sphinx daemon runs?

  - by Ethan

  I'm working on setting up a production server using CentOS 5.3, Apache, and Phusion Passenger (mod_rails). I have an app that uses the Sphinx search engine and the Thinking Sphinx gem. According to the Thinking Sphinx docs... If you actually want to search against the indexed data, then you’ll need Sphinx’s searchd daemon to be running. This can be controlled using the following tasks: rake thinking_sphinx:start rake ts:start rake thinking_sphinx:stop rake ts:stop What would be the best way to ensure that this takes place in production? I can deploy my app, then manually run rake thinking_sphinx:start, but I like to set things up so that if I have to bounce the server, everything will come back up. Should I put a call to that Rake task in an initializer? Or something in rc.local?

• Performance problem Loading Dataset inside a virtual.

  - by ShaneH

  Host Configuration: HP EliteBook 8530w 4G Ram Win7 Ultimate 64Bit RC SQL Server 2005 64bit Developer Edition Virtual: Windows Virtual PC 1G Ram allocated Integration Services installed Windows XP 64bit Up to date service packs and .Net framework through 3.5 SP1 Sharing the Gigabit network adapter of the Host I have a simple .Net console application which loads a dataset of approximately 37K rows. Running the application on the host executes in approximately 4 seconds. Running inside the virtual takes 729 seconds. The size of the application grows to about 65Mb when the dataset is finished loading, no calculated columns or event handlers are attached. [edit] I changed the virtual to use a loopback adapter to communicate with the host and performance is now on par with running on hardware. Any ideas as to why it would going over the network adapter be almost 200x longer? TraceRt shows that the connection is only one hop. Thanks, Shane Holder

• How to prevent "This program might not have installed correctly" messages on Vista

  - by Jason

  I have a product setup executable that copies some files to the user's hard drive. It's not a typical installer in the normal sense (it doesn't add anything to the Start Menu or Program Files folders). Each time the setup program is run on Vista, after the exe terminates, Vista produces a task dialog: This program might not have installed correctly Reinstall using recommended settings This program installed correctly Is there a function I need to call from the exe or registry entry to set, to indicate to the operating system that the program installed correctly (or to at least supress this message)? Related questions: http://stackoverflow.com/questions/1069135/this-program-might-not-have-installed-correctly-message-in-windows-7-rc (for Windows 7-specific issues)

• Best cross-platform solution for network server?

  - by Anonymous

  Hi, im starting a new project and for the first time i want to be cross-platform. But the tricky is my project would involve listen server, cryptos etc., etc. So i was wondering what is the best solution for cross-platform development (OpenSSL, instead of MSCrypto etc.) that would be easy to write with VS2010 (yeah the RC). The language is still not specified (depends on witch we would be easier) but im leaning to Visual C++. In Cross-Platform i mean windows/generic unix compilation.

• Bash variable kills script execution

  - by Kyle Terry

  Sorry if this is better suited at serverfault, but I think it learns more towards the programming side of things. I have some code that's going into /etc/rc.local to detect what type of touch screen monitor is plugged in and changes out the xorg.conf before launching X. Here is a small snippet: CURRENT_MONITOR=`ls /dev/usb | grep 'egalax_touch\|quanta_touch'` case $CURRENT_MONITOR in '') CURRENT_MONITOR='none' ;; esac If one of those two touch screens is plugged in, it works just fine. If any other monitor is plugged in, it stops at the "CURRENT_MONITOR=ls /dev/usb | grep 'egalax_touch\|quanta_touch'." For testing I touched two files. One before creating CURRENT_MONITOR and one after CURRENT_MONITOR and only file touched before is created. I'm not a bash programmer so this might be something very obvious.

• CUDA & VS2010 problem

  - by Kristian D'Amato

  I have scoured the internets looking for an answer to this one, but couldn't find any. I've installed the CUDA 3.2 SDK (and, just now, CUDA 4.0 RC) and everything seems to work fine after long hours of fooling around with include directories, NSight, and all the rest. Well, except this one thing: it keeps highlighting the <<< >>> operator as a mistake. Only on VS2010--not on VS2008. On VS2010 I also get several warnings of the following sort: C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\include\xdebug(109): warning C4251: 'std::_String_val<_Ty,_Alloc>::_Alval' : class 'std::_DebugHeapAllocator<_Ty>' needs to have dll-interface to be used by clients of class 'std::_String_val<_Ty,_Alloc>' Anyone know how this can be fixed?

• Why do my WPF UIElements NOT have OnPreview events?

  - by Matt.M

  I'm building a custom Silverlight UserControl which needs to listen to events using Preview/Tunneling, but for some reason the compiler is telling me they are not recognized or accessible. For example, I can add an event handler to MouseLeftButtonDown, but not PreviewMouseLeftButtonDown. This doesn't make sense because according to Microsoft (http://msdn.microsoft.com/en-us/library/system.windows.uielement_members(v=VS.100).aspx) all UIElements should have Preview events attached. Any ideas as to why this is happening? I'm using Visual Studio 2010 Trial, Blend 4 RC and .Net 4, if that makes a difference.

• Django: Localization Issue

  - by Eric

  In my application, I have a dictionary of phrases that are used throughout of the application. This same dictionary is used to create PDFs and Excel Spreadsheets. The dictionary looks like so: GLOBAL_MRD_VOCAB = { 'fiscal_year': _('Fiscal Year'), 'region': _('Region / Focal Area'), 'prepared_by': _('Preparer Name'), 'review_cycle':_('Review Period'), ... snip ... } In the code to produce the PDF, I have: fy = dashboard_v.fiscal_year fy_label = GLOBAL_MRD_VOCAB['fiscal_year'] rg = dashboard_v.dashboard.region rg_label = GLOBAL_MRD_VOCAB['region'] rc = dashboard_v.review_cycle rc_label = GLOBAL_MRD_VOCAB['review_cycle'] pb = dashboard_v.prepared_by pb_label = GLOBAL_MRD_VOCAB['prepared_by'] Now, when the PDF is produced, in the PDF, I don't see these labels but rather, I see: <django.utils.functional.__proxy__ object at 0x10106fdd0> Can somebody help me with this? How do I get the properly translated labels? Thanks Eric

• Why does Spring Security Core RC4 require Grails 2.3?

  - by bksaville

  On the Spring Security Core plugin GitHub repo, I see that Graeme on May 21st upped the required version of Grails from 2.0 to 2.3 before the RC4 version was released a couple of months later, but I don't see any explanation for why. Was it mismatched dependencies, bug reports, etc? I run a 2.2.4 app, and I would prefer not to upgrade at this point just to get the latest RC of spring security core. I understand if the upgrade to 3.2.0.RELEASE of spring security caused mismatched dependencies with older versions of Grails since I've run into the same issues before. This originally came up due to a pull request on the spring security OAuth2 provider plugin that I maintain. The pull request upped the required version to 2.3, and the requester pointed me to the RC4 release of core as the reason. Thanks for the good works as always!

• C++ - Resources in static library question

  - by HardCoder1986

  Hello! This isn't a duplicate of http://stackoverflow.com/questions/531502/vc-resources-in-a-static-library because it didn't help :) I have a static library with TWO .rc files in it's project. When I build my project using the Debug configuration, I retrieve the following error (MSVS2008): fatal error LNK1241: resource file res_yyy.res already specified Note, that this happens only in Debug and Release library builds without any troubles. The command line for Resources page in project configuration looks the same for every build: /fo"...(Path here)/Debug/project_name.res" /fo"...(Path here)/Release/project_name.res" and I can't understand what's the trouble. Any ideas? UPDATE I don't know why this happens, but when I turn "Use Link-Time Code Generation" option on the problem goes away. Could somebody explain why does this happen? I feel like MS-compiler is doing something really strange here. Thanks.

• Is it possible to make a PHP script run itself every hour or so without the use of a cronjob?

  - by Rob

  I'm pretty sure I've seen this done in a php script once, although I cant find the script. It was some script that would automatically check for updates to that script, and then replace itself if there was an update. I don't actually need all that, I just want to be able to make my PHP script automatically run every 30 minutes to an hour, but I'd like to do it without cronjobs, if its possible. Any suggestions? Or is it even possible? EDIT: After reading through a possible duplicate that RC linked to, I'd like to clarify. I'd like to do this completely without using resources outside of the PHP script. AKA no outside cronjobs that send a GET request. I'd also like to do it without keeping the script running constantly and sleeping for 30 minutes

• ssrs column groups disable multiple columns

  - by DKS

  I'm using ASP.NET 4.0 Visual Studio 2010 RC version Sql Server Report Services (SSRS) ReportViewer and are aware that columns only display on PDF export - not the preview. I want to use a matrix embedded in a table on a page that has multiple columns. I've done some testing and frustratingly found that if you have a tablix with at least one grouped column (even if there is only one displayed matrix-like column group) the columns seem to be disabled. Once I remove the tablix with a grouped column from the tablix from the report the report does multiple-columns. Does anyone know a way around this?

• C++ context menu image at left side showing partially, no fully

  - by Samir

  In C++ #define BITMAP_MAIN 201 //in resource.h BITMAP_MAIN BITMAP "main.bmp" // in .rc file // showing icon in menu... HBITMAP imgMain = LoadBitmap( aHinstance, MAKEINTRESOURCE(BITMAP_MAIN) ); SetMenuItemBitmaps ( hSubmenu, uMenuIndex, MF_BYPOSITION, imgMain, imgMain); The problem is in non-English XP OS the main.bmp is showing partially in the context menu. In Vista, Window7 main.bmp is showing just fine. Also in English XP its ok. But why the image is not showing fully in non-English XP? How would I use .ico file here instead of .bmp? This is to make the image transparent.

• How to run a recorded (HTML) selenium test from .NET

  - by Gaspar Nagy

  I run Selenium tests with Selenium RC from .NET (c#). In some cases, I would like to keep the test case source as HTML (to be able to modify it from Selenium IDE), but I would like to run/include these tests from my c# unit tests. Maybe it is obvious, but I can't find the API method in the Selenium Core to achieve this. Any idea how to do that? (I think the "includePartial" command in Selenium on Rails does the thing that I would need, but for c#.)

• I can't get areas working in VS2010

  - by devlife

  I just upgraded from VS2010 RC to RTM. Now my areas aren't working. I have a Profile area with a Home controller and an Action method Index(). If I try: http://localhost:4951/profile I get a 404 error saying that the resource can't be found. If I try http://localhost:4951/profile/home I get the same error. However, if I try http://localhost:4951/profile/home/index then the view is returned. Here is my ProfileAreaRegistration: public class ProfileAreaRegistration : AreaRegistration { public override string AreaName { get { return "Profile"; } } public override void RegisterArea(AreaRegistrationContext context) { context.MapRoute( "Profile_Unlock", "Profile/Unlock/{userID}/{unlockID}", new { controller = "Unlock", action = "Index" }, new { userID = new GuidRouteConstraint(), unlockID = new GuidRouteConstraint() } ); context.MapRoute( "Profile_default", "Profile/{controller}/{action}/{id}", new { action = "Home", id = UrlParameter.Optional } ); } Does anyone know what is going wrong?

• I wired up a z 80 using telephone wire and put a jump to 0000 0000 0000 0000

  - by john

  I put 1100 0011 0000 0000 0000 0000 in the 2764 eprom --- this is supposed to test the z80 -- I have a 555 timer running at 500 khz. Can this small program work with the z80 ? I looked at the address pins on a m465 oscilloscope. The address shows highs up to 0100 0000. I think it should only count to 0000 0000 0000 0011. Can the z80 be tested? The Santa Clara Valley also made the lm1871 radio control chip that could not show a high or a low without completing the entire rc loop.
