• Intellisense in App_Code in VS2010

  - by nikok

  Hi, I've just upgrade my web application from vs2008 to vs2010, I create a new web app from vs2010, then copy across all the existing files from vs2008, then I add a new class file to App_Code folder, the intellisense is not showing up for everything and class etc is also not color in the right color. However, when I open the existing class I created earlier from vs2008, intellisense just working fine and all classes are in different color as well, if I make a copy of existing class, the copied class does not support the intellisense as well. However, if I shut my VS, and reopen it, they all appear to be support with intellisense for existing class, but once I created a new class, intellisense is not support. Can you tell me what's wrong here? Thanks

• Gap after table in LaTex

  - by Tim

  Hi, I notice that there is some gap after my table. See the following snapshot: http://i42.tinypic.com/23rkdn6.jpg My Latex code is: \begin{table}[htb] \caption{Error rates VS training size in AdaBoosted stump, SVM and kNN. \label{tab:examplecount8000errerrplot}} \begin{center} \begin{tabular}{c c} \includegraphics[scale=0.4]{../boost.eps} & \includegraphics[scale=0.4]{../svm.eps} \\ \includegraphics[scale=0.4]{../knn.eps} & \\ \end{tabular} \end{center} \end{table} % \subsection{Feature Numbers} Is the gap normal or How can I reduce the gap to be normal? Thanks and regards!

• Microsoft.SqlServer.SqlTools.VSIntegration reference problem/oddities in Visual Studio 2010

  - by Sung Meister

  SQL Server Edition: 2008 Enterprise Visual Studio: 2010 w/ .NET 4.0 SSMS 2008 Addin - Data Scripter project source code on CodePlex references Microsoft.SqlServer.SqlTools.VSIntegration.dll I have referenced the DLL under <<Microsoft SQL Server install location>>\100\Tools\Binn\VSShell\Common7\IDE But here is the oddity. Microsoft.SqlServer.SqlTools.VSIntegration.dll contains a namespace Microsoft.SqlServer.Management.UI.VSIntegration, which in turn contains ServiceCache (public sealed). As soon as I add the reference, ServiceCache is highlighted (meaning there is no reference issue) But the problem arises when I compile the project and VS 2010 throws up an error that it cannot find ServiceCache. The name 'ServiceCache' does not exist in the current context Why is that ServiceCache is not visible during compile time but looks like it's available right after adding the assembly? And Reflector does show that ServiceCache is part of the assembly that the project is referencing, but Visual Studio intellisense fails to display it. Any had this kind of problem? [UPDATE] Some screenshots Reflector clearly shows ServiceCache But Visual Studio 2010 says, otherwise...

• Visual C# GUI Designer basic tutorial

  - by cusack

  Hi, can you recommend a Visual C# Form Designer tutorial that is targeted at experienced programmers who have at least a basic knowledge of C# but are new to the VS C# Form Designer. At least it shouldn't be targeted at programming newbs, like Introduction to Visual C# 2008 Express Edition (it explains how a comment looks like in C#). So far I've found C# Programming Tutorial - Programming Winforms in C# on stackoverflow. Wishlist: ;-) I'm more interested in focus on the designer itself rather than an explanation of single gui-elements. In other words explaining separation between generated-code, what to not edit manually (visual-c#-designer-responsibility) and on the other hand the parts for which the programmer himself is responsible. So a little more abstract best-practice point of view pointing out some caveats would be great as well. I would prefer text over video as well, but that's minor. /Wishlist Perhaps even a Microsoft reference specific to the Visual c# forms designer (which I seem to have been unable to find) would be helpful.

• jquery json null when using localhost

  - by Eeyore

  I am trying to load json generated by my django app. It works when I save the json output and load it from a static file. However, when I make a call to a server it returns null. JSON {"users": [ { "id": 1, "name": "arnold" }, { "id": 2, "name": "frankie" } ]} Ajax call $.ajax({ url: "http://localhost:8000/json", //vs. json.js dataType: 'json', type: 'get', timeout: 20000, error: function() { alert("error"); }, beforeSend: function() { alert("beforeSend"); }, complete: function() { alert("complete"); }, success: function(data) { alert(data.users[0].name); } }); view.py return HttpResponse(simplejson.dumps(data), content_type = 'application/json; charset=utf8')

• How to write this in different regex flavours

  - by taspeotis

  I have the following data: a b c d FROM:<uniquepattern1> e f g h TO:<uniquepattern2> i j k l FROM:<uniquepattern1> m n o p TO:<uniquepattern3> q r s t FROM:<uniquepattern4> u v w x TO:<uniquepattern5> I would like a regex query that can find the contents of TO: when FROM:<uniquepattern1> is encountered, so the results would be uniquepattern2 and uniquepattern3. I am hopeless with regex, I would appreciate any pointers on how to write this (lookahead parameters?) and any differences between regex on different platforms (eg the C# .NET Regex versus Grep vs Perl) that might be relevant here. Thank you.

• How can I exceed the 60% Memory Limit of IIS7 in ASP.NET Caching application

  - by evilknot

  Pardon if this is more serverfault vs. stackoverflow. It seems to be on the border. We have an application that caches a large amount of product data for an e-commerce application using ASP.NET caching. This is a dictionary object with 65K elements, and our calculations put the object's size at ~10GB. Problem: The amount of memory the object consumes seems to be far in excess of our 10GB calculation. BIGGEST CONCERN: We can't seem to use over 60% of the 32GB in the server. What we've tried so far: In machine.config/system.web (sf doesn't allow the tags, pardon the formatting): processModel autoConfig="true" memoryLimit="80" In web.config/system.web/caching/cache (sf doesn't allow the tags, pardon the formatting): privateBytesLimit = "20000000000" (and 0, the default of course) percentagePhysicalMemoryUsedLimit = "90" Environment: Windows 2008R2 x64 32GB RAM IIS7 Nothing seems to allow us to exceed the 60% value. See screenshot of taskman. http://www.freeimagehosting.net/image.php?7a42144e03.jpg

• Building Visual studio like application, need inputs..

  - by akjoshi

  Hi, I am working on a Visual studio like application i.e. hava a tolbox, an editor and property grid similar to VS. ser can drag and drop the controls(custom and third party) to the editor window and perform operations like resize, move, align, group etc.; Properties of that control needs to be displayed in property grid and user can update them from there. As per my current understanding I will have to extend the Canvas to create my own editor and and Interface for controls which it supports; Each supported control will have to implemnt this interface so that it can be placed in our editor. Something similar to this - http://www.codeproject.com/KB/WPF/WPFDiagramDesigner_Part4.aspx Looking forward for any kind of help, comment or links.

• Why do Programmers Love/Hate Objective-C?

  - by Genericrich

  So I have noticed that there is a lot of animosity towards Objective-C among programmers. What's your take? Is it a vendor lock-in thing against Apple? General antipathy towards Apple? The syntax? What's your view on this? With the advent of the iPhone SDK, Obj-C has gotten a lot more attention lately, and I am curious what people on SO's opinions are. I personally fought the syntax at first but have gotten more and more used to it now. I really like the named arguments. I have some pet peeves with how things are done in Obj-C vs other languages, but I will refrain from comment on them here.

• C# 2008 Express v C# 2010 Express

  - by Andy

  Can anybody post a link to a comparison chart, or even to a duplicated question here on SO, for these two products? Plenty of info on what is missing between Express and Pro for example, but I'm struggling to find much on Express v Express. Is the only real difference the ability to develop apps for .NET 4.0? I'm developing WinForms apps, targetting .NET 2.0 at the moment, so are there any benefits for me in changing to 2010 Express? Unfortunately, upgrading to VS Professional or such is not an option for me right now, so I'm stuck with the hamstrung versions. Thanks.

• How do I use test/beta Perl modules from test Perl scripts?

  - by DVK

  If my Perl code has a production code location and "beta" code location (e.g. production Perl code us in /usr/code/scripts, BETA Perl code is in /usr/code/beta/scripts; production Perl libraries are in /usr/code/lib/perl and BETA versions of those libraries are in /usr/code/beta/lib/perl, is there an easy way for me to achieve such a setup? The exact requirements are: The code must be THE SAME in production and BETA location. To clarify, to promote any code (library or script) from BETA to production, the ONLY thing which needs to happen is literally issuing cp command from BETA to prod location - both the file name AND file contents must remain identical. BETA versions of scripts must call other BETA scripts and BETA libraries (if exist) or production libraries (if BETA libraries do not exist) The code paths must be the same between BETA and production with the exception of base directory (/usr/code/ vs /usr/code/beta/) I will present how we solved the problem as an answer to this question, but I'd like to know if there's a better way.

• How to read in text from the visual studio debug output window

  - by Jeremy Bell

  I've read several articles that tell you how to add text to the output window in visual studio from within an Add-On (specifically, a visual studio 2008 integration package, via the visual studio 2008 SDK 1.1), but no examples of how to read text from the output window. My goal is to parse text from the debug output window while debugging a certain application (TRACE output and possibly stdin/stdout). The IVsOutputWindowPane interface has no methods for reading in text from the output window. The documentation seems to imply that it is possible, but it doesn't provide an example: http://msdn.microsoft.com/en-us/library/bb166236(VS.80).aspx Quote: In addition, the OutputWindow and OutputWindowPane objects add some higher-level functionality to make it easier to enumerate the Output window panes and to retrieve text from the panes. Preferably I'd like to be able to subscribe to an event that fires when a new line of text arrives, similar to a StreamReader's asynchronous reads.

• .NET Framework 4 RTM on Windows server 2008 R2

  - by mare

  I've just installed .NET 4 on Windows SErver 2008 R2 x64 and I am getting 500 Internal Server Error with an ASP.NET MVC application which was previously running fine on 3.5. The application was upgraded from targeting 3.5 to target 4 and I personally built it today on my development machine (changed in VS - Properties to .NET Framework 4). On the server I installed .NET Framework 4 Client profile and Full both automatically through the Web Platform Installer. ASP.NET MVC 2 was also installed through Platform Installer. I created a new .NET 4 application pool in IIS and placed the web app in it. Also I have custom errors turned Off in web.config but even so no detailed error is displayed - just the plain IIS 7.5 500 Internal Server Error. Any suggestions?

• MagicLibrary.dll 32bit convert for 64bit

  - by Nullstr1ng

  Hi Guys, I recently received an email about a guy who like to make my software compatible with 64Bit Windows 7 OS. I have 1 single problem though .. I have followed a steps regarding on compiling VS Solution/Project for 64bit. But when I start to to compile the solution for 64bit, this "Crownwood.Magic.Forms" (MagicLibrary.dll) doesn't work anymore. This is the compilation error message "Error 6 The type or namespace name 'Crownwood' could not be found (are you missing a using directive or an assembly reference?)" Please don't tell me I did not referenced the MagicLibrary.dll It's a bit of confusing because the MagicLibrary.dll is already in my reference list. I also remove and add it back. There was this CorFlags.exe but am not sure how to convert it to 64bit. "CorFlags MagicLibrary.dll /32BIT- /Force" did not work.. :( Please help. Thanks in advance - Jayson

• How can I use Moose with Test::Class?

  - by rassie

  I'm currently refactoring a test suite built up by a colleague and would like to use Test::Class[::Most] while doing so. As I started I figured out I could really use a couple of Moose roles to decouple code a little bit. However, it seems it's not quite possible -- I'm getting error messages like this one: Prototype mismatch: sub My::Test::Class::Base::blessed: none vs ($) at /usr/lib/perl5/vendor_perl/5.8.8/Sub/Exporter.pm line 896 So the question is: can I use Moose together with Test::Class and if so, how? PS: The code goes like this: package My::Test::Class::Base; use Moose; use Test::Class::Most; with 'My::Cool::Role'; has attr => ( ... );

• HowTo set Icon to Qt Application, created with Qt Visual Studio Add-in?

  - by mosg

  Hello. Here is what I have: Visual Studio 2008 (on 32-bit Windows XP) Qt libraries 4.6.2 for Windows (VS 2008, 194 MB) Visual Studio Add-in (44 MB) After I installed all the software, I created simple Qt Application project, with Visual Studio: menu File | New | Project... and Qt4 Projects | Qt Application. Build it, and here is the question: how to set application icon to my compiled exe file? I need to see specified ICO in explorer! Old method with MyProject.pro not interested!!! Create a .ico file with both 16x16 and 32x32-pixel versions of the icon (you can do this in Visual Studio). Create a .rc file containing the following text: IDI_ICON1 ICON DISCARDABLE "myIcon.ico" Add the following to your .pro file RC_FILE = myFile.rc Run qmake. Thanks.

• Postgresql - one database for everyone, or one-database per customer

  - by user337876

  I'm working on a web-based business application where each customer will need to have their own data (think basecamphq.com type model) For scalability and ease-of-upgrades, I'd prefer to have a single database where each customer gets a filtered version of the data. The problem is how to guarantee that they stay sandboxed to their own data. Trying to enforce it in code seems like a disaster waiting to happen. I know Oracle has a way to append a where clause to every query based on a login id, but does Postgresql have anything similar? If not, is there a different design pattern I could use (like creating a view of each table for each customer that filters)? Worse case scenario, what is the performance/memory overhead of having 1000 100M databases vs having a single 1Tb database? I will need to provide backup/restore functionality on a per-customer basis which is dead-simple on a single database but quite a bit trickier if they are sharing the database with other customers.

• PowerPoint version compilation

  - by Jeremy A

  Let's say I am using SharpDevelop/VS to develop an app that uses PowerPoint. Do I need to recompile the app so there is a build for each version of MS Office? I have MS Office 2007, but I would also like the app to work with Office 2003 and later, without having to recompile the app for each version. Do I just need to install the appropriate Office Interop redistributable package/msi on the client machine, and ship my app as is? Thanks in advance for your help.

• Unable to load DLL 'foo.dll', but only when running through vhost

  - by biozinc

  This is a variation on the old System.DllNotFoundException: Unable to load DLL 'foo.dll': The specified module could not be found. (Exception from HRESULT: 0x8007007E). problem (where, of course, foo.dll is the name of an actual DLL). The strange part is that I only get this error when I "Run" in VS (2008 if that's relevant). That sits in the MyApp.vhost.exe processes. If I run the actual app in a command line (MyApp.exe) I encounter no errors. The problem extends to unit tests with MSTest. A check on the DLL with DependencyWalker on Foo.dll doesn't show any issues. Any ideas?

• Is there a default buffer length for 'sprintf' method?

  - by Isuru

  Hi, I used sprintf method to format data to a string which I want to write to a file, in C++ console application using VS 2008. The Input is a particular message, which has various variables and values (ex: Type 'int' and Value '10' / Type string and value "abc", etc.) When I send a two messages it works perfectly. But When I send more than two messages it gives a runtime error saying 0xC0000005: Access violation reading location 0xabababab. Why is this happening? Is it because the method 'sprintf' has a default buffer length? How can I overcome this problem?

• Debugging Visual Studio 2010 Unit Test and WCF Service in one IDE instance

  - by Dr.HappyPants

  I have created a WCF service in Visual Studio 2010 along with some supporting assemblies. I have also created a test project which contains multiple unit tests for the service and the supporting assemblies. Right now I have them all in one solution with the Test project having a service reference (http) to the WCF service. If I debug the WCF service and select "Run checked tests" in a Test List I created, I can debug the WCF service without a problem. Note: I cannot select Debug Checked Tests while debugging the WCF service. (Because the IDE is already debugging?) If I open the Test project in another instance of VS 2010, debug the WCF service and then select "Debug Checked Tests" - I can debug both my tests and the WCF service. However - I would like to (and my question is) be able to debug my tests and my service in a single IDE. Is this possible?

• How to generate proxy for a child class when my web service return a parent class?

  - by Amir Borzoei

  Hi * I have a web method like this: public class ParentClass{ public String str1; } public class ChildClass : ParentClass{ public String str2; } public class WebService{ public ParentClass WebMethod(){ return GetFirstChildClass(); //Return a child class } } When I generate proxy for this web service by Visual Studio, VS just generate proxy for ParentClass but I need ChildClass too. For workaround I add a dummy method to WebService that return ChildClass to generate proxy for ChildClass in client. public class WebService{ ... //This is a dummy method to generate proxy for ChildClass in client. public ChildClass DummyWebMethod(){ return null; } } In addition I write web service in java (JAX-WS) and my client is a SilverLight Application. Is there a better solution for this problem? tanx for your help ;)

• Running Visual Studio 2005, 2008, and 2010 on same system.

  I have around 50 projects in Visual Studio 2005 that I am building a new development machine for and I'd like to slowly move those projects to VS 2008 but also have 2010 available for select new projects. Can this work? Are there any gotchas for this sort of setup? Any general advice for running multiple versions of Visual Studio on the same system would be greatly appreciated. Specifically related to managing a controlled migration of projects to new versions but being able to selectively keep some on old versions.

• How to Track F5/Refresh in ASP.Net

  - by Everest

  I am using VS 2005, C# 2, ASP.Net 2.0 I am unable to find out how to track that user pressed F5/Ctrl+F5/ Open a new Window(Ctrl + N) in ASP.Net. I know that there is a Page.IsPostBack property, which tells that a page is loaded in response to an action taken by user. I am just curious to know, that why isn't there a property as IsRefresh or Page.IsRefresh in ASP.Net, which will return true, whenever user takes any of the above actions. Is there a way to know this? Actually my problem is that i have a DLL using which all of my aspx pages are inherited, I have to insert some values in a table whenever the page is opened for the first time that's it, if user just opens the page or do not take any action, an entry should be inserted into the database, but as far as I have tried, I controlled it anyhow using the Page.IsPostBack property, but I got stuck in the refresh case, as it is inserting records unconditionally.
