system.threading.timer

[dhol]

Hi I have done a program using thread(multithreading) with 3 text boxes, 3 labels and a button. such that when the button is clicked, Label 1 should become green color after the entered time period in text box1. Label 2 should become Yellow color after the entered time period in text box2. Label 3 should become Blue color after the entered time period in text box3. This I have done with three threads to start these processes. that is start the three threads in the buttonclick. Here is the coding part sing System; using System.Drawing; using System.Collections; using System.ComponentModel; using System.Windows.Forms; using System.Data; using System.Threading; namespace multithreadtest { /// /// Summary description for Form1. /// public class Form1 : System.Windows.Forms.Form { private System.Windows.Forms.Label label1; private System.Windows.Forms.Label label2; private System.Windows.Forms.Label label3; private System.Windows.Forms.TextBox textBox1; private System.Windows.Forms.TextBox textBox2; private System.Windows.Forms.TextBox textBox3; private System.Windows.Forms.Button button1; private Thread t1, t2, t3; /// /// Required designer variable. /// private System.ComponentModel.Container components = null; public Form1() { // // Required for Windows Form Designer support // InitializeComponent(); t1 = new Thread(new ThreadStart(colourlabel1)); t2 = new Thread(new ThreadStart(colourlabel2)); t3 = new Thread(new ThreadStart(colourlabel3)); // // TODO: Add any constructor code after InitializeComponent call // } /// /// Clean up any resources being used. /// protected override void Dispose( bool disposing ) { if( disposing ) { if (components != null) { components.Dispose(); } } base.Dispose( disposing ); } #region Windows Form Designer generated code /// /// Required method for Designer support - do not modify /// the contents of this method with the code editor. /// private void InitializeComponent() { this.label1 = new System.Windows.Forms.Label(); this.label2 = new System.Windows.Forms.Label(); this.label3 = new System.Windows.Forms.Label(); this.textBox1 = new System.Windows.Forms.TextBox(); this.textBox2 = new System.Windows.Forms.TextBox(); this.textBox3 = new System.Windows.Forms.TextBox(); this.button1 = new System.Windows.Forms.Button(); this.SuspendLayout(); // // label1 // this.label1.Font = new System.Drawing.Font

First off, it isn't right to update UI controls from a different thread. This[^] might help you understand why. To answer your question, simply drag and drop a timer from the toolbox. Set its interval property, subscribe to its Elapsed event and you should be done. Regards Senthil _____________________________ My Blog | My Articles | WinMacro
