  • Using MSpec runner in Visual Studio 2010 and .NET 4

    - by spapaseit
    Hi Everyone, I'm a big fan of MSpec so naturally I wanted to use is right away with VS2010 as well. I have the MSpec runner defined as an external tool in Visual Studio to be able to have it always visible as a toolbar item. Anyway, whenever I try to use the MSpec runner (mspec.exe) with a .NET 4.0 solution I get the following error: Could not load file or assembly 'file:///C:\Users\[SOMEUSER]\[SOME_FOLDERS}\bin\Debug\[PROJECT].Specs.dll' or one of its dependencies. This assembly is built by a runtime newer than the currently loaded runtime and cannot be loaded. I can still run my specs with the Resharper 5 runner so it's no big drama, but I bothers me to no end :þ Do you guys have any idea what the problem could be? Is there any solution other than recompiling the whole Mspec source code as a .NET 4.0 solution, which I really, really don't want to do? Thanks in advance. Sergi

  • Problem with datagridvieew in vb.net

    - by user225269
    I'm trying to add a datagridview in vb.net, but it does not allow me to change the connection string or the database that should be imported to connect to it. The only thing that I'm seeing is the previous ms sql database that I connected with datagridview and everytime I click the new connection, the window closes and it leaves me with the datagridview with the previous connection that I have. And its not applicable because, now I want to connect it with mysql. Not ms sql. Its some sort of a cache like feature in vb.net, how do I get rid of it. so that I can add the new connection for mysql? Do I need to reinstall visual studio 2008?

  • Lucene.NET - Find documents that do not contain a specified field

    - by Brandon
    Let's say I have 2 instance of a class called 'Animal'. Animal has 3 fields: Name, Age, and Type The name field is nullable, so before I insert an instance of Animal as a Lucene indexed document, I check if Animal.Name == null, and if it does, I do not insert it as a field in my document. If I were to retrieve all animals, I would see that the Name field does not exist and I can set its value to null. However, there may be situations where I want to say "Get me all animals that do not have a name specified yet." In this situation I want to retrieve all Lucene.NET documents from my animal index that do not contain the Name field. Is there an easy way to do this with Lucene.NET? I want to stay away from having to perform some sort of hack to check if my name field has a value of 'null'.

  • Where/When do C# and the .NET Framework fail to be the right tool?

    - by Nate Bross
    In my non-programming life, I always attempt to use the appropriate tool for the job, and I feel that I do the same in my programming life, but I find that I am choosing C# and .NET for almost everything. I'm finding it hard to come up with (realistic business) needs that cannot be met by .NET and C#. Obviously embedded systems might require something less bloated than the .NET Micro Framework, but I'm really looking for line of business type situations where .NET is not the best tool. I'm primarly a C# and .NET guy since its what I'm the most comfertable in, but I know a fair amount of C++, php, VB, PowerShell, batch files, and Java, as well as being versed in the web technologes (JavaScript, HTML, and CSS). But I'm open minded about it my skill set and I'm looking for cases where C# and .NET are not the right tool for the job. I choose .NET and C# because I'm comfortable with it, but I'm looking for cases where it isn't appropriate.

  • .NET Compact COM interoperability

    - by markhor
    I have the following code in a full .NET framework solution: public delegate int CreateObjectDelegate( [In] ref Guid classID, [In] ref Guid interfaceID, [MarshalAs(UnmanagedType.Interface)] out object outObject); ... var createObject = (NativeMethods.CreateObjectDelegate) Marshal.GetDelegateForFunctionPointer( NativeMethods.GetProcAddress(_modulePtr, "CreateObject"), typeof (NativeMethods.CreateObjectDelegate)); object result; Guid interfaceId = _guid; Guid classID = _classId; createObject(ref classID, ref interfaceId, out result); The purpose is to create the needed COM object at runtime. Is it possible with any .NET compact framework? Note that it doesn't have Marshal.GetDelegateForFunctionPointer.

  • Why can't I make an http request to the ASP.NET development server on localhost?

    - by Chris Farmer
    I have an ASP.NET project (VS2008 on Windows 7 with either webforms, MVC1, or MVC2 -- all the same result for me) which is just the File-New hello world web project. It's using the default ASP.NET development server, and when I start the server with F5, the browser never connects and I get a timeout. I tried to debug this by telnetting to the development server's port while it was running, and I got the same result: C:\Users\farmercs>telnet localhost 54752 Connecting To localhost...Could not open connection to the host, on port 54752: Connect failed I can see in the system tray that the server thinks it's running, and a netstat -s -n command shows that there is indeed an active TCP listener on that port. This worked in the not-too-distant past, and I could work on web projects using the development server. One thing that has changed since then was that I installed the Microsoft Loopback Adapter to accommodate a local development Oracle installation. I'm not sure this is the problem, but it seems a likely culprit. So, what could be blocking me from connecting? And if it's the loopback, then what is a good way for me to retain my ability to connect to my development Oracle server while still being able to use the ASP.NET development server?

  • ASP.net site looks completely different on IE, Firefox, and Chrome; why?

    - by DavidR
    I'm doing css for a website. I send the html and css to a guy, he puts it into ASP.net. The problem is that the transfer didn't end well for my code and it needs some fixing. The problem is that when I look at it in Chrome, or Firefox, or IE8, I get three completely different renderings. I spent a good amount of time trying to fix a drop-down menu that is supposed to appear while hovering over a link. The one he had in place from ASP.net worked in IE, kinda worked in Firefox, and was completely broken in Chrome (I haven't tested Safari or Opera.) Just getting it to look basically the same in firefox and chrome was a struggle. The html source is showing me two completely different pages as well. Does anyone have experience with this? I know nothing of ASP.net, and it seems like the guy is modifying my layout with a wsyiwyg (I found tables used in random places, which I did not put there.) Faced with this, what is my best option? Is this fixable, or am I in over my head?

  • Why did Steve Sanderson in his "Pro ASP.NET MVC 2 Framework" book change an example IoC container?

    - by rem
    I like Steve Sanderson's "Pro ASP.NET MVC Framework" book. It helped me a lot. I have been waiting for its new edition and it is ready now, as we can see in this Steve's blog post It is updated a lot taking into account all new features of ASP.NET MVC 2, .NET 4 and Visual Studio 2010. In addition, "SportsStore" tutorial of this edition uses Ninject instead of first edition's Castle Windsor for DI. I wonder, why? Does it mean that Castle Windsor became a little outdated?

  • Open Source 2D Game Engine that supports Hexagon Maps for .NET

    - by Fred F.
    Hello, I cannot find a 2D game engine to create hexagon maps for .net. The best I can find is Xconq (http://sourceforge.net/projects/xconq/) and pygame. Does anybody where I can find any? preferrably one like xconq. Thank you for your time and effort. I really apprecate it. Edit: I would like to have feature of a strategic nature. Like adding custom AIs, path finding, etc. Xcong is an engine for turn-based strategy games.

  • Confused with conditional and logical operators - VB.net

    - by AgentRev
    I'm kind of new to VB.net, and since I just finished a C# course, the lack of parentheses creates a lot of confusion on how to write certain combinations of operators. The C# equivalent of the line I am trying to reproduce in VB would be like this : if ( (a == 0 && b != null) || (a == 1 && c != null) ) I'm have no idea how to write this in VB, I've tried many combinations of And, Or, AndAlso, OrElse, etc. but I can't achieve the desired result. I can't find any clear example of C# v.s. VB.net comparison on operators, and the notes I have aren't helpful either. Can someone help me figure this out?

  • When radio button selection changes do not cause refresh?

    - by JPJedi
    When the selection of the radio buttons change I would like to show/hide the panel in the next table cell.

  • .net, using PowerShell class to invoke a "[namespace.class]::method" style command

    - by Marco
    Hello, I created a powershell object via .net to invoke commands. When I invoke normal commands like 'Get-Process' I had no problems: ps.AddCommand("Get-Process").AddParameter(...).Invoke() but I'm not able to invoke a .net method with the syntax "[namespace.class]::method", just to make an example to invoke [System.IO.File]::Exists("c:\boo.txt"). I tried with ps.AddCommand("[System.IO.File]::Exists(\"c:\boo.txt\")").Invoke() ps.AddCommand("[System.IO.File]::Exists").AddArgument("c:\boo.txt\").Invoke() and some others. It always throws an exception which says that the command specified is not recognized. There is a way to invoke that type of command? Thanks

  • Create slide-in notifications à la Outlook in Windows with .NET

    - by Draak
    I am using .NET and am creating a desktop app/service that will display notifications in the corner of my Desktop when certain events are triggered. I don't want to use a regular Message Box b/c that would be too intrusive. The notifications would slide into view and then fade out after a few seconds. I am thinking of something that will act very much like the Outlook alerts that one gets when a new message arrives. The question is: Should I use WPF for this? I've never done anything with WPF but will happily try it if that's best means to the end. Is there a way to accomplish this with regular .NET libraries?
