.net-4.0

问题 I have problem with deploying my website to a server (which is not mine). I have one application that is running on this server and it is working (mvc 3, EF4). It was some time ago so I don´t know exactly what I changed to run it on that server but I think it was just adding referencies to bin folder. Now when I am trying on same server run my second app I did what is here: http://midnightprogrammer.net/post/Bin-Deploy-ASPNET-MVC-3-Application-With-SQL-CE-40-Entity-Framework.aspx and It says

问题 What I want is somewhat similar to what happens in a WinForm designer in Visual Studio, say VS2010. If I place a button and select it and use arrow keys, it will move around by 5 pixels in whatever direction I chose by pressing the right key. Now, if I hold either a Shift or a Ctrl modifier as I do that (forgot which one, sorry), then the button will move only by 1 pixel at a time. I want this to happen with my NumericUpDown control in a C# WinForm app. Let's say a default increment is 100.0,

问题 I tried creating an Azure project in Visual Studio 2012 Ultimate with a single MVC4 web role in it but got this error message. The project itself after creating didn't contain the MVC4 role I wanted. I only found similar error messages for MVC2 and on my other computer it works fine. 回答1: The roletemplatedata.xml file is a file included in each Windows Azure project in Visual Studio (ie: Web Roles with MVC3, MVC4, WCF, ...). You should be able to find it under C:\Program Files (x86)\Microsoft

问题 Is it possible to get IntrospectionExtensions for .NET 4.0. It is available by default in .NET 4.5, but for various reasons, I would like to use it in .NET 4.0. 回答1: Simply add the Mono source code to your project and compile it, https://github.com/mono/mono/blob/mono-4.0.2.4/mcs/class/corlib/System.Reflection/IntrospectionExtensions.cs#L40 Make sure you remove it once migrating to .NET 4.5 and above. 来源： https://stackoverflow.com/questions/22366976/system-reflection-introspectionextensions

问题 I'd like to update a view from another view via events. At the moment I have no idea how to do that?. My Case: I have a calculation engine, and when I perform the calculation, I want to inform the user about the performed steps. So I open a new window with a RichTextBox control to display the desired information.

I have installed the 3.5 and now i'm having problem with add .net 3.5 to the new visual studio. how can i add 3.5 to vs 2010? 回答1: You don't need to "add" .NET 3.5 to VS2010. When you create a new project, you just specify which version of .NET you want to target. (You can change this later, too, in project properties.) 回答2: Try this link: http://www.microsoft.com/downloads/en

问题 When trying to press the standard Windows 7 logoff button while my WPF app is running, I get "This program is preventing Windows from logging off". I would like to force it to close without having to press "Force log off". Similarly, pressing "End Task" in the (applications) Task Manager causes it to become non-responsive rather than just close the program. I have tried adding this to Window_Closing, but this doesn't seem to do it: private void Window_Closing(object sender, System

问题 Using SSIS, I Can use an OLE Connect with a Jet driver to read Excel or I can use a separate Connection type of "Excel Connection" Both seem to have issues reading files with merges cells, as I feared. I am curious what SSIS is using to connect to Excel when an "Excel Connection" is used. Other than VBA, what would you suggest for reading an Excel file that has merged cells, formulas, formatting, etc, on a server? I am using Excel 2003. Update Here's the code that I use to read the XLS:
