enumeration are defined. -1 and figure-2 show that there is nothing else to say. view by yourselfCodeRight Figure-1 Figure 2 The winform project file on the UI Layer is obviously prepared for the winform software. it encapsulates a set of your own controls. Of course you can do it without having. encapsulation is relatively simple, but some attribute

Source: Http://www.tuicool.com/articles/FNzURbOverviewIn C#winform programming, the practice of updating UI controls directly across threads is incorrect, and there are often "invalid inter-thread operations: access to it from a thread that is not a control created" exception. There are 4 common ways to handle updating WinForm

ObjectiveIn the rich client app, if you run some long tasks in the main thread, your application's UI will not work properly. Because the main thread is responsible for the message loop, the corresponding mouse and other events also show the UI.So we can start a thread to handle the task for a long time, but only the main thread in the rich client can update the UI's controls.WorkaroundTo put it simply, we need to update the

C # interaction between UI and work within winform 1. Use Multiple Programming Void calcpi (INT digits){//... Any token can be generated here, but if you interact with the UI, the token will be generated.} Void calcbutton_click (Object sender, eventargs E){//... This is still in the UI program, which can be replaced by

When using WCF, there are four host methods used to start the service: console, winform, IIS, and Windows service. While winform acts as the host, it usually has its own UI display and operations in addition to acting as the host for some business needs. When doing this kind of application, it is often found that calling WCF will cause

How to update the UI control value in WinForm/Silverlight multi-thread programming, winformui In a single-threaded winfom program, it is easy to set the value of a control. this. TextBox1.value = "Hello World! "; This is done, but if you do this in a new thread, for example:Private void btnSet_Click (object sender, EventArgs e) { Thread t = new Thread (new ParameterizedThreadStart (SetTextBoxValue )); // Of

In a single-threaded WINFOM program, setting the value of a control is a very easy thing to do directly with this. Textbox1.value = "Hello world!"; It's done, but if you do it in a new thread, like this:private void Btnset_click (object sender, EventArgs e){Thread t = new Thread (new Parameterizedthreadstart (Settextboxvalue));Of course, you can also write the thread t = new Thread (settextboxvalue) with an anonymous delegate;T.start ("Hello World");}void Settextboxvalue (Object obj){This.textBo

Winform implements multi-thread asynchronous UI Update (progress and status information ),Introduction It usually takes some time to perform read and write operations on a large amount of data during Winform program development. However, during this time period, the ui cannot be updated, in the user's opinion, the int

This article mainly describes the C # WinForm implementation of multi-threaded asynchronous update UI (progress and status information), small series feel very good, and now share to everyone, but also for everyone to do a reference. Let's take a look at it with a little knitting. Introduction In the WinForm program development needs to carry out a large number

The SynchronizationContext class is a base class that can provide a free-threaded context without synchronization. The purpose of the synchronization model implemented by this class is to enable asynchronous/synchronous operations within the common language runtime to take the correct behavior for different asynchronous models. This model also simplifies some of the requirements that managed applications must follow to work properly in different synchronization environments. Providers of synchro

Introduction In the WinForm program development needs to carry out a large number of data read and write operations, often will need a certain amount of time, but in this time period, the interface UI is not updated, resulting in the user appears to be in the state of suspended animation, resulting in a bad user experience. Therefore, in the application of a large number of data operations, multithrea

Given the fact that Python does have a weaker UI than WinForm. So I want to combine the WinForm of C # and the bottom development of Python (Windows platform).Try to make an RSS reader. Here: http://download.csdn.net/detail/lion_awake/8240713.Mainly from some web site crawl rss, and then parse RSS, and display on the interface.StructureThis is a C/s architecture.

Now share with you a library of my original WinForm UI, which currently has gmform form classes, and Gmvscrollbar,gmhscrollbar,gmtrackbar,gmprogressbar, Gmrollingbar a total of 5 controls, the following first look at the forms and controls.1. The chrome-style multi-tabbed browser implemented by the class library works as follows:2. Run-time multi-Theme Switch example3. Control Run EffectThe Gmform form clas

A ObjectiveThis UI library was completed by the previous company (several years ago). At that time, mainly for the development of the company's internal ERP system, redesigned to achieve all the use of the WinForm build, including form forms 6 (support skin), the base control of 25. There are many references to other open source components, and several are integrated with others ' components, and then made
