.net-4.0

问题 I have a small console application. It checks a few settings, makes some decisions, and sends an email. The problem is the email doesn't actually get sent until my application finishes. I want the email sent as soon as my method that sends the email completes. Initially, I just created a MailMessage and called .Send(). That's when I noticed the mail was not being sent until the app finished. Then I tried using the task parallel library. var taskA = Task.Factory.StartNew(() => msg.Send());

问题 The scenario is like this: I have a .NET 4.0 client-Server application that works fine. I need to create a UserControl that can access the Server, but it needs to be created in .NET 2.0 (because customer application is .NET 2.0) Does it exist a way to access .NET 4.0 WCF service from a 2.0 client? NOTE: it is not a Web service, but a standalone .exe server No autentication used Data transfered are almost basic (class with arrays and basic types within) it uses client callbacks so protocol il

问题 As per my other question UrlRewriter.NET with .NET 4.0 not working I was unable to get UrlRewriter.NET to work. So now I have tried ManagedFusion. It works locally but does not work on the server BUT the errors are different and I sense that this might actually work and I have done something wrong in the configuration. So my web.config settings are (condensed version) <configuration> <configSections> <section name="managedFusion.rewriter" type="ManagedFusion.Rewriter.Configuration

问题 See the Image below: Scenario I have a repeater control bearing Id " rpt1 " ,inside the ItemTemplate of which I have a span control whose Id is " abc ", which is currently displaying a number. I also have a ticker above the repeater in format dd-MM-yyyy hh:mm:ss (27-05-2013 11:24:36), made up of ASP:Timer and ASP:UpdatePanel . Requirement What i need is that whenever my second part of the timer reaches 00, I would like to change the content of span from number to some image. Code ASPX: <form

问题 I've been asked to export a list of users from ActiveDirectory, and Convert the GUIDs to a numeric equivalent for display (so I'll .ToString that after). I've done some searching but most of the questions are on converting something TO a GUID, or converting a GUID to Int or something silly, (I understand Ints are too small etc..), which arn't really appropriate. I have the AD stuff sorted and the data exported, however I'm wondering what data type / format to use to convert the GUIDs to, and

问题 I have a WPF Popup that has several controls in it. The user can tab through the controls just fine. But when the last control is reached, then tab will move the focus back to the first control in the Popup. Rather than cycle back to the start, I would like the Popup to close and have focus move to then next control in the Popup's parent. I have seen the KeyboardNavigation.TabNavigation options, but no matter what I set them to, the focus always cycles (or tabbing is disabled). Is there a way

问题 I have an ordered test that contains 4 web tests. The problem is that Visual Studio seems to have a problem loading the test results for an individual test. I included a screenshot to supplement for the 1000 words. :) As you may see the 3rd test, called intuitively Webservice03, failed. The screenshot above was taken after I double-clicked on the corresponding line to open the detailed information about that test run. The panels with requests and other useful information are empty. The issue

问题 There's some spacing between the Buttons I add to my TableLayoutPanel . I removed the border in the Button and set the Margin and Padding to 0 in the Panel. But I continue getting that spacing. tableLayoutPanel.RowCount is set to 8 and the Rows collection I've added 8 rows with Size Type Absolute . Am I missing something? Here's the code: private void FillSelectLayout() { tableLayoutPanelSelect.Controls.Clear(); tableLayoutPanelSelect.RowStyles.Clear(); tableLayoutPanelSelect.RowCount = 8;

问题 I am building an application that targets .Net 4.0 (cannot be higher for the moment). I need to get access to Oracle Db (11g) and I wanted to use Entity Framework. To be able to do that I know that I have to use: Oracle.ManagedDataAccess Oracle.ManagedDataAccess.EntityFramework The first one is no problem, however when I try to install the Oracle.ManagedDataAccess.EntityFramework NuGet package, I get the following message: Could not install package 'Oracle.ManagedDataAccess.EntityFramework 12

问题 I'm looking to implement some extra logic when event handlers are added or removed to an event. I'm aware that the default implementation in .net changed recently. I'd like to keep my implementation as close to the default implementation as possible. Can anyone point me to/provide something that shows how the compliler implements events? 回答1: See this series of blog posts. In C# <4, it used simple delegate operations in lock s. In C# 4+, it uses a fancier lock-free algorithm by calling
