.net-3.5

问题 I just finished building my new COM project (C#, .NET 3.5). This project will be called by a VFP application. It's working great on my development machine, but now I need to know how to deploy it on the user's machine. Click Once isn't available for this kind of project, so I guess I'm stuck with manually distributing the DLL. So, where should I put the DLL and how do I register it? BTW, the 3.5 framework is already installed on the user's machine. TIA 回答1: I've really never used RegSvr32

SampleContext sc = new SampleContext(); sc.TableA.MergeOption = MergeOption.NoTracking; sc.TableB

问题 I am going to develop a new website with asp.net 3.5 and LinqToSQL. For maintainability purposes, how can I modify a Linq class if an attribute is added to a table in the database ? Thank you. 回答1: Unfortunately LinqToSQL does not have synchronization support in Visual Studio. The options are: Remove the table and add it again. Of course any customization changes are lost Edit the .dbml file file directly and add the attribute. The file has xml content and when saving it will regenerate the

问题 I have a class that I need to do some custom XML output from, thus I implement the IXmlSerializable interface. However, some of the fields I want to output with the default serialization except I want to change the xml tag names. When I call serializer.Serialize, I get default tag names in the XML. Can I change these somehow? Here is my code: public class myClass: IXmlSerializable { //Some fields here that I do the custom serializing on ... // These fields I want the default serialization on

问题 I've got this to work using a very basic example(outlined below) and I want to see if other SOers have experience doing what I'm attempting...using a 3.5 framework assembly in a Script Task in SSIS 2005. I've basically followed the page found here... except I targeted the 3.5 framework while in Visual Studio 2008. Write/compile your code (targeted the 3.5 framework) Just some simple Linq so that I'm using a greater than 2.0 framework feature using System; using System.Collections.Generic;

问题 I am using C# .NET 3.5 Compact Framework to write code.. please can any one tell me how do i register a form for WM_DEVICECHANGE and how to handle that message in WindowProc .. if I do this I get intimation of device hardware change.. I m not getting how to write please tell. Thanks 回答1: The key is to create a class deriving from NativeWindow, give this the handle of your form to call AssignHandle with, and override the WndProc function (allowing you to do what you want with WM_DEVICECHANGE).
