• Change webserver used by Flex in FlexBuilder to .NET Framework 3.5

  - by Simon_Weaver

  I just had to reformat and reinstall Flex and reconstruct a project. The problem is i am using ASP.NET as my server side technology and using LINQ in my files. The version of WebDev.Webserver.exe that FlexBuilder starts up is the wrong version so I get this error : Compiler Error Message: CS0234: The type or namespace name 'Linq' does not exist in the namespace 'System' (are you missing an assembly reference?) Microsoft (R) Visual C# 2005 Compiler version 8.00.50727.3053 for Microsoft (R) Windows (R) 2005 Framework version 2.0.50727 Copyright (C) Microsoft Corporation 2001-2005. All rights reserved. I know that changing to the latest version of ASP.NET / Framework will fix this - but I just can't figure out HOW to make that change in Flexbuilder. I cant even remember if i ever successfully did it before or if I just created a virtual directory in IIS7. Where would I change the version?

• using BOOST_FOREACH with std::map

  - by kmote

  I'd like to iterate over a std::map using BOOST_FOREACH and edit the values. I can't quite get it. typedef std::pair<int, int> IdSizePair_t; std::map<int,int> mmap; mmap[1] = 1; mmap[2] = 2; mmap[3] = 3; BOOST_FOREACH( IdSizePair_t i, mmap ) i.second++; // mmap should contain {2,3,4} here Of course this doesn't change anything because I'm not iterating by reference. So I substitute this line instead (as per the example in the Boost docs): BOOST_FOREACH( IdSizePair_t &i, mmap ) and I get the compiler error: error C2440: 'initializing' : cannot convert from 'std::pair<_Ty1,_Ty2>' to 'IdSizePair_t &' with [ _Ty1=const int, _Ty2=int ] Any suggestions?

• ASP.Net error: “The type ‘foo’ exists in both ”temp1.dll“ and ”temp2.dll" (pt 2)

  - by Greg

  I'm experiencing the same problem as in this question, but none of the answers fixed my problem. (edit: Setting the web.config batch attribute works, but that's a coverup, not a solution) The problem I'm having is with a User Control that I moved from the root directory to a subdirectory within the same Web Application project. It used to work fine before I moved it. When I moved it it started giving me the error message. It's saying that the class name exists in two dll files in Temporary ASP.NET Files. Sure enough, when I open Reflector, it's in two dlls. If I rename the class and ascx file, everything works fine. No usages of the original name exist within any of the files in my entire application. When I rename the file, I opened all of the dll files in Temporary ASP.NET Files with Reflector, and no references to the original class name exists. So where's this phantom reference coming from how can I fix this?

Any jquery plugin for implementing Masked Input.

• Map external directory to web.xml

  - by prometheus

  Is there an easy way to map a directory in the web.xml or other deployment descriptor (jetty.xml, etc) files? For example, if I have a directory /opt/files/ is there a way that I can access its files and sub-directories by visiting http://localhost/some-mapping/? It strikes me that there should be some simple way of doing this, but I haven't been able to find out how (via google, stackoverflow, etc). All I've found are servlets that mimic fileservers, which is not what I would like. For reference I am using jetty on an AIX box.

• ADO.NET Entity Framework with OLE DB Access Data Source

  - by Tim Long

  Has anyone found a way to make the ADO.NET Entity Framework work with OLE DB or ODBC data sources? Specifically, I need to work with an Access database that for various reasons can't be upsized to SQL. This MSDN page says: The .NET Framework includes ADO.NET providers for direct access to Microsoft SQL Server (including Entity Framework support), and for indirect access to other databases with ODBC and OLE DB drivers (see .NET Framework Data Providers). For direct access to other databases, many third-party providers are available as shown below. The reference to "indirect access to other databases" is tantalising but I confess that I am hopelessly confused by all the different names for data access technology.

• ViewContext.RouteData.Values["action"] is null on server... works fine on local machine

  - by rksprst

  I'm having a weird issue where ViewContext.RouteData.Values["action"] is null on my staging server, but works fine on my dev machine (asp.net development server). The code is simple: public string CheckActiveClass(string actionName) { string text = ""; if (ViewContext.RouteData.Values["action"].ToString() == actionName) { text = "selected"; } return text; } I get the error on the ViewContext.RouteData.Values["action"] line. The error is: Exception Details: System.NullReferenceException: Object reference not set to an instance of an object. Any help is appreciated. Thanks in advance.

• How to ignore GUI as much as possible without rendering APP less GUI developer friendly

  - by pbernatchez

  The substance of an app is more important to me than its apperance, yet GUI always seems to dominate a disproportionate percentage of programmer time, development and target resource requirements/constraints. Ideally I'd like an application architecture that will permit me to develop an app using a lightweight reference GUI/kit and focus on non gui aspects to produce a quality app which is GUI enabled/friendly. I would want APP and the GUI to be sufficiently decoupled to maximize the ease for you GUI experts to plug the app into to some target GUI design/framework/context. e.g. targets such as: termcap GUI, web app GUI framework, desktop GUI, thin client GUI. In short: How do I mostly ignore the GUI, but avoid painting you into a corner when I don't even know who you are yet?

• WPF: OnRender and Hit Testing

  - by stefan.at.wpf

  Hello, when using OnRender to draw something on the screen, is there any way to perform Hit Testing on the drawn graphics? Sample Code protected override void OnRender(System.Windows.Media.DrawingContext drawingContext) { base.OnRender(drawingContext); drawingContext.DrawRectangle(Brushes.Black, null, new Rect(50, 50, 100, 100)); } Obviously one has no reference to the drawn Rectangle which would be necessary to perform hit testing or am I wrong about this? I know I can use DrawingVisual, I'm just curious if my understanding is correct, that using OnRender to draw something you can't perform any hit testing on the drawn things?

• boost spirit semantic action parameters

  - by lurscher

  Hi, in this article about boost spirit semantic actions it is mentioned that There are actually 2 more arguments being passed: the parser context and a reference to a boolean ‘hit’ parameter. The parser context is meaningful only if the semantic action is attached somewhere to the right hand side of a rule. We will see more information about this shortly. The boolean value can be set to false inside the semantic action invalidates the match in retrospective, making the parser fail. All fine, but i've been trying to find an example passing a function object as semantic action that uses the other parameters (parser context and hit boolean) but i haven't found any. I would love to see an example using regular functions or function objects, as i barely can grok the phoenix voodoo

  - by George2

  Hello everyone, I am using VSTS 2008 + C# + .Net 3.5 + Silverlight 3.0 + ASP.Net to develop a Silverlight application (a video media player) in browser and the function is simple, just use MediaElement to play a remote video file. The remote server is Windows Server 2008 + IIS 7.0 + IIS Media Bit Rate Throttling Control. Since the request media URL can be discovered (e.g. from traffic sniffer), and I want to know how to prevent from download directly from the Url? i.e. I want end user to use my Silverlight media player application in browser to play the file, prevent them from download to local directly. Any easy and quick solution or reference code/documents? thanks in advance, George

• Good book for THINKING in terms of algorithms?

  - by chrisgoyal

  Before you mark this is a duplicate, let me explain why this is different. Most of the books on algorithms are more of a reference. You basically have a list of algorithms at your disposal. But what happens when you need to create a new algorithm for something? These books don't teach how to think in terms of algorithms. So I'm looking for books that will teach me the thinking-process of creating algorithms. Any good suggestions?

• Privilege Elevation only when and if required.

  - by Cameron Peters

  My application only very occasionally requires privilege elevation... I need to reference some 3rd party COM components that only work correctly when run as administrator. I would like my application to request privilege elevation only when it needs it... Generally, I don't want my application to run as administrator unless I need to use the 3rd party COM components. I see that CoCreateAsAdmin could potentially solve the problem, but the component author doesn't set up the required registry entries, and I'm not sure how to use CoCreateAsAdmin in C# and in conjuction with Runtime-Callable-Wrapper that is created by tlbimp. Another solution would be to spawn another process, but I have no experience with this yet... I don't want to create a completely separate application... I would be happy to create an assembly that runs in a separated elevated process if someone can show me how to make it work. Thanks...

  Hi All, Ive only posted on here a couple of times and people have been very quick and very helpful when responding so thanks. Im trying to use the UIActionsheet element in my Ipad application. But just to confuse matters im using Cocos2d aswell. But here is my problem. If coding the actionsheet with out cocos2d you would use the following code.

But this is located in the appdelegate class. ive tried [actionSheet showInView:self.Window]; and i get errors any help?

• Best practice to calculate the average speed from GPS coordinates

  - by Sebi

  i have here a device which can give me gps coordinates. the time intervall i can define. i want to use it to calculate the average speed during driving or travelling by car. actually i used a orthodrome formula to calculate the distance between two points and then divided it by the given time intervall. by the implemenation i followed this term (http://de.wikipedia.org/wiki/Orthodrome#Genauere_Formel_zur_Abstandsberechnung_auf_der_Erde). Unfortunately i could only find a german link, but i think the formula should be understandable in any language ;) Unfortunately, using this formula and a time intverall of 1 seconds gives very unprecises results. the speed while walking is between 1 km/h and 20km/h. So i wonder if there is a general reference how to implement distance calculation between two gps coordinates (i found something similar on SO) and particulary, which is the best time intervall to update the GPS coordiantes.

• App.config connection string Protection error

  - by MikeScott8

  I am running into an issue I had before; can't find my reference on how to solve it. Here is the issue. We encrypt the connection strings section in the app.config for our client application using code below: config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None) If config.ConnectionStrings.SectionInformation.IsProtected = False Then config.ConnectionStrings.SectionInformation.ProtectSection(Nothing) ' We must save the changes to the configuration file.' config.Save(ConfigurationSaveMode.Modified, True) End If The issue is we had a salesperson leave. The old laptop is going to a new salesperson and under the new user's login, when it tries to to do this we get an error. The error is: Unhandled Exception: System.Configuration.ConfigurationErrorsException: An error occurred executing the configuration section handler for connectionStrings. ---> System.Configuration.ConfigurationErrorsException: Failed to encrypt the section 'connectionStrings' using provider 'RsaProtectedConfigurationProvider'. Error message from the provider: Object already exists. ---> System.Security.Cryptography.CryptographicException: Object already exists

• Nullable One To One Relationships with Integer Keys in LINQ-to-SQL

  - by Craig Walker

  I have two objects (Foo and Bar) that have a one-to-zero-or-one relationship between them. So, Foo has a nullable foreign key reference to Bar.ID and a (nullbusted) unique index to enforce the "1" side. Bar.ID is an int, and so Foo.BarID is a nullable int. The problem occurs in the LINQ-to-SQL DBML mapping of .NET types to SQL datatypes. Since int is not a nullable type in .NET, it gets wrapped in a Nullable<int>. However, this is not the same type as int, and so Visual Studio gives me this error message when I try to create the OneToOne Association between them: Cannot create an association "Bar_Foo". Properties do not have matching types: "ID", "BarID". Is there a way around this?

• NInject and thread-safety

  - by cbp

  I am having problems with the following class in a multi-threaded environment: public class Foo { [Inject] public IBar InjectedBar { get; set; } public bool NonInjectedProp { get; set; } public void DoSomething() { /* The following line is causing a null-reference exception */ InjectedBar.DoSomething(); } public Foo(bool nonInjectedProp) { /* This line should inject the InjectedBar property */ KernelContainer.Inject(this); NonInjectedProp = nonInjectedProp; } } This is a legacy class which is why I am using property rather than constructor injection. Sometime when the DoSomething() is called the InjectedBar property is null. In a single-threaded application, everything runs fine. How can this be occuring and how can I prevent it?

  I have set up references to 2 web services in a separate assembly TestProj.Core. I reference this Project in a Web Application Project called TestProj.Web. When I setup the references in TestProj.Core the wizard gave me an app.config and through an application settings section into it. How do I get these settings to my web app? Copy and paste these into web.config? "Always Copy" the app.config out to the bin directory? Any good articles on mutiple configs?
