Notification from Icon in statusbar

Introduction

Here is an article for displaying notification from statusbar icon. And when user will double click on that icon it will open a web application. And on right click it will display menu to Hide, Show alerts as well Exit the alerts. So we can say that here we are going to implement an application which will work together as window based as well web based application. Here the alert will be displayed from database. And when there will not any mess in database it will not display any notification. But when any mess will come in database it will pop up notification.

Here is a snipshots for the same.

When user right click on Icon.

Using the code

First we will create a window application.Name the window application as AlertMessControl. Now add one form name it as AlertMess.

Add below controls and set appropriate properties to controls:

//

// Controls of window form

//


Timer :
 this.tmrAlert.Enabled = true;
 this.tmrAlert.Interval = 2000;
 this.tmrAlert.Tick += new System.EventHandler(this.tmrAlert_Tick);

Label :
 this.lblStatus.Name = "lblStatus";

NotifyIcon :
 this.alertNot.BalloonTipIcon = System.Windows.Forms.ToolTipIcon.Info;
 this.alertNot.BalloonTipText = "Task Arrived";
 this.alertNot.BalloonTipTitle = "New Task";
 this.alertNot.Text = "Test all task";
 this.alertNot.Visible = true;
 this.alertNot.MouseDoubleClick += new System.Windows.Forms.MouseEventHandler(this.alertNot_MouseDoubleClick);

Label :
 this.lblTotal.AutoSize = true;
 this.lblTotal.Name = "lblTotal";
 this.lblTotal.Text = "0";
 this.lblTotal.Visible = false;

Form Property :
 this.ControlBox = false;
 this.Name = "AlertMess";
 this.Opacity = 0.01;
 this.ShowInTaskbar = false;
 this.Text = "AlertMess";
 this.WindowState =   System.Windows.Forms.FormWindowState.Minimized;


///Now in the codebehind file AlertMess.cs write below code.
