Step 1: Click New Project, then select Visual C# on the left, then Windows and then select Windows Forms Application. Name your project "AlarmClock" and then click OK
Step 2: Design your form as below
Step 3: Add code to handle your form as below
using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Threading.Tasks; using System.Windows.Forms; namespace AlarmClock { public partial class Form1 : Form { System.Timers.Timer timer; public Form1() { InitializeComponent(); } private void Form1_Load(object sender, EventArgs e) { //Init timer timer = new System.Timers.Timer(); timer.Interval = 1000; timer.Elapsed += Timer_Elapsed; } private void Timer_Elapsed(object sender, System.Timers.ElapsedEventArgs e) { //Update timer DateTime currentTime = DateTime.Now; DateTime userTime = dateTimePicker.Value; if (currentTime.Hour == userTime.Hour && currentTime.Minute == userTime.Minute && currentTime.Second == userTime.Second) { timer.Stop(); UpdateLable upd = UpdateDataLable; if (lblStatus.InvokeRequired) Invoke(upd, lblStatus, "Stop"); MessageBox.Show("Ring ring ring...", "Message", MessageBoxButtons.OK, MessageBoxIcon.Information); } } //Update label control delegate void UpdateLable(Label lbl, string value); void UpdateDataLable(Label lbl,string value) { lbl.Text = value; } private void btnStart_Click(object sender, EventArgs e) { timer.Start(); lblStatus.Text = "Running..."; } private void btnStop_Click(object sender, EventArgs e) { timer.Stop(); lblStatus.Text = "Stop"; } } }
The System.Timers.Timer component raises the Elapsed event, based on the value of the Interval property. You can handle this event to perform the processing you need.
The System.Timers.Timer class has the same resolution as the system clock. This means that the Elapsed event will fire at an interval defined by the resolution of the system clock if the Interval property is less than the resolution of the system clock
