messagebox

I was attempting to add MessageBox.Show(Message); and it was not found in my C# .net web application (button click method and also in Page_Load ).An error showing like 'The name 'MessageBox' does not exist in the current context' Do I need to add any assembly reference for this? (I am using .net framework 4). Is there any alternative method for this? Use This: System.Web.UI.ScriptManager.RegisterStartupScript(this, typeof(Page), "alert", "alert('" + Message + "')", true); Hope This help. slugster The key words in your description are web application This functionality is only available in

概述 在程序中MessageBox弹出的对话框，用于向用户展示消息，这是一个模式窗口，可阻止应用程序中的其他操作，直到用户将其关闭。但是有时候在自动化程序中，如果弹出对话框，程序将会中断，等待人工的干预，这是一个非常不好的交互体验，如果程序能够自动帮我们点击其中一个按钮，让对话框消失，该有多好。 原理 通过对话框的标题查找对话框，获取对话框的句柄，然后对话框发送指令。 涉及知识点 MessageBox 显示消息窗口（也称为对话框）向用户展示消息。这是一个模式窗口，可阻止应用程序中的其他操作，直到用户将其关闭。System.Windows.Forms.MessageBox可包含通知并指示用户的文本、按钮和符号。 Thread 创建和控制线程，设置其优先级并获取其状态。本例子主要创建一个线程，查找弹出的窗口。 WIN32 API 也就是Microsoft Windows 32位平台的应用程序编程接口。每一个服务，就是一个函数，用于和Windows进行交互。 MessageBoxButtons 是一个Enum，表示对话框上显示哪些按钮。 PostMessage 是Windows API(应用程序接口)中的一个常用函数，用于将一条消息放入到消息队列中。消息队列里的消息通过调用GetMessage和PeekMessage取得。 程序运行效果 核心代码 1 using System; 2

I am looking for a decent replacement for the standard windows YES/NO or YES/NO/CANCEL MessageBox. I have often seen these standard dialogs misused in ways such as: "To save in plain text answer YES, or to save in html answer NO". Obviously, the text should read "Save As: and the "buttons should be labeled "Text" and "HTML". It is not a yes/no question that is being asked, and although it could be phrased that way, it would not be easy to read and understand. Microsoft gives no way to change the text on the buttons. There is no fast/simple way to build a replacement from scratch... as

Some legacy code I'm stuck maintaining is stuck in an infinite loop (and thus I myself seem to be in one); I can't figure out why/how, though. Here's the app's entry point, where it instantiates the main form (frmCentral): CODE EXHIBIT A public static int Main(string [] args) { try { AppDomain currentDomain = AppDomain.CurrentDomain; currentDomain.UnhandledException += new UnhandledExceptionEventHandler(GlobalExceptionHandler); string name = Assembly.GetExecutingAssembly().GetName().Name; MessageBox.Show(string.Format("Executing assembly is {0}", name)); // TODO: Remove after testing <= this

Or do I have to use threads? (C++) No there isn't. Alternatively, you can create a "modeless dialog box". Message boxes are modal dialogs. The whole idea is that they aren't asynchronous. Assuming it was possible to do this (which it is, given the right amount of tinkering), would you want to confuse users with something that looks familiar but acts in a different way to what they expect? The question is, why do you want to do this? maybe there is a better solution. 来源： https://stackoverflow.com/questions/3556089/is-there-any-way-to-have-async-messagebox
