Question

I’m creating a windows application. In this application I’m using notifyicon and minimizing my application to system tray. In my code on button click, I process some thing in background and returns a integer value every 2 seconds. I need to display the Value over the Notifyicon .

Can anyone help me???

Answer 1

Try NotifyIcon.ShowBalloonTip method:

Displays a balloon tip with the specified title, text, and icon in the taskbar for the specified time period.

void Form1_DoubleClick(object sender, EventArgs e)
{
    notifyIcon1.Visible = true;
    notifyIcon1.ShowBalloonTip(20000, "Information", "This is the text",
        ToolTipIcon.Info );
}

If you want to change the tray icon, create an icon ondemand and set it to NotifyIcon.Icon:

to create icon you can use this codes (Updated):

public static Icon GetIcon(string text)
{
    Bitmap bitmap = new Bitmap(32, 32);

    Icon icon = SmsSender.Properties.Resources.notifficationicon;
    System.Drawing.Font drawFont = new System.Drawing.Font("Calibri", 16, FontStyle.Bold);
    System.Drawing.SolidBrush drawBrush = new System.Drawing.SolidBrush(System.Drawing.Color.White);

    System.Drawing.Graphics graphics = System.Drawing.Graphics.FromImage(bitmap);

    graphics.TextRenderingHint = System.Drawing.Text.TextRenderingHint.SingleBitPerPixel;
    graphics.DrawIcon(icon, 0, 0);            
    graphics.DrawString(text, drawFont, drawBrush, 1, 2);        
    Icon createdIcon = Icon.FromHandle(bitmap.GetHicon());

    drawFont.Dispose();
    drawBrush.Dispose();
    graphics.Dispose();
    bitmap.Dispose();

    return createdIcon;
}
