full screen mode, but don't cover the taskbar

Question

I have a WinForms application, which is set to full screen mode when I login.

My problem is it\'s covering the Windows taskbar also. I don\'t want my application to

Answer 1

I'm not good at explaining but this is the code I used to maximize or to full screen the winforms which would not cover up the taskbar. Hope it helps. ^^

private void Form_Load(object sender, EventArgs e)
{
    this.Height = Screen.PrimaryScreen.WorkingArea.Height;
    this.Width = Screen.PrimaryScreen.WorkingArea.Width;
    this.Location = Screen.PrimaryScreen.WorkingArea.Location;
}

Answer 2

Try without FormBorderStyle = System.Windows.Forms.FormBorderStyle.None; and comment line like :

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
    }

    private void Form1_Load( object sender, EventArgs e )
    {
        // FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;
        Left = Top = 0;
        Width = Screen.PrimaryScreen.WorkingArea.Width;
        Height = Screen.PrimaryScreen.WorkingArea.Height;
    }
}

Answer 3

If Maximizing isn't what you're looking for, then you'll need to calculate the window size yourself by checking for the location and size of the taskbar:

Answer 4

Arcanox's answer is great for a single monitor, but if you try it on any screen other than the leftmost, it will just make the form disappear. I used the following code instead.

var workingArea = Screen.FromHandle(Handle).WorkingArea;
MaximizedBounds =  new Rectangle(0, 0, workingArea.Width, workingArea.Height);
WindowState = FormWindowState.Maximized;

The only difference is I'm overriding the top & left values to be 0, 0 since they will be different on other screens.
