• Visual Studio Crashes when using Crystal Reports Group Editor

  - by Matthew Taylor

  I have a crystal report in my Visual Studio 2008 ASP.NET project, and when I choose "Group Expert" from the Crystal Reports - Report menu, Visual Studio crashes / hangs and I have to use Task Manager to close the program. This happens no matter how many times I try, and oddly enough it seems to work fine on another computer with the same project. Any help at all in the right direction would be greatly appreciated as I am pulling my hair out trying to figure this out. I am using Visual Studio 2008 SP1, SQL Server 2005 Developer SP2, Windows Vista Enterprise SP1, and the version of Crystal Reports that came with the Visual Studio installation.

• WCF RIA Services build error

  - by soren.enemaerke

  Hi I'm getting a strange error when building my WCF RIA Services Silverlight project in VS2008. In the output I have this message: C:\Program Files\MSBuild\Microsoft\Silverlight\v3.0\Microsoft.Ria.Client.targets(261,5): error : Failed to write the generated contents of 'C:\projects\[Path_To_Silverlight_Project]\Generated_Code\Analytics.Web.g.cs' to Visual Studio. ...and Visual Studio opens a dialog while building with the following: An editor or project is attempting to save a file that is modified in memory. Saving files during a build is dangerous and may result in incorrect build outputs in the future. Continue with save? The other members on my team seems to be doing just fine, but I can't get past this point (I can if I click 'Continue' which then generate the file just fine but I'm reluclant to do so). There must be some setup or similar that I'm missing here... PS: I'm currently on WinXP and WCF RIA Service beta

• fluentnhibernate and nhibernate validator version error

  - by Thad

  We have a project using FluentNibernate to map the entities. Now I need to add some format validation to these maps. For Nullable, Length and such we are currently using the mappings. I added NHibernate Validator to the project, but received a compile time error about needing NHibernate version 2.1.2.4000. So I upgraded to that version just to get a run-time error stating that it could not find NHibernate 2.1.0.4000. Could I write extension methods to do the validation using FluentNibernate? Do I have to recompile both using the same version of NHibernate? The preferred method would be to use a release of these. Any other device would appreciated.

• Text mining with PHP

  - by garyc40

  Hi, I'm doing a project for a college class I'm taking. I'm using PHP to build a simple web app that classify tweets as "positive" (or happy) and "negative" (or sad) based on a set of dictionaries. The algorithm I'm thinking of right now is Naive Bayes classifier or decision tree. However, I can't find any PHP library that helps me do some serious language processing. Python has NLTK (http://www.nltk.org). Is there anything like that for PHP? I'm planning to use WEKA as the back end of the web app (by calling Weka in command line from within PHP), but it doesn't seem that efficient. Do you have any idea what I should use for this project? Or should I just switch to Python? Thanks

• Is learning the Caché database hard coming from relational databases and object oriented programming

  - by Edelcom

  I am currently running the local version of Caché on my system in order to determine if I can (and will) take on a new possible project. The current project uses Delphi 7 as a front end calling a Caché dll where the business logic is stored in the database. I have a background of Sqlserver and Firebird (and before Access and Paradox) as databases. I use Delphi 7 for 95% of my Windows development, so I know about object programming. I would like to recieve opinions from persons having used Caché and either SqlServer, Firebird or Oracle and having developed in Delphi (or C++ or C# - an object oriented language). I have read the pro's and con's from other questions, but I am not asking for this, I need input from Caché developers. Thanks in advance.

• is there any easy way to auto generated code like this?

  - by Kevin Yang

  i have a file which will be used across many app projects. the only difference of these files is the webserice referrence name. code like this: public void Test(){ Kevin.ServiceReference1.Service1Client client = new Kevin.ServiceReference1.Service1Client(); // do something.... } like code above, the 'Kevin.ServiceReference1' will be replace by specified app project namespace. so, according to DRY(dont repeat yourself), i shouldn't just copy the file to many projects and rename the specified part manually. is there any way i can easily replace some parts of my template file to something related to the project?

• Problem with importing an mdf created with SQL Server Express 2008 into SQL Server 2005

  - by user252160

  The question is probably extremely easy to resolve, but I need to resolve it because I need to carry on with my project. I am using SQL Server Express 2008 at home, and I've been working on an ASP.NET MVC app that stores my DB in an mdf file in the project's folder. The problem is that the SQL Server in the Uni labs is SQL Server 2005, and when I try to open the mdf file with the VS Server Explorer,It says that the version of the mdf file is more than the server can accept. The only option that comes to my mind is exporting the DB as an sql file, just like I've done it thousand times with phpmyadmin. the thing is that the SQL Management Studio Express is not the most usable tool in the world, and for some strange reason all the articles I could find in Google were irrelevant. Please, help.

• Remove all html tags from attributes in rails

  - by Hock

  I have a Project model and it has some text attributes, one is summary. I have some projects that have html tags in the summary and I want to convert that to plain text. I have this method that has a regex that will remove all html tags. def strip_html_comments_on_data self.attributes.each{|key,value| value.to_s.gsub!(/(<[^>]+>|&nbsp;|\r|\n)/,"")} end I also have a before_save filter before_save :strip_html_comments_on_data The problem is that the html tags are still there after saving the project. What am I missing? And, is there a really easy way to have that method called in all the models? Thanks, Nicolás Hock Isaza

• Dynamic Data Associate Related Table Value?

  - by davemackey

  I have create a LINQ-to-SQL project in Visual Studio 2010 using Dynamic Data. In this project I have two tables. One is called phones_extension and the other phones_ten. The list of columns in phones_extension looks like this: id, extension, prefix, did_flag, len, ten_id, restriction_class_id, sfc_id, name_display, building_id, floor, room, phone_id, department_id In phones_ten it looks like this: id, name, pbxid Now, I'd like to be able to somehow make it so that there is an association (or inheritance?) that essentially results in me being able to make a query like phones_extension.ten and it gives me the result of phones_ten.name. Right now I have to get phones_extension.ten_id and then match that against phones_ten.id - I'm trying to get the DBML to handle this translation automatically. Is this possible?

• How to compress CSS/JS in VS2010 Web Deployment Build Template?

  - by RPM1984

  Hi all, We've recently upgraded from VS2008 - VS2010 (and hence upgrading from Web Deployment Project to proper deployment project). Obviously what's new in VS2010 web deployments is the introduction of Workflow as the build process template. Previously, we used a MSBuild task in the WDP to execute the Yahoo YUI Javascript/CSS compression module to minify/compress javascript and css files. Has anyone managed to accomplish this task with Visual Studio 2010? I have seen the new "SquishIt" compressor created by Justin Etheridge, but its not ideal as it "squishes" on the fly (e.g on Application_Start - Global.ascx) - which means you still have to push out all the uncompressed files to your web server before squishing. In the Workflow designer - i can see a toolbox item called "MSBuild" - just dont know how to use it to accomplish what i want. Been searching high and wide, no-one seems to know how. Surely someone out there has done this.

• Recommendations on resolving a cs1705 error

  - by Scott A. Lawrence

  I'm upgrading a number of solutions from Visual Studio 2008 to Visual Studio 2010RC. In the process of doing this, I've encountered two instances of compiler error cs1705, one for System.Core and another for System.Data.Linq. In each case, an assembly compiled earlier has a reference to the .NET 4.0 version of these system assemblies, while the web project I'm trying to compile only has references to the .NET 3.5 version of them. Adding .NET 4.0 versions of System.Core and System.Data.Linq to the web project doesn't resolve the error. Removing the .NET 3.5 versions of the assemblies so that only the .NET 4.0 versions remain results in even more errors. Any recommendations on how to resolve this error would be greatly appreciated.

• How can I convert .eps files to .jpg in ASP.NET?

  - by Mike C

  I am trying to convert uploaded .eps files to .jpg in my ASP.net application and I am having a hard time finding a .net library that will let me do this. I have tried using the ImageMagick libraries, but I don't have root access to the server in order to install the standard binaries, or run the command line executables. I have also tried the slightly modified project from CodeProject, but it was designed in VS2005 and I have VS2008 and 2010 and I think I run into some compatibility issues while trying to compile and execute the project. Is there a simpler solution available that just works natively in .NET? Thanks, Mike

• JMF Registry could not add item (Vista)

  - by Ranch

  Hello, I'm using JMF to capture video stream (webcam) on my Java project. The camera I'm using is recognized by JMF (JFMStudio) and I manage to get the video stream. However, on JMF Registry Editor - there's a list of available capture devices, when I click "Add" on one of the items (including the one I need) I get a "Could not add item" error. Therefore this camera is not set in the registry of it (god know where) and later on it is not recognized by my project: RGBFormat fmt = new RGBFormat(); // could be YUV - doesn't matter Vector v = CaptureDeviceManager.getDeviceList(fmt); v is empty (while I know the video source is recognized by Java , since I manage to get video on JMF Studio). Now, this happens only on Vista (where else) and not on XP. I have a suspiction that somehow Vista security blocks Java from writing the registry file, but of course, I might be wrong. One more comments: this is vfw:Microsoft WDM Image Capture(Win32):0 device. Any idea ?

• iphone problem - UIKit precompile error

  - by tigermain

  I've been working on a project for a few weeks now and today is the last day before it goes to client (typical). For some reason Im suddenly getting the following error when building my project (sim or device), even though other projects build fine /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator3.1.3.sdk/System/Library/Frameworks/UIKit.framework/Headers/UIKit.h:61:42: error: UIKit/UIVideoEditorController.h: No such file or directory The last thing I was trying to do was use the UIMessage framework for email, but I have stripped that out!?!? N.B I have checked and the .h file does appear to be in the same folder as the UIKit.h file

• Zend Studio Intellisense + zend Framework

  - by Ilya Biryukov

  Hi. I've got a very annoying problem with my Zend studio. I have a zend framework project I am working on. The actual zend framework code is inside my project (in library folder) and then ZS seems to reference to its own version of zend framework. As the result, I get 2 versions of the same function/class in my intellisense which is annoying to say the least. Today I had the last drop of patience with zend studio when I showed 4 copies of the same class (imagine what's its like looking at a large namespace times 4!). So, how do I remove all references inside ZS to its own version of ZF? Thanks!

• Eclipse: What is the minimum Eclipse installation needed for a headless PDE build?

  - by Christoph

  Hi, I am currently using PDE build in headless mode to build my OSGI Bundle project. The PDE Antrunner task uses an Eclipse installation and I am just pointing it to my local Eclipse installation. unfortunatelly my eclipse installation is about 260MB big, but I assume that a PDE build does NOT require all of those plugins in a standard eclipse installation. Does anyone now what is the minimum list of plugins I need for doing a headless PDE build? All of my dependencies I actually have in a custom target platform folder, so I guess the only thing I need from my eclipse installation are the dependencies which PDE build actually needs. But what are those? Can I shrink my installation to a very minimum? My goal is to also check-in this "build-eclipse" folder into my project's SVN so that when you check it out, you have everything you need to start a full build, without touching any build.properties. But I don't want to commit 266MB of eclipse if I maybe need only 20MB of it. Thanks Christoph

• How do I create sub-applications in Django?

  - by jamida

  I'm a Django newbie, but fairly experienced at programming. I have a set of related applications that I'd like to group into a sub-application but can not figure out how to get manage.py to do this for me. Ideally I'll end up with a structure like: project/ app/ subapp1/ subapp2/ I've tried: manage.py startapp app.subapp1 manage.py startapp app/subapp1 but this tells me that / and . are invalid characters for app names I've tried changing into the app directory and running ../manage.py subapp1 but that makes supapp1 at the top level. NOTE, I'm not trying to directly make a stand-alone application. I'm trying to do all this from within a project.

• GetWindowPlacement/SetWindowPlacement not working in WinForms for high DPI

  - by RandomEngy

  I've got a legacy WinForms app and I want to save the window position and size across sessions. I've been using GetWindowPlacement and SetWindowPlacement during the FormClosing and Load events. The problem I'm getting is that at higher DPI settings (Such as Medium, size at 125%) the sizes keep inflating. I'll call SetWindowPlacement on it with a certain size, but when GetWindowPlacement is called, those numbers come back 25% bigger, even though the window was the same size all along. The same sort of problem exists when saving the size of a resizable element within the form. Now this works fine if I create a new WinForms project: The size stays stable even when running at the higher DPI. I'm guessing there's some legacy setting in the bowels of the project or some arcane Form setting that's messing it up, but I can't find out where. I've called IsProcessDPIAware on both projects and both are true. Does anyone know what might be causing this?

• ADO.NET Entity Framework or ADO.NET

  - by sharru

  I'm starting a new project based on ASP.NET and Windows server. The application is planned to be pretty big and serve large amount of clients pulling and updating high freq. changing data. I have previously created projects with Linq-To-Sql or with Ado.Net. My plan for this project is to use VS2010 and the new EF4 framework. It would be great to hear other programmers options about development with Entity Framework Pros and cons from previous experience? Do you think EF4 is ready for production? Should i take the risk or just stick with plain old good ADO.NET?

• How do you install Castle Windsor IOC?

  - by user300266

  I'm currently reading Pro ASP.NET MVC Framework by Sanderson. In the book he recommends setting up IoC using Castle Windsor, and he points out that the download automatically installs it and registers the Castle DLLs in the GAC. Well, at this point in time (5/4/2010), the Castle Project no longer has a downloadable installer that sets this up. Its all broken out into their individual subprojects with the raw files contained in zipped folders. Sadly there's no installation documentation that I can find about how to set it up. Being the noob that I am, I'm stuck and now forced to ask #1 where should castle windsor live on my hard drive? #2 how do I manually register the dlls properly? And, #3 should I be angry at the project maintainers for their oversight? Here's the link: http://www.castleproject.org/castle/download.html

• Linking with Boost error

However, when I build the program, I get this linker error: LINK : fatal error LNK1104: cannot open file 'libboost_program_options-vc90-mt-gd-1_42.lib' The build log adds this (I've replaced project-specific paths with *'s): Creating temporary file "******\Debug\RSP00001252363252.rsp" with contents [ /OUT:"*********.exe" /INCREMENTAL /LIBPATH:"C:\Program Files\boost\boost_1_42_0\lib" /MANIFEST /MANIFESTFILE:"Debug\hw6.exe.intermediate.manifest" /MANIFESTUAC:"level='asInvoker' uiAccess='false'" /DEBUG /PDB:"********\Debug\***.pdb" /SUBSYSTEM:CONSOLE /DYNAMICBASE /NXCOMPAT /MACHINE:X86 kernel32.lib user32.lib gdi32.lib winspool.lib comdlg32.lib advapi32.lib shell32.lib ole32.lib oleaut32.lib uuid.lib odbc32.lib odbccp32.lib ".\Debug\****.obj" ".\Debug\****.exe.embed.manifest.res" ] Creating command line "link.exe @********\Debug\RSP00001252363252.rsp /NOLOGO /ERRORREPORT:PROMPT" I've also emailed [email protected] (with a message very similar to this), but I thought maybe so would be faster.
