NET prohibits access to controls across threads in principle, because this can cause errors, and one way is to prevent the compiler from checking cross-thread access, Control.checkforillegalcrossthreadcall

Debugging the HTML page locally, if it contains JS or flash,ie, often prompts "IE has restricted this page from running scripts or ActiveX controls that can access the computer." While IE prevents local scripting from running for security reasons, it's true that, as a program developer, every time a point is allowed, it's very annoying, and it's starting to get rid of the hint.The method is: Tool – Internet

：The effect is similar to displaying the user-like interface, and we can access each individual's profile by clicking on a different nickname.For common controls, click the Git address below the article.The first step:We build a class for each person who likes to represent a personal message:Person:public class Person {public String name;public int age;}It's simple, just a name and age.Step Two:Customizing

render. If we want to repeat the ID on a dynamic page, how does ie do it?At this time, we can continue to use document. getelementbyid to get the object, except that we can only get the first object that appears in the HTML render of the objects with duplicate IDs. At this time, duplicate IDs are automatically converted into an array when being referenced. Elements with duplicate IDs exist in the array in order of render.Getelementbyid ("XXX") returns the first element whose ID attribute is "XX

// The findcontrol method in the. NET Framework class library helps us access the controls in formview: Protected void formviewincluitemcreated (Object sender, eventargs E) { Dropdownlist test; Switch (formview1.currentmode) { Case formviewmode.

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

You can use the ADO control to access the image of the SQLServer database. You can see that all the operations are performed on BMP files (the size of the database is greatly increased ).★Eagletian★The ADO English technical document translated by experts involves the key technologies used to access JPEG files in databases. It has passed the test in win98 + sqlserver desktop edition and runs well, You can us

The use of multithreading in this way also loses its original meaning.Now let's take a look at the recommended solution:public partial class Form1:form{Private delegate void Flushclient ();// AgentPublic Form1 (){InitializeComponent ();}private void Form1_Load (object sender, EventArgs e){Thread thread = new Thread (Crossthreadflush);Thread. IsBackground = true;Thread. Start ();}private void C

When we use winform applications, we usually encounter the problem of using the control information on the multi-threaded control interface. However, we cannot use traditional methods to solve this problem. I will introduce it in detail below. First, let's look at the traditional method: Public partial class form1: Form{Public form1 (){Initializecomponent ();}Private void form1_load (Object sender, eventargs E){Thread thread = new thread (threadfuntion );Thread. isbackground = true;Thread. Start
